Manual Passenger Seat

Lift the bar located under the front of the seat to unlock it. Slide the seat to where you want it and release the bar. Try to move the seat with your body to be sure the seat is locked in place.

Power Seats

Driver’s Seat with Power Seat Control, Power Recline, and Power Lumbar shown

If the vehicle has power seats, the controls used to operate them are located on the outboard side of the seats. To adjust the seat, do any of the following:

• Move the seat forward or rearward by sliding the control forward or rearward.
• Raise or lower the front part of the seat cushion by moving the front of the control up or down.

Heated and Cooled Seats

The front seats may have the heated and cooled seat feature. To heat or cool the seats, the ignition must be on. The buttons are located on the front doors forward of the door handle.Driver’s Side Buttons shown

(Heated Seat Cushion and Seatback): Press this button to heat the seat cushion and seatback.
(Heated Seatback): Press this button to heat the seatback.
Press the button to turn on the desired feature. A light on that button will display to show which feature is on. There are three temperature settings for each feature. A column of three lights next to the buttons will display which setting the feature is in: high, medium, or low. Three lights indicate the highest setting, two lights indicate medium and one light indicates the lowest setting.

When you press a button, the feature will turn on at the highest setting. Each time you press the button, the feature will decrease one temperature setting. To turn the feature off, keep pressing the button until the display lights turn off. If your vehicle has remote vehicle start and is started using the remote keyless entry transmitter, the front heated seats will be turned on to the high setting if it is cold outside.

See “Remote Vehicle Start” under Remote Keyless Entry (RKE) System Operation on page 95. When the key is inserted into the ignition and the ignition is turned on, the heated seat feature will turn off. To turn the heated seat feature back on, press the desired button.

Memory Seat and Mirrors

Your vehicle may have the memory package

The controls for this feature are located on the driver’s door panel and are used to program and recall memory settings for the driver’s seat and the outside mirrors.

To save your positions in memory, do the following:

1. Adjust the driver’s seat, including the seatback recliner and lumbar, and both outside mirrors to your preferred position.
2. Press and hold button 1 until two beeps sound through the driver’s side front speaker to let you know that the position has been stored.

A second seating and mirror position can be programmed by repeating the above steps and pressing button 2 for a second driver. To recall your memory positions, the vehicle must be in PARK (P). Press and release either button 1 or button 2 corresponding to the desired driving position. The seat and outside mirrors will move to the position previously stored for the identified driver.

You will hear a single beep. If you use the remote keyless entry transmitter to enter your vehicle and the remote recall memory feature is on, automatic seat and mirror movement will occur. See “MEMORY SEAT RECALL” under DIC Vehicle Customization on page 231 for more information.

To stop the recall movement of the memory feature at any time, press one of the power seat controls, memory buttons, or power mirror buttons. If something has blocked the driver’s seat while recalling a memory position, the driver’s seat recall may stop working.

If this happens, press the appropriate control for the area that is not recalling for two seconds, after the obstruction is removed. Then try recalling the memory position again by pressing the appropriate memory button. If the memory position is still not recalling, see your dealer for service.

Head Restraints

Adjust the head restraint so that the top of the restraint is at the same height as the top of the occupant’s head. This position reduces the chance of a neck injury in a crash.

Why Safety Belts Work

When you ride in or on anything, you go as fast as it goes.Take the simplest vehicle. Suppose it is just a seat on wheels.Put someone on it.

Get it up to speed. Then stop the vehicle. The rider does not stop.The person keeps going until stopped by something. In a real vehicle, it could be the windshield…

or the instrument panel…

or the safety belts! With safety belts, you slow down as the vehicle does. You get more time to stop. You stop over more distance, and your strongest bones take the forces. That is why safety belts make such good sense.

Questions and Answers About Safety Belts

• Q: Will I be trapped in the vehicle after an accident if I am wearing a safety belt?
  A: You could be — whether you are wearing a safety belt or not. But you can unbuckle a safety belt,
  even if you are upside down. And your chance of being conscious during and after an accident, so
  you can unbuckle and gout, is much greater if you are belted.
• Q: If my vehicle has airbags, why should I have to wear safety belts?
  A: Airbags are supplemental systems only; so they work with safety belts — not instead of them. Every airbag system ever offered for sale has required the use of safety belts. Even if you are in a vehicle that has airbags, you still have to buckle up to get the most protection. That is true not only in frontal collisions but especially in side and other collisions.
• Q: If I am a good driver, and I never drive far from home, why should I wear safety belts?
  A: You may be an excellent driver, but if you are in an accident — even one that is not your fault — you and your passengers can be hurt. Being a good driver does not protect you from things beyond your control, such as bad drivers. Most accidents occur within 25 miles (40 km) of home. The greatest number of serious injuries and deaths occur at speeds of less than 40 mph (65 km/h). Safety belts are for everyone.

How to Wear Safety Belts Properly

This part is only for people of adult size. Be aware that there are special things to know about safety belts and children. And there are different rules for smaller children and babies. If a child will be riding in your vehicle, see Older Children on page 43 or Infants and Young Children on page 46. Follow those rules for everyone’s protection. First, you will want to know which restraint systems your vehicle has. We will start with the driver position.

Driver Position

Lap-Shoulder Belt

The driver has a lap-shoulder belt. Here is how to wear it properly.

1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see how, see “Seats” in the Index.
3. Pick up the latch plate and pull the belt across you. Do not let it get twisted. The lap-shoulder belt may lock if you pull the belt across you very quickly. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly.
4. Push the latch plate into the buckle until it clicks. Be sure to use the correct buckle when buckling your lap-shoulder belt. If you find that the latch plate will not go fully into the buckle, see if you are using the buckle for the center passenger position. Pull up on the latch plate to make sure it is secure. If the belt is not long enough, see Safety Belt Extender on page 42. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.
5. Move the shoulder belt height adjuster to the height that is right for you. Improper shoulder belt height adjustment could reduce the effectiveness of the safety belt in a crash. See Shoulder Belt Height Adjustment on page 33.
6. To make the lap part tight, pull up on the shoulder belt. It may be necessary to pull stitching on the safety belt through the latch plate to fully tighten the lap belt on smaller occupants

Rear Seat Passengers

Rear seat passengers need to buckle up! Accident statistics show that unbelted people in the rear seat are hurt more often in crashes than those who are wearing safety belts. Rear passengers who are not safety belted can be thrown out of the vehicle in a crash. And they can strike others in the vehicle who are wearing safety belts.

Lap-Shoulder Belt

All rear seating positions have lap-shoulder belts. Here is how to wear one properly.

1. Pick up the latch plate and pull the belt across you. Do not let it get twisted. The shoulder belt may lock if you pull the belt across you very quickly. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly.
2. Push the latch plate into the buckle until it clicks. The latch plates for the safety belts in each rear seating position vary in size. If the center rear or the left rear latch plate is inserted into the incorrect buckle, the plate will not latch properly. Be sure you are using the correct buckle and that the latch plate clicks when inserted into the buckle.When the shoulder belt is pulled out all the way, it will lock. If it does, let it go back and start again. Pull up on the latch plate to make sure it is secure. If the belt is not long enough, see Safety Belt Extender on page 42. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to.
3. To make the lap part tight, pull up on the shoulder part.

Rear Safety Belt Comfort Guides

Rear shoulder belt comfort guides may provide added safety belt comfort for older children who have outgrown booster seats and for small adults. When installed on a shoulder belt, the comfort guide better positions the belt away from the neck and head.

There is one guide for each outside passenger position in the rear seat. Here is how to install a comfort guide to the safety belt:

1. Remove the guide from its storage pocket on the rear side of the seatback.
2. Slide the guide under and past the belt. The elastic cord must be under the belt. Then, place the guide over the belt, and insert the two edges of the belt into the slots of the guide.
3. Be sure that the belt is not twisted and that it lies flat. The elastic cord must be under the belt and the guide on top.
4. Buckle, position, and release the safety belt as described in Rear Seat Passengers on page 36. Make sure that the shoulder belt crosses the shoulder. To remove and store the comfort guide, squeeze the belt edges together so that you can take them out of the guide. Slide the guide into its storage pocket on the side of the seatback.

Child Restraints

Older Children

• Q: What is the proper way to wear safety belts?
  A: An older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should fit snugly below the hips, just touching the top of the thighs. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash.According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seating positions. In a crash, children who are not buckled up can strike other people who are buckled up or can be thrown out of the vehicle. Older children need to use safety belts properly.
• Q: What if a child is wearing a lap-shoulder belt, but the child is so small that the shoulder belt is very close to the child’s face or neck?
  A: If the child is sitting in a seat next to a window, move the child toward the center of the vehicle. Also, see Rear Safety Belt Comfort Guides on page 39. If the child is sitting in the center rear seat passenger position, move the child toward the safety belt buckle. In either case, be sure that the shoulder belt still is on the child’s shoulder, so that in a crash the child’s upper body would have the restraint that belts provide.

Lower Anchors

Lower anchors (A) are metal bars built into the vehicle. There are two lower anchors for each LATCH seating position that will accommodate a child restraint with lower attachments (B).

Top Tether Anchor

A top tether (A, C) anchors the top of the child restraint to the vehicle. A top tether anchor is built into the vehicle. The top tether attachment (B) on the child restraint connects to the top tether anchor in the vehicle to reduce the forward movement and rotation of the child restraint during driving or in a crash. Your child restraint may have a single tether (A) or a dual tether (C). Either will have a single attachment (B) to secure the top tether to the anchor.

Resuming a Set Speed

Suppose you set the cruise control at a desired speed and then you apply the brake. This shuts off the cruise control, but it does not need to be reset. Once you are driving about 25 mph (40 km/h) or more, press the +RES button on the steering wheel. The vehicle will go back to your chosen speed and stay there. Increasing Speed While Using Cruise Control

To increase the cruise speed while using cruise control:

• Press and hold the +RES button on the steering wheel until you reach your new desired speed,  then release it.
• To increase vehicle speed in small increments, press the +RES button.

Reducing Speed While Using Cruise Control

To reduce your speed while using cruise control:

• Press and hold the SET– button on the steering wheel until you reach the lower speed you want, then release it.
• To slow down in very small amounts, press the SET– button on the steering wheel briefly. Each time this is done, you will go about 1 mph (1.6 km/h) slower.

Passing Another Vehicle While Using Cruise Control

Use the accelerator pedal to increase vehicle speed. When you take your foot off the pedal, the vehicle will slow down to the cruise speed you set earlier.

Fog Lamps

(Fog Lamps): If your vehicle has fog lamps, the button is located on the exterior lamp’s control. The exterior lamp control is located on the instrument panel to the left of the steering column. Your ignition must be in RUN for the fog lamps to illuminate. To turn the fog lamps on, press the exterior lamps button. A light will come on in the instrument panel cluster to let you know that the fog lamps are on. See Instrument Panel Cluster on page 194.

Press the exterior lamps button again to turn the fog lamps off. The ignition must be in RUN and the parking lamps must be on for your fog lamps to work. The fog lamps will go off when you change to high-beam headlamps. Some localities have laws that require the headlamps to be on along with the fog lamps.

Cornering Lamps

If your vehicle has this feature, the cornering lamps come on when: the headlamps or parking lamps are on, the vehicle is not in PARK (P), and you signal a turn with the turn signal/multifunction lever. They provide more light for cornering.

Exterior Lighting Battery Saver

If the exterior lamp button has been left on, the exterior lamps will turn off about 10 minutes after the ignition is turned OFF and a door has been opened. This protects against draining the battery in case you have accidentally left the headlamps or parking lamps on. If you need to leave the lamps on for more than 10 minutes, use the manual control to turn the lamps back on after the ignition is turned to OFF and any door is opened.

Climate Controls

Climate Control System

With this system, you can control the heating, cooling, and ventilation of your vehicle. If your vehicle has the remote start feature and it is activated, the climate control system will heat and cool the inside of the vehicle, using the previous system settings before the vehicle was turned off.

The rear window defogger will be turned on by the climate control system when it is cold outside. If the vehicle has heated seats, they will also turn on. Cooled seats are not activated during a remote start. Normal operation of the system will return after the key is turned to the RUN position. See Remote Keyless Entry (RKE) System Operation on page 95 for more information.

Sensors

The solar sensor, located in the defrost grille, middle of the instrument panel, monitors the solar radiation. Do not cover the solar sensor or the system will not work properly. There is also an interior temperature sensor located next to the steering wheel that measures the temperature of the air inside your vehicle.

Outlet Adjustment

Use the levers, located in the middle of the front outlets, to change the direction of the airflow. Use the thumbwheel located between the outlets to turn them on and off. If your vehicle has rear seat outlets, adjust the direction of the airflow using the lever in the center of each outlet.

Operation Tips

• Clear away any ice, snow, or leaves from the air inlets at the base of the windshield that could block the flow of air into your vehicle.
• The use of non-GM-approved hood deflectors can adversely affect the performance of the system.
• Keep the path under the front seats clear of objects to help circulate the air inside the vehicle better.
