All Rights Reserved. 3 Index A good place to quickly locate information about the vehicle is the Index in the back of the manual. It is an alphabetical list of what is in the manual and the page number where it can be found. In the caution area, we tell you what the hazard is. Then we tell you what to do to help avoid or reduce the hazard. Please read these cautions. If you do not, you or others could be hurt. You will also find a circle with a slash through it in this book. This safety symbol means "Do Not," "Do Not do this" or "Do Not let this happen." Safety Warnings and Symbols There are a number of safety cautions in this book. We use a box and the word CAUTION to tell about things that could hurt you if you were to ignore the warning. {CAUTION: These mean there is something that could hurt you or other people. 4 Vehicle Damage Warnings Also, in this manual you will find these notices: Notice: These mean there is something that could damage your vehicle. A notice tells about something that can damage the vehicle. Many times, this damage would not be covered by your vehicle's warranty, and it could be costly. But the notice will tell what to do to help avoid the damage. When you read other manuals, you might see CAUTION and NOTICE warnings in different colors or in different words. There are also warning labels on the vehicle. They use the same words, CAUTION or NOTICE. Vehicle Symbols The vehicle has components and labels that use symbols instead of text. Symbols are shown along with the text describing the operation or information relating to a specific component, control, message, gage, or indicator.

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. · Raise or lower the rear part of the seat cushion by moving the rear of the control up or down. · Raise or lower the entire seat by moving the entire control up or down. Driver's Side shown, Passenger Side similar 9 Power Lumbar Heated Seats If your vehicle has this feature, the buttons are located on the climate control panel. Your driver's seat may have power lumbar. The control is located on the outboard side of the seat cushion. Press the front of the control to increase lumbar support. Press the rear of the control to decrease lumbar support. Keep in mind that as your seating position changes, as it may during long trips, so should the position of your lumbar support. Adjust the seat as needed. 10 Press the button once to activate the high heat setting. Both indicator lights on the button will come on. Press the button again to select the lower temperature setting. Only one indicator light will come on. Press the button a third time to turn the heat off. This feature only works when the ignition is on. Reclining Seatbacks Your seats have manual reclining seatbacks. The lever used to operate them is located on the outboard side of the seats. {CAUTION: You can lose control of the vehicle if you try to adjust a manual driver's seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you do not want to. Adjust the driver's seat only when the vehicle is not moving. {CAUTION: If the seatback is not locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always push and pull on the seatback to be sure it is locked. Driver's Side shown, Passenger Side similar To recline the seatback, do the following: 1. Lift the recline lever. 2. Move the seatback to the desired position, then release the lever to lock the seatback in place. 3. Push and pull on the seatback to make sure it is locked. 11 To return the seatback to an upright position, do the following: 1. Lift the lever fully without applying pressure to the seatback and the seatback will return to the upright position. 2. Push and pull on the seatback to make sure it is locked. {CAUTION: Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts cannot do their job when you are reclined like this. The shoulder belt cannot do its job because it will not be against your body. Instead, it will be in front of you. In a crash, you could go into it, receiving neck or other injuries. The lap belt cannot do its job either. In a crash, the belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones. This could cause serious internal injuries. For proper protection when the vehicle is in motion, have the seatback upright. Then sit well back in the seat and wear your safety belt properly. Do not have a seatback reclined if your vehicle is moving. 12 Head Restraints Pull the head restraint up to raise it. To lower the head restraint, press the button, located on the top of the seatback, and push the head restraint down. 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. 13 Center Seat Rear Seats Split Folding Rear Seat If your vehicle has this feature, both sides of the rear seatback can be folded down. This gives direct access to the trunk. Make sure the front seats are not reclined. If they are, the rear seatback(s) may not fold down all the way. Notice: Folding a rea ...
