Safety Warnings and Symbols You will find a number of safety cautions in this book. We use a box and the word CAUTION to tell you about things that could hurt you if you were to ignore the warning. Index A good place to look for what you need is the Index in back of the manual. It's an alphabetical list of what's in the manual, and the page number where you'll find it. CAUTION: These mean there is something that could hurt you or other people. 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 don't, you or others could be hurt. iii yellowblue You will also find a circle with a slash through it in this book. This safety symbol means "Don't," "Don't do this" or "Don't let this happen." In the notice area, we tell you about something that can damage your vehicle. Many times, this damage would not be covered by your warranty, and it could be costly. But the notice will tell you 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. You'll also see warning labels on your vehicle. They use the same words, CAUTION or NOTICE. Vehicle Damage Warnings Also, in this book you will find these notices: NOTICE: These mean there is something that could damage your vehicle. iv yellowblue Vehicle Symbols These are some of the symbols you may find on your vehicle.

Vertical Control: If your vehicle has the power reclining seats, you can use this button to adjust the angle of the seatback. Move the reclining front seatback rearward by moving the button toward the rear of the vehicle. Move the seatback forward by moving the button toward the front of the vehicle. See "Reclining Seatbacks" in the Index for further information. Horizontal Control: If your vehicle has a power seat, you can adjust it with this control located at the outside edge of the seat. 1-4 yellowblue Power Lumbar Control (If Equipped) If you have power lumbar adjustment, you can increase or decrease lumbar support in an area of the lower seatback.

If your vehicle has power seats with a power recliner, see "Power Seats" in the Index for further information on how to operate the reclining seatback feature. 1-7 yellowblue CAUTION: Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can't do their job when you're reclined like this. The shoulder belt can't do its job. In a crash, you could go into it, receiving neck or other injuries. The lap belt can't 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. But don't have a seatback reclined if your vehicle is moving. 1-8 yellowblue Head Restraints Slide the head restraint up or down so that the top of the restraint is closest to the top of your ears. This position reduces the chance of a neck injury in a crash. On some models, the head restraints tilt forward and rearward also. To tilt the head restraints forward, grasp the top of the restraint and move it forward to where you want it to go until you hear a click. It will then be locked into that position until you need to move it again. Pulling it forward past the last position will allow the restraint to return to its upright position. The seatbacks fold forward to let you access the rear of the cab. To fold a front seatback forward, pull this lever forward and fold the seatback forward. Seatback Latches CAUTION: If the seatback isn't locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked. To return the seatback to the upright position, just push the seatback rearward until it latches. After returning the seatback to its upright position, pull the seatback forward to make sure it is locked. 1-9 yellowblue Easy Entry Seat (Extended Cab Only) CAUTION: If any ...
