ability, to the point where the ratchet/slip occurs, if possible. The spare
tire carrier will not allow you to overtighten. If the spare tire carrier
ratchets or slips with little effort, take the vehicle to your dealer for
assistance at your earliest convenience.
4. Check that the tire lies flat against the frame and is properly
tightened. Try to push or pull, then turn the tire to be sure it will not
move. Loosen and retighten, if necessary. Failure to properly stow the
spare tire may result in failure of the winch cable and loss of the tire.
5. If your vehicle is equipped with a spare tire lock and key, be sure to
install the spare tire lock into the bumper drive tube with the spare tire
lock key and jack handle.
6. Repeat this tightness check procedure when servicing the spare tire
pressure (every six months, per scheduled maintenance guide), or at any
time that the spare tire is disturbed through service of other
components.
Re-stowing the jack and tools
1. Unblock the wheels.
2. Replace beauty cap, stow the jack and tools in their respective
locations, making sure they are fully secured so they do not rattle when
you drive.
JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
Batteries contain sulfuric acid which can burn skin, eyes and
clothing, if contacted.
Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; also, the
catalytic converter may become damaged.
