WARNING
1=
You or your passengers could be injured
while changing a wheel if you do not fol-
low these safety precautions:
- If you have a flat tire, move a safe dis-
tance off the road. Turn off the engine,
turn the emergency flashers on and use
other warning devices to alert other mo-
torists.
- Make sure that passengers wait in a safe
place away from the vehicle and well
away from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the
jack, always fully set the parking brake
and block the wheel diagonally opposite
the wheel being changed. When one
front wheel is lifted off the ground , plac-
ing the Automatic Transmission in P
(Park) will not prevent the vehicle from
moving.
- Before you change a wheel, be sure the
ground is level and firm. If necessary,
use a sturdy board under the jack.
- Always store the vehicle tool kit, the jack
and the replaced tire in the luggage com-
partment ¢ page 132.

Tips
