Roadside Emergencies
5. Turn off the ignition.
To change the tire:
Note: Passengers should not remain in the vehicle when the vehicle is
being jacked.
1. Block both the front and rear of
the wheel diagonally opposite the
flat tire. For example, if the right
front tire is flat, block the left rear
wheel.
2. Remove any wheel trim by inserting the flat end of the lug nut wrench
under the wheel trim flange, then twisting the wrench to pry it off.
3. Loosen, but do not remove, the
wheel lug nuts by turning them
one-half turn counterclockwise.
Slide the jack handle and jack
handle extension together. Slide the
jack handle assembly into the end of
the lug nut wrench. To disconnect,
depress the button and pull the pieces apart.
4. Position the jack properly and insert the jack handle into the opening
in the thumbwheel at the base of the jack. Turn the handle clockwise
until the tire is a maximum of 25 mm (1 inch) off the ground.
To lessen the risk of personal injury, do not put any part of your
body under the vehicle while changing a tire. Do not start the
engine when your vehicle is on the jack. The jack is only meant for
changing the tire.
