WARNING!

A loose tire or jack thrown forward in a collision or
hard stop, could endanger the occupants of the vehicle.
Always stow the jack parts and the spare tire in the
places provided.

Road Tire Installation

1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the cone shaped end of

the nut toward the wheel. Lightly tighten the lug nuts.

WARNING!

To avoid the risk of forcing the vehicle off the jack, do
not tighten the wheel nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in serious injury.

3. Lower the vehicle to the ground by turning the jack

handle counterclockwise.

4. Finish tightening the lug nuts. Push down on the

wrench while at the end of the handle for increased

leverage. Tighten the lug nuts in a star pattern until each

nut has been tightened twice. For the correct lug nut

torque refer to “Torque Specifications” in “Technical

Specifications”. If in doubt about the correct tightness,

have them checked with a torque wrench by your

authorized dealer or service station.

5. After 25 miles (40 km), check the lug nut torque with a

torque wrench to ensure that all lug nuts are properly

seated against the wheel.

JUMP STARTING

If your vehicle has a discharged battery, it can be jump started

using a set of jumper cables and a battery in another vehicle, or

by using a portable battery booster pack. Jump starting can be

dangerous if done improperly, so please follow the procedures

in this section carefully.

WARNING!

Do not attempt jump starting if the battery is frozen. It
could rupture or explode and cause personal injury.

CAUTION!

Do not use a portable battery booster pack or any other
booster source with a system voltage greater than 12
