secure the spare tire with the special wing
nut torqued to 3.7 ft-lbs (5 N·m), reinstall
the jack and tool kit foam tray, and latch the
rear load floor cover.
NOTE:
Do not drive with the spare tire installed for
more than 50 miles (80 km) at a max speed of
50 mph (80 km/h).
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. Have the deflated (flat) tire repaired
or replaced immediately.

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. Refer to "Wheel And Tire Torque Specifi-
cations" in "Technical Specifications" for
proper lug nut torque for further
information.
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.
