IN CASE OF EMERGENCY 309
Road Wheel Installed In Spare Location
NOTE:
Double check to ensure the tire is snug against
the underbody of the vehicle. Damage to the
winch cable may result if the vehicle is driven
with the tire loose.
12. Lower the jack to the fully closed position.
13. Return the Jack and tools back into the jack
storage bin. Reinstall the jack storage cover
by firmly pushing down until the two side
clips lock into position.
14. 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.
15. Have the aluminum road wheel and tire
repaired as soon as possible and properly
secure the spare tire, jack and tool kit.
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).
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 st-arting
can be dangerous if done improperly, so please
follow the procedures in this section carefully.
NOTE:
When using a portable battery booster pack,
follow the manufacturer's operating instruc-
tions and precautions.
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.
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 Volts or damage to
the battery, starter motor, alternator or
electrical system may occur.
