Road Tire Installation
1. Mount the road tire on the axle.
2. Install the remaining wheel bolts with the threaded end
of the wheel bolt toward the wheel. Lightly tighten the
wheel bolts.
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 wheel bolts. Push down on the
wrench while at the end of the handle for increased
leverage. Tighten the wheel bolts in a star pattern until
each wheel bolt has been tightened twice. If in doubt
about the correct tightness, have them checked with a
torque wrench by an authorized dealer or service sta-
tion.
Refer to “Torque Specifications” in “Technical Specifica-
tions” for the proper lug bolt torque.
5. Lower the jack until it is free. Remove the wheel chocks.
Reassemble the lug wrench to the jack assembly and
stow it in the spare tire area. Secure the assembly using
the means provided. Release the parking brake before
driving the vehicle.
6. After 25 miles (40 km), check the wheel bolt torque with
a torque wrench to ensure that all wheel bolts are
properly seated against the wheel.
TIRE SERVICE KIT IF EQUIPPED
Small punctures up to 1/4 inch (6 mm) in the tire tread can
be sealed with Tire Service Kit. Foreign objects (e.g., screws
or nails) should not be removed from the tire. Tire Service
Kit can be used in outside temperatures down to approxi-
mately -4°F (-20°C).
This kit will provide a temporary tire seal, allowing you to
drive your vehicle up to 100 miles (160 km) with a
maximum speed of 55 mph (90 km/h).
