CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads HOT
(H), pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on HOT (H), and you hear continuous
chimes, turn the engine off immediately and call for
service.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle the lug nuts/bolts should be torqued using a
properly calibrated torque wrench.

After 25 miles (40 km) check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly seated
against the wheel.

TIRE SERVICE KIT — IF EQUIPPED
Small punctures up to ¼” (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 65 mph (106 km/h).
