5. Replace the pressure cap. Be sure the pressure
cap is hand-tight and fully seated.
Check the level in the surge tank when the system
has cooled down. If the coolant is not at the proper
level, repeat Steps 1 through 4, then reinstall the
pressure cap. If the coolant is not at the proper
level when the system cools down again, see your
dealer/retailer.
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
Engine Overheating
The vehicle has several indicators to warn of engine
overheating.
There is an engine coolant temperature gage on
the instrument panel cluster. SeeEngine Coolant
Temperature Gage on page 3-41. The vehicle may
also display a COOLANT OVER TEMPERATURE
message on the Driver Information Center (DIC).
SeeDIC Warnings and Messages on page 3-54
for more information.You may decide not to lift the hood but to get service
help right away. SeeRoadside Assistance Program
on page 7-7.
If you do decide to lift the hood, make sure the vehicle
is parked on a level surface.
Then check to see if the engine cooling fan is running.
If the engine is overheating, the fan should be running.
If it is not, do not continue to run the engine and have the
vehicle serviced.
Notice:Engine damage from running your engine
without coolant is not covered by your warranty.
SeeOverheated Engine Protection Operating Mode
on page 5-41for information on driving to a safe
place in an emergency.
Notice:If the engine catches re while driving
with no coolant, the vehicle can be badly damaged.
The costly repairs would not be covered by the
vehicle warranty. SeeOverheated Engine Protection
Operating Mode on page 5-41for information on
driving to a safe place in an emergency.

Tires
Your new vehicle comes with high-quality tires
made by a leading tire manufacturer. If you ever
have questions about your tire warranty and where
to obtain service, see your vehicle Warranty booklet
for details. For additional information refer to the tire
manufacturer.
{CAUTION:
Poorly maintained and improperly used
tires are dangerous.
Overloading your tires can cause
overheating as a result of too much
exing. You could have an air-out and
a serious accident. SeeLoading the
Vehicle on page 4-22.
CAUTION: (Continued)
CAUTION: (Continued)
Underin ated tires pose the same danger
as overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be
checked when your tires are cold. See
Inflation - Tire Pressure on page 5-70.
Overin ated tires are more likely to
be cut, punctured, or broken by a sudden
impact — such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents.
If your tread is badly worn, or if your tires
have been damaged, replace them.
SeeHigh-Speed Operation on page 5-72for
in ation pressure adjustment for high speed
driving.
