radiator ller neck is low, add
more of the proper DEX-COOL
coolant mixture through the
ller neck until the level is back
up to the base of the ller
neck. Replace the pressure cap.
Be sure to secure it tightly.
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 3-40.The vehicle may also display
an ENGINE OVERHEATED
IDLE ENGINE and ENGINE
OVERHEATED STOP ENGINE

Center (DIC). SeeDIC Warnings
and Messages on page 3-56.
You may decide not to lift the hood

instead get service help right away.
SeeRoadside Assistance Program
on page 7-6.
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 fans are running. If the
engine is overheating, both fans
should be running. If they are
not, do not continue to run the
engine and have the vehicle
serviced.Notice:Engine damage from
running the engine without

hold the wiper arm in position,
and push the blade away
from the wiper arm.
3. Replace the wiper blade.
4. Return the wiper arm and blade

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
vehicle’s tires can cause
overheating as a result
of too much exing. You
could have an air-out and
a serious accident. See
Loading the Vehicle on
page 4-16.
(Continued)
CAUTION (Continued)
Underinated 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 vehicle’s tires are
cold. SeeInflation - Tire
Pressure on page 5-41.
Overinated 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 the tire’s tread
is badly worn, or if your
vehicle’s tires have been
damaged, replace them.
