A. Engine Cooling Fan (Out of View)
B. Engine Coolant Surge Tank and Pressure Cap
{WARNING
An electric engine cooling fan
under the hood can start up even
when the engine is not running
and can cause injury. Keep
hands, clothing, and tools away
from any underhood electric fan.
If the coolant inside the coolant
surge tank is boiling, do not do
anything else until it cools down.
The vehicle should be parked on
a level surface.
The coolant level should be
between the MIN and MAX lines.
If it is not, the vehicle may have
a leak at the radiator hoses, heater
hoses, radiator, water pump,
or somewhere else in the cooling
system.
{WARNING
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the engine if there
is a leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
If there seems to be no leak,
with the engine on, check to
see if the electric engine cooling
fan is running. If the engine is
overheating, the fan should be
running. If it is not, the vehicle
needs service. Turn off the engine.

Vehicle Care 10-19
Notice:Using coolant other
than DEX-COOL®can cause
premature engine, heater core,
or radiator corrosion. In addition,
the engine coolant could require
changing sooner, at 50 000 km
(30,000 miles) or 24 months,
whichever occurs first. Any
repairs would not be covered
by the vehicle warranty. Always
use DEX-COOL (silicate-free)
coolant in the vehicle.
Engine Coolant
The cooling system in the vehicle
is filled with DEX-COOL®engine
coolant. This coolant is designed to
remain in the vehicle for 5 years or
240 000 km (150,000 mi), whichever
occurs first.
The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
see Engine Overheating on
page 10‑22
What to Use
{WARNING
Adding only plain water or some
other liquid to the cooling system
can be dangerous. Plain water
and other liquids, can boil before
the proper coolant mixture will.
The vehicle's coolant warning
system is set for the proper
coolant mixture. With plain water
or the wrong mixture, the engine
could get too hot but you would
not get the overheat warning.
The engine could catch fire and
you or others could be burned.
Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
coolant. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
coolant. If using this mixture,
nothing else needs to be added.
This mixture:.Gives freezing protection down
to
−37°C (−34°F), outside
temperature.
.Gives boiling protection up
to 129°C (265°F), engine
temperature.
.Protects against rust and
corrosion.
.Will not damage aluminum parts.
.Helps keep the proper engine
temperature.
Notice: If an improper coolant
mixture is used, the engine could
overheat and be badly damaged.
The repair cost would not be
covered by the vehicle warranty.
Too much water in the mixture
can freeze and crack the engine,
radiator, heater core, and other
parts.

10-20 Vehicle Care
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible
in the coolant surge tank. If the
coolant inside the coolant surge
tank is boiling, do not do anything
else until it cools down. If coolant
is visible but the coolant level is
not at the indicated mark, add a
50/50 mixture of clean, drinkable
water and DEX-COOL coolant at the
coolant surge tank, but be sure the
cooling system is cool before this is
done. SeeEngine Overheating on
page 10‑22 for more information.
The coolant surge tank is located
in the engine compartment on
the driver side of the vehicle.
See Engine Compartment Overview
on page 10‑6 for more information
on location.
How to Add Coolant to the
Coolant Surge Tank
Notice: This vehicle has a
specific coolant fill procedure.
Failure to follow this procedure
could cause the engine to
overheat and be severely
damaged.
If no problem is found, check to see
if coolant is visible in the coolant
surge tank. If coolant is visible
but the coolant level is not at
the indicated level mark, add a
50/50 mixture of clean, drinkable
water and DEX-COOL coolant at
the coolant surge tank, but be sure
the cooling system, including the
coolant surge tank pressure cap,
is cool before you do it.
{WARNING
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. They are
under pressure, and if you turn
the coolant surge tank pressure
cap —even a little —they can
come out at high speed. Never
turn the cap when the cooling
system, including the coolant
surge tank pressure cap, is hot.
Wait for the cooling system and
coolant surge tank pressure cap
to cool if you ever have to turn
the pressure cap.

10-22 Vehicle Care
2. Then keep turning the pressurecap slowly and remove it.
3. Fill the coolant surge tank with the proper DEX-COOL
coolant mixture to the indicated
level mark.
4. With the coolant surge tank pressure cap off, start the
engine and let it run until you
can feel the upper radiator hose
getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
DEX-COOL
®coolant mixture
to the coolant surge tank until
the level reaches the indicated
level mark.
5. Then replace the pressure cap. Be sure the pressure cap is
hand-tight. Check the level in the coolant surge
tank when the cooling system has
cooled down. If the coolant is not
at the proper level, repeat Steps 1
through 3 and reinstall the pressure
cap. If the coolant still is not at the
proper level when the system cools
down again, see your dealer.
Engine Overheating
The vehicle has an indicator to warn
of engine overheating.
There is an engine coolant
temperature warning light on
the vehicle's instrument panel.
See
Engine Coolant Temperature
Gauge on page 5‑15.
If the decision is made not to lift the
hood when this warning appears,
but instead get service help right
away. See Roadside Service (U.S.
and Canada) on page 13‑8 or
Roadside Service (Mexico) on
page 13‑10. If the decision is made 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
coolant is not covered by the
warranty.
Notice: If the engine catches
fire because of being driven
with no coolant, your vehicle can
be badly damaged. The costly
repairs would not be covered by
the vehicle warranty.

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.
{WARNING
.Poorly maintained and
improperly used tires are
dangerous.
.Overloading your tires can
cause overheating as a
result of too much flexing.
You could have a blowout (Continued)
WARNING (Continued)
and a serious accident.
SeeVehicle Load Limits on
page 9‑12.
.Under inflated tires pose the
same danger as overloaded
tires. The resulting crash
could cause serious injury.
Check all tires frequently to
maintain the recommended
pressure. Tire pressure
should be checked when
your tires are cold.
.Over inflated 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 or old tires can cause a
crash. If your tread is badly
worn, replace them.

Tire Pressure
Tires need the correct amount
of air pressure to operate
effectively.
Notice:Do not let anyone tell
you that under‐inflation or
over‐inflation is all right. It is
not. If your tires do not have
enough air (under‐inflation),
you can get the following:
.Tire overloading and
over-heating which could
lead to a blowout.
.Premature or
irregular wear.
.Poor handling.
.Reduced fuel economy. If your tires have too much air
(over‐inflation), you can get
the following:
.Unusual wear.
.Poor handling.
.Rough ride.
.Needless damage from
road hazards.
A vehicle-specific Tire and
Loading Information label
is attached to your vehicle.
This label shows your vehicle's
original equipment tires and the
correct inflation pressures for
your tires when they are cold.
The recommended cold tire
inflation pressure, shown on
the label, is the minimum
amount of air pressure needed
to support your vehicle's
maximum load carrying capacity. For additional information
regarding how much weight
your vehicle can carry, and an
example of the Tire and Loading
Information label, see
Vehicle
Load Limits on page 9‑12.
How you load your vehicle
affects vehicle handling and
ride comfort. Never load your
vehicle with more weight than
it was designed to carry.
When to Check
Check your tires once a month
or more. Do not forget to
check the compact spare
tire, if the vehicle has one.
The compact spare should
be at 420 kPa (60 psi).
For additional information
regarding the compact spare
tire, see Compact Spare
Tire on page 10‑93.
