5. If there is no coolant flowing outof the bleeder valve, there could
be a leak in the system. Tighten
the bleeder valve and contact
the dealer for service.
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 10‑29.
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 improper coolant
mixture, inhibitors, or additives
are used in the vehicle cooling
system, the engine could
overheat and be damaged. Too
much water in the mixture can
freeze and crack engine cooling
parts. The repairs would not be
covered by the warranty. Use only
the proper mixture of engine

5. Replace the pressure cap tightly.Check the level in the surge tank
when the system has cooled
down. If the coolant is not at the
proper level, repeat Steps 1−4,
then reinstall the pressure cap.
If the coolant is not at the proper
level when the system cools
down again, see the dealer.
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 gauge on the
instrument panel cluster. See
Engine Coolant Temperature Gauge
on page 5‑15. The vehicle may also
display a COOLANT OVER
TEMPERATURE message on the Driver Information Center (DIC). See
Engine Cooling System Messages
on page 5‑38.
If the decision is made not to lift the
hood but to get service help right
away. See
Roadside Assistance
Program (Mexico) on page 13‑7 or
Roadside Assistance Program (U.S.
and Canada) 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 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: Running the engine
without coolant may cause
damage or a fire. Vehicle damage
would not be covered by the
warranty. See Overheated Engine
Protection Operating Mode on
page 10‑30 for information on
driving to a safe place in an
emergency.
If Steam is Coming from the
Engine
{WARNING
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Turn it off
and get everyone away from the
vehicle until it cools down. Wait
until there is no sign of steam or
coolant before you open
the hood.
If you keep driving when the
vehicles engine is overheated,
the liquids in it can catch fire. You
or others could be badly burned.
Stop the engine if it overheats,
and get out of the vehicle until the
engine is cool.

WARNING (Continued)
SeeOverheated Engine
Protection Operating Mode on
page 10‑30 for information on
driving to a safe place in an
emergency.
If No Steam is Coming from
the Engine
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day
.Stops after high-speed driving
.Idles for long periods in traffic
If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off. 2. Turn the heater on to the highest
temperature and to the highest
fan speed. Open the windows as
necessary.
3. If in a traffic jam, shift to N (Neutral) while stopped. If it is
safe to do so, pull off the road,
shift to P (Park) or N (Neutral)
and let the engine idle.
If the temperature overheat gauge is
no longer in the overheat zone or an
overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle slowly
for about 10 minutes. Keep a safe
vehicle distance from the vehicle in
front. If the warning does not come
back on, continue to drive normally.
If the warning continues, pull over,
stop, and park the vehicle
right away.
If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it cools down. Also, see
“Overheated
Engine Protection Operating Mode”
next in this section.
Overheated Engine
Protection
Operating Mode
This emergency operating mode lets
the vehicle be driven to a safe
place, up to 80 km (50 mi), in an
emergency situation. If an
overheated engine condition exists
and the messages COOLANT
OVER TEMPERATURE and
REDUCED ENGINE POWER are
displayed, along with the check
engine light, an overheat protection
mode which alternates firing groups
of cylinders helps prevent engine
damage. In this mode, there is a
significant loss in power and engine
performance.
Driving extended distances in the
overheat protection mode should be
avoided.

Vehicle Care 10-31
Notice:After driving in the
overheated engine protection
operating mode, to avoid engine
damage, allow the engine to cool
before attempting any repair. The
engine oil will be severely
degraded. Repair the cause of
coolant loss, change the oil and
reset the oil life system. See
Engine Oil on page 10‑13.
Power Steering Fluid
See Engine Compartment Overview
on page 10‑8 for reservoir location.
When to Check Power Steering
Fluid
It is not necessary to regularly
check power steering fluid unless
there is a leak suspected in the
system or an unusual noise is heard. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.
How to Check Power Steering
Fluid
To check the power steering fluid:
1. Turn the ignition off and let the
engine compartment cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with a clean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the fluid level on the dipstick.
There are markings on both
sides of the dipstick.
The level should be at the FULL
COLD mark. If necessary, add only
enough fluid to bring the level up to
the mark.
When the engine compartment is
hot, the level should be at the HOT
mark. When the engine
compartment is cool, the level
should be at the FULL COLD mark.

Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have the
headlamp wiring checked right away
if the lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.
Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using the
windshield wipers.
If the overload is caused by an
electrical problem and not snow or
ice, be sure to get it fixed.
Fuses and Circuit
Breakers
The wiring circuits in the vehicle are
protected from short circuits by a
combination of J-Case fuses,
mini-fuses and circuit breakers. This
greatly reduces the chance of fires
caused by electrical problems.
Look at the silver-colored band
inside the fuse. If the band is broken
or melted, replace the fuse. Be sure
you replace a bad fuse with a new
one of the identical size and rating.
If you ever have a problem on the
road and do not have a spare fuse,
you can borrow one that has the
same amperage. Just pick some
feature of the vehicle that you can
get along without—like the radio or
cigarette lighter —and use its fuse,
if it is the correct amperage.
Replace it as soon as you can.
Vehicles with the ZR1 package have
an intercooler relay located on the
fan shroud. See your dealer. Vehicles with the ZR1 package also
have a fuel system mini-fuse. It is
located near the battery in the
battery storage compartment in the
rear of the vehicle.
Engine Compartment
Fuse Block
There is one fuse block in the
engine compartment located on the
passenger side of the vehicle. See
Engine Compartment Overview on
page 10‑8
for more information on
location.
Notice: Spilling liquid on any
electrical component on the
vehicle may damage it. Always
keep the covers on any electrical
component.
