Maintenance

CHECKING THE COOLANT

When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See

Scheduled

Maintenance

(page 622).

Note:

Make sure that the coolant level is

between the minimum and maximum marks
on the coolant reservoir.

Note:

Coolant expands when it is hot. The

level may extend beyond the

MAX

mark.

If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.

Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between -29°F (-34°C) and -35°F
(-37°C). Coolant concentration should be
checked using a refractometer. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration.

Adding Coolant

WARNING:

Do not remove the

coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury.

WARNING:

Do not add engine

coolant when the engine is on or the
cooling system is hot. Failure to follow
this instruction could result in personal
injury.

WARNING:

Do not add coolant

further than the

MAX

mark.

WARNING:

Do not put coolant in

the windshield washer reservoir. If
sprayed on the windshield, coolant could
make it difficult to see through the
windshield.

Note:

Do not use stop leak pellets, cooling

system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.

Note:

Automotive fluids are not

interchangeable.

It is very important to use prediluted
coolant approved to the correct
specification in order to avoid plugging the
small passageways in the engine cooling
system. See

Capacities and

Specifications

(page 467). Do not mix

different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine
or cooling system components and could
void the vehicle Warranty.

Note:

If prediluted coolant is not available,

use the approved concentrated coolant
diluting it to 50/50 with deionized or
distilled water. See

Capacities and

Specifications

(page 467). Using water that

has not been deionized may contribute to
deposit formation, corrosion and plugging
of the small cooling system passageways.

To top up the coolant level do the
following:

Unscrew the cap slowly. Any pressure
escapes as you unscrew the cap.

2. Add enough prediluted coolant to

reach the correct level.

Note:

We do not recommend the use of

recycled coolant.

402

Maintenance

3. Replace the coolant reservoir cap. Turn

the cap clockwise until it contacts the
hard stop.

4. Check the coolant level in the coolant

reservoir the next few times you drive
your vehicle. If necessary, repeat step
2.

If you have to add more than 1.1 qt (1 L) of
engine coolant per month, have your
vehicle checked as soon as possible.
Operating an engine with a low level of
coolant can result in engine overheating
and possible engine damage.

In case of emergency, you can add a large
amount of water without engine coolant
in order to reach a vehicle service location.
Service your vehicle as soon as possible.

Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.

Do not use the following as a coolant
substitute, as they can cause engine
damage from overheating or freezing:
•

Alcohol.

•

Methanol.

•

Brine.

•

Any coolant mixed with alcohol or
methanol antifreeze.

Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of
the coolant.

Severe Climates

If you drive in extremely cold climates, you
may need to increase the coolant
concentration above 50%.

Note:

A coolant concentration of 60%

provides improved freeze point protection.
Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and could
cause engine damage.

If you drive in extremely hot climates, you
may need to decrease the coolant
concentration to 40%.

Note:

A coolant concentration of 40%

provides improved overheat protection.
Coolant concentrations below 40%
decrease the overheat and corrosion
protection characteristics of the coolant and
could cause engine damage.

Coolant Change

Change the coolant at specific mileage
intervals. Refer to the scheduled
maintenance information. See

Normal

Scheduled Maintenance

(page 628).

Note:

Dispose of used coolant in the

appropriate manner.

Follow your community's regulations and
standards for recycling and disposing of
automotive fluids.

Fail-Safe Cooling

Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient
temperature, vehicle load and terrain.

How Fail-Safe Cooling Works

If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:

A warning lamp illuminates and
a message may appear in the
information display.

If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating
cylinder operation. Each disabled cylinder
acts as an air pump and cools the engine.

403

Maintenance

When this occurs, your vehicle still
operates, however:
•

Engine power is limited.

•

The air conditioning system turns off.

Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.

When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.

When Fail-Safe Mode Is Activated

WARNING:

Fail-safe mode is for

use during emergencies only. Operate
your vehicle in fail-safe mode only as
long as necessary to bring your vehicle
to rest in a safe location and seek
immediate repairs. When in fail-safe
mode, your vehicle will have limited
power, will not be able to maintain
high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury.

WARNING:

Do not remove the

Your vehicle has limited engine power
when in the fail-safe mode, drive your
vehicle with caution. Your vehicle does not
maintain high-speed operation and the
engine could operate poorly.

Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:

Pull off the road as soon as safely
possible and switch the engine off.

2. If you are a member of a roadside

assistance program, we recommend
that you contact your roadside
assistance service provider.

3. If this is not possible, wait for a short

period of time for the engine to cool.

4. Check the coolant level. If the coolant

level is at or below the minimum mark,
add prediluted coolant immediately.

5. When the engine temperature cools,

you can re-start the engine. Have your
vehicle checked as soon as possible to
minimize engine damage.

Note:

Driving your vehicle without repair

increases the chance of engine damage.

Engine Coolant Temperature
Management

(If Equipped)

WARNING:

To reduce the risk of

crash and injury, be prepared that the
vehicle speed may reduce and the
vehicle may not be able to accelerate
with full power until the coolant
temperature reduces.

If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long
or steep grade in high ambient
temperatures.

At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display.

404

Maintenance

You may notice a reduction in vehicle
speed caused by reduced engine power in
order to manage the engine coolant
temperature. Your vehicle may enter this
mode if certain high-temperature and
high-load conditions take place. The
amount of speed reduction depends on
vehicle loading, grade and ambient
temperature. If this occurs, there is no
need to stop your vehicle. You can
continue to drive.

The air conditioning may automatically
turn on and off during severe operating
conditions to protect the engine from
overheating. When the coolant
temperature decreases to the normal
operating temperature, the air conditioning
turns on.

If the coolant temperature gauge moves
fully into the red zone, or if the coolant
temperature warning or service engine
soon messages appear in your information
display, do the following:

Stop your vehicle as soon as it is safe
to do so. Fully apply the parking brake,
shift into park (P) or neutral (N).

2. Leave the engine running until the

coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after
several minutes, follow the remaining
steps.

3. Switch the engine off and wait for it to

cool. Check the coolant level.

4. If the coolant level is at or below the

minimum mark, add prediluted coolant
immediately.

5. If the coolant level is normal, restart

the engine and continue.
