ENGINE COOLING FAN

48% to 50%, which equates to a freeze

point between -30°F (-34°C) and -34°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.

WARNING

Keep your hands and clothing clear

of the engine cooling fan.

Under certain conditions, the engine

cooling fan may continue to run for several

minutes after you switch your vehicle off.

Adding Coolant

WARNING

ENGINE COOLANT CHECK

Never remove the coolant reservoir

cap when the engine is running or

hot.

WARNINGS

Do not add engine coolant when the

engine is hot. Steam and scalding

system can burn you badly. Also, spilling

coolant on hot engine parts can burn you.

Do not put engine coolant in the

windshield washer fluid container. If

sprayed on the windshield, engine

coolant could make it difficult to see

through the windshield.

To reduce the risk of personal injury,

make sure the engine is cool before

unscrewing the coolant pressure

relief cap. The cooling system is under

pressure. Steam and hot liquid can come

out forcefully when you loosen the cap

slightly.

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.

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 275). 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 may

not be covered by the vehicle Warranty.

Do not add coolant further than the

MAX mark.

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 409).

Note: Make sure that the coolant level is

between the MIN and MAX marks on the

coolant reservoir.

Note: If prediluted coolant is not available,

use the approved concentrated coolant

diluting it to 50/50 with distilled water. See

Capacities and Specifications (page 275).

Using water that has not been deionised

may contribute to deposit formation,

corrosion and plugging of the small cooling

system passageways.

Note: Coolant expands when it is hot. The

level may extend beyond the MAX mark.

large amount of water without coolant in

order to reach a vehicle service location.

Water alone, without coolant, can cause

drained and refilled with prediluted coolant

approved to the correct specification. See

immediately.

4. Replace the coolant reservoir cap, turn

it clockwise until you feel a strong

resistance.

5. Check the coolant level in the coolant

reservoir the next few times you drive

your vehicle. If necessary, add enough

prediluted engine coolant to bring the

coolant level to the correct level.

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.

Do not add extra inhibitors or additives to

the coolant. These can be harmful and

compromise the corrosion protection of

the coolant.

Recycled Coolant

We do not recommend the use of recycled

coolant as an approved recycling process

is not yet available.

Dispose of used engine coolant in an

appropriate manner. Follow your

community’s regulations and standards

for recycling and disposing of automotive

fluids.

Note: During normal vehicle operation, the

coolant may change color from orange to

pink or light red. As long as the coolant is

clear and uncontaminated, this color change

does not indicate the coolant has degraded

nor does it require the coolant to be drained,

the system to be flushed, or the coolant to

be replaced.

Severe Climates

If you drive in extremely cold climates:

•

It may be necessary to increase the

coolant concentration above 50%.

•

A coolant concentration of 60%

provides improved freeze point

protection. Coolant concentrations

above 60% decrease the overheat

protection characteristics of the

coolant and may cause engine

damage.

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.

When this occurs, your vehicle still

concentration to 40%.

•

Coolant concentrations below 40%

decrease the freeze and corrosion

protection characteristics of the

coolant and may cause engine

damage.

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.

Vehicles driven year-round in non-extreme

climates should use prediluted coolant for

optimum cooling system and engine

protection.

When Fail-Safe Mode Is Activated

WARNINGS

Coolant Change

At specific mileage intervals, as listed in

the scheduled maintenance information,

the coolant should be changed. Add

prediluted coolant approved to the correct

specification. See Capacities and

Specifications (page 269).

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.

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.

Never remove the coolant reservoir

cap when the engine is running or

hot.

How Fail-Safe Cooling Works

If the engine begins to overheat, the

coolant temperature gauge moves toward

the red zone:

vehicle with caution. Your vehicle does not

maintain high-speed operation and the

engine may operate poorly.

You may notice a reduction in vehicle

speed caused by reduced engine power.

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 pull off the road. You can continue to

drive your vehicle.

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

display, do the following:

1. Pull off the road as soon as safely

possible and shift the transmission into

park (P).

Remember that the engine is capable of

automatically shutting down to prevent

engine damage. In this situation:

1. 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 a short

period 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.

several minutes, if the temperature

does not drop, follow the remaining

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.
