ENGINE COOLANT CHECK

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 put coolant in the

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

WARNING: 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.

WARNING: 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 579).

Note: Make sure that the coolant level is
between the MIN and the MAX marks on
the coolant reservoir.

Note:  Coolant expands when it is hot.  The
level may extend beyond the MAX mark.

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.

400

Maintenance

Note:  Automotive fluids are not
interchangeable.  Take care not to put
engine coolant in the windshield washer fluid
reservoir or windshield washer fluid in the
engine coolant reservoir.

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 461).  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.

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 461).
Using water that has not been deionised
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways.

Note:  Coolants marketed for all makes and
models may not be approved to our
specifications and may cause damage to
the cooling system.  Resulting component
damage may not be covered by the vehicle
Warranty.

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

To top up the coolant level do the following:

1. Unscrew the cap slowly. Any pressure

escapes as you unscrew the cap.

2. Add prediluted coolant approved to the

correct specification.  See Capacities and
Specifications (page 461).

3. Add enough prediluted coolant to reach

the correct level.

4. Replace the coolant reservoir cap. Turn

the cap clockwise until it contacts the
hard stop.

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.

In case of emergency, you can add a large
amount of water without engine coolant in
order to reach a vehicle service location. In
this instance, qualified personnel:

1. Must drain the cooling system.

2. Chemically clean the coolant system.

3. Refill with engine coolant as soon as

possible.

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

401

Maintenance

Do not use the following as a coolant
substitute:
•

Alcohol.

•

Methanol.

•

Brine.

•

Any coolant mixed with alcohol or
methanol antifreeze.

Alcohol and other liquids can cause engine
damage from overheating or freezing.

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.

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 you drive in extremely hot climates:
•

You can decrease the coolant
concentration to 40%.

•

A coolant concentration of 40% provides
improved overheat protection.

•

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

Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection.

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
461).

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.

402

Maintenance

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 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

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.

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 may
operate poorly.

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.

403

Maintenance

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.

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:

1. 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.

AUTOMATIC TRANSMISSION
FLUID CHECK

The automatic transmission does not have
a transmission fluid dipstick.

The automatic transmission does not
consume fluid. However, the fluid level
should be checked if the transmission is not
working properly, for example if the
transmission slips or shifts slowly or if you
notice some sign of fluid leakage.

404

Maintenance

Note: Transmission fluid should be checked
by an authorized dealer. If required, fluid
should be added by an authorized dealer.

Do not use supplemental transmission fluid
additives, treatments or cleaning agents. The
use of these materials may affect
transmission operation and result in damage
to internal transmission components.

BRAKE FLUID CHECK

WARNING: Do not use any fluid other

than the recommended brake fluid as this
will reduce brake efficiency. Use of
incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death.

WARNING: Only use brake fluid from

a sealed container. Contamination with dirt,
water, petroleum products or other
materials may result in brake system
damage or failure. Failure to adhere to this
warning could result in the loss of vehicle
control, serious personal injury or death.

WARNING: Do not allow the fluid to

touch your skin or eyes. If this happens,
rinse the affected areas immediately with
plenty of water and contact your physician.

WARNING: The brake system could

be affected if the brake fluid level is below
the MIN mark or above the MAX mark on
the brake fluid reservoir.

E170684

1. Park your vehicle on a level surface.

2. Look at the brake fluid reservoir to see

where the brake fluid level is relative to
the MIN and the MAX marks on the
reservoir.

Note: If the brake fluid level is between the
MIN and the MAX marks on the reservoir, it
is acceptable.

405

Maintenance

Note: If the brake fluid level is below the MIN
mark or above the MAX mark, have your
vehicle checked as soon as possible.

Note: To avoid fluid contamination, the
reservoir cap must remain in place and fully
tight, unless you are adding fluid.

Only use fluid that meets our specifications.
See Capacities and Specifications (page
461).

Brake Fluid Service Interval

Brake fluid absorbs water over time which
degrades the effectiveness of the brake fluid.
Change the brake fluid at the specified
intervals to prevent degraded braking
performance.

For detailed interval information, see
Scheduled Maintenance in your Owner's
Manual or your local maintenance guide.

POWER STEERING FLUID CHECK

Your vehicle is equipped with an electric
power steering (EPS) system. There is no
fluid reservoir to check or fill.

CHANGING THE 12V BATTERY

WARNING: Batteries normally

produce explosive gases which can cause
personal injury. Therefore, do not allow
flames, sparks or lighted substances to
come near the battery. When working near
the battery, always shield your face and
protect your eyes. Always provide correct
ventilation.

WARNING: When lifting a

plastic-cased battery, excessive pressure
on the end walls could cause acid to flow
through the vent caps, resulting in personal
injury and damage to the vehicle or battery.
Lift the battery with a battery carrier or with
your hands on opposite corners.

WARNING: Keep batteries out of

reach of children. Batteries contain sulfuric
acid. Avoid contact with skin, eyes or
clothing. Shield your eyes when working
near the battery to protect against possible
splashing of acid solution. In case of acid
contact with skin or eyes, flush immediately
with water for a minimum of 15 minutes and
get prompt medical attention. If acid is
swallowed, call a physician immediately.

WARNING: Battery posts, terminals

and related accessories contain lead and
lead compounds, chemicals known to the
State of California to cause cancer and
reproductive harm. Wash your hands after
handling.

406

Maintenance

WARNING: This vehicle may have

more than one battery. Removing the
battery cables from only one battery does
not disconnect your vehicle electrical
system. Make sure you disconnect the
battery cables from all batteries when
disconnecting power. Failure to do so may
cause serious personal injury or property
damage.

WARNING: For vehicles with

Auto-Start-Stop the battery requirement is
different. You must replace the battery with
one of exactly the same specification.

The battery is in the engine compartment. 
See Under Hood Overview (page 393).

Your vehicle has a maintenance-free battery. 
It does not require additional water during
service.

If the vehicle battery has a cover and vent
hose, make sure you correctly install it after
cleaning or replacing the battery.

For longer, trouble-free operation, keep the
top of the battery clean and dry and the
battery cables tightly fastened to the battery
terminals. If any corrosion is present on the
battery or terminals, remove the cables from
the terminals and clean with a wire brush. 
You can neutralize the acid with a solution
of baking soda and water.

We recommend that you disconnect the
negative battery cable terminal from the
battery if you plan to store your vehicle for
an extended period.

Note: If you only disconnect the negative
battery cable terminal, make sure it is
isolated or placed away from the battery
terminal to avoid unintended connection or
arcing.

If you replace the battery make sure it
matches the electrical requirements of your
vehicle.

If you disconnect or replace the battery and
your vehicle has an automatic transmission,
it must relearn its adaptive strategy. Because
of this, the transmission may shift firmly when
first driven. This is normal operation while
the transmission fully updates its operation
to optimum shift feel.

Battery Sensor Reset

When you install a new battery, reset the
battery sensor by doing the following:

1. Switch the ignition on, and leave the

engine off.

Note: Complete Steps 2 and 3 within 10
seconds.

2. Flash the high beam headlamps five

times, ending with the high beams off.

3. Press and release the brake pedal three

times.

The battery warning lamp flashes three times
to confirm that the reset is successful.
