Engine Coolant Temperature
Gauge 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.
At normal operating temperature, the
engine coolant temperature will be in the
middle range of the gauge. If the engine
coolant temperature exceeds the normal
range, the gauge will be highlighted. Stop
your vehicle as soon as safely possible,
switch off the engine and let it cool.
Engine Oil Temperature Gauge
If the engine oil temperature exceeds the
normal range, the engine is overheating.
Reduce engine speed as soon as safely
possible to allow the engine to cool. If you
continue to operate the engine at high
engine speeds, the engine speed reduces
automatically to prevent engine damage.
Engine Oil Pressure Gauge
Oil pressure varies with engine speed. The
pressure rises as engine speed rises and
drops as engine speed drops. If the pressure drops below the normal
range of the gauge, a warning lamp
illuminates and a message appears in the
information display. Stop your vehicle as
soon as it is safe to do so and switch the
engine off. Check the engine oil level.
Gauge Mode
On the right side of the instrument cluster,
you can configure which gauges are
displayed.

The air currently in the passenger
compartment recirculates. This may
reduce the time needed to cool the interior,
when used with A/C, and reduce unwanted
odors from entering your vehicle.
HINTS ON CONTROLLING THE
INTERIOR CLIMATE
General Hints
Note:
Prolonged use of recirculated air may
cause the windows to fog up.
Note: You may feel a small amount of air
from the footwell air vents regardless of the
air distribution setting.
Note: To reduce humidity build-up inside
your vehicle, do not drive with the system
switched off or with recirculated air always
switched on.
Note: Do not place objects under the front
seats as this may interfere with the airflow
to the rear seats.
Note: Remove any snow, ice or leaves from
the air intake area at the base of the
windshield.
Automatic Climate Control
Note: Adjusting the settings when your
vehicle interior is extremely hot or cold is
not necessary.
Note: The system adjusts to heat or cool
the interior to the temperature you select
as quickly as possible.
Note: For the system to function efficiently,
the instrument panel and side air vents
should be fully open.
Note: If you select AUTO during cold
outside temperatures, the system directs
air flow to the windshield and side window
air vents. In addition, the blower motor may
run at a slower speed until the engine warms
up. Note:
If you select
AUTO during hot
temperatures and the inside of the vehicle
is hot, the system uses recirculated air to
maximize interior cooling. Blower motor
speed may also reduce until the air cools.

Maintain coolant concentration within
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.
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.
Note: Automotive fluids are not
interchangeable. Do not use coolant or
windshield washer fluid outside of its
specified function and vehicle location.
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 meeting the correct specification
to avoid plugging the small passageways
in the engine cooling system. See
Capacities and Specifications
(page
205). 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:
Coolants marketed for all makes and
models may not meet 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
MIN
mark, add prediluted coolant immediately.
Only check the coolant level or add coolant
when the system is cold.
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 meeting the correct specification. See
Capacities
and Specifications (page 205).
3. Add enough prediluted coolant to reach the correct level.
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.
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.

Note:
In case of emergency, you can add a
large amount of water without coolant in
order to reach a vehicle service location.
Water alone, without coolant, can cause
engine damage from corrosion, overheating
or freezing.
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:
•
It may be necessary to decrease the
coolant concentration to 40%.
• A coolant concentration of 40%
provides improved overheat
protection. Coolant concentrations
below 40% decrease the freeze 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 meeting the correct
specification. See Capacities and
Specifications (page 205).
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.
