HINTS ON CONTROLLING THE
INTERIOR CLIMATE
General Hints
Do not place objects under the front seats
as this may interfere with directing air to
the rear seats.
Remove any snow, ice or leaves from the
air intake area at the base of the
windshield.
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:
To reduce fogging of the windshield
during humid weather conditions, direct air
to the windshield air vents.
Note: Prolonged use of recirculated air may
cause the windows to fog up.
Note: Use air conditioning with recirculated
air to improve cooling performance and
efficiency.
Quickly Heating the Interior
• Select the highest blower motor speed.
• Select the highest temperature.
• Direct air to the footwell air vents.
Recommended Settings for
Heating
• Select a medium blower motor speed.
• Select the required temperature.
• Direct air to the footwell and
windshield air vents.
Quickly Cooling the Interior
• Select maximum cooling.
Note: To improve the time to reach a
comfortable temperature in hot weather,
drive with the windows open until you feel
cold air through the air vents.
Recommended Settings for
Cooling
• Select a medium blower motor speed.
• Select the required temperature.
• Direct air to the instrument panel air
vents.
• Press A/C.
Defogging the Side Windows in
Cold Weather
• Select maximum defrost.

REDUCED ENGINE
PERFORMANCE
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop
without warning. Failure to follow this
instruction could result in the loss of
control of your vehicle.
If the engine coolant temperature gauge
needle moves to the upper limit position,
the engine is overheating. See Gauges
(page 110).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on
ambient temperature, vehicle load and
terrain. The engine continues to operate
with limited power for a short period of
time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually.
1. Gradually reduce your speed and stop your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See
Engine
Coolant Check (page 285).
5. Have your vehicle checked as soon as possible. ECONOMICAL DRIVING
The following helps to improve fuel
consumption:
•
Regularly check your tire pressures and
make sure that they are inflated to the
correct pressure.
• Follow the recommended maintenance
schedule and carry out the
recommended checks.
• Plan your journey and check the traffic
before you set off.
• Avoid idling the engine in cold weather
or for extended periods. Start the
engine only when you are ready to set
off.
• Do not carry unnecessary weight in your
vehicle as extra weight wastes fuel.
• Do not add unnecessary accessories
to the exterior of your vehicle, for
example running boards. If you use a
roof rack, remember to fold it down or
remove it when not in use.
• Drive smoothly, accelerate gently and
anticipate the road ahead to avoid
heavy braking.
• Switch off all electric systems when
not in use, for example air conditioning.
Make sure that you unplug any
accessories from the auxiliary power
points when not in use.
COLD WEATHER
PRECAUTIONS
The functional operation of some
components and systems can be affected
at temperatures below approximately
-13°F (-25°C)

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.
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 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.
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.
Have an authorized dealer check and
change the transmission fluid at the
correct service interval. Your transmission
does not consume fluid. However, if the
transmission slips, shifts slowly or if you
notice a sign of leaking fluid, contact 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.
