between Fahrenheit and Celsius.
Note: You can control some of the climate
features through the touchscreen.
Accessing the Climate Control Menu Press and release the button to
access additional controls for the
front climate system. Accessing Rear Climate Controls Press and release the button to
access additional controls for the
rear climate system.
Setting the Blower Motor Speed Turn the control to adjust the volume of air
circulated in the vehicle.Setting the Temperature

of the climate control upward or downward
to set the left-hand temperature.
Note:
This control also adjusts the right-hand
side temperature when you switch off dual
zone mode.
Press the toggle button on the right-hand
side of the climate control upward or
downward to set the right-hand temperature.
Switching Auto Mode On and Off Press and release the button to
switch on automatic operation.
Repeatedly press the button to
adjust auto mode.
The system adjusts the blower motor speed,
air distribution, air conditioning operation,
and outside or recirculated air to reach and
maintain the temperature you have set.
Under high humidity conditions, the system
adjusts the blower motor speed, air
distribution and air conditioning operation
to reduce window fogging.

Note:
The system starts at the previous
setting when you switch on AUTO mode. Note:
You can also switch off dual zone
mode by pressing and holding the button for
more than two seconds.
Auto Mode Indicator Status Description
Auto Mode Indicator Status
One indicator illuminated. •The blower motor speed is reduced.
•Use this setting to minimize the amount of noise from the blower motor.
• This setting increases the time taken to cool the interior.
Two indicators illuminated. •The blower motor speed is moderate.
Three indicators illuminated. •The blower motor speed is increased.
•Use this setting to reduce the time taken to cool the interior.
• This setting increases the amount of noise from the blower motor.
Switching Defrost On and Off Press and release the button to
distribute air through the
windshield air vents and de-mister.
Air directed to the instrument panel and
footwell air vents turns off. You can also use
this setting to defog and clear the windshield
of a thin covering of ice.

Note:
In certain conditions, such as
maximum defrost, the air conditioning
compressor may continue to operate even
though you switch off the air conditioning.
Switching Maximum Air Conditioning
On and Off Press and release the button for
maximum cooling.
The left-hand and right-hand settings set to
LO, recirculated air flows through the
instrument panel air vents, air conditioning
turns on and the blower motor adjusts to the
highest speed.
Switching Recirculated Air On and Off Press and release the button to
switch between outside air and
recirculated air.
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. Note:
Recirculated air may turn off, or
prevent you from switching on, in all air flow
modes except MAX A/C to reduce the risk
of fogging. Recirculation may also turn on
and off in various air distribution control
combinations during hot weather to improve
cooling efficiency.

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.
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.
Automatic Climate Control
Note: Adjusting the settings when your
vehicle interior is extremely hot or cold is not
necessary. Automatic mode is best
recommended to maintain set temperature.

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
127).
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 383).
5. Have your vehicle checked as soon as possible.
ECONOMICAL DRIVING
Fuel economy is affected by several things
such as how you drive, the conditions you
drive under and how you maintain your
vehicle.
There are some things to keep in mind that
may improve your fuel economy:
• Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds.
• Anticipate stops; slowing down may
eliminate the need to stop. •
Combine errands and minimize
stop-and-go driving (When running
errands, go to the furthest destination
first and then work your way back home).
• Close the windows for high-speed
driving.
• Drive at reasonable speeds.
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
There are also some things you may want to
avoid doing because they reduce your fuel
economy:
• Avoid sudden or hard accelerations.
• Avoid revving the engine before turning
off the car.
• Avoid long idle periods.
• Do not warm up your vehicle on cold
mornings.
• Reduce the use of air conditioning and
heat.
• Avoid using speed control in hilly terrain.

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
440).
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.
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.
