will be heard when the engine
has overheated. Stop and turn the
engine off immediately to avoid
severe engine damage. See Engine
Overheating on page 10‑34.
ENGINE PROTECTION
REDUCE ENGINE RPM
This message displays if the
engine oil temperature exceeds
160°C (320°F). Check the engine
coolant temperature and engine oil
level. If the engine is too hot, see
Engine Overheating on page 10‑34.
The vehicle may need service, so
see your dealer.
You can monitor the oil temperature
with the gauges button on the DIC.
See Driver Information Center (DIC)
on page 5‑25.
Multiple chimes sound when
this message is displayed. This

active until the issue is resolved.
HOT ENGINE AIR
CONDITIONING OFF
This message displays when
the engine coolant becomes
hotter than the normal operating
temperature. To avoid added strain
on a hot engine, the air conditioning
compressor is automatically turned
off. When the coolant temperature
returns to normal, the A/C operation
automatically resumes. You can
continue to drive the vehicle. If this
message continues to appear, have
the system repaired by your dealer
as soon as possible to avoid
compressor damage.
Engine Oil Messages
CHANGE ENGINE OIL
This message displays when the
life of the engine oil has expired.
See Scheduled Maintenance on
page 11‑2. After an oil change, the engine oil life system must be reset.
See

Manual Operation
Driver Power/Temperature:Press
the driver temperature knob to
turn the climate control system
off. This is the only setting that
completely shuts off the fan.
The digital display shows only
the outside temperature. The driver
and the passenger set temperature
and the air intake mode can still be
adjusted when the climate control
is off.
Passenger Power/Temperature:
Press the passenger temperature
knob to turn the passenger's climate
control system on or off. Turn the
knob to increase or decrease the
temperature for the passenger. If the
passenger's climate control system
is off, the driver's temperature knob
will control the temperature for the
entire vehicle.
x 9 w(Fan): Press to increase
or decrease the fan speed. The fan
speed setting will appear in the
display. Pressing the arrows will delete
AUTO from the digital display.
The fan graphics with the fan speed
bars will be shown. The AUTO
button must be pressed to return
to the automatic fan control.
If the airflow seems low when the
fan speed is at the highest setting,
the passenger compartment air
filter may need to be replaced. For
more information, see
Passenger
Compartment Air Filter on page 8‑7.
N(Air Delivery Mode Control):
Press this button to manually lock in
the current air delivery setting and
to stop the automatic mode control.
Pressing
Ndeletes AUTO from
the digital display and the mode
graphics will be shown. To change
the setting, press
Nagain. The
AUTO button must be pressed to
return to the automatic mode
selection. To change the current mode, select
one of the following:
H(Vent):
Air is directed to the
instrument panel outlets, with some
air directed to the floor outlets.
%(Bi-Level): Air is divided
between the instrument panel and
floor outlets.
6(Floor): Air is directed to the
floor outlets, with some air directed
to the windshield and side window
defogger outlets.
-(Floor/Defog): This mode clears
the windows of fog or moisture.
Air is directed to the windshield
and the floor outlets, with a
small amount to the side window
outlets. In this mode, the system
automatically turns off the
recirculation and runs the
air-conditioning compressor
unless the outside temperature
is at or below freezing. The
recirculation mode cannot be
selected while in the defog mode.

8-4 Climate Controls
1(Defrost):This mode clears the
windows of fog or frost more quickly.
Air is directed to the windshield,
with a small amount directed to the
side window outlets. The indicator
light comes on and the digital
display will show the defrost mode
symbol and fan speed when the
front defrost mode is being used. In
this mode, the system automatically
turns off the recirculation and runs
the air-conditioning compressor,
unless the outside temperature is
at or below freezing. Recirculation
cannot be selected while in the
defrost mode. Pressing
1again
will return the system to the last
operating mode.
For severe ice conditions, turn
the driver's temperature knob to
32°C (90°F) while in defrost mode.
Do not drive the vehicle until all the
windows are clear.
^(Air Conditioning Off): Press
to turn the air conditioning
compressor off. Press AUTO to
return to automatic operation.
When in AUTO, the air conditioning
compressor comes on automatically,
as needed.
Air conditioning does not
operate at temperatures below
about 2°C to 4°C (35°F to 40°F).
In temperatures above 4°C (40°F),
the air conditioning cannot be
turned off in defrost and defog,
as it helps to remove moisture
from the vehicle. It also helps to
keep the windows clear.
You may notice a slight change
in engine performance when the
air-conditioning compressor shuts
off and turns on again. This is
normal. The system is designed to
make adjustments to help with fuel
economy while still maintaining the
selected temperature. On hot days, open the windows to
let hot inside air escape; then close
them. This helps to reduce the time
it takes for the vehicle to cool down.
It also helps the system to operate
more efficiently.
For quick cool down on hot
days press the AUTO button and
adjust the temperature to a cool,
comfortable setting. To achieve
maximum cool down, do the
following:
1. Select
Hmode.
2. Press
?.
3. Select the a/c on.
4. Select the coolest temperature.
5. Select the highest fan speed.

Climate Controls 8-5
Using these settings together for
long periods of time may cause
the air inside of your vehicle to
become too dry. To prevent this
from happening, after the air in
the vehicle has cooled, turn the
recirculation mode off.
The air conditioning system
removes moisture from the air,
so a small amount of water might
drip under the vehicle while idling
or after turning off the engine.
This is normal.
?(Recirculation):Press to
turn the recirculation mode on or off.
An indicator light comes on to show
that recirculation is on. This mode
prevents outside air from entering
your vehicle. It can be used to
prevent outside air and odors from
entering your vehicle and to help
cool the air inside your vehicle more
quickly. Recirculation mode is not
available in defrost or defog mode.
Sensors
The solar sensor on the vehicle
monitors the solar heat and
uses the information to maintain
the selected temperature when
operating in AUTO mode by
automatically adjusting the
temperature, fan speed and air
delivery system. The system
may also supply cooler air to the
side of the vehicle facing the sun.
The recirculation mode will also
be activated, as necessary. Do not
cover the solar sensor located on
the top of the instrument panel near
the windshield or the system will
not work properly.
There is also a sensor located
behind the front bumper.
This sensor reads the outside
air temperature and helps to
maintain the temperature inside
the vehicle. Any cover on the front
of the vehicle could give a false
reading in the temperature. If the outside temperature goes up,
the displayed temperature will not
change until:
.The vehicle's speed is above
19 km/h (12 mph) for 5 minutes.
.The vehicle's speed is above
52 km/h (32 mph) for
2.5 minutes.
These delays prevent false
readings. If the temperature goes
down, the outside temperature
will be shown when you start the
vehicle. If it has been turned off
for less than three hours, the
temperature will be recalled from
the previous vehicle operation.
There is also an inside temperature
sensor located to the left of the
ignition switch. The automatic
climate control system uses this
sensor to receive information, so
if you block or cover it, the system
will not function properly.
