The air conditioning system
removes moisture from the air, so
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 when
recirculation is on. When the engine
is turned off, the recirculation mode
automatically turns off and must be
re-selected when the engine is
turned on again.
This mode recirculates and helps to
quickly cool the air inside the
vehicle. It can be used to reduce the
outside air and odors that may enter
the vehicle.
The recirculation mode cannot be
used with floor, defrost, or defogging
modes. If recirculation is selected in
these modes, the indicator flashes
three times and turns off. The air
conditioning also comes on when
this mode is activated unless the
outside air temperature is less than
4 °C (40 °F). While in recirculation
mode the windows can fog when
the weather is cold and damp. To clear the fog, select either the defog
or defrost mode and increase the
fan speed.
REAR (Rear Climate Control) :
Press to turn the rear heating and
air conditioning on or off. See
Rear
Climate Control System 0189 or
Rear Climate Control System (with
Rear Seat Audio) 0190.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
1(Rear Window Defogger) :
Press to turn the rear window
defogger on or off. An indicator light
on the button comes on to show that
the rear window defogger is on. Do
not drive the vehicle until all the
windows are clear.
The defogger only works when the
vehicle is in ON/RUN. The defogger
will turn off if the vehicle is
turned off.
If equipped with heated outside
rearview mirrors, fog or frost is
cleared from the surface of the
mirror when
1is pressed.
Caution
Using a razor blade or sharp
object to clear the inside rear
window can damage the rear
window defogger. Repairs would
not be covered by the vehicle
warranty. Do not clear the inside
rear window with sharp objects.

Sensors
The solar sensor in the defrost grille
in the middle of the instrument
panel, monitors the solar heat. Do
not cover the solar sensor or the
system will not work properly.
The interior temperature sensor, on
the instrument panel to the right of
the steering column, measures the
temperature of the air inside the
vehicle.
There is also an exterior
temperature sensor behind the front
grille. This sensor reads the outside
air temperature and helps maintain
the temperature inside the vehicle.
Any cover on the front of the vehicle
could cause a false reading in the
displayed temperature.
The climate control system uses the
information from these sensors to
maintain comfort settings by
adjusting the temperature, fan

1. View displayed by thecamera.
2. Corner of the rear bumper.
When the System Does Not
Seem To Work Properly
The RVC system might not work
properly or display a clear image if:
. It is dark.
. The sun or the beam of
headlamps is shining directly
into the camera lens.
. Ice, snow, mud, or anything else
builds up on the camera lens.
Clean the lens, rinse it with
water, and wipe it with a soft
cloth. .
The back of the vehicle is in an
accident. The position and
mounting angle of the camera
can change or the camera can
be affected. Be sure to have the
camera and its position and
mounting angle checked at your
dealer.
. There are extreme temperature
changes.
Parking Assist
If available, the Rear Parking Assist
(RPA) system assists the driver with
parking and avoiding objects while
in R (Reverse). RPA operates at
speeds less than 8 km/h (5 mph).
The sensors on the rear bumper are
used to detect objects up to
2.5 m (8 ft) behind the vehicle, and
at least 25 cm (10 in) off the ground
and below liftgate level. Detection
distances may be less during
warmer or humid weather.
{Warning
The parking assist system does
not detect children, pedestrians,
bicyclists, animals, or objects
below the bumper or that are too
close or too far from the vehicle.
It is not available at speeds
greater than 8 km/h (5 mph). To
prevent injury, death, or vehicle
damage, even with parking assist,
always check the area around the
vehicle and check all mirrors
before backing.
How the System Works
RPA comes on automatically when
the shift lever is moved into
R (Reverse). A single beep sounds
to indicate the system is working.
An obstacle is indicated by audible
beeps. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in) the beeping is
continuous for five seconds.

Driving and Operating 229
How the System Works
The LDW camera sensor is on the
windshield ahead of the rearview
mirror.
To turn LDW on and off, press
@on
the center stack, forward of the shift
lever. The control indicator will light
when LDW is on.
When LDW is on,@is green if
LDW is available to warn of a lane
departure. If the vehicle crosses a
detected lane marking without using
the turn signal in that direction,
@
changes to amber and flashes.
Additionally, there will be three
beeps on the right or left, depending
on the lane departure direction.
When the System Does Not
Seem to Work Properly
The system may not detect lanes as
well when there are:
. Close vehicles ahead.
. Sudden lighting changes, such
as when driving through tunnels.
. Banked roads.
If the LDW system is not functioning
properly when lane markings are
clearly visible, cleaning the
windshield may help.
LDW alerts may occur due to tar
marks, shadows, cracks in the road,
temporary or construction lane
markings, or other road
imperfections. This is normal system
operation; the vehicle does not need
service. Turn LDW off if these
conditions continue.
Fuel
Use of the recommended fuel is an
important part of the proper
maintenance of this vehicle. When
driving in the U.S. and Canada, to
help keep the engine clean and
maintain optimum vehicle
performance, we recommend using
TOP TIER Detergent Gasolines.
See www.toptiergas.com for a list of
TOP TIER Detergent Gasolines.
Use regular unleaded gasoline
meeting ASTM specification D4814
with a posted octane rating of 87 or
higher. Do not use gasoline with an
