windshield of fog or frost more
quickly. Air is directed to the
windshield.
For best results, clear all snow and
ice from windshield before
defrosting.
#(Air Conditioning): Press to
turn the air conditioning system on
or off. If the fan is turned off or the
outside temperature falls below
freezing, the air conditioner will
not run.
Pressing this button cancels
automatic air conditioning and turns
off the air conditioner. Press AUTO
to return to automatic operation and
the air conditioner runs
automatically as needed. When the
indicator light is on, the air
conditioner runs automatically to
cool the air inside the vehicle or to
dry the air needed to defog the
windshield faster.
>//(Recirculation/Auto
Recirculation): Press to change to
automatic control of air recirculation
inside the vehicle. When the auto
recirculation indicator light is on, the
air is automatically recirculated as
needed to help quickly cool the air
inside the vehicle.
In auto recirculation control, the Air
Quality Control system may operate
when pollution is detected. To adjust
the sensitivity of the Air Quality
Control, see Climate and Air Quality
under Vehicle Personalization
on
page 4‑38.
When the
>indicator light is on, air
is recirculated inside the vehicle.
If both indicator lights are off,
outside air will flow into the vehicle.
Press AUTO or
/to return to
automatic operation. Auto Defog:
The climate control
system may have a sensor to
automatically detect high humidity
inside the vehicle. When high
humidity is detected, the climate
control system may adjust to
outside air supply and turn on the
air conditioner. The fan speed may
slightly increase to help prevent
fogging. If the climate control
system does not detect possible
window fogging, it returns to normal
operation. To turn Auto Defog off or
on, see Climate and Air Quality
under Vehicle Personalization
on
page 4‑38.

8-18 Driving and Operating
Ignition Positions (Key
Access)
The ignition switch has four different
positions.
Notice:Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct
key, make sure it is all the way in,
and turn it only with your hand.
If the key cannot be turned by
hand, see your dealer/retailer. To shift out of P (Park), turn the
ignition to ON/RUN and apply the
brake pedal.
A (LOCK/OFF):
This is the only
position from which the key can be
removed. This locks the ignition and
automatic transmission.
The shift lever must be in P (Park)
to turn the ignition switch to the
LOCK/OFF position.
The ignition switch can bind in the
LOCK/OFF position with the wheels
turned off center. If this happens,
move the steering wheel from right
to left while turning the key to ACC/
ACCESSORY. If this does not work,
then the vehicle needs service.
B (ACC/ACCESSORY) : This
position provides power to some of
the electrical accessories. It unlocks
the ignition. The transmission is
also unlocked in this position on
automatic transmission vehicles.
To move the key from ACC/
ACCESSORY to LOCK/OFF, the
shift lever must be in P (Park). C (ON/RUN):
The ignition switch
stays in this position when the
engine is running. This position can
be used to operate the electrical
accessories, including the
ventilation fan and 12 volt power
outlet, as well as to display some
warning and indicator lights.
The battery could be drained if the
key is left in the ACC/ACCESSORY
or ON/RUN position with the engine
off. The vehicle might not restart if
the battery is allowed to drain for an
extended period of time.
D (START) : This position starts
the engine. When the engine starts,
release the key. The ignition switch
will return to ON/RUN for normal
driving.
A warning tone sounds when the
driver door is opened when the
ignition is still in ACC/ACCESSORY
and the key is in the ignition.

Driving and Operating 8-41
{WARNING
The Ultrasonic Rear Parking
Assist (URPA) system does not
replace driver vision. It cannot
detect:
.objects that are below the
bumper, underneath the
vehicle, or if they are too
close or far from the vehicle
.children, pedestrians,
bicyclists, or pets.
If you do not use proper care
before and while backing; vehicle
damage, injury, or death could
occur. Even with URPA, always
check behind the vehicle before
backing up. While backing, be
sure to look for objects and check
the vehicle's mirrors. The display is located in the
headliner.
URPA uses three color-coded lights
to provide distance and system
information.
How the System Works
URPA comes on automatically and
the display briefly illuminates to
indicate the system is working when
the shift lever is moved into
R (Reverse). If the vehicle is traveling faster then
8 km/h (5 mph) in reverse, the red
light on the rear display flashes.
Objects must be at least 20 cm
(8 in.) off the ground, below liftgate
level, and within 2.5 m (8 ft.) from
the rear bumper to be detected. The
distance may be less during warmer
or humid weather.
A single beep sounds the first time
an object is detected between 0.6 m
(23 in.) and 2.5 m (8 ft.) away.
Beeping occurs continuously when
the vehicle is 0.6 m (23 in.) or closer
to an object.

8-42 Driving and Operating
The following describes how the URPA display lights appear as the vehicle
gets closer to a detected object:Description Metric Englishamber light 2.5 m 8 ft.
amber/amber lights 1.0 m 40 in.
amber/amber/red lights and continuous beeping for five seconds 0.6 m 23 in.
amber/amber/red lights flashing and continuous beeping for five seconds 0.3 m 1 ft.
PARK ASSIST OFF displays on the
Driver Information Center (DIC) to
indicate that URPA is off, see Driver
Information Center (DIC)
on
page 4‑25for more information.
Turning the System On and Off
The URPA system can be turned on
and off using the park assist button
located next to the shift lever.
The park assist button lights up
when the system is on and turns off
when it has been disabled.
URPA defaults to the on setting
each time the vehicle is started.
When the System Does Not
Seem to Work Properly
If the URPA system does not
activate due to a temporary
condition, the message PARK
ASSIST OFF displays on the DIC
and a red light is shown on the rear
URPA display when the shift lever is
moved into R (Reverse). This can
occur under the following
conditions:
.The ultrasonic sensors are not
clean. Keep the vehicle's rear
bumper free of mud, dirt, snow,
ice and slush. For cleaning
instructions, see Exterior Care
on page 9‑82.
.A trailer was attached to the
vehicle, or an object was
hanging out of the trunk during
the last drive cycle, a red light
may come on in the rear display.
Once the attached object is
removed, URPA will return to
normal operation.

9-76 Vehicle Care
1. Check the other vehicle. It musthave a 12-volt battery with a
negative ground system.
Notice: If the other vehicle's
system is not a 12-volt system
with a negative ground, both
vehicles can be damaged. Only
use vehicles with 12-volt systems
with negative grounds to jump
start your vehicle. 2. Position the two vehicles so that
they are not touching.
3. Set the parking brake firmly and put the shift lever in P (Park).
See Shifting Into Park
on
page 8‑23. Notice:
If you leave the radio or
other accessories on during the
jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off the
radio and other accessories when
jump starting the vehicle.
4. Turn the ignition to LOCK/OFF
and switch off all lights and
accessories in both vehicles,
except the hazard warning
flashers if needed.
{WARNING
An electric fan can start up even
when the engine is not running
and can injure you. Keep hands,
clothing and tools away from any
underhood electric fan.
