Manual Liftgate Operation
{WARNING
Exhaust gases can enter the
vehicle if it is driven with the
liftgate, trunk/hatch open, or
with any objects that pass
through the seal between the
body and the trunk/hatch or
liftgate. Engine exhaust contains
carbon monoxide (CO) which
cannot be seen or smelled.
It can cause unconsciousness
and even death.
If the vehicle must be driven with
the liftgate, or trunk/hatch open:
.Close all of the windows.
.Fully open the air outlets
on or under the instrument
panel.(Continued)
WARNING (Continued)
.Adjust the Climate Control
system to a setting that
brings in only outside air
and set the fan speed to the
highest setting. See Climate
Control System in the Index.
.If the vehicle is equipped with
a power liftgate, disable the
power liftgate function.
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑24.
To unlock the liftgate, use the
power door lock switch or press
the door unlock button on the
RKE transmitter twice. See Remote
Keyless Entry (RKE) System
Operation on page 2‑3. To open the liftgate, press the
touchpad under the liftgate handle.
The vehicle must be in P (Park)
to open the liftgate. To close the
liftgate, use the pull cup or pull
strap as an aid.
The liftgate will not open if the
battery is disconnected or has low
voltage. The liftgate will resume
operation when the battery is
reconnected and charged.
If the battery is properly connected
and has adequate voltage, and the
liftgate still will not function, the
vehicle should be taken to a dealer
for service.

Resetting the Power Foldaway
Mirrors
Reset the power foldaway mirrors if:
.The mirrors are accidentally
obstructed while folding.
.They are accidentally manually
folded/unfolded.
.The mirrors vibrate at normal
driving speeds.
Fold and unfold the mirrors one time
using the mirror controls to reset
them to their normal position.
A popping noise may be heard
during the resetting of the power
foldaway mirrors. This sound is
normal after a manual folding
operation.
Heated Mirrors
For vehicles with heated mirrors:
<(Rear Window Defogger):
Press to heat the mirrors.
See “Rear Window Defogger” under
Dual Automatic Climate Control
System on page 8‑4 for more
information.
Automatic Dimming
Mirror
If the vehicle has the automatic
dimming mirror, the driver outside
mirror automatically adjusts for the
glare of headlamps behind you.
This feature is controlled by the
on and off setting on the inside
rearview mirror. See Automatic
Dimming Rearview Mirror on
page 2‑19 for more information.
Park Tilt Mirrors
If the vehicle has the memory
package, the outside mirrors have
a park tilt feature. This feature tilts
the outside mirrors to a preselected
position when the vehicle is in
R (Reverse). This allows the driver
to view the curb for parallel parking.
The passenger and/or driver mirror
returns to its original position
when the vehicle is shifted out
of R (Reverse), or the ignition is
turned off or to OFF/LOCK.
This feature can be turned on or
off through the Driver Information
Center (DIC). See Vehicle
Personalization (With DIC Buttons)
on page 5‑47 for more information.

Rear Window
Wiper/Washer
The rear wiper and rear wash button
is located on the instrument panel
below the climate control system.
Z(Rear Wiper): Press to turn the
rear wiper on and off. The wiper
speed cannot be changed.
Y (Wash): Press to spray
washer fluid on the rear window.
The window wiper will also come
on. Release the button when
enough fluid has been sprayed
on the window. The rear wiper
will run a few more cycles after
it is released. If the rear wiper
function was already on, prior
to pressing the wash button,
it stays on until the wiper button
is pressed again.
The rear window washer uses the
same fluid that is in the windshield
washer reservoir. See Washer Fluid
on page 10‑23.
Compass
Your vehicle may have a compass
in the Driver Information Center
(DIC). See Driver Information
Center (DIC) (With DIC Buttons) on
page 5‑25 orDriver Information
Center (DIC) (Without DIC Buttons)
on page 5‑30 for more information
about the DIC.
Compass Zone
The zone is set to zone eight upon
leaving the factory. Your dealer
will set the correct zone for your
location.
Under certain circumstances,
such as during a long distance
cross-country trip or moving to
a new state or province, it will
be necessary to compensate for
compass variance by resetting the
zone through the DIC if the zone
is not set correctly. Compass variance is the difference
between the earth's magnetic north
and true geographic north. If the
compass is not set to the zone
where you live, the compass may
give false readings. The compass
must be set to the variance zone
in which the vehicle is traveling.
To adjust for compass variance, use
the following procedure:
Compass Variance (Zone)
Procedure
1. Do not set the compass zone
when the vehicle is moving.
Only set it when the vehicle
is in P (Park).
Press the vehicle information

Power Outlets
The vehicle has three 12‐volt outlets
that can be used to plug in electrical
equipment, such as a cell phone or
MP3 player.
The power outlets are located on
the instrument panel below the
climate controls, at the rear of the
center console, and in the rear
cargo area. Lift the cover to access
the outlet and replace when not
in use.
{WARNING
Power is always supplied to the
outlets. Do not leave electrical
equipment plugged in when the
vehicle is not in use because the
vehicle could catch fire and cause
injury or death. Notice:
Leaving electrical
equipment plugged in for an
extended period of time while
the vehicle is off will drain the
battery. Always unplug electrical
equipment when not in use and
do not plug in equipment that
exceeds the maximum 20 ampere
rating.
Certain accessory plugs may not
be compatible with the accessory
power outlet and could overload
vehicle and adapter fuses. If a
problem is experienced, see your
dealer.

Lighting 6-7
Delayed Exit Lighting
Delayed exit lighting illuminates the
interior for a period of time after the
key is removed from the ignition.
The ignition must be off for delayed
exit lighting to work. When the key
is removed, interior illumination
activates and remains on until
one of the following occurs:
.The ignition is in ON/RUN.
.The power door locks are
activated.
.An illumination period of
20 seconds has elapsed.
If during the illumination period
a door is opened, the timed
illumination period will be canceled
and the interior lamps will remain
on because a door is open.
Parade Dimming
This feature automatically prohibits
the dimming of the instrument
panel displays in daylight while
the headlamps are on so that the
displays are still able to be seen.
Battery Load
Management
The vehicle has Electric Power
Management (EPM) that estimates
the battery's temperature and state
of charge. It then adjusts the voltage
for best performance and extended
life of the battery.
When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), you may see the voltage move up or down. This is
normal. If there is a problem, an
alert will be displayed.
The battery can be discharged at
idle if the electrical loads are very
high. This is true for all vehicles.
This is because the generator
(alternator) may not be spinning
fast enough at idle to produce
all the power needed for very
high electrical loads.
A high electrical load occurs when
several of the following are on,
such as: headlamps, high beams,
fog lamps, rear window defogger,
climate control fan at high speed,
heated seats, engine cooling fans,
trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs.
