Compass Variance
Compass variance is the difference between earth’s
magnetic north and true geographic north. If the
mirror is not adjusted for compass variance, the
compass could give false readings.
The mirror is set in zone eight upon leaving the
factory. It will be necessary to adjust the compass
to compensate for compass variance if the
vehicle is driven outside zone eight. Under
certain circumstances, such as a long distance,
cross-country trip, it will be necessary to adjust the
compass variance.
To adjust for compass variance, do the following:
1. Find your current location and variance
zone number on the zone map. SeeAutomatic
Dimming Rearview Mirror with OnStar
®and
Compass on page 130for map information.
2. Press and hold the on/off button until a zone
number appears on the display.
3. Once the zone number appears on the display,
press the on/off button quickly until you reach
the correct zone number. If C or CAL appears
in the compass window, the compass may
need calibration. See “Compass Calibration”
listed previously.
Outside Power Mirrors
The controls for the
outside power mirrors
are located on the
driver’s door armrest.
Press the left or right side of the selector switch
located beneath the control pad to choose the left
or right mirror.
To adjust the mirror, press one of the four arrows
located on the control pad to move the mirror
in the direction you want it to go. Adjust each
outside mirror so that you can see a little of your
vehicle, and the area behind your vehicle.
The mirrors may also have an arrow that ashes
when the turn signal is used. SeeTurn and
Lane-Change Signals on page 162.

Tilt Wheel
A tilt wheel allows you to adjust the steering wheel
before you drive. You can also raise it to the
highest level to give your legs more room when
you exit and enter the vehicle.
The lever that allows you to tilt the steering wheel
is located on the left side of the steering column.
To tilt the wheel, hold
the wheel and pull the
lever toward you. Then
move the wheel to a
comfortable position and
release the lever to lock
the wheel in place.
Heated Steering Wheel
Your vehicle may have a heated steering wheel.
The button for this
feature is located on
the left side of the
steering wheel.
Press the button to turn the heated steering wheel
on or off. A light on the button will display when
the feature is turned on.
The steering wheel will take about three minutes
to start heating.

Windshield Washer
{CAUTION:
In freezing weather, do not use your
washer until the windshield is warmed.
Otherwise the washer uid can form ice
on the windshield, blocking your vision.
J(Washer Fluid):Press and release this
paddle, located at the top of the turn signal/
multifunction lever, to spray washer uid on the
windshield. The wipers will clear the windshield
and either stop or return to your preset speed. For
more washer cycles, press and hold the paddle.
_(Heated Washer Fluid):The heated
windshield washer uid system, if your vehicle has
this feature, may be used to help clear ice, snow,
tree sap, or bugs from your windshield. Sliding the
switch on the turn signal/multifunction lever to
this position and then releasing it will activate the
heated windshield washer uid system. This
activation will initiate four heated wash/wipe cycles.
The rst heated wash/wipe cycle may take up to
40 seconds to occur, depending on outside
temperature. After the rst wash/wipe cycle, it may
take up to 20 seconds for each of the remaining
cycles. The heated windshield washer uid system
may be turned off at any time by sliding the switch
on the turn signal/multifunction lever to this
position again.
When the heated windshield washer uid system
is activated under certain outside temperature
conditions, steam may ow out of the washer
nozzles for a short period of time before washer
uid is sprayed. This is a normal condition.
Washer Fluid Low Add Fluid will be displayed on
the Driver Information Center (DIC) when the
washer uid is low. SeeDIC Warnings and
Messages on page 221.

Electric Power 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 put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or 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 that is needed for very high electrical
loads.A high electrical load occurs when several of the
following loads are on: 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. It can
increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action
may be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Service
Battery Charging System. If this message is
displayed, it is recommended that the driver
reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 221.

The display is located
near the rear window
and can be seen
by looking over your
right shoulder.
The display has three color-coded lights. The
URPA lights are used to provide distance and
system information, along with beeps played out
the speakers.
How the System Works
When the shift lever is moved into REVERSE (R),
the rear display will briey illuminate to let you know
the display is operating correctly. URPA comes on
automatically when the shift lever is moved into
REVERSE (R). The system also does not work at a
reverse speed greater than 5 mph (8 km/h). To
remind you of this, the red light on the rear display
will ash.The system can be disabled using the Driver
Information Center (DIC). SeeDIC Controls and
Displays on page 212.
How the System Works when Backing
If the shift lever is in REVERSE (R), URPA detects
objects close to the rear bumper. The rst time an
object is detected a single beep will sound. If an
object is detected at a REVERSE (R) speed
between 0 mph (0km/h) and 5 mph (8 km/h), the
following describes what will occur based on your
distance to a detected object located behind the
vehicle:
At distances between 40 inches (1 m) and
8 ft (2.5 m), a single amber light will be lit.
At distances between 23 inches (0.6 m) and
40 inches (1 m), both amber lights will be lit.
At distances between 12 inches (0.3 m)
and 23 inches (0.6 m), all three lights
(amber/amber/red) will be lit.
At distances less than 12 inches (0.3 m), a
beeping sound will repeat for a short time and
all three lights (amber/amber/red) will be lit and
ashing.

When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a
temporary condition, the message PARK ASSIST
OFF will be displayed on the DIC and a red light will
be shown on the rear URPA display when the shift
lever is moved into REVERSE (R). This occurs
under the following conditions:
The driver disables the system. SeeDIC
Controls and Displays on page 212.
The parking brake pedal is pressed.
A trailer was attached to your vehicle, or a
bicycle or an object was hanging out of your
trunk during your last drive when you turned off
the vehicle. If the attached objects are removed
from your vehicle before the start of your next
drive, the system will return to normal operation
unless an object is detected when the vehicle is
shifted into REVERSE (R). If this occurs, URPA
assumes the object is still attached, so you will
have to wait until the vehicle is driven forward
above 15 mph (25 km/h) before URPA will
return to normal operation.
The ultrasonic sensors are not kept clean. So,
be sure to keep your vehicle’s rear bumper free
of mud, dirt, snow, ice, and slush. For cleaning
instructions, seeWashing Your Vehicle on
page 422. If the DIC still displays the PARK
ASSIST OFF message after cleaning the
bumper and driving forward at a speed of at
least 15 mph (25 km/h), see your dealer.
Other conditions that may affect system
performance include vibrations from a
jackhammer or the compression of air brakes
on a very large truck or other mechanical
devices that interfere with URPA performance.
When URPA is disabled without driver action
and the driver attempts to turn URPA back on
using the Driver Information Center (DIC), the
PARK ASSIST ON option will not be selectable
if the necessary conditions stated above for
normal system operation are not met.
As always, drivers should use care when backing
up a vehicle. Always look behind you, being sure to
check for other vehicles, obstructions and blind
spots.
