4. Snap the transmitter back together.
Remote Vehicle Start
This vehicle may have a remote start
feature. This feature allows you to start the
engine from outside the vehicle. It may also
start the vehicle's heating or air conditioning
systems. See Climate Control Systems 0119.
Laws in some local communities may restrict
the use of remote starters. For example,
some laws may require a person using
remote start to have the vehicle in view
when doing so. Check local regulations for
any requirements on remote starting of
vehicles.
Do not use the remote start feature if the
vehicle is low on fuel. The vehicle may run
out of fuel.
The RKE transmitter range may be less while
the vehicle is running.
Other conditions can affect the performance
of the transmitter. See Remote Keyless Entry
(RKE) System 08.
/:This button will be on the RKE
transmitter if the vehicle has remote start.
To start the engine using the remote start
feature:
1. Press and release
Qon the transmitter.
2. Immediately press and hold
/until the
turn signal lamps flash. If you cannot see
the lamps, press and hold
/for at least
four seconds.
When the engine starts, the parking
lamps will turn on and remain on while
the engine is running. The doors will be
locked.
The engine will continue to run for
10 minutes. After 30 seconds, repeat the
steps if a 10-minute extension is desired.
Remote start can be extended only once.
After entering the vehicle during a remote
start, turn the ignition on to drive the
vehicle.
A maximum of two remote starts or a start
with an extension are allowed between
ignition cycles. If the remote start procedure is used again
before the first 10-minute time frame has
ended, the first 10 minutes will immediately
expire and the second 10-minute time frame
will start.
After the engine has been remote started
two times or a start with an extension, the
ignition must be turned on and then off
before the remote start procedure can be
used again.
To cancel a remote start do any of the
following:
.Press and hold/until the parking lamps
turn off.
.Turn on the hazard warning flashers.
.Turn the ignition on and then off.
The remote vehicle start feature will not
operate if:
.The key is in the ignition.
.The hood is open.
.The hazard warning flashers are on.
.There is an emission control system
malfunction. See Malfunction Indicator
Lamp (Check Engine Light) 076.
.The engine coolant temperature is
too high.
.The oil pressure is low.

Interior Rearview Mirrors
Adjust the rearview mirror for a clear view
of the area behind the vehicle. Do not spray glass cleaner directly on the
mirror. Use a soft towel dampened with
water.
Manual Rearview Mirror
Push the tab forward for daytime use and
pull it rearward for nighttime use to avoid
glare of the headlamps from behind.
Backup Video Manual Mirror
If equipped, this manual dimming mirror
provides a camera view of the area behind
the vehicle. The video display feature comes
on when the vehicle is shifted in R (Reverse),
and turns off when the vehicle is shifted out
of R (Reverse).
Troubleshooting
If the vehicle is in R (Reverse) and a blue
screen is displayed in the mirror and then
the display shuts off, see your dealer for
service.

Warning
Never leave a child, a helpless adult, or a
pet alone in a vehicle, especially with the
windows closed in warm or hot weather.
They can be overcome by the extreme
heat and suffer permanent injuries or
even death from heat stroke.
Manual Windows
Operate the manual windows by turning the
hand crank on each door to raise or lower
the side door windows.

68 Instruments and Controls
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) Procedure1. Do not set the compass zone when the vehicle is moving. Only set it when the
vehicle is in P (Park).
Press
Tuntil PRESSVTO CHANGE
COMPASS ZONE displays.
2. Find the vehicle's current location and variance zone number on the map.
Zones 1 through 15 are available. 3. Press
Vto scroll through and select the
appropriate variance zone.
4. Press
3until the vehicle heading, for
example, N for North, is displayed in
the DIC.
5. If calibration is necessary, calibrate the compass. See “Compass Calibration
Procedure” following.
Compass Calibration
The compass can be manually calibrated.
Only calibrate the compass in a magnetically
clean and safe location, such as an open
parking lot, where driving the vehicle in
circles is not a danger. It is suggested to
calibrate away from tall buildings, utility
wires, manhole covers, or other industrial
structures, if possible.
If CAL should ever appear in the DIC display,
the compass should be calibrated.
If the DIC display does not show a heading,
for example, N for North, or the heading
does not change after making turns, there
may be a strong magnetic field interfering
with the compass. Such interference may be
caused by a magnetic CB or cell phone
antenna mount, a magnetic emergency
light, magnetic note pad holder, or any other magnetic item. Turn off the vehicle,
move the magnetic item, then turn on the
vehicle and calibrate the compass.
To calibrate the compass, use the following
procedure:
Compass Calibration Procedure
1. Before calibrating the compass, make sure the compass zone is set to the
variance zone in which the vehicle is
located. See “Compass Variance (Zone)
Procedure” earlier in this section.
Do not operate any switches such as
window, climate controls, seats, etc.
during the calibration procedure.
2. Press
Tuntil PRESSVTO CALIBRATE
COMPASS displays.
3. Press
Vto start the compass calibration.
4. The DIC will display CALIBRATING: DRIVE IN CIRCLES. Drive the vehicle in tight
circles at less than 8 km/h (5 mph) to
complete the calibration. The DIC will
display CALIBRATION COMPLETE for a few
seconds when the calibration is
complete. The DIC display will then
return to PRESS
VTO CALIBRATE
COMPASS.

Lighting 95
The exterior lamps and dome lamp remain
on after the door is closed for a set amount
of time, then automatically turn off.
The exterior lamps turn off immediately by
turning the exterior lamp control off. The
exit lighting for exterior lights can be
changed. SeeVehicle Personalization 086.
Battery Load Management
The vehicle may have 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 that
is 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. 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
SERVICE BATTERY CHARGING SYSTEM. If this
messages displays, it is recommended that
the driver reduce the electrical loads as
much as possible.
Battery Power Protection
This feature shuts off the interior lamps if
they are left on for more than 10 minutes
when the ignition is off. This helps to
prevent the battery from running down.
Exterior Lighting Battery Saver
The exterior lamps turn off about 10 minutes
after the ignition is turned off, if the parking
lamps or headlamps have been manually
left on. This protects against draining the
battery. To restart the 10-minute timer, turn
the exterior lamp control to the
Oposition
and then back to the
;or2position.
To keep the lamps on for more than
10 minutes, the ignition must be on or in
ACC/ACCESSORY.
