3. Insert the new battery, positiveside facing down. Replace with
a CR2032 or equivalent
battery.
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 0143.
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
09.
/:This button will be on the RKE
transmitter if the vehicle has remote
start.
To start the engine using the remote
start feature:
1. Aim the RKE transmitter at the vehicle.
2. Press and release
Qon the
transmitter.
3. 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 remote 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:
. Aim the RKE transmitter at the
vehicle and press

On the lower portion of each mirror
there is an auxiliary convex mirror
that can be adjusted manually to
provide an extended field of view.
The mirrors can be manually folded
in or out.
Power Mirrors
If equipped with power mirrors,
select each mirror by turning the
knob clockwise for the passenger
side mirror or counterclockwise for
the driver side mirror. The center
position is neutral.Adjust the mirror angle by moving
the knob in the desired direction.
The auxiliary convex mirrors can
only be adjusted manually.
Folding Mirrors
Manual Folding Mirrors
The mirrors can be folded inward
toward the vehicle to prevent
damage when going through an
automatic car wash. Push the mirror
outward to return it to the original
position.
Side Blind Zone Alert
The vehicle may have Side Blind
Zone Alert. See
Side Blind Zone
Alert (SBZA) 0187.
Heated Mirrors
For vehicles with heated mirrors:
1:Press to heat the mirrors.
An indicator light in the button lights
when the outside heated mirrors are
activated.
See “Rear Window Defogger” under
Climate Control Systems 0143.
Interior Mirrors
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

2. Find the vehicle's currentlocation 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.

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

Lighting 115
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 isrecommended that the driver reduce
the electrical loads as much as
possible.
Battery Power Protection
This feature shuts off the dome
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.
