Parade Dimming
This feature does not let the
instrument panel backlight dim
during daylight hours while the key
is in the ignition and the headlamps
are on. Parade dimming
automatically works with the light
sensor, located on top of the
dashboard. If it is dark enough
outside and the parking lamps are
on, the backlight on the instrument
panel can be adjusted by turning the
instrument panel brightness knob
clockwise or counterclockwise to
brighten or dim the lighting. See
Instrument Panel Illumination
Control on page 6‑7.
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 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.

Lighting 6-9
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 BATTERY
VOLTS LOW. If this message is
displayed, it is recommended that
the driver reduce the electrical loads
as much as possible. SeeDriver
Information Center (DIC) on
page 5‑27.Battery Power Protection
This feature helps to prevent battery
drain if accessory lamps are left on.
If accessory lamps such as the
vanity mirror, cargo, reading,
console, or glove box are left on,
they automatically time out after
about 20 minutes. To reset the
battery protection, all of the above
lamps must be turned off or the
ignition must be in the ACC/
ACCESSORY position.
Exterior Lighting Battery
Saver
The exterior lamps turn off about
10 minutes after the ignition is
turned to LOCK/OFF, if the parking
lamps or headlamps have been left
on. This protects against draining
the battery. The battery saver does
not work if the headlamps are
turned on after the ignition is turned
to LOCK/OFF.
To keep the lamps on for more than
10 minutes, turn the lamps back on
with the exterior lamp control.

9-10 Driving and Operating
Blizzard Conditions
Being stuck in snow can be a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use theRoadside
Service (U.S. and Canada) on
page 13‑7 orRoadside Service
(Mexico) on page 13‑9. To get help
and keep everyone in the
vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{WARNING
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO) which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
(Continued)
WARNING (Continued)
If the vehicle is stuck in the snow:
.Clear away snow from around
the base of your vehicle,
especially any that is blocking
the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about 5 cm
(2 in) on the side of the
vehicle that is away from the
wind to bring in fresh air.
.Fully open the air outlets on
or under the instrument
panel.
.Adjust the climate control
system to a setting that
circulates the air inside the
vehicle and set the fan speed
to the highest setting. See
“Climate Control Systems” in
the Index.
(Continued)
WARNING (Continued)
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑26.
Run the engine for short periods
only as needed to keep warm, but
be careful.
To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat this
until help arrives but only when you
feel really uncomfortable from the
cold. Moving about to keep warm
also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help
with the headlamps. Do this as little
as possible to save fuel.

9-50 Driving and Operating
When the System Does Not
Seem to Work Properly
The rear vision camera system
might not work properly or display a
clear image if the following occurs:
.It is dark.
.The sun or the beam of
headlamps is shining directly
into the camera lens.
.Ice, snow, mud, or anything else
builds up on the camera lens.
Clean the lens, rinse it with
water, and wipe it with a soft

.The back of the vehicle is in an
accident. The position and
mounting angle of the camera
can change or the camera can
be affected. Be sure to have
the camera and its position and
mounting angle checked at your
dealer.
.There are extreme temperature
changes.
Fuel
Use of the recommended fuel is
an important part of the proper
maintenance of this vehicle. To help
keep the engine clean and maintain
optimum vehicle performance, we
recommend the use of gasoline
advertised as TOP TIER Detergent
Gasoline.
Look for the TOP TIER label on the
fuel pump to ensure gasoline meets
enhanced detergency standards
developed by auto companies. A list
of marketers providing TOP TIER
Detergent Gasoline can be found at
www.toptiergas.com.
The eighth digit of the Vehicle
Identification Number (VIN) shows
the code letter or number that
identifies the vehicle's engine.
The VIN is at the top left of the
instrument panel. SeeVehicle
Identification Number (VIN) on
page 12‑1.

Headlamp Aiming
The vehicle has a visual optical
headlamp aiming system. The aim
has been preset at the factory and
should need no further adjustment.
However, if the vehicle is damaged
in a crash, the headlamp aim may
be affected and adjustment may be
necessary.
If oncoming vehicles flash their high
beams at you, this may also mean
the vertical aim needs to be
adjusted.
It is recommended that the vehicle
is taken to your dealer for service if
the headlamps need to be re-aimed.
It is possible, however, to re-aim the
headlamps as described.

Vehicle Care 10-35
The vehicle should:
.Be placed so the headlamps
are 7.6 m (25 ft) from a light
colored wall.
.Have all four tires on a level
surface which is level all the
way to the wall.
.Be placed so it is perpendicular
to the wall.
.Not have any snow, ice, or mud
on it.
.Be fully assembled and have all
other work stopped while
headlamp aiming is being
performed.
.Be loaded with a full tank of fuel
and one person or 75 kg
(160 lbs) sitting on the
driver seat.
.Have all tires properly inflated.
.Have the spare tire (if equipped)
in its original location in the
vehicle.Headlamp aiming is done with the
vehicle's low-beam headlamps. The
high-beam headlamps will be
correctly aimed if the low-beam
headlamps are aimed properly.
To adjust the vertical aim:
1. Open the hood. See
Hood on
page 10‑5 for more information.

4. At a wall, measure from theground upward (A) to the
recorded distance from
Step 3 and mark it.
5. Draw or tape a horizontal line (B) the width of the vehicle at the
wall where it was marked in
Step 4.
Notice: Do not cover a headlamp
to improve beam cut-off when
aiming. Covering a headlamp may
cause excessive heat build-up
which may cause damage to the
headlamp.
6. Turn on the low-beam
headlamps and place a piece of
cardboard or equivalent in front
of the headlamp not being aimed. This should allow only
the beam of light from the
headlamp being aimed to be
seen on the flat surface.

7. Locate the vertical headlamp aiming screws, which are under
the hood near each headlamp
assembly. They are covered by
rubber caps.
The adjustment screw can be
turned with a 6 mm hex driver.
8. Turn the vertical aiming screw until the headlamp beam is
aimed to the horizontal tape line. Turn it clockwise or
counterclockwise to raise or
lower the angle of the beam.
The top edge of the cut-off
should be positioned at the
bottom edge of the horizontal
tape line.9. Make sure that the light from the
headlamp is positioned at the
bottom edge of the horizontal
tape line. The lamp on the
left (A) shows the correct
headlamp aim. The lamp on the
right (B) shows the incorrect
headlamp aim.
