a:Slow wipes.
9:Use to turn the wipers off.
When driving during the day and the
wipers are activated, the headlamps
automatically turn on after
completing eight wipe cycles.
{Warning
In freezing weather, do not use
the washer until the windshield is
warmed. Otherwise the washer
fluid can form ice on the
windshield, blocking your vision.
{Warning
Before driving the vehicle, always
clear snow and ice from the hood,
windshield, roof, and rear of the
vehicle, including all lamps and
windows. Reduced visibility from
snow and ice buildup could lead
to a crash. Clear ice and snow from the wiper
blades before using them. If frozen
to the windshield, carefully loosen or
thaw them. Damaged blades should
be replaced.
Windshield Washer
The windshield wiper paddle is on
top of the turn signal lever.
L:
Push the paddle to spray
washer fluid on the windshield. The
wipers will clear the window and
then either stop or return to the
preset speed.
Compass
This vehicle may have a compass in
the Driver Information Center (DIC).
Compass Zone
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:

Procedure
1. Do not set the compass zone when the vehicle is moving.
Only set it when the vehicle is
in P (Park).

112 Lighting
The headlamps will also stay on
after exiting the vehicle. This feature
may be programmable. SeeVehicle
Personalization 0104.
If the feature is not programmable,
exit lighting is automatic. When it is
dark enough outside, the exterior
lamps remain on for 30 seconds
after the ignition is turned off.
Lights On with Wipers
If the windshield wipers are
activated in daylight with the engine
on, and the exterior lamp control is
in AUTO, the headlamps, parking
lamps, and other exterior lamps
come on. The transition time for the
lamps coming on varies based on
wiper speed. When the wipers are
not operating, these lamps turn off.
Move the exterior lamp control to
P
or;to disable this feature.
Hazard Warning Flashers
|: Press this button to make the
front and rear turn signal lamps
flash on and off. This warns others
that you are having trouble. Press
again to turn the flashers off.
When the hazard warning flashers
are on, the vehicle's turn signals will
not work.
Turn and Lane-Change
Signals
G: An arrow on the instrument
cluster flashes in the direction of the
turn or lane change.
To signal a turn, move the lever all
the way up or down.
To signal a lane change, raise or
lower the lever until the arrow starts
to flash. The turn signal
automatically flashes three times
and if the Tow/Haul Mode is active it
flashes six times. Holding the turn
signal lever for more than
one second causes the turn signals
to flash continually until the lever is
released.
The lever returns to its starting
position when released.

248 Vehicle Care
Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have the
headlamp wiring checked right away
if the lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.
Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using the
windshield wipers.
If the overload is caused by an
electrical problem and not snow or
ice, be sure to get it fixed.
Fuses and Circuit
Breakers
The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses and circuit
breakers. This greatly reduces the
chance of fires caused by electrical
problems.
Look at the silver-colored band
inside the fuse. If the band is broken
or melted, replace the fuse. Be sure
you replace a bad fuse with a new
one of the identical size and rating.
Engine Compartment
Fuse Block
The fuse block is in the engine
compartment on the driver side of
the vehicle.Vehicles with Upfitter Content

provisions and best practices.
Caution
Spilling liquid on any electrical
component on the vehicle may
damage it. Always keep the
covers on any electrical
component.
