or the door is not unlocked by pressingK
on the RKE transmitter during the 10-second
pre-alarm, the alarm will be activated.
If a door or the hood is opened without first
disarming the system, the turn signals will
flash and the horn will sound for about
30 seconds. The alarm system will then
re-arm to monitor for the next unauthorized
event.
Disarming the Alarm System
To disarm the alarm system or turn off the
alarm if it has been activated:
.PressKon the RKE transmitter.
.Start the vehicle.
To avoid setting off the alarm by accident:
.Lock the vehicle after all occupants have
left the vehicle and all doors are closed.
.Always unlock a door with the RKE
transmitter.
Unlocking the driver door with the key will
not disarm the system or turn off the alarm.
Detecting a Tamper Condition
IfKis pressed on the RKE transmitter and
the horn chirps three times, an alarm
occurred previously while the alarm system
was armed.
Immobilizer
See Radio Frequency Statement 0336.
Immobilizer Operation
This vehicle has a passive theft-deterrent
system.
The system does not have to be manually
armed or disarmed.
The vehicle is automatically immobilized
when the vehicle is turned off.
The system is automatically disarmed when
the ignition is turned from off to on.
The security light, in the instrument cluster,
comes on if there is a problem with arming
or disarming the theft-deterrent system. When trying to start the vehicle, the
security light comes on briefly when the
ignition is turned on.
If the engine does not start and the security
light stays on, there is a problem with the
system. Turn the ignition off and try again.
If the engine still does not start, and the
key appears to be undamaged, try another
ignition key. It may be necessary to check
the fuse. See
Fuses and Circuit Breakers
0 261. If the engine still does not start with
the other key, the vehicle needs service.
If the vehicle does start, the first key may
be faulty. See your dealer.
It is possible for the immobilizer system to
learn new or replacement keys. Up to eight
keys can be programmed for the vehicle. To
program additional transmitters, see Remote
Keyless Entry (RKE) System Operation 09.
Do not leave the transmitter or device that
disarms or deactivates the vehicle
theft-deterent system in the vehicle.
See your dealer to get a new key blank cut
exactly as the ignition key that operates the
system.

Instruments and Controls 77
Compass
The vehicle may have a compass display on
the Driver Information Center (DIC). The
compass receives its heading and other
information from the Global Positioning
System (GPS) antenna, StabiliTrak/Electronic
Stability Control (ESC), and vehicle speed
information.
The compass system is designed to operate
for a certain number of miles or degrees of
turn before needing a signal from the GPS
satellites. When the compass display shows
CAL, drive the vehicle for a short distance in
an open area where it can receive a GPS
signal. The compass system will
automatically determine when a GPS signal
is restored and provide a heading again.
Clock
Set the time and date using the
infotainment system. See "Time / Date"
underSettings 0146.
Power Outlets
For USB charging port locations, see the
infotainment manual. Accessory power outlets can be used to plug
in electrical equipment, such as a cell phone,
MP3 player, etc.
The vehicle may have accessory power
outlets:
.On the center stack below the climate
control system, if equipped.
.On the center floor console, if equipped.
.On the rear of the center storage console.
Lift the cover to access and replace when
not in use.
{Warning
Power is supplied to the outlets when the
ignition is on. When not in use, do not
leave electrical equipment plugged in. The
vehicle could catch fire and cause injury
or death.
Caution
Leaving electrical equipment plugged in
for an extended period of time while the
vehicle is off will drain the battery.
Always unplug electrical equipment when
(Continued)
Caution (Continued)
not in use and do not plug in equipment
that exceeds the maximum 15 amp
rating.
Certain power accessory plugs may not be
compatible with the accessory power outlet
and could overload vehicle or adapter fuses.
If a problem is experienced, see your dealer.
When adding electrical equipment, be sure
to follow the proper installation instructions
included with the equipment. See Add-On
Electrical Equipment 0234.
Caution
Hanging heavy equipment from the
power outlet can cause damage not
covered by the vehicle warranty. The
power outlets are designed for accessory
power plugs only, such as cell phone
charge cords.
Wireless Charging
If equipped, the vehicle has wireless
charging in front of the center floor console.
The system operates at 145 kHz and
wirelessly charges one Qi compatible
smartphone. The power output of the

104 Lighting
An arrow on the instrument cluster flashes
in the direction of the turn or lane change.
Move the turn signal lever all the way up or
down to signal a turn.
Raise or lower the lever for less than
one second until the arrow starts to flash to
signal a lane change. This causes the turn
signals to automatically flash three times.
Holding the turn signal lever for more than
one second will cause the turn signals to
flash until the lever is released.
The lever returns to its starting position
whenever it is released.
If after signaling a turn or a lane change the
arrows flash rapidly or do not come on, a
signal bulb could be burned out.
Replace any burned out bulbs. If a bulb is
not burned out, check the fuse. SeeFuses
and Circuit Breakers 0261.
Turn Signal On Chime
If the turn signal is left on for more than
1.2 km (0.75 mi), a chime sounds at each
flash of the turn signal. The message TURN
SIGNAL ON will also appear in the Driver
Information Center (DIC). To turn the chime
and message off, move the turn signal lever
to the off position.Fog Lamps
If equipped, the control is on the center of
the exterior lamp control, to the left of the
steering column.
The ignition must be on for the fog lamps
to come on.
#: Press to turn the fog lamps on or off.
A light will come on in the instrument
cluster.
When the fog lamps are turned on, the
parking lamps automatically turn on.
When the headlamps are changed to high
beam, the fog lamps go off. When the
high-beam headlamps are turned off, the fog
lamps will come on again.
Some localities have laws that require the
headlamps to be on with the fog lamps.
Exterior Cargo Lamps
The cargo lamp provides more light in the
cargo area of the vehicle, if needed. The
lamps inside the pickup box also turn on,
if equipped.
Press the switch down to turn the cargo
lamp on or off. The shift lever must be in
P (Park), R (Reverse), or N (Neutral) to
operate the cargo lamp.
Become familiar with and follow all state
and local laws that apply to cargo lamp
operation.

Electrical System
Electrical System Overload
The vehicle has fuses to protect against an
electrical system overload. Fuses also protect
power devices in the vehicle.
Replace a bad fuse with a new one of the
identical size and rating.
If there is a problem on the road and a fuse
needs to be replaced, there is a fuse puller
in the Engine Compartment Fuse Block.
Replace the fuse as soon as possible with
one of the same amperage rating.
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 damage
caused by electrical problems.
{Danger
Fuses and circuit breakers are marked
with their ampere rating. Do not exceed
the specified amperage rating when
replacing fuses and circuit breakers. Use
of an oversized fuse or circuit breaker can
result in a vehicle fire. You and others
could be seriously injured or killed.
To check a fuse, look at the silver-colored
band inside the fuse. If the band is broken
or melted, replace the fuse. Be sure to
replace a bad fuse with a new one of the
identical size and rating.
Fuses of the same amperage can be
temporarily borrowed from another fuse
location, if a fuse goes out. Replace the fuse
as soon as possible.
