HEADLIGHT SWITCH
The headlight switch is located on the left side of the
instrument panel. This switch controls the operation of the
headlights, parking lights, automatic headlights (if
equipped), instrument panel light dimming, cargo light/
trailer spotter lights (if equipped), and fog lights (if
equipped).

Headlight Switch Headlight Switch (Vehicles Sold In Canada)

NOTE:
Vehicles sold in Canada are equipped with a headlight
switch with an AUTO and ON detent but without an OFF
detent. Headlights will be deactivated when the headlight
switch is placed in the parking lights position. However,
the Daytime Running Lights (DRLs) will be activated along
with the front and rear marker lights. The DRLs may be
deactivated when the parking brake is engaged.
To turn on the headlights, rotate the headlight switch
clockwise. When the headlight switch is on, the parking
lights, taillights, license plate light and instrument panel
lights are also turned on. To turn off the headlights, rotate
the headlight switch back to the O (off) position.
WARNING!
 Vehicle exhaust contains carbon monoxide, a
dangerous gas. Do not run your vehicle in the garage
while programming the transceiver. Exhaust gas can
cause serious injury or death.
 Your motorized door or gate will open and close while
you are programming the universal transceiver.
Do not program the transceiver if people, pets or
other objects are in the path of the door or gate. Only
use this transceiver with a garage door opener that
has a “stop and reverse” feature as required by
Federal safety standards. This includes most garage
door opener models manufactured after 1982.
Do not use a garage door opener without these
safety features.

NOTE:For vehicles sold in Canada, rotate the headlight switch
clockwise from the parking lights and instrument panel
lights position to the first detent to turn on headlights,
parking lights, and instrument panel lights. Rotate the
headlight switch to the second detent for the AUTO
position.
NOTE:
Your vehicle is equipped with plastic headlight and fog
light (if equipped) lenses that are lighter and less
susceptible to stone breakage than glass lights. Plastic
is not as scratch resistant as glass and therefore
different lens cleaning procedures must be followed.
 To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth.
To remove road dirt, wash with a mild soap solution
followed by rinsing.
MULTIFUNCTION LEVER
The multifunction lever is located on the left side of the
steering column.

Multifunction Lever

DAYTIME RUNNING LIGHTS (DRLS)
The Daytime Running Lights (DRLs) come on whenever the
engine is running, and the low beams are not on. The
lights will remain on until the ignition is placed in the OFF
or ACC position, or the parking brake is engaged.
NOTE:
For vehicles sold in Canada, the Daytime Running
Lights will automatically deactivate when the front fog
lights are turned on.
 If allowed by law in the country in which the vehicle was
purchased, the Daytime Running Lights can be turned
on and off using the Uconnect system
Úpage 191.
 On some vehicles, the Daytime Running Lights may
deactivate, or reduce intensity, on one side of the
vehicle (when a turn signal is activated on that side), or
on both sides of the vehicle (when the hazard warning
lights are activated).
HIGH/LOW BEAM SWITCH
Push the multifunction lever toward the instrument panel
to switch the headlights to high beams. Pulling the
multifunction lever back will turn the low beams on.
AUTOMATIC HIGH BEAM HEADLAMP
C
ONTROL — IF EQUIPPED
The Automatic High Beam Headlamp Control system
provides increased forward lighting at night by automating
high beam control through the use of a camera mounted
on the inside rearview mirror or a windshield mounted
camera. These cameras detect vehicle specific light and
automatically switch from high beams to low beams until
the approaching vehicle is out of view.
NOTE:
 The Automatic High Beam Headlamp Control can be
turned on or off by selecting “ON” under “Auto Dim
High Beams” within your Uconnect Settings
Úpage 191, as well as turning the headlight switch to
the AUTO position.
 Broken, muddy, or obstructed headlights and taillights
of vehicles in the field of view will cause headlights to
remain on longer (closer to the vehicle). Also, dirt, film,
and other obstructions on the windshield or camera
lens will cause the system to function improperly.
 If the windshield or Automatic High Beam Headlamp
Control mirror is replaced, the mirror must be re-aimed
to ensure proper performance. See a local authorized
dealer.
 To opt out of the Advanced Auto High Beam Sensitivity
Control (default) and enter Reduced High Beam Sensi -
tivity Control (not recommended), toggle the high beam
lever six full on/off cycles within 10 seconds of placing
the ignition in the ON position. The system will return to
the default setting upon placing the ignition in the OFF
position.
CAUTION!
Do not use abrasive cleaning components, solvents,
steel wool or other abrasive materials to clean the
lenses.

When the vehicle is turned off, be sure to unplug any
equipment as to not drain the battery of the vehicle. All
accessories connected to the outlet(s) should be removed
or turned off when the vehicle is not in use to protect the
battery against discharge.
POWER INVERTER — IF EQUIPPED
A 115 Volt (400 Watts maximum) inverter may be located
inside the center console towards the right hand side. This
inverter can power cellular phones, electronics and other
low power devices requiring power up to 400 Watts.
Certain video game consoles exceed this power limit, as
will most power tools.

Center Console Power Inverter Outlet

There is also a second 115 Volt (400 Watts maximum)
power inverter located on the rear of the center console.
This inverter can power cellular phones, electronics and
other low power devices requiring power up to 400 Watts. Certain video game consoles exceed this power limit, as
will most power tools.
All power inverters are designed with built-in overload
protection. If the power rating of 400 Watts is exceeded,
the power inverter shuts down. Once the electrical device
has been removed from the outlet the inverter should
reset.

Rear Center Console Power Inverter Outlet

NOTE:
400 Watts is the maximum for the inverter, not each
outlet. If three outlets are in use, 400 Watts is shared
amongst the devices plugged in.
If equipped with a front bench seat, there may be a
115 Volt (400 Watts maximum) inverter located to the
right of the center stack, just below the climate controls.
This inverter can power cellular phones, electronics and
other low power devices requiring power up to 400 Watts.
WARNING!
To avoid serious injury or death:
 Only devices designed for use in this type of outlet
should be inserted into any 12 Volt outlet.
 Do not touch with wet hands.
 Close the lid when not in use and while driving the
vehicle.
 If this outlet is mishandled, it may cause an electric
shock and failure.
CAUTION!
Many accessories that can be plugged in draw power
from the vehicle's battery, even when not in use
(i.e., cellular phones, etc.). Eventually, if plugged in
long enough, the vehicle's battery will discharge suffi -
ciently to degrade battery life and/or prevent the
engine from starting.
 Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.), will discharge the
battery even more quickly. Only use these intermit -
tently and with greater caution.
 After the use of high power draw accessories, or long
periods of the vehicle not being started (with acces -
sories still plugged in), the vehicle must be driven a
sufficient length of time to allow the generator to
recharge the vehicle's battery.
CAUTION!

NOTE:
The charging system is independent from load reduc -
tion. The charging system performs a diagnostic on the
charging system continuously.
 If the Battery Charge Warning Light is on it may indicate
a problem with the charging system
Úpage 108.
The electrical loads that may be switched off (if equipped),
and vehicle functions which can be affected by load
reduction:
 Heated Seats / Vented Seats / Heated Wheel
 Rear Defroster And Heated Mirrors
 HVAC System
 115 Volts AC Power Inverter System
 Audio and Telematics System
Loss of the battery charge may indicate one or more of the
following conditions:
 The charging system cannot deliver enough electrical
power to the vehicle system because the electrical
loads are larger than the capability of charging system.
The charging system is still functioning properly.
 Turning on all possible vehicle electrical loads
(e.g. HVAC to max settings, exterior and interior lights,
overloaded power outlets +12 Volts, 115 Volts AC, USB
ports) during certain driving conditions (city driving,
towing, frequent stopping). 
Installing options like additional lights, upfitter
electrical accessories, audio systems, alarms and
similar devices.
 Unusual driving cycles (short trips separated by long
parking periods).
 The vehicle was parked for an extended period of time
(weeks, months).
 The battery was recently replaced and was not charged
completely.
 The battery was discharged by an electrical load left on
when the vehicle was parked.
 The battery was used for an extended period with the
engine not running to supply radio, lights, chargers,
+12 Volt portable appliances like vacuum cleaners,
game consoles and similar devices.
What to do when an electrical load reduction action
message is present (“Battery Saver On” or “Battery Saver
Mode”)
During a trip:
 Reduce power to unnecessary loads if possible:
 Turn off redundant lights (interior or exterior).
 Check what may be plugged in to power outlets
+12 Volts, 115 Volts AC, USB ports.
 Check HVAC settings (blower, temperature).
 Check the audio settings (volume). After a trip:

Check if any aftermarket equipment was installed
(additional lights, upfitter electrical accessories, audio
systems, alarms) and review specifications if any
(load and Ignition Off Draw currents).
 Evaluate the latest driving cycles (distance, driving
time and parking time).
 The vehicle should have service performed if the
message is still present during consecutive trips and
the evaluation of the vehicle and driving pattern did not
help to identify the cause.

RED WARNING LIGHTS
Air Bag Warning Light
This warning light will illuminate to indicate a
fault with the air bag, and will turn on for four to
eight seconds as a bulb check when the
ignition is placed in the ON/RUN or ACC/ON/
RUN position. This light will illuminate with a single chime
when a fault with the air bag has been detected, it will stay
on until the fault is cleared. If the light is either not on
during startup, stays on, or turns on while driving, have the
system inspected at an authorized dealer as soon as
possible.
Brake Warning Light
This warning light monitors various brake
functions, including brake fluid level and
parking brake application. If the brake light
turns on it may indicate that the parking brake
is applied, that the brake fluid level is low, or that there is
a problem with the Anti-Lock Brake System reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition has
been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake,
and a brake pedal pulsation may be felt during each stop. The dual brake system provides a reserve braking capacity
in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp cornering
maneuvers, which change fluid level conditions. The
vehicle should have service performed, and the brake
fluid level checked.
If brake failure is indicated, immediate repair is necessary.
Vehicles equipped with the Anti-Lock Brake System (ABS)
are also equipped with Electronic Brake Force Distribution
(EBD). In the event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light. Immediate
repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for
approximately two seconds.
The light should then turn off unless the parking brake is
applied or a brake fault is detected. If the light does not
illuminate, have the light inspected by an authorized
dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN position.
NOTE:This light shows only that the parking brake is applied.
It does not show the degree of brake application.
Battery Charge Warning Light
This warning light will illuminate when the
battery is not charging properly. If it stays on
while the engine is running, there may be a
malfunction with the charging system. Contact
an authorized dealer as soon as possible.
This indicates a possible problem with the electrical
system or a related component.
Door Open Warning Light
This indicator will illuminate when a door is
ajar/open and not fully closed.
NOTE:If the vehicle is moving there will also be a single chime.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed. It
will take longer to stop the vehicle. You could have a
collision. Have the vehicle checked immediately.

Anti-Lock Brake System (ABS)
Warning Light
This warning light monitors the ABS. The light
will turn on when the ignition is placed in the
ON/RUN or ACC/ON/RUN position and may
stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, then
the Anti-Lock portion of the brake system is not
functioning and service is required as soon as possible.
However, the conventional brake system will continue to
operate normally, assuming the Brake Warning Light is not
also on.
If the ABS light does not turn on when the ignition is placed
in the ON/RUN or ACC/ON/RUN position, have the brake
system inspected by an authorized dealer.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illuminated
