GETTING TO KNOW YOUR VEHICLE45
Daytime Running Lights (DRLs)
The headlights on your vehicle will illuminate
when the engine is started and the transmis -
sion is in any gear except PARK. This provides a
constant "lights on" condition until the ignition is
placed in the OFF position. The lights illuminate
at less than half of normal intensity. If the
parking brake is applied, the Daytime Running
Lights (DRLs) will turn off. Also, if a turn signal is
activated, the DRL lamp on the same side of the
vehicle may turn off for the duration of the turn
signal activation. Once the turn signal is no
longer active, the DRL lamp will illuminate.
NOTE:
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, refer to “Uconnect Settings”
in “Multimedia” for further information.
High/Low Beam Switch
Push the multifunction lever toward the instru-
ment panel to switch the headlights to high
beam. Pulling the multifunction lever back
toward the steering wheel will turn the low
beams back on, or shut the high beams off.
Automatic High Beam Headlamp Control —
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 digital camera mounted on the
inside rearview mirror or forward facing camera.
This camera detects vehicle specific light and
automatically switches 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, as well as turning the
headlight switch to the AUTO position. Refer
to “Uconnect Settings” in “Multimedia” for
further information.
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 improp -
erly.
To opt out of the Advanced Auto High Beam
Sensitivity Control (default) and enter
Reduced High Beam Sensitivity Control (not
recommended), on vehicles equipped with
mirror controlled automatic high beams and
without the forward facing camera, 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 when the ignition is OFF.
If the windshield or Automatic High Beam Head -
lamp Control mirror is replaced, the mirror must
be re-aimed to ensure proper performance. See
a local authorized dealer.
To Activate

1. The Automatic High Beams are enabled through the Uconnect system. Refer to
“Uconnect Settings” in “Multimedia” for
further information.

2. Turn the headlight switch to the AUTO head -
light position.
3. Push the multifunction lever away from you (toward front of vehicle) to engage the high
beam mode.

46GETTING TO KNOW YOUR VEHICLE
NOTE:
The Automatic High Beams will not activate until
the vehicle is at or above 12 mph (20 km/h).
To Deactivate

1. Pull the multifunction lever toward you (or
rearward in vehicle) to manually deactivate
the system (normal operation of low
beams).

2. Push back on the multifunction lever to reactivate the system.
The Automatic High Beams can also be deacti -
vated through the Uconnect system. Refer to
“Uconnect Settings” in “Multimedia” for further
information.
Flash-To-Pass
You can signal another vehicle with your head -
lights by lightly pulling the multifunction lever
toward you. This will cause the high beam head -
lights to turn on, and remain on, until the lever
is released.
Automatic Headlights — If Equipped
This system automatically turns your headlights
on or off based on ambient light levels. To turn
the system on, turn the headlight switch clock-
wise, aligning the indicator with the AUTO on the
headlight switch. When the system is on, the
Headlight Time Delay feature is also on. This
means your headlights will stay on for up to 90
seconds after you place the ignition switch in
the OFF position. To turn the Automatic System
off, turn the headlight switch counterclockwise
to the O (off) position.
NOTE:
The engine must be running before the head -
lights will come on in the Automatic mode.
Parking Lights And Panel Lights
To turn on the parking lights and instrument
panel lights, from the O (off) position, rotate the
headlight switch clockwise to the first detent. To
turn off the parking lights, rotate the headlight
switch back to the O (off) position.
Directional LED Headlamp System — If
Equipped
This is a system consisting of LED (low/high
beam) headlights that incorporate dynamic
cornering with 5-degree inboard/15-degree
outboard swivel. The headlights continuously
and automatically adapt to the driving condi -
tions around bends or when cornering based on
steering wheel angle.
The system directs the headlights to light up the
road in the best way, taking into account the
speed of the vehicle and the bend or corner
angle, as well as the speed of steering.
The adaptive lights are automatically activated
when the vehicle is traveling above approxi -
mately 5 mph (8 km/h).
Headlights On With Wipers (Available With
Automatic Headlights Only)
When this feature is active, the headlights will
turn on approximately 10 seconds after the
wipers are turned on if the headlight switch is
placed in the AUTO position. In addition, the
headlights will turn off when the wipers are
turned off, if they were turned on by this feature.

194STARTING AND OPERATING
NORMAL OPERATION — DIESEL ENGINE
Observe the following when the engine is oper -
ating.
All message center lights are off.
Malfunction Indicator Light (MIL) is off.
Engine oil pressure is above 10 psi (69 kPa)
at idle.
Voltmeter operation:
The voltmeter may show a gauge fluctuation at
various engine temperatures. This cycling oper -
ation is caused by the post-heat cycle of the
intake manifold heater system. The number of
cycles and the length of the cycling operation is
controlled by the engine control module.
Post-heat operation can run for several
minutes, and then the electrical system and
voltmeter needle will stabilize. The cycling action will cause temporary
dimming of the headlamps, interior lamps, and
also a noticeable reduction in blower motor
speed.
Cold Weather Precautions
Operation in ambient temperature below 32°F
(0°C) may require special considerations. The
following charts suggest these options:
WARNING!
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build up may cause serious injury or
death.
When leaving the vehicle, always remove
the key fob and lock your vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat
-
tended is dangerous for a number of
reasons. A child or others could be seriously
or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the gear selector. Do not
leave the key fob in or near the vehicle (or
in a location accessible to children), and do
not leave the ignition of a vehicle equipped
with Keyless Enter-N-Go in the ACC or ON/
RUN mode. A child could operate power
windows, other controls, or move the
vehicle.

ENGINE RUNAWAY
Diesel engine runaway is a rare condition
affecting diesel engines, where the engine
consumes its own lubrication oil and runs at
higher and higher RPM until it overspeeds to a
point where it destroys itself due to either
mechanical failure or engine seizure through
lack of lubrication.
WARNING!
In case of engine runaway due to flammable
fumes from fuel spills or turbocharger oil
leaks being sucked into the engine, do the
following to help avoid personal injury and/or
vehicle damage:
Turn the ignition switch to the OFF position.
Using a CO2 or dry chemical type fire extin -
guisher, direct the spray from the fire extin -
guisher into the grille on the passenger side
