50GETTING TO KNOW YOUR VEHICLE
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 Once the turn signal is no
longer active, the DRL lamp will illuminate.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 Ucon -
nect 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.

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 the vehicle while
the steering wheel is being turned.
The adaptive lights are automatically activated
when the vehicle is traveling above approxi -
mately 5 mph (8 km/h).
This system can be turned on/off through the

STARTING AND OPERATING221
(Continued)
Starting Fluids
The engine is equipped with an automatic elec -
tric air preheating system. If the instructions in
this manual are followed, the engine should
start in all conditions.
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!
Starting fluids or flammable liquids must
never be used in the Cummins diesel engine
(see Warning label). Never pour diesel fuel,
flammable liquid, starting fluids (ether) into
the air cleaner canister, air intake piping, or
turbocharger inlet in an attempt to start the
vehicle. This could result in a flash fire and
explosion causing serious personal injury and
engine damage.
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 make
sure the keyless ignition node is in the
“OFF” mode, remove the key fob from the
vehicle and lock the 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 chil -
dren, 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.

(Continued)
ENGINE RUNAWAY — DIESEL ENGINE
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.
REFUELING THE VEHICLE — GAS ENGINE
The fuel filler cap (gas cap) is located behind the
fuel filler door, on the left side of the vehicle.
Open the fuel door and remove the fuel filler cap
by turning it counter-clockwise.
Fuel Filler Cap

NOTE:
When removing the fuel filler cap, lay the cap
tether in the hook, located on the fuel filler door.
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:
1. Turn the ignition switch to the OFF position.
2. Using a CO2 or dry chemical type fire
extinguisher, direct the spray from the fire
extinguisher into the grille on the driver side
so that the spray enters the engine air intake.
The inlet for the engine air intake is located
behind the drivers side headlamp and
receives air through the grille.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the gas cap is
removed or the tank is being filled.
Never add fuel to the vehicle when the
engine is running.
A fire may result if gasoline is pumped into
a portable container that is inside of a
vehicle. You could be burned. Always place
gas containers on the ground while filling.
CAUTION!
Damage to the fuel system or emissions
control system could result from using an
improper fuel tank filler tube cap.
A poorly fitting fuel filler cap could let impu -
rities into the fuel system.
A poorly fitting fuel filler cap may cause the
“Malfunction Indicator Light (MIL)” to turn
on.
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling. When the
fuel nozzle “clicks” or shuts off, the fuel
tank is full.
