GETTING TO KNOW YOUR VEHICLE53
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.
NOTE:
Your vehicle is equipped with plastic head -
light 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 a turn signal is activated, the DRL lamp on
the same side of the vehicle will turn off for
the duration of the turn signal activation.
Once the turn signal is no longer active, the
DRL lamp will illuminate.
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 Ú page 237.
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.
CAUTION!
Do not use abrasive cleaning components,
solvents, steel wool or other abrasive
materials to clean the lenses.

21_DT_OM_EN_USC_t.book Page 53

54GETTING TO KNOW YOUR VEHICLE
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 237, as well as
turning the headlight switch to the AUTO posi -
tion.
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.
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 Sensitivity Control (not
recommended), toggle the high beam lever
6 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.
FLASH-TO-PASS
You can signal another vehicle with your
headlights by lightly pulling the multifunction
lever toward you. This will cause the high beam
headlights to turn on, and remain on, until the
lever is released.
AUTOMATIC HEADLIGHTS — IF EQUIPPED
This system automatically turns the headlights
on or off according to ambient light levels. To
turn the system on, rotate the headlight switch
to the AUTO position.
When the system is on, the Headlight Delay
feature is also on. This means the headlights
will stay on for up to 90 seconds after you place
the ignition into the OFF position. To turn the
automatic headlights off, turn the headlight
switch out of the AUTO position.
NOTE:
The engine must be running before the head -
lights will turn on in the Automatic Mode.
PARKING LIGHTS AND PANEL LIGHTS
To turn on the parking lights and instrument
panel lights, rotate the headlight switch
clockwise. To turn off the parking lights, rotate
the headlight switch back to the O (off) position.
AUTOMATIC HEADLIGHTS WITH WIPERS
If your vehicle is equipped with Automatic
Headlights, it also has this
customer-programmable feature. When your
headlights are in the automatic mode and the
engine is running, they will automatically turn
on when the wiper system is on. This feature is
programmable through the Uconnect system
Ú page 237.
If your vehicle is equipped with the Rain Sensing
Wiper system Ú page 59, and it is activated,
the headlights will automatically turn on after
the wipers complete five wipe cycles within
approximately one minute, and they will turn off
approximately four minutes after the wipers
completely stop.
NOTE:
When your headlights come on during the
daytime, the instrument panel lights will auto -
matically dim to the lower nighttime intensity.

STARTING AND OPERATING151
ENGINE BREAK-IN RECOMMENDATIONS —
DIESEL ENGINE
The diesel engine does not require a break-in
period due to its construction. Normal operation
is allowed, providing the following
recommendations are followed:
Warm up the engine before placing it under
load.
Do not operate the engine at idle for
prolonged periods.
Observe vehicle oil pressure and tempera -
ture indicators.
Check the coolant and oil levels frequently.
Vary throttle position at highway speeds
when carrying or towing significant weight.
NOTE:
Light duty operation such as light trailer towing
or no load operation will extend the time before
the engine is at full efficiency. Reduced fuel
economy and power may be seen at this time.
The engine oil installed in the engine at the
factory is a high-quality energy conserving type
lubricant. Oil changes should be consistent with anticipated climate conditions under which
vehicle operations will occur. For the
recommended viscosity and quality grades
Ú
page 475.
NOTE:
NON-DETERGENT OR STRAIGHT MINERAL OILS
MUST NEVER BE USED.
PARKING BRAKE
ELECTRIC PARK BRAKE (EPB)
Your vehicle is equipped with an EPB that offers
simple operation, and some additional features
that make the parking brake more convenient
and useful.
The parking brake is primarily intended to
prevent the vehicle from rolling while parked.
Before leaving the vehicle, make sure that the
parking brake is applied. Also, be certain to
leave the transmission in PARK.
You can engage the parking brake in two ways:
Manually, by applying the parking brake
switch.
Automatically, by enabling the Auto Park
Brake feature in the customer programmable
features section of the Uconnect settings. The parking brake switch is located on the
instrument panel to the left of the steering
wheel (below the headlamp switch).

Electric Park Brake Switch

To apply the parking brake manually, pull up on
the switch momentarily. You may hear a slight
sound from the back of the vehicle while the
parking brake engages. Once the park brake is
fully engaged, the BRAKE telltale light in the
instrument cluster and an indicator on the
switch will illuminate. If your foot is on the brake
pedal while you apply the parking brake, you
may notice a small amount of brake pedal
movement. The parking brake can be applied
even when the ignition switch is OFF but the
BRAKE telltale light will not illuminate, however,
it can only be released when the ignition is in
the ON/RUN mode.

SAFETY353
eye irritation, rinse the area with cool water.
For nose or throat irritation, move to fresh air.
If the irritation continues, see your doctor. If
these particles settle on your clothing, follow
the garment manufacturer’s instructions for
cleaning.
Do not drive your vehicle after the air bags have
deployed. If you are involved in another
collision, the air bags will not be in place to
protect you.
NOTE:
Air bag covers may not be obvious in the inte -
rior trim, but they will open during air bag
deployment.
After any collision, the vehicle should be
taken to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication
network remains intact, and the power remains
intact, depending on the nature of the event,
the Occupant Restraint Controller (ORC) will
determine whether to have the Enhanced
Accident Response System perform the
following functions:
Cut off fuel to the engine (if equipped)
Cut off battery power to the electric motor (if
equipped)
Flash hazard lights as long as the battery has
power
Turn on the interior lights, which remain on
as long as the battery has power or for
15 minutes from the intervention of the
Enhanced Accident Response System
Unlock the power door locks
Your vehicle may also be designed to perform
any of these other functions in response to the
Enhanced Accident Response System:
Turn off the Fuel Filter Heater, Turn off the
HVAC Blower Motor, Close the HVAC Circula -
tion Door
Cut off battery power to the:
Engine
Electric Motor (if equipped)
Electric power steering
Brake booster
Electric park brake
Automatic transmission gear selector
Horn
Front wiper
Headlamp washer pump
NOTE:
After an accident, remember to cycle the igni -
tion to the STOP (OFF/LOCK) position and
remove the key from the ignition switch to avoid
draining the battery. Carefully check the vehicle
for fuel leaks in the engine compartment and on
the ground near the engine compartment and
fuel tank before resetting the system and
starting the engine. If there are no fuel leaks or
damage to the vehicle electrical devices (e.g.
headlights) after an accident, reset the system
by following the procedure described below. If
you have any doubt, contact an authorized
dealer.
WARNING!
Deployed air bags and seat belt
pretensioners cannot protect you in another
collision. Have the air bags, seat belt
pretensioners, and the seat belt retractor
assemblies replaced by an authorized dealer
immediately. Also, have the Occupant
Restraint Controller System serviced as well.
