GETTING TO KNOW YOUR VEHICLE47
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.

122STARTING AND OPERATING
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or
55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be
detrimental and should be avoided.
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
Úpage 396.
NOTE:A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered a normal part of the break-in and not inter -
preted as a problem. Please check your oil level with the
engine oil indicator often during the break-in period. Add
oil as required.
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 position.
NOTE:The EPB Warning Light will illuminate if the EPB switch is
held for longer than 20 seconds in either the released or
applied position. The light will extinguish upon releasing
the switch.
If the Auto Park Brake feature is enabled, the parking
brake will automatically engage whenever the
transmission is placed into PARK. If your foot is on the
brake pedal, you may notice a small amount of brake
pedal movement while the parking brake is engaging.
The parking brake will release automatically when the
ignition is ON, the transmission is in DRIVE or REVERSE,
the driver seat belt is buckled, and an attempt is made to
drive away.
To release the parking brake manually, the ignition switch
must be in the ON/RUN position. Put your foot on the
brake pedal, then push the parking brake switch down
momentarily. You may hear a slight whirring sound from
the back of the vehicle while the parking brake
disengages.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result.
