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 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.

122STARTING AND OPERATING
COLD WEATHER OPERATION
(B
ELOW –22°F OR −30°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater
(available from an authorized dealer) is recommended.
AFTER STARTING
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
TURBOCHARGER “COOL DOWN” —
3.0L E
NGINE ONLY
The 3.0L engine is equipped with an after-run pump to
cool the turbocharger after the engine is shut off.
Depending on the type of driving and the amount of cargo,
the pump will run for up to 20 minutes after the engine
has been shut off to circulate coolant through the
turbocharger. Although the pump is rubber-mounted for
quiet operation, it is normal to hear it running during this
time.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a
grounded, three-wire extension cord.
The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine. The engine block heater cord is coiled and strapped right
behind the engine air cleaner filter assembly from the
manufacturer.
ENGINE BREAK-IN RECOMMENDATIONS
An initial break-in period is recommended for the
powertrain (engine, transmission, axle, etc.) in your
vehicle. Adhering to the following guidelines will contribute
to improved longevity, fuel economy, and performance.
Drive moderately during the first 100 miles (160 km).
After that, for the first 500 miles (800 km), avoid long
periods at constant speed. Varying speed, engine RPM,
and throttle position is desirable.
Avoid high performance, severe off-road, and towing for
the first 500 miles (800 km).
NOTE:A new engine may consume some oil during its first few
thousand miles (km) of operation. This should be
considered a normal part of the break-in and not inter -
preted as a problem. For engines not equipped with an oil
level sensor, please check your oil level frequently during
the break-in period. Add manufacturer-approved oil as
required
Úpage 376.
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 EPB switch.
 Automatically, by enabling the Auto Park Brake feature
in the customer programmable features section of the
Uconnect settings.
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result. ONLY USE OILS THAT
ARE API APPROVED

STARTING AND OPERATING159
When the vehicle is in DRIVE, the Side Distance Warning
volume/chime will match the Front ParkSense volume
and chime type.
When the vehicle is in REVERSE, the Side Distance
Warning volume/chime will match the Rear ParkSense
volume and chime type.
NOTE:Parksense will reduce the volume of the radio if on when
the system is sounding an audible tone. An audible tone
will only sound if a collision is possible.
Activation/Deactivation
The system can operate only after driving a short distance
and if the vehicle speed is between 0 and 7 mph
(0 and 11 km/h). The system can be activated/
deactivated via the Settings menu of the Uconnect
system. If the ParkSense System is deactivated via the
ParkSense hard switch then the Side Distance Warning
system will automatically be deactivated.
Message on the display for Side Distance Warning
feature:
“Wipe Sensors” — This message is displayed in the case of
a failure of the Side Distance Warning system sensors.
Free the bumpers of any obstacles, ensure that the front
and rear fascia/bumper are free of snow, ice, mud, dirt
and debris to keep the ParkSense system operating
properly.
“System Not Available” — This message is displayed if the
Side Distance Warning system is not available. The failed
operation of the system might be due to the insufficient
voltage from the battery or other failures on the electrical
system. Contact an authorized dealer as soon as possible
to have the electrical system checked.
ParkSense Usage Precautions
Some conditions may influence the performance of the
Side Distance Warning system:
NOTE:
Ensure that the front and rear fascia/bumper are free
of snow, ice, mud, dirt and debris to keep the Park -
Sense system operating properly.
 Construction equipment, large trucks, and other vibra -
tions could affect the performance of ParkSense.
 When you turn ParkSense off, the message to appear
in the instrument cluster display will read “PARKSENSE
OFF.” Furthermore, once you turn ParkSense off, it
remains off until you turn it on again, even if you cycle
the ignition.
 ParkSense, when on, will reduce the volume of the
radio when it is sounding a tone.
 Clean the ParkSense sensors regularly, taking care not
to scratch or damage them. The sensors must not be
covered with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system not working
properly. The ParkSense system might not detect an
obstacle behind or in front of the fascia/bumper, or it
could provide a false indication that an obstacle is
behind or in front of the fascia/bumper.
 The presence of a tow hook without a trailer may inter -
fere with the correct operation of the parking sensors.
Before using the ParkSense system, it is recom -
mended to remove the removable tow hook ball
assembly and any attachments from the vehicle when
it is not used for towing operations.

264SAFETY
If the passenger seating position is equipped with an ALR
and is being used for normal usage, only pull the seat belt
webbing out far enough to comfortably wrap around the
occupant’s mid-section so as to not activate the ALR. If the
ALR is activated, you will hear a clicking sound as the seat
belt retracts. Allow the webbing to retract completely in
this case and then carefully pull out only the amount of
webbing necessary to comfortably wrap around the
occupant’s mid-section. Slide the latch plate into the
buckle until you hear a "click”.
In Automatic Locking Mode, the shoulder belt is
automatically pre-locked. The seat belt will still retract to
remove any slack in the shoulder belt. Use the Automatic
Locking Mode anytime a child restraint is installed in a
seating position that has a seat belt with this feature.
Children 12 years old and under should always be properly
restrained in the rear seat of a vehicle with a rear seat. How To Engage The Automatic Locking Mode

1. Buckle the combination lap and shoulder belt.

2. Grab the shoulder portion and pull downward until
the entire seat belt is extracted.
3. Allow the seat belt to retract. As the seat belt retracts, you will hear a clicking sound. This indicates the seat
belt is now in the Automatic Locking Mode.
How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt and allow it
to retract completely to disengage the Automatic Locking
Mode and activate the vehicle sensitive (emergency)
locking mode.SUPPLEMENTAL RESTRAINT SYSTEMS
