Security System Manual Override
The vehicle security alarm will not arm/disarm if you lock/
unlock the doors using the manual door lock plunger.
DOORS
Manual Door Locks
Front and rear doors may be locked by moving the lock knob
down. The lock knobs will unlock when the interior handle
is used to open the doors.Door Lock Knob Front doors may be opened with the inside door handle
without lifting the lock knob.
Doors locked before closing will remain locked when closed.
The emergency key will unlock the driver door lock on your
vehicle.WARNING!
• Do not leave children or animals inside parked vehicles in hot weather. Interior heat build-up may cause
serious injury or death.
• For personal security and safety in the event of an colli -
sion, lock the vehicle doors as you drive as well as
when you park and leave the vehicle.
• Before exiting a vehicle, always shift the automatic transmission into PARK, apply the parking brake, turn
the vehicle OFF, remove the key fobs from vehicle, and
lock all doors. and lock your vehicle.
• Never leave children alone in a vehicle, or with access to an unlocked vehicle. Leaving children in a vehicle
unattended 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.

GETTING TO KNOW YOUR VEHICLE 67
Daytime Running Lights (DRL) — If Equipped
The headlights on your vehicle will illuminate when the
engine is started and the transmission is in any gear except
PARK. This provides a constant "lights on" condition until
the ignition is turned OFF. The lights illuminate at less than
half of normal intensity. If the parking brake is applied, the
Daytime Running Lights (DRL) 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 acti-
vation. Once the turn signal is no longer active, the DRL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 instrument panel to
switch the headlights to high beam. Pulling the multifunc -
tion 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. 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 informa -
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 improperly.

150 GETTING TO KNOW YOUR INSTRUMENT PANEL
— 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.
Yellow Warning Lights
— Adaptive Cruise Control (ACC) Fault Warning Light
— If Equipped
This warning light will illuminate to indicate a fault in the
ACC system. Contact a local authorized dealer for service.
For further information, refer to “Adaptive Cruise Control
(ACC)” in “Starting And Operating.”
— Engine Check/Malfunction Indicator Warning Light
(MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a
part of an Onboard Diagnostic System called OBD II that
monitors engine and automatic transmission control
systems. This warning light will illuminate when the ignition
is in the ON/RUN position before engine start. If the bulb does not come on when turning the ignition switch from OFF
to ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap, poor
quality fuel, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through
several typical driving styles. In most situations, the vehicle
will drive normally and will not require towing.
When the engine is running, the MIL may flash to alert
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced by an authorized dealer as soon as
possible if this occurs.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you drive
slowly or park over flammable substances such as dry
plants, wood, cardboard, etc. This could result in death
or serious injury to the driver, occupants or others.

212 SAFETY
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 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 thebattery 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 Circulation 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 ignition 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.

STARTING AND OPERATING 245
Automatic Transmission

Gear ” will display in the instrument cluster.
NOTE:
In some cases the ParkSense graphic will be displayed in the
instrument cluster, causing the “ AutoPark Engaged Shift to
P then Shift to Gear ” to not be seen. In these cases, the shifter
must be returned to “P” to select desired gear.

STARTING AND OPERATING 249
If the driver shifts into PARK while moving, the vehicle
may AutoPark.
AutoPark will engage ONLYwhen vehicle speed is 1.2 MPH
(1.9 km/h) or less.
The MESSAGE “ Vehicle Speed is Too High to Shift to
P ”will be displayed in the instrument cluster if vehicle speed
is above 1.2 MPH (1.9 km/h).
4WD LOW — If Equipped
AutoPark will be disabled when operating the vehicle in
4WD LOW.
The MESSAGE “ AutoPark Disabled ” will be displayed in
the instrument cluster. Additional customer warnings will be given when all of
these conditions are met:
• Vehicle is not in PARK
• Driver’s Door is ajar
• Vehicle is in 4WD LOW range
The MESSAGE “
AutoPark Not Engaged ” will be displayed
in the instrument cluster. A warning chime will continue
until you shift the vehicle into PARK or the Driver’s Door is
closed.
ALWAYS DO A VISUAL CHECK
that your vehicle is in
PARK by looking for the "P" in the Instrument Cluster
Display and near the shifter. As an added precaution, always
apply the parking brake when exiting the vehicle.
If Engine Fails To Start
If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push the
accelerator pedal all the way to the floor and hold it there
while the engine is cranking. This should clear any excess
fuel in case the engine is flooded.

transmission will default to NEUTRAL until the vehicle
speed drops below 1.2 MPH (1.9 km). A vehicle left in
the NEUTRAL position can roll. As an added precaution,
always apply the parking brake when exiting the
vehicle.
