WARNING!
•Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Monox-
ide (CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious injury
or death when inhaled.
• Keep key fobs away from children. Operation of the
Remote Start System, windows, door locks or other
controls could cause serious injury or death.
Remote Start Abort Message
The following messages will display in the instrument
cluster display if the vehicle fails to remote start or exits
remote start prematurely:
• Remote Start Cancelled — Door Open
• Remote Start Cancelled — Hood Open
• Remote Start Cancelled — Fuel Low
• Remote Start Cancelled — System Fault
• Remote Start Disabled — Start Vehicle to Reset
The instrument cluster display message stays active until
the ignition is turned to the ON/RUN position.
To Enter Remote Start Mode
Push and release the Remote Start button on the key fob
twice within five seconds. The parking lights will flash,
vehicle doors will lock, and the horn will chirp twice (if
programmed). Once the vehicle has started, the engine will
run for 15 minutes.
NOTE:
• If your power door locks were unlocked, Remote Start
will automatically lock the doors.
• If an engine fault is present or fuel level is low, the
vehicle will start and then shut down in 10 seconds.
• The park lamps will turn on and remain on during
Remote Start mode.
• For security, power window and power sunroof opera-
tion (if equipped) are disabled when the vehicle is in the
Remote Start mode.
• The engine can be started two consecutive times (two
15-minute cycles) with the key fob. However, the igni-
tion must be placed in the ON/RUN position before you
can repeat the start sequence for a third cycle.

Wind Buffeting
Wind buffeting can be described as the perception of
pressure on the ears or a helicopter-type sound in the ears.
Your vehicle may exhibit wind buffeting with the windows
down, or the sunroof (if equipped) in certain open or
partially open positions. This is a normal occurrence and
can be minimized. If the buffeting occurs with the rear
windows open, open the front and rear windows together
to minimize the buffeting. If the buffeting occurs with the
sunroof open, adjust the sunroof opening to minimize the
buffeting or open any window.
POWER SUNROOF — IF EQUIPPED
Single Pane Power Sunroof — If Equipped
The power sunroof switches are located on the overhead
console between the courtesy/reading lights.
WARNING!
•Never leave children unattended in a vehicle, or with
access to an unlocked vehicle. Never leave the key
fob in or near the vehicle, or in a location accessible
to children. Do not leave the ignition of a vehicle
equipped with Keyless Enter-N-Go in the ACC or

WARNING!
To avoid serious injury or death:
•Only devices designed for use in this type of outlet
should be inserted into any 12 Volt outlet.
• Do not touch with wet hands.
• Close the lid when not in use and while driving the
vehicle.
• If this outlet is mishandled, it may cause an electric
shock and failure.
CAUTION!
• Many accessories that can be plugged in draw power
from the vehicle’s battery, even when not in use (i.e.,
cellular phones, etc.). Eventually, if plugged in long
enough, the vehicle’s battery will discharge suffi-
ciently to degrade battery life and/or prevent the
engine from starting.
(Continued)
CAUTION! (Continued)
•Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.), will discharge the
battery even more quickly. Only use these intermit-
tently and with greater caution.
• After the use of high power draw accessories, or long
periods of the vehicle not being started (with acces-
sories still plugged in), the vehicle must be driven a
sufficient length of time to allow the generator to
recharge the vehicle’s battery.

After a trip:
•Check if any aftermarket equipment was installed (ad-
ditional lights, upfitter electrical accessories, audio sys-
tems, alarms) and review specifications if any (load and
Ignition Off Draw currents).
• Evaluate the latest driving cycles (distance, driving time
and parking time).
• The vehicle should have service performed if the mes-
sage is still present during consecutive trips and the
evaluation of the vehicle and driving pattern did not
help to identify the cause.
WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the instru-
ment panel together with a dedicated message and/or
acoustic signal when applicable. These indications are
indicative and precautionary and as such must not be
considered as exhaustive and/or alternative to the infor-
mation contained in the Owner ’s Manual, which you are
advised to read carefully in all cases. Always refer to the
information in this chapter in the event of a failure indica-
tion. All active telltales will display first if applicable. The system check menu may appear different based upon
equipment options and current vehicle status. Some tell-
tales are optional and may not appear.
Red Warning Lights
— Seat Belt Reminder Warning Light
This warning light indicates when the driver or passenger
seat belt is unbuckled. When the ignition is first placed in
the ON/RUN or ACC/ON/RUN position and if the
driver ’s seat belt is unbuckled, a chime will sound and the
light will turn on. When driving, if the driver or front
passenger seat belt remains unbuckled, the Seat Belt Re-
minder Light will flash or remain on continuously and a
chime will sound.
Refer to “Occupant Restraint Systems” in “Safety” for
further information.
— 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 or
ACC/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

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.”
— Air Suspension Fault Warning Light — If
Equipped
This light will illuminate when a fault is detected with the
air suspension system.
— 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 sys-
tems. 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 ve-
hicle 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 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.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the vehicle
control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.
