REMOTE START — IF EQUIPPED (DIESEL)
This system uses the key fob to start the
engine conveniently from outside the
vehicle while still maintaining security.
The system has a range of approximately
328 ft (100 m).
Remote Start is used to defrost windows in cold
weather, and to reach a comfortable climate in all
ambient conditions before the driver enters the
vehicle.
NOTE:
The vehicle must be equipped with an auto -
matic transmission to be equipped with Remote
Start.
Obstructions between the vehicle and the key
fob may reduce this range.
The Remote Start system will wait for the Wait
To Start yellow telltale to extinguish before
cranking the engine Ú page 132. This allows
time for the engine preheat cycle to heat the
cylinder air, and is normal in cold weather.
HOW TO USE REMOTE START
Push and release the Remote Start button on the
key fob twice within five seconds. The vehicle
doors and tailgate will lock, the turn signals will
flash twice, and the horn will chirp twice. Pushing
the Remote Start button again will shut the engine
off.
NOTE:
With Remote Start, the engine will only run for
15 minutes.
Remote Start can only be used twice.
If an engine fault is present or fuel level is low,
the vehicle will start and then shut down in 10
seconds.
WARNING!
Do not start or run an engine in a closed
garage or confined area. Exhaust gas contains
carbon monoxide (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.

FUEL SYSTEM MESSAGES
The following chart contains a list of different messages that may appear in the instrument cluster, depending on different system or fuel conditions. Use the
descriptions to interpret what the message means and determine the best action to take.
MESSAGE DESCRIPTION
Diesel Emissions Additive AdBlue® (UREA) Warning Messages:
Low Diesel Emissions Additive AdBlue® (UREA) Level
Warning The first low level warning will be given at around a 1,490 miles (2,400 km) range, and is
determined according to the current consumption rate. The “UREA Low Level” warning light
and message will display on the instrument panel. The UREA low level warning light will
remain lit until the AdBlue® (UREA) tank is topped up with at least 1.32 gallons (5 Liters) of
UREA.
If the level is not resolved, an additional warning appears whenever a certain threshold is
reached until it will no longer be possible to start the engine.
When 125 miles (200 km) are remaining before the AdBlue® (UREA) tank is empty, a
message will appear on the instrument panel, accompanied by a buzzer sound. When the
range is at 0, the display will show a dedicated message (if equipped). In this case, the
engine will not restart.

It will be possible to restart the engine again as soon as AdBlue® (UREA) is added; the
minimum amount required is 1.32 gallons (5 Liters). Fill the AdBlue® (UREA) tank as soon as
possible with at least 1.32 gallons (5 Liters) of UREA. If filling is completed with autonomy tank
AdBlue® (UREA) to zero, it could be possible to wait 2 minutes before starting the vehicle.

NOTE:When the AdBlue® (UREA) tank is empty, and the vehicle is stopped, it is no longer possible
to restart the vehicle until a minimum of 1.32 gallons (5 Liters) of AdBlue® (UREA) is added
to the AdBlue® (UREA) tank.

Electronic Stability Control (ESC) OFF
Warning Light — If Equipped
This warning light indicates the Electronic
Stability Control (ESC) is off.
Each time the ignition is turned to ON/RUN or ACC/
ON/RUN, the ESC system will be on, even if it was
turned off previously.
Loose Fuel Filler Cap Warning Light —
If Equipped
This warning light will illuminate when the
fuel filler cap is loose. Properly close the
filler cap to disengage the light. If the
light does not turn off, please see an
authorized dealer.
Low Fuel Warning Light
When the fuel level reaches
approximately 2.0 gal (7.5 L), this light
will turn on and a chime will sound. The
light will remain on until fuel is added.
Low Washer Fluid Warning Light —
If Equipped
This warning light will illuminate when the
windshield washer fluid is low
Ú page 364.
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.
Service 4WD Warning Light — If Equipped
This warning light will illuminate to signal
a fault with the 4WD system. If the light
stays on or comes on during driving, it
means that the 4WD system is not
functioning properly and that service is required. It
is recommend you drive to the nearest service
center and have the vehicle serviced immediately.
WARNING!
A malfunctioning catalytic converter, as
previously referenced, 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.

Service Forward Collision Warning (FCW)
Light — If Equipped
This warning light will illuminate to
indicate a fault in the Forward Collision
Warning System. Contact an authorized
dealer for service Úpage 291.
Service Stop/Start System Warning Light —
If Equipped
This warning light will illuminate when the
Stop/Start system is not functioning
properly and service is required. Contact
an authorized dealer for service.
Sway Bar Fault Warning Light —
If Equipped
This light will illuminate when there is a
fault in the sway bar disconnect system
Úpage 166.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a
message is displayed to indicate that the
tire pressure is lower than the
recommended value and/or that slow
pressure loss is occurring. In these cases, optimal
tire life and fuel consumption may not be
guaranteed. Should one or more tires be in the condition
previously mentioned, the display will show the
indications corresponding to each tire.
Each tire, including the spare (if provided), should
be checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
inflation pressure label. If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure
for those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire
pressure telltale when one or more of your tires is
significantly underinflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible and
inflate them to the proper pressure. Driving on a
significantly underinflated tire causes the tire to
overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if underinflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system
is not operating properly. The TPMS malfunction
indicator is combined with the low tire pressure
telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute
and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When
the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
WARNING!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop the
vehicle, avoiding sharp braking and steering. If a
tire puncture occurs, repair immediately using
the dedicated tire repair kit and contact an
authorized dealer as soon as possible.
