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.

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.

STARTING AND OPERATING169
If the “SERVICE POWER STEERING”
message and a flashing icon are
displayed on the instrument cluster
screen, it indicates that the vehicle
needs to be taken to an authorized dealer for
service. It is likely the vehicle has lost power
steering assistance Ú page 121.
If the “POWER STEERING HOT” message and an
icon are displayed on the instrument cluster
screen, it indicates that extreme steering
maneuvers may have occurred, which caused an
over temperature condition in the power steering
system. You will lose power steering assistance
momentarily until the over temperature condition
no longer exists. Once driving conditions are safe,
pull over and let vehicle idle for a few moments
until the light turns off Ú page 121.
NOTE:
Even if power steering assistance is no longer
operational, it is still possible to steer the
vehicle. Under these conditions there will be a
substantial increase in steering effort, espe -cially at very low vehicle speeds and during
parking maneuvers.
If the condition persists, see an authorized
dealer for service.

The Engine Stop/Start (ESS) function is developed
to reduce fuel consumption. The system will stop
the engine automatically during a vehicle stop if
the required conditions are met. Releasing the
brake pedal or pressing the accelerator pedal will
automatically restart the engine.
ESS vehicles have been upgraded with a
heavy-duty starter, enhanced battery, and other
upgraded engine parts, to handle the additional
engine starts.
NOTE:It is recommended that the Stop/Start system be
disabled during off-road use.
Secondary Battery
Your vehicle may be equipped with a secondary
battery used to power the Stop/Start system and
the 12 Volt vehicle electrical system. The
secondary battery is located behind the wheel well
for the front passenger wheel.

402SERVICING AND MAINTENANCE
Safety
Both underinflation and overinflation affect the
stability of the vehicle and can produce a feeling of
sluggish response or over responsiveness in the
steering.
NOTE:
Unequal tire pressures from side to side may
cause erratic and unpredictable steering
response.
Unequal tire pressure from side to side may
cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause
abnormal wear patterns and reduced tread life,
resulting in the need for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable
ride. Overinflation produces a jarring and
uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on
the driver's side B-pillar or rear edge of the driver's
side door.
At least once a month:
Check and adjust tire pressure with a good
quality pocket-type pressure gauge. Do not
make a visual judgment when determining proper inflation. Tires may look properly inflated
even when they are underinflated.
Inspect tires for signs of tire wear or visible
damage.
Inflation pressures specified on the placard are
always “cold tire inflation pressure”. Cold tire
inflation pressure is defined as the tire pressure
after the vehicle has not been driven for at least
three hours, or driven less than 1 mile (1.6 km)
after sitting for a minimum of three hours. The cold
tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire
sidewall.
Check tire pressures more often if subject to a
wide range of outdoor temperatures, as tire
pressures vary with temperature changes.
Tire pressures change by approximately 1 psi
(7 kPa) per 12°F (7°C) of air temperature change.
Keep this in mind when checking tire pressure
inside a garage, especially in the Winter.WARNING!
Improperly inflated tires are dangerous and
can cause collisions.
Underinflation increases tire flexing and can
result in overheating and tire failure.
Overinflation reduces a tire's ability to cushion
shock. Objects on the road and chuckholes
can cause damage that result in tire failure.
Overinflated or underinflated tires can affect
vehicle handling and can fail suddenly,
resulting in loss of vehicle control.
Unequal tire pressures can cause steering
problems. You could lose control of your
vehicle.
Unequal tire pressures from one side of the
vehicle to the other can cause the vehicle to
drift to the right or left.
Always drive with each tire inflated to the
recommended cold tire inflation pressure.
CAUTION!
After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the valve stem.
