Rear Axle Locker Fault Warning Light —
If Equipped
This warning light will illuminate to indicate
when a rear axle locker fault has been
detected.
Service Forward Collision Warning (FCW)
Light — If Equipped
This warning light will illuminate to indicate a
fault in the FCW System. Contact an authorized
dealer for service
Úpage 274.
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.
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. We recommend you drive to the
nearest service center and have the vehicle serviced
immediately.
Cruise Control Fault Warning Light
This warning light will illuminate to indicate the
Cruise Control System is not functioning
properly and service is required. Contact an
authorized dealer.
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 duration 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.
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.
CAUTION!
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.

23_DT_OM_EN_USC_t.book Page 112

GETTING TO KNOW YOUR INSTRUMENT PANEL113
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.YELLOW INDICATOR LIGHTS

warning have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended that you
take your vehicle to an authorized dealer to have your
sensor function checked.

STARTING AND OPERATING135
The vehicle will return to NRH from Aero Mode if the
vehicle speed remains between 30 mph (48 km/h)
and 35 mph (56 km/h) for greater than 20 seconds or
if the vehicle speed falls below 30 mph (48 km/h).
NOTE:
Automatic Aero mode will be disabled if a trailer is
detected to prevent shifting loads.
 Speed thresholds for raising/lowering the vehicle
automatically at higher speeds only apply if
Automatic Aero Mode is enabled in your Uconnect
Radio settings.
To enter Aero Height manually push the height selector
switch down once from NRH at any vehicle speed. To
return to NRH push the height selector switch up once
while vehicle speed is less than 56 mph (90 km/h).
NOTE:Automatic Aero Mode may be disabled through vehicle
settings in the instrument cluster display Úpage 98 or
through your Uconnect Radio (if equipped) Úpage 191.
