112GETTING TO KNOW YOUR INSTRUMENT PANEL
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.

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.
 Entry/Exit Height (Lowers the vehicle approximately
2 inches [51 mm]) – This position lowers the vehicle
for easier passenger entry and exit as well as lowering
the vehicle for easier loading and unloading of cargo.
To enter Entry/Exit Mode, push the height selector
switch down once from the NRH while the vehicle
speed is below 33 mph (53 km/h). Once the vehicle
speed goes below 15 mph (24 km/h) the vehicle
height will begin to lower. If the vehicle speed remains
between 15 mph (24 km/h) and 25 mph (40 km/h) for
greater than 60 seconds, or the vehicle speed exceeds
25 mph (40 km/h) the Entry/Exit change will be canceled. To return to Normal Height Mode, push the height
selector switch up once while in Entry/Exit or drive the
vehicle over 15 mph (24 km/h).
NOTE:Entry/Exit Height may be achieved using the Remote
Lowering feature on your key fob for easier entry/loading
Úpage 16.
The system requires that the ignition be in the ON/RUN
position or the engine running for all user requested
changes. When lowering the vehicle, all of the doors must
be closed. If a door is opened at any time while the vehicle
is lowering, the change will not be completed until the
open door(s) is closed.
This system uses a lifting and lowering pattern which
keeps the headlights from incorrectly shining into
oncoming traffic. When raising the vehicle, the rear of the
vehicle will move up first and then the front. When
lowering the vehicle, the front will move down first and
then the rear.
After the engine is turned off, it may be noticed that the air
suspension system operates briefly; this is normal. The
system is correcting the position of the vehicle to ensure a
proper appearance.
To assist with changing a spare tire, the air suspension
system has a feature which allows the automatic leveling
to be disabled
Úpage 98. Default Ride Height:

Select Aero Height or Normal Ride Height as the default
for all vehicle speeds and operation. This is the
selected height that the suspension will level for speed
changes (e.g. raising from Entry/Exit Height at speed,
lowering from Off-Road Height at speed, etc.).
 Default ride height can be changed by manually
adjusting the Air Suspension switch to Normal Ride
Height or Aero Ride Height and staying in the selected
height for 2.5 seconds. It will be stored as the default
ride height and the height will be maintained until a
new default ride height is selected.
NOTE:If equipped with a touchscreen radio, all enabling/
disabling of air suspension features must be done through
the radio
Úpage 191.
AIR SUSPENSION MODES
The air suspension system has multiple modes to protect
the system in unique situations. The engine should be
running to change between Air Suspension Modes.
CAUTION!
When in Entry/Exit Height, be aware of your
surroundings, you may not have the clearance required
for certain areas and vehicle damage may occur.
WARNING!
The air suspension system uses a high pressure
volume of air to operate the system. To avoid personal
injury or damage to the system, see an authorized
dealer for service.

STARTING AND OPERATING179
(Continued)
Some trailers (such as boat trailers) will need to
recalibrate while loaded and unloaded.
NOTE:

The system may not detect a trailer in low light condi -
tions. In sunny conditions, the performance may be
degraded as shadows pass over the trailer.
 The driver is always responsible for safe operation of
truck and trailer.
 The driver is always in control of the truck as well as the
trailer and is responsible for controlling the throttle and
brakes.
 The system may not function when the camera lens is
blocked, blurred (covered with water, snow, ice, dirt,
etc) and will not work unless the tailgate is upright and
fully latched.
TOWING REQUIREMENTS
To promote proper break-in of your new vehicle drivetrain
components, the following guidelines are recommended. Perform the maintenance listed in the Scheduled
Servicing section for the proper maintenance intervals
Úpage 333. When towing a trailer, never exceed the
GAWR or GCWR ratings.
Towing Requirements — Tires
 Do not attempt to tow a trailer while using a compact
spare tire.
 Do not drive more than 50 mph (80 km/h) when towing
while using a full size spare tire.
 Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle.
 Check the trailer tires for proper tire inflation pressures
before trailer usage.
 Check for signs of tire wear or visible tire damage
before towing a trailer.
 Replacing tires with a higher load carrying capacity will
not increase the vehicle's GVWR and GAWR limits.
 For further information
Úpage 370.
CAUTION!
Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
 Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps the
engine and other parts of the vehicle wear in at the
heavier loads.
WARNING!
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering cargo
that is not fully secured, dynamic load shifts can
occur that may be difficult for the driver to control.
You could lose control of your vehicle and have a
collision.
 When hauling cargo or towing a trailer, do not over -
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to
brakes, axle, engine, transmission, steering, suspen -
sion, chassis structure or tires.
 Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.
 Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on the
tow vehicle. Put the tow vehicle transmission in
PARK. For four-wheel drive vehicles, make sure the
transfer case is not in NEUTRAL. Always, block or
"chock" the trailer wheels.
 GCWR must not be exceeded.
Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded :
 GVWR
 GTW
 GAWR
 Tongue weight rating for the trailer hitch utilized
