134GETTING TO KNOW YOUR INSTRUMENT PANEL
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.

DESCRIPTION
The air suspension system provides full-time
load-leveling capability along with the benefit of
being able to adjust vehicle height by using the
toggle switch.

Air Suspension Switch

Off-Road 2 (OR2) (Raises the vehicle approxi-
mately 2 inches [51 mm]) – This position is
intended for off-road use only where maximum
ground clearance is required. To enter OR2,
push the height selector switch up twice from
the NRH position or once from the OR1 position
while vehicle speed is below 20 mph (32 km/h).
While in OR2, if the vehicle speed exceeds
25 mph (40 km/h) the vehicle height will be
automatically lowered to OR1. Off-Road 2 may not be available due to vehicle payload, an
instrument cluster message will be displayed
when this occurs Ú
page 114.
Off-Road 1 (OR1) (Raises the vehicle approxi -
mately 1 inch [26 mm]) – This position should
be the primary position for all off-road driving
until Off-Road 2 (OR2) is needed. A smoother
and more comfortable ride will result. To enter
OR1, push the height selector switch up once
from the NRH position while the vehicle speed is
below 35 mph (56 km/h). When in the OR1
position, if the vehicle speed remains between
40 mph (64 km/h) and 50 mph (80 km/h) for
greater than 20 seconds or if the vehicle speed
exceeds 50 mph (80 km/h), the vehicle will be
automatically lowered to NRH. Off-Road 1 may
not be available due to vehicle payload, an
instrument cluster message will be displayed
when this occurs Ú page 114.
Normal Ride Height (NRH) – This is the standard

166STARTING AND OPERATING
Aero Height (Lowers the vehicle approximately
0.6 inch [15 mm]) – This position provides
improved aerodynamics by lowering the vehicle.
The vehicle will automatically enter Automatic
Aero Mode when the vehicle speed remains
between 62 mph (100 km/h) and 66 mph
(106 km/h) for greater than 20 seconds or if the
vehicle speed exceeds 66 mph (106 km/h). 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
Ú page 114 or through your Uconnect Radio (if
equipped) Ú page 234.
Entry/Exit Height (Lowers the vehicle approxi -
mately 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 Ú page 19. 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 Ú
page 114.
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.

STARTING AND OPERATING167
NOTE: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
