186 GETTING TO KNOW YOUR INSTRUMENT PANEL
Should one or more tires be in the condition mentioned
above, 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 Tire Pressure Monitoring System (TPMS) that illumi-
nates a low tire pressure telltale when one or more of your
tires is significantly under-inflated. 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 under-inflated
tire causes the tire to overheat and can lead to tire failure.
Under-inflation 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 under-inflation has not reached
the level to trigger illumination of the TPMS low tire pres
-
sure telltale.
Your vehicle has also been equipped with a TPMS malfunc -
tion 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 indi -
cator 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
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.

SAFETY 231
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the “Tire Pressure Monitoring System Warning
Light” will no longer flash, and the "SERVICE TPM
SYSTEM" message will no longer display, and a pressure
value will display in place of the dashes. A system fault can
occur due to any of the following:
• Signal interference due to electronic devices or drivingnext to facilities emitting the same radio frequencies as the
Tire Pressure Monitor (TPM) sensors
• Installing aftermarket window tinting that contains mate -
rials that may block radio wave signals
• Accumulation of snow or ice around the wheels or wheel housings
• Using tire chains on the vehicle
• Using wheels/tires not equipped with TPM sensors

A system fault may occur due to an incorrect TPM sensor loca -
tion condition. When a system fault occurs due to an incorrect
TPM sensor location, the “Tire Pressure Monitoring System
(TPMS) Warning Light” will flash on and off for 75 seconds
and then remain on solid. The system fault will also sound a
chime. In addition, the instrument cluster will display a “Tire
Pressure Temporarily Unavailable” message in place of the
tire pressure display screen. If the ignition switch is cycled, this sequence will repeat, providing the system fault still
exists. If the system fault no longer exists, the “Tire Pressure
Monitoring System Warning Light” will no longer flash and
the tire pressure display screen will be displayed showing the
tire pressure values the correct locations.

Vehicles With Non Matching Full Size Spare Or Compact
Spare
• The non matching full size spare or compact spare tire
does not have a TPM sensor. Therefore, the TPMS will not
monitor the pressure in the non matching full size spare or
compact spare tire.
• If you install the non matching full size spare or compact spare tire in place of a road tire that has a pressure below
the low-pressure warning limit, upon the next ignition
switch cycle, the Tire Pressure Monitoring System (TPMS)
Warning Light and a “LOW TIRE” message will remain
ON and a chime will sound. In addition, the graphic in the
instrument cluster will still display a pressure value in a
different color and an “Inflate to XX” message.
• After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the Tire Pressure Monitoring System
(TPMS) Warning Light will flash on and off for 75 seconds
and then remain on solid. In addition, the instrument

232 SAFETY
cluster will display a "SERVICE TPM SYSTEM" message
for a minimum of five seconds and then display dashes (--)
in place of the pressure value.
• For each subsequent ignition switch cycle, a chime will sound, the Tire Pressure Monitoring System (TPMS)
Warning Light will flash on and off for 75 seconds and
then remain on solid, and the instrument cluster will
display a "SERVICE TPM SYSTEM" message for a
minimum of five seconds and then display dashes (--) in
place of the pressure value.
• Once you repair or replace the original road tire and rein -
stall it on the vehicle in place of the non matching full size
spare or compact spare, the TPMS will update automati -
cally. In addition, the Tire Pressure Monitoring System
(TPMS) Warning Light will turn OFF and the graphic in
the instrument cluster will display a new pressure value
instead of dashes (--), as long as no tire pressure is below
the low-pressure warning limit in any of the four active
road tires. The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in order for the TPMS
to receive this information. Tire Fill Alert
This feature notifies the user when the placard tire pressure
is attained while inflating or deflating the tire.
The customer may choose to disable or enable the Tire Fill
Alert feature through use of the customer settings in the
radio.
NOTE:
• Only one tire can be filled at a time when using the Tire Fill
Alert system.
• The Tire Fill Alert feature cannot be entered if an existing TPM system fault is set to “active” or if the system is in
deactivation mode (if equipped).
The system will be activated when a positive increase in tire
pressure is detected by the TPM system while inflating the
tire. The ignition must be in the RUN mode, with the trans -
mission in PARK (P).
NOTE:
It is not required to have the engine running to enter Tire Fill
Alert mode.

Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts and
cracks. Inspect sidewalls for cuts, cracks, and bulges. Check
the wheel bolts for tightness. Check the tires (including
spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline fumes
are detected or if fuel, or brake fluid leaks are suspected, the
cause should be located and corrected immediately.

STARTING AND OPERATING 321
33 mph (53 km/h). Once the vehicle speed goes below15 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/Exitchange will be cancelled. 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).
Entry/Exit mode may not be available due to vehicle
payload, an instrument cluster message will be displayed
when this occurs. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for further
information.
NOTE:
Entry/Exit mode may be achieved using your key fob for
easier entry/loading. Refer to “Keys” in “Getting To Know
Your Vehicle” for further information. 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. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for further infor
-
mation.
CAUTION!
When in ENTRY/EXIT setting, be aware of your
surroundings, you may not have the clearance required
for certain areas and vehicle damage may occur.
