Oil Change Required

Your vehicle is equipped with an
engine oil change indicator system.
The “Oil Change Required”
message will display in the
instrument cluster display for five seconds after a
single chime has sounded, to indicate the next
scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means
the engine oil change interval may fluctuate,
dependent upon your personal driving style.

Unless reset, this message will continue to display
each time the ignition is placed in the ON/RUN
position. To turn off the message temporarily, push
and release the OK or arrow buttons. To reset the
oil change indicator system (after performing the
scheduled maintenance), refer to the following
procedure.

DISPLAY AND MESSAGES
The instrument cluster display is located in the
center portion of the cluster and consist of multiple
sections:
Main Screen — The inner ring of the display will
illuminate in black under normal conditions,
yellow for non critical warnings and red for crit -
ical warnings
Submenu Dots — Whenever there are
submenus available, the position within the
submenus is shown here

Gear Selector Status (PRND)
Driver Interactive Display (Compass, Temp,
Range to Empty, Trip A, Trip B, Average Fuel
Economy, Current Fuel Economy and Time)
Air Suspension Status — If Equipped
Four-Wheel Drive (4WD) Status — If Equipped
The instrument cluster display will normally display
the main menu or the screens of a selected feature
of the main menu. The main display area also
displays pop-up messages and warning or
information messages. These pop-up messages
fall into several categories:
Five Second Stored Messages
When the appropriate conditions occur, this
type of message takes control of the main
display area for five seconds and then returns to
the previous screen. Most of the messages of
this type are then stored (as long as the condi-
tion that activated it remains active) and can be
reviewed from the “Messages” main menu item.
Examples of this message type are “Right Front
Turn Signal Lamp Out” and “Low Tire Pressure”.
Unstored Messages
This message type is displayed indefinitely or
until the condition that activated the message is
cleared. Examples of this message type are
“Turn Signal On” (if a turn signal is left on) and
“Lights On” (if driver leaves the vehicle with the
lights on).

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.

This light will turn on when the ACC is not
operating and needs service
Ú page 142.
Service Forward Collision Warning (FCW)

properly and service is required. Contact
an authorized dealer for service.
Sway Bar Fault Warning Light
This light will illuminate when there is a
fault in the sway bar disconnect system
Úpage 133.
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
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.

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.
YELLOW INDICATOR LIGHTS
4WD Low Indicator Light — If Equipped
This light alerts the driver that the vehicle
is in the 4WD Low mode. The front and
rear driveshafts are mechanically locked
together forcing the front and rear
wheels to rotate at the same speed. Low range
provides a greater gear reduction ratio to provide
increased torque at the wheels Ú page 131.
Air Suspension Active Indicator Light —
If Equipped
This light will illuminate when the air
suspension system is actively adjusting
the ride height Úpage 136.
Air Suspension Aerodynamic Height
Indicator Light— If Equipped
This light will illuminate when the air
suspension system is set to the
Aerodynamic setting Ú page 136.
Air Suspension Entry/Exit Indicator Light—
If Equipped
This light will illuminate when the vehicle
is automatically lowered from ride height
position downward for easy entry and exit
of the vehicle.

Air Suspension Off-Road 1 Indicator Light —
If Equipped

This light will illuminate when the air
suspension system is set to the Off-Road
1 setting Úpage 136.

Air Suspension Off-Road 2 Indicator Light —
If Equipped

This light will illuminate when the air
suspension system is set to the Off-Road
2 setting Úpage 136.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and 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.
