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.

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.

EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal requirement to
pass an inspection of your vehicle's emissions
control system. Failure to pass could prevent
vehicle registration. For states that require an Inspection and
Maintenance (I/M), this check verifies
the Malfunction Indicator Light (MIL) is
functioning and is not on when the
engine is running, and that the OBD II system is
ready for testing.
Normally, the OBD II system will be ready. The
OBD II system may not be ready if your vehicle was
recently serviced, recently had a depleted battery
or a battery replacement. If the OBD II system
should be determined not ready for the I/M test,
your vehicle may fail the test.
Your vehicle has a simple ignition actuated test,
which you can use prior to going to the test station.
To check if your vehicle's OBD II system is ready,
you must do the following:

1. Cycle the ignition switch to the ON position, but do not crank or start the engine.

NOTE:If you crank or start the engine, you will have to
start this test over.
2. As soon as you cycle the ignition switch to the ON position, you will see the Malfunction
Indicator Light (MIL) symbol come on as part of
a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen:
The MIL will flash for about 10 seconds and
then return to being fully illuminated until
you turn OFF the ignition or start the engine.
This means that your vehicle's OBD II
system is not ready and you should not
proceed to the I/M station.
The MIL will not flash at all and will remain
fully illuminated until you place the ignition
in the off position or start the engine. This
means that your vehicle's OBD II system is
ready and you can proceed to the I/M
station.
If your OBD II system is not ready, you should see
an authorized dealer or repair facility. If your
vehicle was recently serviced or had a battery
failure or replacement, you may need to do nothing
more than drive your vehicle as you normally would
in order for your OBD II system to update. A
recheck with the previously mentioned test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle's OBD II system
is ready or not, if the MIL is illuminated during
normal vehicle operation you should have your
vehicle serviced before going to the I/M station.
The I/M station can fail your vehicle because the
MIL is on with the engine running.
WARNING!
ONLY an authorized service technician should
connect equipment to the OBD II connection
port in order to read the VIN, diagnose, or
service your vehicle.
If unauthorized equipment is connected to the
OBD II connection port, such as a
driver-behavior tracking device, it may:
Be possible that vehicle systems,
including safety related systems, could be
impaired or a loss of vehicle control could
occur that may result in an accident
involving serious injury or death.
Access, or allow others to access, infor -
mation stored in your vehicle systems,
including personal information.

STARTING AND OPERATING125
AUTO PARK BRAKE
The EPB can be programmed to be applied
automatically whenever the vehicle is at a
standstill and the transmission is placed in PARK.
Auto Park Brake is enabled and disabled by
customer selection through the customer
programmable features section of the Uconnect
Settings Úpage 218.
Any single Auto Park Brake application can be
bypassed by pushing the EPB switch to the release
position while the transmission is placed in PARK.
SAFEHOLD
SafeHold is a safety feature of the EPB system that
will place the transmission in PARK, and engage
the parking brake automatically if the vehicle is left
unsecured while the ignition is in ON/RUN.
The parking brake will automatically engage if all of
the following conditions are met:
The vehicle is at a standstill.
There is no attempt to press the brake pedal or
accelerator pedal.
The seat belt is unbuckled.
The driver door is open. SafeHold can be temporarily bypassed by pushing
the EPB switch while the driver door is open. Once
manually bypassed, SafeHold will be enabled
again once the vehicle reaches 12 mph (20 km/h)
or the ignition is turned to the OFF position and
back to ON again.
HOLD ‘N GO — IF EQUIPPED
Hold ‘N Go is a comfort feature that allows the
driver to remove their foot from the brake pedal
once the vehicle has come to a stop. The vehicle
must be held at a standstill for a predetermined
amount of time by hydraulic braking. The EPB will
then engage and continue to hold the vehicle at a
stop until the driver applies the accelerator pedal.
Hold ‘N Go can be activated or deactivated by
pushing the HOLD button located on the switch
bank.

HOLD Switch
The following conditions must be met for Hold ‘N
Go to activate:
Driver’s door is closed
Driver's seat belt is fastened
Vehicle is at a standstill
Forward gear is selected
ACC is not engaged
EPB is not applied
ParkSense Active Park Assist System auto
parking maneuver is not activated
BRAKE MAINTENANCE MODE
We recommend having your brakes serviced by an
authorized dealer. You should only make repairs
for which you have the knowledge and the right
equipment. You should only enter Brake
Maintenance Mode during brake service.
When servicing your rear brakes, it may be
necessary for you or your technician to push the
rear piston into the rear caliper bore. With the EPB
system, this can only be done after retracting the
EPB actuator. Fortunately, actuator retraction can
be done easily by entering the Brake Maintenance
Mode through the Uconnect Settings in your
vehicle. This menu-based system will guide you
through the steps necessary to retract the EPB
actuator in order to perform rear brake service.
