guaranteed.
Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire.
WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher
temperatures than in normal operating
conditions. This can cause a fire if you drive
slowly or park over flammable substances such
as dry plants, wood, cardboard, etc. This could
result in death or serious injury to the driver,
occupants or others.
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.

22_MP_OM_EN_USC_t.book Page 94

GETTING TO KNOW YOUR INSTRUMENT PANEL95
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. 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.
Towing Hook Breakdown Warning Light —
If Equipped
This light illuminates when there is a
failure with the tow hook. Contact an
authorized dealer for service.
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.

Cruise Control Ready Indicator Light —
If Equipped With Base Instrument Cluster
This light will turn on when the Cruise
Control has been turned on, but not set
Úpage 117.
ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated
Onboard Diagnostic system called OBD II. This
system monitors the performance of the
emissions, engine, and automatic transmission
control systems. When these systems are
operating properly, your vehicle will provide
excellent performance and fuel economy, as well
as emissions well within current government
regulations.
If any of these systems require service, the OBD II
system will turn on the Malfunction Indicator Light
(MIL). It will also store diagnostic codes and other
information to assist your service technician in
making repairs. Although your vehicle will usually
be drivable and not need towing, see an authorized
dealer for service as soon as possible.

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
C
YBERSECURITY

Your vehicle is required to have an OBD II and a
connection port to allow access to information
related to the performance of your emissions
controls. Authorized service technicians may need
to access this information to assist with the
diagnosis and service of your vehicle and
emissions system Ú page 164.
CAUTION!
Prolonged driving with the MIL on could cause
further damage to the emission control
system. It could also affect fuel economy and
driveability. The vehicle must be serviced
before any emissions tests can be performed.
If the MIL is flashing while the vehicle is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
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.

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 above 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.

in the instrument cluster and the LED indicator on
the switch will extinguish.
NOTE:When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill grade
and away from the curb on an uphill grade. Apply
the parking brake before placing the gear selector
in PARK, otherwise the load on the transmission
locking mechanism may make it difficult to move
the gear selector out of PARK. The parking brake
should always be applied whenever the driver is
not in the vehicle.
If exceptional circumstances should make it
necessary to engage the parking brake while the
vehicle is in motion, maintain upward pressure on
the EPB switch for as long as engagement is
desired. The BRAKE warning lamp will illuminate,
and a continuous chime will sound. The rear stop
lamps will also be illuminated automatically while
the vehicle remains in motion.
To disengage the parking brake while the vehicle is
in motion, release the switch. If the vehicle is
brought to a complete stop using the parking
brake, when the vehicle reaches approximately
3 mph, (5 km/h) the parking brake will remain
engaged.
WARNING!
Do not rely on the parking brake to operate
effectively if the rear brakes have been
immersed in water or mud.
Never use the PARK position as a substitute
for the parking brake. Always apply the
parking brake fully when parked to guard
against vehicle movement and possible injury
or damage.
When leaving the vehicle, always remove the
key fob from the ignition and lock your vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing chil
-
dren to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the gear
selector.
Do not leave the key fob in or near the vehicle,
or in a location accessible to children, and do
not leave the ignition of a vehicle equipped
with Keyless Enter ’n Go™ in the ACC or ON/
RUN position. A child could operate power
windows, other controls, or move the vehicle.
Be sure the parking brake is fully disengaged
before driving; failure to do so can lead to
brake failure and a collision.
Always fully apply the parking brake when
leaving your vehicle, or it may roll and cause
damage or injury. Also be certain to leave the
transmission in PARK. Failure to do so may
allow the vehicle to roll and cause damage or
injury.
WARNING!CAUTION!
If the Brake System Warning Light remains on
with the parking brake released, a brake system
malfunction is indicated. Have the brake system
serviced by an authorized dealer immediately.
WARNING!
Driving the vehicle with the parking brake
engaged, or repeated use of the parking brake
to slow the vehicle, may cause serious damage
to the brake system. Be sure the parking brake
is fully disengaged before driving; failure to do
so can lead to brake failure and a collision.

22_MP_OM_EN_USC_t.book Page 104

STARTING AND OPERATING105
In the unlikely event of a malfunction of the EPB
system, a yellow EPB fault lamp will illuminate. This
may be accompanied by the Brake Warning Light
flashing. In this event, urgent service of the EPB
system is required. Do not rely on the parking
brake to hold the vehicle stationary.
Auto Park Brake
The EPB can be programmed to be applied
automatically whenever the vehicle speed is below
1.9 mph (3 km/h) and the transmission is placed
in PARK. Auto Park Brake is enabled and disabled
by customer selection through the Customer

SafeHold
SafeHold is a safety feature of the EPB system that
will engage the parking brake automatically if the
vehicle is left unsecured while the ignition switch is
in ON/RUN. For automatic transmissions, the EPB will
automatically engage if all of the following
conditions are met:
Vehicle speed is below 1.9 mph (3 km/h).
There is no attempt to press the brake pedal
and accelerator pedal.
The seat belt is unbuckled.
The driver’s door is open.
The vehicle is not in the PARK position.
SafeHold can be temporarily bypassed by pushing
the EPB switch while the driver’s door is open and
the brake pedal is pressed. 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/RUN
again.
Auto Hold — If Equipped
Auto Hold 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. Auto Hold can be activated or deactivated by

Brake Service 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 Service 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. The actuator retraction can be done
easily by entering the Brake Service 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.
Service Mode has requirements that must be met
in order to be activated:
The vehicle must be at a standstill.
The parking brake must be disabled.
The transmission must be in PARK or NEUTRAL.
The EPB switch not activated.
The vehicle in ignition ON/RUN position.
The brake pedal not pressed.While in Service Mode, the EPB fault lamp will flash
continuously while the ignition switch is ON/RUN.
NOTE:A dedicated message will appear in the instrument
cluster display if Brake Service Mode cannot be
activated.
When brake service work is complete, the following
steps must be followed to reset the parking brake
system to normal operation:
Ensure the vehicle is at a standstill.
Press the brake pedal with moderate force.
Apply the EPB Switch.

WARNING!
You can be badly injured working on or around a
motor vehicle. Do only that service work for
which you have the knowledge and the right
equipment. If you have any doubt about your
ability to perform a service job, take your vehicle
to a competent mechanic.
WARNING!
Never use the PARK (P) position as a substi
-
tute for the parking brake. Always apply the
parking brake fully when exiting the vehicle to
guard against vehicle movement and possible
injury or damage.
Your vehicle could move and injure you and
others if it is not in PARK. Check by trying to
move the gear selector out of PARK with the
brake pedal released. Make sure the trans -
mission is in PARK before exiting the vehicle.
It is dangerous to shift out of PARK or
NEUTRAL (N) if the engine speed is higher
than idle speed. If your foot is not firmly
pressing the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and your
foot is firmly pressing the brake pedal.
The vehicle may not engage a newly selected
gear when shifting between PARK, REVERSE
(R), or DRIVE (D) if the vehicle is moving while
shifting.
