74GETTING TO KNOW YOUR INSTRUMENT PANEL
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
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine
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 133.

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.
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.
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.

80STARTING AND OPERATING
In the unlikely event of a malfunction of the EPB
system, a yellow EPB Warning Light 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 Electric Park Brake (EPB) can be programmed
to be applied automatically whenever the vehicle is
at a standstill and the automatic 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 Ú page 145.
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 Electric Park
Brake (EPB) system that will 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
and accelerator pedal.
The occupant status changed to unoccupied.
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.
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 Electric Park Brake (EPB) system, this can
only be done after retracting the EPB actuator.
Fortunately, 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 unapplied.
The transmission must be in PARK or NEUTRAL.
While in Service Mode, the EPB Warning Light will
flash continuously while the ignition is in ON/RUN.
When brake service work is complete, the following
steps must be followed to reset the park brake
system to normal operation:
Ensure the vehicle is at a standstill.
Press the brake pedal with moderate force.
Apply the EPB Switch.
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.
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.
