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 122.
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.
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.

STARTING AND OPERATING81
4. If the engine fails to start after eight attempts, allow the starter to cool for at least
10 minutes, then repeat the procedure.
IF ENGINE FAILS TO START
If the engine fails to start after you have followed
the “Normal Starting” or “Cold Weather Operation”
procedure, and has not experienced an extended
park condition as identified in “Extended Park
Starting” procedure it may be flooded. Push the
accelerator pedal all the way to the floor and hold
it there. Crank the engine for no more than
10 seconds. This should clear any excess fuel in
case the engine is flooded. Leave the ignition in the
RUN position, release the accelerator pedal and
repeat the “Normal Starting” procedure.
AFTER STARTING — WARMING UP THE
E
NGINE
Proceed as follows:
Travel slowly, letting the engine run at a reduced
RPM, without accelerating suddenly.
It is recommended to wait until the engine
coolant temperature gauge starts to rise for
maximum performance.
STOPPING THE ENGINE
To shut off the engine with vehicle speed greater
than 5 mph (8 km/h), you must push and hold the
ignition or push the ENGINE START/STOP button
three times consecutively within a few seconds.
The engine will shut down, and the ignition will be
placed in the RUN position.
Turning off the car (place the ignition from the RUN
position to the OFF position), the power supply to
the accessories are maintained for a period of
three minutes.
NOTE:If the vehicle fails to shut off using the ignition
Ú page 64.
Opening the driver side door with the ignition in
RUN will sound a short chime that reminds the
driver to place the ignition to OFF.
CAUTION!
To prevent damage to the starter, do not crank
continuously for more than 10 seconds at a
time. Wait 10 to 15 seconds before trying again.
WARNING!
Never pour fuel or other flammable liquid into
the throttle body air inlet opening in an
attempt to start the vehicle. This could result
in flash fire causing serious personal injury.
Do not attempt to push or tow your vehicle to
get it started. Vehicles equipped with an auto -
matic transmission cannot be started this
way. Unburned fuel could enter the catalytic
converter and once the engine has started,
ignite and damage the converter and vehicle.
If the vehicle has a discharged battery,
booster cables may be used to obtain a start
from a booster battery or the battery in
another vehicle. This type of start can be
dangerous if done improperly Ú page 226.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
10 seconds at a time. Wait 10 to 15 seconds
before trying again.

84STARTING AND OPERATING
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 status, some EPB functionalities
may be deactivated. In this event, urgent service of
the EPB system is required. Do not rely on the EPB
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 automatic transmission
is placed in PARK whenever the ignition is in the
OFF position. Auto Park Brake is enabled and
disabled by customer selection through the
Customer Programmable Features section of the
Uconnect Settings.
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
and the ignition is in the RUN position. In some cases, if the ignition is cycled from ON/RUN to OFF
and the gear selector is not firmly locked in the
PARK position, EPB applies automatically even if
Auto Park Brake has been previously disabled.
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 the RUN position.
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 or
accelerator pedal.
The seat belt is unbuckled.
The driver door is open.
The vehicle is not in the PARK position.
SafeHold can be temporarily bypassed by pushing
the EPB switch while the driver 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 cycled to the OFF position and back to RUN
position.
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. 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 ignition is in the ON/RUN position.
The brake pedal not pressed.
While in service mode, the EPB fault lamp will flash
continuously while the ignition is placed in the ON
position.
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.
