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 park brake must be unapplied.
• The transmission must be in PARK or NEUTRAL.
While in service mode, the Electric Park Brake fault lamp will
flash continuously while the ignition is ON.

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 Electric Park Brake Switch.AUTOMATIC TRANSMISSION
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 position as a substitute for the parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle move -
ment 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 transmission gear
selector out of PARK with the brake pedal released. Make
sure the transmission is in PARK before exiting the vehicle.

• The transmission may not engage PARK if the vehicle is moving. Always bring the vehicle to a complete stop
before shifting to PARK, and verify that the transmission
gear position indicator solidly indicates PARK (P) without
blinking. Ensure that the vehicle is completely stopped,
and the PARK position is properly indicated, before
exiting the vehicle.

• It is dangerous to shift out of PARK or NEUTRAL 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 headlights from incorrectly shining into oncoming
traffic. When raising the vehicle, the rear of the vehicle will
move up first and then the front. When lowering the vehicle,
the front will move down first and then the rear.
After the engine is turned off, it may be noticed that the air
suspension system operates briefly, this is normal. The
system is correcting the position of the vehicle to ensure a
proper appearance.CAUTION!
