PARKING BRAKE
Electric Park Brake (EPB)
Your vehicle is equipped with a new Electric
Park Brake System (EPB) that offers greater
convenience. The park brake switch is
located in the center console.Park Brake Switch
To apply the park brake manually, pull up on
the switch momentarily. The BRAKE telltale
light in the instrument cluster and an indi -
cator on the switch will illuminate. To release the park brake manually, the igni
-
tion must be in ON/RUN. Then put your foot
on the brake pedal and push the park brake
switch down momentarily. Once the park
brake is fully disengaged, the BRAKE telltale
light and the switch indicator will extinguish.
The park brake can also be automatically
released. With the engine running and the
transmission in gear, release the brake pedal
and depress the throttle pedal. For safety
reasons, your seat belt must also be
fastened.
NOTE:
You may hear a slight whirring sound from
the back of the vehicle while the parking
brake engages or disengages.
If your foot is on the brake pedal while you
are engaging or disengaging the parking
brake, you may notice a small amount of
brake pedal movement.
The Auto Park Brake feature can be used
to apply the park brake automatically
every time you park the vehicle. Auto Park
Brake can be enabled and disabled in the
Settings menu in Uconnect.
The parking brake can be engaged even
when the ignition is OFF, however, it can
only be disengaged when the ignition is in
the ON/RUN mode.
SafeHold is a feature that will automati -
cally apply the park brake under certain
conditions. The EPB monitors the status
of the driver’s seat belt, driver’s door and
pedal positions to determine if the driver
may have exited while the vehicle is still
capable of moving and will then automati -
cally apply the park brake to prevent the
vehicle from rolling.
The EPB fault light will illuminate if the
EPB switch is held for longer than 90
seconds in either the released or applied
position. The light will extinguish upon
releasing the switch.

SafeHold
SafeHold is a safety feature of the Electric
Park Brake System that will engage the park
brake automatically if the vehicle is left
unsecured while the ignition is in ON/RUN.
For automatic transmissions, the park brake
will automatically engage if all of the
following conditions are met:
The vehicle is at a standstill.
There is no attempt to depress the brake
pedal or accelerator pedal.
The seat belt is unbuckled.
The driver door is open.
For manual transmissions, the park brake
will automatically engage if all of the
following conditions are met:
The vehicle is at a standstill.
There is no attempt to depress the brake
pedal or accelerator pedal.
The clutch pedal is not pressed.
The seat belt is unbuckled.
The driver door is open.
MANUAL TRANSMISSION —
IF EQUIPPED NOTE:
During cold weather, you may experience
increased effort in shifting until the trans -
mission fluid warms up. This is normal.
Shifting
Fully press the clutch pedal before shifting
gears. As you release the clutch pedal, lightly
press the accelerator pedal.
You should always use FIRST gear when
starting from a standing position.
WARNING!
You or others could be injured if you leave
the vehicle unattended without having the
parking brake fully applied. The parking
brake should always be applied when the
driver is not in the vehicle, especially on
an incline.
CAUTION!
Never drive with your foot resting on the
clutch pedal, or attempt to hold the
vehicle on a hill with the clutch pedal
partially engaged, as this will cause
abnormal wear on the clutch.
Do not drive with your hand resting on
the gear selector as the force exerted,
even if slight, could lead over time to
premature wear of the gearbox internal
components.

stop the engine automatically during a
vehicle stop if the required conditions are
met. Releasing the brake pedal or pressing
the accelerator pedal will automatically
restart the engine.
This vehicle has been upgraded with a heavy
duty battery, starter, as well as other engine
parts, to handle the additional engine starts.
Automatic Mode
The Stop/Start feature is enabled after every
normal customer engine start. At that time,
the system will go into STOP/START READY
and if all other conditions are met, can go
into a STOP/START AUTOSTOP ACTIVE
“Autostop” mode.
To Activate The Autostop Mode, The Following
Must Occur:
The system must be in STOP/START
READY state. A STOP/START READY
message will be displayed in the instru -
ment cluster display within the Stop/Start
section. Refer to “Warning Lights And
Messages” in “Getting To Know Your
Instrument Panel” in your Owner’s
Manual.
The vehicle must be completely stopped.
The gear selector must be in a forward
gear and the brake pedal depressed.
The engine will shut down, the tachometer
will move to the zero position and the Stop/
Start telltale will illuminate indicating you
are in Autostop. Customer settings will be
maintained upon return to an engine running
condition. Refer to the “Stop/Start System” in the
“Starting And Operating” in your Owner’s
Manual.
Possible Reasons The Engine Does Not
Autostop
Prior to engine shut down, the system will
check many safety and comfort conditions to
