Manual Park Release
{Warning
The transmission will be placed in
N (Neutral) when the manual park
release is pulled. The vehicle can
roll and you or others could be
injured. Ensure the vehicle is on
level ground.
Caution
The manual park release is not
intended to be used for towing.
Damage may result from using the

2. Turn the vehicle off.

DRIVING AND OPERATING 191
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
0 118.
ABS does not change the time needed
to get a foot on the brake pedal and
does not always decrease stopping
distance. If you get too close to the
vehicle ahead, there will not be
enough time to apply the brakes if
that vehicle suddenly slows or stops.
Always leave enough room ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold the
brake pedal down firmly. Hearing or
feeling ABS operate is normal.
Braking in Emergencies
ABS allows steering and braking at the
same time. In many emergencies,
steering can help even more than
braking.
Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The EPB can always be
activated, even if the ignition is off. To
prevent draining the battery, avoid
repeated cycles of the EPB system
when the engine is not running. The system has a
Y,f, or PARK
Electric Parking Brake light, and a
8
Service Parking Brake light. See
Electric Parking Brake Light 0118 and
Service Electric Parking Brake Light
0 118.
Before leaving the vehicle, check for
the
Y,f, or PARK light to ensure
that the parking brake is applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Press the EPB switch momentarily.
The
Y,f, or PARK light will flash
and then stay on once the EPB is fully
applied. If the
Y,f, or PARK light
flashes continuously, then the EPB is
only partially applied or there is a
problem with the EPB. A DIC message
will display. Release the EPB and try
to apply it again. If the light does not
come on, or keeps flashing, have the
vehicle serviced. Do not drive the

wire colors on the brake controller
may be different from the vehicle. The
electric trailer brake controller should
be installed by your dealer or a
qualified service center.
If equipped, there are four blunt cut
wires inside the front driver side
instrument panel. It will be necessary
to have a technician connect the
12-volt power to the engine
compartment fuse block.Trailer Lamps
Always check all trailer lamps are
working at the beginning of each trip,
and periodically on longer trips.
Turn Signals When Towing a
Trailer
When properly connected, the trailer
turn signals will illuminate to indicate
the vehicle is turning, changing lanes,
or stopping. When towing a trailer,
the arrows on the instrument cluster
will illuminate even if the trailer is not
properly connected or the bulbs are
burned out.
Always check all trailer lamps are
working at the beginning of each trip,
and periodically on longer trips.
Trailer Sway Control (TSC)
Vehicles with StabiliTrak/Electronic
Stability Control (ESC) have a Trailer
Sway Control (TSC) feature. Trailer
sway is unintended side-to-side
motion of a trailer while towing. If the
vehicle is towing a trailer and the TSC
detects that sway is increasing, the
vehicle brakes are selectively applied
at each wheel, to help reduce
excessive trailer sway. If equipped with
the Integrated Trailer Brake Control
(ITBC) system, and the trailer has an
electric brake system, StabiliTrak/ESC
may also apply the trailer brakes.
