254 Driving and Operating
systems will operate as they
do in ON/RUN, but the vehicle
will not be able to be driven.
The engine will not start in
Service Mode. Press ENGINE
START/STOP again to turn
the vehicle off.
Starting the Engine
Place the transmission in the
proper gear, P (Park) or
N (Neutral). To restart the
engine when the vehicle is
already moving, use
N (Neutral).
Caution
Do not try to shift to P (Park)
if the vehicle is moving.
If you do, you could damage
the transmission. Shift to
P (Park) only when the
vehicle is stopped.
Caution
If you add electrical parts or
accessories, you could
change the way the engine
operates. Any resulting
damage would not be
covered by the vehicle
warranty. See Add-On
Electrical Equipment0336.
To start the vehicle: 1. With the Keyless Access system, the remote key
must be in the vehicle.
Press ENGINE START/
STOP with the brake pedal
applied. When the engine
begins cranking, let go of
the button. The idle speed
will go down as the engine
warms up. Do not race the
engine immediately after
starting it.
If the remote key is not in
the vehicle, if there is
interference, or if the
remote key battery is low,
a Driver Information Center (DIC) message will
display. See Remote Key
Operation
09.
Caution
Cranking the engine for long
periods of time, by pressing
ENGINE START/STOP
immediately after cranking
has ended, can overheat and
damage the cranking motor,
and drain the battery. Wait
at least 15 seconds between
each try, to let the cranking
motor cool down.
2. If the engine does not start after five to 10 seconds,
especially in very cold
weather (below −18 °C or
0 °F), it could be flooded
with too much gasoline.
Try pushing the
accelerator pedal all the
way to the floor and hold it
there, then press ENGINE
START/STOP for up to a
maximum of 15 seconds.
Wait at least 15 seconds
between each try, to allow

the cranking motor to cool
down. When the engine
starts, let go of the button
and the accelerator. If the
vehicle starts briefly but
then stops again, do the
same thing. This clears the
extra gasoline from the
engine. Do not race the
engine immediately after
starting it. Operate the
engine and transmission
gently until the oil warms
up and lubricates all
moving parts.
Stop/Start System
The Stop/Start system will
shut off the engine to help
conserve fuel. It has
components designed for the
increased number of starts.
{Warning
The automatic engine Stop/
Start feature causes the
engine to shut off while the
vehicle is still on. Do not exit(Continued)
Warning (Continued)
the vehicle before shifting to
P (Park). The vehicle may
restart and move
unexpectedly. Always shift
to P (Park), and then turn
the ignition off before
exiting the vehicle.
Auto Engine Stop/Start
When the brakes are applied
and the vehicle is at a
complete stop, the engine may
turn off. When stopped, the
tachometer displays AUTO
STOP. See Tachometer 0125.
When the brake pedal is
released or the accelerator
pedal is pressed, the engine
will restart.
To maintain vehicle
performance, other conditions
may cause the engine to
automatically restart before
the brake pedal is released.
Auto Stops may not occur
and/or Auto Starts may occur
because:
.The climate control settings
require the engine to be
running to cool or heat the
vehicle interior.
.The vehicle battery needs to
charge.
.The vehicle battery has
recently been disconnected.
.Minimum vehicle speed has
not been reached since the
last Auto Stop.
.The accelerator pedal is
pressed.
.The engine or transmission
is not at the required
operating temperature.
.The outside temperature is
not in the required operating
range.
.The vehicle transmission is
shifted out of D (Drive) to
any gear other than P (Park).
.Certain driver modes have
been selected. See Driver
Mode Control 0273.
.The vehicle is on a steep hill
or grade.

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 Electric Parking Brake
(EPB) can always be applied,
even if the vehicle is off. In
case of insufficient electrical
power, the EPB cannot be
applied or released. To
prevent draining the battery,
avoid unnecessary repeated
cycles of the EPB.
The system has a red parking
brake status light and an
amber service parking brake
warning light. See Electric
Parking Brake Light0132 and Service Electric Parking Brake
Light
0132. There are also
parking brake-related Driver
Information Center (DIC)
messages.
Before leaving the vehicle,
check the red parking brake
status 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 red parking brake status
light will flash and then stay on
once the EPB is fully applied.
If the red parking brake status
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

brakes. Do not connect a
trailer's hydraulic brake
system directly to your
vehicle's hydraulic brake
system. If you do, both the
vehicle antilock brakes and
the trailer brakes may not
function, which could result
in a crash.
Trailer Wiring
The trailer wiring harness (if
equipped), with a seven-pin
connector is located at the
rear of the vehicle, and it is
tied to the vehicle's frame.
If the vehicle is not equipped
with a seven-pin trailer
connector, the body harness
has provisions to connect a
trailer harness and a seven-pin
trailer connector which is
available through your dealer.
Use only a round, seven-wire
connector with flat blade
terminals meeting SAE J2863
specifications for proper
electrical connectivity.
The seven-wire harness
contains the following trailer
circuits:Stop/Turn

Refer to the aftermarket

owner's manual to determine
wire color coding of the
electric trailer brake controller.
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 that 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.
Trailer Sway
Control (TSC)
Vehicles with StabiliTrak/
Electronic Stability Control
(ESC) have a Trailer Sway
Control (TSC) feature. Trailersway 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.
If TSC is enabled, the Traction
Control System (TCS)/
StabiliTrak/ESC warning light
will flash on the instrument
cluster. Reduce vehicle speed
by gradually removing your
foot from the accelerator.
If trailer sway continues,

{Warning
The Data Link Connector
(DLC) is used for vehicle

testing. See Malfunction
Indicator Lamp (Check
Engine Light)0129. A device
connected to the DLC —
such as an aftermarket fleet
or driver-behavior tracking
device —may interfere with
vehicle systems. This could
affect vehicle operation and
cause a crash. Such devices
may also access information
stored in the vehicle’s
systems.
Caution
Some electrical equipment
can damage the vehicle or
cause components to not
work and would not be
covered by the vehicle
warranty. Always check with
your dealer before adding
electrical equipment.
Add-on equipment can drain
the vehicle's 12-volt battery,
even if the vehicle is not
operating.
The vehicle has an airbag
system. Before attempting to
add anything electrical to the
vehicle, see Servicing the
Airbag-Equipped Vehicle 079
and Adding Equipment to the
Airbag-Equipped Vehicle 080.
