{Warning
Turning off the vehicle while
moving may cause loss of
power assist in the brake
and steering systems and
disable the airbags. While
driving, only shut the vehicle
off in an emergency.
If the vehicle must be shut off
in an emergency: 1. Brake using a firm and steady pressure. Do not
pump the brakes
repeatedly. This may
deplete power assist,
requiring increased brake
pedal force.
2. Shift the vehicle to N (Neutral). This can be
done while the vehicle is
moving. After shifting to
N (Neutral), firmly apply the
brakes and steer the
vehicle to a safe location.
3. Come to a complete stop and shift to P (Park). 4. Set the parking brake. See
Electric Parking Brake
0269. Press ENGINE
START/STOP to turn the
vehicle off.
If the vehicle cannot be pulled
over and must be shut off
while driving, press and hold
ENGINE START/STOP for
longer than two seconds,
or press twice in five seconds.
Accessory Mode (Amber
Indicator Light) : This mode
allows you to use some
electrical accessories when
the engine is off.
With the ignition off, pressing
the button once without the
brake pedal applied will place
the ignition system in
accessory mode.
The ignition will switch from
accessory mode to OFF after
10 minutes to prevent battery
rundown. ON/RUN/START (Green
Indicator Light) :
This mode is
for driving and starting. With
the ignition off and the brake
pedal applied, pressing
ENGINE START/STOP once
will place the ignition system in
ON/RUN/START. Once engine
cranking begins, release the
button. Engine cranking will
continue until the engine
starts. The ignition will then
remain on. See Starting the
Engine 0254.
Service Mode
This mode is available to verify
the proper operation of the
malfunction indicator lamp as
may be required for emissions
inspection purposes and for
service and diagnostics. See
Automatic Transmission 0261.
With the vehicle off, and the
brake pedal not applied,
pressing and holding ENGINE
START/STOP for more than
five seconds will place the
vehicle in Service Mode. The
instruments and audio

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.

Auto Stop Disable Switch
The automatic engine Stop/
Start feature can be disabled
and enabled by touching the
hsymbol on the center stack.
Auto Stop is enabled each
time you start the vehicle. When the light next to the
h
is illuminated, the system is
enabled.
Engine Heater
The engine heater can provide
easier starting and better fuel
economy during engine
warm-up in cold weather
conditions at or below
−18 °C (0 °F). Vehicles with an
engine heater should be
plugged in at least four hours
before starting. An internal
thermostat in the plug-end of
the cord may exist, which will
prevent engine heater
operation at temperatures
above
−18 °C (0 °F).
{Warning
Do not plug in the engine
block heater while the
vehicle is parked in a garage
or under a carport. Property
damage or personal injury
may result. Always park the

Warning (Continued)
vehicle in a clear open area
away from buildings or
structures.

immediately.
Never park the vehicle with
the engine running in an
enclosed area such as a
garage or a building that has
no fresh air ventilation.
Running the Vehicle
While Parked
It is better not to park with the
engine running.
If the vehicle is left with the
engine running, follow the
proper steps to be sure the
vehicle will not move. See
Shifting Into Park 0258 and
Engine Exhaust 0260.
If parking on a hill and pulling a
trailer, see Driving
Characteristics and Towing
Tips 0322.
Automatic
Transmission
The shift pattern is displayed
in the top of the shift lever.
The selected gear position will
illuminate red on the shift
lever, while all others will be
displayed in white. If the shift
is not immediate, as in very
cold conditions, the indicator
on the shift lever may flash
until it is fully engaged. The shift lever always starts
from a center position,
represented by an up/down
arrow on the shift pattern.
After releasing the shift lever,
it will return to the center
position.
The transmission does not
operate when the vehicle
is off.
If the vehicle is in accessory
mode, the transmission can be
shifted into P (Park).
If the vehicle is turned off
while at a relatively high
vehicle speed, the
transmission will automatically
shift to N (Neutral). Once the
vehicle is stopped, P (Park) is
automatically selected.

P :This position locks the
drive wheels. Use P (Park)
when starting the vehicle to
prevent the vehicle from
moving easily.
{Warning

the vehicle if the
transmission is not in
P (Park) with the parking
brake set. The vehicle
can roll.
(Continued)
Warning (Continued)

running, the vehicle can
move suddenly. You or
others could be injured. To
be sure the vehicle will not
move, even when on fairly
level ground, always set the
parking brake and place the
transmission into P (Park).
See Shifting Into Park 0258
and Electric Parking Brake
0 269.
This vehicle is equipped with
an electronically controlled
transmission. The shift lock
release button is designed to
prevent inadvertent shifting
out of P (Park) unless the
vehicle is on, the brake pedal is
applied, and the shift lock
release button is pressed.
When the vehicle is stopped,
press ENGINE START/STOP
to turn off the vehicle. The
transmission will shift to
P (Park) automatically unless
the vehicle is in N (Neutral),
See “Car Wash Mode” later in
this section.
