{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

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

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

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.

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

.Plug the cord into a
three-prong electrical
utility receptacle that is
protected by a ground
fault detection function.
An ungrounded outlet
could cause an electric
shock.

with the heater cord
permanently attached to
the vehicle. Possible
heater cord and
thermostat damage could
occur.

see your dealer for service.
Parking over Things
That Burn
{Warning
Things that can burn could
touch hot exhaust parts
under the vehicle and ignite.
Do not park over papers,
leaves, dry grass, or other
things that can burn.
Active Fuel
Management
This vehicle's engine may be
equipped with Active Fuel
Management, which allows the
engine to operate on either all
of its cylinders, or in reduced
cylinder operation mode,
depending on the driving
conditions.
When less power is required,
such as cruising at a constant
vehicle speed, the system will
operate in reduced cylinder
operation mode, allowing the
vehicle to achieve better fuel

260 Driving and Operating
economy. When greater
power demands are required,
such as accelerating from a
stop, passing, or merging onto
a freeway, the system will
maintain full-cylinder
operation.
If the vehicle has an Active
Fuel Management indicator,
see Driver Information Center
(DIC) for more information on
using this display.
Extended Parking
It is best not to park with the
vehicle running. If the vehicle is
left running, be sure it will not
move and there is adequate
ventilation.
See Shifting Into Park0258
and Engine Exhaust 0260.
If the vehicle is left parked and
running with the remote key
outside the vehicle, it will
continue to run for up to
15 minutes. If the vehicle is left parked and
running with the remote key
inside the vehicle, it will
continue to run for up to
30 minutes.
The vehicle could turn off
sooner if it is parked on a hill,
due to lack of available fuel.
The timer will reset if the
vehicle is taken out of P (Park)
while it is running.
Engine Exhaust
{
Warning
Engine exhaust contains
carbon monoxide (CO),
which cannot be seen or
smelled. Exposure to CO can
cause unconsciousness and
even death.
Exhaust may enter the
vehicle if:
.The vehicle idles in areas
with poor ventilation
(parking garages, tunnels, (Continued)

deep snow that may block
underbody airflow or tail
pipes).
.The exhaust smells or
sounds strange or
different.
.The exhaust system leaks
due to corrosion or
damage.
.The vehicle exhaust
system has been modified,
damaged, or improperly
repaired.
.There are holes or
openings in the vehicle
body from damage or
aftermarket modifications
that are not completely
sealed.
If unusual fumes are
detected or if it is suspected
that exhaust is coming into
the vehicle:
.Drive it only with the
windows completely down. (Continued)

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.

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

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.
