188 Driving and Operating
The Remote Keyless Entry (RKE)
transmitter must be in the vehicle for
the system to operate. If the
pushbutton start is not working, the
vehicle may be near a strong radio
antenna signal causing interference
to the Keyless Access system. See
Remote Keyless Entry (RKE)
System Operation027.
To shift out of P (Park), the vehicle
must be in ON/RUN and the brake
pedal must be applied.
Stopping the Engine/LOCK/
OFF (No Indicator Lights) : When
the vehicle is stopped, press
ENGINE START/STOP once to turn
the engine off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory
Power (RAP) 0192.
If the vehicle is not in P (Park), the
ignition will return to ACC/
ACCESSORY and display the
message SHIFT TO PARK in the
Driver Information Center (DIC).
See Transmission Messages 0148. When the vehicle is shifted into
P (Park), the ignition system will
switch to OFF.
The vehicle may have an electric
steering column lock. The lock is
activated when the vehicle is
switched to OFF and either front
door is opened. A sound may be
heard as the lock actuates or
releases. The steering column lock
may not release with the wheels
turned off center. If this happens,
the vehicle may not start. Move the
steering wheel from left to right
while attempting to start the vehicle.
If this does not work, the vehicle
needs service.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
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, shift to P (Park), and turn the
ignition to OFF. On vehicles
with an automatic transmission,
the shift lever must be in
P (Park) to turn the ignition
switch to the OFF position.
4. Set the parking brake. See Electric Parking Brake 0199.
{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.

190 Driving and Operating
The idle speed will go down as
the engine gets warm. Do not
race the engine immediately
after starting it.
Caution
Cranking the engine for long
periods of time, by returning the
ignition to the START position
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 holding it there as
you hold 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
{Warning
Exiting the vehicle without first
shifting into P (Park) may cause
the vehicle to move. You or others
may be injured. Because the
vehicle may have an auto engine
stop/start feature, the vehicle's
engine might seem to be shut off;
however, once the brake pedal is
released, the engine will start up
again.
(Continued)
Warning (Continued)
Shift to P (Park) and turn the
ignition off before exiting the
vehicle.
The vehicle has a fuel saving stop/
start system to shut off the engine to
help conserve fuel.
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
0 117. When the brake pedal is
released or the accelerator pedal is
pushed, the engine will restart.
Auto Stop may be deactivated if:
. A minimum vehicle speed is not
reached.
. The engine or transmission is
not at the required operating
temperature.

.The outside temperature is not
in the required operating range,
typically between −10 °C (14 °F)
and 50 °C (122 °F).
. The shift lever is in any gear
other than D (Drive).
. The battery charge is low.
. The interior comfort level has not
reached the required level for
the climate control system or
defog settings.
. The Auto Stop time is greater
than two minutes.
Engine Heater
The vehicle may have an engine
heater. The engine heater can help
in cold weather conditions at or
below −18 °C (0 °F) for easier
starting and better fuel economy
during engine warm-up. Plug in the
heater at least four hours before
starting the vehicle. An internal
thermostat in the plug end of the
cord will prevent engine heater
operation at temperatures above
−18 °C (0 °F).
To Use The Engine Heater
1. Turn off the engine.
3. Open the hood and unwrap the
electrical cord. The cord is in
the driver side of the engine
compartment, near the battery.
It is shipped from the factory
with a tie holding it in place.
Use care in removing the tie so
that the cord is not damaged.
Check the heater cord for
damage. If it is damaged, do
not use it. See your dealer for
a replacement. Inspect the
cord for damage yearly. 4. Plug it into a normal, grounded
110-volt AC outlet.
{Warning
Improper use of the heater cord
or an extension cord can damage
the cord and may result in
overheating and fire.
. 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.
. Use a weatherproof,
heavy-duty, 15 amp-rated
extension cord if needed.
Failure to use the
recommended extension
cord in good operating
condition, or using a
damaged heater or
extension cord, could make
