To shift out of P (Park), the vehicle
must be on and the brake pedal must
be applied.
Stopping the Engine/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) 0237.
If the vehicle has an automatic
transmission, and is not in P (Park),
the ignition will return to ACC/
ACCESSORY and display a message in
the Driver Information Center (DIC).
When the vehicle is shifted into
P (Park), the ignition system will
turn OFF.
If the vehicle has a manual
transmission and is stationary, the
ignition will turn off, and Retained Accessory Power (RAP) will remain
active. See
Retained Accessory Power
(RAP) 0237.
The vehicle may have an electric
steering column lock. The lock is
activated when the vehicle is switched
to OFF and the driver 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) with an automatic
transmission, or Neutral with a
manual transmission. Turn the
ignition off.
4. Set the parking brake. See Electric
Parking Brake 0254.
{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 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 within five seconds.

Shifting Into Park
(Mechanical Shifter)
1. Hold the brake pedal down and setthe parking brake. See Electric
Parking Brake 0254.
2. Move the shift lever into P (Park) by holding in the button on the
shift lever and pushing the shift
lever all the way toward the front
of the vehicle.
3. Turn the ignition off.
Leaving the Vehicle with the
Engine Running
{Warning
It can be dangerous to leave the
vehicle with the engine running.
It could overheat and catch fire.
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle can
move suddenly. You or others could
be injured. To be sure the vehicle
will not move, even when you are
on fairly level ground, always set
the parking brake and move the
shift lever to P (Park). See Shifting
Into Park (Mechanical Shifter) 0238
or
Shifting Into Park (Electronic Shifter)
0 239. If you are towing a trailer,
see Driving Characteristics and
Towing Tips 0315. If you have to leave the vehicle with
the engine running, be sure the
vehicle is in P (Park) and the parking
brake is set before you leave it. After
you have moved the shift lever into
P (Park), hold the regular brake pedal
down. Then, see if you can move the
shift lever away from P (Park) without
first pressing the button.
If you can, it means that the shift
lever was not fully locked in P (Park).
Torque Lock
Torque lock is when the weight of the
vehicle puts too much force on the
parking pawl in the transmission. This
happens when parking on a hill and
shifting the transmission into P (Park)
is not done properly and then it is
difficult to shift out of P (Park). To
prevent torque lock, set the parking
brake and then shift into P (Park). To
find out how, see
“Shifting Into Park”
listed previously.
If torque lock does occur, your vehicle
may need to be pushed uphill by
another vehicle to relieve the parking
pawl pressure, so you can shift out of
P (Park).

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. (Continued)
Warning (Continued)
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.
.Have the vehicle repaired
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. See Engine Exhaust 0241.
If the vehicle is left with the engine
running, follow the proper steps to be
sure the vehicle will not move. See
