9-18 Driving and Operating
D (START): This position starts the
engine. When the engine starts,
release the key. The ignition switch
returns to ON/RUN for driving.
A warning tone will sound when the
driver door is opened, the ignition is
in ACC/ACCESSORY or LOCK/
OFF, and the key is in the ignition.
Ignition Positions
(Keyless Access)
You can turn the ignition control
knob to four different positions.
To shift out of P (Park), the ignition
must be in ON/RUN or ACC/
ACCESSORY and the regular brake
pedal must be applied.
Using a tool to force the ignition
control knob from its cylinder could
damage it.
Make sure the keyless access
transmitter is inside the vehicle
when trying to turn the ignition
control knob.
A (STOPPING THE ENGINE/
LOCK/OFF): When the vehicle is
stopped, turn the ignition switch to
LOCK/OFF to turn the engine off.
Retained Accessory Power (RAP)
will remain active. See Retained
Accessory Power (RAP) on
page 9 19
The ignition control knob cannot be
removed from the vehicle. The
keyless access transmitter must be
inside the vehicle to start the
engine. This position locks the
ignition and shifter on automatic
transmission vehicles, and the
ignition and steering wheel on
manual transmission vehicles.
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.
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 neutral. This
can be done while the vehicle is
moving. After shifting to neutral,
firmly apply the brakes and steer
the vehicle to a safe location.
