Ignition Positions
(Keyless Access)
The vehicle has an electronic
keyless ignition with pushbutton
start.
Pressing the button cycles it through
three positions, ACC/ACCESSORY,
ON/RUN/START and OFF.
The transmitter must be in the
vehicle for the system to operate.
If the push-button 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 Operation (Key
Access)
on page 13
or Remote
Keyless Entry (RKE) System
Operation (Keyless Access)
on
page 15
for more information.
To shift out of P (Park), the vehicle
must be in ACC/ACCESSORY or
ON/RUN and the brake pedal must
be applied.
OFF: When this button is pressed
with the engine running, the engine
will be turned 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)
on page 820
for
more information.
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 Driver Information Center (DIC)
on page 426
for more information.
When the vehicle is shifted into
P (Park), the ignition system will
switch to OFF.
ACC/ACCESSORY: This position
allows you to use some electrical
accessories when the engine is off.
With the ignition off, pressing the
button one time without the brake
pedal applied, will place the ignition
system in ACC/ACCESSORY.
The ignition will switch from
ACC/ACCESSORY to OFF after
five minutes to prevent battery
run down.
