8-16 Driving and Operating
D (START): This position starts the
engine. When the engine starts,
release the key. The ignition switch
will return to ON/RUN for normal
driving.
A warning tone sounds when the
driver door is opened when the
ignition is still in ACC/ACCESSORY
and the key is in the ignition.
Key Lock Release
Vehicles with an automatic
transmission are equipped with an
electronic key lock release system.
This system is to prevent ignition
key removal unless the gear lever is
in P (Park).
The key lock release will not work
if the battery is charged less than
9-volts, or uncharged. Try charging
or jump starting the battery. See
Jump Starting on page 9‑64
If charging or jump starting the
battery does not work, there is a
manual key lock release. Locate the
hole below the ignition lock. Insert a
tool or key into the opening. Locate
the lever, and press it toward the
driver while removing the key from
the ignition.
Ignition Positions
(Keyless Access)
The vehicle has an electronic
keyless ignition with pushbutton
start.
Pressing the button cycles it through
three modes, ACC/ACCESSORY,
ON/RUN/START, and Stopping the
Engine/OFF.
