Key Lock Release
The vehicle is equipped with an
electronic key lock release. The key
lock release is designed to prevent
ignition key removal unless the shift
lever is in P (Park). The key lock release is always
functional except in the case of an
uncharged or low voltage (less than
9-volt) battery. If the vehicle has an
uncharged battery or a battery with
low voltage, try charging or jump
starting the battery. See
Jump
Starting - North America 0290.
If charging or jump starting the
battery does not work, locate the
hole below the ignition lock. Insert a
flat bladed tool or another key from
the key chain into the opening.
When the lever can be felt, actuate
the lever toward the driver, and
remove the key from the ignition.
