“LOCK” — Engine is off and the steering wheel is locked.
The ignition key can be removed only at this position.
To turn the key from “ACC” to the “LOCK” position, you must
put the transmission selector lever in the “P” position.
Once you remove the key, the engine immobilizer system is
automatically set. See “Engine immobilizer system” on page
12.
When starting the engine, the key may seem stuck at the
“LOCK” position. To free it, first be sure the key is pushed all
the way in, and then rock the steering wheel slightly while
turning the key gently.
Approximately five hours after the engine is turned off, you may
hear sound coming from underneath the luggage compartment
for several minutes. This is normal operation and does not
indicate a malfunction. (See “Leak detection pump” on page
vii.)
If, in an emergency, you must turn the engine off while the
vehicle is moving, turn the key only to “ACC”.
If is not a malfunction if the needles on all meters and gauges
move slightly when the key is turned tp the “ACC”, “ON” or
“START” position.
