Engine (ignition) switch
(diesel engine)
"START"—Starter motor on. The key
will return to the "ON" position when
released.
For starting tips, see page 247 in Section
3.
"ON"—Engine on and all accessories
on. Before starting, glow plugs on and
engine preheated.
This is the normal driving position.
"ACC"—Accessories such as the radio
operate, but the engine is off.
"LOCK"—Engine is off and the steering
wheel is locked. The key can be re-
moved only at this position.
You must push in the key to turn the key
from "ACC" to the "LOCK" position. On
vehicles with an automatic transmission,
the selector lever must be put in the "P"
position before pushing the key.
Once you remove the key, the engine im-
mobilizer system is automatically set. (See
"Engine immobilizer system" on page 14
in Section 1−2.)
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.
It is not a malfunction if the needles on
all meters and gauges move slightly when
the key is turned to the "ACC", "ON" or
"START" position.
CAUTION
For manual transmission:
Never remove the key when the ve-
hicle is moving, as this will lock the
steering wheel and result in loss of
steering control.
NOTICE
Do not leave the key in the "ON"
position if the engine is not running.
The battery will discharge.
