0 to 1 if you move the
steering wheel slightly to help disengage the
detent.
Individual electrical equipment and accessories

Ignition switched on
All systems are operational.
Starting the engine
Engine idle speed is controlled by the engine
computer system. Increased speeds at start-up
are normal and should decrease as the engine
warms up. If engine speed does not decrease,
service is required.
To prevent the battery from discharging, always
deactivate electrical devices that are not in use.
Switch the ignition off when the vehicle is not
being driven.
Do not leave the engine running in
enclosed spaces. Otherwise, inhalation of
the hazardous exhaust gases could lead to
unconsciousness and death. The exhaust
gases contain carbon monoxide, an odorless
and colorless, but highly toxic gas. Do not leave
the vehicle unattended with the engine running.
An unattended vehicle with a running engine
poses a safety hazard.
Before leaving the car with the engine running,
place the transmission in idle or move the
selector lever to position P and apply the park-
ing brake to prevent the car from moving.
<
When starting the engine, do not press the
accelerator pedal.
Do not end the starting procedure too early, but
do not continue it for more than 20 seconds.
Release the key immediately when the engine
starts.
Do not let the engine warm up in idling position.
Instead, begin to drive at moderate engine
speeds.
Vehicles with manual transmission:
Step on the clutch when starting the vehi-
cle. A lockout prevents the engine from starting
if the clutch is not depressed.
