2Ignition (power supply for all electrical
consumers) and driving position.
All lamps (except low beam headlamp
indicator lamp, high beam headlamp in-
dicator lamp, and turn signal indicator
lamps unless activated) in the instru-
ment cluster come on. If a lamp in the
instrument cluster fails to come on
when the ignition is switched on, have
it checked and replaced if necessary. If
a lamp in the instrument cluster re-mains on after starting the engine or
comes on while driving, refer to “Lamps
in instrument cluster” (

3Starting position
For information on starting the engine us-
ing the SmartKey, see “Starting with the
SmartKey” (
page 46).
iWhen you switch on the ignition, the in-
dicator and warning lamps (except low
beam headlamp indicator lamp, high
beam headlamp indicator lamp, and
turn signal indicator lamps unless acti-
vated) in the instrument cluster come
on. This indicates that the respective
systems are operational. The indicator
and warning lamps (except low beam
headlamp indicator lamp, high beam
headlamp indicator lamp, and turn sig-
nal indicator lamps if activated) should
go out when the engine is running.iThe SmartKey can only be removed
from the starter switch with the gear
selector lever in position P.
!If the SmartKey can still not be turned,
the battery may not be sufficiently
charged.

Check the battery and charge it if
necessary (
page 435).

charge or a completely discharged bat-
tery, always remove the SmartKey from
the starter switch when the engine is
not in operation.

starting attempts, there could be a mal-
function in the engine electronics or in the
fuel supply system.
