1Power supply for some electrical con-
sumers, such as seat adjustment
2Ignition (power supply for all electrical
consumers) and driving position
All lamps (except high beam headlamp
indicator 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” (
page 436).
3Starting position
iWhen you switch on the ignition, the indica-
tor and warning lamps (except high beam head-
lamp indicator lamp and turn signal indicator
lamps unless activated) in the instrument cluster
come on. The indicator and warning lamps (ex-
cept high beam headlamp indicator lamp and
turn signal indicator lamps if activated) will go
out when the engine is running. This indicates
that the respective systems are operational.
iIf the SmartKey does not belong to the
vehicle, the SmartKey can be turned in the start-
er switch. However, the ignition does not switch
on and the engine does not start.
iWhen the SmartKey is removed from the
starter switch and the automatic transmission is
in a position other thanP, the automatic trans-
mission automatically shifts toP.
!If the SmartKey cannot be turned in the
starter switch, the battery may not be sufficient-
ly charged.

Check the battery and charge it if necessary
(
page 528).

Get a jump start (page 536).
To prevent accelerated battery discharge or a
completely discharged battery, always remove
the SmartKey from the starter switch when the
engine is not in operation.
