38 Getting started
Unlocking
For information on starting the engine, see 
(
page 51).
iWhen you switch on ignition, the indicator 
and warning lamps (except high beam headlamp 
indicator lamp and turn signal indicator lamps 
unless activated) in the instrument cluster come 
on. The indicator and warning lamps (except high 
beam headlamp indicator lamp and turn signal 
indicator lamps if activated) will go out when the 
engine is running. This indicates that the respec-
tive systems are operational.
iVehicles with automatic transmission*: The 
SmartKey can only be removed from the starter 
switch with the gear selector lever in positionP.
iIf the SmartKey is left in starter switch 
position 0 for an extended period of time, it can 
no longer be turned in the starter switch. In this 
case the steering is locked. To unlock, remove 
SmartKey from the starter switch and reinsert.
!If the SmartKey cannot be turned in the 
starter switch, the vehicle battery may not be 
sufficiently charged.
Check the vehicle battery and charge it if 
necessary (
page 422).
Get a jump start (page 426).
To prevent accelerated vehicle battery discharge 
or a completely discharged vehicle battery, 
always remove the SmartKey from the starter 
switch when the engine is not in operation.
