35 Getting started
Unlocking
For information on starting the engine
using the SmartKey, see “Starting the en-
gine” (
page 47).SmartKey with KEYLESS-GO*
Pressing the KEYLESS-GO start/stop but-
ton on the gear selector lever corresponds
to turning the SmartKey to the various
starter switch positions.
If you firmly depress the brake pedal dur-
ing pressing the KEYLESS-GO start/stop
button, the engine starts automatically.
iWhen you switch on the ignition, the in-
dicator and warning lamps (expect 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 (expect 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 cannot be turned in the
starter switch, the starter battery may
not be sufficiently charged.
Check the battery and charge it
if necessary (
page 408).
Get a jump start (
page 428).
To prevent accelerated battery dis-
charge or a completely discharged bat-
tery, always remove the SmartKey from
the starter switch when the engine is
not in operation.
iThe function of the SmartKey overrules
the KEYLESS-GO function.
