ment cluster fails to come on when the

When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Unsuper-
vised use of vehicle equipment may cause
an accident and/or serious personal injury.
iWhen you switch on the ignition, the
indicator and warning lamps (except
high beam headlamp indicator lamp
and turn signal indicator lamps if acti-
vated) in the instrument cluster come
on. This indicates that the respective
systems are operational. They should
go out when the engine is running.
!If the SmartKey is left in the starter
switch position0 for an extended peri-
od of time, it can no longer be turned in
the starter switch.
Remove the SmartKey from the
starter switch and reinsert.
If the SmartKey can still not be turned
in the starter switch, the starter battery
may not be sufficiently charged.
Have the starter battery checked
and charged if necessary
(page 355). Contact an autho-
rized Mercedes-Benz Center.
To prevent accelerated battery
discharge and a possible dead battery,
always remove the SmartKey from the
starter switch when the engine is not in
operation.

iYou should not disconnect the consum-
er battery if you do not intend to use
your SLR for a longer period. Instead,
maintain the condition of the battery by
using the battery charger approved by
Mercedes-Benz for use on the SLR and
supplied with the car (
page 356).
This charger automatically controls the
charge rate, and can be left connected
to the car for long periods without dam-
age to the battery.
If the battery supplying the vehicle’s
electrical consumers is disconnected,
the days of disconnection will not be in-
cluded in the count shown by the ser-
vice indicator. To arrive at the true
service deadline, you will need to sub-
tract these days from the days shown
in the service indicator.
Do not confuse the maintenance
service indicator with the engine oil
level indicator:.
