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
(except high beam headlamp indicator lamp and
turn signal indicator lamps if activated) will go

that the respective systems are operational.
iThe SmartKey can only be removed from the
starter switch with the gear selector lever in park

iIf the SmartKey is left in starter switch
position0 for an extended period of time, it can
no longer be turned in the 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 battery may not be
sufficiently charged.

or a completely discharged vehicle battery,
always remove the SmartKey from the starter
switch when the engine is not in operation.

Jump starting terminals are located on the
driver’s side of the engine compartment
(

The battery should always be sufficiently
charged in order to achieve its rated
service life. Refer to Maintenance Booklet

If you use your vehicle mostly for
short-distance trips, you will need to have
the battery charge checked more
frequently.
When replacing the battery, always use
batteries approved by Mercedes-Benz.

for an extended period of time, consult an
authorized Mercedes-Benz Light Truck
Center about steps you need to observe.Batteries contain materials that can harm
the environment if disposed of improperly.
Large 12-volt storage batteries contain
lead. Recycling of batteries is the preferred
method of disposal. Many states require
