44 Getting startedDrivingStarting difficulties
If the engine does not start as described,
carry out the following steps:
If you are starting the engine with the
SmartKey, turn SmartKey in starter
switch to position0 and repeat starting
procedure.

If you are starting the engine with
KEYLESS-GO: Close any doors that
may be open to allow for better detec-
tion of the KEYLESS-GO card.
or:
Start the engine with the SmartKey as
radio signals from another source may
be interfering with the KEYLESS-GO
card.

Repeat the starting procedure
(page 42). Remember that extended
starting attempts can drain the battery.

Get a jump start (
page 347).If the engine does not start after several
starting attempts, there could be a mal-
function in the engine electronics or in the
fuel supply system.

Notify an authorized Mercedes-Benz
Center.

ate the equipment installed on your vehi-
cle. If you are already familiar with the
basic functions of your vehicle, this section
will be of particular interest to you.
To quickly familiarize yourself with the ba-
sic functions of the vehicle, see “Getting
started” (

SmartKeys with remote controls and a re-
movable mechanical key. The locking tabs
for the mechanical key portion of the two
SmartKeys are a different color to help dis-
tinguish each SmartKey unit.
The SmartKey provides an extended oper-
ating range. To prevent theft, however, it is
advisable to only unlock the vehicle when
you are in close proximity to it.
