Starting 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 position 0 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 SmartKey with
KEYLESS-GO.
Or:
Start the engine with the SmartKey as
radio signals from another source may
be interfering with the SmartKey with
KEYLESS-GO*.
Repeat the starting procedure
( page 49). Remember that extended
starting attempts can drain the battery.
Get a jump start ( page 419).
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.
