tions. First-time Mercedes-Benz owners

mation given here.

detail” section will provide you with further 
information. The corresponding page refer-
ences are located at the end of each seg-
ment.

32 Getting startedUnlockingUnlocking with KEYLESS-GO*
If your vehicle is equipped with the 
KEYLESS-GO function, your vehicle checks 
whether the SmartKey with KEYLESS-GO is 
valid when you grasp the door handle. If 
your SmartKey with KEYLESS-GO is valid, 
the doors will unlock and you can open 
them.
The function of the SmartKey overrules the 
KEYLESS-GO function.
Grasp the door handle.
The turn signal lamps flash once. The 
locking knobs on the doors move up.
The SBC brake system is activated.
If the SmartKey with KEYLESS-GO is inside 
the vehicle, pressing the KEYLESS-GO 
start/stop button on the gear selector le-
ver corresponds to turning the SmartKey 
to the various starter switch positions.iTo unlock the vehicle, the SmartKey 
with KEYLESS-GO must be outside the 
vehicle, no further than approx. 3 feet 
(1 meter) away from the door. 
Warning!
G
When leaving the vehicle, always remove the 
SmartKey from the starter switch, take the 
SmartKey with KEYLESS-GO* with you and 
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an 
unlocked vehicle. Unsupervised use of vehi-
cle equipment may cause an accident 
and/or serious personal injury.

44 Getting startedDrivingStarting with KEYLESS-GO*
You can start your vehicle without the 
SmartKey in the starter switch using the 
KEYLESS-GO start/stop button on the 
gear selector lever.
1KEYLESS-GO start/stop button
Make sure the gear selector lever is set 
to P. 
Depress the brake pedal during the 
starting procedure. Do not depress ac-
celerator.
The selector lever lock is released.
Press KEYLESS-GO start/stop 
button1 once.
The engine starts automatically if the 
SmartKey with KEYLESS-GO is in the 
vehicle.
For information on turning off the engine 
with KEYLESS-GO, see “Turning off with 
KEYLESS-GO*” (
page 54).
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 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 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 43). Remember that extended 
starting attempts can drain the battery.
Get a jump start (
page 363).
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.

46 Getting startedDrivingOnce the vehicle is in motion, the automat-
ic central locking system engages and the 
locking knobs drop down.
After a cold start, the transmission engag-
es at a higher revolution. This allows the 
catalytic converter to reach its operating 
temperature earlier.

Turn the switch to B.
For more information, see “Exterior lamp 
switch” (
page 117).
!If you hear a warning signal when driv-
ing off, you have forgotten to release 
the parking brake. 
Release the parking brake.!Do not run cold engine at high engine 
speed. Running a cold engine at high 
engine speed may shorten the service 
life of the engine.
!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes 
premature brake and drivetrain wear.iYou can open a locked door from the 
inside. Open door only when conditions 
are safe to do so.
You can deactivate the automatic lock-
ing using the control system 
(page 146).
