Risk of accident
If the v warning lamp in the instrument
cluster flashes, proceed as follows:
R Only depress the accelerator pedal as far
as necessary when pulling away.
R Accelerate less when driving.
R Adapt your driving style to suit prevailing
road and weather conditions.
The vehicle could otherwise go into a skid.
If you drive too fast, 4-ETS cannot reduce
the risk of an accident. 4-ETS cannot over-
ride the laws of physics.
! Only operate the vehicle briefly (for a max-
imum of ten seconds) on a brake dyna-
mometer. Turn the key in the ignition lock
to position 0or 1. You could otherwise
damage the drive train or the brake system.
! A function or performance test should
only be carried out on a twin-axle dyna-
mometer. If you wish to operate the vehicle
on such a dynamometer, please consult a
Mercedes-Benz Service Centre in advance.
You could otherwise damage the drive train
or the brake system. i
If heavy demands are made on the brakes,
4-ETS switches off automatically for a brief
period so that the brakes do not heat up
further. If, for this reason, 4-ETS does not
engage, the vwarning lamp in the
instrument cluster lights up. The message
ABS, ESP unavailable see Owner's
Manual also appears in the multi-function
display.
! The engine may be switched on when the
vehicle is towed with its axle raised or when
the parking brake is checked on the brake
dynamometer. Application of the brakes
via 4-ETS may otherwise destroy the brake
system.
Off-road 4-ETS A 4-ETS system specifically suited to off-road
terrain is activated automatically if the off-
road drive program is activated
(Y page 140) or the LOW RANGE* off-road
gear is selected (Y page 141). Distance warning system (only for
vehicles with Distronic*)
This function will issue a warning at speeds of
around 30 km/h or more if:
R for a period of several seconds, the dis-
tance to the vehicle in front is too short for
the speed at which you are travelling. The
distance warning lamp lin the instru-
ment cluster will then light up.
R you are approaching the vehicle in front too
rapidly. An intermittent warning tone will
then sound and the distance warning lamp
l will light up in the instrument cluster.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a
crash, you must apply the brakes yourself. G
Risk of accident
Pay particular attention to the traffic con-
ditions if the distance warning lamp l
in the instrument cluster lights up or an
intermittent warning tone sounds.
If necessary, brake or swerve to avoid an
obstacle. Safety

The optional equipment supplied with your
vehicle includes two KEYLESS GO keys. You
can start, lock or unlock the vehicle using the
KEYLESS GO key. To do this, you need only
carry the KEYLESS GO key on your person.
When you touch the surface of the sensors on
the vehicle's door handles, KEYLESS GO
establishes a radio connection between the
vehicle and the key. The distance between
the KEYLESS GO key and the vehicle's door
handle from which you wish to lock or unlock
the vehicle, must not be greater than 1 m.
When you pull the door handle, the following
unlock centrally if the factory settings have
not been changed:
R the doors
R the tailgate
R the fuel filler flap
If you pull on the handle of the tailgate, only
the tailgate of your vehicle is unlocked.
When starting the engine and whilst driving,
KEYLESS GO also checks whether a valid
KEYLESS GO key is in the vehicle by periodi-
cally establishing radio contact. G
Risk of accident
If children are left unsupervised in the vehi-
cle, they could open a door from the inside,
even if it has been locked. Or they could
start the vehicle if a valid KEYLESS GO key
is in the vehicle and they press the KEY-
LESS GO button on the ignition lock. They
could endanger themselves and others.
Never leave children unsupervised in the
vehicle. Switch off the engine and take the
KEYLESS GO key with you, even if you are
only leaving the vehicle for a short time. 1

the KEYLESS GO key, the following mes-
sage will appear in the multi-function dis-
play as you pull away: Key not detec-
ted.
R If the KEYLESS GO key is in the vehicle, the
