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

Points to remember
Depending on the vehicle equipment, you can
adjust the steering wheel either manually or
electrically*. G
Risk of accident
Only adjust the steering wheel when the
vehicle is stationary and do not pull away
until the steering wheel adjustment mech-
anism is locked in position. You might oth-
erwise drive without the steering wheel
adjustment mechanism being locked in
position. As a result you could be distracted
from road and traffic conditions by an unex-
pected movement of the steering wheel
and thereby cause an accident.
The steerability of the vehicle is however
not affected.
When you adjust the steering wheel, make
sure that:
R the steering wheel can be reached with
your arms slightly bent
R you can move your legs freely
R you can see all the displays in the instru-
ment cluster clearly Adjusting the steering wheel man-

Light switch
For safety reasons, Mercedes-Benz recom-
mends that you drive with the lights switched
on even during the daytime. In some coun-
tries, daytime operation of headlamps varies
due to legal and voluntary requirements. In
these countries, the dipped-beam headlamps
are automatically switched on when the
engine is started.
i If you drive in countries in which traffic
drives on the opposite side of the road to
the country where the vehicle is registered,
oncoming traffic may be dazzled by the
asymmetrical dipped-beam headlamps.
Have the headlamps changed to symmet-
rical dipped beam when driving in these
countries. You can obtain information
about this from any Mercedes-Benz Service
Centre. Controls
