Signals from electronic equipment can cause
interference in the automatic child seat rec-
ognition sensor system. This could lead to a
system malfunction. This may cause the
4 PASSENGER AIRBAG OFF warning lamp
to light up without there being a child seat
with automatic child seat recognition fitted. This means that the front-passenger front air-
bag will not deploy during an accident. It is
also possible that the 6SRS warning lamp
lights up and/or the 4PASSENGER AIR-
BAG OFF warning lamp does not light up
briefly when you turn the key in the ignition
lock to position 2.

the trailer from swerving and will thus be
unable to reduce the risk of an accident. Trail-
ers with a high centre of gravity can tip over
before ESP ®
can detect this.
Trailer stabilisation does not work if ESP ®
is
deactivated or disabled because of a mal-
function.
Activating/deactivating ESP ®ESP
®
is activated automatically when the
engine is running.
It may be best to deactivate ESP ®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel G
Risk of accident
Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilise the vehicle
if the vehicle starts to skid or a wheel starts
to spin.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R the engine's torque is no longer limited and
the drive wheels can spin. Spinning of the
wheels results in a cutting action, which
provides better grip.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
i If ESP ®
is deactivated and one or more
wheels start to spin, the dwarning lamp
in the instrument cluster flashes. In such
situations, ESP ®
will not stabilise the vehi-
cle. X
To deactivate: press button:.
The d warning lamp in the instrument
cluster lights up. G
Risk of accident
If the d warning lamp in the instrument
cluster is continuously lit when the engine is
running, ESP ®
is deactivated or not available
due to a malfunction. There is an increased
risk of your vehicle skidding in certain situa-
tions.
You should always adapt your driving style to
suit prevailing road and weather conditions.
X To activate: press button :.
The d warning lamp in the instrument
cluster goes out.
Off-road ESP ® An ESP
®
system specifically suited to off-road
terrain is activated automatically if the LOW
RANGE off-road gear (Y page 114) is selec-
ted. It intervenes with a delay if there is over-
steering or understeering, thus improving
traction. EBV (electronic brake force distribu-
tion)
EBV monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability when braking. 52

G
Risk of accident
If EBV is malfunctioning, the brake system is
still available with full brake boosting effect.
However, the rear wheels can still lock, e.g.
under full braking. This could cause you to
lose control of your vehicle and cause an acci-
dent. You should therefore adapt your driving
style to the different handling characteristics. 4ETS (Electronic Traction System)
4ETS makes it possible to pull away or accel-
erate on a slippery surface. It brakes the
wheels individually if they start to spin.
The d warning lamp in the instrument
cluster lights up briefly when the engine is
started. This indicates that the warning lamp
is operational.
X Activate the LOW RANGE off-road gear
(Y page 114) if appropriate to driving con-
ditions.
The d warning lamp in the instrument
cluster flashes at any speed if at least one tyre
has exceeded its tyre grip limit. G
Risk of accident
If the d 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 the prevail-
ing road and weather conditions.
Otherwise, the vehicle could skid.
If you drive too fast, 4ETS cannot reduce the
risk of an accident. 4ETS cannot override 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 the brakes are subjected to heavy loads,
4ETS switches off automatically for a brief
period so that the brakes do not heat up
further. If, for this reason, 4ETS does not
engage, the dwarning 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 must be off when the parking
brake is being checked on the brake dyna-
mometer. Application of the brakes via
4ETS may otherwise destroy the braking
system.
Off-road terrain-4ETS (Electronic Trac-
tion System) A 4ETS system specifically suited to off-road
terrain is activated automatically if the LOW
RANGE* off-road gear is selected
(Y page 114). Distance warning function* (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 in the instru-
ment cluster will light up.
R you are approaching the vehicle in front too
rapidly. An intermittent warning tone will
then sound and the ·distance warning
lamp will light up in the instrument cluster. Driving safety systems

tries, daytime operation of headlamps varies
due to legal and voluntary requirements. In
these countries, daytime driving lights are
automatically switched on when the engine is
started.
The exterior lighting (except the side lamp/
parking lamp) switches off automatically if
you:
R remove the key from the ignition lock
R open the driver's door when the ignition is
switched off (key in position 0in the igni-
tion lock)
! Switch off the side lamps and parking
lamp when you leave the vehicle. This pre-
vents the battery from discharging.
Notes on driving abroad Converting to symmetrical dipped beam
when driving abroad:
switch the headlamps
to symmetrical dipped beam in countries in which traffic drives on the opposite side of the
road to the country where the vehicle is reg-
istered. This prevents oncoming traffic from
being dazzled
Have the headlamps converted at a qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre, as close to the border as pos-
sible before driving in these countries. Sym-
metrical lights do not illuminate as large an
area of the edge of the carriageway.
Converting to asymmetrical dipped beam
after returning: have the headlamps conver-
ted back to asymmetrical dipped beam at a
qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre, as soon as
possible after crossing the border and return-
ing to the original country.
Vehicles with Intelligent Light System*: if
the headlamps are converted to symmetrical
dipped beam, not all light functions are avail-
able. "Motorway mode" and the "extended
range foglamps" are deactivated. Function
