i
Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ESP ®
trailer stabilisation If your trailer begins to lurch, you can only
stabilise the vehicle/trailer combination by
depressing the brake firmly.
In this situation, ESP
®
assists you and detects
if the trailer begins to lurch. ESP ®
slows the
vehicle down by braking and limiting the
engine output until the vehicle/trailer com-
bination has stabilised.
Trailer stabilisation is active above speeds of
about 65 km/h. G
Risk of accident
If road and weather conditions are bad, trailer
stabilisation will not be able to prevent the
trailer from swerving and thereby reduce the
risk of accident. Trailers 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.
ETS (Electronic Traction Support) Traction control is part of ESP
®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example, if the road surface is slippery on one
side.
Traction control remains active when you
deactivate ESP ®
. G
Risk of accident
Traction control cannot reduce the risk of an
accident if you drive too fast. Traction control
cannot override the laws of physics.
i If heavy demands are made on the brakes,
traction control switches off automatically
for a brief period so that the brakes do not heat up even further. If traction control
does not intervene for this reason, the
d
warning lamp in the instrument clus-
ter lights up. In addition the multi-function
display shows one of the following mes-
sages: ESP inoperative (vehicles with 4-
button multi-function steering wheel) or
ESP currently unavail. See Owner's
Manual (vehicles with 12-button luxury
multi-function steering wheel)*.
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. Driving safety systems

X
To deactivate: press button:.
The d warning lamp in the instrument
cluster light 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 ®
*(Vehicles with off-road
engineering package*) An ESP
®
system specifically suited to off-road
terrain is activated automatically once the off-
road drive program (Y page 107)is activated.
It intervenes with a delay if there is oversteer-
ing 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 during braking. 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. Anti-theft systems
Immobiliser
The immobiliser prevents your vehicle from
being started without the correct key.
X To activate: remove the key from the igni-
tion lock.
X To deactivate: turn the key to position 2
in the ignition lock. ATA* (anti-theft alarm system)
A visual and audible alarm is triggered when
the alarm system is primed and you open:
R a door
R a door using the emergency key element
R the tailgate
R the bonnet
The alarm is not switched off even if you close
a door again. 54 Anti-theft systemsSafety

Overview of off-road driving systems
The systems which are relevant for off-road
driving are explained on the following pages:
R 4MATIC (permanent four-wheel drive), for
optimum traction
R DSR (Downhill Speed Regulation)* (vehi-
cles with Off-Road Pro engineering pack-
age*), which assists you when driving
downhill
R Off-road driving program* (vehicles with
Off-road Pro engineering package*), which
assists you when driving off-road
You will find further information about driving
off-road in the "Operation" section
(Y page 158). 4MATIC* (permanent four-wheel
drive)
4MATIC ensures that all four wheels are per-
manently driven. Together with ESP ®
and
ETS, it improves the traction of your vehicle
whenever a drive wheel spins due to insuffi-
cient grip. G
Risk of accident
4MATIC cannot reduce the risk of an accident
if you drive too fast.
If a drive wheel spins due to insufficient grip:
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 road and
traffic conditions.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tyres (M+S tyres), with snow
chains if necessary.
! When testing the parking brake, operate
the vehicle only briefly (for a maximum of
ten seconds) on a brake test dynamometer.
When doing this, turn the key to position
0 or 1in the ignition. Failure to do this can
cause damage to 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. DSR (Downhill Speed Regulation)*
(vehicles with the off-road engineer-
ing package*)
You will find information about driving off-
road in the "Operation" section
(Y page 158).
DSR is an aid to assist you when driving down-
hill. It keeps the speed of travel at the speed
selected on the on-board computer. The
steeper the downhill gradient, the greater the
DSR braking effect on the vehicle. When driv-
ing on flat stretches of road or on an uphill Off-road driving
