cannot reduce the risk of an accident
if you drive too fast. ESP ®
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 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 so the vehicle/trailer combi-
nation can stabilise.
Trailer stabilisation is active from about
65 km/h. G
Risk of accident
If road and weather conditions are bad,
trailer stabilisation will not be able to pre-
vent 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 stabilising 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 vehi-
cle 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 vwarning lamp
in the instrument cluster flashes. In such
situations ESP ®
will not stabilise the vehi-
cle. Safety

To deactivate/activate ESP ®
X To deactivate: press button1.
The v warning lamp in the instrument
cluster lights up. G
Risk of accident
If the v warning lamp in the instrument
cluster is continuously lit when the engine
is running, ESP ®
is deactivated or not avail-
able due to a malfunction. There is an
increased risk of your vehicle skidding in
certain situations.
You should always adapt your driving style
to suit prevailing road and weather condi-
tions. X
To activate: press button 1.
The v 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 off-
road drive program is activated
(Y page 140) or if the LOW RANGE* off-road
gear is selected (Y page 141). It intervenes
with a delay if there is oversteering or under-
steering, thus improving traction. EBV (electronic brake-power distribu-
tion)
EBV monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability under 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 accident. You should there- fore adapt your driving style to the different
handling characteristics.
4ETS
4-ETS makes it possible to pull away or accel-
erate on a slippery surface. It brakes the
wheels individually if they start to spin.
The v 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 off-road drive program
(Y page 140) or the LOW RANGE* off-road
gear (Y page 141) if appropriate to driving
conditions.
The v warning lamp in the instrument
cluster flashes at any speed if at least one tyre
has exceeded its tyre grip limit. Safety

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

Risk of accident
Do not keep any objects in the driver's foot-
well. If you use a floormat or carpet in the
driver's footwell, make sure that they are
correctly secured and that there is suffi-
cient clearance for the pedals.
Objects could otherwise get between the
pedals in the event of sudden braking or
acceleration. You may then no longer be
able to brake, change gear or accelerate as
intended. This may result in an accident and
injury. G
Risk of poisoning
Never leave the engine running in enclosed
spaces. The exhaust gases contain carbon
monoxide. Inhaling exhaust fumes consti-
tutes a health hazard and could lead to loss
of consciousness or even death.
! Do not depress the accelerator pedal
when starting the engine. i
If you depress the brake when starting the
engine, pedal travel will be unusually long
and there will be less pedal resistance.
