snow chains. Only in this way will the
driving safety systems described in this
section work as effectively as possible. ABS (Anti-lock Braking System)
General information ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.
The 0025 ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
Important safety notes i
Observe the "Important safety notes"
section (Y page 70). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are deactivated. There is an increased danger
of skidding and accidents.
Drive on carefully. Have ABS checked
immediately at a qualified specialist
workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 304) and
display messages which may be shown in the
instrument cluster (Y page 266).
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface
conditions. ABS works on slippery surfaces,
even when you only brake gently. Braking X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking
situation is over.
X To make a full brake application:
depress the brake pedal with full force.
If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.
The pulsating brake pedal can be an
indication of hazardous road conditions, and
functions as a reminder to take extra care
while driving. BAS (Brake Assist System)
General information BAS operates in emergency braking
situations. If you depress the brake pedal
quickly, BAS automatically boosts the braking
force, thus shortening the stopping distance.
Important safety notes
i
Observe the "Important safety notes"
section (Y page 70). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking X
Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. Driving safety systems

already been recognized as such at least once
over the period of observation. Adaptive
Brake Assist does not react to stationary
obstacles. ESP
®
(Electronic Stability Program)
General notes i
Observe the "Important safety notes"
section (Y page 70).
ESP ®
monitors driving stability and traction,
i.e. power transmission between the tires and
the road surface.
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. The engine output is also modified to
keep the vehicle on the desired course within
physical limits. ESP ®
assists the driver when
pulling away on wet or slippery roads. ESP ®
can also stabilize the vehicle during braking.
ETS/4ETS (Electronic Traction System) i
Observe the "Important safety notes"
section (Y page 70).
ETS/4ETS traction control is part of ESP ®
.
Traction control brakes the drive wheels
individually 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. In addition, more drive torque is
transferred to the wheel or wheels with
traction.
Traction control remains active, even if you
deactivate ESP ®
.
Important safety notes G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilize the vehicle. Additionally, further
driving safety systems are deactivated. This
increases the risk of skidding and an accident. Drive on carefully. Have ESP
®
checked at a
qualified specialist workshop.
! Vehicles with 4MATIC: switch off the
ignition when the electric parking brake is
being tested on a brake dynamometer.
Application of the brakes by ESP ®
may
otherwise destroy the brake system.
Vehicles without 4MATIC: observe the notes
on ESP ®
(Y page 377) when towing the
vehicle with a raised rear axle.
ESP ®
is deactivated if the 00BBwarning lamp
in the instrument cluster lights up
continuously when the engine is running.
If the 00E5 warning lamp lights up
continuously, ESP ®
is not available due to a
malfunction.
Observe the information on warning lamps
(Y page 305) and display messages which
may be shown in the instrument cluster
(Y page 266).
i Only use wheels with the recommended
tire sizes. Only then will ESP ®
function
properly.
Characteristics of ESP ® General information
If the
00E5 ESP warning lamp goes out before
beginning the journey, ESP ®
is automatically
active.
If ESP ®
intervenes, the 00E5ESP®
warning
lamp flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any
circumstances.
X Only depress the accelerator pedal as far
as necessary when pulling away.
X Adapt your driving style to suit the
prevailing road and weather conditions. 76
Driving safety systemsSafety

ECO start/stop function
The ECO start/stop function switches the
engine off automatically when the vehicle
stops moving. The engine starts
automatically when the driver wants to pull
away again. ESP ®
remains in its previously
selected status. Example:if ESP®
was
deactivated before the engine was switched
off, ESP ®
remains deactivated when the
engine is switched on again.
Deactivating/activating ESP ®Important safety notes
i
Observe the "Important safety notes"
section (Y page 70).
You can select between the following states
of ESP ®
:
R ESP ®
is activated.
R ESP ®
is deactivated. G
WARNING
If you deactivate ESP ®
, ESP ®
no longer
stabilizes the vehicle. There is an increased
risk of skidding and an accident.
Only deactivate ESP ®
in the situations
described in the following.
It may be best to deactivate ESP ®
in the
following situations:
R when using snow chains
R in deep snow
R on sand or gravel
i Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilize the
vehicle if the vehicle starts to skid or a
wheel starts to spin.
! Avoid spinning the driven wheels for an
extended period with ESP ®
deactivated.
You could otherwise damage the drivetrain. Deactivating/activating ESP
®
You can deactivate or activate ESP ®
via the
on-board computer.
X To deactivate:(Y page 77).
The 00BB ESP®
OFF warning lamp in the
instrument cluster lights up.
X To activate: (Ypage 77).
The 00BB ESP®
OFF warning lamp in the
instrument cluster goes out.
Characteristics when ESP ®
is deactivated
If ESP ®
is deactivated and one or more wheels
start to spin, the 00E5ESP®
warning lamp in
the instrument cluster flashes. In such
situations, ESP ®
will not stabilize the vehicle.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R engine torque is no longer limited and the
drive wheels are able to spin.
The spinning of the wheels results in a
cutting action for better traction on loose
surfaces.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
Crosswind driving assistance General information
Vehicles with MAGIC BODY CONTROL:
information on stabilizing the vehicle in the
event of crosswind (Y
page 213).
Strong crosswinds can cause your vehicle to
deviate from a straight course. The crosswind
driving assistance function integrated into
ESP ®
significantly reduces these effects.
ESP ®
intervenes automatically according to
the direction and intensity of the crosswinds
affecting your vehicle.
ESP stabilities the vehicle with braking
interventions to assist you in keeping the
vehicle in the lane.
Crosswind driving assistance is active at
vehicle speeds above 50 mph (80 km/h) Driving safety systems

WARNING
If head restraints are not installed and
adjusted correctly, they cannot provide
protection as intended. There is an increased
risk of injury in the head and neck area, e.g.
in the event of an accident or when braking.
Always drive with the head restraints
installed. Before driving off, make sure for
every vehicle occupant that the center of the
head restraint supports the back of the head
at about eye level. G
WARNING
If the front-passenger seat is in chauffeur
mode and the front-passenger head restraint
is folded down, the view of the passenger-side
exterior mirror can be impaired. There is a risk
of an accident.
To have a free view of the exterior mirror,
remove the front-passenger head restraint.
