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. The vwarning
lamp in the instrument cluster lights up if
traction control is not engaging for this rea-
son. The message ABS, ESP unavailable
see Owner's Manual also appears in the
multi-function display.
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. 1
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. Safety

X
To activate: press button 1.
The v warning lamp in the instrument
cluster goes out. 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. 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. X
To activate/deactivate: activate or deac-
tivate the distance warning system in the
on-board computer (Y page 136).
After activation, the :symbol is dis-
played in the lower multi-function display.
For more information on the distance warning
system, see the Distronic* section
(Y page 143). Safety

The optional equipment supplied with your
vehicle includes two KEYLESS GO keys. You
can start, lock or unlock the vehicle using the
KEYLESS GO key. To do this, you need only
carry the KEYLESS GO key on your person.
When you touch the surface of the sensors on
the vehicle's door handles, KEYLESS GO
establishes a radio connection between the
vehicle and the key. The distance between
the KEYLESS GO key and the vehicle's door
handle from which you wish to lock or unlock
the vehicle, must not be greater than 1 m.
When you pull the door handle, the following
unlock centrally if the factory settings have
not been changed:
R the doors
R the tailgate
R the fuel filler flap
If you pull on the handle of the tailgate, only
the tailgate of your vehicle is unlocked.
When starting the engine and whilst driving,
KEYLESS GO also checks whether a valid
KEYLESS GO key is in the vehicle by periodi-
cally establishing radio contact. G
Risk of accident
If children are left unsupervised in the vehi-
cle, they could open a door from the inside,
even if it has been locked. Or they could
start the vehicle if a valid KEYLESS GO key
is in the vehicle and they press the KEY-
LESS GO button on the ignition lock. They
could endanger themselves and others.
Never leave children unsupervised in the
vehicle. Switch off the engine and take the
KEYLESS GO key with you, even if you are
only leaving the vehicle for a short time. 1
