Avoid spinning the driven wheels for an
extended period with ESP ®
deactivated.
You could otherwise damage the drivetrain.
X To deactivate:(Y page 348).
The å ESP®
OFF warning lamp in the
instrument cluster lights up.
CL 63 AMG: deactivate ESP ®
when driving
on designated roads when the vehicle's
own oversteering and understeering
characteristics are desired. Driving without
ESP ®
requires an extremely qualified and
experienced driver who is able to cope with
these critical driving conditions.
X To activate:(Y page 348).
The å ESP®
OFF warning lamp in the
instrument cluster goes out.
ESP ®
is activated automaticallyw hen the
engine is started.
If ESP ®
is deactivated and one or more wheels
start to spin, the ÷ESP®
warning lamp in
the instrument cluster flashes. In such
situations, ESP ®
will not stabilize the vehicle.
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
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
R the engine's torque is no longer limited, and
the drive wheels can spin. The spinning of
the wheels results in a cutting action, which
provides better grip.
Vehicles with ECO start/stop function: the
ECO start/stop function switches the engine
off automatically when the vehicle comes to
a stop. 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. EBD (electronic brake force
distribution)
i Observe the "Important safety notes"
section (Y page 64). G
WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This
increases the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified
specialist workshop.
Observe information regarding indicator and
warning lamps (Y page 391) as well as
display messages (Y page 357).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking. ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In
addition to the braking function, ADAPTIVE
BRAKE also has the HOLD function
(Y page 308) and hill start assist
(Y page 275). PRE-SAFE
®
Brake
i Observe the "Important safety notes"
section (Y page 64).
PRE-SAFE ®
Brake is only available in vehicles
with DISTRONIC PLUS.
PRE-SAFE ®
Brake can help you to minimize
the risk of a collision with a vehicle ahead or
reduce the effects of such a collision. If PRE-
SAFE ®
Brake has detected a risk of collision, 68
Driving safety systemsSafety

In particular, the detection of obstacles can
be impaired if:
R
dirt on the sensors or anything else
covering the sensors
R snow or heavy rain
R interference by other radars ources
R there are strong radar reflections, for
example in parking garages
R a narrow vehicle traveling in front, e.g. a
motorbike
R a vehicle traveling in front on a different line
relative to the center of your vehicle G
WARNING
PRE-SAFE ®
Brake does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, PRE-SAFE ®
Brake may neither
give warnings nor intervene in all critical
situations. There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
In order to maintain an appropriate distance
from the vehicle in front and thus prevent a
collision, you must apply the brakes yourself.
X To activate/deactivate: activate or
deactivate PRE-SAFE ®
Brake in the on-
board computer (Y page 348).
After activation, the Äsymbol is
displayed on the left in the instrument
cluster.
For BAS PLUS to assist you, the radar sensor
system must be operational.
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensors checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle. Theft deterrent locking system

Important safety notes
Xenon bulbs G
DANGER
Xenon bulbs carry a high voltage. You could
get an electric shock and be seriously or even
fatally injured if you touch the electric contacts on Xenon bulbs. Therefore, never
remove the cover from Xenon bulbs.
Do not change the Xenon bulbs yourself, but
have them replaced at a qualified workshop.
If your vehicle is equipped with Xenon bulbs,
you can recognize this by the following: the
cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before starting the engine.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.
Other bulbs There are bulbs other than the Xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Y
page 257). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
If you require assistance changing bulbs,
consult a qualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the service life of the bulbs. Always use a lint-
free cloth or only touch the base of the bulb
when installing.
Only use bulbs of the correct type.
If the new bulb still does not light up, consult
a qualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly. G
WARNING
Bulbs and lamps can become very hot. For
this reason, allow them to cool down before
