trailer stabilisation G
WARNING
If road and weather conditions are poor,
traile rstabilisation will not be able to prevent
the vehicle/trailer combination from swerv-
ing .Trailers with a high centre of gravity can
tip over before ESP ®
can detect this. There is
a risk of an accident.
Always adapt yourd riving style to the prevail-
ing road and weather conditions.
If yourv ehicle/trailer combination begins to
lurch, you can only stabilise the vehicle/ Driving safet

trailer combination by depressing the brake
firmly.
In this situation, ESP
®
assists you and can
detect if the vehicle/traile rcombination
begins to lurch. ESP ®
slows the vehicle down
by braking and limiting the engine output until
the vehicle/trailer combination has stabi-
lised.
Trailer stabilisation is active above speeds of
about 65 km/h.
Trailer stabilisation does not work if ESP ®
is
deactivated or disabled because of a mal-
function. EBD (electronic brake force distribu-
tion)
i Observe the "Important safety notes" sec-
tion (Y page 70). G
WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This increa-
ses 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 spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (Y page 301) as well as dis-
play messages (Y page 271).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi-
tion to the braking function, ADAPTIVE BRAKE
also has the HOLD function (Y page 205) and
hill start assist (Y page 164). PRE-SAFE
®
Brake
i Observe the "Important safety notes" sec-
tion (Y page 70).
PRE-SAFE ®
Brake is only available in vehicles
with DISTRONIC PLUS.
PRE-SAFE ®
Brake can help you to minimise
the risk of a collision with a vehicle ahead or
reduce the effects of such a collision. If PRE-
SAFE ®
Brake detects a risk of collision, you
will be warned visually and acoustically as
well as by automatic braking. PRE-SAFE ®
Brake cannot prevent a collision without your
intervention.
This function will issue a warning if:
R at speeds of around 30 km/ho rmore, over
several seconds, the distance maintained
to the vehicle travelling in front is insuffi-
cient.
The · distance warning lamp then lights
up in the instrument cluster.
R at a speed of approximately 7km/h or
higher, you very quickly approach a vehicle
in front.
An intermittent warning tone will then
sound and the ·distance warning lamp
will light up in the instrument cluster.
X Brake immediately in order to increase the
distance from the vehicle in front.
or
X Take evasive action provided it is safe to do
so.
From a speed of approximately 7km/h, if the
driver and passengers have fastened their
seat belts, PRE-SAFE ®
Brake can brake the
vehicle automatically at speeds up to approx-
imatel y200 km/h.
Due to the nature of the system, particularly
complicated driving conditions may cause
unnecessary warnings or the unnecessary
intervention of PRE-SAFE ®
Brake. 76

the vehicle, particularly children, elderly peo-
ple or people requiring special assistance. As
a result, they may not be able to free them-
selves in the event of an emergency. They
could be seriously or even fatally injured by
prolonged exposure to extremely high or low
temperatures, for example. In this case, res- cuing people from outside the vehicle is diffi-
cult.
