Trailer Stabilisation - Mercedes-Benz Sprinter Operating Instructions Manual

EBD (Electronic Brake Force Distribu-
tion)
G
WARNING
If EBD is malfunctioning, the rear wheels can
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 spe-
cialist workshop.
EBD monitors and controls the brake pressure
to the rear wheels. This enables EBD to improve
handling during braking.
Observe the information on warning and indica-
Y
tor lamps ( page 218).

ESP (Electronic Stability Program)
Important safety notes
G
WARNING
®
If ESP is malfunctioning it will not provide
any vehicle stabilisation. There is an
increased risk of skidding or of an accident.
Exercise caution when continuing to drive.
®
Have ESP checked at a qualified specialist
workshop.
! Do not operate the vehicle on a roller dyna-
mometer (e.g. for performance testing). If you
have to operate the vehicle on a roller dyna-
mometer, please consult a specialist work-
shop beforehand. You could otherwise dam-
age the drivetrain or the brake system.
If you activate or deactivate the all-wheel drive
in a vehicle with this option, ESP
tivated for the duration of the activation/deac-
tivation process.
®
If ESP is malfunctioning or deactivated, the
Y
h indicator lamp (
while the engine is running and the engine
power may be reduced.
i Use only wheels with the recommended tyre
sizes. Only then will ESP

will be deac-

function properly.
Driving safety systems
4ETS (Electronic Traction System)
! A function or performance test should only
be carried out on a twin-axle dynamometer.
Before you operate the vehicle on such a
dynamometer, please consult a qualified
workshop. You could otherwise damage the
drive train or the brake system.
4ETS is only active when all-wheel drive is acti-
Y
vated ( page 168).
4ETS ensures permanent drive for all four
wheels, and together with ESP
vehicle's traction.
If a driven wheel spins due to lack of traction:
When pulling away, make use of the traction
R
control integrated in ESP
accelerator pedal as far as necessary.
While driving, slowly take your foot off the
R
accelerator pedal
Use winter tyres (M+S tyres), with snow chains
Y
( page 274) if necessary, when the road con-
ditions are wintry. This is the only way to get the
full benefit from the all-wheel drive system.

Trailer stabilisation

G
WARNING
If road and weather conditions are poor,
trailer stabilisation 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
a risk of an accident.
Always adapt your driving style to the prevail-
ing road and weather conditions.
®
ESP trailer stabilisation counteracts critical
driving situations in good time and thereby pro-
vides considerable assistance when driving with
a trailer. Trailer stabilisation is part of ESP
If the sensor system and evaluation logic detect
trailer swinging movements, ESP
lisation firstly brakes individual vehicle wheels in
a targeted manner. It thus counteracts swinging
movements. If the swinging movements do not
stop, the vehicle is braked until the vehicle/
trailer combination is stabilised. If necessary,
the vehicle's engine output is limited.
If your vehicle with trailer (vehicle/trailer com-
bination) starts to swerve, you will be able to
stabilise the vehicle/trailer combination only by
