The SRS performs a self-test at regular
intervals when the ignition is switched
on and while the engine is running. Mal-
functions can therefore be detected in
good time.
The

warning lamp in the instru-
ment cluster (

approximately 4 seconds when you
switch on the ignition.

There is a malfunction if the

® monitors driving stability and de-
tects a tendency of the vehicle to under-
steer or oversteer (skidding) in good
time. ESP
® stabilizes the vehicle by
braking individual wheels, limiting the
engine power output, and greatly assists
y o u w h e n d r i v i n g o n w e t o r s l i p p e r y r o a d
surfaces. ESP
® also stabilizes the vehi-
cle when braking.
When ESP
® intervenes, the

ing lamp in the speedometer flashes.
Warning
G
If BAS malfunctions, the brake system is
still available with the full brake boosting
effect. In an emergency braking situation,
however, the braking force will not be ad-
ditionally boosted automatically and the
stopping distance may increase.

Warning

Proceed as follows if the v warning
lamp in the speedometer flashes:
\4Do not deactivate ASR under any cir-
cumstances.
\4Only depress the accelerator pedal as
far as necessary when pulling away.
\4Adapt your driving style to suit the
prevailing road and weather condi-
tions.
Otherwise, the vehicle could begin to
skid.
ESP
® cannot reduce the risk of an acci-
dent if you drive too fast. ESP
® is unable
to override the laws of physics.

There is a malfunction if the
#
indica-
tor lamp is permanently lit while the en-
gine is running (

page 468).
If ESP
® malfunctions, engine power out-
put may be reduced.ASR improves traction for a sustained
period, i.e. the transfer of power from
the tires to the road surface, and thus
also improves the driving stability of the
vehicle. ASR assists you when pulling
away and accelerating, especially on
smooth and slippery surfaces.
ASR brakes individual drive wheels and
limits the engine torque to prevent the
drive wheels from spinning. When ASR
intervenes, the
v
indicator lamp in
the speedometer flashes.
!
CAUTION
Only operate the vehicle briefly (max-
imum of 10 seconds) on a brake dy-
namometer. The key must be turned
to position
1 in the ignition lock dur-
ing this time. You could damage the
drive train or the brake system.
!
CAUTION
Do not operate the vehicle on a roller
dynamometer (for example for per-
formance testing). If you wish to op-
erate the vehicle on a roller
dynamometer, please consult an au-
thorized Sprinter Dealer beforehand.
You could otherwise damage the
drive train or the brake system.

If the road surface is not capable of pro-
viding sufficient traction, bearing in
mind the tires, load and gradient, it is
not be possible to pull away smoothly
even with ASR.

If ASR malfunctions, engine power out-
put may be reduced.
Activating/deactivating ASRASR is automatically activated as soon
as the engine is switched on.
It may be best to deactivate ASR in the
following situations:\4
if snow chains are being used
\4
in deep snow
\4
on sand or gravelIf you deactivate ASR:
\4
the engine’s torque is then no longer
limited and the drive wheels could
spin; the spinning wheels produce a
cutting effect for better traction
\4
traction control still intervenes by
braking if one drive wheel reaches its
grip limit, for example if the surface
under one side of the vehicle is slip-
pery. The wheel is then braked to in-
crease traction in this situation.

ESP
® still intervenes to stabilize the

If EBV malfunctions, the brake system is
still available with the full brake boosting
effect. However, the rear wheels may
lock, for example if the brakes are applied
with maximum force. You could then lose
control of the vehicle and cause an acci-
dent. Always adapt your driving style to
the change in handling characteristics.
Have the system checked at an autho-
rized Sprinter Dealer as soon as possible.
