There is a malfunction if the # indicator
lamp is permanently lit while the engine is
running ( page 272).
If ESP
®
malfunctions, engine power output
may be reduced.
ASR improves traction for a sustained peri-
od, i.e. the transfer of power from the tires
to the road surface, and thus also improves
the driving stability of the vehicle. ASR as-
sists you when pulling away and accelerat-
ing, 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 in-
tervenes, the v indicator lamp in the
speedometer flashes.
If the road surface is not capable of provid-
ing sufficient traction, bearing in mind the
tires, load and gradient, it is not be possi-
ble to pull away smoothly even with ASR.
Vehicles without steering wheel buttons:
There is a malfunction if the k indicator
lamp is permanently lit while the engine is
running ( page 270).
If ASR malfunctions, engine power output
may be reduced.
Warning G
Proceed as follows if the v warning lamp
in the speedometer flashes:
Do not deactivate ASR under any cir-
cumstances.
Only depress the accelerator pedal as
far as necessary when pulling away.
Adapt your driving style to suit the pre-
vailing road and weather conditions.
Otherwise, the vehicle could begin to skid.
ESP
®
cannot reduce the risk of an accident
if you drive too fast. ESP
®
is unable to over-
ride the laws of physics.
!CAUTION
Only operate the vehicle briefly (maxi-
mum of 10 seconds) on a brake dyna-
mometer. The key must be turned to
position 1 in the ignition lock during
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 perfor-
mance testing). If you wish to operate
the vehicle on a roller dynamometer,
please consult an authorized Sprinter
Dealer beforehand. You could other-
wise damage the drive train or the
brake system.
