NOTE: On long and steep downhill slopes, reduce the
load on the brakes by shifting down a gear to utilize the
braking effect of the engine.
To prevent corrosion on the brake pads, after driving
on very wet roads, especially if road salts have been
used, apply brakes before parking the vehicle. The heat
generated will help to dry the brake disks.Brake Pad Wear Indicator
When the key is turned to position 2 in the ignition
lock, the indicator lamp2 in the instrument cluster
lights up for about 2 seconds. It must go out when the
engine is running.
If the 2indicator lamp lights up while the engine is
running, the brake pads are worn almost to their limit.
Have the brake system examined as soon as possible
by an authorized Sprinter Dealer.

as the voltage reaches this level again – the ABS is then
reactivated.
If ABS malfunctions, the other driving safety systems
are deactivated. The handling and braking
characteristics of your vehicle change. The other
braking and driving systems still function normally.
I
Anti-Lock Brake System (ABS)
ABS prevents the wheels from locking at any speed
above about 5 mph (8 km/h), regardless of road
surface conditions. The vehicle remains steerable even
if the brakes are applied fully.
A light vibrating of the steering wheel and pulsating of
the brake pedal indicate that the ABS is working.
On slippery road surfaces, the ABS will respond even
with light brake pedal pressure because of the
increased likelihood of locking wheels. The pulsating
brake pedal can be an indication of hazardous road
conditions and works as a reminder to take extra care
while driving.
WARNING!
If the ABS indicator lamp- does not go out or
lights up again while driving, the ABS is malfunc-
tioning. If ABS malfunctions, the other driving
safety systems are deactivated. The vehicle’s brak-
ing characteristics may be affected. There is an in-
creased risk that your vehicle could skid in the
event of sharp braking. Have the malfunction
traced and repaired without delay by an autho-
rized Sprinter Dealer.
Adapt your speed and driving style to the
prevailing road, traffic and weather conditions.
Driving too fast increases the risk of an accident.

166 STARTING AND OPERATING
WARNING!
Do not reduce the force applied to the brake pedal if
it is necessary to brake the vehicle further. This will
negate the main benefit of ABS – the ability to brake
without affecting the steerability of the vehicle.
In the event of an emergency stop, fully depress
the brake pedal. Do not pump the brake pedal,
rather use firm, steady brake pedal pressure.
Pumping the pedal defeats the purpose of ABS
and significantly reduces braking effectiveness.
WARNING!
Anti-lock brake system (ABS) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase braking or steering efficiency
beyond that afforded by the condition of the vehi-
cle brakes and tires or the traction afforded.
The ABS cannot prevent accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or
hydroplaning. Only a safe, attentive, and skillful
driver can prevent accidents.
The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety
or the safety of others.
Adapt your speed and driving style to the
prevailing road, traffic and weather conditions.
Driving too fast increases the risk of an accident.

170 STARTING AND OPERATING
Acceleration Skid Control (ASR)
ASR makes it possible to pull away and accelerate on a
slippery surface. A spinning wheel is braked and its
tractive power is transferred to the wheel with full
grip.
The acceleration skid control (ASR) improves driving
stability at all speeds only on vehicles of the chassis
and cargo/passenger vans type 3500 C/HC/SHC
(without ESP
®).
The engine’s torque is limited to improve driving
stability. When this is happening, the warning
lampv in the speedometer flashes.
If the road surface is not capable of providing traction,
bearing in mind the tires, load and grade, it may not be
possible to pull away even with ASR.
If wheels with tires of a different size than those offered
by an authorized Sprinter Dealer are used, the correct
operation of the ASR cannot be guaranteed.
WARNING!
ASR cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded.
The ASR cannot prevent accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or
hydroplaning. Only a safe, attentive, and skillful
driver can prevent accidents.
The capabilities of an ASR equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety
or the safety of others.
If the ASR function is used for a prolonged period
of time, the rear axle brakes may fail due to
overheating.
If the vehicle is to be towed away with the front
wheels clear of the ground, or if the brakes are to
be tested on a brake dynamometer, do not pull the
key in position 2 in the ignition lock, because the
drive wheels could lock.

Deactivating the Acceleration Skid Control (ASR)
See Section 4, Understanding Your Instrument Panel,
for switch locations.
When driving with snow chains, in
deep snow, or on sand or gravel, it
can be beneficial to deactivate the
acceleration skid control (ASR).
The engine’s torque is then no longer
limited and the drive wheels are free
to spin, which can help them cut into
loose surfaces.
The ASR can only be shut off with the engine running.
If the engine is shut off with the ASR deactivated, the
ASR is automatically re-activated after the engine is
started again.Vehicle Type 2500 only:
If there is a danger of skidding, and/or starting at a
speed of 38 mph (60 km/h) ESP
® activates ASR
automatically.
WARNING!
On a slippery road surface if both drive wheels
start to spin there is a risk of skidding. Adapt your
speed and driving style to the prevailing road,
traffic and weather conditions.
P54.25-0294-20
WARNING!
Vehicle type 2500 only:
Even when ASR is deactivated, ESP
® remains
active and regulates braking to improve stability
as necessary. The warning lampv flashes in
the speedometer.
The danger of your vehicle’s brake system
overheating and being damaged is increased
during long, demanding application of the
brakes. Furthermore, an overheated brake system
could result in a longer stopping distance.
Thus, only deactivate ASR if it is absolutely
necessary.
Page 172 of 330

172 STARTING AND OPERATING
To deactivate the ASR:
Press the upper section of the switch – the warning
lamp v in the speedometer lights up.
Traction control continues to cut in if, for example, a
wheel on one side of the vehicle reaches its limit of
adhesion. The wheel is then braked to increase the
vehicle’s overall traction.
The warning lamp v will flash in the speedometer
at any speed when a tire reaches its limit of adhesion
and spins.
To activate the ASR:
Press the upper section of the switch again – the
warning lamp v in the speedometer goes out.Brake Assist System (BAS) (vehicle type 2500 only)
The Brake Assist System (BAS) operates in emergency
situations. If you apply the brakes very quickly, the
BAS automatically provides full brake boost, thereby
potentially reducing braking distance.
Apply continuous full braking pressure until the
emergency braking situation is over.
The ABS will prevent the wheels from locking.
When you release the brake pedal, the brakes function
again as normal. The BAS is then deactivated.
WARNING!
If the indicator lamp k remains on, a malfunc-
tion may not only have occurred in the ASR sys-
tem but also in the BAS.
The handling and braking characteristics of your
vehicle change. Drive with extra caution.
Have the malfunction traced and repaired as soon
as possible by an authorized Sprinter Dealer.

Indicator Lamp Electronic Stability Program
(ESP®) (vehicle type 2500 only)
When the key is in position 2 in the ignition lock, the
ESP
® indicator lamp will light up in the
instrument cluster as a function check. It goes out
when the engine is running.
If the indicator lamp remains on or lights up when
the engine is running, the electronic stability program
(ESP
®) is malfunctioning and switched off
automatically. The engine’s power output may be then
reduced.
WARNING!
The Brake Assist system (BAS) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase braking efficiency beyond that
afforded by the condition of the vehicle brakes
and tires or the traction afforded.
The BAS cannot prevent accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or
hydroplaning. Only a safe, attentive, and skillful
driver can prevent accidents.
The capabilities of an BAS equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety
or the safety of others
.
Adapt your speed and driving style to the
prevailing road, traffic and weather conditions.
Driving too fast increases the risk of an accident.

174 STARTING AND OPERATING
NOTE: If the ABS is malfunctioning or the voltage in
the vehicle’s electrical system drops below 10 volts, the
indicator lamp will also light up in the instrument
cluster and the ESP
® will be deactivated. The indicator
lamp will go out as soon as the voltage reaches this
level again or the ABS is operational again – the ESP
®
is then reactivated.Electronic Stability Program (ESP
®) (vehicle type
2500 only)
The Electronic Stability Program (ESP
®) monitors the
vehicle’s traction (force of adhesive friction between
the tires and the road surface) and handling.
The ESP
® recognizes when a wheel is spinning or if the
vehicle starts to skid. By applying brakes to the
appropriate wheel and by limiting engine output, the
ESP
® works to stabilize the vehicle. The ESP® is
especially useful while driving off and on wet or
slippery road surfaces.
The warning lamp v in the speedometer flashes
when the ESP
® is engaged, refer also to "Warning
Lamp Acceleration Skid Control (ASR) and Electronic
Stability Program (ESP
®)".
If wheels with tires of a different size than those offered
by an authorized Sprinter Dealer are used, the correct
operation of the ESP
® cannot be guaranteed.
WARNING!
If the ESP® indicator lamp remains on, the
electronic stability program (ESP®) is malfunc-
tioning. The vehicle stability will no longer be au-
tomatically regulated in good time.
The danger that your vehicle breaks into a skid, is
increased in certain driving situations. Drive with
extra caution.
Have the ESP
® repaired as soon as possible by an
authorized Spinter Dealer.
