Acceleration Skid Control (ASR) Warning Lamp
and Electronic Stability Program (ESP®)* – if
equipped
When the key is in position 2 in the ignition lock, the
warning lampv in the speedometer will light up
for about 2 seconds. It must go out when the engine is
running.
The warning lampv flashes when:
The ASR or ESP
®* is activated.
The drive wheels spin with the ASR shut off.
*Vehicle type 2500 onlyThe warning lamp v lights up when the ASR is
shut off.
Deactivate the acceleration skid control, refer to
"Deactivating Acceleration Skid Control (ASR)".
WARNING!
If the warning lampv in the speedometer
lights up or flashes:
Do not deactivate the acceleration skid control
(ASR).
Only depress the accelerator pedal as far as
necessary when pulling away.
Ease off on the accelerator pedal when driving at
a steady speed.
Adapt your speed and driving style to the
prevailing road, traffic and weather conditions.
Failure to heed these warnings could cause the
vehicle to enter a skid and may result in 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.

System (BAS)
".
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.

WARNING!
ESP® cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded.
The ESP
® 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 ESP
® 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 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 put the key
in position 2 in the ignition lock because the ESP
®
would engage the brakes to stabilize the vehicle.
If the ESP® function is used for a prolonged
period of time, the rear axle brakes may fail due to
overheating.

176 STARTING AND OPERATING
STEERING
When the engine is not running, there is no power
assistance for the steering. Greater force will be
required to steer the vehicle.
WHEELS AND TIRES
The tires on a new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The
vehicle manufacturer strongly recommends to use tires
equivalent to the originals in size, quality and
performance when replacement is needed. Refer to the
Tire and Loading Information placard on the driver’s
door B-pillar for the size designation of your tire.
The service description and load identification will be
found on the original equipment tire. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your Sprinter vehicle.Contact an authorized Sprinter Dealer or an
authorized tire dealer with any questions you may
have on tire specifications or capability.
CAUTION!
Power take off must not exceed 10 kW. Exceeding
the power take off may cause damage to the
auxiliary drive and/or ribbed V-belt.
WARNING!
Only use tires which have been tested and ap-
proved for your Sprinter vehicle by the vehicle
manufacturer. Tires approved by the vehicle man-
ufacturer are developed to provide best possible
performance in conjunction with the driving safe-
ty systems on your Sprinter vehicle such as ABS or
ESP
®.
Using tires other than those approved by the
vehicle manufacturer may result in damage that is
not covered by Warranty.
