If the indicator lamp k remains on or lights up
when the engine is running, the acceleration skid
control (ASR) or the brake assist system (BAS) is
malfunctioning.
Then the ASR will be switched off automatically.
NOTE: If the ABS is malfunctioning or the voltage in
the vehicle’s electrical system drops below 10 volts, the
indicator lamp k will also light up in the instrument
cluster and the ASR and the BAS 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 ASR and the BAS are then reactivated.
If a malfunction is present in the acceleration skid
control (ASR), the engine’s power output may be
reduced.
WARNING!
If the indicator lamp k remains on, the acceler-
ation skid control (ASR) or the brake assist system
(BAS) is malfunctioning .
Your vehicle’s handling characteristics can
change. Drive with extra caution.
Have the malfunction traced and repaired as soon
as possible by an authorized Sprinter Dealer.

168 STARTING AND OPERATINGDeactivating 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 lamp
v 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.

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.

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 malfunction-
ing. The vehicle stability will no longer be auto-
matically 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.

Brake fluidRefer to the "Recommended Fluids" chart later in this
section for recommended brake fluids.
In the course of its service life, the boiling point of the
brake fluid will fall due to the continuous absorption of
moisture from the atmosphere.
If the brakes are placed under heavy loads (e.g., on
steep hills) bubbles of steam can then form in the brake
system.
This will adversely affect the brakes' effectiveness.Engine Cooling SystemThe use of aluminum components in Sprinter engines
requires that anticorrosive/antifreeze specifically
formulated to protect aluminum parts be used. The
factory approved Service Products are suitable for
Sprinter engines and can be mixed with the original
anticorrosion/antifreeze filled in at factory.
Cooling system design and anticorrosion/antifreeze
agent used stipulate the replacement interval for the
coolant solution in your vehicle. Please observe the
replacement interval specified in the Service Booklet
for your vehicle.
Failure to use MB 325.0 an ticorrosion/antifreeze and/or
equivalent to DaimlerChrys ler material standard MS-
9769 and/or adhere to the specified replacement interval
may result in a significantly shortened service life.For coolant composition and water quality, contact
your authorized Sprinter Dealer.Engine CoolantThe coolant is a mixture of water and a corrosion
inhibitor/antifreeze additive. Within the cooling
system, the corrosion inhibitor/antifreeze ensures
anti-corrosion protection
antifreeze protection
a higher boiling point.
The coolant added in the factory ensures adequate
antifreeze and anti-corrosion protection.
Refer to the "Recommended Fluids" chart for coolant
recommendations.
For reasons of anti-corrosion protection and to increase
the boiling point, the cool ant added to the cooling
system is designed for all year round operation – even
in countries with high prevailing temperatures.
