168 STARTING AND OPERATING
If the indicator lampk remains on or lights up
when the engine is running, the acceleration skid
control (ASR) or the brake assist system (BAS)
1 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 lampk will also light up in the instrument
cluster and the ASR and the BAS
1 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
1 are then reactivated.
If a malfunction is present in the acceleration skid
control (ASR), the engine’s power output may be
reduced.
1Vehicle type 2500 only
WARNING!
If the indicator lampk remains on, the acceler-
ation skid control (ASR) or the brake assist system
(BAS)
1 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.

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.

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.

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.

Information placard, refer to "Tires and Wheels". Not
all M+S rated radial-ply tires provide special winter
performance. Make sure the tires you use show M+S
and the mountain/snowflake marking.on the tire
sidewall. These tires meet specific snow traction
performance requirements of the Rubber
Manufacturers Association (RMA) and the Rubber
Association of Canada (RAC) and have been designed
specifically for use in snow conditions. Use of winter
tires is the only way to achieve the maximum
effectiveness of the ABS and ESP
® in winter operation.
For safe handling, make sure all winter tires mounted
are of the same make and have the same tread design.
Always observe the speed rating of the winter tires
installed on your vehicle. If the maximum speed for
which your tires are rated is below the speed rating of
your vehicle, you must place a notice to this effectwhere it will be seen by the driver. Such notices are
available at your tire dealer or any authorized Sprinter
Dealer.
While studded tires improve performance on ice, skid
and traction capability on wet or dry surfaces may be
poorer than that of non-studded tires. Some states
prohibit studded tires; therefore, local laws should be
checked before using these tire types.
SNOW CHAINS
Use "Class U" chains , or other traction aids that meet
SAE Type "U" specifications.
WARNING!
Winter tires with a tread depth under 1/6 in (4 mm)
must be replaced. They are no longer suitable for
winter operation.
WARNING!
If you use your spare tire when winter tires are fit-
ted on the other wheels, be aware that the differ-
ence in tire characteristics may very well impair
turning stability and that overall driving stability
may be reduced. Adapt your driving style accord-
ingly.
Have the spare tire replaced with a winter tire at
the nearest authorized Sprinter Dealer.

Hydraulic Brake System, Clutch Mechanism Fluid
Level
1. Brake fluid reservoir
Brake fluid level must be between the MIN and MAX
marks in the reservoir (1).
If the brake fluid is below the MIN mark, there may be
a fault in the hydraulic system. Have the system
checked as soon as possible by an authorized Sprinter
Dealer.Brake fluid
Refer 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 System
The 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.
