For the indicator lamp k refer to
"Indicator Lamp
Acceleration Skid Control (ASR) and Brake Assist
System (BAS)
".
Indicator Lamp Electronic Stability Program (ESP)
(Cargo/passenger vans type 2500 C/HC/SHC 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.

STEERINGWhen the engine is not running, there is no power
assistance for the steering. Greater force will be
required to steer the vehicle.WHEELS AND TIRESCheck tires regularly for even tread wear, tread depth
(note legal requirements) and signs of external
damage.
Only use wheels and tires of the same size, make and
pattern.
Do not install tires that are not approved for the size
and type of wheel installed or the vehicle itself. Only
use those wheel sizes which were delivered to you by
your authorized Sprinter Dealer.
Use only wheels and tires which have been tested and
approved by the vehicle manufacturer.
Break in new tires at moderate speeds for a distance of
about 65 miles (about 100 km).
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.

174 STARTING AND OPERATING
BLEEDING DIESEL FUEL SYSTEMIf the fuel tank was run empty, the diesel fuel system
must be bled after refueling before starting the engine.– Turn the key in the ignition lock to position 2 for at
least 30 seconds.– Return the key to position 0.– Start the engine.
NOTE: Too many attempts to start the engine could
drain the battery. If the engine does not start after
several attempts, consult an authorized Sprinter
Dealer.
WARNING!
Possible tire damage resulting in serious personal
injury or death may occur if the vehicle’s electron-
ic speed controller is programmed at a speed
above the maximum speed allowed by the manu-
facturer of the specific tires mounted on the vehi-
cle. The maximum speed of the tires prescribed by
the tire manufacturer must be determined and ac-
curately programmed into the electronic speed
controller. The electronic speed controller must
never be programmed at a speed greater than the
maximum allowable tire speed as prescribed by
the manufacturer of the specific tires mounted on
the vehicle.

DRAINING FUEL FILTER WITH WATER
SEPARATOR1. Fuel filter
2. Drain hose
3. Water drain screw
The fuel filter (1) is located in the engine compartment.
NOTE: The fuel filter must be drained as soon as the
water in fuel indicator lamp lights up.NOTE: Prior to opening water drain screw (3), place a
suitable receptacle underneath the drain hose (2). Turn
water drain screw (3) on and off only by hand.
Diesel fuels and diesel fuel mixtures must be disposed
of properly; we recommend water be drained from fuel
filters by an authorized Sprinter Dealer.
Draining Fuel Filter
Stop the engine.
Shift gear selector lever to ‘‘P’’ position.
Open the hood.
Place a suitable receptacle underneath the drain
hose (2).
Turn the key in the ignition lock to position 2.
CAUTION!
Delaying draining of the fuel filter for a
considerable time after the indicator lamp lights
up may lead to engine damage.

176 STARTING AND OPERATING Open immediately the water drain screw (3) about 1
turn (counterclockwise) until fluid emerges. Ensure
that the fluid is collected in the receptacle.
Close the water drain screw (3) as soon as about 0.25
US qt (0.2 liters) are emerged.
After draining, return the key in the ignition lock to
position 0.
Dispose of the collected fluid in an environmentally
responsible manner.
If the filter is still saturated, drain the filter once
more.
After draining, the engine may run briefly but stall for
lack of fuel. If this occurs, bleed the system.
NOTE: Should the water in the fuel indicator lamp
still not go out after the fuel filter has been drained
twice, the cause should be examined by an authorized
Sprinter Dealer.
Bleeding the Diesel Fuel SystemThe diesel fuel system is bled before starting the
engine.
Turn the key in the ignition lock position 2 for at
least 30 seconds.
Return the key to position 0.
Start the engine three to four times. The engine
control unit indicator lamp± must go out.
NOTE: Too many attempts to start the engine could
drain the battery. If the engine does not start after
several attempts, consult an authorized Sprinter
Dealer.

If the Engine is DamagedFor towing distances up to 30 miles (about 50 km)
Shift selector lever to "N" position.
Do not exceed a towing speed of 30 mph (50 km / h).
For towing distances greater than 30 miles (about
50 km)
Remove the propeller shafts leading to the drive
axles.
The vehicle can be towed without restriction.If the Transmission is Damaged Remove the propeller shafts leading to the drive
axles.
WARNING!
Do not tow the vehicle if the key cannot be turned
in the ignition lock.
If the key cannot be turned, the ignition lock re-
mains locked and the vehicle cannot be steered.
With the engine not running there is no power
assistance for the braking and steering systems.
In this case, it is important to keep in mind that a
considerably higher degree of effort is necessary
to brake and steer the vehicle.
The vehicle must not be towed with the front axle
raised and the key in position 2 in the ignition
lock as the drive wheels could then lock due to the
acceleration skid control (ASR) or the optional
Electronic Stability Program (ESP).

214 MAINTAINING YOUR VEHICLE
Open the hood.
At first, only turn the radiator cap to the first detent
to release the pressure from the cooling system.
Only then should the radiator cap be removed
completely.
To add coolant:
If the engine is cold:
Add coolant until the coolant level reaches the base
area which is visible through the filler opening (area
moistened).
If the engine is already at its regular operating
temperature:
Add coolant until the coolant level is about 0.6 inch
WARNING!
In order to avoid any possibly serious burns:
If you see flames or smoke coming from the
engine compartment, or if the coolant
temperature gauge indicates that the engine is
overheated, do not open the hood. Move away
from the vehicle and do not open the hood until
the engine has cooled. If necessary, call the fire
department.
Do not remove pressure cap on coolant reservoir
if engine temperature is above 194 °F (+90 ×C).
Allow engine to cool down before removing cap.
The coolant reservoir contains hot fluid and is
under pressure.
Using a rag, slowly open cap approximately 1/2
turn to relieve excess pressure. If opened
immediately, scalding hot fluid and steam will
be blown out under pressure.
Do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which may
burn if it comes into contact with hot engine
parts.
Check coolant level only with the engine
switched off and the key in position 0 in the
ignition lock.

216 MAINTAINING YOUR VEHICLEBA TTERIESThe standard battery is located in the engine
compartment.The auxiliary battery is located underneath the front
passenger seat (optional equipment).
The battery will not achieve its maximum service life
unless it is kept adequately charged at all times. If the
vehicle is used primarily for short distances, or left
parked for lengthy periods, have the battery charge
checked more frequently.
Disconnecting the Battery
WARNING!
Failure to follow these instructions can result in
severe personal injuries and death.
Never lean over batteries while connecting, you
might get injured, if the battery explodes.
Battery fluid contains sulfuric acid. Do not allow
this fluid to come in contact with eyes, skin or
clothing. In case it does, immediately flush
affected area with water and seek medical help if
necessary.
A battery will also produce hydrogen gas, which
is flammable and explosive. Keep flames or
sparks away from battery, avoid improper
connection of jumper cables, smoking etc.
Use only impact-resistant batteries with a central
gas release cover to prevent corrosion damage and
to prevent occupants from caustic burns in the
event of an accident.
CAUTION!
Do not loosen or remove the battery terminal
clamps while the engine is running or the key is in
the ignition lock as this could damage electrical or
electronic equipment beyond repair. All electrical
consumers must be switched off.
Do not place any metal objects on the battery.
Doing so may cause a short-circuit.
Loosen and remove the negative terminal clamp
first, then the positive terminal.
Afterwards disconnect vent tube from the fitting.
