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.

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.
CAUTION!
Delaying draining of the fuel filter for a
considerable time after the indicator lamp lights
up may lead to engine damage.

Bleeding the Diesel Fuel System
The diesel fuel system must be 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.PERMISSIBLE ROOF LOAD
The maximum permissible roof load is:
Vehicles with low roof 660 lbs (300 kg)
Vehicles with high roof 330 lbs (150 kg)
The weight of any load carried on the roof,
including the roof rack, must not exceed the
maximum permissible roof load.
LOADING THE VEHICLE
Two labels on the vehicle show how much weight it
may properly carry.
The Tire and Loading Information placard can be
found on the driver’s door B-pillar. This placard
tells you important information about the number
of people that can be in the vehicle and the total
weight that can be carried in the vehicle. It also
contains information on the proper size and
recommended tire inflation pressures for the
original equipment tires on the vehicle.
The Certification Label can be found below the
driver’s seat on an outward facing position of the
mounting pillar. It tells you about the gross weight

*Vehicle Type 2500 onlyIf the Engine is Damaged
For towing distances up to 30 miles (about 50 km)
Shift gear 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.
If the Front Axle is Damaged
Raise the front axle.
Observe the same towing restrictions as for engine
damage.
If the Rear Axle is Damaged
Raise the rear axle.
NOTE: Comply with local legal regulations regarding
towing vehicles.
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
®)*.

environmentally responsible manner. Comply with
applicable bars and regulations.
EMISSION RELATED COMPONENT WARRANTY
STATEMENT
The Manufacturer warrants to the original and each
subsequent owner of a Sprinter heavy-duty on
highway diesel engine that:
(1) the engine was designed, built and equipped so as
to conform at the time of sale with the applicable
regulations adopted by the Federal Environmental
Protection Agency, and
(2) the emission control system of such engine is free
from defects in materials and workmanship which
would cause it not to conform with those regulations
for a period of use of five years or 100 000 miles or
3 000 hours of engine operation, whichever occurs
first.REGULAR CHECKS
WARNING!
When the hood is open, there is a risk of injury
due to very hot engine components.
When the engine is running or the key is in posi-
tion 2 in the ignition lock, there is a risk of injury
due to moving engine components and the electri-
cal system.
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 vehicle and
do not open the hood until the engine has cooled.
If necessary, call the fire department.
Page 264 of 330

264 MAINTAINING YOUR VEHICLE
Open the hood.
At first, only turn the pressure cap on coolant
reservoir to the first detent to release the pressure
from the cooling system. Only then should the
pressure 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
(1.5 cm) above the base area which is visible
through the filler opening.
Replace and tighten the pressure cap on coolant
reservoir.
If a large quantity of coolant has been lost, or if smaller
amounts are lost at regular intervals, have the engine
cooling system examined by an authorized Sprinter
Dealer.
For coolant composition and water quality, contact
your Sprinter Dealer.
WARNING!
Do not spill antifreeze on hot engine parts. Anti-
freeze 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.

266 MAINTAINING YOUR VEHICLE
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 BatteryReconnecting the Battery
Vent tube (1)
Fitting (2)
All electrical consumers must be switched off. First
connect and tighten the positive terminal clamp, then
the negative terminal. Make sure that the terminal
clamps are not switched.
NOTE: If batteries have to be replaced, only use
batteries with a central vent cap as this will prevent
corrosion damage.
Connect the battery vent tube (1) to the fitting (2).
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.
