AUXILIARY HEATER – TIPS FOR COPING WITH
PROBLEMS
NOTE: After three successive attempts to start the
heater, a malfunction will be recorded in the integrated
diagnostic system and no further operation on
auxiliary heater will be available (lock-out). The work
to annul the lock-out must be carried out at an
authorized Sprinter Dealer.
The heater either does not switch on or automatically
switches off:
 Insufficient fuel, fill up the fuel tank. Start up heater
two times, until the fuel lines are filled.
 The auxiliary heater will automatically switch off if
the fuel level is under about 4 US gal (15 l).
 The fuses in the fuse box are damaged. Electric
fuses.
 The battery voltage is too low, an undervoltage
protector switches off the heater if the battery
voltage falls below about 10 volts.The heater motor does not run
 The battery voltage is too low, check the battery.
Batteries.
 The fuses in the fuse box are damaged.
Electric fuses.
 The heater motor is damaged.
Overheating
 The air channels are clogged.
The heater can be restarted once the fault has been
repaired. When this is done, the heater should be
switched on and off.
 The heater will remain switched off after it has been
overheated a number of times (about 10 times in
succession). Have the fault repaired by an
authorized Sprinter Dealer.
NOTE: Repairs should only be made by an authorized
Sprinter Dealer.

158 STARTING AND OPERATING
Protect sharp edges with padding.
 Check the tire pressures after loading the vehicle.
For passenger vans:
 Do not stack loads higher than the upper edge of the
backrests.
 Always place the load against the backrests of the
seat benches.
 Whenever possible, transport loads behind seats
that are not occupied.
 Distribute the load in such a way that the
permissible axle loads are not exceeded when the
vehicle is equipped with the maximum number of
seats. Loading the luggage compartment up to the
maximum payload would cause the permissible
rear axle load to be exceeded.BRAKES
Service Brake
WARNING!
When the engine is not running, the brake and
steering systems are without power assistance.
Under these circumstances, a much greater effort
is necessary to stop or steer the vehicle.
After driving in heavy rain for some time without
applying the brakes or through water deep
enough to wet brake components, the first
braking action may be somewhat reduced and
increased pedal pressure may be necessary. Be
sure to maintain a safe distance from vehicles in
front.
Resting your foot on the brake pedal will cause
excessive and premature wear of the brake pads.
It can also result in the brakes overheating,
thereby significantly reducing their effectiveness.
It may not be possible to stop the vehicle in
sufficient time to avoid 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.

Ribbed V-belt (not part of factory package) (2)
Tensioner pulley (3)
Support (4)
Unit (not part of factory package) (5)
NOTE: When retrofitting a unit pay attention to the
running direction of the engine.
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.

226 STARTING AND OPERATING
WARNING!
Take into consideration that when towing a trail-
er, the handling characteristics are different and
less stable from those when operating the vehicle
without a trailer.
It is important to avoid sudden maneuvers.
Sudden maneuvers may lead to loss of control
over the vehicle-trailer combination. This could
cause an accident resulting in property damage or
injury to you or others.
CAUTION!
If the transmission hunts between gears on
inclines, manually shift to a lower gear (select
"4",
"3", "2" or"1"). A lower gear and reduction of
speed reduces the chance of engine overloading
and / or overheating.
When going down a long hill, shift into a lower
gear and use the engine’s braking effect. Avoid
riding the brakes, thus overheating the vehicle
and trailer brakes.
If the engine coolant rises to an extremely high
temperature (coolant temperature needle
approaching the red zone) when the air
conditioner is on, turn off the air conditioner.
Engine coolant heat can be additionally vented by
opening the windows, switching the climate
control fan speed to high and setting the
temperature control to the maximum hot position.
