ELECTRIC BLOWER (OPTIONAL)See Section 4, Understanding Your Instrument Panel,
for switch locations.
The electric blower can be used to
aerate or deaerate the cargo area.
This feeds fresh air into the cargo
area or extracts warm air.
Deaeration:
Press switch upward.
Aeration:
Press switch downward.
To switch off:
Switch the airflow switch to the center position.
CAUTION!
Never operate the air conditioner for rear
passenger compartment without an air strainer.
Never install a damaged air strainer.
If the air strainer with visible contamination is
neither cleaned nor replaced, damage to the air
conditioner for rear passenger compartment may
result; such damage is not covered by the
Warranty.

Press the buttonH repeatedly until no memory is
displayed – no preselected time is activated.
Setting the Heating Period
Settings between 1 minute and 120 minutes may be set
for heating periods to run when the ignition is
switched off.
Do not switch on the heater.
Press the buttoný until the current heating period
begins to flash.
Use either the buttonýorþ to set the desired
heating period. The new heating period will be saved
as soon as the display disappears.
Auxiliary Heater Operation
The symbolö appears in the timer display as soon
as the heater is switched on. After about 20 to
50 seconds, the heater runs with the complete flow of
heat, so that the operating temperature is reached as
soon as possible.Heat operation:
Different operating conditions will be in effect
depending on the heat level required.
The integrated control unit adjusts the heat flow using
the following operating levels:
Water heater: High – Low – Off
Air heater: Power – High – Medium – Low – Off
Safety Equipment
For safety reasons, the heater will automatically switch
off if faults occur which cause the device to overheat.
Tips for Coping with Problems; refer to "Auxiliary
Heater – Tips for Coping with Problems".
The integrated control unit contains a diagnostic
system which detects and stores faults. The error can
be read by means of the vehicle diagnosis. If a fault
occurs while the heater is switched on, the
symbolö will flash and the error code for that fault
will be displayed in the timer.
The fault should be corrected as soon as possible by an
authorized Sprinter Dealer.Freightliner-all.book Pag e 128 Monday, December 1, 2003 2:54 PM

as the voltage reaches this level again
– the ABS is then
reactivated.
If ABS malfunctions, the other driving safety systems
are deactivated. The handling and braking
characteristics of your vehicle change. The other
braking and driving systems still function normally.
I
A nti-Lock Brake System (A BS)ABS prevents the wheels from locking at any speed
above about 5 mph (8 km/h), regardless of road
surface conditions. The vehicle remains steerable even
if the brakes are applied fully.
A light vibrating of the steering wheel and pulsating of
the brake pedal indicate that the ABS is working.
On slippery road surfaces, the ABS will respond even
with light brake pedal pressure because of the
increased likelihood of locking wheels. The pulsating
brake pedal can be an indication of hazardous road
conditions and works as a reminder to take extra care
while driving.
WARNING!
If the ABS indicator lamp- does not go out or
lights up again while driving, the ABS is malfunc-
tioning. If ABS malfunctions, the other driving
safety systems are deactivated. The vehicle’s brak-
ing characteristics may be affected. There is an in-
creased risk that your vehicle could skid in the
event of sharp braking. Have the malfunction
traced and repaired without delay by an autho-
rized Sprinter Dealer.
Adapt your speed and driving style to the
prevailing road, traffic and weather conditions.
Driving too fast increases the risk of an accident.

Electronic Brake Force Distribution (EBD)The electronic brake force distribution (EBD) prevents
the rear wheels from being overbraked when there is
little load on the rear axle or if there is not much friction
between the tires and road (e.g., if the road is wet).
A cceleration Skid Control Indicator Lamp (A SR)
and Brake A ssist System (BA S) if equippedWhen the key is in position 2 in the ignition lock, the
indicator lampk will light up in the instrument
cluster as a function check. It goes out when the engine
is running.
WARNING!
If the brake indicator lamp ;(-) does not
go out or lights up again while driving, the brake
fluid level may not necessarily have dropped be-
low the minimum filling capacity but a malfunc-
tion may have occurred in the EBD. In this case
continue driving, but with even greater care.
The wheels of the rear axle could lock if the
vehicle is braked hard. This could lead to a
skidding of the vehicle. Have the malfunction
traced and repaired without delay by an
authorized Sprinter Dealer.
Adapt your speed and driving style to the
prevailing road, traffic and weather conditions.
Driving too fast increases the risk of an accident.
