Residual Engine Heat Utilization (REST)
The REST switch (1) is located on the
center section of the dashboard.
The residual engine heat utilization
system can be used to keep the
vehicle interior warm for some time
after the engine is switched off.
Turn the key to position 0 in the ignition lock or
remove it altogether.
To switch on:
1. Press the residual engine heat utilization switch (1),
the indicator lamp (2) lights up.
The blower will run at speed 1 regardless of the
setting of the airflow control.
2. Set the temperature control as required, refer to
"Heating, Ventilation".
To switch off:
Press the residual engine heat utilization switch (1)
again, the indicator lamp (2) goes out.The residual engine heat utilization is automatically
switched off if:
1. If the key is turned to position 2 in the ignition lock,
2. after about 30 minutes,
3. if the battery voltage is too low.
A IR CONDITIONING, REGULA TED (OPTIONA L)
The air conditioning switch (1) is
located on the center section of the
dashboard.
The air conditioning can be used to
cool or dehumidify the air in the
vehicle. The selected temperature is
reached as quickly as possible and
then held constant.
The air conditioning is only operational when the
engine is running.

116 UNDERSTANDING YOUR INSTRUMENT PANELTo switch on:
Press switch (1), the indicator lamp (2) in the switch
lights up.
To switch off:
Press switch (1) again, the indicator lamp (2) goes out.
NOTE: Run the air conditioning at least once a month
for about 10 minutes.
It is possible that the air conditioning will
automatically switch off at outside temperatures below
41 °F (+5 °C). Dehumidification is then also not
possible.
Condensation may emerge from the underside of the
vehicle.
The air conditioner only uses the refrigerant R-134a.
This refrigerant does not damage the earth’s ozone
layer.
Climate Control (on Vehicles with A ir Conditioning)1. Set the airflow control (2) to position 1 to 4.
Position 4 gives maximum cooling.
2. Set the temperature switch (1) as required (The
interior temperature is regulated by the
Tempmatik. If the interior temperature falls below
the preset temperature, warm air is automatically
supplied).
3. Set the air distribution control (3) to h.
4. To switch on air conditioning, press switch (4).
WARNING!
While driving, deactivate the air conditioning
only temporarily to prevent window fogging.

122 UNDERSTANDING YOUR INSTRUMENT PANELHEA TER BOOSTER
The switch (1) for activating the
heater booster system is located in
the center section of the dashboard.
The heater booster system can be
switched on while the vehicle is
being driven to help the engine to
reach its normal operating
temperature more quickly, which
will help to heat up the passenger compartment as
quickly as possible when the heating is switched on.To switch on with the engine running:
Press switch (1), the indicator lamp (2) lights up.
To switch off:
Press switch (1) again or switch the engine off. The
heater booster will then switch to run-on mode (about
2minutes).
NOTE: When the vehicle is being driven and a coolant
temperature of over 185 °F (+80 °C) is reached, the
heater booster system will switch to regulation mode.
If the coolant temperature drops to below 167 °F
(+75 °C) with the heater booster system switched on,
heat output is increased again.
If the key is turned to position 0 in the ignition lock
(run-on for about 2 minutes), the last setting selected at
switch (1) is retained when the engine is restarted
(memory function).
The operation of the heater booster system is usually
not required at outside temperatures above 41 °F
(+5 °C).

Press the upper section, the left-hand indicator lamp in
the switch lights up.

Press the lower section, the right-hand indicator lamp
in the switch lights up.
To switch off :
Press the switch to the middle position.
Operation is only possible when the key is turned to

A UXILIA RY HEA TER – TIPS FOR COPING WITH
PROBLEMSThe heater either does not switch on or automatically
switches off:
Insufficient fuel, fill up the fuel tank. Start up heater
several 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.

136 STARTING AND OPERATING1. Apply the parking brake.
2. Automatic transmission, shift selector lever to "P"
or "N" position, refer to "Automatic Transmission".
3. Do not depress the accelerator pedal.
4. Turn the key to position 2 in the ignition lock.
The preheater indicator lampq lights up.5. Turn the key clockwise to the stop as soon as the
preheater indicator lamp
q
goes out.
If the engine is at its normal operating temperature,
the preheater indicator lamp will only light up briefly.
Release the key as soon as the engine is running.
NOTE: The key must be returned to position 0 in the
ignition lock before repeating the starting procedure.
If the displayÁ lights up alternately withî in
the multi-function display, there is an immobilizer
malfunction or the key used has not been
programmed.
The: engine oil level warning lamp and the#
battery charge warning lamp must go out after the
engine is started.
If either lamp remains on, stop the engine at once and
have the cause traced and repaired by an authorized
Sprinter Dealer.
During the trip, check the displays and the warning/
indicator lamps in the instrument cluster at regular
intervals.
For instrument cluster and indicator lamps.Maximum Engine SpeedThe maximum engine speed for all vehicles is
4,200 rpm.

140 STARTING AND OPERATINGNOTE: After selecting any driving position from "N"
or "P", wait a moment to allow the gear to fully engage
before accelerating, especially when the engine is cold.A ccelerator PositionPartial throttle, for early upshifting and normal
acceleration
Full throttle, for later upshifting and rapid acceleration
Kickdown, (depressing the accelerator beyond full
throttle) for downshifting to a lower gear and
maximum acceleration. Once the desired speed is
attained, ease up on the accelerator, the transmission
shifts up again.StoppingFor brief stops, such as at traffic lights, leave the
transmission in gear and hold vehicle with the service
brake.
For longer stops with the engine idling, shift into "N"
or "P" and hold the vehicle with the service brake.
When stopping the vehicle on an uphill grade, do not
hold it with the accelerator, use the brake. This avoids
unnecessary transmission heat build up.
ManeuveringTo maneuver in tight areas, such as when pulling into
a parking space, control the vehicle speed by gradually
releasing the brakes. Accelerate gently and never
abruptly step on the accelerator.
To rock a vehicle out of soft ground (mud or snow),
alternately shift from forward to reverse, while
applying slight partial throttle.
WARNING!
Getting out of your vehicle with the selector lever
not fully engaged in position "P" is dangerous.
Also, when parked on an incline, position "P"
alone may not prevent your vehicle from moving,
possibly hitting people or objects.
Always set the parking brake in addition to
shifting to position "P".
When parked on an incline, also turn front wheel
against curb.

NOTE: On long and steep downhill slopes, reduce the
load on the brakes by shifting down a gear to utilize the
braking effect of the engine.
To prevent corrosion on the brake pads, after driving
on very wet roads, especially if road salts have been
used, apply brakes before parking the vehicle. The heat
generated will help to dry the brake disks.
Brake Pad Wear IndicatorWhen the key is turned to position 2 in the ignition
lock, the indicator lamp2 in the instrument cluster
lights up for about 2 seconds. It must go out when the
engine is running.
If the 2indicator lamp lights up while the engine is
running, the brake pads are worn almost to their limit.
Have the brake system examined as soon as possible
by an authorized Sprinter Dealer.
