60 UNDERSTANDING THE FEATURES OF YOUR VEHICLEHOOD
To open:
1. Pull the release lever (1).
The hood then opens slightly and is restrained by
the safety catch.
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
position 2 in the ignition lock, there is a risk of
injury due to moving engine components and the
electrical system.
The engine is equipped with a transistorized
ignition system. Because of the high voltage it is
dangerous to touch any components (ignition coils,
spark plug sockets, diagnostic socket) of the
ignition system with the engine running, while
starting or if the ignition is on and the engine is
turned manually.
To help prevent severe personal injuries and death,
stay clear of moving parts when the hood is open
and the engine is running.
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.

Coolant Temperature GaugeThe coolant temperature is displayed when the key is
in position 2 in the ignition lock.
If corrosion inhibitor/antifreeze is present in the
correct concentration in the coolant, the coolant
temperature will be between 185 °F (+85 °C) and
250 °F (+120 °C), depending on operating conditions.
If the needle reaches the red section, do not continue to
drive the vehicle.For coolant level indicator lamp /, refer to "Coolant
Level Indicator Lamp".
NOTE: Coolant temperature display
°F in USA only.
°C in Canada only.
CAUTION!
Do not leave your vehicle unattended with the
engine running as you would not be able to react to
the temperature indicator if the engine overheats.
This would lead in turn to engine damage.

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.
To switch on at blower speed 2:
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
position 2 in the ignition lock.
NOTE: The auxiliary heat exchanger in the load
compartment should be switched off at coolant
temperatures below 176 °F (+80 °C) to quickly de-fog
and de-ice the windshield and front side windows.
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.

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.

212 MAINTAINING YOUR VEHICLEBrake fluidUse brake fluid approved to MB 331.0, or a DOT 4
brake fluid with: minimum dry boiling point (ERBP)
500
°F, minimum wet boiling point (WERBP)
356°F, maximum viscosity 1500 mm
2/s,
conforming to FMVSS116 and ISO 4925.
In the course of its service life, the boiling point of the
brake fluid will fall due to the continuous absorption of
moisture from the atmosphere.
If the brakes are placed under heavy loads (e.g., on
steep hills) bubbles of steam can then form in the brake
system.
This will adversely affect the brakes' effectiveness.
Engine CoolantThe coolant is a mixture of water and a corrosion
inhibitor/antifreeze additive. Within the cooling
system, the corrosion inhibitor/antifreeze ensures
 anti-corrosion protection
 antifreeze protection
 a higher boiling point.
The coolant added in the factory ensures adequate
antifreeze and anti-corrosion protection.
Use coolant approved to MB 325.0, such as Valvoline
GO5, or an equivalent Extended Life Coolant.
To avoid damage to the cooling system, only use
manufacturer approved corrosion inhibitor/
antifreeze additives.
Information on the corrosion inhibitor/antifreeze
additive is available from any Sprinter Dealer.
For reasons of anti-corrosion protection and to increase
the boiling point, the coolant added to the cooling
system is designed for all year round operation – even
in countries with high prevailing temperatures.
