Push hood catch release handle 0047
upwards. X
Swing the hood upwards until support strut
008A engages and the hood is supported.
Closing the hood G
Warning
When closing the hood be careful that nobody
becomes trapped.
X Lift the hood slightly.
X Press support strut 008A towards the back.
! When you press the support strut back,
make sure that you do not press it against
the detent position and cause it to bend.
X Lower the hood and let it drop shut from a
height of approximately 1 ft (30 cm).
The hood engages audibly. If the hood can
be raised slightly, it is not properly
engaged.
X If
the hood is not properly engaged, open it
once more and
allow it to drop shut from a
slightly greater height.
! Do not use your hands to push the hood
down. You could damage it otherwise. Maintenance points under the hood

Only add coolant

with the vehicle standing on
a level surface and with the engine switched
off. The coolant temperature must have
dropped below 122 ‡ (50 †). G
Warning
When opening the coolant expansion tank,
there is a risk of scalding from hot coolant
spraying out. The cooling system and the
coolant expansion tank

are pressurized when
the engine is at normal operating
temperature. Wear gloves and eye protection.

Operation
Z

Only open the coolant expansion tank when
the coolant temperature is below 122 ‡
(50 †).
G
Warning
Coolant contains glycol and is therefore toxic.
Do not swallow the coolant. See a doctor
immediately if you swallow coolant.
Make sure that coolant does not come into
contact with skin,

eyes or clothing. In case of
contact with eyes, rinse immediately with
plenty of clean water. Clean affected areas of
skin and clothing with soap and water
immediately. Change any affected clothing
immediately.
X Slowly turn cap 0046 counter-clockwise and
allow the excess pressure to escape.
X Turn cap 0046 further and remove it.
X Add coolant until it is at the MAX mark.
Observe the correct coolant mixture ratio
and the required water quality
(Y page 160).
X Replace cap 0046 and tighten
it until the stop.
! Check the cooling and heating system
regularly for leaks.
If a large quantity of coolant is lost, have
the cause traced

and rectified at a qualified
specialist workshop, e.g. an authorized
Sprinter Dealer. Clutch mechanism and brake system
G
Warning
Brake fluid is hazardous to health. Do not
swallow brake fluid.

See a doctor immediately
if you swallow brake fluid.
Make sure that brake fluid does not come into
contact with skin, clothing or eyes. Rinse
affected areas with plenty of clean water and
consult a doctor if necessary.
Always wear gloves and eye protection when
topping up brake fluid. Store brake fluid only in the original closed
container and keep it out of the reach of
children. Comply with safety regulations
when handling brake fluid.
G
Warning
If the
boiling point of the brake fluid is too low,
vapor pockets may form in the brake system
when the brakes

are subjected to a heavy load
(e.g. on long downhill stretches). This would
impair braking efficiency. The vehicle's
stopping distance may then be longer. This
increases the risk of an accident.
Have the brake fluid renewed every two years.
The brake fluid reservoir is located in the
engine compartment.
Check the brake fluid level:
R regularly, e.g. weekly or when refueling
R only with the vehicle standing on a level
surface and with the engine switched off
! Brake fluid corrodes paint, plastic and
rubber. If paint, plastic or rubber has come
into contact with brake fluid, rinse with
water immediately. 0046
Brake fluid reservoir cap
The brake fluid level must be between the
MIN and
MAX marks.
! If the brake fluid does not reach the
MIN mark, the vehicle's hydraulic system
could be faulty. Do not add brake fluid
under any circumstances. This will not
rectify the malfunction.
Do not drive any further. 170

Never run the engine if the coolant level is too low. The engine
could overheat and be damaged.
X
Stop the vehicle as soon as possible, paying attention to road
and traffic conditions.
X Switch off the engine and let it cool down.
X Add coolant and be sure to observe the warning notes
(Y page 169).
X If you need to add coolant frequently, have the cooling system
checked at a qualified specialist workshop. 00AE
The red coolant
warning lamp
lights up while
the engine is
running. The coolant temperature is too high.

The red coolant
warning lamp
lights up while

If the vehicle is stopped after being subjected to extreme loads
(e.g. driving in mountainous terrain, trailer towing), the coolant

light up when the ignition is switched on or the
engine is restarted.
X Run the engine for approximately one minute at idling speed.
X Consult a qualified specialist workshop if the coolant warning
lamp remains lit. 00B7

20 When the coolant is being renewed, the coolant must contain 50 % by volume of anticorrosion/antifreeze
agent. This is equivalent to antifreeze protection down to –34.6 ‡ (–37 †). Do not exceed a ratio of
55 % by volume (antifreeze protection down to approximately –49.0 ‡ (–45 †). Heat dissipation is otherwise
insufficient. Observe the MB Specifications for Service Products, Sheet No. 310.1.
