The expansion tank is in the engine com-
partment. Only add coolant with the vehi-
cle standing on a level surface and with the
engine switched off. The coolant tempera-
ture must have dropped below 122 °F
(50 °C).1Coolant tank cap

\1Slowly unscrew cap1 counterclock-
wise to reduce excess pressure.
\1Continue turning the cap and remove
it.
\1Add coolant as far as the MAX mark.
\1Twist cap1 back on.
For coolant specifications, see "Service
products and capacities" (\2page 355).Environmental note
H
When adding oil, take care not to spill any.
No engine oil must be allowed to enter sew-
age systems, surface water, ground water or
soil.
You would otherwise be damaging the envi-
ronment.
Dispose of engine oil in an environmentally
responsible manner. Comply with the manu-
facturer’s instructions.Coolant
Warning
G
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 tem-
perature.
Wear gloves and eye protection. Only open
the coolant expansion tank when the cool-
ant temperature is less than 122 °F (50 °C).

Warning
G
Coolant contains glycol and is therefore tox-
ic. Do not swallow coolant. Consult a doctor
immediately if any coolant is swallowed.
Do not allow coolant to come into contact
with your skin, eyes or clothing. In the event
of contact with the eyes, rinse them thor-
oughly with clean water. Clean skin and
clothes immediately with soap and water.
Change out of soiled clothing without delay.

The reservoir is in the engine compart-
ment. Check the brake fluid level:

The brake fluid level must be between the
MIN and MAX marks.
!
CAUTION
Check the cooling and heating systems
regularly for leaks. If a large quantity of
coolant is lost, have the cause traced
and rectified at an authorized Sprinter
Dealer.
Brake fluid
iThere is usually a notice in the engine
compartment to remind you when the
next brake fluid change is due.
N20.30-2063-31
!
CAUTION
Brake fluid corrodes paintwork. If
brake fluid comes into contact with the
paintwork, immediately rinse with wa-
ter.
If the brake fluid does not reach the
MIN mark, the vehicle’s hydraulic sys-
tem could be malfunctioning. Do not
add brake fluid under any circumstanc-
es. This will not solve the problem.
Do not drive any further.
Have the system checked immediately
at an authorized Sprinter Dealer.
Warning
G
Brake fluid is hazardous to health. Do not
swallow brake fluid. Consult a doctor imme-
diately if any brake fluid is swallowed.
Brake fluid must not come into contact with
the skin, eyes or clothing. Wash affected ar-
eas with plenty of clean water and consult a
doctor immediately if necessary.

For specifications of brake fluid, see
"Service products and capacities"
(\2page 362).The windshield washer reservoir is in the
engine compartment. It holds approx.
7.4 US qt (7.0 l).
On vehicles with a headlamp cleaning sys-
tem, this is also supplied from the wind-
shield washer reservoir.

Add windshield washer fluid concentrate
to the water all year round.Adapt the mixing ratio to the outside tem-
perature. Use:
\4Summerwash to protect against
smearing at temperatures above freez-
ing.
\4Winterwash when there is a risk of frost
so that the water does not freeze onto
the windshield.
\1Mix the windshield washer fluid in a
container and in the specified propor-
tions.
\1Remove cap3.
\1Fill up the windshield washer fluid.
\1Press cap3 back on.You should always wear eye protection and
gloves when you are adding brake fluid.
Only store brake fluid in its closed original
container and keep out of the reach of chil-
dren. Comply with safety regulations when
handling brake fluid.Warning
G
If the boiling point of the brake fluid is too
low, vapor pockets may form in the brake
system when the brakes are applied hard
(e.g. when driving on long downhill stretch-
es). This has a detrimental effect on braking
efficiency, which could increase the stop-
ping distance. This increases the risk of an
accident.
Have the brake fluid replaced every
two years.
