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
temperature.
Wear gloves and eye protection. Only
open the coolant expansion tank when
the coolant temperature is less than
122 °F (50 °C).
Warning
G
Coolant contains glycol and is therefore
toxic. Do not swallow coolant. Consult a
doctor immediately if any coolant is swal-
lowed.
Do not allow coolant to come into contact
with your skin, eyes or clothing. In the
event of contact with the eyes, rinse them
thoroughly with clean water. Clean skin
and clothes immediately with soap and
water. Change out of soiled clothing with-
out delay.
!
CAUTION
Check the cooling and heating sys-
tems regularly for leaks. If a large
quantity of coolant is lost, have the
cause traced and rectified at an au-
thorized Sprinter Dealer.

On vehicles with a headlamp cleaning
system, this is also supplied from the
windshield washer reservoir.

to the water all year round.
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
stretches). This has a detrimental effect
on braking efficiency, which could in-
crease the stopping distance. This in-
creases the risk of an accident.
Have the brake fluid replaced every
two years.

Oil change, if the current engine oil
used has not been approved for win-

The antifreeze / anti-corrosion con-
centration in the coolant is checked

fuel for use at low outside temperatures
in the “Technical data” section
(

page 614).
Please also observe the information
about winter driving (
\2
page 406).
Winter tires should also be operated as
printed on the tire and loading informa-
tion placard

sure placard located on the driver’s door
B-pillar, refer to “Tires and wheels” (

page 362). Not all M+S rated radial-
ply tires provide special winter perfor-
mance. Make sure the tires you use
show M+S and the mountain/snowflake
marking
.
on the tire side wall.
These tires meet specific snow traction
performance requirements of the Rub-
ber Manufacturers Association (RMA)
and the Rubber Association of Canada
(RAC) and have been designed specifi-
cally for use in snow conditions. Use of
winter tires is the only way to achieve
the maximum effectiveness of the ABS,
BAS, ASR and ESP
® in winter operation.

Mechanical elements and the lubricants
used for them must be carefully
matched.
For this reason, only brands tested and
approved by the manufacturer should be
used. Please contact your Sprinter Deal-
er to obtain the necessary information.
No lubricant additives should be used.
The use of such additives could affect
your warranty rights. Information is
available from any authorized Sprinter
Dealer.For specifications of engine oils, coolant
and brake fluid, see "Service products
and capacities" (
\2
page 604) and con-
tact your authorized Sprinter Dealer.
Observe the information on spare parts
in the “Technical data” section
(
\2
page 600).
Warning (Continued)

The manufacturer recommends that you
use an authorized Sprinter Dealer for this
purpose. In particular, work relevant to
safety or on safety-related systems must
be carried out at an authorized Sprinter
Dealer.

439 Practical hints
What to do if ...
5
The coolant temperature gauge is above
250°F (+120°C).
The coolant is too hot and the engine is not be-
ing sufficiently cooled.
\1Park your vehicle in a safe location as
quickly as possible and let the engine
continue to run at idle speed for about
1 to 2 minutes before switching it off.
This allows the coolant temperature to
return to normal again.
If the coolant temperature is still too high:
\1Switch off the engine and let it as well
as the coolant cool down.
\1Check the coolant level and observe the
warning notes as you do so
(\2page 329).
\1Add coolant as necessary.
