For coolant specifications, see "Service
products and capacities" (

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.

CAUTION
Brake fluid corrodes paintwork. If
brake fluid comes into contact with
the paintwork, immediately rinse
with water.
If the brake fluid does not reach the
MIN mark, the vehicle’s hydraulic
system could be malfunctioning. Do
not add brake fluid under any cir-
cumstances. This will not solve the
problem.
Do not drive any further.
Have the system checked immediate-
ly at an authorized Sprinter Dealer.
Warning
G
Brake fluid is hazardous to health. Do not
swallow brake fluid. Consult a doctor im-
mediately if any brake fluid is swallowed.Brake fluid must not come into contact
with the skin, eyes or clothing. Wash af-
fected areas with plenty of clean water
and consult a doctor immediately if nec-
essary.You should always wear eye pro-
tection and gloves when you are adding
brake fluid.

Check assemblies regularly for leaks. In
the event of fluid loss (e.g. spots of oil
under the vehicle when it has been
parked), have the cause traced and rec-
tified immediately at an authorized
Sprinter Dealer which has the necessary
specialist knowledge and tools to carry
out the work required.The manufacturer recommends that you
use an authorized Sprinter Dealer for
this purpose. All work relevant to safety
or on safety-related systems must be
carried out at an authorized Sprinter
Dealer.

337 Operation
Battery
4
The batteries must always be sufficiently
charged so that they achieve their in-
tended service life.
Have the battery charge status checked
more frequently if you use the vehicle
mainly for short trips or if you leave it
parked up for a long period.
If you intend to leave your vehicle
parked up for a long period, seek advice
from an authorized Sprinter Dealer and
switch off the electrical system at the
battery isolating switch (
\2
page 338).You will find further information in the
“Practical hints” section (
\2
page 573).
!
CAUTION
Switch off the engine and wait for
approximately 20 seconds before you
loosen or disconnect the terminal
clamps. You could otherwise damage
electrical system components.Care of batteries!
CAUTION
Dirty terminal clamps and battery
surfaces cause leakage current, lead-
ing to battery discharge. Always keep
the terminal clamps and battery sur-
faces clean and dry. Lightly grease
the terminal clamps, particularly the
undersides, with acid-proof grease.
!
CAUTION
Cleaning agents containing fuel can
corrode the battery casing. Only
clean with commercially available
cleaning agents and clean the bat-
tery casing with the cell caps
screwed in.

onset of winter at an authorized Sprinter
Dealer. This service includes the follow-

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

The antifreeze / anti-corrosion con-
centration in the coolant is checked
\4
The addition of a concentrated

fuel for use at low outside temperatures
in the “Technical data” section
(
\2
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
1 or on the tire inflation pres-
sure placard located on the driver’s door
B-pillar, refer to “Tires and wheels” (
\2
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.
Winter tires1. For vehicles with a gross weight capacity less
than 10 000 lbs (4 536 kg) (USA only).

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.
