The red coolant warning lamp
lights up while the engine is run-
ning.
The coolant temperature is too high.
\1Do not drive any further.
\1Consult an authorized Sprinter Dealer.
If the vehicle is switched off after being
subjected to extreme loads (for example
driving in mountainous terrain, trailer
towing, etc.), the coolant warning lamp
may light up when the ignition is switched
on or the engine is restarted. Run the en-
gine for approximately 1 minute at idling
speed.
Consult an authorized Sprinter Dealer if
the coolant warning lamp remains lit.

Warning!
G
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or the tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or the tire inflation pressure label,
you should determine the proper tire infla-
tion pressure for those tires).
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly underinflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significant-
ly underinflated tire causes the tire to over-
heat and can lead to tire failure.
Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping ability. Please
note that the TPMS is not a substitute for
proper tire maintenance, and it is the driv-
er’s responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.
USA only:
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately 1 minute
and then remain continuously illuminated.
This sequence will continue upon subse-
quent vehicle start-ups as long as the mal-
function exists. When the malfunction
indicator is illuminated, the system may not
be able to detect or signal low tire pressure
as intended.
TPMS malfunctions may occur for a variety
of reasons, including the installation of in-
compatible replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your vehicle
to ensure that the replacement or alternate
tires and wheels allow the TPMS to continue
to function properly.

\3 Fuel systemOn vehicles with a diesel engine, it is nec-
essary to drain the fuel filter if the/ in-
dicator lamp lights up.
To this end, have the fuel filter with water
separator drained at an authorized Sprint-
er Dealer which has the necessary special-
ist knowledge and tools to carry out the
work required.The fuel filter with water separator is in the
engine compartment.

\1Drain the fuel filter again if the/ in-
dicator lamp remains lit.If the fuel tank on a vehicle with diesel en-
gine has been run dry, there is a possibility
that the engine may not start immediately
after refueling because air may remain in
the fuel system.
After refueling:
\1Switch on the ignition for approximate-
ly 10 seconds.
\1Start the engine repeatedly for no more
than 60 seconds until it runs smoothly.If the engine does not start:
\1Wait approximately 2 minutes.
\1Then start the engine repeatedly again
for no more than 60 seconds until it
runs smoothly.
If this attempt also fails, do not continue to
start the engine. Consult an authorized
Sprinter Dealer.Environmental note
H
Have the drained liquid disposed of at an
authorized Sprinter Dealer.!
CAUTION
If the / indicator lamp remains lit
even after draining for the second time,
have the cause checked immediately at
an authorized Sprinter Dealer.
