responsible manner. Comply with the instruc-
tions for use of the care products.
Do not run the engine for longer than neces-
sary when the vehicle is stationary.
Before having maintenance and repairs per-
formed, it is essential to read the materials rela-
ted to the maintenance and repairs:
Rthe applicable sections of the technical doc-
umentation, e.g. the Operator's Manual and
workshop information.
Rregulations such as industrial safety regula-
tions and accident prevention regulations.
While working under the vehicle, you must
secure the vehicle on jack stands with sufficient load capacity.
Never use the jack as a substitute. The vehicle's
jack is intended only to raise the vehicle for a
short time when changing a wheel. It is not
suited for performing maintenance work under
the vehicle.
Please also refer to the notes about qualified
specialist workshops (
Ypage 27).
The scope and regularity of the inspection and
maintenance work primarily depend on the
often diverse operating conditions. Specialist
knowledge beyond the scope of this Operator's
Manual is required when carrying out testing
and maintenance work. This work should only be
carried out by trained staff.
The vehicle Maintenance Booklet describes the scope and frequency of maintenance work and
contains additional notes on the New Vehicle
Limited Warranty and on service products.
Maintenance services must be carried out in
accordance with the provisions and recommen-
dations in the Maintenance Booklet. Not doing
so could void the warranty claim and lead to
refusal of goodwill gestures after the manufac-
turer has submitted a damage report.
iObserve the notes on genuine Sprinter parts
(Ypage 29).
Service interval display

Battery
Important safety notes
Work on the battery, e.g. removing or installing,
requires specialist knowledge and the use of
special tools. Therefore, always have work on
the battery carried out at a qualified specialist
workshop.
GWARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This can
lead to function restrictions applying to
safety-relevant systems, e.g the lighting sys-
tem, the ABS (anti-lock braking system) or the
ESP
®(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example:
Rwhen braking
Rin the event of abrupt steering maneuvers
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar inci-
dent, contact a qualified specialist workshop
immediately. Do not drive any further. You
should have all work involving the battery car- ried out at a qualified specialist workshop.
Further information can be found under "ABS"
(
Ypage 53) and under "ESP®" (Ypage 55).
GWARNING
Electrostatic build-up can lead to the creation of sparks, which could ignite the highly explo-
sive gases of a battery. There is a risk of an
explosion.
Before handling the battery, touch the vehicle
body to remove any existing electrostatic
build-up.
The flammable gas mix is produced when the
battery is charged or when the vehicle is jump-
started.
Always make sure that neither you nor the bat-
tery are electro statically charged. Electrostatic
charging results, for example, from:
Rwearing synthetic clothing
Rfriction between clothing and the seat
Rdragging or pushing the battery across carpet
flooring or any other synthetic materials
Rrubbing the battery with cloths or towels.
Comply with the following safety precautions
and take protective measures when handling
batteries.
Risk of explosion. Explosive oxyhy-
drogen is produced when batteries
are being charged. Only charge bat-
teries in well-ventilated areas.
Fire, open flames and smoking are
therefore prohibited when working
on the battery. Avoid creating
sparks.
Battery acid is caustic. Avoid con-
tact with the skin, eyes or clothing.
Wear acid-proof protective gloves. If
skin or clothes are splashed with
acid, neutralize the splashes imme-
diately with soapy water or an acid
neutralizer, and then clean the affec-
ted areas with water. Consult a doc- tor if necessary.
Wear eye protection. When mixing
water and acid, the liquid can splash
into your eyes. Rinse acid splashes
to the eyes immediately with clean

flated tire causes the tire to overheat and canlead to tire failure. Underinflation also
reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stop-
ping 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 if the
system is not operating properly. The TPMS
malfunction indicator is combined with the
low tire pressure telltale. When the system
detects a malfunction, the warning lamp will
flash for approximately a minute and then
remain continuously illuminated. This
sequence will be repeated every time the vehi-
cle is started as long as the malfunction
exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons,
including the mounting of incompatible
replacement or alternate tires or wheels on
the vehicle that prevent the TPMS from func-
tioning properly. Always check the TPMS mal-
function 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 prop-
erly.
Vehicles with a tire pressure monitor are equip-
ped with sensors in the wheels that monitor the
tire pressure of all four tires. The tire pressure
monitor monitors the pressure in all four tires;
you set this pressure when you activate the tire pressure monitor. The tire pressure monitor
warns you when the pressure drops in one or
more of the ti
res. The tire pressure monitor only
functions if the corresponding sensors are
installed on all wheels. You should always adjust the tire pressure
according to the vehicle load. Restart the tire
pressure monitor if you change the tire pres-
sure.
The tire pressure monitor does not warn you if a
tire pressure is incorrect. Observe the notes on the recommended tire pressure (
Ypage 246).
The tire pressure monitor is not able to warn you
of a sudden loss of pressure, e.g. following pen- etration by a foreign object. In this event, brake
the vehicle until it comes to a standstill. Do not
carry out any sudden steering maneuvers.
The tire pressure monitor has a yellow h
warning lamp in the instrument cluster for indi-
cating pressure loss/malfunctions (USA) or
pressure loss (Canada). Depending on how the
warning lamp flashes or lights up, an underin-
flated tire or a malfunction in the tire pressure
monitor is displayed:
Rif the h warning lamp is lit continuously,
the tire pressure on one or more tires is sig-
nificantly too low. The tire pressure monitor is
not malfunctioning.
RUSA only: if the hwarning lamp flashes for
60 seconds and then remains lit constantly,
the tire pressure monitor is malfunctioning.
Only vehicles with steering wheel buttons: the
on-board computer displays information on tire
pressure. After a few minutes of driving, the cur-
rent tire pressure of each tire is shown in the on-
board computer.
USA only: if the tire pressure monitor is mal-
functioning, it may be more than 10 minutes
before the malfunction is shown. The htire
pressure warning lamp flashes for 60 seconds
and then remains lit. When the malfunction has been rectified, the htire pressure warning
lamp goes ou
t after a few minutes of driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at a gas station with a pressure gage. The
tire pressures shown by the on-board computer
refer to those measured at sea level. At high
altitudes, the tire pressure values indicated by a pressure gage are higher than those shown by
the on-board computer. In this case, do not
reduce the tire pressures.
If radio transmitting equipment (e.g. wireless
headphones, two-way radios) is operated inside
the vehicle or in the vicinity of the vehicle, this
can interfere with the operation of the tire pres-
sure monitor.

Tire pressure loss warning system
Vehicles with steering wheel buttons
If the tire pressure monitor detects a pressure
loss in one or more tires, the on-board computer
displays the yellow Tire
pres.Adjustpres.warning message. The htire pressure loss
warning lamp in the instrument cluster
(
Ypage 197) flashes for about 60 seconds and
then remains lit.
The pressure of the affected tire is highlighted in
yellow in the on-board computer (
Ypage 173).
If the tire pressure monitor detects a significant
pressure loss in one or more tires, the on-board
computer displays the red Tire pres.
Warn‐ingTiredefectwarning message. Theh
tire pressure loss warning lamp in the instru-
ment cluster (
Ypage 197) flashes for about 60
seconds and then remains lit. An additional
warning tone sounds. The pressure of the affected tire is highlighted in
yellow in the on-board computer (
Ypage 173).
Restarting the tire pressure monitor
When you restart the tire pressure monitor, the
currently set tire pressures are taken as refer-
ence values for monitoring.
In most cases, the tire pressure monitor detects
the new reference values automatically, e.g.
after you have:
Rchanged the tire pressure
Rchanged wheels or tires
Rinstalled new wheels or tires
However, you can also define reference values
manually as described here.
Before restarting the tire pressure monitor:
