The prescribed service interval is based on
normal vehicle use. Service work will need to
be performed more frequently than prescribed
if the vehicle is operated under more arduous
conditions or with higher loads. Such arduous
conditions include:
R regular city driving with frequent intermedi-
ate stops
R driving predominantly short distances
R frequent operation in mountainous terrain or
on poor road surfaces
R leaving the engine idling for long periods on
a frequent basis
In these or similar operating conditions, have
the air filter, engine oil and oil filter, for exam-
ple, replaced more frequently. Under more
arduous operating conditions, the tires must
be checked more often. Further information
can be obtained at a qualified specialist work-
shop, e.g. an authorized Mercedes-Benz Com-
mercial Van Center.

Important safety notes
Work on the battery, e.g. removing or instal-
ling, requires specialist knowledge and the use
of special tools. Therefore, always have work
on the battery carried out at a qualified spe-
cialist workshop. G
WARNING
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
system, the ABS (anti-lock braking system)
or the ESP ®
(Electronic Stability Program).
The operating safety of your vehicle may be
restricted.
You could lose control of the vehicle, for
example:
R when braking
R in 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
incident, contact a qualified specialist work-
shop immediately. Do not drive any further.
You should have all work involving the bat-
tery carried out at a qualified specialist
workshop.
Further information can be found under "ABS"
(Y page
67) and under "ESP ®
" (Y page 68). G
WARNING
Electrostatic build-up can lead to the crea-
tion of sparks, which could ignite the highly
explosive gases of a battery. There is a risk
of an explosion.
Before handling the battery, touch the vehi-
cle 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. 258

Always make sure that neither you nor the bat-
tery are electro statically charged.
An electrostatic charge can build up in the fol-
lowing situations:
R wearing synthetic clothing
R friction between clothing and the seat
R dragging or pushing the battery across car-
pet flooring or any other synthetic materials
R by rubbing the battery with a cloth 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
batteries 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
affected areas with water. Consult
a doctor 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 water and contact a
doctor immediately.
Keep children at a safe distance.
Children are not able to assess the
dangers posed by batteries and
acid.
When handling batteries, observe
the safety precautions and special
protective measures contained in
this Operator's Manual.
H
Environmental note Batteries contain pollutants.
It is illegal to dispose of
them with the household
rubbish. They must be col-
lected separately and dis-
posed of in an environmen- tally responsible recycling
system. Dispose of batteries in an
environmentally responsible
manner. Take discharged
batteries to a qualified spe-
cialist workshop or to a col-
lection point for used bat-
teries.
Observe the following notes: R have the batteries recharged more fre-
quently in the following situations:
- if you predominantly drive short distan-
ces.
- if you predominantly drive at low outside
temperatures.
- if you leave the vehicle parked for a
lengthy period.
In order for the batteries to achieve their
maximum possible service life, they must
always be sufficiently charged.
R Consult an authorized Mercedes-Benz Com-
mercial Van Center if you wish to leave your
vehicle parked for a long period of time.
R When you park the vehicle, remove the key
if you do not require any electrical consum-
ers. The vehicle will then use very little
energy, thus conserving battery power.
R If your vehicle requires jump-starting, or if
you wish to provide jump-starting assistance
to another vehicle, only use the jump-start-
ing connection point in the engine compart-
ment
(Y page 272).
R Have the battery removed at a qualified spe-
cialist workshop. Installation locations
Your vehicle may be equipped with the follow-
ing three batteries, depending on the equip-
ment level:
R Starter battery in the seat base of the right-
hand front seat

WARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery,
gases can escape from the battery. There is
a risk of an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
If the indicator/warning lamps do not light up
in the instrument cluster when temperatures
are low, it is probably because the discharged
battery has frozen. Should this be the case, do
not jump-start the vehicle or charge the bat-
tery. The service life of a thawed battery may
be shorter. Start-up behavior may deteriorate,
in particular at low temperatures. Have the 262

WARNING
Battery acid is caustic. There is a risk of
injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash away battery acid immedi-
ately with plenty of clean water and seek
medical attention. G
WARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery,
gases can escape from the battery. There is
a risk of an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
! Vehicles with a gasoline engine:
avoid
repeated and lengthy starting attempts. Oth-
erwise, the catalytic converter could be
damaged by non-combusted fuel.
If the indicator and warning lamps in the
instrument cluster do not light up at low tem-
peratures, the discharged battery may have
frozen. In this case you may neither charge the
battery nor jump-start the vehicle. The service
life of a thawed battery may be shorter. Start-
up behavior may deteriorate, in particular at
low temperatures. Have the thawed battery
checked at a qualified specialist workshop.
Do not use a rapid charging device to start the
vehicle. If your vehicle's battery is discharged,
the engine can be jump-started from another
vehicle or from a donor battery using jumper
cables. For this purpose, the vehicle has a
jump-starting connection point in the engine
compartment.
When jump-starting, observe the following
points:
R The battery is not accessible in all vehicles.
If the other vehicle's battery is not accessi-
ble, jump-start the vehicle using a donor
battery or a jump-starting device.
R You may only jump-start the vehicle when
the engine and exhaust system are cold.
R Do not start the engine if the battery is fro-
zen. Let the battery thaw first. R
Jump-starting may only be performed from
batteries with a nominal voltage of 12 V.
R Only use jumper cables that have a suffi-
cient cross-section and insulated terminal
clamps.
R If the battery is fully discharged, attach the
battery of another vehicle for a few minutes
before attempting to start. This charges the
empty battery a little.
R Make sure that the two vehicles do not
touch.
Make sure that:
R The jumper cables are not damaged.
R Bare parts of the terminal clamps do not
come into contact with other metal parts
while the jumper cables are connected to
the battery.
R The jumper cables cannot come into contact
with parts such as the V-belt pulley or the
fan. These parts move when the engine is
started and while it is running.
Jumper cables and further information regard-
ing jump starting can be obtained at any quali-
fied specialist workshop. Before connecting the jumper cables
X Apply the parking brake.
X Shift the transmission to position j.
X Switch off all electrical consumers, e.g.
audio equipment, blower.

Warning
A flat tire severely impairs the driving, steer-
ing and braking characteristics of the vehi-
cle. There is a risk of an accident.
do not drive with a flat tire. Immediately
replace the flat tire with your spare wheel,
or consult a qualified specialist workshop. G
WARNING
If you install wheels and tires with incorrect
dimensions, the service brake or wheel sus-
pension components may be damaged.
There is a risk of an accident.
Always replace wheels and tires with ones
that comply with the specifications of the
original part.
When replacing wheels, pay attention to the:
R Designation

Accessories that are not approved for your
vehicle by Mercedes-Benz or are not being
used correctly can impair operating safety. Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and inquire about the following points:
R
suitability
R legal stipulations
R factory recommendations
Information on the dimensions and types of
wheels and tires for your vehicle can be found
under "Wheel and tire combinations"
( Y page
301).
Information on your vehicle's tire pressures
can be found in the following locations:
R in the Tire and Loading Information placard
on the B-pillar, driver's side
R in the tire pressure table inside the fuel filler
flap ( Y page 282)
R under "Tire pressure tables" (Y page 289)
R under "Tire pressure" (Y page 282)
Modifications to the brake system or wheels
are not permitted. The use of spacers or brake
dust shields is not permitted. This invalidates
the general operating permit for the vehicle.
Further information on wheels and tires can be
obtained at any qualified specialist workshop. Operation
Information for a journey
If the vehicle is heavily laden, check the tire
pressures, and correct them, if necessary
( Y page
282).
While driving, pay attention to vibrations,
noises and unusual handling characteristics,
e.g. pulling to one side. This may indicate that
the wheels or tires are damaged. If you sus-
pect that a tire is defective, reduce your speed
immediately. Stop the vehicle as soon as pos-
sible to check the wheels and tires for dam-
age. Hidden tire damage could also be causing
the unusual handling characteristics. If you
find no signs of damage, have the tires and
wheels checked at a qualified specialist work-
shop.
When parking your vehicle, make sure that the
tires do not get deformed by the curb or other
obstacles. If it is necessary to drive over curbs,
speed humps or similar elevations, try to do so
slowly and not at a sharp angle. Otherwise, the
tires, particularly the sidewalls, can get dam-
aged. 278

Regular wheel and tire checks
G
WARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control
of your vehicle. There is a risk of accident.
Check the tires regularly for signs of dam-
age and replace any damaged tires immedi-
ately.
Check the wheels and tires of your vehicle for
damage regularly, i.e. at least every two
weeks, as well as after driving off-road or on
rough roads. Damaged wheels can cause a
loss of tire pressure. Pay particular attention
to damage such as:
R cuts in the tires
R punctures
R tears in the tires
R bulges on tires
R deformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tire tread across the whole
width of all the tires
(Y page 279). If neces-
sary, turn the front wheels to full lock in order
to inspect the inner side of the tire surface.
All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
install anything onto the valve other than the
standard valve cap or other valve caps
approved for your vehicle by dealers listed on
the inside of the front cover. Do not install any
other valve caps or systems, e.g. tire pressure
monitor systems.
Regularly check the pressure of all the tires,
particularly prior to long trips. Adjust the tire
pressure if necessary (Y page 282).
The service life of tires depends on various
factors, including the following:
R Driving style
R Tire pressure
R Mileage Tire tread
G
WARNING
If there is insufficient tire tread, the tire trac-
tion decreases. The tire tread is no longer
able to dissipate water. This increases the risk of hydroplaning when the road surface
is wet, particularly when the vehicle's speed
is not adapted to the road conditions. There
is a risk of an accident.
When the tire pressure is too high or too
low, tires may wear differently at different
points on the tire tread. Therefore, regularly
check the tire tread depth and the condition
of the tread across the whole width of all
tires.
Minimum tire tread depth on:
R Summer tires: â in (3 mm
)
R M+S tires: ã in (4 mm)
For safety reasons, have the tires replaced
before they reach the legally prescribed min-
imum tire tread depth. Marker : shows the location where the bar
indicator (arrow) for tread wear is integrated
into the tire tread.
Tread wear indicators (TWIs) are required by
law. Six indicators are positioned over the tire
tread. They are visible once the tire tread
depth is approximately á in (1.6 mm
). If this
is the case, the tire is so worn that it must be
replaced. Selecting, mounting and replacing
tires
R Only mount tires and wheels of the same
type and make.
R Only use wheels with tire sizes approved by
Mercedes-Benz.
R Only mount tires of the correct size onto the
wheels. Operation

Important notes on tire pressure
G
WARNING
If the tire pressure drops repeatedly, the
wheel, valve or tire may be damaged. Tire
pressure that is too low may result in a tire
blow-out. There is a risk of an accident. R Check the tire for foreign objects.
R Check whether the wheel is losing air or
the valve is leaking.
If you are unable to rectify the damage, con-
tact a qualified specialist workshop.
Use a suitable pressure gauge to check the
tire pressure. The outer appearance of a tire
does not permit any reliable conclusion about
the tire pressure. On vehicles equipped with
the electronic tire pressure monitor, the tire
pressure can be checked using the on-board
computer.
The tire temperature and pressure increase
when the vehicle is in motion. This is depend-
ent on the driving speed and the load.
Therefore, you should only correct tire pres-
sure when the tires are cold.
The tires are cold: R if the vehicle has been parked for at least
three hours without direct sunlight on the
tires, and
R if the vehicle has not been driven further
than
1 mile (1.6 km)
Tire temperature changes depending on the
ambient temperature, driving speed and tire
load. If the tire temperature changes by 18 ‡
(10 †), the tire pressure changes by approx-
imately 10 kPa (0.1 bar/1.5 psi). Take this into
account when checking the pressure of warm
tires. Only correct the tire pressure if it is too
low for the current operating conditions. If you
check the tire pressure when the tires are
warm, it results in a higher value than when
the tires are cold. This is normal. Do not under
any circumstances release the air in order to
adjust the pressure to the prescribed value for
cold tires. The tire pressure would otherwise
be too low.
Observe the recommended tire pressure for
cold tires on the tire pressure table in the fuel
filler flap. Driving with tire pressure that is too high or
too low can:
R shorten the service life of the tires
R cause increased tire damage
R have a negative effect on handling charac-
teristics and thus the driving safety (e.g.
hydroplaning) Underinflated or overinflated tires
Underinflated tires: G
WARNING
Tires with pressure that is too low can over-
heat and burst as a consequence. In addi-
tion, they also suffer from excessive and/or
irregular wear, which can severely impair the
braking properties and the driving character-
istics. There is a risk of an accident.
Avoid tire pressures that are too low in all
the tires, including the spare wheel.
Underinflated tires can:
R fail from being overheated
R adversely affect handling
R wear excessively and/or unevenly
R have an adverse effect on fuel consumption
Overinflated tires G
WARNING
Tires with excessively high pressure can
burst because they are damaged more eas-
ily by road debris, potholes etc. In addition,
they also suffer from irregular wear, which
can severely impair the braking properties
and the driving characteristics. There is a
risk of an accident.
Avoid tire pressures that are too high in all
the tires, including the spare wheel.
Overinflated tires can:
R increase the braking distance
R adversely affect handling
R wear excessively and/or unevenly
R adversely affect ride comfort
R be more susceptible to damage284

each vehicle and may deviate from the val-
ues in the illustration. Tire valve (snap-in valve)
Important safety notes G
WARNING
Tire valve that are not approved for your
vehicle by the distributor named on the
inside cover page may result in a loss of tire
pressure. This may affect road safety. There
is a risk of an accident.
Only use tire valve that are approved for
your vehicle by the distributor named on the
inside cover page. Always make sure you
have the correct tire valve type for the tires
on your vehicle.
! Do not screw additional weights (check
valves, etc.) onto the tire valves. The elec-
tronic components could thus be damaged.
i For safety reasons, Mercedes-Benz recom-
mends that you only use tire valves that
have been tested for use on your vehicle. Checking the tire pressure manually
In order to determine and adjust the tire pres-
sures, proceed as follows: X Remove the valve cap of the tire you wish to
check.
X Press the tire pressure gauge securely onto
the valve.
X Read the tire pressure and compare it with
the recommended value on the loading
information table or the tire pressure table
( Y page
282).
X If the tire pressure is too low, increase it to
the recommended value.
X If the tire pressure is too high, release air by
pressing down the metal pin in the valve.
Use the tip of a pen, for example. Then,
check the tire pressure again using the tire
pressure gauge.
X Screw the valve cap onto the valve.
X Repeat the steps for the other tires. Tire pressure monitor
General notes In vehicles with a tire pressure monitor sys-
tem, the vehicle's wheels have sensors instal-
led which monitor the tire pressure in all four
tires. The tire pressure monitor warns you if
the pressure drops in one or more of the tires.
The tire pressure monitor only functions if the
corresponding sensors are installed on all
wheels.

and then remains lit. When the malfunction
has been rectified, the h tire pressure
warning lamp goes out 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 gauge.
The tire pressures shown by the on-board
computer refer to those measured at sea level.
At high altitudes, the tire pressure values indi-
cated by a pressure gauge 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 vehi-
cle, this can interfere with the operation of the
tire pressure monitor.
