Proper use
Observe the following information when oper-
ating your vehicle:
Rthe safety notes in these operating instruc-
tions
Rthe technical data in these Operating Instruc-
tions
Rtraffic laws and regulations
Rmotor vehicle laws and safety standards
There are various warning stickers affixed to the
vehicle. If you remove warning stickers, you and
others may fail to recognize the dangers. Leave
the warning stickers in their original position.
GWARNING
Modifications to electronic components, their software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
The general operating permit for your vehicle
could be rendered invalid if you carry out mod-
ifications to electronic components, their soft-
ware as well as wiring.
GWARNING
Gases and fluids from substances that con-
stitute a health hazard or react aggressively
can escape even from securely closed con-
tainers. When transporting such substances
in the vehicle interior, your ability to concen-
trate or your health could be affected during
the journey. Malfunctions, short circuits or
electrical component system failures may
also result. There is a risk of an accident and
fire.
Do not store or transport any substances in
the vehicle interior which are hazardous to
health or react aggressively.
These instructions must also be observed for
vehicles where the cargo compartment is not
fully separated from the driver's cab.
Partition with door/window: always keep the
door/window in the partition closed during
transport.

Protection of the environment
Economic and environmentally aware
driving
HEnvironmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected
by these factors:
Roperating conditions of your vehicle
Ryour personal driving style
You can influence both factors. You should
bear the following in mind:
Introduction25
Z
Rswitch off the electrical system using the bat-
tery main switch (Ypage 118) and
Rdisconnect the vehicle's auxiliary battery
Otherwise, you need to check the battery's con- dition of charge every 3 weeks, since standby
power consumption can drain the battery. If the
battery voltage is lower than 12.2 V, the battery
must be charged. Otherwise, the battery may be
damaged by exhaustive discharging.
Be sure to observe the notes on disconnecting
and charging the batteries under "Battery"
(
Ypage 228). You can obtain information about
trickle chargers from a qualified specialist work-
shop.
If you leave the vehicle parked for longer than
6 weeks, the vehicle may suffer damage as a
result of lack of use. In this event, consult a
qualified specialist workshop.
Driving tips
General notes
Important safety notes
GWARNING
The driver's attention to the road must always be his/her primary focus when driving. For
your safety and the safety of others, we rec-
ommend that you pull over to a safe location
and stop before placing or taking a telephone
call. If you choose to use the telephone while
driving, please use the hands-free device and
only use the telephone when road, weather
and traffic conditions permit.
Some jurisdictions prohibit the driver from
using a mobile phone while driving a vehicle.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle covers
a distance of 44 feet (approximately 14 m)
every second.
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
!Always observe the ground clearance of the
vehicle and avoid obstacles. On vehicles with a step, ground clearance is further restricted.
Obstacles can damage the vehicle.
If you must drive over obstacles, drive espe-
cially slowly and carefully. If necessary, have
another person direct you.
Drive sensibly – save fuel
In order to save fuel, observe the following tips:
XThe tires should always be inflated to the rec-
ommended tire pressure.
XRemove unnecessary loads.
XRemove roof carriers when they are not nee-
ded.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenance work carried out as
indicated by the service intervals in the Main-
tenance Booklet or by the service interval dis-
play.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in moun-
tainous terrain.
Overrun cutoff
If you are in overrun mode and take your foot off
the accelerator pedal, the fuel supply is cut off
when the engine speed is out of the idle speed
control range.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent are greatly increased when you drink or
take drugs and drive.

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 cir-
cumstances 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 pressures for
cold tires:

Underinflated or overinflated tires
Underinflated tires:
GWARNING
Tires with pressure that is too low can over-
heat and burst as a consequence. In addition, they also suffer from excessive and/or irreg-
ular wear, which can severely impair the brak-
ing properties and the driving characteristics.
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:
Rfail from being overheated
Radversely affect handling
Rwear excessively and/or unevenly
Rhave an adverse effect on fuel consumption
Overinflated tires
GWARNING
Tires with excessively high pressure can burst
because they are damaged more easily 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.

To prevent operating problems, diesel with bet-
ter flow qualities is available during the winter
months. You can obtain information at the gas
station or from your fuel supplier.
Your vehicle is equipped with a fuel preheating
system. This improves the flow properties of the
diesel by approximately 14.5 ‡ (8 †). ULTRA-
LOW SULFUR DIESEL can be used without risk
of malfunction down to an outside temperature
of approximately 14 ‡ (Ò10 †).
Fuel additives
!Do not add gasoline or kerosene to diesel
fuel to improve its flow characteristics. Gas-
oline or kerosene impairs the lubricating
properties of the diesel fuel. This can result in
damage to the fuel injection system, for
example.
B20 fuels with bio-diesel content
!Continuous use of fuels with bio-diesel con-
tent over 5% (B20 fuels) can lead to fuel filter
clogging. Deposits may also form on the fuel
injector. This may reduce the engine output.
Unburned fuel can get into the oil pan. This
causes the engine oil level to rise. This can
cause engine mechanical damage.
To avoid damages and performance degrada-
tion, observe the following points:
RFill up with fuels with bio-diesel content of
5% (ULSD) or less, whenever possible.
RRegularly monitor your engine oil level if
you use B20 fuels on a regular basis.
RStrictly follow the oil change intervals quo-
ted in the instrument cluster and within
your maintenance booklet.
RUse only engine oils and filters approved for
use in your vehicle.
RIf you do not plan to drive your vehicle for
several weeks, completely fill the fuel tank
in advance with ULSD fuel.
For more information, consult the gas station
staff. The identification of fuels with bio-diesel
content (ULSD or B20) must be clear. If the
marking does not make this clear, do not refuel
from that pump.
Do not refuel with any fuels that have not been
approved for your vehicle.

Ypage 127).
Information on fuel consumption
HEnvironmental note
CO
2(carbon dioxide) is the gas which scien-
tists believe to be principally responsible for
global warming (the greenhouse effect). Your
vehicle's CO
2emissions are directly related to
fuel consumption and therefore depend on:
Refficient use of the fuel by the engine
Rdriving style
Rother non-technical factors, such as envi-
ronmental influences, road conditions or
traffic flow
You can minimize your vehicle's CO
2emis-
sions by driving carefully and having it serv-
iced regularly.
Fuel consumption depends on:
Rthe vehicle version
Rthe style of driving
Rthe operating conditions
Rthe type or quality of the fuel used
The vehicle will use more fuel than usual in the
following situations:
Rat very low outside temperatures
Rin city traffic
Rduring short journeys
Ron mountainous terrain
Rwhen towing a trailer
To keep fuel consumption low, observe the
advice in the "Protection of the environment"
section (
Ypage 25).
The following components of the different vehi-
cle versions influence fuel consumption:
Rtire sizes, tire tread, tire pressure, tire condi-
tion
Rbody
Rtransmission ratios for the drive assemblies
Radditional equipment (e.g. air-conditioning
system, auxiliary heating system)
For these reasons, the actual consumption fig-
ures for your vehicle may deviate from the con-
sumption figures determined according to EU
Directive 80/1268/EE C.
Data concerning fuel consumption are recorded in the on-board computer; use the steering

Diesel Exhaust Fluid (DEF)
General notes
When opening the DEF tank filler cap at high
outside temperatures, ammonia vapors may
escape.
Ammonia vapors have a pungent smell and pri-
marily cause irritation of the:
Rskin
Rmucous membranes
Reyes
You may experience a burning sensation in your
eyes, nose and throat, as well as coughing and
watering of the eyes.
Do not inhale ammonia vapors. Avoid contact
with DEF.
Do not allow DEF to come into direct contact
with your skin; it is hazardous to your health.
Rinse any affected areas off with plenty of clean water. Consult a doctor if necessary.
If DEF heats up, e.g. in direct sunlight, in the DEF
supply reservoir for some time to over 122 ‡
(50 †) , ammonia vapor will develop.
To conform to emission regulations, you must
operate the vehicle with DEF and refill the supply
regularly. The engine management recognizes
attempts to operate the vehicle without DEF,
with thinned DEF or with another reducing
agent. After previous warning messages, the
engine management then prevents a further
engine start.
When the number of remaining engine starts is 0
the engine management prevents the vehicle
from being driven at a speed exceeding 5 mph
(8 km/h). The multifunction display shows the
Idle Mode
message.
DEF consumption
DEF consumption depends on operational and
driving conditions and it is not necessary to wait
until the next scheduled service to replenish the
fluid. Therefore, refill the DEF supply tank regu-
larly during vehicle operation or, at the latest,
after receiving the first warning message via the
on-board computer.
Low ambient temperatures
DEF freezes at a temperature of approximately
12‡(Ò11 †). The vehicle is equipped with a DEF
preheating system at the factory. Winter oper-
ation is therefore also guaranteed at tempera-
tures under 12 ‡ (Ò11 †).
iIf you add DEF at temperatures below 12 ‡
(Ò11 †) it is possible that the level is not
shown correctly due to the frozen DEF.
Drive for at least 20 minutes (heating phase in
the fuel tank activated) and then stop the
vehicle for at least 30 seconds. The level is
then shown correctly.
Additives
!Do not mix DEF with any additives and do
not dilute DEF with tap water. Otherwise, the
exhaust gas aftertreatment may be damaged.
Observe the MB Specifications for Service
Products, Sheet No. 352.0.
Damage that arises through the use of addi-
tives or tap water will invalidate the New Vehi-
cle Limited Warranty.
Storage
!Containers made of aluminum, copper, cop-
per alloys as well as unalloyed or galvanized
steel are not suitable for storing DEF. If stored
in these types of containers, DEF could cause
constituents of these metals to dissolve and
cause irreparable damage to the exhaust gas
aftertrea tment.
Da
mage caused by such impurities in the DEF
will invalidate the New Vehicle Limited War-
ranty.
Only store DEF in containers made of high-alloy
Cr‑ Ni steel or Mo ‑Cr‑Ni steel in accordance with
DIN EN 10 088 ‑1/2/3 or plastic containers
made of polypropylene or polyethylene.
Purity
!Impurities in DEF (e.g. caused by other ser-
vice products, cleaning agents, dust, etc.)
result in increased emissions, malfunctions,
catalytic converter damage or engine dam-
age.
The purity of DEF is essential to prevent mal-
functions in the exhaust gas aftertreatment.
If DEF is pumped out of the DEF tank, e.g. during
repair work, the same liquid must not be used to
refill the tank. Its purity is no longer guaranteed.
