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 recognizet he 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 aqualified
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 ahealth 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 components ystem failures may
also result. There is arisk 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 compartmentisn ot
fully separated from the driver's cab.
Partition with door/window: always keep the
door/window in the partition closed during
transport.
Examples of substances that are hazardous to
health and/or react aggressively:
RSolvents
RFuel
ROil and grease
RCleaning agents
RAcids
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 amanner
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 conditionsofy our vehicle
Ryour personal driving style
You can influence both factors. You should
bear the following in mind:

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print.Country-specific variation sare possi-

Engine compartment
Hood
Important safetyn otes
GWARNING
If the hood is unlatched, it may open up when the vehicle is in motion and block your view.
There is arisk of an accident.
Never unlatc hthe hood while driving. Before
every trip, ensure that the hood is locked.
GWARNING
Openin gthe hood when the engin eisover-
heated or when ther eisafire in the engine
compartmen tcould expose you to hot gases
or other servicep roducts. There isarisk of
injury.
Let an overheated engin ecool down before
openin gthe hood. If ther eisafire in the
engin ecompartment, keep the hood closed
and contact the fire department.
GWARNING
The engin ecompartmen tcontains moving
components. Certain components, such as
the radiator fan, may continue to run or start
again suddenly when the ignition is off. There is ar isk of injury.
If you need to do any work inside the engine
compartment:
Rswitc hoff the ignition
Rneve rreach int othe area where ther eisa
risk of danger from movingc omponents,
such as the fan rotation area
Rremovej ewelry and watches
Rkeep items of clothing and hair, for exam-
ple, away from movingp arts
GWARNING
The ignition system operate swithahigh volt-
age. If you touc hthe live components, you
could receiv eanelectric shock.T here is an
increased risk of injury.
Never touc hcomponents of the ignition sys-
tem if:
Rthe engin eisrunning or being started
Rthe key is in radio position or drive position
in the ignition lock
The live components of the ignition system are,
for example:
Rignition coils
Rspark plug connectors
Rdiagnostic sockets
GWARNING
Certain components in the engin ecompart-
ment ,such as the engine, radiator and parts
of the exhaust system ,can becomev ery hot.
Working in the engin ecompartmen tposes a
risk of injury.
Where possible, let the engin ecool down and
touc honly the components described in the
following.
If you have to carry out work in the engin ecom-
partment ,only touc hthe following components:

Let an overheated engine cool down before
opening the hood. If there is afire in the
engine compartment, keep the hood closed
and contact the fire department.
GWARNING
Certain components in the engine compart-
ment,s uch as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
!Do not use your hands to push the hood
down. You could damage it otherwise.
XHold support strut ?and lift the hood
slightly.
XGuide support strut ?towards retainer =
and apply slight pressure to make it engage.
XLower the hood and allow it to fall with
momentum from aheight of approximately
1ft( 30 cm).
The hood locks audibly.
XCheck that the hood is correctly locked.
If the hood can be raised slightly, it is not
properly engaged. If the hood is not correctly
engaged, open the hood again. Let the hood
fall with alittle more momentum.
Overview of the engine compartment

Engin eoil filler neck cap (Ypage 242)
;Brake fluid reservoir cap (Ypage 245)
=Coolant expansion tank cap (Ypage 244)
?Washer fluid reservoir cap (Ypage 246)
Regularly check the fluid level and the assembly
for leaks. If you detect fluid loss, e.g. oil flecks on the vehicle parking space, consult aqualified
specialist workshop immediately.
Engine oil
General notes
!Engin eoil gets dirty in the course of opera-
tion and its quality and volume are gradually
diminished. Regularly check the oil level, and top up or have it replaced as needed.
Observe the information on approved engine
oils and oil consumption under "Service prod-
ucts and capacities" (
Ypage 298).
You can check the oil level in the engine:
Rwith the oil dipstick
Checking the oil level using the oil dip-
stick

Make sure that engine oil is not spilled nex tto
the filler neck .Let the engine cool down and
thoroughly clean the engine oil off the com-
ponents before starting the engine.
HEnvironmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful to
the environment.
!Do not add too much oil. adding too much
engine oil can result in damage to the engine
or to the catalytic converter. Have excess
