Protection of the environment
General notes
H
Environmental 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:
R operating condition sofyour vehicle
R your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
R avoid short trips as these increase fuel con-
sumption.
R always make sure that the tire pressures
are correct.
R do not carry any unnecessary weight.
R remove roof racks once you no longer need
them.
R ar egularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R always have service work carried out at a
qualified specialist workshop.
Personal driving style:
R do not depress the accelerator pedal when
startingt he engine.
R do not warm up the engine when the vehicle
is stationary.
R drive carefully and maintain asafe distance
from the vehicle in front.
R avoid frequent, sudden acceleration and
braking. R
change gear in good time and use each gear
only up to 00C3of its maximum engine speed.
R switch off the engine in stationary traffic.
R keep an eye on the vehicle's fuel consump-
tion. Environmental concerns and recom-
mendations
Wherever the operating instructions require
you to dispose of materials, first try to regen-
erate or re-use them. Observe the relevant
environmental rules and regulations when
disposing of materials. In this way you will
help to protect the environment. Genuine Mercedes-Benz parts
H
Environmental note
Daimler AG also suppliesr econditioned major
assemblies and parts which are of the same
quality as new parts. They are covered by the same Limited Warranty entitlements as new
parts.
! Air bags and Emergency Tensioning Devi-
ces, as well as control units and sensors for these restraint systems, may be installed inthe following areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R cockpit
R instrumen tcluster
R center console
Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficienc yofthe restraint sys-
tems.
Have aftermarket accessories installed at a qualified specialist workshop. 18

WARNING
Fuel is poisonous and hazardous to health.
There is arisk of injury.
You must make sure that fuel does not come int oc ontac twith your skin ,eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors .Keep fuel away from children.
If you or others com eintoc ontac twith fuel,
observ ethe following:
R Wash away fuel from skin immediately
using soap and water.
R If fuel comes int ocontac twith your eyes,
immediately rinse the mthoroughly with
clean water. Seek medical assistanc ewith-
out delay.
R If fuel is swallowed, seek medical assis-
tance without delay. Do not induc evomit-
ing.
R Immediately change out of clothing which
has com eintoc ontac twith fuel. G
WARNING
Electrostatic buildup can create spark sand
ignit efuel vapors .There is arisk of fire and
explosion.
Always touc hthe vehicle body befor eopening
the fuel filler flap or touching the fuel pump
nozzle. An yexisting electrostatic buildup is
thereby discharged.
! Do not use diesel to refuel vehicles with a
gasolin eengine. Do not switc honthe igni-
tion if you accidentally refuel with the
wron gfuel. Otherwise, the fuel will enter
the fuel system. Even small amount softhe
wron gfuel could result in damage to the
fuel syste mand the engine. Notify aquali-
fied specialis tworkshop and have the fuel
tan kand fuel lines draine dcompletely. !
Overfilling the fuel tan
kcould damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the paintwork.
! Use
afilter when refuelin gfrom afuel can.
Otherwise, the fuel lines and/or injection
syste mcould be blocked by particles from
the fuel can.
If you overfill the fuel tank, fuel could spray
out when the fuel pump nozzle is removed.
Further information on fuel and on fuel grades can be foun dinthe "Fuel" section
(Y page 282). Refueling

Information on driving
R If the vehicle is heavily loaded, chec kthe
tire pressures and correct them if neces-
sary.
R While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi- cate that the wheels or tires are damaged.If you suspect that atire is defective,
reduce your speed immediately. Stop the
vehicle as soon as possible to chec kthe
wheels and tires for damage. Hidden tire
damage could also be causing the unusual
handling characteristics. If you find no
signs of damage, have the wheels and tires checked at aqualified specialist workshop.
R When parkin gyour vehicle, make sure that
the tires do not get deformed by the curb or
other obstacles. If it is necessary to drive

The Tire and Loading Informatio nplacard is

(Y page 260).
The Tire and Loading Informatio nplacard con-
tains the recommende dtire pressures for
col dtires. The recommende dtire pressures
ar ev alid for the maximum permissibl eload
and up to the maximum permissibl evehicle
speed.
Tire pressure table The tire pressure table is on the insid

The tire pressure table contains the recom-
mended pressures for col dtiresfor various
operating conditions, i.e .differing load and
spee dconditions. Example: tire pressure table with tire dimensions
If at ire size precedes atire pressure, the tire
pressure informatio nfollowing is onl yvalid

cialist workshop. Important notes on tire pressure
G
WARNING
If the tire pressure drops repeatedly,t he
wheel, valve or tire may be damaged. Tire
pressure that is too low may resultina tire
blow-out. There is arisk of an accident.
R Check the tire for foreign objects.
R Check whether the wheelisl osing air or the
valve is leaking.
If you are unabletor ectify the damage, con-
tact aqualifieds pecialist workshop. G
WARNING
If you fit unsuitable accessorie sonto tire
valves ,the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss. Due to their design, retrofitted tire pres- sure monitors keep the tire valve open. This
can also resultint ire pressure loss. There is a
risk of an accident.
Only screw the standard valve cap or other
valve caps approved by Mercedes-Benz for
yourv ehicle onto the tire valve.
Use asuitable pressure gauge to check the
tire pressure. The outer appearance of atire
does not permit any reliable conclusion about the tire pressure. On vehicle sequippedw ith
the electronic tire pressure monitor, the tire
pressure can be checked in 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 shouldo nly correct tire pres-
sures when the tires are cold. The tires are cold:
R if the vehicle has been parked without
direct sunlight on the tires for at least three
hours and
R if the vehicle has not been driven further
than 1mile (1.6 km)
The tire temperature changes depending on
the outsid etemperature ,the vehicle speed
and the tire load. If the tire temperature
changes by 18 ‡(10 †), the tire pressure
changes by approximately 10 kPa (0.1 bar/
1.5 psi).T ake this into account when check-
ing 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, the result- ing valuew illbeh igherthan if the tires were
cold. This is normal. Do not reduce the tire
pressure to the values pecified for cold tires.
The tire pressure would otherwis ebetoo low.
Observe the recommended tire pressures for
cold tires:

WARNING
Tires with pressure that is too low can over-
heat and burst as aconsequence. In addition,
they also suffer from excessive and/or irreg-
ularw ear, which can severel yimpair the brak-
ing propertie sand the driving characteristics.
There is arisk of an accident.
Avoid tire pressures that are too low in all the
tires, including the spare wheel.

WARNING
Tires with excessively high pressure can burst
because they are damage dmoree asily by
