Protection of the environment
17Protection of the environment
H
Environmental not
e
DaimlerChrysler's declared policy is one of
integrated environmental protection.
The objectives are for the natural resource s
which form the basis of our existence on
this planet to be used sparingly and in a
manner which takes the requirements of
both nature and humanity into account.
You too can help to protect the environ-
ment by operating your vehicle in an envi-
ronmentally-responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tyre wear depend
on the following factors:
R Operating conditions of your vehicle
R Your personal driving style
You can influence both factors.
You should bear the following in mind:
Operating condition s
R Avoid short trips as these increase fuel
consumption.
R Make sure that the tyre pressures are
always correct.
R Do not carry any unnecessary weight. R
Keep an eye on the vehicle's fuel con-
sumption.
R Remove roof racks once you no longer
need them.
R A regularly serviced vehicle will contrib-
ute to environmental protection. Yo u
should therefore adhere to the service
intervals.
R Always have maintenance work carrie d
out at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
Personal driving style
R Do not depress the accelerator peda l
when starting the engine.
R Do not warm up the engine with the vehi-
cle stationary.
R Drive carefully and maintain a safe dis-
tance from the vehicle in front.
R Avoid frequent, sudden acceleration.
R Change gear in good time and use eac h
gear only up to 2
/ 3of its maximum engine
speed.
R Switch off the engine in stationary traffic. Returning used vehicle
s
Mercedes-Benz will take back your
Mercedes-Benz to dispose of it in an environ-
mentally-responsible manner, in accordance
with the European Union (EU) End of Life
Vehicles Directive.
The End of Life Vehicles Directive applies to
vehicles of up to 3.5 t gross vehicle weight, in
accordance with national regulations. For
several years, Mercedes-Benz has been
meeting all the legal requirements for a
design which allows for recycling and re-use.
There is a network of return points and dis-
assembly plants which can recycle your vehi-
cle in an environmentally-responsible man-
ner. The options for recycling vehicles and
parts are constantly being developed and
improved. This means that your Mercedes-
Benz will also continue to meet even the
increased recycling quotas in the future in
good time. You can obtain further information
from your national Mercedes-Benz homepage
or your national hotline number. Introduction

Refuelling
20
4 The first 1,500 km
If you treat the engine with sufficient car e
from the very start, it will reward you with
excellent performance for a very long period
afterwards .
R You should therefore drive at varying road
and engine speeds for the first 1,500 km.
R Avoid heavy loads, e.g. driving at full throt-
tle, during this time. Do not exceed 2
/ 3 of
the maximum permissible engine speed for
each gear.
R Change gear in good time.
R Do not shift down a gear manually in order
to brake.
Vehicles with automatic transmission* :
R Try to avoid depressing the accelerator
pedal beyond the pressure point (kick -
down).
R Only use ranges 3,2 or 1for slow driving,
e.g. in mountainous terrain. Refuellin

Risk of explosion
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Switch off the engine before refuelling. G
Risk of injury
Avoid any contact with fuels.
You can damage your health if your skin
comes into direct contact with fuel or if yo u
inhale the vapour. G
Risk of fire
Do not use petrol to refuel vehicles with a
diesel engine. Never mix diesel with petrol.
This would damage the fuel system and
engine and could result in a vehicle fire.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Never mix
diesel with petrol. Even small amounts of
the wrong fuel will damage the injection
system. Damage resulting from adding the
wrong fuel is not covered by the warranty. !
Do not start the engine if you accidentally
refuelled with the wrong fuel. Otherwise
you risk engine damage. Have the fuel sys-
tem emptied completely.
When you open or close the vehicle with the
key or KEYLESS GO*, the fuel filler flap is
automatically unlocked or locked.
The fuel filler flap is to the rear on the right . 1

3 depth and the condition of the tread
across the entire width of all tyres. If nec
-
essary, turn the steering wheel so that
you can see the tyre tread more easily.
You could otherwise lose control of the
vehicle and cause an accident due to the
reduced grip of the tyres on the road. Tyre pressures
G
Risk of accident
Tyre pressure that is either too high or too
low has a negative effect on the vehicle’ s
active safety, which could lead you to caus e
an accident. You should therefore regularly
check the pressure of all your tyres (includ -
ing the spare tyre*), particularly prior to
long trips, and correct the pressure as nec -
essary.
To test tyre pressure, use a suitable pressure
gauge. The outer appearance of a tyre does
not permit any reliable conclusion about the
tyre pressure.
If the vehicle is to be heavily laden or driven
at high speeds, the tyre pressure must be
adapted according to the specifications given
in the fuel filler flap (Y page 204). Use the highest specified tyre pressure for
the spare wheel*
. G
Risk of accident
Should the tyre pressure drop repeatedly:
R Check the tyre for foreign bodies.
R Check whether the wheel is losing air or
the valve is leaking .
Tyre pressure that is too low has a negative
effect on the vehicle’s active safety, which
could lead to your causing an accident .
Tyre pressure changes by approximately
0.1 bar for every 10 °C change in ambient
temperature.
If you measure the tyre pressure in enclosed
spaces where the temperature differs from
the outside temperature, you will have to cor-
rect the measured value accordingly.
When the vehicle is driven, the tyre tempera-
ture, and with it the tyre pressure, will
increase depending on the road speed and
the load on the tyres.
Therefore, you should only correct tyre pres-
sures when the tyres are cold.
The pressure of warm tyres should only be
corrected if it is too low for the current oper-
ating conditions. You will find a table of tyre pressures for var-
ious operating conditions on the inside of
your vehicle's fuel filler flap.
Driving with tyre pressure that is too high or
too low can:
R
shorten the service life of the tyres
R cause increased tyre damag e
R have a negative effect on handling charac-
teristics (e.g. by causing aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics .
You can, however, also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle.
Also check the tyre pressure of the spare
wheel* . H
Environmental not
e
Check the tyre pressure regularly, and at
least every 14 days. Operation

4 Tyre pressure loss warning system
G
Risk of accident
The tyre pressure loss warning system*
does not warn you of an incorrectly set tyre
pressure. The table on the inside of the fue l
filler flap will help you decide whether the
tyre pressures should be corrected.
The tyre pressure loss warning system*
does not replace the need to regularly
check your vehicle's tyre pressures, since
an even loss of pressure on several tyres at
the same time cannot be detected by the
tyre pressure loss warning system*.
The tyre pressure loss warning system* is
not able to warn you of a sudden loss of
pressure, e.g. following penetration by a
foreign object.
In the event of a sudden loss of pressure,
bring the vehicle to a halt by braking care-
fully. Do not make any sudden steering
movements when doing so.
While the vehicle is in motion, the tyre pres-
sure loss warning system* monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in a tyre. If the spee d
of rotation of a wheel changes as a result of a loss of pressure, a corresponding warning
message will appear in the multi-function dis-
play.
The function of the tyre pressure loss warning
system* is limited or delayed if:
R
snow chains are fitted to your vehicle's
tyres
R road conditions are wintry
R you are driving on sand or grave l
R you adopt a very sporty driving style (cor -
nering at high speeds or driving with high
rates of acceleration)
R you are towing a very heavy or large trailer
R you are driving with a heavy load (in th e
vehicle or on the roof)
Restarting the tyre pressure loss warn-
ing system* Restart the tyre pressure loss warning sys-
tem* if you have
:
R changed the tyre pressure
R changed the wheels or tyre s
R fitted new wheels or tyres
X Before restarting, consult the table of tyre
pressures on the inside of the fuel filler fla pto ensure that the tyre pressure in all fou
r
tyres is set correctly for the operating con-
ditions concerned .
X Also observe the notes in the section on
tyre pressures (Y page 213). G
Risk of accident
The tyre pressure loss warning system* can
only give reliable warnings if you have set
the correct tyre pressure.
If an incorrect tyre pressure is set, thes e
incorrect values will be monitored.
A tyre with insufficient pressure results in
an instability of the vehicle when driving,
thus increasing the risk of an accident .
Configuring with the multi-function steer-
ing wheel
X Make sure that the key is in position 2in
the ignition lock .
X Press èto select Tyre pressure
menu: R.
X Press the íbutton.
