You can set a variable or permanent limit
speed:
R Variable for speed limits, e.g. in built-up
areas
R Permanent for long-term speed restric-
tions, e.g. for driving on winter tyres
( Y page 151 ) G
Risk of accident
Speedtronic is only an aid designed to
assist driving. You are responsible for the
vehicle's speed and for braking in goo d
time.
i The speed indicated in the speedometer
may differ slightly from the limit speed
stored.
Variable Speedtronic You can operate cruise control* and variable
Speedtronic with the cruise control lever.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:
R
LIM indicator lamp off:
Cruise control* is selected

You can use the cruise control lever to restrict
the speed to any speed above 30 km/h while
the engine is running . 1

Check whether LIM indicator lamp 2is on.
If it is on, variable Speedtronic is already
selected.
If it is not, press the cruise control lever in
the direction of arrow 5.

Risk of accident
If there is a change of drivers, advise the
new driver of the limit speed stored.
Only use variable Speedtronic if you are
sure that you will not have to accelerate
suddenly to a speed above that stored as
the limit speed, otherwise you could cause
an accident.
You can only exceed the limit speed store d
if you deactivate variable Speedtronic :
R using the cruise control leve r
R if you depress the accelerator pedal
beyond the pressure point (kickdown )
It is not possible to deactivate variable
Speedtronic by braking. Controls

the speed to any speed above 30 km/h whil e
the engine is running .
X Press the cruise control lever briefly to the
pressure point, either upwards 1or down-
wards 4.
The current speed is stored. For five sec-
onds, the multi-function display shows the
stored speed, e.g. Limit 100 km/h.
Vehicles with the 4-button multi-function
steering wheel: the stored speed is perma-
nently displayed in the status indicator, e.g.
LIM 100 km/h.
Vehicles with a 12-button luxury multi-
function steering wheel*: the segments
from the start of the scale up to the stored
speed light up in the speedometer.

The most important part of the ADVANCE D
AGILITY package with sports mode is the
adjustable suspension system. This automat-
ically controls and adapts the suspension to
the respective driving situation.
The calibration of the suspension depends
on:
R your driving style
R the road surface conditions
R your individual selection; see also the fol-
lowing description
If your vehicle is equipped with automati c
transmission*, the ADVANCED AGILITY pack-
age with sports mode also includes steering-
wheel gearshift paddles* with a manua l
gearshift program* (Y page 121). 1

0
General notes Thermatic is only operational when the
engine is running. Optimum operation is only
achieved when you drive with the side win-
dows and sliding/tilting sunroof*/panorama
sliding sunroof* closed .
You can allow the air-conditioning system to
adjust automatically or you can adjust it man-
ually.
In automatic mode, Thermatic cools or heats
the vehicle interior according to:
R The selected temperature
R The outside temperature
R The intensity of the sunlight
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the sum-
mer opening feature (Y page 111). This
helps you to achieve the desired interior
temperature more quickly.
The integrated filter filters out most particles
of dust and completely filters out pollen.
i A clogged filter reduces the amount of ai r
supplied to the vehicle interior. For this rea-
son, you should always observe the interval
for replacing the filter, which is specified in
the Service Booklet. As it depends on envi- ronmental conditions, e.g. heavy air pollu-
tion, the interval may be slightly shorter
than stated in the Service Booklet. G
Risk of accident
Follow the settings recommended on the
following pages for heating or cooling. The
windows could otherwise mist up. This may
prevent you from observing the traffic con-
ditions, thereby causing an accident. Activating/deactivating Thermati
c
Thermatic is only operational when the
engine is running.

Select this setting when you drive with the
side windows or the sliding/tilting sun-
roof*/panorama sliding sunroof* open, for
example. When Thermatic is deactivated,
the air supply and air circulation are also
switched off. Only select this setting briefl y
when the side windows and the sliding/
tilting sunroof*/panorama sliding sun-
roof* are closed, otherwise the windows
may mist up. Controlling the air conditioning auto-
matically
i If you have set the air-conditioning sys-
tem to automatic, you only need to set the
temperature. In automatic mode, the air-
flow and air distribution do not need to be
adjusted. The cooling with dehumidifica-
tion function is switched on in automatic
mode. If necessary, cooling with dehumid-
ification can be deactivated.

It is possible to make use of the residual heat
of the engine to continue heating the station-
ary vehicle for up to 30 minutes after the
engine has been switched off. The heating
time depends on the coolant temperature and
on the interior temperature that has been set.
i If you activate residual heat at high tem-
peratures, only the ventilation is activated.
i The blower will run at a low speed regard-
less of the airflow setting.

Risk of accident
If you deactivate the cooling function with
air dehumidification, the vehicle will not be
cooled in warm weather and the air will not
be dehumidified. The windows could mis t
up more quickly. This may prevent you from
observing the traffic conditions, thereby
causing an accident. H
Environmental not
e
The cooling system uses the refrigerant
R134A. This refrigerant does not damage
the earth's ozone layer.
i Condensation may drip from the under-
side of the vehicle when Thermatic is in
cooling mode.
Cooling with dehumidification is operational
when the engine is running, and cools accord -
ing to the interior temperature selected. The
air inside the vehicle is also dried, thereby
preventing the windows from misting up.

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.
