WARNING
- You should exercise particular care when
driving on difficult road surfaces, and try to
anticipate hazards in advance. Excessive
speed or careless manoeuvres can result in
personal injury or damage to the vehicle.
- Always adjust your speed to suit the terrain
or road surface and weather or traffic condi­

tions.
Drive extra slowly when visibility is
limited by uneven terrain.
- Please note that there can be an increased
tendency for the wheeLs to spin in ESC off-

•} For
the sake of the environment
Take care not to damage the environment and
respect natural surroundings.
Note
Only drive where access by motor vehicles is
permitted and keep to the marked tracks and
routes.
Driving tips
When driving on rough tracks always drive slowly
and be aware of possible hazards.
Please observe the following precautions if you
drive the vehicle on unsurfaced tracks or off-

road:

•
When driving off-road you are advised to avoid
tracks or terrain which are not suited to the de­
sign of the car and your own driving skills and
experience. Do
not
take risks.

•
Drive slowly and be ready for possible hazards.

•
Be aware of the maximum ground clearance of
your vehicle. The figure in actual conditions
may be different, depending on the type of sur­

face,
the surrounding terrain and the load be­
ing carried. With certain types of suspension,
such as sports suspension, the ground clear­
ance is reduced. It is the responsibility of the
driver to decide whether or not the vehicLe is
capable of safely negotiating a particular situa­

tion.

•
Activate the ESC off-road mode if required

^>page
146.
Unsurfaced tracks
On unfamiliar roads and off-road terrain, drive
slowly and be prepared for unexpected obstacles,
such as pot-holes, rocks or tree stumps, etc.
To prevent ground contact and possible damage
to the underside, do not drive the bottom of your
vehicle directly over raised obstacles. Instead,
drive the wheels on one side of the car up and
across the top of the obstacle.
When driving over sand or soft mud, maintain a
moderate speed and avoid stopping if possible.
Driving through water on roads
Please observe the important safety warnings on

Automatic gearbox
Introduction
Applies to: vehicles with automatic gearbox
The automatic gearbox is controlled electronical­
ly. The gearbox changes up and down automati­
cally.
When you drive at moderate speeds the gearbox
will select the most economical shift pro­
gramme. It will then change up early and delay
the downshifts to give better fuel economy.
If you drive at higher speeds with heavy accelera­

tion,
if you open the throttle quickly, or if you use
the kick-down or the car's maximum speed, the
gearbox will automatically select the more "spor­
ty" shift programmes when the selector lever is
in position S.
If desired, you can also select the gears manually
(tiptronic mode)

Checking and topping up fluids
months so that you can continue to operate your
vehicle reliably. Ask at your filling station wheth­
er the diesel fuel available there is suitable for
the current conditions and for the temperatures
which could potentially occur.
© CAUTION
- Never use FAME fuels (biodiesel), petrol,
heating oil, thinners or any other fuels or
additives, as these could cause serious dam­
age to the fuel system and the engine.
- Never start the engine if
you
fill up with the
wrong type of
fuel,
as this could damage
the fuel system and the engine. Obtain pro­
fessional assistance.

- If, in exceptional circumstances, you have
to

carry
a
spare fuel canister, please observe
the following warnings:
- Never
filL
fuel into the spare fuel canister
with the canister placed in or on top of the
vehicLe. An electrostatic charge could
build up during filling, causing the fuel va­
pour to ignite
-
risk of explosion! Always
place the canister on the ground to fill
it.

- Insert the filler nozzle as far as possibLe
into the spare fuel canister.
-
If
the spare fuel canister is made of metal,
the filler nozzle must be in contact with

Emission controL
systems
Catalytic converter
Applies to: vehicles with petrol engine
The vehicle must only be used with unleaded pet­

rol,
otherwise the catalytic converter will be ir­
reparably damaged.
Never allow the fuel tank to run completely dry,
as the irregular supply of fuel can cause misfir­

ing.
This allows unburnt fuel to enter the exhaust

system,
which can cause overheating and dam­
age to the catalytic converter.
Diesel particulate filter
Applies to: vehicles with diesel engine
The diesel particulate filter can filter out almost
all soot particles contained in the exhaust gas. In
normal driving conditions the filter is self-clean­

ing.
Should the self-cleaning function of the filter
not be able to operate, e.g. when the vehicle is
continuously used only for short trips, the filter
becomes obstructed with soot and the indicator

A WARNING
The exhaust system is very hot when the
vehi­

cle is being driven and after the engine has
been switched off.
- Never touch the tailpipes when they are hot
- risk of burns!
- Because of the high temperatures which can
occur in the emission controL system, do not
park the vehicle where the exhaust can
come into contact with flammable materials
under the car (e.g. on grass or at the forest
edge) - risk of fire!
- Do not apply any underseal agents in the
area around the exhaust system - risk of

fire!
