If you select a gear which is lower than the gear shown on the instrument
panel display ⇒ Fig. 150, the gearbox will only shift down when there is no
longer a risk of over-revving the engine.
When the vehicle slows down (for instance when braking), the gearbox au-
tomatically shifts down into the next gear when the minimum engine speed
is reached.
Changing down to a lower gear increases the engine braking effect on
downhill gradients.
When the accelerator pedal is pressed right down past the point of resist-
ance at full throttle, the gearbox will select a lower gear ratio, depending on
road speed and engine speed.
Back-up programme
A back-up system is in place if a fault should occur in the
control system.
The automatic gearbox switches to the back-up programme if a fault should
occur in the control system. This is indicated by a gear pinion symbol which
lights up on the instrument panel display.
It is still possible to move the selector lever to all positions. The manual
shift programme (tiptronic) is not available when the back-up programme is
active.
Vehicles with tiptronic gearbox: When the selector lever is in position D or S
or in the manual shift programme, the gearbox will remain in 3rd gear if 1st,
2nd or 3rd gears were engaged when the fault occurred. The gearbox will
remain in 5th gear if 4th, 5th or 6th gears were engaged. The gearbox will
then engage 3rd gear when you drive away from a standstill or after the en-
gine is restarted. It will still be possible to use reverse gear in the normal way. However, the
electronic lock for reverse gear will be switched off.
CAUTION
Should the gearbox ever switch into the back-up programme, you should
take the vehicle to a technical service or specialised workshop as soon as
possible.
Steering wheel with paddle levers
The paddle levers on the steering wheel enable the driver to
manually select pre-programmed ratios or gears.

196Driving and the environment
Diesel engine particulate filter*
The diesel engine particulate filter eliminates soot produced
by burning diesel.
The diesel engine particulate filter eliminates most of the soot from the ex-
haust gas system. Under normal driving conditions, the filter cleans itself. If
the driving conditions do not allow the filter to clean itself (for example,
multiple short trips) the filter will be obstructed by dust and pollen and the
indicator for the diesel engine particulate filter indicator will light up.
This does not represent a fault, it is a warning that indicates that the filter
has not been able to regenerate automatically and that you must carry out a
cleaning cycle, as indicated in ⇒ page 81.
WARNING
● The diesel engine particulate filter may reach extremely high temper-
atures; the vehicle should be parked so that the exhaust pipe does not
come into contact with flammable materials underneath the vehicle. Oth-
erwise there is a risk of fire.
CAUTION
● Your vehicle is not designed to use biodiesel fuel. Never, under any cir-
cumstances refuel with biodiesel. The use of biodiesel fuel could damage
the engine and the fuel system. The addition of biodiesel to diesel by the
diesel producer in accordance with standard EN 590 is authorised and will
not cause damage to the engine or the fuel system.
● Using diesel fuel with a high sulphur content may significantly reduce
the useful life of the diesel particulate filter. Your Technical Service will be
able to tell you which countries have diesel with a high sulphur content. Economical and environmentally friendly
driving
Economical and environmentally friendly driving
Fuel consumption, environmental pollution and wear to the engine, brakes
and tyres depends in large part on your driving style. By adopting an eco-
nomical driving style and anticipating the traffic situation ahead, you can
easily reduce fuel consumption by 10-15%. Some tips on how to help you
reduce pollution while saving money are listed below.
Drive anticipating the traffic situation
A vehicle uses most fuel when accelerating. When you anticipate the situa-
tion, you have to brake less often and, thus, accelerate less. If it is possible,
let the vehicle roll with a
gear engaged, for example, if you see a red light
ahead. The braking effect achieved in this way helps to reduce the wear of
brakes and tyres; emissions and fuel consumption are reduced to zero (dis-
connection due to inertia).
Change gear early to save energy
An effective way of saving fuel is to change up quickly through the gears.
Running the engine at high rpm in the lower gears uses an unnecessary
amount of fuel.
Manual gearbox: Change from first to second gear as quickly as possible.
We recommend that, whenever possible, you change to a higher gear upon
reaching 2000 rpm. Follow the “recommended gear” indication that ap-
pears on the instrument panel ⇒ page 74.
Avoid driving at high speed
We advise you not to drive at the top speed permitted by the vehicle. Fuel
consumption, exhaust emissions and noise levels all increase very rapidly
at higher speeds. Driving at moderate speeds will help to save fuel.

under the bonnet
Before opening the bonnet make sure that the windscreen wiper
arms are not lifted away from the glass. Otherwise the paint may
be damaged.
– Lift the bonnet slightly ⇒
.
– Press the release catch under the bonnet upwards ⇒ Fig. 168.
This will release the arrester hook under the bonnet.
– Open the bonnet.
The bonnet is held in position by a gas-filled strut.
WARNING
Never open the bonnet if you see steam or drips of coolant being re-
leased from the engine compartment. Failure to comply could result in
burns. Wait until no steam or coolant can be seen before opening the
bonnet.
Work in the engine compartment
Extra caution is necessary when working on components in
the engine compartment.
Always be aware of the danger of injury and scalding as well as the risk of
accident or even fire when working in the engine compartment (e.g. when
checking and refilling fluids). Always observe the warnings listed below
and follow all general safety precautions. The engine compartment of the
vehicle is a potentially hazardous area ⇒
WARNING
● Switch the engine off.
● Remove the ignition key.
● Apply the handbrake firmly.
● If your vehicle is equipped with a manual gearbox, place the gear lev-
er in neutral. If you are driving an automatic vehicle, place the selector
lever in position P.
● Wait for the engine to cool down.
● Children should not be allowed to approach the engine compartment.
● Never spill liquids used for vehicle operation on the engine compart-
ment, as these may catch fire (e.g. coolant).
● Take care not to cause short circuits in the electrical system, especial-
ly when working on the battery.
● Never touch the radiator fan while the engine is hot, as the fan could
start up suddenly.
● Never open the expansion tank when the engine is hot. The cooling
system is under pressure.
● Protect face, hands and arms from any hot steam or hot coolant fluid
released by covering the cap with a large, thick rag when opening the ex-
pansion tank.

290If and when
Do not pull too hard with the towing vehicle and take care to avoid jerking
the tow rope. When towing on an unpaved road, there is always a risk of
overloading and damaging the anchorage points.
The ignition of the vehicle being towed must be switched on to prevent the
steering wheel from locking and also to allow the use of the turn signals,
horn, windscreen wipers and washers.
As the brake servo does not work if the engine is not running, you must ap-
ply considerably more pressure to the brake pedal than you normally would.
As the power assisted steering does not work if the engine is not running,
you will need more strength to steer than you normally would.
Towing vehicles with an automatic gearbox
● Put the selector lever into position “N”.
● Do not drive faster than 50 km/h.
● Do not tow further than 50 km.
● If a breakdown vehicle is used, the vehicle must be towed with the front
wheels raised.
Note
● Observe legal requirements when towing or tow-starting.
● Switch on the hazard warning lights of both vehicles. However, observe
any regulations to the contrary.
● For technical reasons, vehicles with an automatic gearbox must not be
tow-started.
● If damage to your vehicle means that there is no lubricant in the gear-
box, you must raise the drive wheels while the vehicle is being towed.
● If the vehicle has to be towed more than 50 km, the front wheels should
be raised during towing, and towing should be carried out by a qualified
person. ●
The steering wheel is locked when the vehicle has no electrical power.
The vehicle must then be towed with the front wheels raised. Towing should
be carried out by a qualified person.
● The towing eye should always be kept in the vehicle. Please refer to the
notes ⇒ page 289, Tow-starting.

Information on fuel consumption
Fuel consumption
The consumption and emission details shown on the vehicle
data sticker differ from one vehicle to another.
The vehicle's fuel consumption and CO 2 emissions can be consulted on the
vehicle data sticker in the spare wheel well, inside the luggage compart-
ment and on the rear cover of the Maintenance Programme.
The fuel consumption and CO 2 emission values refer to the weight category
assigned to your vehicle according to the engine and gearbox combination,
as well as the specific equipment fitted, and is only used to compare be-
tween the different models.
The fuel consumption and CO 2 emissions do not depend only on the per-
formance of the vehicle, they can also differ from the established values de-
pending on other factors such as driving style, road conditions, traffic con-
ditions, environmental conditions, load and number of passengers.
Calculation of fuel consumption
The consumption values have been calculated based on measurements per-
formed or supervised by certified CE laboratories according to the latest ver-
sion of directives 715/2007/EC and 80/1268/CEE (for more information
consult the European Union Publications Office at EUR-Lex: © European Un-
ion, http://eur-lex.europa.eu/en/index.htm) and are valid for the kerb
weight indicated for the vehicle.
Note
In practice, and considering all the factors mentioned here, consumption
values can differ from those calculated in the current European regulations. Weights
Kerb weight refers to the basic model with a fuel tank filled to 90% capacity
and without optional extras. The figure quoted includes 75 kg to allow for
the weight of the driver.
For special versions and optional equipment fittings or for the addition of
accessories, the weight of the vehicle will increase
⇒
.
WARNING
● Please note that the centre of gravity may shift when transporting
heavy objects; this may affect the vehicle's handling and lead to an acci-
dent. Always adjust your speed and driving style to suit road conditions
and requirements.
● Never exceed the gross axle weight rating or the gross vehicle weight
rating. If the allowed axle load or the allowed total weight is exceeded,
the driving characteristics of the vehicle may change, leading to acci-
dents, injuries and damage to the vehicle.
Towing a trailer Trailer weights
Trailer weight
The trailer weights and drawbar loads approved are selected in intensive tri-
als according to precisely defined criteria. The approved trailer weights are
valid for vehicles in the EU for maximum speeds of 80 km/h (in certain cir-
cumstances up to 100 km/h). The figures may be different in other coun-
tries. All data in the official vehicle documents take precedence over these
data ⇒
