Automatic gearbox
130Automatic gearboxmultitronic
®
Applies to vehicles: with multitronic®IntroductionThe vehicle is equipped with an electronically controlled continu-
ously variable transmission (multitronic
®). Unlike conventional
automatics, the gear ratios are not shifted in fixed steps but contin-
uously variable. This gives smoother transmission and makes for
better fuel economy.
The gearbox selects the gear ratio and shifts up or down automati-
cally according to the gear change programmes stored in the
control unit ⇒page 133, “Dynamic gear control program (DCP)”.
The gearbox also has the tiptronic manual shift feature. This system
allows the driver to select gears manually if required ⇒ page 134.
Please note that on vehicles with a multitronic gearbox, torque is
transmitted via a multi- plate clutch, and not via a torque converter
as on conventional automatics. This means that the car will not
“creep” as much as conventional automatics when the engine is
idling if you stop temporarily with the selector lever in position D, S
or R.
Applies to vehicles: with multitronic®General notes on using multitronic
®
The transmission ratio is varied continuously.Driving away from a standstill
– Press and hold the brake pedal.
– Press and hold the interlock button (the button in the selector lever handle), move the selector lever to the
desired position, for instance D, and release the interlock
button.
– Wait for the gearbox to engage the gear (a slight move- ment can be felt).
– Release the brake and press the accelerator ⇒.
Stopping briefly
– Apply the foot brake to hold the vehicle when stationary (for instance at traffic lights).

– Press the brake pedal and at the same time press in the
interlock button.Automatic selector lever lock
The selector lever is locked in the P and N positions when the igni-
tion is on. The brake pedal must be depressed before the lever can
be moved out of either of these positions. The following message
appears in the instrument display as a reminder for the driver when
the selector lever is in position P or N:
WHEN STATIONARY APPLY FOOTBRAKE WHILE SELECTING GEAR.
The selector lever lock only works if the vehicle is stationary or
driving at speeds up to 5 km/h. At higher speeds the selector lever
lock in the N position is disengaged automatically.
The selector lever lock is not engaged if the selector lever is moved
quickly through position N (e.g. when shifting from R to D). This
makes it possible, for instance, to “rock” the vehicle backwards and
forwards if it is stuck in snow or mud. The selector lever lock
engages automatically if the brake pedal is not depressed and the
lever is in position N for more than about a second.
Interlock button
The interlock button on the selector lever handle prevents the driver
from inadvertently engaging particul ar gears. Press the button in to
disengage the selector lever lock. Th e illustration shows the selector
lever positions in which the button has to be pressed, highlighted in
colour ⇒page 132, fig. 146.
Safety interlock for ignition key
The key can only be withdrawn with the ignition switched off and
the selector lever in position P. When the ignition key is removed,
the selector lever is locked in position P.
Applies to vehicles: with multitronic®Kick-down feature
The kick-down feature is designed to give maximum
acceleration.When the accelerator pedal is pressed right down past the point of
resistance at full throttle, the gearbox will select a lower gear,
depending on road speed and engine speed. While you keep the
accelerator depressed the engine speed is automatically controlled
to give your vehicle maximum acceleration.
WARNING
Please note that if the road surf ace is slippery or wet, the kick-
down feature could cause the driv ing wheels to spin, which could
result in skidding.Applies to vehicles: with multitronic®Dynamic gear control program (DCP)
The multitronic
® gearbox is controlled electronically.
The vehicle is equipped with an electronically controlled gearbox.
The gear ratios are selected automatically according to preset gear-
shift programmes.
When you drive at moderate speeds the gearbox will select the most
economical shift programme. It will then change up early and delay
the downshifts to give better fuel economy.
If you drive at higher speeds with heavy acceleration, if you open the
throttle quickly, or if you use the kick-down or the car's maximum
speed, the gearbox will automaticall y select the more “sporty” shift
programmes.
The gearbox is self-adapting, and continuously selects the most
suitable shift programme. At the same time, the driver can also
make the gearbox switch to a more "sporty" programme by pressing

Technical data
Your vehicle and the environmentRunning inA new vehicle should be run in over a distance of 1,500 km. For the
first 1,000 km the engine speed should not exceed 2/3 of the
maximum permissible engine speed – do not use full throttle and do
not tow a trailer or caravan. From 1,000 to 1,500 km you can gradu-
ally increase the engine rpm and road speed.
During its first few hours of running, the internal friction in the
engine is greater than later on when all the moving parts have
bedded down.
How the vehicle is driven for the first 1,500 km also influences the
engine quality. After the first 1,500 km you should continue driving
at moderate engine speeds, in particular when the engine is cold.
This helps to reduce wear and tear on the engine and increases the
potential mileage which can be covered by the engine.
You should also avoid driving with the engine speed too low.
Change down to a lower gear when the engine no longer runs
“smoothly”. Excessively high engine speeds are prevented by an
automatic rev limiter.Emission control systemsCatalytic converter
Applies to vehicles with petrol engine: The vehicle must only be
used with unleaded petrol, otherwise the catalytic converter will be
destroyed.
Never run the tank completely dry. The irregular fuel supply can
cause misfiring, which would allow unburnt fuel to enter the
exhaust system, which could cause overheating and damage 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-cleaning. 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 symbol
 for the diesel
particulate filter lights up ⇒page 37 .
WARNING
•
Because of the high temperatures which can occur in the emis-
sion control system (catalytic converter or diesel particulate
filter), 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). - Fire hazard!
•
Do not apply any underseal agen ts in the area around the
exhaust system - fire hazard!
Driving abroadChanging over headlight dip settings
The asymmetric low beams of the headlights are designed to light
up the near side of the road more intensely. If you drive in a country
where traffic drives on the opposite side of the road to the home
country, this will dazzle oncoming traffic.
Headlights with halogen bulbs: To avoid dazzling oncoming traffic
you can apply opaque stickers to certain parts of the headlight
lenses.
Headlights with xenon gas-discharge bulbs*: The headlight dip
settings must be changed to avoid dazzling oncoming traffic. For

Unleaded petrol
A car with catalytic converter must not be run with leaded petrol
⇒ page 205 . Before driving abroad make sure that unleaded petrol
is available there.How to improve economy and minimise pollutionFuel economy, environmental impact and wear on the engine,
brakes and tyres depend largely on the way you drive the vehicle. By
adopting an economical driving style and anticipating the traffic
situation ahead, you can reduce fuel consumption by 10-15%. The
following section gives you some tips on lessening the impact on
the environment and reducing your operating costs at the same
time.
Anticipate well in advance
A car uses most fuel when accelerating. If you anticipate hazards
and speed changes well in advance, you will need to brake less and
thus accelerate less. Wherever possible, let the car slow down grad-
ually with a gear engaged , for instance when you can see that the
next traffic lights are red. This takes advantage of the engine
braking effect, reducing wear on the brakes and tyres. Emissions
and fuel consumption will drop to zero due to the overrun fuel cut-
off.
Change gear early to save fuel
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:
Shift up to second gear as soon as possible. If
possible, we recommend shifting up to the next gear at approx.
2,000 rpm.
Automatic gearbox: Press the accelerator slowly and avoid using
the “kick-down” feature.
Avoid driving at high speed
Avoid travelling at top speed. Fuel consumption, exhaust emissions
and noise levels all increase very rapidly at higher speeds. Driving at
moderate speeds will help to save fuel.
Do not let the engine idle for longer than necessary
It is worthwhile switching off the engine when waiting in a traffic
jam, at level crossings or at traffic lights with a long red phase. The
fuel saved after only 30 - 40 seconds is greater than the amount of
fuel needed to restart the engine.
The engine takes a very long time to warm up when it is running at
idling speed. Mechanical wear and pollutant emissions are also
especially high during this initial warm-up phase. It is therefore best
to drive off immediately after starting the engine. Avoid running the
engine at high speed.
Regular servicing
Regular servicing can establish a basis for good fuel economy
before you start driving. A well-serviced engine gives you the
benefit of improved fuel efficiency as well as maximum reliability
and an enhanced resale value. A badly tuned engine can consume
up to ten percent more fuel than necessary.
Avoid short trips
The engine and emission control system need to reach their proper
working temperature in order to minimise fuel consumption and
emissions.
A cold engine uses disproportionately more fuel. The engine only
reaches its working temperature after about four kilometres, when

fuel consumption will return to a normal level. This is the reason
why we recommend avoiding short trips wherever possible.
Maintain the correct tyre pressures
Always make sure the tyres are inflated to the correct pressures
⇒
page 243 to save fuel. If the tyre pressures are just 0.5 bar too low,
this can increase the fuel consumption by as much as 5 %. Due to
the greater rolling resistance, under-inflation also increases tyre
wear and impairs handling.
Do not use winter tyres all through the year; they will increase fuel
consumption by up to 10 %.
Avoid carrying unneccessary loads
Every kilo of extra weight will increase the fuel consumption, so it is
worth checking the luggage compartment occasionally to make
sure that no unnecessary loads are being transported.
A roof carrier is often left in place for the sake of convenience, even
when it is no longer needed. At a speed of 100-120 km/h your car will
use about 12 % more fuel as a result of the extra wind resistance
caused by the roof carrier - even when it is empty.
Save electrical energy
The engine drives the alternator to generate electricity. This means
that fuel consumption rises when more power is required for elec-
trical equipment. Switch off electrical equipment when it is not
needed. Electrical equipment which uses a lot of electricity includes
the blower (at a high se tting), the rear window heating and the seat
heating*.

Technical data
Fuel and filling the tankPetrolApplies to vehicles: with petrol enginePetrol grade
The correct grade of petrol is listed inside the fuel tank
flap.The vehicle is equipped with a catalytic converter and must only be
run on unleaded petrol . Unleaded petrol must comply with the
European EN 228 standard. The petrol grades have different octane
ratings (RON). If, in exceptional circumstances, the correct octane
rating is not available, please note the following:•
For engines which require Premium unleaded petrol (95 RON)
according to ⇒page 295, “Performance, weights and dimensions”:
Regular unleaded fuel with 91 RON can also be used. This will,
however, result in a slight loss of power.
•
For engines which require Super Plus unleaded petrol (98 RON)
according to ⇒page 295, “Performance, weights and dimensions”:
Premium unleaded fuel with 95 RON can also be used. This can,
however, result in a slight loss of power under certain driving condi-
tions. – If premium unleaded petrol is not available, the engine can
be run on regular unleaded petrol with 91 RON as an emergency
measure . In this case only use moderate engine speeds and a light
throttle. Avoid using full throttle. Fi ll up with premium or Super Plus
petrol as soon as possible.Caution
•
Petrol complying with the EN 228 standard can contain small
quantities of ethanol. However, “bioethanol fuels”, which are
retailed under various different names such as E50 and E85, and
which contain a large proportion of ethanol, must not be put into
the vehicle, as this would damage the fuel system.
•
Even one tankful of leaded fuel would permanently impair the
efficiency of the catalytic converter.
•
High engine speed and full throttle can damage the engine when
using petrol with an octane rating lower than the correct grade for
the engine.
DieselApplies to vehicles: with diesel engineDiesel fuel
Please note the information on the inside of the fuel tank
flap.Diesel fuel must comply with the European EN 590 standard. It must
have a cetane number (CN) of at least 51. The cetane number indi-
cates the ignition quality of the diesel fuel.
Winter-grade diesel
Diesel fuel can thicken in winter. For this reason petrol stations in
some countries also offer winter diesel.
Caution
•
The vehicle is not designed for the use of biodiesel (FAME fuel).
The fuel system would be damaged if you use biodiesel.
•
Do not mix fuel additives (“thinners”, petrol or similar additives)
with the diesel fuel.
•
If poor-quality diesel fuel is used, it may be necessary to drain
the water separator on the fuel filter more frequently than is speci-
fied in the Service Schedule. We recommend having this done by a
specialist workshop. If water is allowed to collect in the filter, this
can cause engine performance problems.

Fuel and filling the tank
228Filling the tankFilling the tankThe flap that covers the tank cap is unlocked and locked
automatically by the central locking.
Unscrewing the tank cap
– Press the left side of the flap to open it ⇒fig. 218 -arrow-.
– Unscrew the tank cap anti-clockwise.
– Hook the cap onto the open flap ⇒fig. 219. Closing the tank cap
– Screw on the tank cap clockwise until it cannot be turned
further.
– Press the left side of the flap to close it (you should hear it click into place).
When the automatic filler nozzle is operated correctly it will switch
itself off as soon as the tank is “full”. Do not try to put in more fuel
after the nozzle cuts out, as this will fill the expansion chamber in
the fuel tank.
The correct fuel grade for your vehicle is given on a sticker on the
inside of the tank flap. Further notes on fuel ⇒page 227 .
The tank capacity of your vehicle is given in the Technical data
section ⇒page 293 .
WARNING
Fuel is highly inflammable and can cause serious burns and other
injuries.•
For safety reasons always swit ch off the auxiliary heating*
before refuelling the vehicle.
•
For safety reasons we do not recommend carrying a spare fuel
canister in the vehicle. The cani ster could become damaged in an
accident and leak.
•
Observe all relevant statutory regulations on using, storing and
transporting spare fuel canisters.
•
When filling your tank or a spare fuel canister with fuel, do not
smoke and keep away from naked flames. Risk of explosion!
•
If, in exceptional circumstances, you have to carry a spare fuel
canister, please observe the following warnings:
−Never fill fuel into the spare fu el canister with the canister
placed in or on top of the vehicle. An electrostatic charge could
build up during filling, causing th e fuel vapour to ignite. Danger
of explosion. Always place the canister on the ground to fill it.

Driving tips
General maintenance
Self-help
Technical data
−
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 the canister during filling. This helps
prevent an electrostatic charge building up.
− Make sure you never spill fuel in the vehicle or in the luggage
compartment. Fuel vapour is ex plosive. Risk of fatal accident!
Caution
•
If any fuel is spilt onto the vehicle, it should be removed immedi-
ately, as it could otherwise damage the paintwork.
•
Never run the tank completely dry. If there is an irregular fuel
supply, misfiring can occur. As a result unburnt fuel can enter the
exhaust system and cause damage to the catalytic converter(s).
•
When filling the fuel tank after having run it completely dry on a
vehicle with a diesel engine the ignition must be switched on for at
least 30 seconds without starting the engine. When you then start
the engine it may take longer than normal (up to one minute) for the
engine to start firing. This is because air needs to be bled from the
fuel system while starting.For the sake of the environment
Do not try to put in more fuel after the automatic filler nozzle has
switched off; this may cause the fuel to overflow if it becomes warm.
Note
The tank flap is not locked when you lock the vehicle from the
inside.
Releasing the tank flap manually
The tank flap can be released manually if the central
locking system should fail to operate.The manual release mechanism is located behind the side
trim on the right of the luggage compartment.
– Open the right-hand side trim.
– Release the ring from its holder and pull the ring
⇒ fig. 220. You should now be able to open the tank flap
in the usual way ⇒page 228 .

Working on components 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 fire when working in the engine compartment
(e.g. when checking and refilling fluids). Always observe the warn-
ings listed below and follow al l normal safety precautions. The
engine compartment of any motor vehicle is a potentially
hazardous area . ⇒ .
WARNING
•
Switch off the engine.
•
Remove the ignition key.
•
Apply the parking brake.
•
Put the gear lever in neutral or selector in P.
•
Wait for the engine to cool down.
•
Keep children away from engine compartment.
•
Never spill fluids on hot engine components. These fluids can
cause a fire (e.g. radiator anti-freeze).
•
Take care not to cause short circ uits in the electrical system,
especially when working on the battery.
•
Do not touch the radiator fan when the engine is hot. The fan
may start running suddenly.
•
Do not unscrew the cap on the ex pansion tank when the engine
is hot. The cooling system is under pressure.
•
Protect face, hands and arms by covering the cap with a large,
thick rag to protect against escaping coolant and steam.
•
If any tests have to be performed with the engine running,
there is an extra safety risk from the rotating parts, such as the
drive belts, alternator and radiator fan, etc., and from the high-
voltage ignition system.
•
Vehicles with automatic gearbox: Never open the throttle inad-
vertently (for instance by hand from the engine compartment) if a
gear is engaged while the vehicle is stationary with the engine
running. The vehicle could otherwise start moving immediately
and possibly cause an accident.
•
Observe the following a dditional warnings if work on the fuel
system or the electrical system is necessary:
−Always disconnect the battery.
− Do not smoke.
− Never work near naked flames.
− Always keep an approved fire extinguisher immediately
available.Caution
When topping up fluids make sure the correct fluid is put into the
correct filler opening. This can otherwise cause serious malfunc-
tions or engine damage.
For the sake of the environment
Inspect the ground un derneath your vehicle regularly so that any
leaks are detected at an early stag e. If you find oil spots or other
fluids, have your vehicle inspected by a qualified workshop.
Note
On right-hand drive vehicles* some of the containers/ reservoirs
mentioned below are located on the other side of the engine
compartment.
