Brakes
What has a negative effect on braking efficiency?
Wear-and-tear
Wear-and-tear to the brake pads is greatly dependent on the operating conditions of the vehicle and your style of driving. Particularly if you drive a great deal in towns and over short distances or if you adopt a sporty style of driving, it may be neces- sary to have the thickness of the brake pads inspected at a specialist garage between the service inspections.
Wet roads or road salt
There may be a certain delay before the brakes take full effect under certain condi- tions such as when driving through water, during heavy rain showers or after the vehicle has been washed in an automatic vehicle wash, since the brake discs and brake pads may be moist or even have a coating of ice on them in winter. You should dry the brakes as soon as possib le (by applying and releasing the brakes several times, if the road conditions and the traffic situation allows it).
There also may be a certain delay before the full braking efficiency is available when driving on roads which have been treated wi th road salt if you have not used the brakes for some considerable time beforeha nd. The layer of salt on the brake discs and brake pads must first be rubb ed off when you apply the brakes.
Corrosion
Corrosion on the brake discs and dirt on th e bake pads occur if the vehicle has been parked for a long period and if you do not make much use of the braking system.
We recommend cleaning the brake discs by firmly applying the brakes at a fairly high speed if you do not make much use of the braking system or if surface corro- sion is present ⇒.
Faults in the brake surface
If you notice that the braking distance has suddenly become longer and that the brake pedal can be depressed further, it is possible that a brake circuit of the dual- circuit brake system has failed. Drive, in such cases, to the nearest specialist garage without delay in order to have the problem rectified. Drive at a reduced speed while on your way to the dealer and adapt your style of driving to the higher brake pedal pressure required.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system. The level of the brake fluid is monitored electronically ⇒page 28, “Brake system ”.
WARNING
•Only apply the brakes for the purpose of drying and cleaning the brake discs if the traffic conditions permit this. Do not place any other road users in jeopardy.
•When retrospectively mounting a front spoiler, solid wheel hubs etc. one must ensure that the air supply to the front wheel brakes is not reduced otherwise the braking sy stem could run too hot.
•Allow for the fact that new brake pads do not achieve their full braking efficiency until approximately 200 kilo metres. New brake pads must be first “run in” before they develop their optimal friction force. You can, however, compensate for this slightly reduced braking force by increasing the pres- sure on the brake pedal. This guidelin e also applies to any new brake pads installed at a future date.
Caution
•Never allow the brakes to ru b by applying slight pressure if you do not wish to brake the vehicle. This causes the brakes to overheat and can also result in a longer braking distance and excessive wear.
•Before negotiating a steep downhill section, please reduce your speed and shift down into the next lower gear (manual ge arbox) or select a lower driving stage (automatic gearbox). This enables you to make full use of the braking power of the vehicle and reduces the strain on the brakes . Any additional braking should be done intermittently, not continuously.
Brake booster
The brake booster boosts the pressure which you generate with the brake pedal. The necessary pressure is only gene rated when the engine is running.

Driving and the Environment
The first 1 500 kilometres and then afterwards
A new engine
The engine has to be run in during the first 1 500 kilometres.
Up to 1 000 kilometres
– Do not drive faster than 3/4 of the mamimum speed of the gear in use,
that is 3/4 of the maximum permissible engine speed.
– Do not use full throttle.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1 000 up to 1 500 kilometres
– Increase the power output of the engine gradually up to the full
speed of the gear engaged, that is up to the maximum permissible
engine revolutions.
During the first operating hours the engine has higher internal friction than later until all of the moving parts have harmonized. The driving style which you adopt during the first approx.1 500 kilometres plays a decisive part in the success of running in your car.
You should not drive at unnecessarily high engine revolutions even after the running-in period is complete. The maximum permissible engine speed is marked by the beginning of the red zone on the scale of the revolutions counter. Shift up into the next higher gear on a vehicle fitted with manual gearbox before the red zone is reached. Extremely high engine revolutions are automatically governed, by the way.
For a vehicle fitted with a manual gearbox the converse situation also applies: Do not drive at engine revolutions which are too low. Shift down as soon as the engine is no longer running smoothly.
Caution
All the speed and engine revolution figure s apply only when the engine is at its normal operating temperature. Never rev up an engine which is cold, neither when the vehicle is stationary nor when driving in individual gears.
For the sake of the environment
Not driving at unnecessarily high engine revolutions and shifting to a higher gear as early as possible are ways to minimise fu el consumption and operating noise levels and protects the environment.
New tyres
New tyres have to be “run in” since they do not offer optimal grip at first. You should take account of this fact for the first 500 kilometres and drive particularly carefully.
New brake pads
Allow for the fact that new brake pads do not achieve their full braking efficiency until approximately 200 kilometres. New brake pads must be first “run in” before they develop their optimal friction force. You can, however, compensate for this slightly reduced braking force by increa sing the pressure on the brake pedal.
This guideline also applies to any new brake pads installed at a future date.
During the running-in period , you should avoid excessive stresses on the brakes. This includes, for example, violent braking, particularly from very high speeds, and also when crossing mountain passes.

The fuel consumption can naturally also be influenced by factors which are beyond the driver's control. It is, for example, normal for the fuel consumption to increase in winter and under worsened conditions such as poor road conditions, towing a trailer, etc.
The technical requirements for low fuel usage and economic efficiency of the vehicle have already been built into the ve hicle at the works. Special attention has been given to minimising ne gative effects on the environment. It is necessary to take note of the guidelines given in this chapter in order to make best use of these characteristics and to maintain their effectiveness.
Looking ahead when driving
A vehicle's highest fuel consumption occurs it accelerates.
Avoid accelerating and brakin g unnecessarily. If you drive with forsight you will not need to brake so often and will also then not have to accelerate so much. Let your vehicle coast to a stop, for example, if this is possible, when you see that the next set of traffic lights is at red.
Shifting gears and saving energy
Shifting up early saves on fuel.
Manual gearbox
– Drive no more than about one length of your vehicle in first gear.
Always shift up into the next higher gear at approx. 2 000 to 2 500 revs.
Automatic gearbox
– Depress the accelerator pedal slowly. Do not depress it beyond the
kickdown position, however.
An effective way of achieving good fuel economy is to shift up early. You will consume more fuel if you drive at unnecessa rily high revolutions in any given gear.
The ⇒fig. 149 shows the ratio of fuel consumption to the speed of your vehicle in the relevant gears. Fuel consumption in 1st gear is the highest and in 5th gear is the lowest.
Note
•The optimal engine speed should be obtained when accelerating, in order to avoid a high fuel consumption and resonance of the vehicle.
•Also use the information supplied by the multi-functional indicator* ⇒ page 13.
Avoiding full throttle
Driving more slowly means saving fuel.

Inspecting and Replenishing174
– Grip the bonnet and lift it up.
– Take the bonnet support out of its holder and set it in the opening
designed for it ⇒page 173, fig. 156.
Closing the bonnet
– Lift the bonnet slightly and unhook the bonnet support. Press the
bonnet support into the hold er designed to hold it.
– Allow the bonnet to drop from a height of about 30 cm into the lock -
bonnet do not press down on it!
WARNING
•Never open the bonnet if you see that steam or coolant is flowing out of the engine compartment - risk of scaldi ng! Wait long enough until the steam or coolant has stopped escaping.
•For safety reasons, the bonnet must always be properly closed when driving. One should therefore check that the lock has in fact engaged prop- erly after closing the bonnet.
•Stop your vehicle i mmediately while driving if you notice that the lock is not properly engaged and close the bonn et properly - risk of an accident!
Caution
•Before opening the bonnet, ensure that the arms of the windscreen wipers are correctly in place against the windscreen. Otherwise, there is a risk of damage to the paintwork.
Working in the engine compartment
Particular care is required when ca rrying out any work in the engine
compartment!
There is a risk of injuries, scalding, accidents and fire when working in the engine compartment, e.g. inspecting an d replenishing oil and other fluids. For
this reason, it is essential to comply with the warning instructions stated below and with the general applicable rules of safety. The engine compart-ment of your car is a hazardous area ⇒.
WARNING
•Never open the bonnet if you see that steam or coolant is flowing out of the engine compartment - risk of scaldi ng! Wait long enough until the steam or coolant has stopped escaping.
•Switch off the engine and pull out the ignition key.
•Apply the handbrake firmly.
•If your vehicle is fitted with a manual gearbox, move the gearshift lever into Neutral, or if it is fitted with automatic gearbox, move the selector lever into position P.
•Allow the engine to cool down.
•Keep children clear of the engine compartment.
•Do not touch any hot engine parts - risk of burns!
•Never spill oil and other fluids over the hot engine. Such fluids (e.g. the antifreeze contained in the coolant) may ignite!
•Avoid short circuits in the electrical system - particularly on the battery.
•Never place your hand into the radiator fan as long as the engine is still warm. The fan might suddenly start running!
•Never open the cap of the coolant expa nsion bottle as long as the engine is still warm. The cooling system is pressurized!
•Cover over the cap of the coolant expansion reservoir with a large cloth when opening it as protection for your face, hands and arms from hot steam or hot coolant.
•Do not let objects, such as e.g cleaning cloth or tools lie in the engine compartment.
•If you wish to work under the vehicl e, you must secure the vehicle from rolling away and support it with suitable supporting blocks: the car jack is not sufficient for this - risk of injury!
•In cases where it be necessary to carry out inspection work when the engine is running there is an additional risk from rotating parts (e.g. the V-

•The spare wheel provided with a car fitted with unidirectional tyres has different dimensions. The wheel is provided with a warning sticker.
•After fitting on the wheel, the warning stic ker must not be concealed (e.g. by the wheel trim).
•Do not drive with this spare wheel at more than 80 km/h - risk of accident. Avoid accelerating at full throttle, sharp braking and fast cornering.
•The inflation pressure for this spare wheel is identical to the inflation pressure of the standard tyres.
•Use this spare wheel only to reach the ne arest specialist garage as it is not intended for co ntinuous use.
Changing a wheel
Preliminary work
The following steps should be carried out before actually changing the
wheel.
– If it is necessary to change a wheel, park the vehicle as far away as
possible from the traffic flow. The place you choose should be level.
– Have all the occupants get out. While changing a wheel, the occu-
pants of the vehicle should not stan d on the road (e.g. behind a crash
barrier).
– Apply the handbrake firmly.
–Engage 1st gear or if your vehicle is fitted with an automatic gearbox,
position the selector lever into position P.
– If a trailer is coupled, uncouple it.
– Take the vehicle tool kit and the spare wheel ⇒page 196 out of the
luggage compartment.
WARNING
•If you find yourself in flowing traffic switch on the hazard warning lights system and place the warning triangle on the side of the road at the prescribed distance from your vehicle while observing all national legal provisions. In this way you are protecting not only yourself but also other road users.
•Never start the engine with the vehicle sitting on the raised jack - danger of suffering injury!
Caution
If you have to change a wheel on a slope first block the opposite wheel with a stone or similar object in order to secure th e vehicle from unexpectedly rolling away.
Note
Comply with the national legal regulations.
Changing a wheel
Always change a wheel on a level surface as far as possible.
– Take off the full wheel trim* ⇒page 198 or the caps ⇒page 199.
– In the case of light alloy wheels remove the wheel trim cap
⇒ page 199.
– Slacken the wheel bolts ⇒page 200.
– Jack up the vehicle until the wheel to be changed is clear of the ground
⇒ page 200.
– Unscrew the wheel bolts and place them on a clean surface (cloth,
paper etc.).
– Take off the wheel.

Connecting positive terminals
– Attach one end to the positive terminal ⇒page 202, fig. 175 of the
discharged battery .
– Attach the other end to the positive terminal of the battery
supplying the power .
Connecting negative term inal and engine block
– Attach one end to the negative terminal of the battery supplying
the power .
– Attach the other end to a solid metal part which is connected
firmly to the engine block, or to the engine block itself ⇒.
Starting engine
– Start the engine of the vehicle providing current and run the engine at
idling speed.
– Now start the engine of the vehicle with the discharged battery.
– Interrupt the attempt at starting an engine after 10 seconds if it does
not start right away and wait for about 30 seconds before repeating
the attempt.
– Disconnect the cables on the engine in exactly the reverse order they
were connected up.
WARNING
•The non-insulated parts of the terminal clamps must never make contact with each other. Furthermore, the cable connected to the positive terminal of the battery must not come into contact with electrically conducting parts of the vehicle - risk of a short circuit!
•Do not affix the jump starting cables to the negative terminal of the discharged battery. There is the risk of detonating gas seeping out the
battery being ignited by the strong spark which results from the engine being started.
•Do not affix the cable end to pa rts of the fuel and brake system.
•Run the jump-start cables so that they cannot be caught by any rotating parts in the engine compartment.
•Do not bend over the batteries - risk of caustic burns!
•The vent screws of the battery cells must be tightened firmly.
•Keep any sources of ignition (naked flame, smouldering cigarettes etc.) away from the battery - risk of an explosion!
Tow-starting and towing vehicle
General
Please pay attention to the following in structions if you are going to use a
tow rope:
Driver of the towing vehicle
– Do not drive off until the tow rope is taught.
– Release the clutch particular ly gently when starting off.
Driver of the towed vehicle
– Switch the ignition on so that th e steering wheel is not blocked and
you can also operate the turn signal lights, the headlight flasher, the
windscreen wipers and windscreen washer system.
– Take the vehicle out of gear or move the selector lever into position N
if your vehicle is fitted with an automatic gearbox.

– Note that the brake servo unit and power steering only operate if the
engine is running. You will require si gnificantly greater physical force
to depress the brake pedal and to steer the vehicle if the engine is not
running.
– Ensure that the tow rope is always kept taught.
Tow rope or tow bar
A tow bar is safest way of towing a vehicle and also minimizes any shocks. You can use a tow rope only if a suitable tow bar is not available.
The tow rope must be elastic to protect the vehicle. Thus one should only use plastic fibre rope or a rope made out of a similarly elastic material.
Attach the tow rope or the tow bar only to the towing eyes provided for this purpose ⇒page 204, “Front towing eye” and ⇒page 205, “Rear towing eye”.
Driving style
Towing another vehicle requires a certain amount of practice. Both drivers should be familiar with the particular points about towing a vehicle. Unskilled drivers should not attempt to tow in another vehicle or to be towed in.
One should be constantly vigilant not to allow impermissibly high towing forces or jerky loadings. There is always a risk of excessive stresses and damage resulting at the points to which you attach the tow ro pe or tow bar when you attempt to tow a vehicle which is not standing on a paved road.
Caution
If the gearbox of your vehicle no longer contains any oil because of a defect, your vehicle must only be towed in with the driven wheels raised clear of the ground, or on a special vehicle transporter or trailer.
Note
•Please comply with any legal requirements particularly regarding the switched on signal systems, when towing in or tow-starting another vehicle.
•The tow rope must not be twisted as it may in certain circumstances result in the front towing eye being unscrewed out of your vehicle.
Front towing eye
The towing eye is stored in the box for the vehicle tool kit.
Installing the towing eye
– Grasp the protective grille at the point marked with the arrow and take
it out ⇒fig. 176.
– Screw in the towing eye by hand to the left up to the stop ⇒fig. 177.
– Tighten up the towing eye using the wheel wrench (push the wheel
wrench through eye).

Removal of the towing eye
– Unscrew the towing eye.
– Put the protective grille in place on the side opposite the marking.
– Press into place the protective grille onto the side facing the marking.
– The protective grille must engage firmly.
Rear towing eye
The rear towing eye is located be low the rear bumper on the right ⇒fig. 178.
Tow-starting a vehicle
If the engine does not start, we generally do not recommend to tow-start
your vehicle. One should attempt to start the engine using jump start
cables ⇒page 202 or call on the services of the SERVICE mobile.
If your vehicle has to be towed:
– Engage 2nd or 3rd gear with the vehicle stationary.
– Depress the clutch pedal fully and keep it depressed.
– Switch on the ignition.
– Wait until both vehicles are movi ng then release the clutch pedal
slowly.
– Depress the clutch pedal fully when the engine fires and take the
vehicle out of gear.
WARNING
There is high risk of having an accide nt when tow-starting a vehicle, when for example the towed vehicle runs into the towing vehicle.
Caution
Vehicles which are fitted with a catalytic converter should not be tow-started over a distance of more than 50 metres. Unburn t fuel may get into the catalytic converter and damage it.
Towing in a vehicle fitted with a manual gearbox
Please refer to the notes ⇒page 203.
The car can be towed in with a tow bar or a tow rope or with the front or rear wheels raised. The maximum towing speed is 50 km/h.
Towing of a vehicle with an automatic gearbox
Please refer to the notes ⇒page 203.
The car can be towed in with a tow bar or a tow rope. Refer at the same time to the following guidelines:
•Move selector lever into N.
•The maximum towing speed is 50 km/h.
