Starting-off and Driving
140
WARNING
•When driving, the ignition key mu st always be in the ignition
lock in the position (ignition switched on) without the engine
running. This position is indicate d by the warning lights coming on.
If this is not the case, it could result in unexpected locking of the
steering wheel - risk of accident!
•Only remove the ignition key from the ignition lock when the
vehicle has come to a standstill (put on the handbrake or select the
selector lever position P). The steering lock might otherwise
engage unintentionally - risk of accident!
•Always withdraw the ignition key if you are going to leave the
vehicle, even for a short time. This is particularly important if chil-
dren are left in the vehicle. The children might otherwise start the
engine or switch on electrical equipment (e.g. power windows) -
risk of accident or injury!
Starting engine
General
You can only start the engine only using an original ignition
key.
•Place the gearshift lever into neutral (or place the selector lever to the
position P or N in the case of an automatic gearbox) and put on the hand-
brake firmly before starting the engine.
•The clutch pedal should be fully depressed when starting the engine
which means that the starter only has to crank the engine.
•Let go of the key as soon as the engine starts otherwise there may be
damage to the starter. The engine running noises may at first be louder for a short time after
starting the cold engine until oil pressure can be built up in the hydraulic
valve clearance compensation. This is quite normal and is not an oper-
ating problem.
If the engine does not start ...
You can use the battery of another vehicle as a jump-start aid
⇒page 281.
It is only possible to tow-start vehicles fitted with a manual gearbox. The
tow-starting distance must not be more than 50 metres ⇒page 286.
WARNING
•Never run the engine in non ventilated or enclosed areas. The
exhaust gases of the engine contain besides the odorless and
colourless carbon monoxide a poisonous gas - hazard! Carbon
monoxide can cause unconsciousness and death.
•Never leave your vehicle unattended with the engine running.
Caution
•The starter may only be operated (ignition key position ), if the
engine is not running. If the starter is immediately operated after switching
off the engine, the starter or the engine can be damaged.
•Avoid high engine revolutions, full throttle and high engine loads as
long as the engine has not yet reached its normal operating temperature
- risk of damaging the engine!
•Vehicles which are fitted with an exhaust gas catalytic converter
should not be tow-started over a distance of more than 50 metres.
For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right
away. Through this the engine reaches its operating temperature more
rapidly and the pollutant emissions are lower.

possible (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 with road salt if
you have not used the brakes for some considerable time beforehand.
The layer of salt on the brake discs and brake pads must first be rubbed
off when you apply the brakes.
Corrosion
Corrosion on the brake discs and dirt on the 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 corrosion 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 40,
“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 system could run too hot.
•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 fric-
tion force. You can, however, compensate for this slightly reduced
braking force by increasing the pressure on the brake pedal. This
guideline also applies to any new brake pads installed at a future
date.
Caution
•Never allow the brakes to rub 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, shift down into the next lower gear (manual gearbox) 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 generated when the engine is
running.
WARNING (continued)

New brake pads
Allow for the fact that new brake pads do not achieve their full braking effi-
ciency 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 increasing the pres-
sure 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.
Catalytic converter
Proper operation of the emission control system (catalytic
converter) is of major significance for driving your vehicle
in an environmentally conscious way.
Please refer to the following guidelines:
– For vehicles with petrol engine only refuel with unleaded petrol
⇒page 242, “Grades of petrol”.
– Never run the fuel tank completely empty.
– Do not switch off the ignition while you are driving the vehicle.
– Do not pour too much oil into the engine ⇒page 252, “Replen-
ishing engine oil”. – Do not tow-start the vehicle over a distance of more than 50
metres ⇒page 286, “Tow-starting a vehicle”.
If you drive your vehicle in a country in which unleaded petrol is not avail-
able, you must have the catalytic converter replaced later when driving the
vehicle into a country in which use of a catalytic converter is mandatory.
WARNING
•In view of the high temperatures which may be produced in the
catalytic converter, one should always park a vehicle in such a way
that the catalytic converter cannot come into contact with easily
flammable materials below the vehicle - a risk of fire!
•Never use additional underbody protection or corrosion-protec-
tion agents for the exhaust pipes, catalytic converters or heat
shields. Such substances might ignite when driving - risk of fire!
Caution
•Vehicles fitted with catalytic converter should never be allowed to let
the fuel tank to run completely empty. An irregular fuel supply can result
in poor ignition or misfiring. Unburnt fuel may get into the exhaust system
and damage the catalytic converter.
•Filling the tank even only once with leaded petrol will result in the cata-
lytic converter being destroyed.
•If you detect misfiring, a drop in performance or irregular engine
running when driving, reduce your speed immediately and have the
vehicle inspected by the nearest specialist garage. The symptoms
described may be caused by a fault in the ignition system. Unburnt fuel
may get into the exhaust system and damage the catalytic converter.

Driving and the Environment225
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Sensitive use of the accelerator will not only significantly reduce fuel
consumption but also positively influence environmental pollution and
wear of your vehicle.
You should avoid fully exploiting the top speed of your vehicle wherever
possible. Fuel consumption, pollutant emissions and vehicle noises
increase disproportionally at high speeds.
The
⇒page 224, fig. 184 shows the ratio of fuel consumption to the speed
of your vehicle. You will cut your fuel consumption by half if you only make
use three-quarters of the possible top speed of your vehicle.
Reducing idling
Idling also costs fuel.
It is worthwhile switching off the engine in a traffic jam or when waiting at
a level crossing or at traffic lights with a lengthy red phase. Even after just
30 - 40 seconds you will have saved more fuel than that is needed when
you start the engine up again.
If an engine is only idling it takes much longer for it to reach its normal
operating temperature. Wear-and-tear and pollutant emissions, though,
are particularly high in the warming-up phase. This is why you should
drive off right after starting the engine. Do avoid high engine revolutions
at this time, however.
Regular servicing
A poorly tuned engine consumes an unnecessarily high
amount of fuel.
Having your vehicle serviced regularly at a specialist garge enables you
to satisfy one of the requirements for economical motoring even before
you set off on your journey. Keeping your vehicle properly serviced not
only has a positive effect on the safety of your vehicle and maintaining its
value, but also saves on fuel.
A poorly tuned engine can result in a fuel consumption which is 10%
higher than normal.
The foreseen maintenance work should be undertaken exactly according
to the Service schedule by a specialist garage.
Also check the oil level after refueling. Oil consumption is dependent to
a considerable extent on the load and speed of the engine. Oil consump-
tion could be as high as 0.5 litres/1 000 km depending on your style of
driving.
It is quite normal that a new engine has a higher oil consumption at first,
and reaches its lowest level only after a certain running in time. It is there-
fore not possible to correctly assess the oil consumption of a new vehicle
until after you have driven about 5 000 km.
For the sake of the environment
•You can achieve additional improvements in your fuel economy by
using high-lubricity oils.
•Check the ground below your car at regular intervals to detect any
leakages in good time. Please have your vehicle inspected by a specialist
garge if you find any stains caused by oil or other fluids on the floor.
