WARNING■Greater physical effort for braking is required when the engine is switched
off – risk of accident!■
During the braking procedure on a vehicle with manual transmission, when
the vehicle is in gear and at low revs, press the clutch pedal. If you fail to do
so, the functionality of the brake booster can be impaired – risk of accident!
■
If a front spoiler, full wheel trim, etc. is mounted retrospectively, it must be
ensured that the air supply to the front wheel brakes is not reduced. The front
brakes may overheat which can have a negative impact on the functioning of
the braking system - risk of accident!
CAUTION
■ Observe the recommendations on the new brake pads » page 100.■Never let the brakes slip with light pressure on the pedal if braking is not neces-
sary. This causes the brakes to overheat and can also result in a longer braking distance and excessive wear.
Note
■ If the brakes are applied in full and the control unit for the braking system con-
siders the situation to be dangerous for the following traffic, the brake light
flashes automatically. After the speed was reduced below around 10 km/h or the vehicle was stopped, the brake light stops flashing and the hazard warning light
system switches on. The hazard warning light system is switched off automatical-
ly after accelerating or driving off again.■
Before negotiating a steep downhill section, reduce the speed, shift down into
the next lower gear (manual gearbox) or select a lower drive position (automatic
gearbox). As a result, the braking effect of the engine will be used, reducing the
load on the brakes. Any additional braking should be completed intermittently, not continuously.

Apply
›
Pull the handbrake lever firmly upwards.
Loosening
›
Pull the handbrake lever up slightly and at the same time push in the locking
button » Fig. 93 .
›
Move the lever right down while pressing the lock button.
The handbrake warning light
lights up when the handbrake is applied, provided
the ignition is on.
A warning signal sounds if the vehicle is inadvertently driven off with the hand-
brake applied.
The following message is shown in the information cluster display:
Release the parking brake!
or
PARKING BRAKE ON PLEASE RELEASE
The handbrake warning is activated if the vehicle is driven at a speed of more than around 5 km/h for more than 3 seconds.
WARNING■ Please note that the handbrake must be fully released. A handbrake which
is only partially released can result in the rear brakes overheating. This can
have a negative effect on the operation of the brake system - risk of accident!■
Never leave children unattended in the vehicle. The children might, for ex-
ample, release the handbrake or take the vehicle out of gear. The vehicle
might then move off – risk of accident!

Driving and the Environment
Running in
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 maximum speed of the gear in use, i.e. 3/4 of
the maximum permissible engine speed.
›
No full throttle.
›
Avoid high engine speeds.
›
Do not tow a trailer.
From 1 000 up to 1 500 kilometres
Gradually increase the power output of the engine up to the full speed of the
gear engaged, i.e. up to the maximum permissible engine speed.
During the first operating hours the engine has higher internal friction than lateruntil 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.
Never drive at unnecessarily high engine speeds even after the running-in period
is complete. The maximum permissible engine speed is marked by the start of the red scale area of the revolutions counter.
On vehicles fitted with a manual gearbox, at the very latest shift up into the nextgear when the red area is reached. Very high engine speeds when accelerating
(accelerator) are automatically restricted »
.
If the engine is no longer running smoothly, do not drive with unnecessarily low
engine revs on a vehicle with manual transmission. Shift down. Observe the rec-
ommended gear » page 21.
CAUTION■
The engine is not protected from excessive engine revs caused by shifting
down at the wrong time. This can result in the sudden increase in revs beyond
the permissible maximum rpm and thus cause engine damage.■
Never rev up a cold engine when the vehicle is stationary or when driving in in-
dividual gears.
■
All the speed and engine revolution figures apply only when the engine is at its
normal operating temperature.
For the sake of the environment
Never drive with unnecessarily high engine revs. Shifting up sooner helps save on
fuel, reduces engine noises and protects the environment.
New tyres
New tyres have to be “run in” since they do not offer optimal grip at first. Drive
especially carefully for the first 500 km or so.
New brake pads
New brake pads initially do not provide optimal braking performance. They first need to be “run in”. Drive especially carefully for the first 200 km or so.
Catalytic converter
Proper operation of the emission control system (catalytic converter) is of major
significance for driving your vehicle in an environmentally conscious way.
› Vehicles fitted with a petrol engine must always be refuelled with unleaded
petrol » page 168 .
› Do not pour too much oil into the engine
» page 172, Checking the engine oil
level .
› Do not switch off the ignition while you are driving the vehicle.
If you drive your vehicle in a country in which unleaded petrol is not available, you must have the catalytic converter replaced later when driving the vehicle into a
country in which use of a catalytic converter is mandatory.
100Using the system
›If the engine does not start, terminate the attempt to start the engine after
10 seconds and wait for about 30 seconds before repeating the process.›
Disconnect the cables in exactly the reverse order to the one described above.
Jump-starting in vehicles with the START-STOP system
Fig. 168
Engine compartment: Earth
First read and observe the introductory information and safety warn-
ings on page 195.
On vehicles with the START-STOP system, the jump-start cable of the charger
must never be connected directly to the negative pole of the vehicle battery, but
only to the engine earth » Fig. 168.
Towing the vehicle
Introduction
This chapter contains information on the following subjects:
Front towing eye
197
Rear towing eye
197
Vehicles a towing device
198
Vehicles with manual transmission may be towed in with a tow bar or a tow rope
or with the front or rear wheels raised.
Vehicles with automatic transmission may be towed in with a tow bar or a tow
rope or with the front wheels raised. If the vehicle is raised at rear, the automatic
gearbox is damaged!
A tow bar is the safest way of towing a vehicle and also minimises any shocks.
Only use a tow rope if a suitable tow bar is not available.
The following guidelines must be observed.
Driver of the tow vehicle›
Release the clutch particularly gently when starting off or depress the accelera-
tor particularly gently if the vehicle is fitted with an automatic gearbox.
›
On vehicles with a manual transmission, only push down on the accelerator pedal once the rope is taught.
The maximum towing speed is 50 km/h.
Driver of the towed vehicle
›
Switch on the ignition so that the steering wheel is not blocked and so that the
turn signal lights, horn, windscreen wipers and windscreen washer system can be switched on.
›
Take the vehicle out of gear or move the selector lever into position N if the ve-
hicle is fitted with an automatic gearbox.
Please note that the brake servo unit and power steering only operate if the en-
gine is running. If the engine is not running, significantly more physical force is re- quired to depress the brake pedal and steer the vehicle.
If using a tow rope, ensure that it is always kept taught.
CAUTION
■ Do not tow start the engine - danger of damaging the engine! On vehicles with
a catalytic converter, unburnt fuel may get into the catalytic converter where it
may ignite. This in turn may damage or destroy the catalytic converter. The bat-
tery from another vehicle can be used as a jump-start aid » page 195, Jump-start-
ing .■
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.
■
The vehicle must be transported on a special vehicle or trailer if it is not possible
to tow in the vehicle in the way described or if the towing distance is greater than
50 km.
■
To protect both vehicles when tow-starting or towing, the tow rope should be
elastic. Thus one should only use plastic fibre rope or a rope made out of a simi-
larly elastic material.
