Handbrake
Using the handbrake
The handbrake should be applied firmly to prevent the vehi-
cle from accidentally rolling away.
Fig. 148 Handbrake be-
tween the front seats
Always apply the handbrake when you leave your vehicle and when
you park.
Applying the handbrake
– Pull the handbrake lever up firmly ⇒ fig. 148.
Releasing the handbrake
– Pull the lever up slightly and press the release knob in the di-
rection of the arrow ⇒ fig. 148 and guide the handbrake lever
down fully ⇒
. Always apply the handbrake
as far as it will go in order to prevent you from
driving with the handbrake applied by mistake ⇒
.
The handbrake warning lamp lights up when the handbrake is applied
and the ignition switched on. The warning turns off when the handbrake is
released.
If you drive faster than 6 km/h with the handbrake on, the following mes-
sage* will appear on the instrument panel display: HANDBRAKE ON. You will
also hear an acoustic warning signal.
WARNING
● Never use the handbrake to stop the vehicle when it is in motion. The
braking distance is considerably longer, because braking is only applied
to the rear wheels. Risk of accident!
● If it is only partially released, this will cause rear brakes overheating,
which can impair the function of the brake system and could lead to an
accident. This also causes premature wear on the rear brake pads.
CAUTION
Always apply the handbrake before you leave the vehicle. The first gear
should also be selected.
Parking
The handbrake should always be firmly applied when the
vehicle is parked.
Always note the following points when parking the vehicle:
– Use the brake pedal to stop the vehicle.
– Apply the handbrake.
181
Driving
– Select first gear.
– Switch the engine off and remove the key from the ignition. Turn
the steering wheel slightly to engage the steering lock.
– Always take you car keys with you when you leave the vehicle
⇒
.
Additional notes on parking the vehicle on gradients:
Turn the steering wheel so that the vehicle rolls against the kerb if it started
to roll.
● If the vehicle is parked facing downhill, turn the front wheels so that
they point towards the kerb .
● If the vehicle is parked facing uphill, turn the front wheels so that they
point away from the kerb .
● Secure the vehicle as normal by applying the handbrake firmly and se-
lecting first gear.
WARNING
● Take measures to reduce the risk of injury when you leave your vehi-
cle unattended.
● Never park where the hot exhaust system could ignite inflammable
materials, such as dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in the vehicle when it is
locked. They would be unable to open the vehicle from the inside, and
could become trapped in the vehicle in an emergency. In the event of an
emergency, locked doors will delay assistance to occupants.
● Never leave children alone in the vehicle. They could set the vehicle
in motion, for example, by releasing the handbrake or the gear lever.
● Depending on weather conditions, it may become extremely hot or
cold inside the vehicle. This can be fatal.
Hill-start aid*
This function is only included in vehicles with ESC (ESP).
This device helps when starting uphill.
These are the basic operation conditions: doors closed, brake pedal press-
ed down and vehicle in neutral. The system is activated on selecting a gear.
After removing your foot from the brake pedal, the braking force is main-
tained for a few seconds to prevent the vehicle from moving backward when
putting into gear. This short space of time is enough to start the vehicle
with ease.
This system also works when reversing uphill.
WARNING
● If you do not start the vehicle immediately after taking your foot off
the brake pedal, the vehicle may start to roll back under certain condi-
tions. Depress the brake pedal or use the hand brake immediately.
● If the engine stalls, depress the brake pedal or use the hand brake
immediately.
● When following a line of traffic uphill, if you want to prevent the vehi-
cle from rolling back accidentally when starting off, hold the brake pedal
down for a few seconds before starting off.
Note
The Official Service or a specialist workshop can tell you if your vehicle is
equipped with this system.

Parking aid acoustic system*
Rear parking aid
The parking aid system will use an acoustic signal to warn of
the approach of any object towards the rear of the vehicle.
Description
The acoustic parking aid system will measure the distance between the rear
of the vehicle and any possible obstacle using four ultrasonic sensors loca-
ted on the rear bumper. The measuring range of the sensors starts approxi-
mately and depending on the nature of the obstacle at a distance of:
● side of the rear bumper: 0.8 m
● middle of the rear bumper: 1.5 m
Activation
The system is activated by engagement of the reverse gear. A brief acoustic
signal confirms the activation and correct function of the system.
Reverse gear
The distance warning will begin as soon as an obstacle is detected by the
system. The frequency of the bleeps emitted by the system will increase rap-
idly as the vehicle approaches the obstacle.
Within a short distance of about 25 cm, a continuous signal sounds (stop
signal). The driver should not reverse any further.
Trailer towing
For vehicles factory-fitted with a towing bar, the parking aid system will not
be activated by the engagement of the reverse gear when pulling a trailer,
as the trailer's electric connector will be plugged into the vehicle. Possible faults
If a continuous beep sounds for some seconds when the reverse gear is en-
gaged, this indicates that there is a fault in the parking aid system.
If the fault continues until the ignition is turned off, the acoustic signal
warning of the fault will not be emitted every time the system is reactivated
(by engaging the reverse gear). Thus, the system ready indication will not
sound either. Have the fault repaired by an Authorised Service Centre as
soon as possible.
If there is no ready signal or no acoustic warning signal, then the parking
aid loudspeaker is faulty and may not warn of obstacles.
To ensure that the system works properly, the sensors must be kept clean
and free of ice and snow.
WARNING
● The sensors have blind spots in which obstacles may not be detected.
● Always look out for small children and animals because the system
will not always detect them. Always pay attention when reversing to
avoid accidents.
● The parking aid is not a replacement for driver awareness. The driver
must take full responsibility for parking and other manoeuvres.

196Driving and the environment
WARNING (Continued)
● On steep slopes, if brakes are excessively used, they will overheat.
Before driving down a long steep slope, it is advisable to reduce speed
and change down into a lower gear or range (depending on the type of
transmission). This makes use of engine braking and relieves the brakes.
● Never let the brakes “drag” by applying light pressure. Continuous
braking will cause the brakes to overheat and the braking distance will
increase. Apply and then release the brakes alternately.
● Never let the vehicle run with the engine switched off. The braking
distance is increased considerably when the brake servo is not active.
● If the brake fluid loses its viscosity and is subjected to heavy use, va-
pour bubbles can form in the brake system. This reduces the efficiency of
the brakes.
● Non-standard or damaged front spoilers could restrict the airflow to
the brakes and cause them to overheat. Before purchasing accessories
please observe the relevant instructions ⇒ page 214, Technical modifi-
cations.
● If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a specialised workshop immediately and avoid unnecessa-
ry journeys.
Exhaust gas purification system Catalytic converter*
To maintain the useful life of the catalytic converter
– Use only unleaded petrol with petrol engines, as lead damages
the catalytic converter.
– Do not let the fuel get too low in the tank. –
For engine oil changes, do not replenish with too much engine
oil ⇒ page 224, Topping up engine oil .
– Never tow the vehicle to start it, use jump leads if necessary
⇒ page 268.
If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest specialised workshop. In general, the exhaust gas warning lamp
will light up when any of the described symptoms occur ⇒ page 76. If this
happens, unburnt fuel can enter the exhaust system and escape into the en-
vironment. The catalytic converter can also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! There is a risk of
fire.
● Never park where the catalytic converter could come into contact with
dry grass or flammable materials under the vehicle.
● Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter or the heat shields on the exhaust sys-
tem. These materials could catch fire when the vehicle is being driven.
CAUTION
Never run the fuel tank completely dry because the irregularity of the fuel
supply may cause ignition problems. This allows unburnt fuel to enter the
exhaust system, which could cause overheating and damage the catalytic
converter.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust gas under some conditions. This depends
on the sulphur content of the fuel used. Quite often the problem can be
solved by changing to another brand of fuel.

Vehicle maintenance and cleaning
Vehicle maintenance and cleaning General notes
Regular washing and care help maintain the value of your
vehicle.Vehicle maintenance
Regular care and washing help to maintain the value of the vehicle. This
may also be one of the requirements for acknowledging warranty claims in
the event of bodywork corrosion or paint defects.
The best way to protect your vehicle against the harmful effects of the envi-
ronment is through correct maintenance and frequent washing. The longer
substances such as insect remains, bird droppings, resinous tree sap, road
dirt, industrial deposits, tar, soot or road salt and other aggressive materi-
als remain on the vehicle, the more damage they do to the paintwork. High
temperatures (for instance in strong sunlight) further intensify the corrosive
effect.
After winter, a period when salt is put on the roads, it is important to have
the underside of the vehicle washed thoroughly.
Products for vehicle maintenance
Car care products are available in your Authorised Service Centre. Keep the
product instructions until you have used them up.
WARNING
● Car care products can be toxic. Because of this, they must always be
kept closed in their original container. Keep them out of the reach of chil-
dren. Failure to comply could result in poisoning.
● Always read and observe the instructions and warnings on the pack-
age before using vehicle care products. Improper use could cause health
problems or damage the vehicle. The use of certain products may pro-
duce noxious vapours; they should be used in well ventilated areas.
● Never use fuel, turpentine, engine oil, nail varnish remover or other
volatile fluids. These are toxic and highly flammable. Risk of fire and ex-
plosion.
● Before washing your vehicle, or carrying out any maintenance, switch
the engine off, apply the handbrake firmly and remove the key from the
ignition.
CAUTION
Never attempt to remove dirt, mud or dust if the surface of the vehicle is dry.
Never use a dry cloth or sponge for cleaning purposes. This could damage
the paintwork or the windows of your vehicle. Soak dirt, mud or dust with
plenty of water.
For the sake of the environment
● When purchasing products for your vehicle maintenance, select the
ones which are not harmful to the environment.
● The waste from car care products should not be disposed of with ordina-
ry household waste. Observe the disposal information on the package.
