Front parking aid
The parking aid system will sound an audible warning to in-
dicate of the approach of any object towards the front or
rear of the vehicle.
Description
The acoustic parking aid system measures the distance between the vehicle
and any possible obstacle using 8 ultrasonic sensors (4 of which are loca-
ted on the rear bumper and 4 of which are located on the front bumper).
The measuring range of the sensors starts approximately and depending on
the nature of the obstacle at a distance of:
● side of the front bumper: 0.6 m
● middle of the front bumper: 1.2 m
● side of the rear bumper: 0.6 m
● middle of the rear bumper: 1.6 m
Activation
The system may be activated in the following ways:
● Engage the reverse gear (a brief, sharp acoustic signal confirms activa-
tion and the correct operation of the system) or
● Push the central console button (a brief confirmation signal will
sound and the button’s LED will light up).
Disconnection
The system may be deactivated in the following ways:
● Drive forwards at more than approx. 10 km/h (6 mph) or else
● Press the button, or
● Switch the ignition off Manoeuvres
The distance warning will begin as soon as an obstacle is detected in the
system's field of detection (front and rear). The frequency of the bleeps
emitted by the system will increase rapidly as the vehicle approaches the
obstacle. Two speakers, one in the front and one in the rear, indicate the lo-
cation of the obstacle (either front or rear).
After a distance lower than approximately 30 cm, a continuous signal
sounds (stop signal). At this point the driver should halt the vehicle.
Models with a factory-fitted towing bracket: When the vehicle is less than
0.35 m away from the obstacle the warning tone will sound continuously.
The driver should then not reverse any further.
The warning tone volume decreases by 30% 3 seconds after it is triggered if
the detected obstacle stays at a constant distance from the vehicle.
Provided that it is not in continuous mode, the tone on the parking aid sys-
tem stops when it detects a wall parallel to the vehicle.
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, sharp beep sounds for various seconds, there is a fault in
the parking aid system.
If the fault continues until the ignition is turned off, the audible warning of
the fault will not be emitted every time the system is reactivated (by engag-
ing the reverse gear or pressing the button). Thus, the system ready indi-
cation will not sound either. Have the fault repaired by a Technical Service
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

Cruise speed* (Cruise control system)
Description
The CCS is able to maintain the set speed in the range from
approx. 30 km/h (19 mph) to 180 km/h (112 mph). Once the speed setting has been saved, you may take your foot off the ac-
celerator.
WARNING
It could be dangerous to use the cruise control system if it is not possible
to drive at constant speed.
● Do not use the cruise control system when driving in dense traffic, on
roads with lots of bends or on roads with poor conditions (with ice, slip-
pery surfaces, loose grit or gravel), as this could cause an accident.
● Always switch the cruise control system off after using it in order to
avoid involuntary use.
● It is dangerous to use a set speed which is too high for the current
road, traffic or weather conditions. Risk of accident.
Note
The cruise control cannot maintain a constant speed when descending
downhill. The vehicle will accelerate due to its own weight. Use the foot
brake to slow the vehicle. Switching the cruise control system on and off

Driving and the environment
WARNING
The catalytic converter reaches very high temperatures! 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. Diesel engine particulate filter*
The diesel particulate filter eliminates soot produced by
burning diesel.
Fig. 128 Vehicle data
sticker on back cover of
the Maintenance Pro-
gramme
Your vehicle is fitted with a DPF (Diesel particulate filter) if the vehicle data
sticker (back cover of the “Maintenance Programme”) lists the PR code 7GG
or 7MG ⇒ Fig. 128.
The diesel engine particulate filter eliminates most of the soot from the ex-
haust gas system. Under normal driving conditions, the filter cleans itself. If
driving conditions do not allow the filter to clean itself (for example, multi-
ple short trips) the filter will be obstructed by dust and pollen and the diesel
engine particulate filter warning lamp will light up. This does not repre-
sent a fault, it is a warning that indicates that the filter has not been able to
regenerate automatically and that you must carry out a cleaning cycle, as in-
dicated in ⇒ page 70.

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 Technical Services. 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 car-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.

Vehicle maintenance and cleaning
WARNING
● Wash your vehicle with the ignition switched off.
● Protect your hands and arms from cuts on sharp metal edges when
cleaning the underbody, the inside of the wheel housings etc. Risk of in-
jury.
● Water, ice and salt on the brake system can reduce braking effective-
ness. Risk of accident.
CAUTION
● Never remove dirt, mud or dust if the vehicle surface is dry. Never use a
dry cloth or sponge for cleaning purposes. This could scratch the paintwork
or glass on your vehicle.
● Washing the vehicle in low temperatures: when washing the vehicle
with a hose, do not direct water into the lock cylinders or the gaps around
the doors, rear lid, or sunroof. Risk of freezing.
For the sake of the environment
To protect environment, the vehicle should be washed only in specially pro-
vided wash bays. This prevents toxic, oil-laden waste water entering the
sewerage system. In some places, washing vehicles outside wash bays is
prohibited.
Note
Do not wash the vehicle in direct sunlight. Washing the vehicle with a high pressure cleaner
Be particularly careful when using a high pressure cleaner!
– Always observe the instructions for the high-pressure cleaner,
particularly those concerning the pressure and the spraying
distance.
– Increase the spraying distance for soft materials and painted
bumpers.
– Do not use a high pressure cleaner to remove ice or snow from
windows ⇒ page 190.
– Never use concentrated jet nozzles (“rotating jets”) ⇒
.
– After washing, avoid sudden and sharp braking. “Dry” the
brakes by braking several times ⇒ page 179.
WARNING
● Never wash tyres with a concentrated jet (“rotating nozzle”). Even at
large spraying distances and short cleaning times, visible and invisible
damage can occur to the tyres. This may cause an accident.
● Water, ice and salt on the brake system can reduce braking effective-
ness. Risk of accident.
CAUTION
● Do not use water hotter than +60 °C (+140 °F). This could damage the
vehicle.
● To avoid damage to the vehicle, keep a sufficient distance from sensitive
materials such as flexible hoses, plastic, soundproofing material, etc. This
is also important for bumpers painted in the colour of the bodywork. The
closer the nozzle is to the surface, the greater the wear on the material.

Vehicle maintenance and cleaning
WARNING
Do not apply underseal or anti-corrosion coatings to the exhaust pipes,
catalytic converter or the heat shields on the exhaust system. The heat of
the exhaust system or the engine could cause them to ignite. Risk of fire.
Cleaning the engine compartment
Take special care when cleaning the engine compartment.
Anti-corrosion treatment
The engine compartment and the surface of the power unit are given anti-
corrosion treatment at the factory.
Good corrosion protection is particularly important in winter when the vehi-
cle is frequently driven on salted roads. To prevent the salt corroding the ve-
hicle, the entire engine compartment should be thoroughly cleaned before
and after winter.
Your Technical Services have got the necessary workshop equipment to pro-
vide the correct cleaning and preserving products. For this reason, we rec-
ommend having this work performed by them.
The anti-corrosion protection is usually removed if the engine compartment
is cleaned with grease removing solutions, or if you have the engine
cleaned. On commissioning this work, ensure that all surfaces, seams,
joints and components in the engine compartment are given anti-corrosion
treatment.
WARNING
● When working in the engine compartment, always observe the safety
warnings ⇒ page 206.
● Before opening the bonnet, switch the engine off, apply the hand-
brake firmly and always remove the key from the ignition.
● Allow the engine to cool before you clean the engine compartment.
● Do not clean the vehicle underbody, wheel arches or wheel trims
without protecting your hands and arms. You may cut yourself on sharp-
edged metal parts. Failure to comply could result in injury.
● Moisture, ice and salt on the brake system may affect braking effec-
tiveness. Risk of accident. Directly after washing, avoid sudden and
sharp braking.
● Never touch the radiator fan. It is temperature-controlled and could
start automatically, even when the key is removed from the ignition!
For the sake of the environment
Fuel, grease and oil deposits could be removed when the engine is washed.
The polluted water must be cleaned in an oil separator. For this reason, en-
gine washing should be carried out only by a specialised workshop or a pet-
rol station.
Vehicle interior maintenance Plastic parts and dash panel cleaning
– Use a clean, damp cloth to clean plastic parts and the dash
panel.
– If this does not provide satisfactory results, use a special sol-
vent-free plastic cleaning product.

Checking and refilling levels
WARNING
● Fuel is highly flammable and can cause serious burns and other inju-
ries.
–Never smoke or use an open flame when filling the fuel tank of the
vehicle, or a spare fuel canister, with fuel. This is an explosion haz-
ard.
– Follow legal requirements for the use of spare fuel canisters.
– For safety reasons we do not recommend carrying a spare fuel can-
ister in the vehicle. The canister could be damaged in an accident and
leak.
● If, in exceptional circumstances, you have to carry a spare fuel canis-
ter, please observe the following points:
–Never fill the spare fuel canister inside the vehicle or on it. An elec-
trostatic charge could build up during filling, causing the fuel fumes
to ignite. This could cause an explosion. Always place the canister on
the ground to fill it.
– Insert the fuel nozzle into the mouth of the canister as far as possi-
ble.
– If the spare fuel canister is made of metal, the filling nozzle must
be in contact with the canister during filling. This helps prevent an
electrostatic charge building up.
– Never spill fuel in the vehicle or in the luggage compartment. Fuel
vapours are explosive. Danger of death.
CAUTION
● Fuel spills should be removed from the paintwork immediately.
● Never run the tank completely dry. An irregular fuel supply could cause
misfiring. As a result, unburnt fuel could enter the catalytic converter and
cause damage.
● 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 sec-
onds 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 due to the fact that the fuel system has to purge itself of air before
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.
