Emission controL
systems
Catalytic converter
Applies to: vehicles with petrol engine
The vehicle must only be used with unleaded pet­

rol,
otherwise the catalytic converter will be ir­
reparably damaged.
Never allow the fuel tank to run completely dry,
as the irregular supply of fuel can cause misfir­

ing.
This allows unburnt fuel to enter the exhaust

system,
which can cause overheating and dam­
age to the catalytic converter.
Diesel particulate filter
Applies to: vehicles with diesel engine
The diesel particulate filter can filter out almost
all soot particles contained in the exhaust gas. In
normal driving conditions the filter is self-clean­

ing.
Should the self-cleaning function of the filter
not be able to operate, e.g. when the vehicle is
continuously used only for short trips, the filter
becomes obstructed with soot and the indicator

A WARNING
The exhaust system is very hot when the
vehi­

cle is being driven and after the engine has
been switched off.
- Never touch the tailpipes when they are hot
- risk of burns!
- Because of the high temperatures which can
occur in the emission controL system, do not
park the vehicle where the exhaust can
come into contact with flammable materials
under the car (e.g. on grass or at the forest
edge) - risk of fire!
- Do not apply any underseal agents in the
area around the exhaust system - risk of

fire!

Engine compartment
Working on components in the engine
compartment
Extra caution is necessary when working on com­
ponents in the engine compartment.
Always be aware of the danger of injury and
scalding as well as the risk of accident or fire
when working in the engine compartment (e.g.
when checking and refilling fluids). Always ob­
serve the warnings listed below and follow all
normal safety precautions. The engine compart­
ment of any motor vehicle is a potentially haz­
ardous area
oA-

A WARNING
- Switch off the engine.
-Switch off the ignition.

-Applythe
parking brake.
- On vehicles with manual gearbox place the
gear lever in neutral, on vehicles with auto­
matic gearbox move the selector lever to
position P.
- To avoid the risk of being scalded, never
open the bonnet if
you
see steam or coolant
escaping from the engine compartment.
Wait until no steam or coolant can be seen
before opening the bonnet.
- Wait for the engine to cool down.
- Keep children away from engine compart­
ment.
- Never spill fluids on a hot engine. These
flu­

ids can cause a fire (e.g. radiator
anti­

freeze).
- Take care not to cause short circuits in the
electrical system.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off - risk of injury!
- Do not unscrew the cap on the expansion
tank when the engine is hot. The cooling
system is under pressure.
- Protect face, hands and arms by covering
the cap with a large, thick rag to protect
against escaping coolant and steam.
295

Checking and topping up fluids
- Never remove the engine cover panel - risk
of burns!
- If any tests have to be performed with the
engine running, there is an extra safety risk
from the rotating parts, such as the drive

belts,
alternator and radiator
fan,
etc., and
from the high-voltage ignition system.
- Never touch the radiator fan. The electric
additional fan is controlled by temperature
and can start running without warning.
- Applies to vehicles with automatic gearbox:
Never open the throttle inadvertently (for
instance by hand from the engine compart­
ment) if
a
gear is engaged while the vehicle
is stationary with the engine running. The
vehicle will otherwise start moving immedi­
ately and could cause an accident.
- Observe the following additional warnings if
work on the fuel system or the electrical
system is necessary:
- Do not smoke.
- Never work near naked flames.
- Always keep an approved fire extinguisher
immediately available.
- Any work on the batteries and electrical sys­
tem in your vehicle entails a risk of injury
and chemical burns in addition to danger of
accident or fire.
For
this reason, you must
have the work carried out by
a
qualified
workshop.
© CAUTION
When topping up fluids make sure the correct
fluid is put into the correct filler opening. This
can otherwise cause serious malfunctions or
engine damage.
® For the sake of the environment
Inspect the ground underneath your vehicle
regularly so that any Leaks are detected at an
early stage. If
you
find spots of oil or other

fluids,
have your vehicle inspected in the
workshop.

Care of vehicle and cleaning
Care of vehicLe and
cleaning
General notes
Regular and careful care helps to maintain the
value of the vehicLe. This may also be one of the
requirements for upholding any warranty claims
in the event of corrosion or paint defects.
Qualified workshops carry stocks of suitable car
care products. PLease
foLLow
the instructions for
use on the packaging.
A WARNING
- Cleaning products and other materials used
for car care can damage health if misused.
- Car care products can contain toxic substan­
ces and must always be kept in a safe place
out of reach of children.

+) For
the sake of the environment
- Please choose care products that are not
harmful to the environment.
- Surplus cleaning materials should not be
disposed of together with ordinary house­
hold waste.
Washing the vehicle
The longer residues like insects, bird droppings,
resinous tree sap or road salt are alLowed to re­
main on the vehicle, the more damage they can
do to the paintwork. High temperatures (for in­
stance in direct sunlight) further intensify the
damage.
Before washing, soak heavy dirt with plenty of
water.
Stubborn dirt, such as bird droppings or resinous
tree sap, is best removed with plenty of water
and a micro-fibre cloth.
After the period when salt is put on the roads,
have the underside of the vehicLe washed thor­
oughly.
High-pressure cleaners
When cleaning the vehicle with a high-pressure
cleaner, always follow the operating instructions
for the equipment. This applies particularly to
the operating pressure and the spraying dis­

tance.
Do not point the spray jet directly at the
seals on the windows, doors, boot lid, bonnet or
panorama sun roof*, or at the tyres, rubber ho­

ses,
insulating material, sensors* or camera
len­

ses*.
Maintain a distance of at least 40 cm.
Do not use a high-pressure cleaner to remove
snow and ice.
Never use high-pressure cleaners with a round-
jet nozzle or "dirt blasters".
The water must not be hotter than 60 °C.
Automatic car washes
Spray the vehicle with water before washing.
Ensure that the windows and panorama sun roof*
are closed and that the windscreen wipers are
switched off. Follow the car wash operator's rules
and recommendations, especially if any accesso­
ries are attached to your vehicle.
If possibLe use a brushless car wash.
Washing by hand
Clean the car with a soft sponge or brush, start­
ing on the roof and working down. Use solvent-
free cleaning agents.
Washing matt-painted vehicles by hand
To avoid damaging the paintwork when washing
the car, first remove any dust, sand and grit. In­

sects,
grease stains and fingerprints are best re­
moved using a special cleaning agent for matt-
painted surfaces.
Apply the product with a micro-fibre cloth. Do
not apply too much pressure to avoid damaging
the paintwork.
Rinse the car thoroughly with water. Then clean
the car with a neutral shampoo and a soft micro-
fibre cloth.
Rinse the car with lots of water again and then
let it dry in the air. Remove any water stains with
a chamois. •
