CX) Parking
aids
General notes
Applies to: vehicles with rear parking aid/parking system
plus/park assist
Various systems are available to help you when
parking or manoeuvring in tight spaces, depend­
ing on the equipment fitted on your vehicle.
The rear parking aid gives an acoustic warning if
there are any obstacles behind the car
¢page 104.
When you are parking, the parking system plus
warns you acoustically and optically about obsta­
cles detected in front of and behind the vehicle
¢page 104. On vehicles with park assist, the
area detected at the side of the vehicle ®
¢page 104, Fig. 106 is also monitored.
The reversing camera uses the infotainment sys­
tem display to show a picture of the area behind
the vehicle captured by the camera. Orientation
lines in the image from the reversing camera as­
sist you when parking or manoeuvring
¢ page 106. In addition, you are assisted by the
functions of the parking system plus
¢page 104.
The park assist helps you to find suitable parking
spaces, to manoeuvre the vehicle into spaces par­
allel or perpendicular to the roadside and to drive
out of spaces parallel to the kerb ¢ page 108.
A WARNING
-Always watch the road and the area sur­
rounding the vehicle. The electronic systems
cannot replace the full concentration of the
driver. The driver is always responsible for
safety during parking and all other manoeu­
vres.
- Please note that certain surfaces, such as
clothing fabrics, cannot be detected or dis­
played by the system -risk of accident!
- The sensors and cameras have blind spots in
which neither people nor objects are regis­
tered. It is particularly important to ensure
that there are no small children or animals
near the vehicle -risk of accident! Parking
aids
- Impacts or damage to the radiator grille,
bumper, wheel arches or underbody can
cause misalignment of the sensors. This can
impair the effectiveness of the parking aids.
Have the systems checked by a qualified
workshop.
CD CAUTION
- The system may not always be able to de­
tect objects such as the following:
- Chains, trailer draw bars, posts or fences
- Objects above the sensors, such as wall
protrusions, etc.
- Objects with certain surfaces or struc­
tures, such as wire fences or powder snow
- As your car moves closer to low obstacles,
they may disappear from the sensors' field
of vision. Please note that you will no longer
be warned about these obstacles.
- Remember to maintain sufficient clearance
from the kerb to avoid damaging the wheel
rims.
(@ Note
- In certain situations, a warning may be giv­
en by the system even if there is no obstacle
within range of the sensors. This can be
caused by the following, for instance:
- Certain road surfaces or long grass
- External ultrasound sources, e.g. from
street cleaning vehicles
- Heavy rain or snow or dense exhaust
fumes
- To familiarise yourself with the system, we
recommend that you practise parking in a
quiet location or a car park. The weather
and light conditions should be good.
- You can adjust the volume of the beeps.
- There is a slight delay in the picture display.
- To ensure that the acoustic parking aid
works properly, the sensors must be kept
clean and free of snow and ice.

CX) consumed,
but only a small amount is supplied.
The situation is also critical if electrical equip­
ment is in use when the engine is not running. In
this case power is consumed when none is being
generated.
In these situations you will be aware that the
power management system is intervening to con­
trol the distribution of electrical power.
When the vehicle is parked for long periods
If you do not drive your vehicle for a period of
several days or weeks, the power management
will gradually shut off the on-board systems one
by one, or reduce the amount of current they are
using. This limits the amount of power consumed
and helps to ensure reliable starting even after a
long period. Certain convenience features, such
as remote control unlocking, may not be availa­
ble. These functions will be restored when you
switch on the ignition and start the engine.
With the engine switched off
If you listen to the radio or use the other info­
tainment functions when the engine is not run­
ning, this will discharge the vehicle battery.
The infotainment display will show a warning
message before the battery power drops to a lev­
el where the starting ability is impaired. This
message warns you that the system you are using
will soon be switched off automatically. You
should therefore start the engine if you wish to
continue using the system.
When the engine is running
Although the alternator generates electrical
power, the vehicle battery can still become dis­
charged while the vehicle is being driven. This can
occur when a lot of power is being consumed but
only a small amount supplied, especially if the
vehicle battery is not fully charged initially.
To restore the necessary energy balance, the sys­
tem will then temporarily shut off the electrical
components that are using a lot of power, or re­
duce the current they are consuming. Heating
systems in particular use a large amount of elec­
trical power. If you notice, for instance, that the
seat heating* or the rear window heater is not Intelligent
technology
working, they may have been temporarily switch­
ed off or regulated to a lower heat output. These
systems will be available again as soon as suffi­
cient electrical power is available.
You may also notice that the engine runs at a
slightly faster idling speed. This is quite normal,
and no cause for concern. The increased idling
speed allows the alternator to meet the greater
power requirement and charge the vehicle bat­
tery at the same time.
Information saved in the
control units
The vehicle is fitted in the factory with electronic
control units that, among other things, control
the engine and the gearbox. The control units al­
so monitor the exhaust system and the airbags.
The control units continually analyse data rele­
vant to the vehicle while you are driving. In the
event of faults or anomalies in the vehicle data,
only these data are saved. As a rule, faults are
shown by the warning lamps in the instrument
cluster.
Data saved in the control units can only be read
and analysed with special equipment.
A qualified workshop is only able to recognise
and deal with faults by using the relevant saved
data. Among other things, the saved data may
contain the following information:
- Data relating to the engine and the gearbox
-Speed
- Direction of travel
- Braking force
- Seat belt warning system data
The control units installed will not under any cir­
cumstances record conversations in the vehicle.
Event data recorder
Your vehicle is not equipped with an event data
recorder.
In an event data recorder, information about
the
vehicle is temporarily saved. In the event of an
accident, you can therefore obtain detailed infor-
mation about the course of events. On vehicles ...,.

CX) the
canister during filling. This helps
prevent an electrostatic charge building
up.
- Make sure you never spill fuel in the vehi­
cle or in the luggage compartment. Fuel
vapour is explosive -danger to life!
CD CAUTION
- If any fuel is spilt onto the vehicle, it should
be removed immediately as it could other­
wise damage the paintwork.
- Never run the tank completely dry. If there
is an irregular fuel supply, misfiring can oc­
cur. As a result unburnt fuel can enter the
exhaust system and cause damage to the
catalytic converter(s).
- When filling the fuel tank after having run it
completely dry on a vehicle with a diesel en­
gine the ignition must be switched on for at
least 30 seconds without starting the en­
gine. When you then start the engine it may
take longer than normal (up to one minute)
for the engine to start firing. This is because
air needs to be bled from the fuel system
while starting.
@) For the sake of the environment
Do not try to put in more fuel after the auto­
matic filler nozzle has switched off; this may
cause the fuel to overflow if it becomes warm.
@ Note
Should the fuel tank flap become frozen stuck
during inclement weather, press the middle
of the flap with the palm of the hand and try
again.
(ill) Note
- To prevent the tank from being filled with
the incorrect type of fuel, only suitable filler
nozzles can be inserted in the fuel filler on
your vehicle.
- If the filler nozzle is old, damaged or too
small, it may not be able to open the pro­
tection mechanism on the fuel tank. In this
case, try turning the filler nozzle before in­
serting it in the fuel filler neck, use a differ- Checking

ent filling pump or seek professional assis­
tance.
- The protection mechanism will not open if
you try to add fuel from a spare fuel canis­
ter. If you need to fill the tank from a spare
fuel canister, you must use the special fun­
nel stowed in the luggage compartment

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-
244 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 symbol
C for the diesel particulate filter lights up
¢page 17.
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 ¢ A .
A WARNING
- Switch off the engine.
- Switch off the ignition.
- Apply the parking brake.
- Put the gear lever in neutral or selector in P.
- Wait for the engine to cool down.
- Keep children away from engine compart-
ment.

Downloaded from www.Manualslib.com manuals search engine Checking
and topping up fluids
- Switch off the warm engine. Wait for a few mi­
nutes for the oil to drain back into the sump.
- Open the bonnet ¢page 245.
- Pull out the oil dipstick ¢page 246, Fig. 214,
wipe it with a clean cloth and insert it again,
pushing it in as far as it will go.
- Then pull the dipstick out again and check the
oil level ¢table on page 248.
- If the oil level is too low, add more engine oil.

@ When
the oil Level is near the marking @
you must top up the engine oil. Please refer
to ¢ 0.
@ Do NOT add engine oil.
®
@ Do
NOT add engine oil.
Drive to a qualified workshop without delay
and have the engine oil changed ¢0.
Topping up the engine oil
- Unscrew the cap "E::71 ¢Fig. 216from the oil fill­
er opening ¢ page 246, Fig. 214.
- Carefully add 0.5 litres of suitable engine oil
¢page 247.
-After two minutes check the oil level once
again.
- If the oil level is too low, add a smaller quantity
of engine oil. The level must always be below
the marking @¢Fig. 215 ¢0.
- Screw the oil filler cap "E::71 back on and push
the dipstick all the way in.
A WARNING
- Ensure that no engine oil comes into contact
with hot engine components when topping
up: this could cause a fire.
- The oil filler cap must be properly closed to
prevent oil from squirting onto the hot en­
gine or exhaust system while the engine is
running -risk of fire!
- Wash your skin thoroughly if it comes into
contact with engine oil.
248 CD
CAUTION
- The engine oil must never drop below the
marking (!)¢ Fig. 215 -risk of engine dam­
age!
- When topping up the engine oil, make sure
that the oil level is not above the marking
@ ¢Fig. 215, as this may result in damage
to the catalytic converter or to the engine.
Do NOT start the engine. Contact a qualified
workshop to extract the engine oil if neces­
sary.
- Applies to vehicles which have an oil dip­
stick with area® ¢Fig. 215: If you run your
vehicle on diesel fuel of poorer quality than
EN 590 standard fuel, the fuel can get into
the engine oil. In this case, the oil Level
gradually rises and the quality of the engine
oil decreases. Once the oil level has reached
the marking @or the indicator lamp II
has come on, the engine oil level must not
be corrected by extracting the surplus oil -
risk of engine damage! The engine oil must
be changed ¢ page 18.
- No additives should be used with engine oil.
Any damage caused by the use of such addi­
tives would not be covered by the factory
warranty.
® For the sake of the environment
- Never pour engine oil down drains or into
the ground.
-Always observe statutory requirements
when disposing of empty oil canisters.
@ Note
Depending on how you drive and the condi­
tions in which the car is used, oil consumption
can be up to 0.5 Ltr./1000 km. Oil consump­
tion on RS models can be up to 0.8 ltr./1,000
km. Oil consumption is likely to be higher for
the first 5,000 km. For this reason the engine
oil level must be checked at regular intervals,
preferably when filling the tank and before a
journey.
