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!

CX) Cooling
system
Coolant
The engine cooling system is filled at the factory
with a mixture of conditioned water and coolant
additive. This coolant must not be changed.
The coolant level is monitored by a warning lamp
• ¢page 14. However, we recommend that it
should be checked occasionally.
If you do need to top up the coolant, use a mix­
ture of water and coolant additive. We recom­
mend mixing coolant additive with distilled wa­
ter.
Coolant additive
The coolant additive contains anti-freeze and cor­
rosion protection agent. Only use one of the fol­
lowing coolant additives. It is possible to mix
these additives.
Coolant additive Specification
G13 TL 774
J
G12++ TL 774 G
The amount of coolant additive which needs to
be mixed with the water depends on the temper­
atures to be expected in the winter season. If the
anti-freeze concentration is too low, the coolant
can freeze and cause engine damage.

CD CAUTION
- Have your qualified workshop check the
cooling system before the winter season to
make sure that the anti-freeze concentra­
tion is adequate for the conditions to be ex­
pected. This applies particularly if you drive
into a colder climate zone.
- To prevent damage to the engine, do not
use a different type of anti-freeze additive if

CX) Explanation
of warnings on vehicle battery:
® Wear safety
glasses!
A Battery
acid is extremely corrosive. Wear
protective gloves and safety glasses.
@ Keep
open flames, sparks, uncovered
Lights and Lit cigarettes away from the
battery!
� A
highly explosive mixture of gases may
be given off when the battery is under
charge!
® Keep children
away from batteries and
battery acid.
.&_ WARNING
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 acci­
dent or fire. For this reason, you must have
the work carried out by a qualified workshop.
CD CAUTION
If the car is left standing for Long periods,
protect the battery from frost. The battery
will be damaged irreparably if it is allowed to
freeze <=> page 2 51.
@ For the sake of the environment
'8 Batteries contain toxic substances including
sulphuric acid and Lead. Please contact a
qualified workshop if you have any questions.
Vehicle battery
The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
If the vehicle is not used 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 <=> page 118. Certain convenience fea­
tures, such as interior Lighting or electric seat ad­
justment, may not be available. These functions Checking
and topping up fluids
will be restored when you switch on the ignition
and start the engine.
Even though some systems are deactivated auto­
matically, certain electrical equipment continues
to draw current even when the ignition is off. If
the vehicle is Left standing for Long periods, this
can result in total battery discharge. If the vehi­
cle battery is allowed to discharge completely, an
internal chemical reaction damages the battery
irreparably. To avoid this, the vehicle battery
should be recharged at Least once a month
<=> page 251. Please contact a qualified workshop
if you have any questions.
Winter conditions
Cold weather is very hard on the vehicle battery.
The starting capacity may be reduced as a result.
For this reason, you should have the vehicle bat­
tery checked by a qualified workshop before the
start of winter.
Charging the vehicle battery

On tyres with a directional tread pattern, note
the direction of rotation indicated on the sidewall
¢page 275.
Concealed damage
Damage to tyres and rims is often not readily visi­
ble. If you notice unusual vibrations or the car
pulling to one side, this may indicate that one of
the tyres is damaged. Reduce your speed imme­
diately. Inspect the tyres for damage. If no exter­
nal damage is visible, drive slowly and carefully
to the nearest qualified workshop and have the
car inspected.
A WARNING
Insufficient tread depth or different tread
depths on different wheels reduce safety. This
is particularly evident in vehicle handling,
when there is a risk of aquaplaning in deep
puddles of water and when driving through
corners. Braking is also adversely affected -
risk of accident!

load, you must increase the tyre pressure to the
specified maximum@ ¢&_.
Checking / adjusting the tyre pressures
"' Check the tyre pressures at least once a month
and, in addition, before starting a long journey.
.. The tyre pressures should only be checked
when the tyres are cold. The slightly raised
pressures of warm tyres must not be reduced.
.. Refer to the sticker ¢ Fig. 222 for the correct
tyre pressures according to the load the vehicle
is carrying.
.. If necessary, adjust the tyre pressure.
.. Vehicles with tyre pressure loss indicator* or
tyre pressure monitoring system*: Store the
new tyre pressures in the infotainment system
¢page 259.
"' Check the pressure of the spare wheel* /com­
pact temporary spare wheel*. Keep the spare
tyre inflated to the highest pressure approved
for the tyre.
A WARNING
Always adjust the tyre pressures to match
your driving style and the load the vehicle is
carrying.
- Excessive loads can cause you to lose control
of the vehicle -risk of accident!
- Under-inflated tyres flex more and can over­
heat at high speeds or when the vehicle is
carrying a heavy load. This could cause a
tyre blow-out and you could lose control of
the vehicle -risk of accident!
- Incorrect tyre pressures increase tyre wear
and adversely affect vehicle braking and
handling -risk of accident!
CD CAUTION

immediately.
A WARNING
Please observe the important safety informa­
tion and notes ¢page 260. Wheels
Storing new tyre pressures
Applies to: vehicles with tyre pressure monitoring system
To enable the tyre pressure monitoring system
to work reliably, it is important to store the cor­
rect pressure settings.
You should always store the tyre pressures if new
sensors are fitted or after changing the pressures
when carrying a different amount of passengers
or luggage.
... Before storing the new tyre pressures, check
that the current pressures on all four wheels
correspond to the specified values and adapt
the pressures to the current load ¢ page 256,
Fig. 222. Only adjust and store the inflation
pressure of the tyres when they are at approxi­
mately ambient temperature. If the tyre tem­
peratures are higher than the ambient temper­
ature, the inflation pressures should be in­
creased by approx. 0.2 bar above the pressures
specified on the tyre pressure sticker.
... Switch on the ignition.
... Select the following on the infotainment sys­
tem: I MENU I button > Servicing & checks >
Tyre pressure loss indicator > Store tyre pres­
sures > Yes, store now. The tyre pressure moni­
toring system will then measure the current
tyre pressures when you drive the vehicle and
store them as the new reference values .
... If the new tyre pressures do not appear on the
infotainment display, you will need to drive for
about 10 minutes so that the sensor signal
from the wheels can be received again .
During this initialisation phase,--.--will be
shown on the pressure and temperature display
and some functions of the tyre pressure monitor­
ing system will not be available. The system will
warn you only if the pressure of one or more tyres
is below the minimum reference pressure.
If the indicator lamp RE lights up and the mes­
sage Tyre pressure: wheel change detected.
Please check all tyres and store pressures in

CX) 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 materials. 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 are allowed to remain on the
vehicle, the more damage they can do to the
paintwork. High temperatures (for instance in di­
rect 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 Care
of vehicle and cleaning
the operating pressure and the spraying dis­
tance. Do not point the spray jet directly at the
seals on the windows, doors, bonnet or boot lid,
or at the tyres, rubber hoses, insulating material,
sensors* or camera lenses*. 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 are closed and that the
windscreen wipers are switched off. Follow the
car wash operator's rules and recommendations,
especially if any accessories are attached to your
vehicle.
If possible use a brush less 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.
