Use as uitabl et ouch-up stick, e.g. MB Touch-
Up Stick ,tor epair slight damage to the paint-
work quickly and provisionally.
Matt ef inish care
! Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to shine.
! The following may cause the paint to
become shiny and thus reduce the matte
effect: R
strong rubbing of the paintwork with
unsuitabl em aterialsR
frequent use of automatic car washes R
washing the vehicle in direct sunlight
! Never use paint cleaner, buffing or polishing
products, or gloss preserver, e.g. wax, for the
purpose of paintwork care. These products
are only suitabl ef or high-gloss surfaces. Their
use on vehicles with matte paintwork leads to
considerable surface damage or, more spe-
cifically ,tos hiny, spotted areas.
Alway sh ave paintwork repairs carried out at a
qualified specialist workshop.
! Do not use wash programs with ah ot wax
treatment under any circumstances.
Observe these notes if your vehicle has ac lear
matte finish. This will help you to avoid damage
to the paintwork due to incorrect treatment.
These notes also apply to light alloy wheels with
ac lear matte finish.
The vehicle should ideally be washed by hand
using as oft sponge, car shampoo and plenty of
water.
Use only insect remover and car shampoo from
the range of approved Mercedes-Benz care
products.
Cleaning the vehicl ep arts
Cleaning the wheels
G WARNING
The water jet from ac ircular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nent sd amage dint his way may fail unexpect-
edly .T here is ar isk of an accident. Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis component sr eplaced imme-
diately.
! Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park your vehicle for al ong period of
time directly after cleaning, particularl ya fter
cleaning the wheel rim with wheel cleaner.
Wheel cleaner can lead to the increased cor-
rosion of the brake discs and pads. Therefore,
drive for af ew minutes after cleaning. By
heating up the brakes, the brake discs and
pads dry. The vehicle can then be parked for a
long period of time.
Cleaning the windows
G WARNING
You could become trapped by the windshield
wipers if they start moving while cleaning the
windshiel dorw iper blades. There is ar isk of
injury.
Alway ss witch off the windshiel dw ipers and
the ignition before cleaning the windshiel do r
wiper blades.
! Only fold the windshiel dw ipers awa yf rom
the windshiel dw hen vertical. Otherwise, you
will damage the hood.
! Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the inside of the windows. Do
not touch the insides of the windows with
hard objects, e.g. an ice scraper or ring. There
is otherwise ar isk of damaging the windows.
! Clea nt he water drainage channels of the
windshiel da nd the rear window at regular
intervals. Deposits such as leaves, petals and
pollen may under certain circumstances pre-
vent water from draining away. This can lead
to corrosion damage and damage to elec-
tronic components. X
Clea nt he inside and outside of the windows

PSI (pounds per squar ei nch)As tandard unit of measure for tire pressure.
Aspect ratio Relationship between tire height and tire width
in percent.
Tire pressure This is pressure inside the tire applying an out-
ward force to each square inch of the tire's sur-
face. The tire pressure is specified in pounds per
square inch (psi), in kilopascal (kPa) or in bar.
The tire pressure should only be corrected when
the tires are cold.
Cold tire pressure The tires are cold: R
if the vehicle has been parked with the tires
out of direct sunlight for at least three hours
and R
if the vehicle has not been driven further than
1m ile (1.6 km)
Tread The part of the tire that comes into contact with
the road.
Bead The tire bead ensures that the tire sits securely
on the wheel. There are several steel wires in the
bead to prevent the tire from coming loose from
the wheel rim.
Sidewall The part of the tire between the tread and the
bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 2.3 kg (5 lbs). These
optional extras, such as high-performance
brakes, level control, ar oof rack or ah igh-per-
formanc eb attery, are not included in the curb
weight and the weight of the accessories.
TIN (Tire Identification Number)
This is au nique identifier which can be used by
at ire manufacturer to identify tires, for example
for ap roduct recall, and thus identify the pur-
chasers. The TIN is made up of the manufactur-
er's identity code, tire size, tire type code and
the manufacturing date. Load bearing index The load bearing index (also load index) is ac ode
that contains the maximum load bearing capa-
city of at ire.
Traction Traction is the result of friction between the tires
and the road surface.
Treadwear indicators Narrow bars (tread wear bars) that are distrib-
uted over the tire tread. If the tire tread is level
with the bars, the wear limit of

Brake fluid
G WARNING
The brake flui dc onstantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
flui dist oo low ,v apo rp ockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is ar isk of an accident.
You should have the brake flui dr enewe da t
the specified intervals.
When handling brake fluid, observe the impor-
tant safety notes on service products
( Y
pag e3 15).
The brake flui dc hange interval sc an be found in
the Maintenance Booklet.
Only use brake flui da pproved by Mercedes-
Benz in accordance with MB-Freigabe or MB-
Approva l3 31.0.
Information about approved brake flui dc an be
obtained at any qualified specialist workshop or
on the Internet at
http://bevo.mercedes-benz.com. i Have the brake flui dr egularl yr eplaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Coolant
Important safety notes
G WARNING
If antifreeze comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is ar isk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clea nt he
antifreeze from components before starting
the engine.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
coul do therwise damage the engine.
Further information on coolants can be found
in the Mercedes-Benz Specifications for Ser-
vice Products, MB BeVo 310.1, e.g. on the
Internet at http://bevo.mercedes-benz.com.
Or contact aq ualified specialist workshop.
! Always use as uitable coolant mixture, even
in countries where high temperatures prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosio na nd
overheating.
i Have the coolant regularl yr eplaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Comply with the important safety precautions
for service products when handling coolant
( Y
pag e3 15).
The coolant is am ixture of water and corrosion
inhibitor/antifreeze concentrate. It performs
the following tasks: R
Anti-corrosion protection R
Antifreeze protection R
Raising the boiling point
If the coolant has antifreeze protection down to
-35 ‡( -37 †), the boiling point of the coolant
during operation is approximatel y2 66 ‡
(130 †).318
