Information about Service
Resetting the service display
!Have service work carried out as descri-
bed in the Maintenance Booklet. This may
otherwise lead to increased wear and dam-
age to the major assemblies or the vehicle.
A qualified specialist workshop, e.g. a smart center, will reset the service interval dis-
play after the service work has been carried
out. You can also obtain further information
on maintenance work, for example.
Special service requirements
The prescribed service interval is based on
normal operation of the vehicle. Service work
will need to be performed more often if the
vehicle is operated under arduous conditions
or increased loads, for example:
Rregular city driving with frequent inter-
mediate stops
Rif the vehicle is primarily used to travel
short distances
Rfor frequent operation in mountainous ter-
rain or on poor road surfaces
Rif the engine is often left idling for long
periods
In these or similar operating conditions,
have, for example, the air filter, engine oil
and oil filter changed more frequently. The
tires must be checked more frequently if the
vehicle is operated under increased loads.
You can obtain further information at a
qualified specialist workshop, e.g. a smart
center.
Driving abroad
An extensive smart service network is also
available in other countries. For further
information inquire at any smart center.
Care
General notes
HEnvironmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible
manner.
154Care
>> Maintenance and care.

!For cleaning your vehicle, do not use any
of the following:
Rdry, rough or hard cloths
Rabrasive cleaning agents
Rsolvents
Rcleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film.
!Do not park the vehicle for an extended
period straight after cleaning it, partic-
ularly after having cleaned the wheels with
wheel cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked.
Regular care of your vehicle is a condition
for retaining the quality in the long term.
Use care products and cleaning agents rec-
ommended and approved by smart.
Exterior care
Automatic car wash
GWARNING
Braking efficiency is reduced after wash-
ing the vehicle. There is a risk of an acci-
dent.
After the vehicle has been washed, brake
carefully while paying attention to the
traffic conditions until full braking power
is restored.
!Never clean your vehicle in a Touchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
!Make sure that:
Rthe side windows are fully closed
Rthe climate control blower is switched
off
Rthe windshield wiper switch is at posi-
tion 0
The vehicle may otherwise be damaged.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it
before cleaning it in an automatic car wash.
After using an automatic car wash, wipe off
wax from the windshield and the wiper blades.
This will prevent smears and reduce wiping
noises caused by residue on the windshield.
Washing by hand
In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements in each coun-
try.
XDo not use hot water and do not wash the
vehicle in direct sunlight.
XUse a soft sponge to clean.
XUse a mild cleaning agent, such as a car
shampoo approved by smart.
XThoroughly hose down the vehicle with a
gentle jet of water.
XDo not point the water jet directly towards
the air inlet.
XUse plenty of water and rinse out the sponge frequently.
XRinse the vehicle with clean water and dry
thoroughly with a chamois.
XDo not let the cleaning agent dry on the
paintwork.
Carefully remove all deposits of road salt as
soon as possible when driving in winter.
Power washers
GWARNING
The water jet from a circular jet nozzle
(dirt blasters) can cause invisible exte-
rior damage to the tires or chassis compo- nents. Components damaged in this way may
fail unexpectedly. There is a risk of an
accident.
Care155
>> Maintenance and care.
Z

Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced
immediately.
!Always maintain a distance of at least
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information about the
correct distance is available from the
equipment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
Do not aim directly at any of the following:
Rtires
Rdoor gaps, roof gaps, joints, etc.
Relectrical components
Rbattery
Rconnectors
Rlights
Rseals
Rtrim
Rventilation slots
Damaged seals or electrical components
can lead to leaks or failures.
Cleaning the paintwork
!Do not affix:
Rstickers
Rfilms
Rmagnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
XRemove dirt immediately, where possible,
while avoiding rubbing too hard.
XSoak insect remains with insect remover
and rinse off the treated areas afterwards.
XSoak bird droppings with water and rinse
off the treated areas afterwards.
XRemove coolant, brake fluid, tree resin,
oils, fuels and greases by rubbing gently
with a cloth soaked in petroleum ether or
lighter fluid.
XUse tar remover to remove tar stains.
XUse silicone remover to remove wax.
XUse a suitable touch-up stick, e.g. MB
Touch-Up Stick, to repair slight damage to
the paintwork quickly and provisionally. The following cannot always be completely
repaired:
Rscratches
Rcorrosive deposits
Rareas affected by corrosion
Rdamage caused by inadequate care
In such cases, visit a qualified specialist
workshop.
When water no longer forms beads on the paint surface, use the care product Paint Care,
which has been approved by smart. This is the
case approximately every three to five
months, depending on the climate conditions
and the care product used.
If the dirt has penetrated the paint surface or
if the paintwork has become dull, then the
paintwork should be cleaned. Use the care
product Paint Care, which has been approved
by smart to clean the paintwork.
Do not use these care products in the sun or on
the hood while the hood is hot.
Matte finish 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:
Rstrong rubbing of the paintwork with
unsuitable materials
Rfrequent use of automatic car washes
Rwashing the vehicle in direct sunlight
!Never use paint cleaner, buffing or pol-
ishing products, or gloss preserver, e.g.
wax. These products are only suitable for
high-gloss surfaces. Their use on vehicles
with matte finish leads to considerable
surface damage (shiny, mottled areas).
Always have paintwork repairs carried out
at a qualified specialist workshop.
!Do not use wash programs with a hot wax
treatment under any circumstances.
Observe these notes if your vehicle has a
clear 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 a clear matte finish.
156Care
>> Maintenance and care.

iThe vehicle should preferably be washed
by hand using a soft sponge, car shampoo
and plenty of water.
iUse only insect remover and car shampoo
from the range of approved smart care
products.
Cleaning the panoramic roof
!Only use cleaning agents or cleaning
cloths which are suitable for plastic light
lenses. Unsuitable cleaning agents or
cleaning cloths could scratch or damage
the plastic windows of the panoramic roof.
Do not use cleaning agents which contain
solvents.
XClean the plastic panes of the panoramic
roof using a wet sponge and a mild cleaning
agent, e.g. smart car shampoo, a commer-
cially available glass cleaner or cleaning
cloths.
Cleaning the wheels
GWARNING
The water jet from a circular jet nozzle
(dirt blasters) can cause invisible exte-
rior damage to the tires or chassis compo- nents. Components damaged in this way may
fail unexpectedly. There is a risk of an
accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced
immediately.
!Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
!Do not park the vehicle for an extended
period straight after cleaning it, partic-
ularly after having cleaned the wheels with
wheel cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked.
Cleaning the windows
GWARNING
You could become trapped by the wind-
shield wipers if they start moving while
cleaning the windshield or wiper blades.
There is a risk of injury.
Always switch off the windshield wipers
and the ignition before cleaning the wind-
shield or wiper blades.
!Do not use dry cloths, abrasive products,
solvents or cleaning agents containing
solvents 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 a risk of damaging the
windows.
!Clean the water drainage channels of the
windshield and the rear window at regular
intervals. Deposits such as leaves, petals
and pollen may under certain circumstan-
ces prevent water from draining away. This
can lead to corrosion damage and damage to
electronic components.
XClean the inside and outside of the windows
with a damp cloth and a cleaning agent that
is recommended and approved by smart.
Cleaning wiper blades
GWARNING
You could become trapped by the wind-
shield wipers if they start moving while
cleaning the windshield or wiper blades.
There is a risk of injury.
Always switch off the windshield wipers
and the ignition before cleaning the wind-
shield or wiper blades.
!Do not pull the wiper blade. Otherwise,
the wiper blade could be damaged.
!Do not clean wiper blades too often and do
not rub them too hard. Otherwise, the
graphite coating could be damaged. This
could cause wiper noise.

cle and the power washer nozzle. Informa-
tion about the correct distance is availa-
ble from the equipment manufacturer.
XClean sensors 0043of the driving systems
with water, car shampoo and a soft cloth.
Cleaning the exhaust pipe
Impurities combined with the effects of road
grit and corrosive environmental factors may
cause flash rust to form on the surface. You
can restore the original shine of the exhaust
pipe by cleaning it regularly, especially in
winter and after washing.
!Do not clean the exhaust pipe with acid-
based cleaning agents, such as bathroom
cleaner or wheel cleaner.
XClean the exhaust pipe with a care product tested and approved by smart.
Interior care
Cleaning the display
!For cleaning, do not use any of the fol-
lowing:
Ralcohol-based thinner or gasoline
Rabrasive cleaning agents
Rcommercially-available household
cleaning agents
These may damage the display surface. Do
not put pressure on the display surface
when cleaning. This could lead to irrepar-
able damage to the display.
