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.

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.
Care157

Z

XFold the windshield wiper arms away from
the windshield.
XCarefully clean the wiper blades with a
damp cloth.
XFold the windshield wiper arms back againbefore switching on the ignition.
!Hold the wiper arm securely when folding
back. The windshield could be damaged if
the wiper arm smacks against it suddenly.
Cleaning the exterior lighting
!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 light lenses.
XClean the plastic lenses of the exterior
lighting using a wet sponge and a mild
cleaning agent, e.g. smart car shampoo or
cleaning cloths.
Cleaning the sensors
!If you clean the sensors with a power
washer, make sure that you keep a distance
of at least 11.8 in (30 cm) between the vehi-
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.
XBefore cleaning the display, make sure that
it is switched off and has cooled down.
XClean the display surface using a commer-
cially available microfiber cloth and TFT/
LCD display cleaner.
XDry the display surface using a dry micro-
fiber cloth.
Cleaning the plastic trim
GWARNING
Care products and cleaning agents contain-
ing solvents cause surfaces in the cockpit
to become porous. As a result, plastic parts may come loose in the event of air bag
deployment. There is a risk of injury.
Do not use any care products and cleaning
agents to clean the cockpit.

TIREFIT kit
Important safety notes
TIREFIT is a tire sealant.
You can use TIREFIT to seal punctures of up to
0.16 in (4 mm), particularly those in the tire
tread. You can use TIREFIT at outside tem-
peratures down to 00F84‡(00F820 †).
Flat tire161
>> Breakdown assistance.

XTurn the key to position1in the ignition
lock (Ypage 87).
XPress on/off switch 0084on tire inflation
compressor 0044toI.
The tire inflation compressor is switched
on. The tire is inflated.
iFirst, tire sealant is pumped into the
tire. The pressure can briefly rise to
approximately 600 kPa (6.0 bar/86 psi).
Do not switch off the tire inflation com-
pressor during this phase.
XLet the tire inflation compressor run for a
maximum of 15 minutes. The tire should then
have attained a pressure of at least 180 kPa
(1.8 bar/26 psi).
If a tire pressure of 180 kPa (1.8 bar/26 psi) is
achieved after a maximum of 15 minutes, see
"Tire pressure is achieved" (
Ypage 163).
If a tire pressure of 180 kPa (1.8 bar/26 psi)
has not been achieved after a maximum of
15 minutes, see "Tire pressure is not ach-
ieved" (
Ypage 163).
iIf tire sealant leaks out, allow it to dry. It
can then be removed like a layer of film.
If your clothes are soiled with tire sealant,
have them cleaned with perchloroethylene
at a dry cleaner as soon as possible.
Tire pressure not reached
If a tire pressure of 180 kPa (1.8 bar/26 psi)
has not been achieved after a maximum of
10 minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of
the faulty tire.
XVery slowly drive forwards or reverse
approximately 30 ft (10 m).
XPump up the tire again.
After a maximum of 10 minutes, the tire
pressure must be at least 180 kPa (1.8 bar/
26 psi).
GWARNING
If the required tire pressure is not reached after the specified time, the tire is too
badly damaged. The tire sealant cannot
repair the tire in this instance. Damaged
tires and a tire pressure that is too low can
significantly impair the vehicle's braking
and driving characteristics. There is a
risk of accident.
Do not continue driving. Contact a quali-
fied specialist workshop.
Tire pressure reached
GWARNING
A tire temporarily sealed with tire sealant impairs the driving characteristics and is
not suitable for higher speeds. There is a
risk of accident.
You should therefore adapt your driving
style accordingly and drive carefully. Do
not exceed the specified maximum speed
with a tire that has been repaired using
tire sealant.
The maximum speed for a tire sealed with tire
sealant is 50 mph (80 km/h). The 50 mph
(80 km/h) maximum speed sticker must be
affixed to the instrument cluster within the
driver's field of vision.
!After use, excess tire sealant may run out
of the filler hose. This could cause stains.
Therefore, place the filler hose in the
plastic bag that contained the TIREFIT kit.
HEnvironmental note
Have the used tire sealant bottle disposed
of professionally, e.g. at a qualified spe-
cialist workshop.
If a tire pressure of 180 kPa (1.8 bar/26 psi)
has been achieved after 10 minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of
the faulty tire.
XStow the tire sealant bottle and the tire
inflation compressor.
XPull away immediately.
XStop after driving for approximately
2 miles (3 km) and check the tire pressure
with the tire inflation compressor.
The tire pressure must now be at least
130 kPa (1.3 bar/19 psi).
