Setting the air vents
Important safety notes
GWARNING
Very hot or very cold air can flow from the
air vents. This could result in burns or
frostbite in the immediate vicinity of the
air vents. There is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air
outlets. If necessary, redirect the airflow
to another area of the vehicle interior.
GWARNING
If you spray cleaning products or disin-
fectant into the ventilation system of the
vehicle, this could ignite. There is a risk
of fire.
Never spray these or any other substances
into the ventilation system. Always have
work on the ventilation system carried out
at a qualified specialist workshop.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle inte-
rior, please observe the following notes:
Rkeep the air inlet between the service
cover and the windshield free of blockages,
such as ice, snow or leaves.
Rnever cover the air vents or air intake
grilles in the vehicle interior.
iFor optimum climate control in the vehi-
cle, open the air vents fully.

!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.

All passenger car tires must conform to the
statutory safety requirements in addition to
these grades.
iThe actual values for tires are vehicle-
specific and may deviate from the values in
the illustration.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested under controlled conditions on a specified
U.S. government course. For example, a tire
graded 150 would wear one and one-half times
as well on the government test track as a tire
graded 100.
The relative performance of tires depends
upon the actual conditions of their use, how- ever, and may depart significantly from the
norm due to variations in driving habits,
service practices and differences in road
characteristics and climate conditions.
Traction
GWARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
!Avoid wheelspin. This can lead to damage
to the drive train.
The traction grades – from highest to lowest –
are AA, A, B and C. Those grades represent the
tire's ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C may
have poor traction performance.
The safe speed on a wet, snow covered or icy
road is always lower than on dry road surfa-
ces.
You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.
smart recommends a minimum tread depth of
00CF in (4 mm) on all four winter tires. Observe
the legally required minimum tire tread
depth (
Ypage 178). Winter tires can reduce
the braking distance on snow-covered surfa- ces in comparison with summer tires. The
braking distance is still much further than on
surfaces that are not icy or covered with snow.
Take appropriate care when driving.
Further information on winter tires (M+S
tires) (
Ypage 179).
Temperature
GWARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive load-
ing, either separately or in combination,
can cause excessive heat build-up and pos- sible tire failure.
The temperature grades are A (the highest), B
and C. They represent the tire's resistance to
the generation of heat and its ability to dis-
sipate heat when tested under controlled con-
ditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudden tire failure. The grade C
corresponds to a level of performance which
all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard No.
109. Grades B and A represent higher levels of
performance on the laboratory test wheel than
the minimum required by law.
