mended and approved by smart.
Cleaning the seat covers
General notes
!Do not use a microfiber cloth to clean
covers made out of real leather, artificial leather or DINAMICA. If used often, these
can damage the cover.
iNote that regular care is essential to
ensure that the appearance and comfort of
the covers is retained over time.
Genuine leather seat covers
Leather is a natural product.
It exhibits natural surface characteristics,
for example:
RDifferences in the texture
Rmarks caused by growth and injury
RSlight nuances of color
These are characteristics of leather and not
material defects.
!To retain the natural appearance of the
leather, observe the following cleaning
instructions:
RClean genuine leather covers carefully
with a damp cloth and then wipe the cov-
ers down with a dry cloth.
RMake sure that the leather does not
become soaked. It may otherwise become
rough and cracked.
ROnly use leather care agents that have
been recommended by smart. You can
obtain these from a qualified specialist
workshop.
Seat covers of other materials
!Observe the following when cleaning:
Rclean artificial leather covers with a
cloth moistened with a solution contain-
ing 1% detergent (e.g. dish washing liq-
uid).
Rclean cloth covers with a microfiber
cloth moistened with a solution contain-
ing 1% detergent (e.g. dish washing liq-
uid). Rub carefully and always wipe
entire seat sections to avoid leaving
visible lines. Leave the seat to dry
afterwards. Cleaning results depend on
the type of dirt and how long it has been
there.
Rclean DINAMICA covers with a damp cloth.
Make sure that you wipe entire seat sec-
tions to avoid leaving visible lines.
Cleaning the seat belts
GWARNING
Seat belts can become severely weakened if bleached or dyed. This could cause the seat
belts to tear or fail, for instance, in the
event of an accident. This poses an
increased risk of injury or fatal injury.
Never bleach or dye the seat belts.
!Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts by
heating at temperatures above 176 ‡(80 †)
or in direct sunlight.
XUse clean, lukewarm water and soap solu-
tion.

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).

Rim
This is the part of the wheel on which the tire
is mounted.
GAWR (Gross Axle Weight Rating)
The GAWR is the maximum gross axle weight
rating. The actual load on an axle must never
exceed the gross axle weight rating. The
gross axle weight rating can be found on the
vehicle identification plate on the B-pillar
on the driver's side.
Speed rating
The speed rating is part of the tire identi-
fication. It specifies the speed range for
which the tire is approved.
GVW (Gross Vehicle Weight)
The gross vehicle weight includes the weight
of the vehicle including fuel, tools, the spare
wheel, accessories installed, occupants, lug-
gage and the drawbar noseweight, if appli-
cable. The gross vehicle weight must not
exceed the gross vehicle weight rating GVWR
as specified on the vehicle identification
plate on the B-pillar on the driver's side.
GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permissible gross
weight of a fully loaded vehicle (the weight of
the vehicle including all accessories, occu-
pants, fuel, luggage and the drawbar nose-
weight, if applicable). The gross vehicle
weight rating is specified on the vehicle
identification plate on the B-pillar on the
driver's side.
Maximum loaded vehicle weight
The maximum weight is the sum of:
Rthe curb weight of the vehicle
Rthe weight of the accessories
Rthe load limit
Rthe weight of the factory installed optional
equipment
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa corre-
sponds to 1 psi. Another unit for tire pressure
is bar. 100 kilopascals (kPa) are the equiva-
lent of 1 bar.
Load index
In addition to the load-bearing index, the
load index may also be imprinted on the side-
wall of the tire. This specifies the load-
bearing capacity more precisely.
Curb weight
The weight of a vehicle with standard equip-
ment including the maximum capacity of fuel,
oil and coolant. It also includes the air-con-
ditioning system and optional equipment if
these are installed in the vehicle, but does
not include passengers or luggage.
Maximum load rating
The maximum load rating is the maximum per-
missible weight in kilograms or pounds for
which a tire is approved.
Maximum permissible tire pressure
Maximum permissible tire pressure for one
tire.
Maximum load on one tire
Maximum load on one tire. This is calculated by dividing the maximum axle load of one axle
by two.
PSI (pounds per square inch)
A standard 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
outward force to each square inch of the tire'ssurface. 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:
Rif the vehicle has been parked with the
tires out of direct sunlight for at least
three hours and
Rif the vehicle has not been driven further
than 1 mile (1.6 km)

Direction of rotation
Tires with a specified direction of rotation
have additional benefits, e.g. if there is a
risk of hydroplaning. These advantages can
only be gained if the tires are fitted corre-
sponding to the direction of rotation.
An arrow on the sidewall of the tire indicates
its correct direction of rotation.
Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the
tires from oil, grease, gasoline and diesel.

The vehicle may only be raised at the desig-
nated jacking points on the sill.
The jacking points are located just behind
the wheel housings of the front wheels and
just in front of the wheel housings of the rear
wheels (arrows). You can identify the jacking
points by the triangular indentations on the
sill.
To avoid damage, position the jack centrally
under the triangular indentations.
XPosition jack 0044centrally under the tri-
angular indentations at the jacking points on the sill 0043.
Example
XMake sure the foot of the jack is directly
beneath the jacking point.
XRaise the vehicle with jack 0044until the
tire is a maximum of 1.2 in (3 centimeters)
off the ground.

!Do not place wheel bolts in sand or on a
dirty surface. The bolt and wheel hub
threads could otherwise be damaged when
you screw them in.
XUnscrew the wheel bolts.
XRemove the wheel.
Mounting a new wheel
GWARNING
Oiled or greased wheel bolts or damaged
wheel bolts/hub threads can cause the wheel
bolts to come loose. As a result, you could
lose a wheel while driving. There is a risk of accident.
Never oil or grease wheel bolts. In the event
of damage to the threads, contact a quali-
fied specialist workshop immediately.
Have the damaged wheel bolts or hub threads
replaced/renewed. Do not continue driv-
ing.
GWARNING
If you tighten the wheel bolts or wheel nuts when the vehicle is raised, the jack could
tip over. There is a risk of injury.

Fuel consumption information
HEnvironmental note
CO
2(carbon dioxide) is the gas which sci-
entists believe to be principally respon-
sible for global warming (the greenhouse
effect). Your vehicle's CO
2emissions are
directly related to fuel consumption and
therefore depend on:
Refficient use of the fuel by the engine
Rdriving style
Rother non-technical factors, such as
environmental influences, road condi-
tions or traffic flow
You can minimize your vehicle's CO
2emis-
sions by driving carefully and having it
serviced regularly.
The vehicle will use more fuel than usual in
the following situations:
Rat very low outside temperatures
Rin city traffic
Ron short journeys
Rin mountainous terrain
Engine oil
General notes
!Never use engine oil or an oil filter of a
specification other than is necessary to
fulfill the prescribed service intervals.
Do not change the engine oil or oil filter in order to achieve longer replacement inter-
vals than those prescribed. You could oth-
erwise cause engine damage or damage to
the exhaust gas aftertreatment.
Follow the instructions in the service
interval display regarding the oil change.
Otherwise, you may damage the engine and
the exhaust gas aftertreatment.
When handling engine oil, observe the impor-
tant safety notes on service products
(
Ypage 207).
The engine oils are matched to the perform-
ance of smart engines and service intervals.
You should therefore only use engine oils and
oil filters that are approved for vehicles
with maintenance systems.
Consult a smart center to view a list of
approved engine oils and filters. Or visit the
website http://bevo.mercedes-benz.com.
The table shows which engine oils have been
approved for your vehicle.

Engine oil viscosity
Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscos-
ity, this means that it is thick; a low viscos-
ity means that it is thin.
Select an engine oil with an SAE (viscosity)
classification suitable for the prevailing
outside temperatures. The table shows you
which SAE classifications are to be used. The
low-temperature properties of engine oils
can be significantly impaired during oper-
ation due to, for example, aging or soot and
fuel accretion. It is therefore strongly rec-
ommended that you carry out regular oil
changes using an approved engine oil with
the appropriate SAE classification.
Brake fluid
When handling brake fluid, observe the
important safety notes on service products
(
Ypage 207).
The brake fluid change intervals can be found
in the Maintenance Booklet.
Only use brake fluid approved by Mercedes-
Benz according to MB Approval 331.0.
Information about approved brake fluid can
be obtained at any qualified specialist work-
shop or on the Internet at
http://bevo.mercedes-benz.com.
iHave the brake fluid regularly replaced at
a qualified specialist workshop and the
replacement confirmed in the Maintenance
Booklet.
Coolant
General notes
!Only add coolant that has been premixed
with the desired antifreeze protection.
You could otherwise damage the engine.
Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service Products, MB BeVo 310.1, e.g. on
the Internet at
http://bevo.mercedes-benz.com. Or con-
tact a qualified specialist workshop.
!Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not sufficiently protected from corrosion and
overheating.
iHave the coolant regularly replaced at a
qualified specialist workshop and the
replacement confirmed in the Maintenance
Booklet.
Comply with the important safety precautions
for service products when handling coolant
(
Ypage 207).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
Rcorrosion protection
Rantifreeze protection
Rraising the boiling point
If the coolant has antifreeze protection down
to -35 ‡(-37 †), the boiling point of the cool-
ant during operation is approximately 266 ‡
(130 †).
The antifreeze/corrosion inhibitor concen-
tration in the engine cooling system should:
Rbe at least 50 %. This will protect the
engine cooling system against freezing
down to around -13‡(-25 †).
Rnot exceed 50 % (antifreeze protection down
to-35 ‡[-37 †]). Otherwise, heat will not be
dissipated as effectively.
smart recommends an antifreeze/corrosion
inhibitor concentrate in accordance with MB
Specifications for Operating Fluids 310.1 or
325.6.
