! Do not use any special lubricant
additives, as these may increase wear
and damage the drive assemblies. Using
special additives not approved by smart
may cause damage not covered by the
smart Limited Warranty. More
information on this subject is available
at any smart center.
Checking engine oil level
! Check the engine oil level at regular
intervals.
When checking the engine oil level
R the vehicle must be parked on level
ground
R the vehicle must have been stationary for
at least five minutes with the engine
turned off
XTurn off the engine.XEngage the parking brake.XOpen the tailgate.XOpen the engine compartment cover
( Y page 107).
The oil dipstick is located in the engine
compartment on the passenger side.
XPull out oil dipstick 0046.XWipe oil dipstick 0046 clean with a clean
cloth.XFully insert oil dipstick 0046 into the
dipstick guide tube.XPull out oil dipstick 0046 again after
approximately one minute to obtain
accurate reading.
The oil level is correct when it is
between lower mark 008A (minimum) and
upper mark 0047 (maximum) on both sides
of oil dipstick 0046.XFully insert oil dipstick 0046 into the
dipstick guide tube again.XIf necessary, add engine oil
( Y page 109).

The filling quantity between the upper
and lower marks on the oil dipstick is
approximately 1.1 US qt (1.0 l).
Adding engine oil
! Only use approved engine oils and oil
filters required for vehicles with
Maintenance System. For a listing of
approved engine oils and oil filters
contact an authorized smart center.
Using engine oils and oil filters of
specification other than those expressly
required for the Maintenance System, or
changing of oil and oil filter at change
intervals longer than those called for by
the Maintenance System will result in
engine or emission control system
damage not covered by the smart Limited
Warranty.
GWarning!
When adding engine oil, always use a funnel
to avoid spilling oil on any hot parts such
as the catalytic converter or exhaust
system.
If this should happen, however, the engine
must be thoroughly cleaned before you
continue your trip. The engine oil could
otherwise ignite.

XPosition jack 0046 under take-up
bracket 0047 so that it is always vertical
as seen from the side, even if the vehicle
is parked on an incline.
The take-up brackets are identified by
the embossed recesses in the area of the
door sills.
! Only position the jack on the
designated take-up brackets. Otherwise,
the vehicle could be damaged.
XJack up the vehicle until the wheel is a
maximum of 1.2 in (3 cm) from the ground.XUnscrew and remove the wheel bolts.
! Do not place wheel bolts in sand or dirt.
This could result in damage to the wheel
bolts and wheel hub threads.
XRemove the wheel.
Mounting the wheel
GWarning!
Always replace wheel bolts that are
damaged or rusted.
Never apply oil or grease to wheel bolts.
Damaged wheel hub threads should be
repaired immediately. Do not continue to
drive under these circumstances! Contact
an authorized smart Center or call
Roadside Assistance.
Incorrect wheel bolts or improperly
tightened wheel bolts can cause the wheel
to come off. This could cause an accident.
Be sure to use the correct wheel bolts.GWarning!
Only use genuine smart wheel bolts. Other
wheel bolts may come loose.
Do not tighten the wheel bolts when the
vehicle is raised. Otherwise the vehicle
could fall off the jack.
XClean contact surfaces of wheel and wheel
hub.
! To avoid paint damage, place wheel flat
against hub and hold it there while
installing first wheel bolt.
XGuide the wheel onto the wheel hub and
push it on.XInsert two wheel bolts and tighten them
slightly.XVehicles with wheel trim cap on steel
rim: Attach the wheel trim cap so that it
is held by the two wheel bolts.XInstall last wheel bolt and tighten it
slightly.XLower the vehicle until the vehicle is
resting fully on its own weight.XRemove the jack.XTighten the wheel bolts. Observe a
tightening torque of 80 lb-ft (110 Nm).GWarning!
Have the tightening torque checked after

Engine oils are specifically tested for
their suitability in our engines and
durability for our service intervals.
Therefore, only use engine oils and oil
filters required for vehicles with the
Maintenance System. For a listing of
approved engine oils and oil filters
contact an authorized smart center.
! Using engine oils and oil filters of
specification other than those expressly
required for the Maintenance System, or
changing of oil and oil filter at change
intervals longer than those called for bythe Maintenance System will result in

damage not covered by the smart Limited

Please follow Maintenance System
recommendations for scheduled oil
changes. Failure to do so will result in
engine or emission control system
damage not covered by the smart Limited

point or a windshield washer concentrate labeled for winter and water for temperatures below freezing
point.206Service fluids and capacities>> Technical data.* optional451_AKB; 3; 22, en-USd2ureepe,Version: 2.11.8.12009-07-27T09:36:34+02:00 - Seite 206
Viscosity grades for engine oils
Using the chart below, select oil viscosity
according to the lowest air temperature
expected before the next oil change.
Engine oil additives
! Do not blend oil additives with engine
oil. They may damage the engine.
Damage or malfunctions resulting from
blending oil additives are not covered
by the smart Limited Warranty. Any
authorized smart center will provide you
with additional information.
Air conditioning refrigerant
R134a (HFC) refrigerant and special
PAG lubricating oil are used in the air
conditioning system.
! Never use R 12 (CFC) or mineral-based
lubricating oil. Otherwise damage to the
system will occur.
Brake fluid
GWarning!
During vehicle operation, the boiling
point of the brake fluid is continuously
reduced through the absorption of moisture
from the atmosphere. Under extremely
strenuous operating conditions, this
moisture content can lead to the formation
of bubbles in the system, thus reducing the
system’s efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s
Maintenance Booklet for replacement
interval.
Only brake fluid approved by smart is
recommended. Any authorized smart center
will provide you with additional
information.
Premium unleaded gasoline
GWarning!
Gasoline is highly flammable and
poisonous. It burns violently and can cause
serious personal injury.
Never allow sparks, flame or smoking
materials near gasoline!
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and skin or clothing
contact. Extinguish all smoking materials.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging to
your health.
! To maintain the engine’s durability
and performance, premium unleaded
gasoline must be used. If premium
unleaded gasoline is not available and
low octane fuel is used, follow these
precautions:
R Have the fuel tank only partially filled
with unleaded regular gasoline and
fill up with premium unleaded
gasoline as soon as possible.
R Avoid full throttle driving and abrupt
acceleration.
R Do not exceed an engine speed of
3 000 rpm if the vehicle is loaded with
