Engine oilThe amount of oil your engine needs will de

pend on a number of factors, including driving
style. Increased oil consumption can occur
when
•the vehicle is new
• the vehicle is driven at higher engine
speeds frequently
Engine oil consumption checks should only be
made after the vehicle break
in period.!
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.
G
Warning!
The engine is equipped with a transistor

ized ignition system that utilizes high
voltage. Don not touch any components

Brake fluidThe brake fluid level in the brake fluid
reservoir may be too low if the brake warning
lamp in the instrument cluster comes on
(
page 34) although the parking brake is
released.
!
If you find that the brake fluid in the brake
fluid reservoir has fallen to the minimum mark
or below, have the brake system checked for
brake pad thickness and leaks immediately.
Contact an authorized smart center immedi

ately. Do not add brake fluid as this will not
solve the problem.
The brake fluid reservoir is located in the
front compartment on the driver’s side.

Cap
G
Warning!
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 condi

tions, 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 re

placed regularly. Refer to your vehicle’s
Maintenance Booklet for replacement

Tires and wheels
182
>> Operation Contact an authorized smart center for infor

mation on tested and recommended rims and
tires for summer and winter operation. They
can also offer advice concerning tire service
and purchase.
Modifications to the brake system and wheels
and the use of spacer and brake dust rings
are not permissible.
Important guidelines• Only use sets of tires and rims of the same
type and make.
• Tires must be of the correct size for the
rim.
• Break in new tires for approximately
60 miles (100 km) at moderate speeds.
• Regularly check the tires and rims for
damage. Dented or bent rims can cause tire
inflation pressure loss and damage to the
tire beads.
• If vehicle is heavily loaded, check tire infla

tion pressure and correct as required.
• Do not allow your tires to wear down too far.
Adhesion properties on wet roads are
sharply reduced at tread depths of less
than
1/8in (3 mm).
G
Warning!
Replace rims or tires with the same des

ignation, manufacturer and type as shown
on the original part. Contact an autho

rized smart center for further informa

tion. If incorrectly sized rims and tires
are mounted:
• The wheel brakes or suspension
components can be damaged.
• The operating clearance of the wheels
and the tires may no longer be correct.
G
Warning!
Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires
have sustained damage, replace them.
When replacing rims, only use genuine
smart wheel bolts specified for the
particular rim type. Failure to do so can
result in the bolts loosening and possibly
an accident.
Retreaded tires are not tested or recom

mended by smart, since previous damage
cannot always be recognized on retreads.
The operating safety of the vehicle can

not be assured when such tires are used.

>> Operation
183 Tire care and maintenance
Regularly check your tire inflation pressure
at least once a month. For more information on
checking tire inflation pressure, see
"Recommended tire inflation pressure"
(
page 189)
.
Tire inspection
Every time you check the tire inflation pres

sure, you should also inspect your tires for
the following:
• excessive treadwear (

page 183)
• cord or fabric showing through the tire’s
rubber
• bumps, bulges, cuts, cracks or splits in the
tread or side of the tire
Replace the tire if you find any of the above
conditions.
Life of tire
The service life of a tire is dependent upon
varying factors including but not limited to:
•Driving style
• Tire inflation pressure
•Distance drivenTread depth
Do not allow your tires to wear down too far.
Adhesion properties on wet roads are sharply
reduced at tread depths of less than
1/8in
(3 mm)
.
Treadwear indicators (TWI) are required by
law. These indicators are located in six places
on the tread circumference and become visi

ble at a tread depth of approximately
1/16in
(1.6 mm), at which point the tire is considered
worn and should be replaced.
Recommended minimum tire tread depth:
Summer tires
1/8in (3 mm)
Winter tires
1/6in (4 mm)
G
Warning!
Regularly check the tires for damage.
Damaged tires can cause tire inflation
pressure loss. As a result, you could lose
control of your vehicle.
Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires
have sustained damage, replace them.
G
Warning!
Tires should be replaced after 6 years,
regardless of the remaining tread.

The treadwear indicator appears as a solid
band across the tread.
Storing tires
!
Keep unmounted tires in a cool, dry place
with as little exposure to light as possible.
Protect tires from contact with oil, grease and
gasoline.Cleaning tires
!
Never use a round nozzle to power wash
tires. The intense jet of water can result in
damage to the tire.
Always replace a damaged tire.
Direction of rotationUnidirectional tires offer added advantages,
such as better hydroplaning performance.
To benefit, however, you must make sure the
tires rotate in the direction specified.
An arrow on the sidewall indicates the
intended direction of rotation (spinning) of
the tire.
G
Warning!
Although the applicable federal motor
safety laws consider a tire to be worn
when the treadwear indicators (TWI) be

come visible at approximately
1/16in
(1.6 mm), we recommend that you do not
allow your tires to wear down to that
level. As tread depth approaches 1/8in
(3 mm), the adhesion properties on a wet
road are sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction
varies widely.
