Using tires other than those approved by
smart can have detrimental effects, such as
• poor handling characteristics
• increased noise
• increased fuel consumption
Moreover, tires and rims not approved by
smart may, under load, exhibit dimensional
variations and different tire deformation
characteristics that could cause them to come
into contact with the vehicle body or axle
parts. Damage to the tires or the vehicle may
be the result.

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
