Using engine oils and oil filters of specifi
cation 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

dations for scheduled oil changes. Failure to
do so will result in engine or emission control
system damage not covered by the smart
Limited Warranty.

Service fluids and capacities

Brake fluid

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
interval.
Only brake fluid approved by smart is recom
mended. Any authorized smart center will
provide you with additional information.
