The air conditioning improves the level of
comfort when driving at high outside
temperatures by cooling and dehumidifying
the air.Nearly all dust particles, pollutants, are
filtered out by an integrated particle filter
before outside air enters the passenger com

partment through the air distribution system.
It also operates when the air conditioning is
switched off and you have switched on the
blower.
The air conditioning only works when the
engine is running and the blower is switched
on. Maximum effectiveness is achieved if you
drive with the windows closed.

305 Engine oils
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 vehi

cles 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 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
system damage not covered by the smart
Limited Warranty.
Please follow Maintenance System recommen

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.
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

based
lubricating oil. Otherwise damage to the sys

tem will occur.
Brake fluidOnly brake fluid approved by smart is recom

mended. Any authorized smart center will
provide you with additional information.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.
