Exhaust gas precautions
Harmful substance to the human
body is included in exhaust gases if

may lead to death or a serious health
hazard.
■Important points while driving
●Keep the trunk lid closed.
●If you smell exhaust gases in the vehi-
cle even when the trunk lid is closed,
open the windows and have the vehi-
cle inspected at your Lexus dealer as

■When parking
●If the vehicle is in a poorly ventilated
area or a closed area, such as a
garage, stop the engine tem>.

park the vehicle in an open space and
ensure that exhaust fumes do not enter

snowing. If snowbanks build up around
the vehicle while the engine is running
