1-1. For safe use
For safety and security
Exhaust gas precautions
Harmful substance to the human
body is included in exhaust gases if
inhaled.
WARNING
Exhaust gases include harmful carbon monoxide (CO), which is colorless and odorless. Observe the following precau-
tions. Failure to do so may cause exhaust gases enter the vehicle and may lead to an
accident caused by light-headedness, or 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 any authorized Lexus retailer or Lexus authorized repairer,
or any reliable repairer as soon as pos- sible.
■When parking
●If the vehicle is in a poorly ventilated area or a closed area, such as a garage, stop the engine tem>.
●Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and ensure that exhaust fumes do not enter
the vehicle interior.
●Do not leave the engine running in an area
with snow build-up, or where it is snowing. If snowbanks build up around the vehicle while the engine is running
, exhaust gases may collect and enter the vehi-cle.
■Exhaust pipe
The exhaust system needs to be checked periodically. If there is a hole or crack
caused by corrosion, damage to a joint or abnormal exhaust noise, be sure to have the vehicle inspected and repaired
by any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
