1-1. For safe use
Exhaust gas precautions
Harmful substance to the
human body is included in
exhaust gases if inhaled.
WARNING
Exhaust gases include harmful car-
bon monoxide (CO), which is color- less and odorless. Observe the following precautions.
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 back door closed.
●If you smell exhaust gases in the vehicle even when the back door is closed, open the windows and have
the vehicle inspected at any autho- rized Toyota retailer or Toyota authorized repairer, or any reliable
repairer as soon as possible.
■When parking
●If the vehicle is in a poorly venti- lated area or a closed area, such as a garage, stop the engine.
●Do not leave the vehicle with the engine on 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
vehicle.
■Exhaust pipe
The exhaust system needs to be checked periodically. If there is a hole
or crack caused by corrosion, dam- age to a joint or abnormal exhaust noise, be sure to have the vehicle
inspected and repaired by any autho- rized Toyota retailer or Toyota autho-rized repairer, or any reliable repairer.

■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crys-tal information display. At extremely
low temperatures, the information dis- play monitor may respond slowly, and display changes may be delayed.
