Toyota Tundra Owners Manual: Exhaust gas precautions

Harmful substance to the human body is included in exhaust gases if inhale.



Exhaust gases include harmful carbon monoxide (CO), which is colorless and odorless. Observe the following precautions.

Failure to do so may cause exhaust gases to 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

  • Double Cab and CrewMax models: Keep the back window closed.
  • Double Cab and CrewMax models: If you smell exhaust gases in the vehicle even when the back window is closed, open the windows and have the vehicle inspected at your Toyota dealer as soon as possible.
  • Toyota does not recommend occupying the rear cargo area when it is fitted with a slide-in camper, camper shell or other type cover while the engine is running. This caution applies to both driving and stopped or parked situations with the engine running. Particular care should be taken to prevent exhaust gases from entering camper bodies, trailers or other enclosures on or around your vehicle. If exhaust fumes are detected, open all windows and thoroughly ventilate the area.

■When parking

  • If the vehicle is in a poorly ventilated 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, damage to a joint or abnormal exhaust noise, be sure to have the vehicle inspected and repaired by your Toyota dealer.
