Before Driving

Fuel and Emission

 Engine Exhaust (Carbon monoxide)

WARNING

  Do not drive your vehicle if you smell exhaust gas inside the vehicle:

  Engine exhaust gas is dangerous. This gas contains carbon monoxide (CO), which is 
colorless, odorless, and poisonous. When inhaled, it can cause loss of consciousness and 
death. If you smell exhaust gas inside the vehicle, keep all windows fully open and contact 
an Authorized Mazda Dealer immediately.
  

  Do not run the engine when inside an enclosed area:

  Running the engine inside an enclosed area, such as a garage, is dangerous. Exhaust 
gas, which contains poisonous carbon monoxide, could easily enter the cabin. Loss of 
consciousness or even death could occur.
  

  Open the windows or adjust the heating or cooling system to draw fresh air when 
idling the engine:

  Exhaust gas is dangerous. When the vehicle is stopped with the windows closed and 
the engine running for a long time even in an open area, exhaust gas, which contains 
poisonous carbon monoxide, could enter the cabin. Loss of consciousness or even death 
could occur.
  

  Clear snow from underneath and around your vehicle, particularly the tail pipe, before 
starting the engine:

  Running the engine when a vehicle is stopped in deep snow is dangerous. The exhaust 
pipe could be blocked by the snow, allowing exhaust gas to enter the cabin. Because 
exhaust gas contains poisonous carbon monoxide, it could cause loss of consciousness or 
even death to occupants in the cabin.
