DRIVING TIPS 427
8-3. ENGINE EXHAUST GAS( Carbon Monoxide) s08ac
WARNING
. Never inhale engine exhaust gas. Engine exhaust gas contains carbon monoxide, a colorless and odorless gas which is dangerous, or even lethal, if inhaled.
. Always properly maintain the engine exhaust system to prevent engine exhaust gas from entering the vehicle.
. Never run the engine in a closed space, such as a garage, except for the brief time needed to drive the vehicle in or out of it.
. Avoid remaining in a parked vehicle for a long time while the engine is running. If that is unavoidable, then use the ventilation fan to force fresh air into the vehicle.
. Always keep the front ventilator inlet grille free from snow, leaves or other obstructions to ensure that the ventilation system always works properly.
. If at any time you suspect that exhaust fumes are entering the vehicle, have the problem checked and corrected as soon as possible. If you must drive under these conditions, drive only with all windows fully open.
. Keep the rear gate closed while driving to prevent exhaust gas from entering the vehicle.
NOTE
Due to the expansion and contraction of the metals used in the manufacture of the exhaust system, you may hear a crackling sound coming from the exhaust system for a short time after the engine has been shut off. This sound is normal.
8-4. CATALYTIC CONVER- TER s08ad
WARNING
. Avoid fire hazards. Do not drive or park the vehicle anywhere near flammable materials( e. g. grass, paper, rags or leaves), because the catalytic converter operates at very high temperatures.
. Keep everyone and flammable materials away from the exhaust pipe while the engine is running. The exhaust gas is very hot.

The catalytic converter is installed in the exhaust system. It serves as catalyst to reduce HC, CO and NOx in exhaust gases, thus providing cleaner exhaust.
To avoid damage to the catalytic converter:
. Use only unleaded gasoline. Even a small amount of leaded gasoline will damage the catalytic converter.
. Never start the engine by pushing or pulling the vehicle.
. Avoid racing the engine.
. Never turn off the ignition switch while the vehicle is moving.
. Keep your engine tuned-up. If you feel the engine running rough( misfiring, backfiring or incomplete combustion), have your vehicle checked and re-
