If at any time you suspect that exhaust fumes are entering the
vehicle, have the problem checked and corrected as soon as pos-
sible. If you must drive under these conditions, drive only with allwindows fully open. Keep the trunk lid or 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 soundcoming from the exhaust system for a short time after the enginehas been shut off. This sound is normal.
Catalytic converter
WARNING
Avoid fire hazards. Do not drive or park the vehicle anywhere
near flammable materials (e.g. grass, paper, rags or leaves), be-
cause the catalytic converter operates at very high temperatures. Keep everyone and flammable materials away from the ex-
haust pipe while the engine is running. The exhaust gas is veryhot.
