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 trunk lid 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 .

� Keep everyone and flammable materials away from the exhaust pipe while the engine is running . The exhaust gas is very hot .
