seems unusual or there is a smell of exhaust fumes, immediately locate the trouble
and correct it.MA-19
UnderbodyThe underbody is frequently exposed to corrosive substances such as those used
on icy roads or to control dust. It is very important to remove these substances, oth-
erwise rust will form on the floor pan, frame, fuel lines and around the exhaust sys-
tem. At the end of winter, the underbody should be thoroughly flushed with plain
water, being careful to clean those areas where mud and dirt can easily accumu-
late.—
Fluid leaksCheck under the vehicle for fuel, oil, water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the air conditioner after use is normal.
If you should notice any leaks or gasoline fumes are evident, check for the cause
and correct it immediately.—
