gas mileage INFINITI QX30 2017 Owners Manual

Exhaust system:
Make sure there are no loose supports, cracks
or holes. If the sound of the exhaust seems
unusual or there is a smell of exhaust fumes,
immediately have the exhaust system in-
spected. It is recommended you visit an INFINITI
retailer for this service. SeePrecautions when
starting and drivingin the5. Starting and
drivingsection.
Fluid leaks
:
Check 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 if gasoline fumes are evi-
dent, check for the cause and have it corrected
immediately.
Radiator and hoses
:
Check the front of the radiator and clean off any
dirt, insects, leaves, etc., that may have accu-
mulated. Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody
:
The underbody is frequently exposed to corro-
sive substances such as those used on icy
roads or to control dust. It is very important to
remove these substances, otherwise rust willform on the floor pan, frame, fuel lines and
around the exhaust system. At the end of
winter, the underbody should be thoroughly
flushed with plain water, being careful to clean
those areas where mud and dirt may accumu-
late. For additional information, seeCleaning
