with your state or provincial vehicle registration office, But generally,
if the
new odometer can be set to the mileage total of the old odometer, then
it
must be. But if it can’t, then it’s set at zero. and a label must be put on the
driver‘s door to show the old mileage reading when the new odometer was
installed.

of the warning lights comes on and stays on when you are
driving, or when one of the gages shows there may be a problem, check the
section that tells
you what to do about it. Please follow this manual’s advice.

Downloaded from www.Manualslib.com manuals search engine Oil Pressure Gage
The oil pressure gage shows the engine oil pressure in psi (pounds per
square inch) when the engine is running. Canadian vehicles indicate
pressure
in kPa (kilopascals). Oil pressure may vary with engine speed,
outside temperature and
oil viscosity, but readings above the low pressure
zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a dangerously low oil
level or other problem causing
low oil pressure. Check your oil as soon as
possible.
A CAUTION:
Don’t keep driving if the oil pressure is low. If you do, your
engine can become
so hot that it catches fire. You or others could
be burned. Check your oil as soon
as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil problems can be
costly and is not covered
by your warranty.
