WHAT TO DO IN AN EMERGENCY

If you have a tire gauge, remove the
valve cap and check the air pressure. If
the pressure is lower than recom-
mended, drive slowly to the nearest
service station and inflate to the correct
pressure. If it is too high, adjust it until
it is correct. Always reinstall the valve
cap after checking or adjusting tire
pressure. If the cap is not replaced, dirt
and moisture could get into the valve
core and cause air leakage. If you lose
a valve cap, buy another and install it as
soon as possible.

abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine that hose sur-
face nearest to high heat sources, such as
the exhaust manifold.
Inspect the hose routing to assure that the
hose does not come in contact with any
heat source, sharp edges or moving com-
ponent which might cause heat damage or
mechanical wear. Inspect all hose con-
nections, such as clamps and couplings,
to make sure they are secure, and that no
leaks are present. Hose should be re-
placed immediately if there is any evi-
dence of deterioration or damage.
