CAUTION
•
Your vehicle's tires will heat up during use,
with a corresponding increase in air pres-
sure. This is normal; do not release air from
the tires when they are hot.
Always check tire pressures before driving,
when the tires are cold.
•
Pay particularly close attention to the air
pressure in new tires. New tires tend to
stretch slightly as they settle, with a corre-
sponding decrease in air pressure.
•
Never fail to install tire valve caps after
checking or adjusting the air pressure.
Unless the valve caps are replaced, foreign
matter may interfere with the valves and
cause air to leak out.
NOTE:
•
The tire inflation pressures will be higher just
after vehicle operation than before vehicle oper-
ation. The increases in pressure are not abnor-
mal; they occur because the air in the tires
expands as the tires get hot while the vehicle is
moving. Do not release air from the tires at this
time. The pressures will return to normal as the
tires cool down.
•
The pressure drops naturally as time passes.
You should therefore check the tire pressure
using an air gauge.
