● Always use a tire pressure gauge.
It is difficult to judge if a tire is properly
inflated based only on its appearance.
● It is normal for the tire inflation pressure
to be higher after driving as heat is gen-
erated in the tire. Do not reduce tire infla-
tion pressure after driving.
Never exceed the vehicle capacity
●
weight.
Passengers and luggage weight should
be placed so that the vehicle is balanced.

NOTICE
■ When inspecting and adjusting tire
inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or mois-
ture may get into the valve and cause an
air leak, resulting in decreased tire infla-
tion pressure.

Wheels

If a wheel is bent, cracked or heavily
corroded, it should be replaced.
Otherwise, the tire may separate
from the wheel or cause a loss of
handling control.
Wheel selection
When replacing wheels, care should
be taken to ensure that they are equiv-
alent to those removed in load capac-
ity, diameter, rim width and inset

Whenever wheels are replaced, tire pres-
sure warning valves and transmitters must
be installed. (P.380)
