Instructions for checking tire inflation pressure
■
When checking tire inflation pressure, observe the following:
Check only when the tires are cold.
●
If your vehicle has been parked for at least 3 hours or has not been driven for more
than 1 mile or 1.5 km, you will get an accurate cold tire inflation pressure reading.
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 gener-
●
ated in the tire. Do not reduce tire inflation pressure after driving.
Never exceed the vehicle capacity weight.
●
Passengers and luggage weight should be placed so that the vehicle is balanced.
CAUTION
Proper inflation is critical to save tire performance
■
Keep your tires properly inflated.
If the tires are not properly inflated, the following conditions may occur which
could lead to an accident resulting in death or serious injury:
Excessive wear
●
Uneven wear
●
Poor handling
●
Possibility of blowouts resulting from overheated tires
●
Air leaking from between tire and wheel
●
Wheel deformation and/or tire damage
●
Greater possibility of tire damage while driving (due to road hazards, expansion
●
joints, sharp edges in the road, etc.)
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 moisture may get into the valve and cause an air
leak, resulting in decreased tire inflation pressure.
