The tire pressure warning system does
not function properly under certain cir-
cumstances. In the following cases, the
low tire pressure warning light may not
come on even if the tire inflation pres-
sure is low, or it may come on when
the tire inflation pressure is actually
normal.
R
A compact spare tire, snow tires, or
tire chains are used.
R
The tire inflation pressure is excessive-
ly higher than specified, or tire inflation
pressure suddenly drops due to burst-
ing or other causes.
R
The vehicle is driven on a slippery
road surface such as rough or frozen
roads.
R
The vehicle speed is less than 30 km/h
(19 mph) or more than 100 km/h (62
mph), and the driving duration is less
than 5 minutes.
R
The tires differ in tread pattern or
manufacturer.
R
The tires are not the specified size.
R
The tread wear is very different among
the installed tires.

R
The pressure of two or more tires
drops at the same time.
R
Rapid acceleration/deceleration
sharp turns is continued.
R
The loading is over the limit or imbal-
anced.
R
Initialization was not performed correct-
ly after replacing or rotating tires or
wheels.
R
The outside temperature is below 0rC
(32rF) or above 40rC (104rF).
CAUTION
When the tire pressure warning light
comes on, observe the following in-
structions:
R
Adjust the tire inflation pressure to
the specified level as soon as pos-
sible.
R
Avoid abrupt steering wheel maneu-
vering and braking. If the vehicle
tires deteriorate, you could lose
control of the steering wheel or the
brakes, causing death or serious in-
jury.
Note: The tire pressure monitoring
system on your vehicle will warn you
or
when one of your tires is significantly
under- inflated and when some com-
binations of your tires are significant-
ly under- inflated. However, there are
other combinations of
under- inflated tires for which your
tire pressure monitoring system may
not warn you. These other combina-
tions are relatively common, account-
ing for approximately
instances in which vehicles have sig-
nificantly under- inflated tires. For ex-
ample, your system may not warn you
when both tires on the same side or
on the same axle of your vehicle are
significantly under- inflated. It is par-
ticularly important, therefore, for you
to check the tire pressure in all of
your tires regularly and
proper pressure.
