Do not ignore the TPMS warning light
when it is turned on or flashing:
Continuing to drive the vehicle while
ignoring the illumination/flashing of
the TPMS warning light is dangerous
because a tyre may burst which could
lead to an accident. Take appropriate
measures as soon as possible.
NOTE
While the TPMS is learning the tyre
positions, such as immediately after a
tyre position has been changed, the
tyre pressure at the tyre position prior
to it being changed is displayed until
the system completes the learning. For
this reason, the tyre pressures
displayed for the tyre positions may be
different from the actual tyre pressures
at the tyre positions.
Action to be taken
Adjust the tyre pressures to the
appropriate pressures.
Refer to Tyre Inflation Pressure on page
6-41.
Warning/Indicator Lights and Warning Sounds
CAUTION
Adjust the tyre pressures while the
tyres are cool. Because the air
pressure in the tyres fluctuates
depending on the temperature,
before adjusting the tyre pressures,
let the vehicle sit for an hour or drive
it only within a 1.6 km (1 mile)
distance. If the tyre pressures are
adjusted while the tyres are warm,
the tyre pressures may decrease
below the specified air pressure after
cooling down which could turn on
the warning light. In addition,
because the air pressure in the tyres
decreases when the ambient
temperature is low, if the ambient
temperature increases, an
illuminated TPMS warning light may
turn off. Under any circumstances,
always adjust the tyre pressures while
the tyres are cool.
After adjusting the tyre pressures, the
TPMS warning light turns off. If the
TPMS warning light does not turn off,
drive the vehicle at a speed of about
25 km (16 mph) or faster for 3
minutes or longer and make sure the
warning light turns off.
If the TPMS warning light remains on
even after adjusting the tyre pressures,
one of the tyres may have a puncture.
