Honda 2008 Ridgeline Owner's Manual page 215

For example, if you check and fill
your tires in a warm area, then drive
in extremely cold weather, the tire
pressure will be lower than
measured and could be underinflated
and cause the low tire pressure
indicator to come on. Or, if you
check and adjust your tire pressure
in cooler conditions, and drive into
extremely hot conditions, the tire
may become overinflated. However,
the low tire pressure indicator will
not come on if the tires are
overinflated.
Refer to page 267 for tire inflation
guidelines.
Tire Pressure Monitoring System (TPMS)
Although your tire pressure is
monitored, you must manually check
the tire pressures monthly.
Each tire, including the spare, should
be checked monthly when cold and
set to the recommended inflation
pressure as specified in the vehicle
placard and this owner's manual (see
page 268 ).
Tire Pressure Monitor
The appropriate tire indicator and
low tire pressure indicator comes on
if a tire becomes significantly
underinflated. See Low Tire
Pressure Indicator on page
Tire Pressure Monitoring
System (TPMS) Indicator
This indicator comes on and stays on
if there is a problem with the tire
pressure monitoring system.
If this happens, the system will shut
off and no longer monitor tire
pressures. Have the system checked
by your dealer as soon as possible.
If the low tire pressure indicator or
TPMS indicator comes on, the VSA
system automatically turns on even
when the VSA system is turned off
by pressing the VSA OFF switch
(see page 216 ). If this happens, you
208 . cannot turn the VSA system off by
pressing the VSA off switch again.
When you restart the vehicle with
the compact spare tire, the TPMS
indicator may also come on and stay
on.
