Checki ngtire pressures manually To
determine andsetthe correct tire
pressure, proceedasfollows:
X Remove thevalve capofthe tire that isto
be checked.
X Press thetire pressure gaugesecurely onto
the valve.
X Read thetire pressure andcompare itwith
the recommended valueonthe Tire and
Loading Information placardonthe
B-pillar onthe driver's sideofyour vehicle.
X Ifnecessary, increasethetire pressure to
the recommended value(Ypage 353).
X Ifthe tire pressure istoo high, release air
by pressing downthemetal pininthe valve
using thetipofapen, forexample. Then check
thetire pressure againusing thetire

more tiresaresignificantly underinflated.
Stop thevehicle assoon aspossible and
inflate thetires tothe pressure specified on
the vehicle's TireandLoading Information
placard or(where available)inthe tire
pressure table.
Driving onasignificantly underinflated tire
causes thetire tooverheat andcanlead to
tire failure. Underinflation alsoreduces fuel
efficiency andtiretread life,and may affect
the vehicle's handlingandstopping ability.
Check alltires when cold,including thespare
