WARNING
If the tire pressu redrops repeatedly,the
wheel ,valve ortire may bedama ged.Tire
pressu rethat istoo low may resul tin atire

WARNING
If you fitunsui table accessorie sonto tire
valves ,the tire valves maybeoverloa dedand
malfu nction, whichcancause tirepressu re
loss. Duetotheir desig n,retrofitted tirepres-
sure monitors keepthetire valve open. This
can also resul tin tire pressu reloss. There isa
risk ofan accident.
Only screw thestandard valvecaporother

Use asuita blepressu regau getocheck thetire
pressu re.The outer appearance ofatire does
not permit anyrelia bleconclusion aboutthe tire
pressu re.On vehicle sequi pped withtheelec-
tronic tirepressu remonitor, thetire pressu re
can bechecked inthe on-board computer. The
tiretemperature andpressu reincrease
when thevehicle isin motion. Thisisdepende nt
on the driving speedandtheload .
Therefore, youshoul donly correct tirepres-
sures whenthetires arecold.
The tires arecold:
R ifthe vehicle hasbeen parked withthetires
out ofdirect sunlightfor atlea stthree hours
and
R ifthe vehicle hasbeen driven lessthan 1mile
(1.6 km)
The tiretemperature changesdependingon the
outsid etemperature ,the vehicle speedandthe
tire load .If the tire temperature changesby
18 ‡(10 †), thetire pressu rechanges by
appro ximately 10kPa (0.1 bar/ 1.5psi).Take
this into account whenchecking thepressu reof
warm tires.Onlycorrect thetire pressu reifit is
too low forthe current operatingconditions. If
you check thetire pressu rewhen thetires are
warm, theresul tingvaluewil lbe highe rthan if
the tires were cold.Thisisnormal. Donot
reduce thetire pressu reto the valu especifie d
for cold tires. Thetirepressu rewou ldotherwise
be too low.
Observe therecommended tirepressu resfor
