To avoid hazardous situations:
R never mount snowchains onthe rear

! On
some tiresizes there isnot enough
space forsnow chains. Toavoid damage to
the vehicle ortires, observe the"Wheel and

If you fitunsui table accessorie sonto tire

pressu remonitors keepthetire valve open.
This canalso resul tin tire pressu reloss.
There isarisk ofan accident.
Only screw thestandard valvecaporother

Use asuita blepressu regau getocheck the

The tiretemperature andpressu reincrease
when thevehicle isin motion. Thisisdepend-

Therefore, youshoul donly correct tirepres-

The tires arecold:
R ifthe vehicle hasbeen parked withthetires
out ofdirect sunlightfor atlea stthree hours
and
R ifthe vehicle hasbeen driven lessthan
1 mile (1.6km)
The tiretemperature changesdependingon
the outsid etemperature ,the vehicle speed
and thetire load .If the tire temperature
changes by18 ‡(10 †), thetire pressu re
changes byappro ximately 10kPa (0.1 bar/
1.5 psi).Take thisinto account whenchecking
the pressu reofwarm tires.Onlycorrect the
tire pressu reifit is too low forthe current
