Tread wear indicators.
Tread wear indicators are narrow treadless bands across the width of the tread. On theside of the tyre are the letters TWI (TreadWear Indicator). When the tyre's tread depthis down to 1.6 mm, the tread depth will belevel in height with the tread wear indicators.Change to new tyres as soon as possible.Remember that tyres with little tread depthprovide very poor grip in rain and snow.

Wheel bolts
Wheel bolts are used to fasten the wheels at the hubs and are available in different ver-sions.
IMPORTANT
The wheel bolts must be tightened to 140 Nm. Overtightening can damage the nutsand the bolts.
Only use rims that are tested and approved by Volvo and which are Volvo genuine acces-sories. Check the torque with a torquewrench.
Locking wheel bolts*Locking wheel bolts* can be used on bothaluminium and steel rims. Under the cargoarea floor there is space for the sleeve for thelockable wheel bolts.

Changing wheels - fitting
It is important that the procedure for fitting the wheel is carried out correctly.
Fitting1. Clean the contact surfaces between
wheel and hub.
2. Put on the wheel. Tighten the wheel bolts thoroughly.
3. Lower the car so that the wheels cannot rotate.
4. Tighten the wheel bolts crosswise. It isimportant that the wheel bolts are tight- ened properly. Tighten to 140 Nm. Checkthe torque with a torque wrench.
5. Refit any full wheel covers.
NOTE
• After a tyre has been inflated, always refit the dust cap in order to avoiddamage to the valve from gravel, dirt,etc.
• Only use plastic dust caps. Metal dustcaps can rust and become difficult tounscrew.
NOTE
The wheel cover outlet for the valve must be positioned over the valve on the wheelrim during fitting.
WARNING
Never crawl under the car when it is raised on the jack. Passengers must leave the car when it is raised on the jack. Park the car such that passengers have the car, or ideally a crash barrier, betweenthemselves and the roadway.
NOTE
The car's regular jack is designed only for use occasionally and for a short time, suchas when changing a wheel with a punc-tured tyre, switching between summertyres and winter tyres, etc. Only the jackbelonging to the specific model is to beused to jack up the car. If the car is to bejacked up more often, or for a longer timethan is required just to change a wheel,use of a garage jack is recommended. Inthis instance, follow the instructions foruse that come with the equipment.
