rims MERCEDES-BENZ ML320 1997 Complete Owner's Guide

Rims
D
When changing wheels, for instance, when replacing steel

wheels with light-alloy rims, ensure that the wheel bolts

required for the spare wheel are stored in a clearly visible

location.

D
Since December 1994 models 202 and 124 with special

equipment light alloy disk wheels, are supplied with a sheet

steel spare wheel instead of a light alloy spare wheel. The

necessary wheel bolts are included with the steel spare wheel.

D
Only use approved Mercedes-Benz rims of the same version.

D
Reinforced steel rims are identified by a sticker on the wheel

disc.

D
The wheel bolts on steel and light-alloy rims should always be

tightened to the specified tightening torque using a torque
wrench.

It is not necessary to retorque the lug bolts after approximately

100 to 500 km.
D

The seat for the tire bead must display no corrosion marks.

D
Before inserting a new rubber valve, clean the contact surfaces

on the disk wheel.

On sheet steel-disk wheel wheel trims must be fitted to support

the rubber valve.


Damaged or deformed rims must not be repaired.

Tire pressure monitor
D
Before replacing a tire, check the date of manufacturer of the

wheel sensor: wheel sensors which are more than 5 years old

must be replaced.

D
Use STAR DIAGNOSIS to read out the actual values of the tire

pressure monitor. Check the remaining life of the wheel sensor

battery, replace the wheel sensor if necessary.
