Check tires on all wheels

Check tread as well as outer and inner
sidewalls on all tires for signs of damage such

as cuts, punctures, cracks, breakouts,

separation and ingressed foreign matter. If

damage is present

Check tire wear pattern on all wheels

Greater wear at the shoulder compared to

the center of the tire is normal for the front

wheel tires. Wear on the rear tires is uniformly

distributed across the total tread, whereby

wear on vehicles with rear-wheel drive in the
middle of the tread is somewhat greater than

at the shoulders. In event of unusual tire

pattern:

#

Determine cause for increased tire wear and

rectify, then:

Measure the depth of tread of the tires on al

the wheels and note the measurement in the

table on the maintenance sheet.

Measure depth of tread at point of

greatest wear. Perform measurement at

outside, inside and center of tread.

Minimum depth of tread 1.6 mm.

For safety reasons, tires should be

replaced before the minimum depth of tread is

reached:

D
Summer tires for approx. 2 to 3 mm depth

of tread

D
Winter tires at approx. 4 mm depth of tread

4.1
Change round wheels on front and rear axles
If necessary, and only on vehicles without

mixed tires

Retain running direction of wheels, as
otherwise handling performances and comfort

may be impaired and tire wear increased.

Shift lock cable

For cost-saving reasons the shift lock cable of

the ignition lock to transmission is

discontinued. A cable from the ignition lock to

the brake pedal is used in its place.

Consequently, it is only possible to

withdraw the ignition key when the brake

pedal is depressed
.

The new ignition lock cable (1) does no
longer require to be adjusted.

Phototransistor (models 202, 208, 210)

Point a beam of light at the phototransistor with a pocket lamp, the

display illumination of the LCD displays (outside temperature, trip

odometer, total mileage recorder and electronic clock) must get

brighter.
Instrument cluster with multi-function display

If there are malfunctions (e.g. brake linings worn, coolant level too

low, exterior lamp failure etc.) or system faults (anti-lock brake

system faulty, supplemental restraint system faulty) the warning

display with warning information is inserted in place of outside

temperature, odometer, total mileage recorder and electronic clock.

The warning information is displayed in yellow or red depending on

the fault and a warning tone also sounds.
