2020 MERCEDES-BENZ CLS COUPE oil change

fi
ed based on the actual operating conditions
and/or loads.
Examples of arduous operating conditions:
R regular city driving with frequent intermedi‐
ate stops
R mainly short-dis tance driving
R frequent operation in mountainous terrain or
on poor road sur faces
R when the engine is of ten le ftidling for long
periods
R operation in particula rly dusty conditions
and/or if air-recirculation mode is frequently
used
In these or similar operating conditions, ha vethe
interior air filter, engine air cleaner, engine oil
and oil filter etc. changed more frequent ly. The
ty re s must be checked more frequently if the
ve hicle is operated under increased loads. Fur‐
th er information can be obtained at a qualified
specialist workshop. Battery disconnection periods

R
rear wheels wear more in the cent reofthe
tyre
Do not drive wi thtyres that ha vetoo little tread
dep th. This significantly reduces traction on wet
ro ads (aquaplaning).
On vehicles with the same front and rear wheel
size, you can inter change the wheels every
5000 to10,000 km, depending on thewe ar.
Ensure the direction of rotation is maintained for
th e wheels.

WARNING Risk of an accident due to
va pour poc kets form ing in the brake sys‐
tem
The brake fluid cons tantly absorbs moi sture
from the air. This lo wersthe boiling point of
th e brake fluid. If the boiling point is too lo w,
va pour poc kets may form inthe brake sys‐
te m when the brakes are applied hard.
This impairs the braking ef fect. #
