240 Operation
The first 1,500 km
You will find detailed information about
operating, maintaining and caring for your
vehicle in the "Operation" section. If you treat the engine with sufficient care
from the very start, it will reward you with
excellent performance for a very long peri-
od afterwards.
! You should therefore drive at varying
road and engine speeds for the first
1,50 0km.
! Avoid heavy loads during this time, e.g.
driving at full throttle. Do not exceed
2
/ 3 of the permissible maximum engine
speed for each gear (red area in the rev
cou nter).
! Change gea rin good time.
! Donot change down a gea rmanua lly in
order to brake.
Ve hic les wit hau tomatic transmission*
! Only use rang es 3,2or 1for slow driv-
ing, e.g. in mountainous terrain.
! It is best to use drive program Cfor
comfort mode. Vehicles wit
hautomatic transmission*
! Tryt o avoid depressing the accelerator
pedal beyond the pressure point (kick-
down).
After 1,500 km you may gradually bring
the veh icle up to full road and engine
speeds.
Additional driving tips for AM Gveh icles
! Do not exceed 140 km /hduring the
first 1,500 km.
! Only bring the engine up to the maxi-
mum engine speed of 4,50 0rpm for
sh ort periods.
i Theseguidelines also apply if a new engine
or rear-axle differential has bee nfitted to your
vehicle. Th

Operation
Engine compartment
There is no need for you to check the oil
level in the autom atictransmission. In the
event of oil loss or problems with gear
shifts, have the automatic tr ansmiss ion
checked at a qualified specialist workshop,
e.g. at a Mercedes-Benz Service Centre.
Coolant is a mixture of water, antifreeze
and corrosion inhibitor. Only check the
coolant level when the vehicle is standing
on a level surface and the engine has
cooled down.
The expansion tank is located in the engine
compartment on the right-hand side when
vi ewed inthe direction of travel. 1

6 Slowly unscrew the cap by about one
half turn and allow exc esspr essure to
escape.
6 Then continue to unscrew the cap and
rem ove it.
6 The coolant level is correct if:
! when the coolant is cold, it reaches
the mark inthe expansion tank filler
neck
! when the coolant is hot, it reaches
approximately 1.5 cm higher 6
Top up the coolant in the filler neck if
necessary.
6 Rep lace th e cap by tur ningitt o the
