190 Running-in notes
The first 1,500 km
If you treat the engine with sufficient care
from the very start, it will reward you with
excellent performance for a very long period
afterwards.
R You should therefore drive at varying road
and engine speeds for the first 1,500 km
.
R Avoid heavy loads, e.g. driving at full throt-
tle, during this time. Do not exceed 2
/ 3 of
the maximum permissible engine speed for
each gear.
R Change gear in good time.
R Do not shift down a gear manually in order
to brake.
R Try to avoid depressing the accelerator
pedal beyond the pressure point (kick-
down).
R Only use ranges 3, 2 or 1 for slow driving,
e.g. in mountainous terrain.
After 1,500 km you may gradually bring the
vehicle up to full road and engine speeds.
Additional driving tips for AMG vehicles: R
Do not drive faster than
140 km/h for the
first 1,500 km.
R Only bring the engine up to a maximum
speed of 4,500 rpm for a brief period.
i You should also observe these notes if the
engine or rear axle transmission on your
vehicle has been replaced. AMG vehicles with a rear axle differ-
ential lock*
Your vehicle is equipped with a self-locking
differential

on the rear axle. To better protect
the differential gear on the rear axle, you
should perform an oil change after a running-
in phase of 3,000 km. This oil change will
increase the service life of your differential.
Have the oil change performed at a qualified
specialist workshop. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. Refuelling
Refuelling
G
Risk of explosion
Fuel is highly flammable. Fire, naked flames
and
smoking are therefore prohibited when
handling fuels.
Before refuelling, turn off the engine and
the auxiliary heating*. G
Risk of injury
Avoid any contact with fuels.
You can damage your health if your skin
comes

into direct contact with fuel or if you
inhale the vapour. G
Risk of fire
Do not use petrol to refuel vehicles with a
diesel
engine. Never mix diesel with petrol.
This would damage the fuel system and
engine and could result in a vehicle fire.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Even small
amounts of the wrong fuel will damage the
injection system. Damage resulting from
adding the wrong fuel is not covered by the
warranty. Operation

level when next
refuelling The engine oil level has dropped to a crit-
ical level. X
Check the engine oil level (Y page 195) and top
up the engine oil if necessary.
X Have the engine checked for leaks if the engine
oil needs topping up more often than usual. ± Display malfunc-

Troubleshooting
257Automatic transmission
Problem Possible cause/consequence Suggested solutions
The transmission has problems
shifting gear The transmission is losing oil. X
Have the transmission checked at a qualified specialist workshop
immediately. The acceleration ability is deteri-
orating.
The transmission no longer
changes gear. The transmission is in emergency
mode.
It is only possible to shift into
2nd gear and reverse gear. X
Stop the vehicle.
X Move the selector lever to P.
X Turn the key to position 0 in the ignition lock.
X Wait at least 10 seconds before restarting the engine.
X Move the selector lever to position D or R.
If D
is selected, the transmission shifts into 2nd gear; if R is selec-
ted, the transmission shifts into reverse gear.
X Have the transmission checked at a qualified specialist workshop
immediately. Practical advice

R

R SAE classification (viscosity)
is not available, you can use another min-
eral
or synthetic engine oil which has been
approved by Mercedes-Benz. Mixing oils reduces the benefits of high-
grade engine oil.
! Do
not use lubricant additives, since they
lead to increased wear and damage to the
mechanical assemblies. The use of lubri- cant additives will result in a restriction of
your warranty.
! Engine oils for vehicles without a diesel
particle
filter may also be used temporarily
in vehicles with a diesel particle filter if the
engine oil listed is not available. You must
then have an oil change carried out as soon
as possible.

Brake fluid
Over a period of time, the brake fluid absorbs
moisture from the air; this lowers its boiling
point. G
Risk of accident
If the boiling point of the brake fluid is too
low,
vapour pockets may form in the brake
system when the brakes are applied hard
(e.g. when driving downhill). This would
impair braking efficiency. Have the brake fluid renewed every two
years with a brake fluid that has been
approved by Mercedes-Benz and have this
confirmed in the Service Booklet.
i There is usually a notice in the engine
compartment

to remind you when the next
brake fluid change is due. Windscreen washer system
The washer fluid reservoir holds approxi-
mately 4.5 litres; on vehicles with the head-
lamp cleaning system* it holds 7 litres.
The headlamp cleaning system*
and the
windscreen washer system are both supplied
from the washer fluid reservoir.
