GWARNING
If engine oil comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is arisk of fire and injury.
Make sure that engine oil is not spilled next to
the filler neck. Let the engine cool downa nd
thoroughly clea nthe engine oil off the com-
ponents before starting the engine.
HEnvironmental note
When adding oil,t ake care not to spil lany. If
oil enters the soil or waterways, it is harmfu lto
the environment.
!Only use engine oilsa nd oil filters that have
been approved for vehicles with aservice sys-
tem. You can obtai nalist of the engine oils
and oil filters tested and approved in accord- ance with the Mercedes-Benz Specifications
for Service Products at any Mercedes-Benz
Service center.
Damag etothe engine or exhaust system is
caused by the following:
Rusing engine oilsa nd oil filters that have not
been specifically approved for the service
system
Rreplacing engine oil and oil filters after the
interval for replacement specified by the
service system has been exceeded
Rusing engine oil additives.
!Do not add too much oil.Ift he oil levelis
above the "max" mark on the dipstick, too
much oil has been added. This can lea dto
damage to the engine or the catalytic con-
verter. Have excess oil siphoned off.
Example :engine oil cap
XTurn cap :counter-clockwise and remove it.
XAdd engine oil.
If the oil leve lisatorbelow the MIN mark on
the oil dipstick, add 1.1 US qt (1.0 liter) of
engine oil.
XReplace cap :on the filler neck and turn
clockwise.
Ensure that the cap locks into place securely.
XCheck the oil leve lagain with the oil dipstick
(Ypag e232).

GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible,l et the engine cool downa nd
touch only the components described in the
following.
GWARNING
The cooling system is pressurized, particularly
when the motor is warm .Ifyou open the cap,
you coul dbescalded if hot coolant sprays out.
There is arisk of injury.
Let the engine cool downb efore you open the
cap. Wearg lovesand eye protection. Slowly
open the cap to relieve pressure.

Maintenance and care
Z

If standard unleaded gasoline is unavailable
and you have to refuel with unleaded gasoline
of alowerg rade,observe the following pre-
cautions:
ROnly fill the fuel tank to half full with regular unleaded gasoline and fill the rest with pre-
mium-grade unleaded gasoline as soon as
possible.
RDo not drive at the maximum speed.
RAvoid sudden acceleration and engine
speedso ver 3,000 rpm.
You wil lusuall yfind information abou tthe fuel
grade on the pump. If you cannot find the label
on the pump, ask the staff for assistance.
iFor further information, consult aqualified
specialist workshop or visit
http://www.mbusa.com (USA only).
As atemporary measure, if the recommended
fuel is not available, you may also use regular
unleaded gasoline with an octane rating of
87 AKI/91 RON. This may reduce engine per-
formance and increase fuel consumption. Avoid
driving at full throttle and sudden acceleration.
Never refuel using fuel with alowerA KI.
Information on refueling (
Ypage 130).
Additives in gasoline
!Operating the engine with fuel additives
adde dlater can leadtoe ngine failure. Do not
mix fuel additives with fuel. This does not
include additives for the removal and preven-
tion of residueb uildup. gasoline must only be
mixed with additives recommended by
Mercedes-Benz. Compl ywith the instructions
for use on the product label. More information
abou trecommended additives can be
obtained from any authorized Mercedes-Benz
Center.
Mercedes-Benz recommends that you use bran- ded fuels that have additives.
The fuel quality available in some countries may
not be sufficient. Residue could build up in the
fuel injection system as aresult. In such cases,
and in consultation with an authorized
Mercedes-Benz Center, the fuel may be mixed
with the cleaning additive recommended by
Mercedes-Benz. You must observe the notes
and mixing ratios specifiedont he container.

Brake fluid
GWARNING
The brake fluid constantly absorb smoisture
from the air. Thi slowers the boiling point of
the brake fluid .Ifthe boiling point of the brake
fluid is too low, vapor pockets may form in the
brake system when the brakes are applied
hard. Thi swould impai rbraking efficiency.

Comply with the important safety precautions
for service products whe nhandling coolant
(
Ypage 284).
The coolant is amixture of water and anti-
freeze/corrosion inhibitor. It is responsible for
the following:
RAnti-corrosion protection
RAntifreeze protection
RRaising the boiling point
If the coolant has antifreeze protection dow nto
-35 ‡(-37 †), the boiling point of the coolant
during operation is approximatel y266 ‡
(130 †).
