apetrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is
amalfunction in the engine electronics or in amechanical
componentoft he engine management system.
X Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it.
X Have the cause rectified immediately at aqualified specialist
workshop. The coolant tempera-
ture display is showing
more than 120 †. The
coolant warning lamp
may also be on and a
warning tone may
sound. The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant to
cool down.
X Check the coolant level (Y page 382). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct,t
he engine radiator fan may be faulty.
The coolant is too hot and the engine is no longer being cooled
sufficiently.
X If the coolant temperature is below 120 †, you can continue
driving to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving in
mountainous terrain and stop-start traffic. Manual transmission
Gear lever
! Only engage gear when the clutch pedal is
depressed.
! When shifting between
5thand 6thgear,
you should always push the gear lever all
the way to the right. Otherwise, you could
shift unintentionally into 3rdor4th gear
and damage the transmission.
If you shift down at too high aspeed (trans-
mission braking), this can cause the engine to overrev, leading to engine damage.
Do not use the clutch bite point to keep the
vehicle stationary on uphill gradients.
There is otherwise arisk of damaging the
clutch.
! On long and steep downhill gradients,
especially if the vehicle is laden or towing a trailer, you must shift into gear
1, 2or3in
good time. This uses the engine's braking
effect.T his relieves the load on the brake
system and preventst he brakes from over-
heating and wearing too quickly. k

Additives
!
Do not use any additives with the engine
oil.T his coul ddamage the engine.
Engine oil viscosity Viscosity describes the flow characteristics
of afluid. If an engine oil has ahigh viscosity
rating, it flow sslowly;t he lower the viscosity,
the faster it flows.
Engine oil selection is based on the respective outside temperatures and in accordance with
the SAE classification (viscosity) .The table
show syou which SAE classifications are to be
used. The low-temperature properties of
engine oilsc an be significantly impaired dur-
ing operation due to, for example, ageing or
soot and fuel accretion. It is therefore
strongly recommende dtoobserve regular oil
changes using an approved engine oil with the
appropriate SAE classification. Brake fluid
G
WARNING
The brake flui dcontinuously absorbs mois-
ture from the air. This results in the boiling
point of the brake flui dlowering. If the boiling
point of the brake flui distoo low,v apour
pockets may form when the brakes are sub-
jected to aheavy load. This would impair brak-
ing efficiency. There is arisk of an accident.
Have the brake flui drenewe datthe prescri-
bed intervals.
Comply with the important safety notes for
service products when handling brake fluid
(Y page4 73).
The brake flui dchange interval scan be found
in the Service Booklet.
Only use brake flui dapproved by Mercedes-
Benz according to MB Approva l331.0.

for the following:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
If antifreeze/corrosio ninhibitor is present in
the correct concentration, the boiling point of
the coolant during operation will be approx-
imately 130 †.
The antifreeze/corrosio ninhibitor concentra-
tion in the engine cooling system should:
R be at least 50% .Thisw illp rotect the engine
cooling system against freezing dow nto
approximately -37 †.
R not excee d55% (antifreeze protection
