Downshifting
G
Risk of accident
Do not shift down to brake on a slippery road
surface. This could cause the drive wheels to
lose their grip, and the vehicle could skid.
X Pull the left-hand paddle ( Ypage 114).
The automatic transmission shifts down to
the next gear.
i For maximum acceleration, pull the left-
hand steering wheel gearshift paddle until
the transmission selects the optimum gear
for the current speed.
Kickdown
i On vehicles with AMG engines, it is not
possible to use kickdown in manual drive
program M. Instrument cluster
Points to remember
You will find an illustration of the instrument
cluster in the "At a glance" section
(Y page 27). G
Risk of accident
If the instrument cluster or the multi-function
display fails, then no display messages can be
shown.
You will not then be able to see information
about the vehicle status, such as speed and
outside temperature, warning and indicator
lamps, display messages or the failure of sys-
tems. The vehicle’s handling characteristics
may be affected. Adapt your driving style and
speed accordingly.
Immediately consult a qualified specialist
workshop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist workshop. Coolant temperature display
The coolant temperature gauge is in the
instrument cluster on the right-hand side.
Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 120 †. The coolant tem-
perature may rise to the top end of the scale
at high outside temperatures and on long
uphill stretches. Speedometer with segments
The segments in the speedometer indicate
which speed range is available.
Cruise control mode:
The segments light up from the stored speed
to the maximum speed.
Variable Speedtronic mode:
The segments light up from the start of the
scale to the selected limit speed.
Distronic Plus* mode:
One or two segments around the stored
speed light up. Rev counter
The red band in the rev counter indicates the
engine's overrevving range. The fuel supply is
interrupted to protect the engine when the
red band is reached.
! Do not drive in the overrevving range.
Doing so will damage the engine. Outside temperature display
G
Risk of accident
At temperatures just above freezing point, the
road could be icy, particularly in wooded areas
or on bridges. The vehicle could start skidding
if you fail to adapt your driving style. You
should therefore always adapt your driving
style and speed to suit the weather condi-
tions. Inst

E 300 (example)
X
Pull oil dipstick :out of the oil dipstick
tube.
X Wipe off oil dipstick :.
X Insert oil dipstick :into the oil dipstick
tube to the stop, and take it out again.
The oil level is correct if the level is between
the minimum mark =and maximum
mark ;.
X Top up the oil if necessary.
Topping up the engine oil H
Environmental note
When topping up the oil, take care not to spill
any. Oil must not be allowed to escape into
the soil or waterways. You would otherwise be
damaging the environment. Cap (example)
X
Turn cap :anti-clockwise and remove.
X Top up with the amount of oil required
(Y page 336). i
The difference in quantity between the
minimum mark and maximum mark is
approximately 2 litres.
i On vehicles with a 4-cylinder petrol
engine and vehicles with an 8-cylinder pet-
rol engine, the difference between the MIN
mark and the MAX mark is approximately
1.5 litres.
! Do not add too much oil. If too much oil
is added and the oil level is above the max-
imum mark on the dipstick, the engine or
catalytic converter could be damaged.
Have excess oil siphoned off.
X Replace cap :on the filler neck and
tighten clockwise.
Ensure that the cap locks into place
securely.
For further information on engine oil, see
(Y page 336). Coolant
Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down.
X Turn the key to position 2(Y page 75) in
the ignition lock.
X Check the coolant temperature gauge in
the instrument cluster. G
Risk of injury
The cooling system is pressurised. Therefore,
only unscrew the cap once the engine has
cooled down. The coolant temperature gauge
must display less than 70 †. Otherwise, you
could be scalded if hot coolant escapes. Engine compartment

The coolant expansion tank is located in the
engine compartment on the right when
viewed in the direction of travel. X
Slowly turn cap :half a turn anti-clock-
wise and allow excess pressure to escape.
X Turn cap :further anti-clockwise and
remove it.
There is sufficient coolant in expansion
tank ;if the coolant is level with marker
bar =in the filler neck when cold or
approximately 1.5 cm higher when hot.
X If necessary, top up with coolant which has
been tested and approved by Mercedes-
Benz.
X Replace cap :and tighten all the way to
the stop.
For further information on coolant, see
(Y page 338). Windscreen washer system/head-
lamp cleaning system*
The washer fluid reservoir for the windscreen
washer system and headlamp cleaning sys-
tem* is located in the engine compartment on the left-hand side when viewed in the
direction of travel. i
Add windscreen washer concentrate to
the washer fluid all year round. G
Risk of fire
Washer fluid concentrate is highly flammable.
Fire, naked flames and smoking are prohibi-
ted when washer fluid concentrate is being
handled.
! Only use washer fluid concentrate which
is suitable for plastic lenses. Unsuitable
washer fluid concentrate could damage the
plastic lenses of the headlamps.
X Mix the windscreen washer fluid in a con-
tainer beforehand.
X At temperatures above freezing:
Fill the washer fluid reservoir with a mix of
water and windscreen washer concentrate
(e.g. MB SummerFit).
X At temperatures below freezing:
Fill the washer fluid reservoir with a mix of
water, antifreeze additive and windscreen
washer concentrate (e.g. MB WinterFit).
Adapt the mixing ratio to the outside tem-
peratures.
X To open: pull cap:upwards by the tab.
X Top up with the premixed washer fluid.
X To close: press cap :onto the filler neck
until it engages. 222

The red coolant
warning lamp
comes on while
the engine is
running. A warn-
ing tone also
sounds. The coolant temperature has exceeded 130 †. The airflow to the
radiator may be blocked or the coolant level may be too low.

Problem
Possible causes/consequences and
X XSolutions Vehicles with a petrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is a malfunction in the engine electronics or a mechanical
component of the engine control unit.
X
Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at a qualified specialist
workshop.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. The coolant tempera-
ture gauge shows a
value above 120 †.
The coolant warning
lamp may also light up
and a warning tone may
sound (Y
page 117). 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 221). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct, the radiator fan may be faulty. The
coolant is too hot and the engine is no longer being cooled suffi-
ciently.
X
If the coolant temperature is less than 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 on
mountain roads and stop/start driving. 292
