X
Pull the left-hand steering wheel gearshift
paddle (Y page 210).
The automatic transmission shifts down to
the next gear.
i If you slow down or stop without shifting
down, the automatic transmission auto-
matically shifts down.
Kickdown
i Vehicles with an AMG engine: it is not
possible to use kickdown in manual drive
program M.
You can also use kickdown for maximum
acceleration in manual drive program M.
X Depress the accelerator pedal beyond the
pressure point.
The transmission shifts to a lower gear
depending on the engine speed.
X Shift back up once the desired speed is
reached.
i Vehicles without an AMG engine: if you
apply full throttle, the automatic transmis-
sion shifts up to the next gear at maximum
engine speed. This prevents the engine
from overrevving. 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, it can no longer show any display
messages.
You will not then be able to see information
about the vehicle status, such as speed, out-
side temperature, warning and indicator
lamps, display messages or the failure of sys-
tems. Handling characteristics may be affec-
ted. Adjust 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 left-hand side.
Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 120 †. 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
If the temperature is slightly above freezing,
the road may be icy, especially in wooded
areas or on bridges. If you do not adjust your
driving style, the vehicle may start to skid. For
this reason, you should always adjust your
driving style and speed to the weather condi-
tions.
Changes in the outside temperature are dis-
played after a short delay. 212

Activating/deactivating the heater
booster function* The heater booster function helps the engine
to reach its operating temperature faster dur-
ing its warm-up phase, as well as helping to
heat the vehicle interior faster. The heater
booster function switches on when outside
temperatures are low and the coolant tem-
perature is less than 70 †. You can also acti-
vate the heater booster manually.

X
Repeat the measurement after about five
minutes if the engine is at normal operating
temperature.
X Repeat the measurement after about
30 minutes if the engine is not at normal
operating temperature (if the engine was
only started briefly).
The following message appears if the engine
is running:
Engine oil level Not when engine on
X Switch off the engine and wait for five
minutes if the engine is at normal operating
temperature, or for about 30 minutes if the
engine is not at normal operating temper-
ature (if you had started the engine only
briefly), before measuring.
i If you wish to cancel the measurement,
press the %button on the multi-func-
tion steering wheel.
Using the oil dipstick 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. Example
X
Turn cap :anti-clockwise and remove.
X Top up with the amount of oil required .
i The difference in quantity between the
minimum mark and maximum mark is
approximately 2 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 . Coolant
Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down. 294

X
Turn the key to position 2(Y page 182) 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.
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 Top up the coolant if necessary.
X Replace cap :and tighten all the way to
the stop.
For further information on coolant, see . 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
Windscreen washer fluid is highly flammable.
Fire, naked flames and smoking are prohibi-
ted when handling washer fluid concentrate.
! Only use windscreen washer fluid which
is suitable for plastic lamp lenses. Unsuit-
able windscreen washer fluid could dam-
age the plastic lamp lenses of the head-
lamps.
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. Engine compartment

X Solutions 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
