Risk of accident
Do not put any objects in the driver's footwell.
If you use a floormat or carpet in the driver's
footwell, make sure that they are correctly
secured and that there is sufficient clearance
for the pedals.
Do not place several floormats on top of one
another.
Otherwise, the objects or floormats could get
between the pedals in the event of sudden
braking or acceleration. You may then no lon-
ger be able to brake, change gear or acceler-
ate as intended. This may result in an accident
and injury. G
Risk of poisoning
Never leave the engine running in enclosed
spaces. The exhaust gases contain carbon
monoxide. Inhaling exhaust fumes consti-
tutes a health hazard and could lead to loss
of consciousness or even death.
! Do not depress the accelerator pedal
when starting the engine. Automatic transmission X

goes out, turn the key to position 3and
release it as soon as the engine is running.
i You can start the engine without preglow
if the engine is warm. Pulling away
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only shift into reverse gear when the vehi-
cle is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. Otherwise, you could damage the

The vehicle locks centrally once you have
pulled away. The locking knobs in the doors
drop down.
You can open the doors from the inside at
any time.
You can also deactivate the automatic lock-
ing feature (Y page 104).
i It is only possible to move the selector
lever to the desired position if you depress
the brake pedal. Only then is the selector
lever lock released.
X Depress the brake pedal and keep it
depressed.
X Move the selector lever to position Dor R.
X Release the parking brake (Y page 84).
X Release the brake pedal.
X Carefully depress the accelerator pedal.
i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill start assist Hill start assist helps you when pulling away
on uphill gradients. It holds the vehicle for a
short time after you have removed your foot
from the brake pedal. This gives you enough
time to move your foot from the brake pedal
to the accelerator pedal and depress it before
the vehicle begins to roll. G
Risk of accident
Never leave the vehicle when it is held by hill
start assist. After approximately one second,
hill start assist will no longer brake your vehi-
cle and it could roll away.
X Take your foot off the brake pedal.
i Once you have taken your foot off the
brake pedal, the vehicle is held for around
one second.
X Pull away. Hill start assist does not function if:
R
you are pulling away on a level road or a
downhill gradient.
R the selector lever is in position N.
R the vehicle is secured with the parking
brake.
R ESP ®
is malfunctioning. Parking
G
Risk of accident
Only remove the key from the ignition lock
when the vehicle is stationary, as you cannot
steer the vehicle with the key removed.
Never leave children unsupervised in the vehi-
cle. They could release the parking brake. This
could lead to a serious or fatal accident. G
Risk of fire
Make sure that the exhaust system does not
under any circumstances come into contact
with easily ignitable material such as dry grass
or petrol. The material could otherwise ignite
and set the vehicle on fire.

G
Risk of accident
The movement of the pedals must not be
impaired in any way. Do not keep any objects
in the driver's footwell. Make sure that floor-
mats or carpets are correctly secured and
that there is sufficient clearance for the ped-
als.
Do not place several floormats on top of one
another. G
Risk of accident

wheel* (12 buttons) (Y page 26)G
Risk of accident
No further messages can be displayed if the
instrument cluster and/or the multi-function
display fails.
This means that you will not see information
about the driving situation, such as the speed,
outside temperature, warning/indicator
lamps, display messages or system failures.
The vehicle's handling characteristics may be
affected. 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 gauge
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 †. 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 (vehi-
cles with 12-button luxury multi-func-
tion steering wheel*)
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. 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
When the temperature displayed is just above
freezing point, the road surface may be icy,
especially in wooded areas or on bridges. The
vehicle could skid if you fail to adapt your
driving style. Always adapt your driving style
and drive at a speed to suit the prevailing
weather conditions.
Changes in the outside temperature are dis-
played after a short delay. 90 Instrument clusterCont
