Risk of accident
Only remove the key from the ignition lock
when the vehicle is stationary, as you can-
not steer the vehicle with the key removed.
Never leave children unsupervised in the
vehicle. 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. Parking brake 1

Risk of accident
If the engine is not running, there is no
power assistance for the steering and
brakes. Steering and braking will then
require significantly greater effort.
As a result, you might lose control of the
vehicle, cause an accident and injure your-
self and others.
Do not switch off the engine while driving.

Notes on the transmission
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 floormats or carpets are correctly
secured and that there is sufficient clear-
ance for the pedals. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This
could cause the drive wheels to lose their
grip and the vehicle could skid. This could
cause you to lose control of your vehicle
and cause an accident. Controls

When shifting between 5thand 6thgear,
you should always push the gear lever all
the way to the right. Otherwise, you could
shift unintentionally into thirdorfourth
gear and damage the transmission.
Do not exceed the maximum speed for the
individual gears.
If you shift down at too high a speed (trans-
mission braking), this can cause the engine
to overrev, leading to engine damage.

braking will be required to prevent the vehi-
cle from gaining speed. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly.

cle is stationary, otherwise the transmis-
sion could be damaged.

Shift up or down a gear when the corre-
sponding indicator appears in the instru-
ment cluster's multi-function display.
The shift indicator is meant as a recommen-
dation for an economical driving style. How-
ever, always observe traffic conditions, as
your driving style is determined, in the first
instance, by the traffic situation. AUTOTRONIC* (continuously variable
automatic transmission)
AUTOTRONIC is an electronically controlled,
continuously variable automatic transmis-
sion. The transmission ratio is changed con-
tinuously. This enables it to be ideally adapted
to your individual driving styles and to provide
increased driving comfort. Controls

Risk of accident
No further messages can be displayed if the
instrument cluster and/or the multi-func-
tion display fails.
This means that you will not see information
about the driving situation, such as the
speed, outside temperature, warning/indi-
cator lamps, display messages or system
failures. The vehicle's handling character-
istics may be affected. Adjust your driving
style and speed accordingly.
Immediately consult a qualified specialist
workshop which has the necessary special-
ist knowledge and tools to carry out the
work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz
Service Centre for this purpose. In particu-
lar, work relevant to safety or on safety-
related systems must be carried out at a
qualified specialist workshop. Cont
