i An economical driving style involves driv-
ing at a moderate engine speed.
To achieve a higher value in the categories

observe the gearshift recommendation.

i On long journeys at a constant speed, e.g.
on the motorway, only the bar for

will change.
i The ECO display summarises the driving
characteristics from the start of the journey
to its completion. Therefore, there are
dynamic changes in the bars at the start of
a journey. During a prolonged driving time,
these changes are smaller. For more
dynamic changes, perform a manual reset.

Important safety notes
G
WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients
Do not depress the brake pedal continuously
while the vehicle is in motion, e.g. never
cause the brakes to rub by constantly apply-
ing light pressure to the pedal. This results in
excessive and premature wear to the brake
pads.
Change into a lower gear in good time on long
and steep downhill gradients.
Take particular note of this when driving a
laden vehicle and when towing a trailer.
i This also applies if you have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to maintain
vehicle speed. This relieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly.
Heavy and light loads
G
WARNING
The braking system can overheat if you leave
your foot on the brake pedal while driving.
This increases the braking distance and could
even cause the braking system to fail. There
is a risk of an accident.
Never use the brake pedal as a footrest. Do
not simultaneously depress both the brake
pedal and the accelerator pedal while driving.
