G WARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example: R
release the parking brake. R
shift the automatic transmission out of the
parking position P .R
start the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle. The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or there is a malfunction in
the system, it may not be possible to apply the
released parking brake. X
If this is the case, only park the vehicle on
level ground and secure it to prevent it rolling
away. X
Shift the automatic transmission to position
P .
It may not be possible to release an applied
parking brake if the on-board voltage is low or
there is a malfunction in the system. Contact a
qualified specialist workshop.
The electric parking brake performs a function
test at regular intervals while the engine is
switched off. The s ounds that can be heard while
th is is occurring are normal.

In addition to driving style, the actual consump-
tion is affected by other factors, such as: R
Load R
Tire pressure R
Cold start R
Choice of route R
Active electrical consumers
These factors are not included in the ECO dis-
play.
An economical driving style specially requires
driving at moderate engine speeds.
Achieving a higher value in the categories
"Acceleration" and "Constant": R
observe the gearshift recommendations. R
drive the vehicle in drive program C or E
(vehicles with a DYNAMIC SELECT button).
On long journeys at a constant speed, e.g. on the
highway, only the outer area for "constant" will
change.
The ECO display summarizes the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer areas at the start of a journey. On lon-
ger journeys, there are fewer changes. For more
marked changes, perform a manual rest
( Y
page 178).
For more information on the ECO display, see
( Y
page 177).
Braking
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.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients
! On long and steep gradients, you must
reduce the load on the brakes by shifting to a
lower gear in good time. This allows you to
take advantage of engine braking. For this you
must first activate manual gearshifting. This helps you to avoid overheating the brakes and
wearing them out excessively.
When you take advantage of engine braking, it
is possible that a drive wheel will not rotate for
some time, e.g. on a slippery road surface.
This could cause damage to the drive train.
This type of damage is not covered by the
Mercedes-Benz warranty.
Briefly depressing the accelerator pedal on
downhill gradients while the manual drive pro-
gram M is temporarily activated: the automatic
transmission may switch to the last active auto-
matic drive program E or S . The automatic trans-
mission may shift to a higher gear. This can
reduce the engine's braking effect.
Heavy and light loads
G WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately. Drive
on for a short while. This allows the airflow to
cool the brakes more quickly.
Wet roads If you have driven for a long time in heavy rain
without braking, there may be a delayed reac-
tion from the brakes when braking for the first
time. This may also occur after the vehicle has
been washed or driven through deep water.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehicle
washed, brake firmly while paying attention to
the traffic conditions. This will warm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion. Driving tips 145
