General notes
G WARNING
If the engine spee disa bove the idling speed
and you engage transmission position D or R ,
the vehicl ec ould pul la wa ys uddenly .T here is
ar isk of an accident.
When engaging transmission position D or R ,
alway sf irmly depress the brake peda la nd do
not simultaneously accelerate. ! Change gea ring ood time and avoi ds pin-
ning the wheels. You could otherwise damage
the vehicle.
Depress the accelerator carefully when pulling
away.
The vehicl el ocks centrally once you have pulled
away. The locking knobs in the doors drop down.
You can open the doors from the insid eata ny
time.
You can als od eactivate the automatic locking
feature ( Y

It is only possible to shift the transmission from
position P to the desired position if you depress
the brake pedal. Only then is the shift lock
released.
i Upshifts take place at highe re ngine speeds
after ac old start. This help st he catalytic con-
verter to reach its operating temperature
more quickly.

Hill start assist Hill start assist help sy ou when pulling awa yf or-
ward sorinr everse on an uphill gradient. It holds
the vehicl ef or as hort time after you have
removed you rf oot from the brake pedal. This
gives you enoug ht ime to move you rf oot from
the brake peda ltot he accelerator peda la nd to
depress it before the vehicl eb egins to roll.
G WARNING
After as hort time, hill start assist wil lnol on-

There is ar isk of an accident and injury.
Therefore, quickly move you rf oot from the

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 include dint he ECO dis-
play.
An economical driving style specially requires
driving at moderate engine speeds.
Achieving ah igher valu eint he categories
"Acceleration" and "Constant": R
observe the gearshift recommendations. R
drive the vehicle in drive program C or E .
On long journeys at ac onstant 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 area satt he start of aj ourney. On lon-
ger journeys, there are fewer changes. For more
marked changes, perform am anua lr est

Braking
Important safety notes
G WARNING
If you shift down on as lippery road surface in
an attempt to increase the engine's braking
effect, the drive wheel sc ould lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on as lippery road surface.
Downhill gradients
! On long, steep gradients, you must reduce
the load on the brakes. To use engine braking,
shift to al owe rg ear in good time. This helps
you to avoid overheating the brakes and wear-
ing them out excessively. When making use of the engine braking
effect, it is possible that ad rive wheel may not
turn for some time, e.g. in the case of sud-
denly changing or slippery road surface con-
ditions. This could cause damage to the drive
train. This type of damage is not covered by
the Mercedes-Benz warranty.
Change into al owe rg ear in good time on long
and steep downhill gradients. This is especially
important if the vehicle is laden.
This also applies if you have activated cruise
control or Distance Pilo tD ISTRONIC.
Heavy and light loads
G WARNING
If you rest you rf oot on the brake peda lw hile
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail .T here is a
risk of an accident.
Never use the brake peda lasaf ootrest. Never
depres st he brake peda la nd the accelerator
peda latt he same time.
! Depressing the brake peda lc onstantly
results in excessive and premature wea rt o
the brake pads.
If the brakes have been subjected to ah eavy
load ,don ot stop the vehicle immediately ,b ut
drive on for as hort while. This allows the airflow
to cool the brakes more quickly.
Wet roads If you have driven for al ong time in heavy rain
withou tb raking, there may be ad elayed 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 then have to depres st he brake peda lm ore
firmly .M aintai nag reater distance from the
vehicle in front.
After driving on aw et road or having the vehicle
washed, brake firmly whil ep aying attention to
the traffic conditions. This wil lw arm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.136
