Driving tips
Changing gear The automatic transmission shifts through the
individual gears automatically when it is in trans-
mission position [ . This automatic gear shift-
ing behavior is determined by: R
the selected drive program R
the position of the accelerator pedal R
the road speed
Accelerator pedal position Your style of driving influences how the auto-
matic transmission shifts gear: R
little throttle: early upshifts R
more throttle: late upshifts
Double-clutch function
When shifting down, the double-clutch function
is active regardless of the currently selected
drive program. The double-clutch function reduces load change reactions and is conducive
to a sporty driving style. The sound generated by
the double-clutch function depends on the drive
program selected.

If the maximum engine speed in the gear cur-
rently engaged is reached and you continue to
accelerate, the automatic transmission auto-
matically shifts up in order to prevent engine
damage (except Mercedes-AMG vehicles).
Mercedes-AMG vehicles: if the temporary
setting has been activated and you continue
to accelerate when the maximum engine
speed has been reached, the automatic trans-
mission automatically shifts up. If the perma-
nent setting is activated, the automatic trans-
mission does not shift up automatically even
when the engine limiting speed for the current
gear is reached. Observe the protection
against reaching the overrevving range on the
multifunction display. Always make sure that
the engine speed does not reach the red area
of the tachometer. X

Shift recommendation
The gearshift recommendations assist you in
adopting an economical driving style. The rec-
ommended gear is shown in the multifunction
display. X
When the corresponding gearshift recom-
mendation C appears in the multifunction
display of the instrument cluster, shift to rec-
ommended gear D .
Protection against reaching the over-
revving range (Mercedes-AMG vehicles)
! In manual mode, the automatic transmis-
sion does not shift up automatically even
when the engine limiting speed for the current
gear is reached. When the engine limiting
speed is reached, the fuel supply is cut to
prevent the engine from overrevving. Always
make sure that the engine speed does not
reach the red area of the tachometer. There is

into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following: R
Wash away fuel from skin immediately
using soap and water. R
If fuel comes into contact with your eyes,
immediately rinse them thoroughly with Refueling 155
Driving and parking Z

Parking
Important safety notes
G WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system or exhaust
gas flow. There is a risk of fire.
Park the vehicle so that no flammable mate-
rials come into contact with parts of the vehi-
cle which are hot. Take particular care not to
park on dry grassland or harvested grain
fields.
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.
! Always secure the vehicle correctly against
rolling away. Otherwise, the vehicle or its driv-
etrain could be damaged.
To ensure that the vehicle is secured against
rolling away unintentionally: R
the electric parking brake must be applied. R
the transmission must be in position ] and
the SmartKey must be removed from the igni-
tion lock. R
the front wheels must be turned towards the
curb on steep uphill or downhill gradients. R
the empty vehicle must be secured at the
front axle with a wheel chock or similar, for
example, on uphill or downhill gradients. R
on uphill or downhill gradients the laden vehi-
cle must also be secured at the rear axle, for
example with a wheel chock or similar object. Switching off the engine
Important safety notes
G WARNING
The automatic transmission switches to neu-
tral position N when you switch off the engine.
The vehicle may roll away. There is a risk of an
accident.
After switching off the engine, always switch
to parking position P . Prevent the parked vehi-
cle from rolling away by applying the parking
brake.
Vehicles with automatic transmission X
Apply the electric parking brake. X
Shift the transmission to position ] .X
With the SmartKey: turn the SmartKey to

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 using drive program E
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 226).
For further information on the ECO display, see
( Y
page 225).
Brakes
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 the engine's braking effect.
This helps you to avoid overheating the
brakes and wearing them out excessively. When you take advantage of engine braking, a
drive wheel may not turn 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 war-
ranty.
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.
Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt resi-
due may form on the brake discs and brake
pads. This can result in a significantly longer
braking distance. Driving tips 163
