Manual drive program
General information
In manual drive program M, you can change
gear yourself by using the steering wheel pad- dle shifters. For this, the transmission must
be in position D. The gear currently selected
and engaged is shown in the multifunctiondisplay.
Manual drive program Mdiffers from drive
programs Eand Swith regard to spontaneity,
responsiveness and smoothness of gear
changes.

Manual drive program Mis temporarily
active. Depending on which paddle shifter
is pulled, the automatic transmission
immediately shifts into the next gear down
or up.
When manual drive program Mis activated via
the steering wheel paddle shifters, the tem-
porarily active manual drive program Mwill be
deactivated automatically after a limited
time, if the driving situation permits. In this
case, the automatic transmission shifts into
the automatic drive program that was last
engaged, i.e. Eor S. When driving on downhill
gradients, the temporarily active manual
drive program Mwill only be deactivated if the
accelerator pedal is depressed while the vehi- cle is rolling downhill.
Upshifting

Shift recommendation
The gearshift recommendations assist you inadopting an economical driving style. The rec-
ommended gear is shown in the multifunction display.
X Shift to recommended gear ;according
to gearshift recommendation :when
shown in the multifunction display of the
instrument cluster.
Downshifting
X Pull the left-hand steering wheel paddle
shifter ( Ypage 147).
The automatic transmission shifts down to
the next gear.
If you slow down or stop without shifting
down, the automatic transmission automati-
cally shifts down.
For maximum acceleration, pull the left-hand
steering wheel paddle shifter until the trans-
mission selects the optimum gear for the cur- rent speed.
If the engine exceeds the maximum engine
speed when shifting down, the automatic
transmission protects against engine damage
by not shifting down.
Kickdown
You can also use kickdown for maximum
acceleration in manual drive program M.
X Depress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to a
lower gear depending on the engine speed.
X Shift back up once the desired speed isreached. During kickdown, you cannot shift gears
using the steering wheel paddle shifters.
If you apply full throttle, the automatic trans-
mission shifts up to the next gear when the
maximum engine speed is reached. This pre-
vents the engine from overrevving.
Switching off the manual drive program
X Press the program selector button (Y page 147) repeatedly until Eor S
appears in the multifunction display.
Deactivating the temporary manual drive program
X Pull and hold the right-hand steering wheel
paddle shifter until the automatic transmis- sion shifts into the last active automatic
drive program: Eor S.
If manual drive program Mis deactivated, the
automatic transmission in automatic driveprogram Eor Smay shift from the current
gear into a higher or lower gear. This is
dependent on the position of the accelerator
pedal, speed and load.

Driving tips
General notes
Important safety notes
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If you operate mobile communication equip-
ment while driving, you will be distracted from traffic conditions. You could also lose controlof the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicleis stationary.
Observe the legal requirements for the coun- try in which you are driving. Some jurisdic-
tions prohibit the driver from using a mobile
phone while driving a vehicle.
If you make a call while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pull over to a safe location and stop
before operating the telephone.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers
a distance of 44 ft (approximately 14 m) per
se cond.
Driving tips155
Driving and parking

Apart from driving style, consumption is
dependent on many factors such as, e.g.: Rload
R tire pressure
R cold start
R choice of route
R electrical consumers switched on
These factors are not included in the ECO dis-
play.
The evaluation of your driving style is carried
out using the following three categories:
R
Acceleration(evaluation of all accelera-
tion processes):
- The bar fills up: moderate acceleration,
especially at higher speeds
- The bar empties: sporty acceleration
R
Constant(assessment of driving behavior
at all times)
- The bar fills up: constant speed and
avoidance of unnecessary acceleration
and deceleration
- The bar empties: fluctuations in speed
R
Coasting(assessment of all deceleration
processes) - The bar fills up: anticipatory driving,
keeping your distance and early release
of the accelerator. The vehicle can coast
without use of the brakes.
- The bar empties: frequent braking
An economical driving style specially requires
driving at moderate engine speeds.
To achieve a higher value in the categories
AccelerationandConstant:
R observe the gearshift recommendations.
R drive in drive program E.
On long journeys at a constant speed, e.g. on
the highway, only the bar for
Constantwill
change.
The ECO display summarizes the driving char- acteristics from the start of the journey to its completion. For this reason, the bars change
dynamically at the beginning of the journey.
On longer journeys, there are fewer changes. For more dynamic changes, carry out a man-
ual reset.
For further information on the ECO display,
see ( Ypage 196).
Braking
Important safety notes
GWARNING
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. For this, you need to have selected
manual drive program M. This helps you to
avoid overheating the brakes and wearing
them out excessively.
When you take advantage of the engine's
braking effect, a drive wheel may not turn
for some time, e.g. on a slippery road sur-
face. This could cause damage to the drive train. This type of damage is not covered bythe Mercedes-Benz warranty.
Briefly depressing the accelerator pedal on
downhill gradients while the manual drive
program Mis temporarily activated: the auto-
matic transmission may switch to the last
active automatic drive program Eor S. The
automatic transmission may shift to a higher
gear. This can reduce the engine's braking
effect.
