following:
R comfort-oriented engine and transmission
settings
R optimal fuel consumption resulting from
the transmission shifting up sooner
R the vehicle pulling away more gently in
forward and reverse gears, unless the
accelerator pedal is depressed fully
R increased sensitivity. This improves driving
stability on slippery road surfaces, for
example
R the transmission shifting up sooner; This
results in the vehicle being driven at lower
engine speeds and the wheels being less
likely to spin
Drive programs Sand S+are characterized
by the following:
R sporty engine and transmission settings
R the transmission shifting up later and
shifting down dynamically
R as a result of the later transmission
upshifts, the fuel consumption may be
higher
R if a period of dynamic driving is followed by
an extended phase with a constant
accelerator pedal position, the vehicle 126

shifts up to a higher gear. This optimizes
fuel consumption
If a gentle driving style is adopted in
automatic drive programs C/S/S+, the drive
program settings are adjusted to optimize
fuel consumption. Depending on the
operating conditions, the transmission shifts
to a higher gear. Shift ranges
Introduction In certain driving situations, it is
recommended that you restrict the shift
range. The set shift range appears in the
instrument cluster's multifunction display
(Y page 123). The transmission only shifts to
the gear displayed in the instrument cluster.
When the maximum engine speed is reached,
the transmission shifts up a gear in the
automatic programs C/S/S+. Gear
restriction is correspondingly increased by
one gear. Driving situation

Selecting the ideal shift range X
Pull the left-hand steering wheel paddle
shifter repeatedly until the function is
activated.
Depending on the selected drive program,
the transmission shifts to a gear which
allows ideal acceleration and deceleration.
To do this, the transmission shifts down
one or more gears. Manual drive program

significantly shorter with sportier and more
aggressive gear changes.
In manual drive program M, you need to
change gear yourself using the steering wheel
paddle shifters (Y page 125). The
transmission only shifts down automatically
at low engine speeds depending on the
respective gear.
! In manual drive program M, the
transmission 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 and observe
the upshift indicator. There is otherwise a
risk of engine damage.
X To activate the manual drive program:
turn the drive program selector switch until
M appears in the instrument cluster's
multifunction display.
M lights up in red on the drive program
selector switch.
X To deactivate the manual drive
program: turn the drive program selector
switch and select another drive program.
Upshift indicator The upshift indicator is a four-stage display
designed to assist you in sporty driving. The upshift indicator allows you to recognize
the ideal shift point for dynamic acceleration. White segments

When red segments =light up and the "up"
message appears in the multifunction
display, the ideal shift point has been
reached:
X Shift up using the right-hand steering wheel
paddle shifter (UP) as quickly as possible.
The vehicle shifts up to the next gear.
i If you continue to increase the engine
speed without shifting up in time, the fuel
supply is shut off to protect the engine. This
results in abruptly reduced acceleration.
Display for downshift override You cannot shift down with the left steering
wheel paddle shifter if the engine speed is too
high due to a downshift. If you then pull the
left steering wheel paddle shifter, both red
segments

133Driving and parking Z

AMG high-performance composite
brake system The AMG high-performance compound brake
system and the AMG ceramic high-
performance compound brake system are
designed for high loads. This may lead to
noise when braking. This will depend on:
R Speed
R Braking force
R Environmental conditions, such as
temperature and humidity
The wear of individual components of the
brake system, such as the brake pads/linings
or brake discs, depends on the individual
driving style and operating conditions.
For this reason, it is impossible to state a
mileage that will be valid under all
circumstances. An aggressive driving style
will lead to high wear. You can obtain further
information about this from your authorized
Mercedes-Benz Center.
New and replaced brake pads and discs only
reach their optimum braking effect after
several hundred kilometers of driving.
Compensate for this by applying greater force
to the brake pedal. Keep this in mind, and
adapt your driving and braking accordingly
during this break-in period.
Excessive heavy braking results in
correspondingly high brake wear. Observe
the brake wear warning lamp in the
instrument cluster and note any brake status
messages in the multifunction display.
Especially for high performance driving, it is
important to maintain and have the brake
system checked regularly. Driving on wet roads
Hydroplaning If water has accumulated to a certain depth
on the road surface, there is a danger of
hydroplaning occurring, even if:
R
you drive at low speeds.
R the tires have adequate tread depth.
For this reason, in the event of heavy rain or
in conditions in which hydroplaning may
occur, you must drive in the following
manner:
R lower your speed.
R avoid ruts.
R brake carefully.
Driving on flooded roads !
Do not drive through flooded areas.
Check the depth of any water before driving
through it. Drive slowly through standing
water. Otherwise, water may enter the
vehicle interior or the engine compartment.
This can damage the electronic
components in the engine or the automatic
transmission. Water can also be drawn in
by the engine's air suction nozzles and this
can cause engine damage. Winter driving
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
braking on a slippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the
vehicle. This is the case, e.g. if the vehicle Driving tips
137Driving and pa rking
Z

becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open
a window on the side of the vehicle that is not
facing into the wind.
At the onset of winter, have your vehicle
winterized at a qualified specialist workshop,
e.g. at an authorized Mercedes-Benz Center.
Drive particularly carefully on slippery road
surfaces. Avoid sudden acceleration, steering
and braking maneuvers. Do not use cruise
control.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Shift the transmission to position N.
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Changes in the outside temperature are
displayed after a short delay.
Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges. You
should pay special attention to road
conditions when temperatures are around
the freezing point.
For more information on driving with snow
chains, see (Y page 251).
For more information on driving with summer
tires, see (Y page 250).
Observe the notes in the "Winter operation"
section (Y page 250). Driving systems
Cruise control
Important safety notes Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed.
On long and steep downhill gradients,
especially if the vehicle is laden, you must
select shift range
1,2or 3in good time
(Y page 127). By doing so, you will make use
of the braking effect of the engine. This
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly.
If you fail to adapt your driving style, cruise
control can neither reduce the risk of an
accident nor override the laws of physics.
Cruise control cannot take into account the
road, traffic and weather conditions. Cruise
control is only an aid. You are responsible for
the distance to the vehicle in front, for vehicle
speed, for braking in good time and for
staying in your lane.
Use cruise control only if road and traffic
conditions make it appropriate to maintain a
steady speed for a prolonged period. You can
set any road speed above 20 mph
(30 km/h).
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintain a constant speed e.g.
in heavy traffic or on winding roads
R on slippery road surfaces. Braking or
accelerating could cause the drive wheels
to lose traction and the vehicle could then
skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is a change of drivers, advise the new
driver of the speed stored. 138
