stretches Derestricting the shift range/shifting
up
X
Pull the right steering wheel paddle (UP).
The shift range is derestricted. If you are
driving in manual drive program M, the
transmission shifts up to the next gear.
Restricting the shift range/shifting
down X
Pull the left steering wheel paddle (DOWN).
The transmission shifts down one gear and
restricts the shift range to this gear.
If the engine speed in manual drive
program Mis too high, it is not possible to
shift down. If you pull the left-hand steering
wheel paddle shifter (DOWN)
(Y page 124), the two red segments in the
instrument cluster flash.
Clearing the shift range restriction X
Pull the right-hand steering wheel paddle
shifter (UP) until the number for the gear
disappears from the multifunction display.
or
X Use the E-SELECT lever to shift the
transmission to position D.
The transmission shifts from the current
shift range directly to D. 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
i GT model: in manual drive program M,
the transmission shift and response times
are 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 121). 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. AMG SPEEDSHIFT DCT 7-speed sports transmission

Fuel consumption also increases when
driving in cold weather, in stop-start traffic
and in hilly terrain.
Drinking and driving G
WARNING
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment.
The possibility of a serious or even fatal
accident are greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Emission control G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with
the manufacturer's specifications. For this
reason, all work on the engine must be carried
out by qualified and authorized Mercedes-
Benz technicians.
The engine settings must not be changed
under any circumstances. Furthermore, all
specific service work must be carried out at
regular intervals and in accordance with the
Mercedes-Benz service requirements. Details
can be found in the Maintenance Booklet. 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
braking on a slippery road surface.
Downhill gradients !
On long and steep gradients, you must
reduce the load on the brakes by shifting
early to a lower gear. This allows you to take
advantage of the engine braking effect and
helps avoid overheating and excessive
wear of the brakes.
When you take advantage of the engine
braking effect, 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 warranty.
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. Driving tips

such as carbon monoxide (CO) may enter the
vehicle. This is the case, e.g. if the vehicle
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.
Observe the notes in the "Winter operation"
section (Y page 250).
Summer tires Observe the notes in the "Winter operation"
section (Y
page 250).
Slippery road surfaces 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.
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
freezing point.

For more information on driving with
snow chains, see (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 122). 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 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 134
