2014 MERCEDES-BENZ SLS AMG GT ROADSTER fuel

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

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

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
0043and yellow segment 0044
light up in succession from left to right.
When red segments 0087light 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
0087light up briefly. AMG button (SETUP)
