display.
X When the corresponding gearshift recom-
mendation 0043appears in the multifunction
display of the instrument cluster, shift to rec-
ommended gear 0044.
Display for shift override If the engine speed becomes too high or too low
as a result of shifting gear, you cannot shift gear
using the steering wheel paddle shifters. If you
then pull the left-hand or right-hand steering
wheel paddle shifter, segments 0043light up red
briefly.
Downshifting X
Pull the left-hand steering wheel paddle
shifter (Y page 121).
In cases where it is permissible, the automatic transmission shifts down to the next gear.
X Maximum acceleration: pull the left-hand
steering wheel paddle shifter until the trans-
mission selects the optimum gear for the cur- rent speed.
If you slow down or stop without shifting down,
the automatic transmission automatically shifts down.
Deactivating X
Press the M button (Y page 121).
The indicator lamp in the button goes out.
RACE drive program (AMG GT C Road-
ster) The RACE drive program is designed for maxi-
mum performance in terms of shift points and engine speeds. The engine and transmission
should be at normal operating temperature for
the RACE drive program (Y page 170). Use the
RACE drive program on a closed-off race circuit.
The RACE drive program is characterized by the
following:
R the vehicle exhibits driving characteristics
suitable for the racetrack.
R all vehicle systems are set for maximum
sportiness.
R for optimum performance, the transmission
shifts up later and shifts down sooner.
R the multifunction display shows the manual
gearshift program without upshift indicator
(Y page 122).
R the gearshift recommendation gives you
information for slowly warming up the drive
assemblies and for adopting a fuel-efficient
driving style (Y page 123). You can follow the
gearshift recommendations at all times and
shift gear accordingly using the steering
wheel paddle shifters. On the basis of the
gearshift recommendation, using the steering wheel paddle shifters, you can optimize the
drive train and engine operating mode at any
time.
R if you have selected a gear manually, this will
be maintained until the vehicle speed increa-
ses or decreases dramatically.
R if you do not follow the gearshift recommen-
dations, the automatic shift points may result
in high fuel consumption.
R the suspension exhibits particularly hard
springing and damping settings.
R the transmission shift and response times are
significantly shorter with more aggressive
gear changes. This is particularly the case
when shifting up. The shift strategy is thus
designed to interact dynamically with the
high-revving engine.
R gliding mode is not available.
R the ECO start/stop function is not available. 124

Trickle charging the on-board electrical
system battery The battery may drain if the vehicle is left sta-
tionary for long periods. In this case, Mercedes-
Benz recommends attaching the trickle charger to 12 V socket 0043in the trunk.
i A trickle charger and further information
can be obtained from a qualified specialist
workshop.
X Switch the ignition off.
X Open the trunk lid. 130
ParkingDriving and parking

X
Connect the cable provided in the trunk to the
trickle charger.
X Connect the trickle charger to 12 V socket 0043.
Consult the manufacturer's operating instruc- tions on how to do so.
The trunk lid can be closed, even if a trickle
charger is connected. Make sure that the con-
nector for both the connector cables is outside
of the vehicle.
The connector can then separate if the vehicle is moved, even if you forget to disconnect the con-
nector cables. This prevents damaging the
cables and the trickle charger.
A trickle charger connected to 12 V socket 0043
only maintains the current charge level of the
vehicle's electrical system battery. If the vehi-
cle's electrical system battery is discharged, it
needs to be charged with a battery charger. Driving tips

Important safety notes G
WARNING
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. G
WARNING
If you operate mobile communication equip-
ment when driving, you may be distracted
from the traffic situation. You could also lose
control of the vehicle. There is a risk of an
accident.
Only operate this equipment when the vehicle is stationary.
Observe the legal requirements for the country
in which you are driving. Some jurisdictions pro-
hibit 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 sec-
ond.
Drive sensibly – save fuel Observe the following tips to save fuel:
X The tires should always be inflated to the rec-
ommended tire pressure.
X Remove unnecessary loads.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all service and maintenance work car-
ried out at the specified intervals.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic and in hilly ter- rain.
