Manual shift program (R 63 AMG only)
In addition to the automatic shift
programC orS, your vehicle is equipped
with the manual shift programM.
In the manual program modeM,
system-controlled automatic gearshifting
is switched off and you need to change the
gears by manually upshifting or downshift-
ing using the steering wheel gearshift
control buttons to the left and right of the
steering wheel (
page 207).

You can change the gears manually with
drive positionD selected. You can upshift
or downshift through the gears in succes-
sion.
!Allow engine to warm up under low load use.
Do not place full load on the engine until the
operating temperature has been reached.
Shift into reverse gearR or park positionP only
when the vehicle is stopped.
Avoid spinning of a drive wheel for an extended
period when driving off on slippery road
surfaces. This may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
iFor information on automatic program
modesC orS, see “Automatic shift program”
(
page 206) and “Steering wheel gearshift con-
trol” (

Upshifting
Briefly press right shift button2
(
page 207).
The transmission shifts to the next
higher gear.If you have selected the AMG menu in the
control system (
page 168) and you are
driving in the manual program modeM,
upshift indicator2 in the multifunction
display advises you to upshift before the
engine reaches the overspeed range. Thus
you can drive at the maximum engine
speed for each gear without overrevving
the engine.
1Gear indicator
2Upshift indicator
Shift to the next higher gear.
The fuel supply will otherwise be inter-
rupted to prevent the engine from over-
revving.Downshifting
Briefly press left shift button1
(
page 207).
The transmission shifts to the next
lower gear.
!In the manual program modeM, the trans-
mission will not upshift, even if the engine has
reached its overrevving range. Shift up to the
next gear before the engine has reached its over-
revving range. Make absolutely certain that the
engine speed does not reach the red marking on
the tachometer (
page 157). Otherwise the
engine could be damaged which is not covered
by the Mercedes-Benz Limited Warranty.
Warning!G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.
iWhen you brake or stop, the transmission
shifts down to a gear from which you can easily
accelerate or drive off.

Good visibility
Auto-dimming rear view mirrors*
The reflection brightness of the exterior
rear view mirror on the driver’s side and
the interior rear view mirror will respond
automatically to glare when
the ignition is switched on
and
incoming light from headlamps falls on
the sensor in the interior rear view
mirror
The rear view mirror will not react if
the automatic transmission is set to
positionR
the interior lighting is turned on
Warning!G
The auto-dimming function does not react if
incoming light is not aimed directly at sen-
sors in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, when transporting cargo
which covers the rear window.
Light hitting the mirror(s) at certain angles
(incident light) could blind you. As a result,
you may not be able to observe the traffic
conditions and could cause an accident.
Warning!G
In case of an accident liquid electrolyte may
escape from the mirror housing if the mirror
glass breaks.
Electrolyte has an irritating effect. Do not
allow the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.
!Electrolyte drops coming into contact with
the vehicle paint finish can be completely
removed only while in the liquid state and by
applying plenty of water.
Warning!G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your
interior rear view mirror or glance over your
shoulder before changing lanes.

4Resuming to last set speedActivating cruise control
You can activate the cruise control when
the vehicle speed is above
20 mph (30 km/h).
In the following cases you cannot activate
the cruise control:
when you brake
when you have set the parking brake
when the automatic transmission is set
to positionP, R, or N
if the ESP® is switched off
if the ESP® has switched off due to a
malfunction
Warning!G
The cruise control brakes automatically so
that the set speed is not exceeded. The
brake pedal depresses automatically when
the cruise control engages the brakes.
Keep driver’s foot area clear at all times,
including the area under the brake pedal.
Objects stored in this area may impair pedal
movement which could interfere with the
braking ability of the cruise control system.
Do not place your foot under the brake pedal
– your foot could become caught.
Keep in mind that the cruise control is a
convenience system designed to assist the
driver during vehicle operation. The driver is
and must always remain responsible for
the vehicle’s speed and for safe brake
operation.
iThe vehicle speed displayed in the speedo-
meter can briefly vary from the speed setting for
the cruise control system.

crements of 1 mph (Canada: 1 km/h).Adjustment in 5 mph
(Canada: 10 km/h) increments
!Setting the automatic transmission toN
while driving cancels the cruise control.
However, the automatic transmission should not
be set toN while driving except to coast when
the vehicle is in danger of skidding (e.g. on icy
roads).
iDepressing the accelerator pedal does not
deactivate the cruise control. After brief acceler-
ation (e.g. for passing), the cruise control will re-
sume the last speed set.
iThe set speed value is increased in 1 mph
(Canada: 1 km/h) increments each time you lift
the cruise control lever to the resistance point.
Warning!G
You can increase the vehicle speed in
5 mph (Canada 10 km/h) increments.
When using this feature, keep in mind that it
may take a brief moment until the vehicle
has reached the set speed.
Increase the vehicle set speed to a value
that the prevailing road conditions permit.
Otherwise, sudden and unexpected acceler-
ation of the vehicle could cause an accident
and/or serious injury to you and others.
iThe set speed value is increased in
5 mph (Canada: 10 km/h) increments each time
you lift the cruise control lever past the
resistance point.
