Selector-lever positions
The current selector-lever position is dis-
played on the center console.
R: Reverse gear
N: Neutral, idle
Position for forward driving with one-touch
functions:
Sequential mode
+: manual upshifts
Ñ: manual downshifts
D: Drive mode.
The SMG is operational in ignition key posi-
tion 2.
Idle is automatically engaged if the
driver's door is opened with the
engine running and neither pedals, shift
paddles nor the selector lever are oper-
ated.
This is signaled by an acoustic signal and
the flashing gear indicator. The gear dis-
play N appears in the instrument cluster.
A driving position can only be selected with
the driver's door closed.
When the vehicle is unlocked, a buzzing
sound in the area of the transmission sig-
nals that the system is ready for opera-
tion.<
Shiftlock
For your safety a driving position can only
be engaged from the selector lever
position N with the vehicle stationary with
the brake pedal depressed.
Observe the following when driving
Start off quickly on slopes. Do not
hold the vehicle on a hill by pressing
the accelerator, but apply the handbrake
instead. Otherwise overheating can occur
in the area of the transmission.<
R Reverse
Select R only when the vehicle is com-
pletely stopped.
N Neutral: idle
Engage prior to every engine start, refer
also to page 50.
Sequential mode
After every engine start, as soon as the
selector lever is brought into a forward gear
position and the brake is pressed, the
sequential mode is activated.
The gear is changed using the shift paddles
or selector lever.
Driving off is also possible in second gear,
e.g. when there is snow on the roadway.
D Drive mode
In the Drive mode, all forward gears are
shifted automatically.
To switch from the sequential to Drive
mode: briefly press the selector lever to the
right towards D.
For rapid acceleration, e.g. overtaking,
press the accelerator pedal as far down as
it will go Ð kickdown.
Kickdown:
The kickdown mode provides maximum
acceleration.
Press the accelerator pedal beyond the
full-throttle resistance point.
To return to the sequential mode: briefly
press the selector lever back to the right

Break-in procedures
To ensure that your vehicle continues to
provide optimized economy of operation
throughout an extended service life, we
request that you devote careful attention to
the following section.
Engine and differential
Up to 1,200 miles/2,000 km:
You should attempt to vary both vehicle
and engine speeds. Until the break-in
period has been completed, you should
also refrain from exceeding an engine
speed of 4,500 rpm or a driving speed of
100 mph/160 km/h.
Always obey all official speed limits.
Avoid full-throttle operation and use of the
transmission's kickdown mode during
these initial miles.
Once you have driven 1,200 miles/
2,000 km, the engine and vehicle speeds
can be gradually increased.
You should also comply with these break-in
procedures should the engine or differen-
tial need to be replaced at a later point.
Sequential manual transmission
SMG
Do not use the acceleration assistant dur-
ing the break-in period.
Tires
Due to technical factors associated with
their manufacture, tires do not achieve their
full traction potential until after an initial
break-in period. Therefore, drive reservedly
during the first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve opti-
mized contact and wear patterns between
brake pads and rotors.
Clutch
The function of the clutch is only at its opti-
mized level after a distance driven of
approx. 300 miles/500 km. During this
break-in period, engage the clutch gently.
General driving notes
High temperatures
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Do not remove
the heat shields installed adjacent to vari-
ous sections of the exhaust system, and
never apply undercoating to them. When
driving, standing at idle and while parking
take care to avoid possible contact
between the hot exhaust system and any
highly flammable materials such as hay,
leaves, grass, etc. Such contact could lead
to a fire, and with it the risk of serious prop-
erty damage as well as personal injury.<
Parking the vehicle
Condensation forms in the air conditioner
system during operation, and then exits
under the vehicle. Traces of condensed
water under the vehicle are thus normal.
Before driving into the car wash
Fold in the exterior mirrors, refer to
page 42, as otherwise they could be dam-
aged due to the width of the vehicle.
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a
wedge of water can form between tires and
road surface.This phenomenon is referred
to as hydroplaning, and is characterized by
a partial or complete loss of contact
between the tires and the road surface, ulti-
mately undermining your ability to steer
and brake the vehicle.<
