Driving
56 do not pull it too strongly. In doing so, con-
tinuously press the button of the handbrake
lever.
Strong application of the handbrake can
lead to overbraking of the rear axle and
associated 'fishtailing' of the vehicle rear
end.
The brake lamps do not light up when the
handbrake is engaged.
Vehicles with manual or SMG transmission:
When parking on inclines, engage the
handbrake, as even engaging the first or
reverse gear might not under certain cir-
cumstances secure the vehicle against
moving.
Vehicles with automatic transmission:
Engage selector-lever position P.<
To prevent corrosion and one-sided
braking action, occasionally engage
the handbrake lightly when the vehicle is
slowly coming to a standstill if the traffic
conditions are suitable.<
Manual transmission
While shifting gear in the 5th/6th gear
level, press the gearshift lever to the
right, as otherwise engine damage could
occur from inadvertently engaging a gear in
the 3rd/4th gear level.
On inclines, do not hold the vehicle with the
clutch; use the handbrake. Otherwise there
is high clutch wear.<
Reverse gear
Select only when the vehicle is completely
stationary. When pressing the gearshift
lever to the left, overcome some resis-
tance.The backup lamps automatically switch on
in ignition key position 2.
SMG Sequential manual
transmission*
The concept
The SMG Sequential manual transmission
is an automated manual transmission in
which an electro-hydraulic system handles
the clutching and gear changes.
You operate the SMG using the selector
lever in the center console and two shift
paddles on the steering wheel.
It offers the following functions:
>Choice of manual or automatic mode:
Sequential mode or Drive mode
>Options of two drive programs:
Normal or Sport, refer to page 59
>Protection against incorrect gearshifts
and automatic shift down at minimum
engine speed, also in the Sequential
mode
>Kickdown function in the Drive mode
>Acceleration assistant, refer to
page 60.
The SMG is operational in ignition key posi-
tion 2.
Selector-lever positions
The current selector-lever position is dis-
played on the center console.
>R: Reverse gear
>N: Neutral, idle

PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Signal tones and a visual display
* indicate
the current distance to an object behind or
in front of your vehicle. To measure the dis-
tance, there are four ultrasonic sensors in
each bumper. The sensors at the front and
at the two rear corners have a range of
approx. 20 in/50 cm; the rear middle sen-
sors have approx. 5 ft/1.50 m.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed,
as otherwise the physical circumstances
would mean that the system warning was
too late.<
Automatic mode
In ignition key position 2, the system auto-
matically assumes operational status after
a few seconds each time you engage
reverse gear or selector-lever position R.
Wait this short period before driving.<
The system is automatically deacti-
vated once the vehicle travels approx.
165 ft/50 m or exceeds a speed of roughly
20 mph/30 km/h; the indicator lamp goes
out. You can reactivate the system manu-
ally as needed.
Manual mode
With the ignition key in position 2, press the
button; the indicator lamp lights up.
Deactivating manual mode
Press the button again; the indicator lamp
goes out.
Signal tones
The signal indicating the distance to the
nearest obstacle is directional. Thus, an
object detected to the left rear of the vehi-
cle will be indicated by a signal tone from
the left rear speaker, etc. As the distance
between vehicle and object decreases, the
intervals between the tones become
shorter. The signal tone becomes continu-
ous once the distance to the nearest object
falls to below roughly 1 ft/30 cm.
The warning signal is canceled after
approx. 3 seconds if you are moving paral-
lel to a wall.
Malfunctions
The indicator lamp within the button
flashes and a message appears on the
Control Display. PDC has failed. Switch off
PDC. Have the system checked.
As a preventive measure, keep the sensors
clean and free of ice or snow in order to
ensure that they will continue to operate
effectively.
PDC with visual warning*
You also enjoy the option of having the sys-
tem show distances to objects on the Con-
trol Display. The Control Display will also

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 4500 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.
SMG Sequential manual
transmission
Do not use the acceleration assistant dur-
ing the break-in period, refer to page 60.
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.
After component replacement
You should also comply with these break-in
procedures should the components men-
tioned above need to be replaced at a later
point.
General driving notes
Hot exhaust system
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 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 a car wash
Fold in the exterior mirrors manually, as
otherwise they could be damaged 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
