Opening and closing
Convertible top operation with Comfort Access,
also refer to page 34.
As of radio readiness, refer to page 61:
To conserve battery power, if possible
operate the convertible top only while the
engine is running.
Prior to closing the conv ertible top, check for
and remove all debris from the windshield
frame; otherwise, the closing of the top may be
hampered. <
1 Push button: close the convertible top
2 Push button: open convertible top
3 LEDs
The side windows move down when the
convertible top is opened. <
If it is no longer possible to operate the cover
after it has been actuated several times in
immediate succession or after the cover has
remained in an interm ediate position for a
longer period, then the convertible top drive has
overheated. If possible, close the convertible top and allow
the drive unit to cool for a few minutes.
Operating while driving
You can open or close the convertible top while
driving, as long as the car is not moving faster
than approx. 25 mph/40 km/h.
If you accelerate to ov
er 30 mph/50 km/h while
the convertible top is moving, the procedure is
interrupted.
While operating the convertible top, pay
close attention to the surrounding traffic;
otherwise, an accident may happen. Try to
avoid operating the convertible top while
reversing the vehicle since the rear view is very
limited during the convertible top's movement.
Do not operate the convertible top while driving
in windy conditions. Do not drive faster than
30 mph/50 km/h; otherwise, damage to the
vehicle can occur. <
LEDs
>While the convertible top is being operated,
the left LED lights up green. It goes out as
soon as the top is fully opened or closed.
In the following situations, a message appears
on the Control Display or an acoustic signal
sounds in addition to the LED lighting up:
> If the right-hand LED flashes red when you
release the button, th e opening or closing
action has not yet finished.
> If the right-hand LED lights up red when the
button is pressed, the trunk partition is
raised, the trunk lid is not closed or there is a
malfunction. The convertible top cannot be
moved.
Interruption
The automatic sequence of movements is
interrupted if the button for the convertible top
operation is released. The sequence can be
continued in the desired direction by pushing or
pulling the buttons.

ControlsDriving
Ignition on
All electrical consumers can operate. The
odometer and trip odometer are displayed in
the instrument cluster.
When the engine is off, please switch
off the ignition and any unnecessary
electrical consumers in order to preserve the
battery. <
Radio readiness and ignition off
All indicator and warnin g lamps as well as
displays in the instrument cluster go out.
Starting the engine
Do not run the engine in enclosed areas;
otherwise, the inhalati on of toxic exhaust
gases can cause loss of consciousness and
death. The exhaust gases contain carbon mon-
oxide, an odorless and colorless, but highly
toxic gas. Never leave an unattended vehicle
with the engine running; otherwise, such a
vehicle represents a po tential safety hazard.
Before leaving the car with the engine running,
place the transmission in neutral or move the
selector lever to positi on P and forcefully apply
the parking brake to prevent the car from
moving. <
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds. Avoid frequent starting in quick succes-
sion as well as repeated start attempts in
which the engine does no t start. Otherwise, the
fuel is not burned or incompletely burned and
there is a danger of overheating and damaging
the catalytic converter. <

>To upshift, briefly pull the right shift
paddle +.
> To downshift, briefly pull the left shift
paddle –.
Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; thus, for example,
a downshift that would cause the engine to
overrev will not be exec uted by the system.
The gear selected is briefly displayed in the
instrument cluster, followed again by the gear
actually in use.
Overriding selector lever lock
If the selector lever will not move out of
position P even though the ignition is switched
on, the brake is depressed, and the button on
the selector lever is pre ssed, the selector lever
lock can be overridden:
1. Unclip the sleeve of the selector lever.
2. Pull the sleeve up over the selector lever
until the sleeve is inside out.
3. Using the screwdriver from the onboard
vehicle tool kit, refer to page 243, press the
red lever, see arrow, while moving the
selector lever to the desired position.
7-gear Sport automatic
transmission with double
clutch
The concept
The 7-gear Sport automatic transmission with
double clutch is an automated manual trans-
mission with two clutches and secondary gear
sets in which the clutching and shifting is
handled by an electr ohydraulic system.
With the 7-gear Sport automatic transmission
with double clutch, the gears are shifted without
an interruption in driving power.
You operate the 7-gear Sport automatic trans-
mission with double clutch using the selector
lever and two shift paddles on the steering
wheel.
It offers you the following functions:
> Either manual or au tomatic mode: sequen-
tial mode or drive mode
> Automatic downshifting and protection
against incorrect gear selection, even in
sequential mode
> Acceleration assistan t, Launch Control,
refer to page 70
> Automatic intermediate throttle application
System limitations
The 7-gear Sport automatic transmission with
double clutch has an overheating protection
that protects the clutch from extreme loads.
The indicator lamp lights up in yellow if
the transmission becomes too warm.
Avoid high engine loads and frequent
accelerations from zero. If the transmission is
overheated, the indicator lamp lights up in red
and the power flow to the motor is interrupted. It
is only possible to continue driving once the
transmission has cooled down.
Avoid frequent powerful accelerations from
zero and do not hold the vehicle on inclines by
pressing lightly on the accelerator while letting
the clutch slip, as this may cause the transmis-
sion to overheat.

Things to remember when driving
Driving tips
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least br aking is required. Even
light but consistent brak e pressure can lead to
high temperatures, brake wear and possibly
even brake failure. <
You can increase the engine's braking effect
by shifting down, all the way to first gear if nec-
essary. This strategy helps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mo de of the automatic
transmission, refer to page 65.
Sport automatic transm ission with double
clutch: never drive with the transmission
in neutral or with the en gine switched off; other-
wise, there will be no en gine braking action and
no power assistance to the brakes and steering.
Manual transmission: never drive with the
clutch held down, with the transmission in neu-
tral or with the engine switched off; otherwise,
there will be no engine braking action and no
power assistance to the brakes and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals; otherwise, pedal function could be
impaired. <
Corrosion on brake rotors
When the vehicle is driv en only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are le ss frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminan ts accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
When the vehicle is parked
Condensation forms while the automatic
climate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Cargo loading
To avoid loading the tires beyond their
approved carrying ca pacity, never over-
load the vehicle. Overlo ading can lead to over-
heating and increases the rate at which damage
develops inside the tires. In some situations,
this can result in sudden loss of tire pressure. <
Avoid fluid spills in the trunk as they could
damage the vehicle. <
Determining loading limit
1.Locate the following statement on your
vehicle's placard:
The combined weight of occupants
and cargo should never exceed
XXX kg or YYY lbs. Otherwise damage to
the vehicle may occur and unstable driving
conditions may result.<
2. Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver
and passengers from XXX kilograms or YYY
pounds.
4. The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals
