S tronic transmission
Applies to vehicles: w ith S tronic®
Introduction
Your vehicle is equipped with a S tronic transmission, also called a
double -clutch system/transmission.
Power is transferred between the engine and the transmission by means of two independent clutches. They replace the torque
converter of conventional automatic transmissions and al low the
vehic le to accelerate without a noticeable break in the power flow .
With the aid of
ti pt ronic, the gears can optionally be shifted manu­
ally => page 118 . •

t ions
The se lector lever position is shown in the instrument cluster
display by highlighting the appropriate symbol.
P -Park lock
In this position the gears are mechanically locked .
The park lock must only be engaged w ith the vehic le
stationary
=> & .
To engage P and to remove the lever from this position, you must
depress the release button (button in the selector lever handle)
and
simultaneously you must step on the brake pedal.
R -reverse
In this position, reverse is engaged.
Reverse gear must only be engaged with the vehic le
stationary and
the engine running at id le speed =>& .
To engage R, you have to depress the release button
and simulta­
neously step on the brake pedal. In the R position, the back -up lights
i ll uminate with the ignition on.
N -N eutra l
The transmission is in neutra l in this pos ition.
D -Norm al po siti on fo r dri vin g fo rw ard
In this position, the forward gears are automatical ly shifted up and
down, depending on engine load and vehicle speed.
To engage S from
N, the brake peda l must be depressed at speeds
below 5 km/h or when the vehicle is stationary=>& .
In certain circumstances (driving in the mountains for examp le) it
can be beneficial to switch temporarily to the manual shift program
=>
page 118 in order to adjust the gear ratios to driving conditions
manually .
S -S po rt setting
The S setting should be selected for sporting driving. The power
reserves of the engine can be fully exploited through later upshifts .
To engage S from N, the brake peda l must be depressed at speeds
below 5 km/h or when the vehicle is stationary=>& . .,_

• ..__T_ ra_ n_s_ m_ i_ s _s_ i_ o _n ___________________________________________________ _
The selector lever lock is effective only when the vehicle is
stationary and at speeds below 5 km/h. At higher speeds, the lock in
the N position is automatically switched off.
The selector lever is not locked when rapid shifts are made through
t he N position (e.g . from R to Dl. This allows you to "rock" the vehicle
if it becomes stuck . If the lever is in the N position for more than
1 second with the brake pedal not depressed, the selector lock
engages automatically.
Release b utt o n
The release button in the selector lever handle prevents accidental
shifts in to certain selector lever positions. When you press the
re lease button, the selector lever lock is cancelled. In the illustra ­
t ion, the positions in which the release button has to be pressed are
highlighted in color=>
page 115, fig. 115.
Igniti on k ey remo val lock
The ignition key can only be remove after the ignition is switched off
if the selector lever is in P . As long as the ignition key is removed, the
selector lever is locked in P.
[ i J Tip s
If the selector lever does not engage, there is a malfunction . The
engine is disabled to prevent the vehicle from driving off uninten­
tiona lly. To a llow the selector lever to engage again, proceed as
follows: Press and release the brake pedal. •

What impa
irs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted.
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety
risks for everybody in the vehicle increase and you also
become a hazard to everyone else on the road =>& .There ­
fore:
Do not let yourself be distracted by passengers or by
using a cellular telephone .
NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc.).
- Observe all traffic laws, rules of the road and speed limits
and plain common sense .
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more
than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed .
& WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used. •
