ation. All gears for forward travel are activated
automatically.
R Reverse Select only when the vehicle is stationary.
N Neutral
The vehicle may roll. Use in automatic car
washes, for example.
P Park
Select only when the vehicle is stationary. The
drive wheels are blocked.
Before exiting the vehicle, make sure that se‐
lector lever position P is set. Otherwise, the ve‐
hicle may begin to move.

sition.
Engaging selector lever positions
General information To prevent the vehicle from creeping after you
select a gear, maintain pressure on the brake
pedal until you are ready to start.
The selector lever can only be taken out of se‐
lector lever position P if the ignition is on or the
engine is running.
With the vehicle stationary, depress the brake
pedal before shifting out of selector lever posi‐
tion P or N; otherwise, the shift block will not be
deactivated and the shift command will not be
executed.
Releasing the selector lever lock A lock prevents the inadvertent switching to se‐
lector lever position R or the inadvertent
change from selector lever position P.
Releasing the lock: press unlock button on the
front of the selector lever, see arrow.

ward.
Manual mode M/S becomes active and the gear
is changed.
The engaged gear is displayed in the instru‐
ment cluster, for example, M1.
If the situation requires, the Steptronic trans‐
mission continues to shift automatically.
Example: once maximum engine speed is at‐
tained, M/S manual mode is automatically up‐
shifted as needed.
Switching to manual mode
▷To shift down: press the selector lever for‐
ward.▷To shift up: pull the selector lever rear‐
wards.
Gears will only be shifted at appropriate engine
and road speeds, for example downshifting is
not possible if the engine speed is too high.
The selected gear is briefly displayed in the in‐
strument cluster, followed by the currently se‐
lected gear.
Manual mode M/S: prevent automatic
upshifting
Once a particular engine speed is attained, M/S manual mode is automatically upshifted as
needed.
For vehicles with Steptronic Sport transmission,
automatic shift operations are not performed if
one of the following conditions is met:
▷DSC is deactivated.▷TRACTION is activated.
In addition, there is no downshifting for kick‐
down.
With the respective transmission version, the
lowest possible gear can be selected by simul‐
taneously operating the kickdown and the left
shift paddles. This is not possible, when switch‐
ing briefly via the shift paddles from selector
lever position D to manual mode M/S.
Ending the sport program/manual mode
Push the selector lever to the right.
D is displayed in the instrument cluster.
Shift paddles for Steptronic Sport
transmission
The shift paddles on the steering wheel allow
you to shift gears quickly while keeping both
hands on the steering wheel.
▷Shift up: briefly pull right shift paddle.▷Shift down: briefly pull left shift paddle.▷The lowest possible gear can be selected by
pulling and holding the left shift paddles.
Gears will only be shifted at appropriate engine
and road speeds, for example downshifting is
not possible if the engine speed is too high.
The selected gear is briefly displayed in the in‐
strument cluster, followed by the current gear.
If the shift paddles on the steering wheel are
used to shift gears in automatic mode, the
transmission switches to manual mode tempo‐
rarily in selector lever position D and perma‐
nently in selector lever position S.
In selector lever position D, after conservative
driving for a certain amount of time in manual
mode or if there has been no acceleration or
shifting of the shift paddles within a certain
amount of time, the transmission switches back
to automatic mode.

WARNING
Improperly executed work can lead to
failure, malfunction or unintentional triggering
of the system. In the case of a malfunction, the
system could not trigger as intended in the
event of an accident despite respective acci‐
dent severity. There is a risk of injury or danger
to life. Have the system checked, repaired, dis‐
mantled and scrapped by a dealer’s service
center or another qualified service center or re‐
pair shop. ◀
Triggered rollover protection system WARNING
After triggering or damage, system func‐
tionality is limited or not available anymore.
There is a risk of injury or danger to life.
Have the system checked and replaced by a
dealer’s service center or another qualified
service center or repair shop in the event of
triggering of or damage to the system. ◀
WARNING
With an extended rollover protection sys‐
tem, the area of movement of the convertible
top is limited. There is a risk of injuries or a risk
of property damage. When the rollover protec‐
tion system is extended, do not move the con‐
vertible top. ◀
Malfunction A Check Control message is displayed
when there is a malfunction.
Tire Pressure Monitor
TPM
The concept
The system monitors tire inflation pressure in
the four mounted tires. The system warns you if
there is a significant loss of pressure in one ormore tires. For this purpose, sensors in the tire
valves measure the tire inflation pressure.
Information With use of the system observe further infor‐
mation found under Tire inflation pressure, re‐
fer to page 186.
Functional requirements The system must have been reset with the cor‐
rect tire inflation pressure; otherwise, reliable
signaling of tire pressure loss is not assured.
Reset the system after each adjustment of the
tire inflation pressure and after every tire or
wheel change.
Always use wheels with TPM electronics to en‐
sure that the system will operate properly.
Status display The current status of the Tire Pressure Monitor
TPM can be displayed on the Control Display,
e.g., whether or not the TPM is active.
On the Control Display:1. "Vehicle info"2."Vehicle status"3. "Tire Pressure Monitor (TPM)"

Additional information The status control display additionally shows
the current tire inflation pressures. It shows the
actual values read; they may vary depending
on driving style or weather conditions.
Carry out reset Reset the system after each adjustment of the

After driving faster than 19 mph/30 km/h for a
short period, the set tire inflation pressures are
accepted as reference values. The resetting
process is completed automatically while driv‐
ing. After successful completion of the reset,
the tires appear in green on the Control Display
and "Tire Pressure Monitor (TPM) active" is dis‐ played.
The progress of the reset is displayed.
You may interrupt this trip at any time. When
you continue the reset resumes automatically.
Low tire pressure message
The yellow warning lamp lights up. A
Check Control message is displayed.▷There is a flat tire or a major loss in
tire inflation pressure.▷A reset of the system was not carried out
after a wheel was changed. The system
therefore issues a warning based on the tire
pressures before the last reset.1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with
normal tires or run-flat tires.
Run-flat tires, refer to page 193, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire's sidewall.
WARNING
A damaged regular tire with low or miss‐
ing tire inflation pressure impacts handling,
such as steering and braking response. Run-flat
tires can maintain limited stability. There is risk
of an accident. Do not continue driving if the
vehicle is not equipped with run-flat tires. Fol‐
low the information on run-flat tires and con‐
tinued driving with these tires. ◀

Actions in the event of a flat tireNormal tires
1.Identify the damaged tire.
Check the air pressure in all four tires, e.g.
using the tire pressure gage of a tire repair
kit.
If the tire inflation pressure in all four tires is
correct, the Tire Pressure Monitor may not
have been initialized. In this case, initialize
the system.
If identification of flat tire damage is not
possible, please contact a dealer’s serviceSeite 110CONTROLSSafety110
