Shifting gears via the selector lever
Move selector lever from position D toward the 
left into the M/S shifting slot:
When you press the selector lever forwards or 
backwards, the manual mode is activated and 
Steptronic changes gear.
The engaged gear, e.g. M1 is displayed in the 
instrument cluster.
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 executed by the system.
The gear selected is briefly displayed in the 
instrument cluster, followed again by the gear 
actually in use.
Shifting gears via shift paddles* on the 
steering wheel
The shift paddles allow you to shift gears 
quickly since both hands can remain on the 
steering wheel.
>When you use the shift paddles on the 
steering wheel to shift gears in automatic 
mode, the transmission switches to manual 
mode.>If you do not accelerate or shift gears using 
the shift paddles for a certain amount of 
time, the transmission switches back to 
automatic mode.
If the selector lever is in the M/S gear 
plane, manual mode remains active.<
>To upshift, briefly pull the right shift 
paddle +.
>To downshift, briefly pull the left shift pad-
dle –.
Upshifts and downshifts are executed only 
when they will result in a plausible combination 
of engine and vehicle speed; thus, for example,

Since this active cruise control system is a new 
technology and operates differently from con-
ventional cruise control systems which you may 
be accustomed to, you are strongly urged to 
read all of the pages relating to this system 
before use. Pay special attention to the System 
limitations section beginning on page73.
Braking sensation
>If you step on the brake pedal while the sys-
tem is braking, pedal sensation will be 
slightly different from the usual.
>Possible noises during automatic braking 
are normal.
Manual transmission
You can shift gears while cruise control is acti-
vated. The system is deactivated when you 
drive at very low engine speeds for an extended 
period.
Range of applications
The minimum desired speed is 20 mph or 
30 km/h, the maximum desired speed is 
110 mph or 180 km/h.
As with conventional cruise control sys-
tems, active cruise control in no way 
diminishes or substitutes for the driver’s own 
personal responsibility, alertness and aware-
ness in adjusting speed, braking or otherwise 
controlling the vehicle. The driver should 
decide when to use the system on the basis of 
road, traffic, visibility, and weather conditions. 
Active cruise control is intended for use on 
highway-type roadways where traffic is moving 
relatively smoothly. Do not use this system in 
city driving; heavy traffic such as during rush 
hour; on curvy, winding roads, slippery roads or 
roads with sharp curves such as highway off-
ramps; during inclement weather such as snow, 
strong rain or fog; or when entering inter-
changes, service/parking areas or toll booths. 
It is also important to regulate your vehicle's 
speed and distance setting within applicable 
legal limits. Always be ready to take action or 
apply the brakes if necessary, especially when 
the system is actively following a vehicle in front of you. Otherwise, driving situations could 
result that pose the risk of accidents.<

System limitations
Always remember that the range and abil-
ity of the system does have physical limi-
tations. It will not apply the brakes or decelerate 
your vehicle when there is a slow-moving vehi-
cle, stopped vehicle or stationary object ahead 
of you, as for example, at a traffic light or a 
parked vehicle. Also, the system does not react 
to oncoming traffic, pedestrians or other types 
of potential traffic such as a rider on horseback. 
It is also possible that the system may not 
detect smaller moving objects such as motor-
cycles or bicycles. Be especially alert when 
encountering any of these situations as the sys-
tem will neither automatically brake, nor provide 
a warning to you. Also, be aware that every 
decrease in the distance setting allows your 
vehicle to come closer to a vehicle in front of 
you and requires a heightened amount of alert-
ness.<
Active cruise control is not and must not 
be used as a collision avoidance/warning 
system.<
If while your vehicle is actively following a vehi-
cle in front of you and the vehicle ahead speeds 
up or the lane ahead becomes clear, then your 
vehicle will accelerate to the speed you have 
selected. Be aware that changing to a clear, 
unobstructed lane will also result in your vehicle 
accelerating.
Be certain to deactivate the system when 
you pull into an exit lane for a highway off-
ramp.<
Also, vehicles traveling in a staggered manner 
on a highway may cause a delay in the system's 
reaction to a vehicle in front of you or may cause 
the system to react to a vehicle actually in the lane next to you. Always be ready to take action 
or apply the brakes if necessary.
While active cruise control is capable of 
braking your vehicle automatically when 
you approach a slower vehicle ahead, it is 
important to be aware that the ability of the sys-
tem to apply the brakes is also limited, e.g. 
when you reduce your desired speed sharply. 
The system cannot stop your vehicle. It uses 
only a portion of braking system capacity and 
does not utilize the full capacity of the vehicle 
braking system. Therefore, the system cannot 
decrease your speed for large differences in 
speed between your vehicle and the vehicle 
ahead. Examples: when you approach a vehicle 
traveling at a much lower speed than your own 
speed such as approaching a toll booth or when 
a much slower vehicle cuts in front of you at 
close range.<
Active cruise control can only decelerate the 
vehicle to approx. 20 mph or 30 km/h.
