Driving<br />

Resuming a speed stored beforehand<br />

Press the button, arrow 4. The last stored<br />

speed is resumed and maintained.<br />

In the following instances, the stored speed is<br />

deleted and can no longer be resumed:<br />

> When driving stability control systems are<br />

intervening<br />

> In cars with manual transmission: when you<br />

shift gears very slowly or shift to neutral<br />

> In cars with automatic transmission: when<br />

you engage selector lever position N<br />

> In cars with Sports automatic transmission<br />

with double clutch: when you engage selector<br />

lever position N<br />

> When the ignition is switched off<br />

If --- mph or --- km/h temporarily appears<br />

in the instrument cluster display, it is possible<br />

that the system prerequisites for operation<br />

are currently not met.<br />

the system has failed. More information<br />

Active cruise control*<br />

The concept<br />

With active cruise control, you can select a<br />

desired speed which is not only automatically<br />

maintained when driving on open roadways, but<br />

also varied to maintain a selected distance setting<br />

as slower traffic is encountered.<br />

Active cruise control is a technological advance<br />

over the familiar cruise control and is a welcome<br />

relief from the constant adjustment of speed<br />

that can accompany driving in traffic on highways<br />

or other high-speed thoroughfares. Especially<br />

on longer trips, the system can reduce<br />

fatigue and tension, while increasing your<br />

enjoyment of driving. Please use it safely and<br />

responsibly.<br />

Within the limits of its capability, the system<br />

automatically adapts the car's speed to that of a<br />

slower vehicle in front of you. You can specify<br />

the distance to be maintained from the vehicle<br />

in front in four stages. For safety reasons, the<br />

distance is speed-dependent. Based on your<br />

selected distance setting, the system automatically<br />

decreases the throttle setting and lightly<br />

applies the brakes if necessary. The vehicle<br />

brake lamps will automatically illuminate to<br />

signal a following driver to take action. In addition,<br />

it may be necessary for the vehicle or the<br />

driver to downshift, depending on the kind of<br />

transmission your vehicle is equipped with, to<br />

maintain the distance setting selected. If the<br />

vehicle ahead speeds up or when the lane<br />

ahead becomes clear, your vehicle will accelerate<br />

to the speed you have selected by increasing<br />

the throttle setting and shifting gears automatically<br />

or by the driver as needed. Your<br />

selected speed will be held when driving downhill,<br />

too.<br />

Since this active cruise control system is a new<br />

technology and operates differently from conventional<br />

cruise control systems which you may<br />

be accustomed to, you are strongly urged to<br />

read all of the pages relating to this system<br />

before use. Pay special attention to the System<br />

limitations section beginning on page 69.<br />
