Interrupting cruise control operation – OFF
The speed driven before the interruption remains stored in the memory and can be reactivated by pressing the control stalk.

  • Please see the chapter "RESUMING THE STORED SPEED – RESUME" on page 168.
  • Press the control stalk down (position 3). or
    Press the brake or clutch pedal or move the Tiptronic S selector lever to position N.

Cruise control operation is interrupted automatically:

  1. If the set vehicle speed is exceeded by more than approx. 16 mph (25 km/h) for longer than 20 seconds.
  2. If the actual vehicle speed falls below the set vehicle speed by approx. 37 mph (60 km/h) for longer than 60 seconds (e.g. gradients).
  3. If Porsche Stability Management (PSM) intervenes for longer than 0.5 seconds.

Resuming the stored speed – RESUME

  • Press the control stalk up (position 4).
    Cruise control accelerates/decelerates the vehicle to the stored speed.

The stored speed should only be recalled if traffic and road conditions are conducive to driving at that speed.

Switching cruise control readiness off

  • Press button A on the control stalk.
    The memory is cleared and the readiness symbol disappears.

The stored desired speed is cleared when the ignition is switched off when the vehicle is parked.

On upward or downward slopes, the set speed cannot always be maintained by cruise control.

  • To obtain sufficient engine braking or a better engine-speed range, you therefore have to change down to a lower gear.

Adaptive Cruise Control (ACC)
Adaptive cruise control maintains any selected speed between approx. 20–100 mph (30–160 km/h) when driving on open roads without you having to use the accelerator.

If a vehicle traveling ahead of you in the same lane is detected as driving slower than the selected speed, adaptive cruise control will automatically maintain a set distance from the vehicle in front.

Adaptive cruise control slows your vehicle down if the distance to the vehicle ahead becomes too short and accelerates your vehicle if the distance increases.

Misuse of Adaptive Cruise Control
If the current traffic situation does not allow you to drive safely at a constant speed and with sufficient distance to the vehicle in front, using the adaptive cruise control can cause accidents.

  • Do not use the adaptive cruise control in heavy traffic, in construction traffic, in city traffic, on twisting roads or under unfavorable road conditions (e.g. wintry or wet conditions, varying road surfaces).
  • Brake the vehicle immediately with the footbrake if the deceleration of the adaptive cruise control is not sufficient.
  • Make sure that it is possible to take over control of the vehicle at all times.
  • Observe all local and national speed limits.
