Reduced Braking Efficiency
After a long drive over salted or gritted roads, a coating may form on the brake disks and pads that significantly reduces friction and therefore also braking effect.

  • Even though the brake disks consist of alloyed gray cast iron, they will unavoidably start to corrode if your vehicle is parked for an extended period. The brakes will tend to "rub" as a result.
    The nature, extent and effects of corrosion depend on the amount of time the vehicle was parked, whether road salt or grit was spread and whether grease-dissolving agents were used in car washes (not on vehicles with Porsche Ceramic Composite Brake).
    To prevent corrosion of the brake disks, "brake them dry" before parking the vehicle (not on vehicles with Porsche Ceramic Composite Brake).
    If braking comfort is noticeably impaired, we recommend that you have the brake system checked by experts at an authorized Porsche dealer.
  • To relieve the brake system on downhill stretches, change down to a lower gear in good time (engine braking).
    If engine braking is insufficient on steep stretches, operate the footbrake at intervals. Avoid continuous braking as it overheats the brakes and reduces the braking effect.

For information on brake fluid and checking the brake fluid level:

  • Please see the chapter "BRAKE FLUID" on page 285.

New brake pads or linings
New brake pads have to be "broken in", and therefore only attain optimal friction when the car has covered several hundred miles or km.

The slightly reduced braking ability must be compensated for by pressing the brake pedal harder. This applies whenever the brake pads and/or brake disks are replaced.

A - Switch cruise control on/off
1 - Set/increase desired speed
2 - Reduce desired speed
3 - Interrupt (OFF)
4 - Return to set speed (RESUME)

Cruise Control
Cruise control maintains any selected speed between approx. 20–150 mph (30–240 km/h) without you having to use the accelerator.

Cruise control is operated using the control stalk at the bottom left of the steering wheel.
