Controls, Instruments

If the warning lights in the instrument panel and on-

board computer go on while driving, the brake flu-

id level may be too low, or (if the brake pedal trav-

el has increased) one of the two brake circuits 

may have failed. 
A greater braking pressure will be required, stop-

ping distances will be longer and the braking be-

havior will change, particularly in curves. 
With correctly adjusted brakes, and a correctly 

working brake system, the pedal travel to the 

point of brake actuation should be approximately 

1-3/16 in to 1-9/16 in or 30 to 40 mm. 

Whenever the brake pedal travel exceeds this dis-

tance, have the brake system checked. 

Brake booster warning
The brake booster is monitored, in addition to the 

brake fluid level.
If the brake fluid warning lamp lights up after 

starting the engine, wait to drive until the required 

pressure for the brake booster is established and 

the warning light goes out.
If the brake fluid warning lamp in the instrument 

panel does not go out, there could be a defect in 

the brake booster.

f Adjust your speed accordingly for longer 

braking distances, higher required pedal 

pressures, and altered braking behavior.

f Drive carefully to an authorized Porsche deal-

er. The brake system should be repaired im-

mediatlely.

increase the stopping distance. 
f Always check the movement of the brake ped-

al before driving and make sure that it is not 

obstructed by a floor mat or any other object. 

Note
In case one of the two brake circuits fails, in-

creased pedal travel is required to bring your 

vehicle to a full stop. 

the brakes: 
f Before descending a steep grade, reduce 

speed and shift the transmission into a lower 

gear to control speed. 

f Do not “ride the brakes” by resting your foot on 

the pedal when not intending to apply brake 

pressure. 

f Do not hold the pedal down too long or too 

often. 

This could cause the brakes to get hot and not 

function properly.
