Intelligent maintenance computer
for the Cayenne (V6)
The maintenance intervals (service indicator)
shown on the multi-purpose display depend on the
mileage, the time since the last service and the
operating conditions of the vehicle.
If the vehicle is operated under heavy load, the
interval between two services is shorter than
under normal operating conditions.
f For information on messages on the multi-
purpose display:
Please observe the chapter "OVERVIEW OF
WARNING MESSAGES" on Page 135.
Emission control
Warning light
The emission control system detects malfunctions
early that could, for example, cause increased
pollutant emissions or consequential damage.
Faults are indicated by the warning light on the
instrument panel which then either lights up contin-
uously or flashes.
The faults are recorded in the control unit's fault
memory.
The warning light on the instrument panel lights up
when the ignition is switched on as a lamp check
and goes out approx. 4 seconds after the engine
starts.
The warning light on the instrument panel flashes
to indicate operating states (e.g. engine misfiring)
which might cause damage to certain parts of the
emission control system.
f In this case, immediately reduce the engine
load by easing off the accelerator.
The warning light in the instrument panel is lit
continuously after the critical range is left.
In order to avoid consequential damage to
the engine or the emission control system
(e.g. catalytic converter):
f Consult a qualified specialist workshop. We
recommend that you use a Porsche partner for
this work since these are staffed with trained
personnel and have the necessary parts and
tools.
d
Caution!
Risk of damage. If the warning light in the
instrument panel continues flashing even
when you have eased off the accelerator
pedal, the emission control system may
overheat.
f Stop as soon as possible in a safe place.
Make sure that combustible materials, such as
dry grass or leaves, cannot come into contact
with the hot exhaust system.
f Switch off the engine.
f Have the fault remedied.
