Check Engine
(Emission Control)The emission control system detects malfunctions
early that could, for example, cause increased
pollutant emissions or consequential damage.
Faults are indicated by a continuously lit or
flashing instrument panel warning light.
The faults are recorded in the control unit's fault
memory.
The warning light in the instrument panel lights up
when the ignition is switched on as a bulb check
and goes out approx. 4 seconds after the engine
starts. If the warning light does not light up, have
the bulb replaced promptly.
The warning light in the instrument panel flashes to
indicate operating states (e.g. engine misfiring)
which might cause damage to certain parts of the
emission control system.
fIn this case, immediately reduce the engine
load by easing off the accelerator.
f In order to avoid consequential damage to the
engine or emission control system (e.g. cata-
lytic converter), have the fault diagnosed and
rectified immediately at the nearest authorized
Porsche dealer. If the warning light in the
instrument panel lights up
permanently without flashing before and remains
on while driving, it suggests:
– a potential engine control problem and the need for system service or
– an improperly fastened tank cap or
– the vehicle was refueled while the engine was running.
f Stop immediately at a suitable and secure
place and check tank cap for proper fastening.
If tank cap was fastened correctly, see your au-
thorized Porsche dealer for service as soon as
possible.
Caution!
If the check engine warning light in the in-
strument panel is flashing, serious catalytic
converter damage and power loss will soon
occur.
Prolonged driving with the check engine war-
ning light on could cause damage to the
emission control system. It also could affect
fuel economy and driveability.
f Have the fault remedied at the nearest authorized Porsche dealer immediately.

CHRONO
StopwatchYou can use the stopwatch to measure time inter-
vals, e.g. on the race circuit or on work-related
journeys. Measured lap times can be stored and
evaluated if the vehicle is equipped with Porsche
Communication Management (PCM).
fPlease observe the chapte r “Sport display” in
the separate PCM operating instructions. Stopwatch on the instrument panel
The stopwatch has an analogue and a digital dis-
play.
The large pointer of the analogue display meas-
ures the seconds. The two small pointers measure
hours and minutes. The display re-starts at zero af-
ter 12 hours.
Seconds and increments of
1/100th of a second
can be read on the digital display.
The digital display and the display in the on-board
computer can indicate up to 99 hours and
59 minutes.
The stopwatch can be swiv elled both to the left
and to the right.
Stopwatch displays:
– on the stopwatch on the instrument panel,
– in the on-board computer menu CHRONO,
– on the performance display in the PCM.
Starting/stopping stopwatch
All stopwatch displays are started and stopped via
the on-board computer menu CHRONO. Note on operation
When you leave the CHRONO menu while the stop-
watch is running, meas
urement will continue.
The stopwatch stops after the ignition is switched
off. If the ignition is sw itched on again within ap-
prox. 4 minutes, the stopwatch will continue to
run.
The only way to reset the stopwatch to zero is by
selecting “Reset” in the CHRONO menu.

Shifting Gears
179
Depending on driving speed and engine speed,
you can shift up or down at any time.
Gear changes which would exceed the upper or
lower engine speed limit are not executed by the
controller.
There is no automatic upshift at the upper engine
speed limit in selector lever position M. Upshift
suppression can be cancelled by kickdown opera-
tion. If, for example, the engine speed limit is
reached during overtaking and the automatic
upshift does not occur, the transmission in this
case shifts up as a result of kickdown operation.
f Select an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking.
In order to shift up au tomatically at the upper
engine speed limit:
f Depress the accelerator pedal beyond the full-
throttle point (kickdown). Failure of the selector lever display on the
instrument cluster
The warning “Transmission emergency run” is
displayed in red on the on-board computer.
–Effect:
No selector lever position is displayed on the
instrument cluster.
Vehicle can be driven only until it comes to a
stop.
Remedy:
It is not possible to continue driving. Immedi-
ately stop the vehicle in a suitable place. Have
the vehicle towed to an authorized Porsche
dealer.
Please see the chapter “TOWING” on
Page 269.
Stoppingf For a brief stop (e.g. at a traffic light), leave the
selector lever in drive position and hold the
vehicle with the brake pedal.
f Do not hold the car on a slope using the
accelerator. Use the brake pedal or the
handbrake instead.
f Before leaving the vehicle, always apply the
handbrake and move the selector lever to
position P.Parkingf Go easy on the accelerator!
f When parking or manoeuvring in a small
space, control the speed by careful use of the
footbrake.Driving in winterIn wintry road conditions it is advisable to take
steep inclines in manual mo de. This prevents gear
changes occurring that could cause wheelspin.Tow-starting, towingf Please see the chapter “TOWING” on
