2009 PORSCHE PANAMERA cruise control

Driving and Driving Safety
187
Traffic situations in which vehicles are
not reliably detectedThe radar sensor for adaptive cruise control
scans a narrow, cone-shaped area in front of
your vehicle.
Detection can be limited or unreliable, depending
on the traffic situation and the size of the vehicle
in front. The system may brake too late or
unexpectedly. Stationary vehicles are not
detected. The system is unable to react to them.
Tip on driving
fDrive with extreme care.
f Slow down if necessary.
A – Vehicles changing lanes/cutting in
If a vehicle is changing la nes or cutting in ahead of
you in the same lane, th e vehicle will only be
detected when it has moved completely into your
lane.
B – Vehicles with a small cross-section/
narrow vehicles
Narrow or small vehicles will not be detected or
will be detected too late.
C – Driving into and out of corners
When driving into and out of corners, vehicles will
not be detected or will be detected too early, or
adaptive cruise control will react to vehicles in
adjacent lanes.

Driving and Driving Safety

When you brake in the ABS control range,
the vehicle is stabilised even when PSM is
switched off.
One-sided spinning of the wheels is prevented,
even with PSM switched off.
PSM should always be switched on during
“normal” driving.
H o w e v e r, i t m a y b e a g o o d i d e a to s w it c h o f f P S M
temporarily in exceptional situations:
– On a loose surface and in deep snow.
– When “rocking the vehicle free”.
– When using snow chains.
Tip on driving
The vehicle retains its enhanced braking readiness
through prefilling of the br ake system even when
PSM is switched off.
When PSM is switched off, wheel-specific brake
interventions and the anti-slip control system (ASR)
are also switched off.
The automatic brake differential (ABD) remains on.
Adaptive cruise control is deactivated when PSM
is switched off.
When PSM is switched off, the slip monitoring
function of Porsche Doppelkupplung (PDK) is also
deactivated.
Switching PSM back onf Press button .
PSM is active immediately.
The indicator light on the button and the
PSM OFF warning light on the instrument
panel go out.
The message “PSM switched on” appears on
the multi-function disp lay in the instrument
panel.“Sport Plus” modeA sportier setup is obtained when “Sport Plus”
mode is switched on.
PSM interventions occur later than in Normal
mode. The vehicle can be maneuvered with
greater agility at its pe rformance limits, without
having to dispense with th e assistance of PSM in
emergency situations. This helps to achieve
optimal lap times, particular ly on race circuits and
on a dry road surface. – The PSM warning light on the instrument panel
lights up for a lamp check when the ignition is
switched on.
– The light indicates a control operation, even when PSM is switched off, e.g. brake control in
the event of one-sided wheel spin.
– The light - in conjunction with the multi-function display - indicates a fault.
The warning message “PSM failure” appears
on the multi-function display in the instrument
panel.
For information on warning messages on the multi-
function display:
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 152.
f Adapt your driving style according to the
changed conditions.
f Contact a qualified spec ialist workshop in
order to correct the fault. We recommend that
you have an authorized Porsche dealer to do
this work, as they have the trained workshop
personnel and the necessary parts and tools
for this type of work.

Driving and Driving Safety
HOLD function: Drive-Off Assistant and
standstill management The HOLD function assists the driver when
stopping and driving off on upward slopes.
The vehicle is automatically prevented from rolling
back away from the desired direction of travel.
When the HOLD function is active, the function
light on the instrument panel lights up.
When adaptive cruise control is operating
normally, the HOLD function holds the vehicle
following automatic braking until the vehicle is
actively held in a stationary position.
Notes on operation
The HOLD function is no t available if the PDK
selector lever is in position N.
If the PDK selector lever is moved while the
HOLD function is active, the HOLD function is
deactivated.
If the driver’s seat be lt is unbuckled and the
driver’s door is opened wh ile the HOLD function is
active, the electric park ing brake is activated
automatically.
For information on the electric parking brake:
f Please see the chapter “ELECTRIC PARKING
BRAKE” on page 171.
Warning!
In spite of the advantages of the HOLD function, it
is still the driver’s responsibility to adapt his
driving style and maneuvers in line with road and
weather conditions, as well as the traffic situation.
The increased safety that is provided should not
induce you to take greate r risks with your safety.
Caution!
If the vehicle comes to a stop on a steep
uphill gradient without operation of the
footbrake by the driver, this may result in a
certain roll-back before the vehicle is held by
the HOLD function. In this situation, the roll-
back can be reduced by operating the
footbrake.
f Assist holding of the vehi cle by increasing the
brake force with the footbrake.
Brake pedal feels different. When adaptive
cruise control is operating normally or when
the HOLD function is active, the brake pedal
may feel different and you may hear
hydraulic noises.
This behavior is no rmal for the system.
It is not a fault.
Danger!
Risk of accidents. The limits set by physics of
driving cannot be overcome, even with HOLD
function. The responsibi lity for stopping and
driving off on uphill gradients is still the
driver’s, despite the HOLD function.
Assistance by the HOLD function is not
always guaranteed when stopping and
driving off on a slippery surface (e.g. on icy
or loose surfaces). In this case, the vehicle
can slip.
f Always adjust your driving style to the driving
conditions and vehicle load. Use the footbrake
if necessary.
If the Drive-Off Assistant is not functioning,
the driver cannot be assisted when driving
off on hills.
f Hold the vehicle with the footbrake.

Driving and Driving Safety
“Sport” and “Sport Plus” Mode FunctionThe selectable chassis settings mean that the
vehicle can offer various modes for a sportier
overall setup.
When “Sport” or “Sport Plus” mode is selected, all
the vehicle’s control systems are intentionally
shifted towards greater agility and driving
performance:
– PASM (Porsche Active Suspension Management) is automa tically changed to
“PASM Sport” or “PASM Sport Plus” mode,
resulting in a stiffer suspension setup.
The vehicle switches to Low Level in “PASM
Sport Plus” mode.
f Please see the chapter “PORSCHE ACTIVE
SUSPENSION MANAGEMENT (PASM)” on
page 208.
– Just like PASM, PDCC is switched to the corresponding “Sport” or “Sport Plus” mode,
whereby the rolling movements of the vehicle
are reduced further, depending on the
selected mode.
f Please see the chapter “PORSCHE DYNAMIC
CHASSIS CONTROL (PDCC)” on page 211.
– The PDK transmission switches to a sporty gear-changing map and shortens the gear
shifting times when Sport mode is activated.
Gear changes take place faster. f
Please see the chapter ““SPORT” AND “SPORT
PLUS” MODE” on page 195.
– The electronic accelerator pedal reacts sooner, and the engine is more responsive to
throttle inputs. When Sport mode is switched
on and the vehicle is travelling at a speed of
less than 25 mph (40 km/h), this function is
activated only after the driver has floored the
accelerator pedal or released it briefly.
– The rpm limiter characteristic is “harder”. In other words: the engine is immediately
throttled when the performance limits are
reached (only in manual selection mode on
vehicles with PDK).
– The turbo overboost briefly increases the engine boost pressure in the engine speed
range from 2,500 rpm to approx. 4,000 rpm.
As a result, torque in this speed range is
increased by 70 Nm (52 ftlb.). This
considerably improves acceleration and
flexibility, particularly in the medium engine
speed range. This does not affect the
maximum power. Quickly flooring the
accelerator pedal acti vates turbo overboost
in the engine control system. Overboost has
an effective operating time of approx.
10 seconds. After this time, it can be re-
activated by quickly flooring the accelerator
pedal again. – PSM (Porsche Stability Management) control is
more sporty in “Sport Plus” mode. PSM
interventions are later than in Normal mode.
The driver can maneuver the vehicle with
greater agility at it s performance limits,
without having to dispense with the assistance
of PSM in emergency situations. This helps to
achieve optimal lap times, particularly on race
circuits with a dry road surface.
f Please see the chapter “PORSCHE STABILITY
MANAGEMENT (PSM)” on page 202.
– Adaptive cruise control regulates speed and distance more dynamically.
– The Auto Start Stop function is deactivated.
f Please see the chapter “AUTO START STOP
FUNCTION” on page 169.
– The rear spoiler extends earlier and retracts later (“Sport Plus” mode only).
f Please see the chapter “RETRACTABLE REAR
SPOILER” on page 214.
– The system switches from High Level.
f Please see the chapter “HIGH LEVEL” on
page 209.

Maintenance and Car Care
High-pressure cleaning equipment
Warning!
High-pressure cleaning equipment can
damage the following components:
–Tires
– Logos, emblems, decorative foils
– Painted surfaces
– Alternator, valve covers
– ParkAssist sensors
– Radar sensor for adaptive cruise control
– Rearview camera
f Always read the operating instructions
provided by the equipment manufacturer.
f Always cover the lid of the brake fluid reservoir
prior to cleaning. Never point the cleaning jet
directly at the lid.
f When cleaning with a flat-jet nozzle or
a so-called “dirt blaster”. maintain a minimum
distance of 20 in. (50 cm).
f Never use high-pressure cleaning equipment
with a round-jet nozzle.
A high-pressure cleaning device fitted with
a round nozzle will damage your vehicle. The
tires are particularly susceptible to damage.
f Do not point the cleaning jet directly at any of the aforementioned components.
Decorative film
Caution!
Risk of damage due to separation of the
decorative film when using high-pressure
cleaning equipment.
f When cleaning components, the water must
not be hotter than 140 °F (60 °C) and the
pressure no greater than 580 psi (40 bar).
Always observe a minimum distance of 20 in. (50 cm).
Care of door lockfTo prevent the door lock from freezing
during the cold season, cover the lock barrel
with suitable adhesive tape while washing
the vehicle.
If the lock still freezes, use an ordinary de-icer.
In many cases, a well warmed key can help.
Never use excessive force.
Car washingThe best protection for the vehicle from the
damaging effects of the environment is frequent
washing and preservation.
The longer road salt, road dust, industrial dust,
insect remains, bird excrement, and tree sap,
resin, pollen, etc. are allowed to remain on the
bodywork, the more harmful their effect.
Observe the following poi nts in order to ensure
that the vehicle is washed thoroughly without
damaging the paintwork:
f The underside of the vehicle should also be
thoroughly washed at the end of the winter
season at the latest.
f Wash your vehicle only at sites provided for
this purpose to prevent soot, grease, oil and
heavy metals from entering the environment.
f Dark colors are slightly more susceptible
to scratching and require particularly careful
paint care.
Dark paints make even the smallest surface
blemishes (scratches) more conspicuous than
lighter colors.
f Do not wash your Porsche in direct sunlight
or when its body is hot.
f When washing by hand, use a car shampoo,
plenty of water, and a soft sponge or washing
brush.
We recommend Porsche car shampoo.

274
Maintenance and Car Care
Cleaning headlights, lights, interior and
exterior plastic components, adhesive
foils, radar sensor for adaptive cruise
control and rearview cameraObserve the following points:
fUse only clean water and a little dishwashing
liquid or interior window cleaner to clean
headlights, lights, plastic components
and surfaces.
Use a soft sponge or a soft, lint-free cloth.
Note
An interior window cleane r can also be used to
clean plastic surfaces (always read the cleaning
instructions on the container!).
We recommend Porsche interior window cleaner.
f Gently wipe the surface without applying
too much pressure.
f Do not clean when dry.
f Never use other chemical cleaners
or solvents.
f Rinse cleaned surfaces with clear water.
Alloy wheelsMetal particles (e.g. brass or copper in brake
dust) must not remain too long on alloy wheels.
Contact corrosion can cause pitting.
Note
Cleaners with an oxide-removing effect or
wrong pH value, as are commonly used for
other metals, as well as mechanical tools and
products, will damage the oxide layer and are
therefore unsuitable.
fUse only cleaners for alloy wheels
(pH value 9.5). Products with the wrong
pH value can destroy the protective layer
on the wheels.
We recommend Porsche cleaner for light
alloy rims.
f If possible, wash the wheels every two weeks
with a sponge or washing brush. If the wheels
are exposed to road salt, grit or industrial dust,
weekly cleaning is necessary.
f Every three months, after cleaning, treat the
wheels with car wax or an acid-free grease
(e.g. Vaseline).
Rub the grease in well with a soft cloth.
f Please see the chapter “CLEANING IN CAR
WASHES” on page 271.
Danger!
Danger of accident resulting in serious
personal injury or death if cleaning agents
(e.g. wheel cleaning agents) come into
contact with the brake discs. The resulting
film on the brake discs can impair braking
performance.
f Make sure that no clea ning agent comes into
contact with the brake discs.
f If cleaning agent has come into contact with
the brake discs, clean the brake discs
thoroughly with a strong jet of water.
f Paying attention to any road users behind you, dry the brake discs by applying the brakes.
Stainless steel tailpipesStainless steel tailpipes can discolor due to
soiling, strong heat and combustion residues.
The original shine can be achieved again using
commercially available metal lustre paste or metal
polish.
