Danger of injury. During braking, direction
changes or in an accident, an unsecured
load can slip and endanger the occupants.
fAlways secure the passenger compartment
with the luggage safety net.
fAlways fasten the load at the tie-down rings.
fThe load must never project over the top edge
of the seat backrest.

Roof Transport SystemfPlease follow the separate instructions for
fitting the Roof Transport System.
fPlease observe the chapter “LOADING INFOR-
MATION” on Page 195.
Fitting normal commercially available luggage
racks is not possible.
ThePorsche Roof Transport System allows the
transport of various sports and hobby equipment.
Your authorized Porsche dealer will be pleased to
tell you about the manifold uses of the Roof Trans-
port System.
Warning!
Risk of an accident, loss of control and dam-
age to the vehicle.
fCompletely remove the Roof Transport System
before using an automatic car wash – risk of
damage to the vehicle.
fDo not exceed the permissible roof load, the
permissible gross weight and the permissible
axle loads.
Please observe the chapter “WEIGHTS” on
Page 363.
fDistribute load evenly, with heavy items as low
as possible. Items of luggage must not project
beyond the side of the load area.
fFix and secure every item to the basic carrier
with a rope or lashing strap (do not use elastic
rubber tensioners).
fBefore every journey, and at regular intervals
during long trips, check that Roof Transport
System and load are secure. Re-tighten if
necessary and secure additionally by locking.When the Roof Transport System is loaded, the
maximum speed depends on the nature, size and
weight of the load being carried.
fBut never drive faster than 90 mph
(140 km/h).
fWith the basic carrier fitted and no load, do not
exceed a maximum speed of 110 mph
(180 km/h).
Adapt your driving style and speed to the changed
conditions.
Nevertheless, Porsche recommends that you do
not exceed the posted speed limit.
Driving, braking and steering behavior change due
to the higher center of gravity and the greater
wind-resistant area. You should adapt your driving
style appropriately.
fSince fuel consumption and noise are in-
creased with the Roof Transport System fitted,
it should not remain on the car if not in use.

Stowing load in the vehicle
Warning!
Danger of injury.
An unsecured or incorrectly positioned cargo
can slip out of place or endanger the vehicle
occupants during braking, direction changes
or in accidents.
Never transport objects which are not se-
cured.
fAlways transport cargo in the cargo area, nev-
er in the passenger compartment (e.g. on or in
front of the seats).
fSupport the cargo on the seat backrests when-
ever possible. Always lock the backrests into
place.
fPlace the cargo behind unoccupied seats
whenever possible.
fStow heavy objects as close to the front of the
cargo area as possible, with lightweight ob-
jects behind them.
fThe cargo must never project over the top
edge of the seat backrest.
fAlways protect the passenger compartment
with a luggage safety net and a luggage
compartment cover.
Do not drive with objects on top of the luggage
compartment cover.fIf the rear seats are not occupied, the back-
rests can be additionally secured with the safe-
ty belts. Simply cross the outer safety belts
and insert each into the opposite buckle.
fMake sure that the cargo cannot damage the
heating filaments of the rear window and the
TV antenna of the side window.
Luggage net
fLuggage must be stowed completely covered
by the luggage net.
The luggage net can prevent only lightweight
objects from slipping.
Tie-down belts
fDo not use elastic belts or straps to tie down
cargo.
fDo not place belts and straps over sharp edg-
es.
fObserve the directions for use and information
for the tie-down equipment.
fUse only belts with a tear strength of at least
1543 lbs. (700 kg) and a maximum width of
1in. (25mm).
fCross the belts over the load.Driving
fThe car's handling changes depending on the
vehicle loading. Adapt your driving style to the
changed driving behavior.

the axle load.
fPlease observe the chapter “WEIGHTS” on
Page 363.
fNever drive with the rear window or rear lid
open.

Towing a trailer
Warning!
Driving with a trailer
fAlways observe the permissible towing capac-
ity, vertical coupling load and rear-axle load.
Please observe the chapter “WEIGHTS” on
Page 363.
fWhen connected, the trailer must always be
horizontal behind the towing vehicle. If neces-
sary, use a trailer with an adjustable drawbar.
fWhen the vehicle is driven in the mountains, the
engine output decreases as altitude increases.
The maximum weights stated are the values at
sea level. The total permissable weight of the
car-trailer combination must therefore be re-
duced by 10% for each increment of 3,280 ft.
(1,000 meters) altitude. A fractional increment
counts as the full 3,280 ft. (1,000 meters).
Please take this into consideration when plan-
ning your route.Distributing the load
fDistribute the load in the trailer so that heavy
objects are as close to the axle as possible.
Always safeguard all objects against slipping
and tie them down securely.
fYou should make the best possible use of the
trailer coupling's rated vertical coupling load
when loading the trailer, but never exceed it.
Tire pressure
fSelect the vehicle tire pressure for full load
when towing a trailer.
fPlease observe the chapter “Tire pressure ta-
bles”.
fCheck the tire pressure of the trailer's wheels
according to the manufacturer's instructions.Door mirrors
fIf the width of the trailer obstructs your view of
the traffic behind the trailer, you must have ad-
ditional door mirrors fitted.
Headlights, lights
fAlways check the headlight adjustment before
driving with a trailer.
If necessary, correct with the headlight beam
adjustment function.
fCheck whether the plug of the trailer is
plugged into the towing vehicle and whether all
lights function.

Shifting Gear, Traction Systems

M - Manual selection mode (in the road
driving program)The functions of selector lever positions Dand M
differ in the on-road program, High Range, and in
the off-road program, Low Range.
The currently selected gear is retained if you
change from D to M.
If you change from M to D, the gear-changing map
suitable for your current driving style is selected
and the appropriate gear is selected.
Warning!
The kickdown function is not active in manual
selection mode “M“.
The kickdown function cannot be used to
downshift in manual selection mode “M“.
fTherefore shift down manually when accelerat-ing (e.g. to overtake).
Shifting up
fPress upper part (+) of a rocker switch Aor
fPush selector lever B forward in the M gate.Shifting down
fPress lower part (–) of a rocker switch Aor
fPush selector lever B back in the M gate.
Depending on driving speed and engine speed,
you can shift up or down at any time. Gear chang-
es which would exceed the upper or lower engine-
speed limit are not executed by the control unit.
You can change down two gears by quickly press-
ing rocker switches A or selector lever B twice.
If PSM is active and the engine-speed limit is
reached, an automatic upward shift is performed
or, just before idling speed is reached, a down-
ward shift is performed.
fSelect an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking.
If manual mode fails, the control electronics
switch to automatic mode.
In this event, the instrument panel will display se-
lector lever position D.
fTo remedy the fault, please consult an autho-
rized Porsche dealer.
