Loading InformationDefinitionsThe towing capacity (gross weight of the trailer)
is the sum of the trailer's empty weight and the
weight of the load.
The vertical coupling load is the weight that the
trailer drawbar exerts on the trailer coupling of the
vehicle.
The rear-axle load is the vehicle weight on the
rear axle plus the weight of the transported load
and the vertical coupling load of the trailer.
The gross weight of the vehicle and trailer is
the sum of the weight of the towing vehicle and the
weight of the trailer.
The Curb weight - actual weight of your vehicle -
vehicle weight including standard and optional
equipment, fluids, emergency tools, and spare tire
assembly. This weight does not include passen-
gers and cargo.
The Gross Vehicle Weight is sum of the curb
weight and the weight of passengers and cargo
combined.
The Gross Vehicle Weight Rating is the maxi-
mum total weight of vehicle, passengers, lug-
gage, hitch, trailer tongue load and optional equip-
ment.The Gross Axle Weight Rating is the maximum
load limit for the front or the rear axle. This infor-
mation is located on the safety comliance sticker
located in the driver’s side door jamb.
For determining the compatibility of the tire and
vehicle load capabilities:
fPlease observe the chapter “TIRES, RIMS,
TRACKS” on Page 358.
The load capacity coefficient (e.g. “106”) is a mi-
nimum requirement.
The Gross Combined Weight Rating is the
maximum total weight rating of vehicle, passen-
gers, cargo and trailer.
The Vehicle Capacity Weight - Load Limit - is
the maximum total weight limit specified of the
load (passengers and cargo) for the vehicle. This
is the maximum weight of passengers and cargo
that can be loaded into the vehicle. This informa-
tion can be found on the tire pressure plate.
If a trailer is being towed, the trailer tongue weight
must be included as part of the cargo load.
The maximum loaded vehicle weight is the
sum of curb weight, accessory weight, vehicle ca-
pacity weight and production options weight.
The load rating is the maximum load that a tire
is rated to carry for a given inflation pressure.
The maximum load rating is the load rating for
a tire at the maximum permissble inflation pres-
sure.The cargo capacity is the permissible weight of
cargo, the substracted weight of passengers from
the load limit.
fNever exceed the permissible limits.
Danger!
Risk of personal injury or death.
Injuries are much more likely in an accident
if persons ride in the cargo area.
fPersons must ride only on the seats provided
for this purpose.
fMake sure that everybody fastens their safety
belts.
Risk of personal injury, loss of control and
damage to vehicle.
fNever exceed the specified axle loads. Over-
loading can shorten the service life of the tires
and car, as well as lead to dangerous vehicle
reactions and long braking distances. Damage
due to overloading is not covered by the vehic-le warranty.

Closing spare wheel bracket
Warning!
Danger of injury and risk of accident if the
spare wheel bracket is operated improperly.
fOperate the spare wheel bracket only using
buttonB.
fIf the vehicle is tilted to the side, more effort
will be required to swing the spare wheel
bracket.
fMake sure that no persons or animals are
within the range of movement of the spare wheel bracket.
1. Check whether additional lock C is engaged. If
necessary, slide additional lock C to the right.
2. Swing spare wheel bracket closed with force.
3. Check lock and observe indication on the multi-
purpose display of the instrument panel.
The indicator light must go out when the spare
wheel bracket is locked.
Automatic locking
fPlease observe the chapter “TAILGATE” on
Page 104.

E- Emergency release cableEmergency release for the spare wheel
bracketIf the battery is flat, the only way to open the spare
wheel bracket is by using the mechanical emer-
gency release.
Warning!
Danger of injury and risk of accident if the
spare wheel bracket is operated improperly.
fPerform emergency unlocking of the spare
wheel bracket only when the vehicle is on a level surface.
1. Remove cover of left towing lug D.
2. Pull emergency release cable E in the direction

Emergency Starting with Jumper
CablesIf the battery is discharged, e.g. in winter or after
the car has been parked for a long time, the bat-
tery of another car can be used for starting with
the help of jumper cables.
Make sure the voltage of both batteries is the
same.
The capacity (Ampere hours, Ah) of the booster
battery must not be substantially less than that of
the discharged battery.The discharged battery
must be correctly connected to the vehicle's elec-
trical system.
fPlease observe the chapter “BATTERY” on
Page 320.
Note
Do not try to start the car by pushing or towing.
Damage to the catalytic converters and other
components of the car may result.
Danger!
Risk of damage and serious personal injury
due to short circuit.
fUse only jumper cables of adequate diameter
cross-section and fitted with completely insu-
lated alligator clips.
fFollow all warnings and instructions of the
jumper cable manufacturer.
fWhen connecting jumper cables, make sure
that they cannot get caught in any moving
parts in the engine compartment.
The jumper cables must be long enough so
that neither vehicles nor cables touch another.
fThe vehicles must not be in contact, otherwise
current might flow as soon as the positive ter-
minals are connected.
fThe cable clamps must not be allowed to con-
tact each other when one end of the jumper ca-
bles are connected to a battery.
fCarefully ensure that tools or conductive jewel-
ery (rings, chains, watch straps) do not come
into contact with the positive jumper cable or
the positive battery post.
fImproper hook-up of jumper cables can ruin
the alternator.
Danger of caustic burns.
fDo not lean over the battery.Danger of gas explosion.
fImproper use of booster battery to start a ve-
hicle may cause an explosion, resulting in se-
vere personal injuries.
fKeep sources of ignition away from the bat-
tery, e.g. open flame, burning cigarettes or
sparking due to cable contact or welding work.
fA discharged battery can freeze even at
14°F (10°C). Before connecting jumper ca-
bles, a frozen battery must be thawed out.

Practical Tips, Minor Repairs
TowingCertain state statutes and local ordinances prohib-
it towing with a chain, rope or even a tow bar. In
addition, damage to your vehicle may result from
improper procedures. Consult your authorized
Porsche dealer for details.Vehicle towingFlat bed towing is the preferred type of towing to
be used on Porsche vehicles. Under certain cir-
cumstances, wheel lifts may be used when the ve-
hicle will not roll.
The vehicle must be towed with all four
wheels off the ground, otherwise damage to
the vehicle may result.Towing hookThe towing hook is contained in the tool kit.
Caution!
Risk of damage to the vehicle.
fUse the towing hook only for an emergency to
remove the vehicle off the road. The towing
hook is to be used only to pull the vehicle onto
the flat bed, tractor or towing aparatus if the
vehicle will roll freely. Under no circumstances
is the vehicle to be secured using the towing
hook.
fNever use the towing hook to tow this or any other vehicle.
Vehicles with Tiptronic
fDo not tow-start vehicles with a Tiptronic
transmission.
The vehicle cannot be tow-started, nor should
this be attempted due to the risk of serious
transmission damage.
Vehicles with manual transmission
Only tow-start vehicles fitted with a catalytic con-
verter when the engine is cold.
If the engine is warm, unburned fuel could damage
the catalytic converter.Front and rear mounting
1. Carefully lever out the appropriate plastic cov-
erA in the bumper with the screwdriver.
The cover is captive and need not be removed
completely.
