2006 PORSCHE 911 CARRERA snow chains

Controls, Instruments
73
Examples of PSM control operations
– If the front wheels of the vehicle drift on a
bend, the rear wheel on the inside of the bend
is braked and the engine power is reduced if
necessary.
– If the rear of the vehicle swings out on a bend,
the front wheel on the outside of the bend is
braked.
Additional functions for vehicles with
four-wheel drive
– Pre-filling the brake system:
If you suddenly and quickly take your foot off
the accelerator pedal, the brake system gets
prepared for possible emergency braking. The
brake system is pre-filled which lightly presses
the brake pads on the brake discs.
Brake boost:
If emergency braking does not have sufficient
pedal pressure, the brake boost produces
the brake pressure necessary for maximum decel-
eration on all 4 wheels.The PSM should always be switched on
during “normal” driving.
However, it may be advantageous to switch off
PSM temporarily in exceptional situations, for
example:
– On a loose surface or in deep snow,
– When “rocking the vehicle free” and
– When using snow chains.
Switching off PSMfPress PSM OFF button.
PSM is switched off after a short delay.
The light-emitting diode in the button is illumi-
nated.
When the PSM is switched off, the multifunc-
tional PSM light on the instrument panel is lit
and a message is shown by the on-board
computer. An acoustic signal also sounds.
Vehicles with four-wheel drive
When PSM is switched off, the additional braking
functions are deactivated. The automatic reactiva-
tion in emergency situations is coupled to the PSM
control in emergency situations.

Practical Tips, Emergency Service

Snow chains
Caution!
Risk of damage to body, axle or brake com-
ponents.
fFit snow chains only to the rear wheels, and
only with the tire/rim combination listed in the
Technical Data.
To ensure adequate clearance between chain
and body, Porsche recommends only the use
of fine-link chains such as those approved by
Porsche.
fFollow instructions issued by the supplier of the chains.
Different states and countries have varying statu-
tory requirements regarding maximum speed.
Check with local authorities for possible restric-
tions.
fRemove chains as soon as the roads are free
of ice and snow. 911 Carrera, 911 Carrera S
Fitting snow chains
The use of snow chains is not permitted when
5 mm spacers are mounted.
Caution!
Risk of damage to the wheel housings if the
5 mm spacers are not removed before fitting
snow chains.
fTo permit the fitting of snow chains, have the 5 mm spacers removed on all 4 wheels.
fTo fit/remove the spacers:
Please consult an authorized Porsche dealer.
fPlease observe the chapter “5 MM SPACERS”
on Page 253.
Tire designations Due to new speed and load ratings for radial tires,
new designations have come into force for snow
tires for your Porsche.
The designation to be used for ZR tires is e.g.,
265/40 ZR 18 (Z = code letter for radial tires for
speeds above 150 mph / 240 km/h).

Practical Tips, Emergency Service
249
SpacersfUse the spacers only together with wheels and
fastening parts approved by Porsche.
Before having spacers fitted, find out about the
current approval status.911 Carrera 4, 911 Carrera 4S
Danger!
Risk of accident.
17 mm spacers must only be mounted on the
rear axle together with 11.5 J x 19 (67 mm
rim offset) wheels.
fAlways remove 17 mm spacers before
mounting other wheel sizes or an emergency
spare wheel because the wheel cannot be mounted correctly.
911 Carrera, 911 Carrera SMounting an emergency spare wheel
If 5 mm spacers are mounted, these must not be
removed to mount an emergency spare wheel.
Fitting snow chains
The use of snow chains is not permitted when
5 mm spacers are mounted.
Caution!
Risk of damage to the wheel housings if the
5 mm spacers are not removed before fitting
snow chains.
fTo permit the fitting of snow chains, have the 5 mm spacers removed on all 4 wheels.Note on operation
fTo fit/remove the spacers:
Please consult an authorized Porsche dealer.

f To permit the fitting of snow chains, have the 5 mm spacers removed on all 4 wheels.
f To fit/remove the spacers:
Please consult an authorized Porsche dealer. Removing the spacers
1. Unscrew both countersunk screws (M6x16) on
the wheel hub.
2. Remove the spacer.
3. Fasten the brake disc with the short M6x12
countersunk screws, part No.:
900.269.047.09.
Tightening torque 10 Nm (7.5 ftlb.) .
4. For wheel mounting without a spacer, 5 mm
shorter wheel bolts (part No.:
996.361.203.02) must be used.
Tightening torque: 130 Nm (96 ftlb.) .f
Please observe the chapter “CHANGING A
WHEEL” on Page 250.

Snow chainsCan be mounted only on the rear wheels; maximum speed 30 mph (50 km/h).
Use only Porsche authorized fine-link cross-type or edge chains.
Snow chain clearance can be guaranteed only on the tire + rim combination marked** without spacers.
Tire and rim sizesExtensive tests are performed before specific tires and wheels are approved by Porsche. Your Porsche dealer has informa-
tion about approved tires and wheels and is happy to assist you.
If aftermarket tires and/or wheels are installed which are not approved by Porsche, the vehicle’s roadability and handling
characteristics might be impaired. Since Porsche has no data on such combinations, Porsche cannot stand behind the safe-
ty or durability of these aftermarket combinations.
