Towing And Tow-Starting - Porsche 911 Turbo Manual

Towing and Tow-Starting

Warning!
Risk of accident. No servo assistance is
available on the towed vehicle when its
engine is not running. Greater force is there-
fore necessary when braking and steering.
The ABS and PSM do not operate if this is the
case.
f Exercise great care when on tow.
f Switch on the ignition so that the brake lights
and direction indicator lights operate and the
steering lock cannot engage.
f Always keep the towing rope taut when towing.
Avoid jerky, sudden loads.
f Always observe the laws governing towing and
tow-starting.
Caution!
Risk of damage when towing due to small
ground clearance.
f When towing and when recovering with a
towing vehicle, pay attention to the small
ground clearance.
Tow-starting
If the battery is defective or completely
discharged, the engine can be started only by
changing the battery or by using jump leads.
f Please observe the chapter "JUMP LEAD
STARTING" on page 218.
Cars fitted with a catalytic converter may only be
tow-started when the engine is cold.
If the engine is warm, unburned fuel could damage
the catalytic converter.
Vehicles with Tiptronic
The vehicle cannot be tow-started, nor should this
be attempted due to the risk of serious transmis-
sion damage.
Towing
When being towed, the vehicle must have all four
wheels on the ground or it must be moved on a car
transporter or a trailer.
Any raising of an axle, irrespective of whether at
the front or rear, is only permissible if the drive
shaft (cardan shaft) has been removed before-
hand. The ignition must be off.
On vehicles equipped with Tiptronic, the trans-
mission will not be supplied with sufficient lubrica-
tion when the engine is at a standstill. The
following points must also be observed to avoid
damage to the transmission:
f Put selector lever in position N.
f Do not exceed the maximum speed of
50 km/h (30 mph). Maximum towing
distance 50 km (30 miles).
If a significant towing distance is involved, then
the vehicle must be raised at the rear axle and
the drive shaft (cardan shaft) removed.
