Towing And Tow-Starting - Porsche 718 Cayman GT4 Owner's Manual

Towing and Tow-Starting

Information
e Always observe the legal requirements relating to
the towing and tow starting of vehicles. Certain
state statutes and local ordinances prohibit
towing with a chain, rope or even a tow bar. In
addition, damage to your vehicle may result from
improper precedures.
e Vehicles should only be towed with great care.
Before driving, both drivers should familiarize
themselves with the special conditions that apply
to tow-starting and towing.
e In the event of a power failure or faults in the
electrical system, it may be necessary to connect
an external power supply in order to release the
electric parking brake or the steering column lock.
Tow starting and push starting the
vehicle
e Vehicles with Porsche Doppelkupplung (PDK)
cannot be tow-started or push-started, nor must
this be attempted due to the risk of serious
damage to the transmission.
e Vehicles with manual transmissions may only be
tow started or push started when the engine is
cold. If the engine is warm, unburnt fuel could
damage the catalytic converter.
Using tow rope or tow bar
e Data and installation instructions can be found in
the accessory manufacturer's manual. Follow the
manufacturer's safety and operating instructions.
e Observe the permissible towing force of the
towing rope or towing bar. The tow rope or tow
bar must be approved for the vehicle weight.
Never exceed the manufacturer's specifications.
e Vehicles with defective brakes must not be
towed.
Using a tow rope
e When towing a vehicle, first screw the towing
hook into the vehicle before attaching the tow
rope to the towing hook.
f Please see chapter „Attaching the towing hook"
on page 228.
e Always keep the towing rope taut when towing.
Avoid jerky and sudden loading.
Using a tow bar
e The tow bar should not be attached diagonally
between the vehicles.
Towing the vehicle
Increased Steering and
WARNING
Braking Forces due to a
Lack of Power Assistance
There is no power steering on the towed vehicle
when the engine is not running. This means that
greater force is required for braking and steering.
e Vehicles should only be towed with great care.
The towed vehicle must not be heavier than the
towing vehicle.
It is not possible to guarantee that the transmission
is sufficiently lubricated when the engine is not
running. The following points have to be noted in
order to prevent damage to the transmission.
Special feature on vehicles with PDK
e The vehicle must not be towed when the Porsche
Doppelkupplung (PDK) transmission is in
emergency operation mode (warning message
indicates transmission failure) or if a selector
lever emergency release was performed. It has to
be transported on a transport truck or flatbed
trailer.
