TOW BARS Towing
Only fit towing accessories that have been approved by MG
Rover, otherwise serious damage to the car may result.
To ensure absolute safety, only fit accessories that have been
designed and tested for your car. Your MG Rover dealer will
provide details of approved tow bars.
The permissible maximum towing weight, the maximum rear axle
weight and towing hitch downward load and the maximum
towing hitch overhang, are given in 'Technical Data'. In the interest
of safety, these must not be exceeded.
DO NOT use the rear lashing point for towing purposes -
serious damage to the car may result.
Tow bar mounting points
The tow bar is attached to the vehicle body NOT the chassis
and fitment requires specialised skills and knowledge. It is
therefore essential that only a tow bar approved for use with your car
is fitted and that it is fitted by qualified personnel.
The following information locating the mounting points is for
reference only and does not include details of the tow bar
installation process. The mounting points shown are for the
installation of an approved tow bar - no other means of attaching
a tow bar should be used.
The illustration shows the bumper assembly removed: the upper
view shows the four underside mounting points, the lower view
shows the rear mounting points.
