Alfa Romeo STELVIO 2022 Owner's Handbook Manual page 186

Any electric brake must be powered
directly by the battery through a cable
with a cross-section of no less than
0.004 in² (2.5 mm²).
In addition to the electrical branches,
the car electrical system can only be
connected to the supply cable for an
electric brake and to the cable for
an internal light for the trailer, not
exceeding 15W. For connections use the
preset box with battery cable with cross-
section no less than 0.004 in² (2.5 mm²).
WARNING The use of auxiliary loads
other than external lights (e.g. electric
brake) must take place with engine
running.
WARNING Contact an Alfa Romeo
Dealership to install a tow hook.
WARNING
157) The ABS with which the car is equipped
will not control the braking system of the
trailer. Particular caution is therefore
required on slippery roads.
158) Never modify the braking system of
the car to control the trailer brake. The
towing braking system must be completely
independent of the vehicle's hydraulic
system.

TOW HOOK SETUP
Instructions for using the removable
ball head tow hook
WARNING Before setting off, check
that the removable ball head tow hook
is locked correctly. To do this, check the
following conditions:
the green mark on the knob must
coincide with the green mark on the tow
hook fixing bracket;
the knob must be at the end of its
travel, resting on the tow hook fixing
bracket (no crack);
the lock on the knob must be locked
with the key removed. The knob cannot
be removed;
the tow hook fixing bracket must be
firmly attached to the mounting pipe on
the car. Check by shaking with a hand.
The installation procedure must be
repeated if any of these requirements is
NOT met.
If even only one of the requirements is
not met the tow hook must not be used,
since there is risk of causing accidents.
Contact an Alfa Romeo Dealership.
The ball head tow hook can be
fitted/removed manually without the
need for specific tools.
WARNING Never use cars or work tools:
the mechanism may be damaged.
WARNING Do not release the tow hook
when it is attached to a trailer or cargo-
carrier.
WARNING When driving without trailer
(or without a cargo-carrier), the ball head
tow hook must be removed and the
closing cap must always be inserted in
the hook mounting pipe. This applies
particularly if the tow hook reduces
visibility of the number plate or the
lighting system.
For the electrical connection, a 13
pin 12VDC connection is to be used
(CUNA/UNI and ISO/DIN Standards).
Follow the instructions provided by the
car Manufacturer and/or the tow hook
Manufacturer.
Installing the tow hook
Before inserting the tow hook, you must
remove the access cover to the tow hook
fixing position under the rear bumper.
Remove the protection cap from the
tow hook mounting pipe fig. 209;
get the tow hook from the boot.
