Precautions when the TDA (Trailer
Driving Assist) is used
TDA (Trailer Drive Assist) is a system that
adjusts certain driver assist settings to sup-
port towing functionality. It is recom-
mended to use a genuine trailer brake
controller (P.468) when towing. Towing
without a genuine trailer brake controller
increases the risk of vehicle/trailer instabil-
ity.
There are limitations to this system. Do
not overly rely on the system. The driver
is solely responsible for paying attention
to the vehicle’s surroundings and driving
safely.
For the correct trailer towing procedure:
see P.191.
