■ Trailer brake type setting
It is the responsibility of the driver to
make sure the trailer brakes are func-
tioning normally and adjusted appropri-
ately. Failure to check and maintain
trailer brakes may result in loss of vehicle
control, crash, or serious injury. Trailer
brake control system will work with most
electric and electric-over-hydraulic
trailer braking systems up to 3 axles
(24A output to trailer brakes). Please be
sure to test compatibility with the system
at low speeds and in a safe area. If a
warning message appears in the multi-
information display (P.623), have the
vehicle inspected by your Lexus dealer
immediately. Some electric- over-
hydraulic trailer brakes will take some
minimum output to activate. Trailer
brake control system will not work with
trailer hydraulic surge brakes.
