Approach grades as you would normally, with the appropriate gear
selected and at a safe speed.
Cruise control should NOT be used on downhill grades.
You should use appropriate gearing and brake techniques on downhill
grades.
When the system detects brake overuse – depending on the vehicle
manufacturer – a text message will be displayed on the dashboard and
an audible alert will be activated. You should intervene immediately.
• Once the brake overuse alert is activated, certain driver interventions that
cancel cruise control – such as stepping on the brake pedal or switching
off cruise – will discontinue the alert. Following an overuse alert, you
should not reset cruise control for at least 20 minutes. This gives the
brakes time to cool down.
If you choose to reset cruise control during that 20 minute period, Bendix

system interventions will be limited to de‑throttling
and engine retarder only. The system will automatically disable all
Wingman Fusion system foundation brake applications for at least 20
minutes.
• If the system does not detect a driver intervention within 15 seconds after
the brake overuse alert sounds, it will shut itself off and set a Diagnostic
Trouble Code (DTC). You will continue to receive alerts, but ALL Wingman
Fusion interventions (de‑throttling, engine retarder or brake applications)
will be disabled until the next ignition cycle.
NOTE: In all cases, you still have the ability to apply the foundation brakes
if necessary. You should take care since overheated brakes may reduce
the vehicle’s braking capability.
