To decrease the set speed
There are 2 ways to decrease the set speed.
“COAST SET” switch
Press and hold the “COAST SET” switch (B) while driving at the set speed, and your speed will slow down gradually.
When you reach your desired speed, release the switch. Your new cruising speed is now set.
To slow down your speed in small amounts, press the “COAST SET” switch for less than about 1 second and release it.
Each time you press the “COAST SET” switch, your vehicle will slow down by about 1.6 km/h (1 mph).
While driving at the set speed, use the brake pedal, which disengages the cruise control, then press the “COAST SET” switch (B) and release the switch momentarily to set a new desired cruising speed.
