significantly drop speed when driving uphill,
especially with a heavy load. If the speed drops
more than 8 to 14 mph (15 - 25 km/h) the

manual speed control while driving up a steep

If the speed control “dropped out” after your
climb is completed, the speed of your vehicle
can be reset with the SET ACCEL switch, or
returned to the previous set speed with the
RESUME switch, as long as you are driving over
30 mph (50 km/h).
