Increasing Speed While Using Cruise Control

If the cruise control system is already activated:

• Press and hold the +RES button on the steering wheel until the desired speed is reached, then release it.

• To increase vehicle speed in small increments, press the +RES button briefly. Each time this is done, the vehicle goes about 1.6 km/h (1 mph) faster.
