Storing and maintaining the currentspeed
You can store the current speed if you are driving faster than 20 mph (30 km/h).
► Accelerate the vehicle to the desired
speed.
► Briefly press the cruise control lever
up 1 or down 2 to the pressure point.
► Remove your foot from the accelerator
pedal.
Cruise control is activated. The vehicle automatically maintains the stored speed.
Cruise control may be unable to maintain
the stored speed on uphill gradients. The
stored speed is resumed when the gradient
evens out. Cruise control maintains the stored speed on downhill gradients by
automatically applying the brakes.
