Driving your vehicle

Driving your vehicle18 4The cruise control system allows you to
program the vehicle to maintain a con-
stant speed without resting your foot on
the accelerator pedal.
With cruise control, you can set and
automatically maintain any speed of
between 40 km/h (24 mph) and
160 km/h (96 mph).
To set cruise control speed:1. Pull the CRUISE ON/OFF button on
the steering wheel, to turn the system
on. The CRUISE indicator light in the
instrument cluster will illuminate.
2. Accelerate to the desired speed, which
must be more than 40 km/h (24 mph)
and less than 160 km/h (96 mph).3. Press the COAST/SET switch, located
on the steering wheel, and release it at
the speed you want. Release the accel-
erator at the same time. The desired
speed will automatically be maintained.
The SET function cannot be activated
until approximately 2 seconds after the
CRUISE ON/OFF button has been
engaged.
On a steep grade, the vehicle may
momentarily slow down while going
downhill.
