The stored speed flashes in the
instrument cluster. When the
accelerator pedal is released, the
previously stored speed is resumed.
Cruise control remains activated
while gearshifting.
The speed is saved until the ignition
is switched off.
Increase speed
With cruise control active, the vehicle speed can be increased continuously
or in small increments by holding
down or tapping < repeatedly.
When the switch is released the
current speed is stored and
maintained.
Alternatively, accelerate to the
desired speed and store by pressing
< .Reduce speed
With cruise control active, the vehicle speed can be decreased

● selector lever in N
● engine speed is in a very low or very high range
The speed is stored and a
corresponding message appears in
the DIC.
Reactivation Press R at a speed above 20 mph.
If the stored speed is much higher
than the current speed, the vehicle
will accelerate powerfully until the stored speed is obtained.
Pressing < will also reactivate the
cruise control function, but at the
