For vehicles with both CC and ACC
–
Change a set speed by pressing the (1)
or
(3) buttons briefly or by pressing and
holding them:
•
Press briefly: Press briefly: each press
changes the speed in +/- 5 mph
(+/- 5 km/h) increments.
•
Press and hold: release the button when
the set speed indicator (4) has moved to
the desired speed.
•
The most recently set speed will be stored.
If speed is increased by depressing the accelera-
tor pedal while pressing the
(1) button on
the steering wheel, the vehicle's speed when the
button is pressed will be stored as the set speed.
Temporarily increasing speed using the accelera-
tor pedal, e.g. when passing another vehicle, will
not affect the setting. The vehicle will return to
the set speed when the accelerator pedal is
released.
Using engine braking instead of
applying the brakes
Cruise Control regulates speed by lightly applying
the brakes. On downgrades, it can sometimes be
desirable to roll a bit faster and let speed be
reduced instead by engine braking alone. The
driver can temporarily disengage the Cruise Con-
trol braking function.
To disengage CC:
–
Press the accelerator pedal about halfway
down and then release it.
> Cruise Control will automatically disen-
gage the automatic brake function and
speed will only be reduced using the
engine braking function.
How drive mode affects cruise control
The way the cruise control maintains the vehicle's
speed can vary depending on the selected drive
mode
26
.
Cruise Control Eco Cruise with ECO drive
mode
In the ECO drive mode, cruise control's accelera-
tion and deceleration will be smoother than in
other drive modes to help provide optimal fuel
efficiency and reduced environmental impact.
Because of this, the vehicle's actual speed may
be slightly above or below the set speed.
For more information, see "ECO drive mode"
under "Eco Cruise".
Cruise Control Dynamic Cruise
With the Dynamic drive mode, cruise control's
acceleration and deceleration will be faster and
more immediate than in other drive modes.
