Managing Cruise Control speedCruise Control (CC 29
) can be set to various
speeds.
Setting/changing set speed
Note: This illustration is general and details may vary depending on model.
For vehicles with only CC
–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 +/- 1 mph (+/- 1 km/h) increments.
• Press
and hold: Release the button when
the set speed indicator (4) has moved tothe 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, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
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 tothe 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 tothe set speed when the accelerator pedal isreleased.
Using engine braking instead of
applying the brakes
Cruise Control regulates speed by lightly applyingthe brakes. On downgrades, it can sometimes bedesirable to roll a bit faster and let speed bereduced instead by engine braking alone. Thedriver 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 theengine braking function.
How drive mode affects cruise controlThe way the cruise control maintains the vehicle'sspeed can vary depending on the selected drive mode 30

Cruise Control Eco Cruise
In the ECO drive mode, cruise control's accelera- tion and deceleration will be smoother than inother drive modes to help provide optimal fuelefficiency and reduced environmental impact.Because of this, the vehicle's actual speed maybe slightly above or below the set speed.
Cruise Control Dynamic Cruise
With the Dynamic drive mode, cruise control's acceleration and deceleration will be faster andmore immediate than in other drive modes.

Deactivating and putting CruiseControl in standby mode
Cruise Control (CC 31
) can be temporarily put
into standby mode and then reactivated.

> The Cruise Control markings and symbols will change from WHITE to GRAY, indicat- ing that Cruise Control is temporarilydeactivated and the driver needs to con-trol the vehicle's speed.
Standby mode due to action by the driver
Cruise Control will be temporarily deactivated and put in standby mode if:
• the brakes are applied
• the gear selector is moved to
N
• the vehicle is driven faster than the setspeed for more than 1 minute
The driver must then control the vehicle's speed. Temporarily increasing speed using the accelera- tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
Automatic standby mode
Cruise Control will be temporarily deactivated and put in standby mode if:
• the wheels lose traction
• the engine speed (rpm) is too low/high
• the temperature in the brake systembecomes too high
• the vehicle's speed goes below 30 km/h(20 mph).
The driver must then control the vehicle's speed.
