Cruise Control limitations
On steep downgrades, the Speed limiter's brak-ing capacity may not be sufficient and the setmaximum speed may be exceeded. If this hap-pens, Speed limit exceeded will be displayed inthe instrument panel to alert the driver.

NOTE
A text message on exceeded max. speed isactivated if the speed is exceeded by at least3 km/h (ca 2 mph).

Automatic Speed Limiter
The Automatic Speed Limiter (ASL) functionhelps the driver adapt the vehicle's maximumspeed to the posted speed limits.
The Speed Limiter (SL14) function can beswitched to Automatic Speed Limiter (ASL).
The Automatic Speed Limiter function usesspeed information from the Road Sign Informa-tion function (RSI) to automatically adapt thevehicle's maximum speed.

Automatic Speed Limiter limitations
Automatic Speed Limiter (ASL) utilizes the
speed limit information provided by the RSI18
function, not from the speed limit signs that thevehicle passes.
If RSI18 is unable to interpret and provide ASLwith speed information, ASL will go into standbymode and switch over to SL. The driver will thenhave to actively brake to bring the vehicle downto the appropriate speed.
ASL will be reactivated when RSI18 is once againable to interpret and provide speed information toASL.

Setting/changing set speed
Note: This illustration is general and details may varydepending on model and market.

For vehicles with only CC
–Change a set speed by pressing the (1)
or (3) buttons briefly or by pressing andholding them:
Press briefly: Press briefly: each presschanges the speed in +/- 1 mph(+/- 1 km/h) increments.
Press and hold: release the button whenthe 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 onthe steering wheel, the vehicle's speed when thebutton 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.

or (3) buttons briefly or by pressing andholding them:
Press briefly: Press briefly: each presschanges the speed in +/- 5 mph(+/- 5 km/h) increments.
Press and hold: release the button whenthe set speed indicator (4) has moved tothe desired speed.
The most recently set speed will be stored.

tor pedal while pressing the (1) button onthe steering wheel, the vehicle's speed when thebutton 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.

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 halfwaydown and then release it.
> Cruise Control will automatically disen-gage the automatic brake function andspeed will only be reduced using theengine braking function.
How drive mode affects cruise control
The way the cruise control maintains the vehicle'sspeed can vary depending on the selected drive
mode22.

Cruise Control Eco Cruise with ECO drive
mode
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'sacceleration and deceleration will be faster andmore immediate than in other drive modes.

Standby mode due to action by the driver
Cruise Control will be temporarily deactivated andput 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 andput 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.
