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.
See “Road Sign Information limitations” for moreinformation.

For vehicles with both CC and ACC
–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 +/- 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.
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.

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.
