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.

WARNING
The ASL function is supplementary driversupport intended to facilitate driving andhelp make it safer – it cannot handle allsituations in all traffic, weather and roadconditions.
Even if the driver can clearly see thespeed limit sign, the speed informationfrom the Road Sign Information (RSI)function to ASL may be incorrect. In suchcases, the driver must intervene andaccelerate or brake to an appropriatespeed.
ASL is not a substitute for the driver'sattention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.
See also the heading "Road Sign Infor-mation limitations".
Is SL or ASL active?
The symbols in the instrument panel indicatewhich Speed Limiter function is active:
SymbolSL ASL
A✓ ✓
Road sign symbolB after "70" = ASL isactivated.

AWHITE symbol: The function is active. GRAY symbol: Standbymode.BSee "ASL symbol" below for an explanation of the symbol's dif-ferent colors.

ASL symbol
The road sign symbol (next to thestored speed ("70" here) in the centerof the speedometer) can be displayedin three different colors, which areexplained in the following table:

Activating/deactivating AutomaticSpeed Limiter
The Automatic Speed Limiter (ASL) is a supple-ment to the Speed Limiter (SL) and can be acti-vated/deactivated.

Activating ASL
The Speed Sign Assist but-ton is located in the center dis-play's Function view.
To activate the Automatic Speed Limiter:
1.Tap the Speed Sign Assist button.
> ASL will go into standby mode and agreen indicator light will illuminate. A roadsign symbol will be displayed in the centerof the speedometer in the instrumentpanel.
2.Pressing the button on the steeringwheel keypad.
> ASL will be activated and set to the vehi-cle's current speed.
NOTE
If the Automatic Speed Limiter function isactivated, road sign information is shown
in the driver display even if RSI15 is notactivated.
To remove road sign information from thedriver display, you must deactivate bothAutomatic Speed Limiter and RSI.
When the Automatic Speed Limiter func-tion is activated but RSI is deactivated, nowarnings are given from RSI. RSI mustalso be activated for warnings to be pos-sible.

Deactivating ASL
To deactivate the Automatic Speed Limiter:
–Tap the Speed Sign Assist button in Func-tion view.
> ASL will be deactivated, the indicator lightin the button will be GRAY and SL will beactivated instead.

WARNING
The vehicle will no longer follow the postedmaximum speed after switching from ASL toSL – it then only follows the maximum speedstored in the memory.

Changing Automatic Speed Limitertolerance
The Automatic Speed Limiter (ASL) can be setto different tolerance levels.
It is also possible to allow the vehicle to driveabove or below the posted speed limit. For exam-ple, if the vehicle is following a current postedspeed limit of 70 km/h (43 mph), the driver caninstead allow the vehicle to maintain a speed of75 km/h (47 mph).
Function buttons and symbols16.
–Tap the (1) button on the steeringwheel keypad until 70 km/h (43 mph) hasbeen changed to 75 km/h (47 mph) in thecenter of the speedometer (4).
> The vehicle will then use the selected tol-erance of 5 km/h (4 mph) as long as theposted speed limit the vehicle passes is70 km/h (43 mph).
This tolerance level will be followed untilthe vehicle passes a sign with a lower orhigher speed. The vehicle will then adjustto the new speed limit and the set toler-ance will be deleted from the system'smemory.
If Road Sign Information*17 is activated,the posted speed limit will also be indi-cated by a RED marking on the speedom-eter.
The set tolerance can be adjusted in the sameway as for the Speed Limiter's speed.

NOTE
The highest possible selectable tolerance is+/- 10 km/h (5 mph).

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.

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-

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.
