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 in
the instrument panel to alert the driver.
NOTE
A text message on exceeded max. speed is activated if the speed is exceeded by at least3 km/h (ca 2 mph).

Automatic Speed Limiter
The Automatic Speed Limiter (ASL 18
) function
helps the driver adapt the vehicle's maximum speed to the posted speed limits.
The Speed Limiter (SL 19
) function can be
switched to Automatic Speed Limiter (ASL). The Automatic Speed Limiter function uses speed information from the Road Sign Informa- tion function 20
to automatically adapt the vehi-
cle's maximum speed.

WARNING
•The ASL function is supplementary driver support 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".

Activating/deactivating AutomaticSpeed Limiter
The Automatic Speed Limiter (ASL 21
) is a sup-
plement to the Speed Limiter (SL 22
) and can be
activated/deactivated.
Activating ASLThe 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 a green indicator light will illuminate. A road sign symbol will be displayed in the centerof the speedometer in the instrumentpanel.
2. Pressing the
button on the steering
wheel keypad.
> ASL will be activated and set to the vehi- cle's current speed.
NOTE
• If the Automatic Speed Limiter function is activated, road sign information is shownin the driver display even if RSI is notactivated.
• To remove road sign information from the driver display, you must deactivate
both
Automatic Speed Limiter and RSI.
• When the Automatic Speed Limiter func- tion is activated but RSI is deactivated, nowarnings are given from RSI. In this situa-tion, settings for RSI cannot be adjustedeither - to be able to adjust settings aswell as receive warnings, RSI must beactivated.
Deactivating ASLTo deactivate the Automatic Speed Limiter:
–Tap the Speed Sign Assist button in Func-
tion view.
> ASL will be deactivated, the indicator light in the button will be GRAY and SL will be activated instead.
WARNING
The vehicle will no longer follow the posted maximum 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 23
) can be set
to different tolerance levels.
It is also possible to allow the vehicle to drive above 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 symbols 24
.
–Tap the (1) button on the steering
wheel keypad until 70 km/h (43 mph) has been 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 the posted speed limit the vehicle passes is70 km/h (43 mph). This tolerance level will be followed until the 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 * is activated, the
posted speed limit will then be indicated by a RED marking on the speedometer'sspeed scale.
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
ASL utilizes the speed limit information provided by the RSI 25
system, not from the speed limit
signs that the vehicle passes.
If RSI 25
is unable to interpret and provide ASL
with speed information, ASL will go into standby mode 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 RSI 25
is once again
able to interpret and provide speed information to ASL. See "Road Sign Information limitations" for more information.

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
