Speed limiter (p. 283) Cruise Control limitations
On steep downgrades, the Speed limiter's brak-
ing capacity may not be sufficient and the set
maximum 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 least
3 km/h (ca 2 mph).

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

WARNING

The ASL function is supplementary driver
support intended to facilitate driving and
help make it safer – it cannot handle all
situations in all traffic, weather and road
conditions.
Even if the driver can clearly see the
speed limit sign, the speed information
from the Road Sign Information (RSI)
function to ASL may be incorrect. In such
cases, the driver must intervene and
accelerate or brake to an appropriate
speed.
ASL is not a substitute for the driver's
attention and judgment. The driver is
always responsible for ensuring the vehi-
cle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

mation limitations".Is SL or ASL active?The symbols in the instrument panel indicate

Activating/deactivating Automatic
Speed Limiter
The Automatic Speed Limiter (ASL) is a supple-
ment to the Speed Limiter (SL) and can be acti-
vated/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 center
of the speedometer in the instrument
panel.
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 shown
in the driver display even if RSI 19
is not
activated.
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, no
warnings are given from RSI. RSI must
also be activated for warnings to be pos-
sible.
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 to
SL – it then only follows the maximum speed
stored in the memory.

tolerance
The Automatic Speed Limiter (ASL) 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 posted
speed limit of 70 km/h (43 mph), the driver can
instead allow the vehicle to maintain a speed of
75 km/h (47 mph).

. –
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 the
center 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 is
70 km/h (43 mph).
This tolerance level will be followed until
the vehicle passes a sign with a lower or
higher speed. The vehicle will then adjust
to the new speed limit and the set toler-
ance will be deleted from the system's
memory.
If Road Sign Information* 21
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 same
way 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 RSI 22
function, not from the speed limit signs that the
vehicle passes.
If RSI 22
is unable to interpret and provide ASL
with speed information, ASL will go into standby
mode and switch over to SL. The driver will then
have to actively brake to bring the vehicle down
to the appropriate speed.
ASL will be reactivated when RSI 22
is once again
able to interpret and provide speed information to
ASL.
See “Road Sign Information limitations” for more
information.

WARNING

The cruise control function is supplemen-
tary driver support intended to facilitate
driving and help make it safer – it cannot
handle all situations in all traffic, weather
and road conditions.
The driver is advised to read all sections
in the Owner's Manual about this function
to learn of its limitations, which the driver
must be aware of before using the func-
tion (see the link list at the end of this
article).
Cruise control is not a substitute for the
driver's attention and judgment. The driver
is always responsible for ensuring the
vehicle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

Cruise Control (CC 25
) can be set to various
speeds.
Setting/changing set speed Note: This illustration is general and details may vary
depending on model and market.
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 to
the 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 to
the set speed when the accelerator pedal is
released. 24

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 to
the 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 to
the set speed when the accelerator pedal is
released.
Using engine braking instead of
applying the brakes
Cruise Control regulates speed by lightly applying
the brakes. On downgrades, it can sometimes be
desirable to roll a bit faster and let speed be
reduced instead by engine braking alone. The
driver 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 the
engine braking function.
How drive mode affects cruise controlThe way the cruise control maintains the vehicle's
speed can vary depending on the selected drive
mode 26
.
Cruise Control Eco Cruise with ECO drive
mode
In the ECO drive mode, cruise control's accelera-
tion and deceleration will be smoother than in
other drive modes to help provide optimal fuel
efficiency and reduced environmental impact.
Because of this, the vehicle's actual speed may
be 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 and
more immediate than in other drive modes.
