Changing Automatic Speed Limiter
tolerance
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 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). Function buttons and symbols

. –
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* is activated, the
posted speed limit will then be indicated
by a RED marking on the speedometer's
speed scale.
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).

Speed limiter (p. 278) 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 then
have to actively brake to bring the vehicle down
to 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.

288Managing Cruise Control speed
Cruise 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 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.
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 30

Cruise Control Eco Cruise
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.

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.
Automatic standby mode
Cruise Control will be temporarily deactivated and
put in standby mode if:
• the wheels lose traction
• the engine speed (rpm) is too low/high
• the temperature in the brake system
becomes too high
• the vehicle's speed goes below 30 km/h
(20 mph).
The driver must then control the vehicle's speed.

become aware if the time interval to the vehicle
in front is too short.
However, the vehicle must be equipped with a
head-up display in order to display the Distance
Alert, which will then be indicated by a symbol
on the windshield as long as the time interval to
the vehicle ahead is shorter than the set time
interval.
Distance Alert is active at speeds above 30 km/h
(20 mph) and only reacts for vehicles ahead mov-
ing in the same direction as your vehicle. No dis-
tance information is provided for oncoming, slow-
moving or stationary vehicles. 33
