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.

experience on highways and long, straight roads
with even traffic flows.

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

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 most recently set speed will be stored.
If speed is increased by depressing the accelera-
tor pedal while pressing the (1) button on

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.

The Distance Alert 31
function can help the driver
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. 29

When the vehicle is approaching an off-ramp
or a fork in the road, the driver should steer
toward the desired lane to indicate to Pilot
Assist the desired direction of travel.
Pilot Assist strives to keep the vehicle
in the center of the lane
When Pilot Assist provides steering assistance, it
strives to position the vehicle in the center of the
lane between the lane markings. For the smooth-
est driving experience possible, the driver should
permit the vehicle to find the optimal positioning.
The driver should check that the vehicle is posi-
tioned safely in the lane and can always adjust
the vehicle's position by applying more force to
the steering wheel.
If Pilot Assist does not position the vehicle
appropriately in the lane, the driver should
turn off Pilot Assist or switch to Adaptive
Cruise Control.

Automatic transmission
Pilot Assist can follow another vehicle at speeds
from a standstill up to 200 km/h (125 mph).
The lowest speed that can be set for Pilot Assist
is 30 km/h (20 mph). When following another
vehicle, ACC can monitor that vehicle's speed
and slow your own vehicle down to a standstill,
but it is not possible to set speeds lower than
30 km/h (20 mph). The highest possible speed that can be set is
200 km/h (125 mph).
