vehicle



Fig. 126 Example: driving into a curve
In some situations, the adaptive cruise assist
function is limited and you must assume control
of the vehicle when necessary, for example by ap-
plying the brakes.
— Ifa vehicle that was already detected @ turns
or changes lanes, the adaptive cruise assist will
react to the vehicle ahead of it @).
— When driving into a curve > fig. 126 and out of
a curve, the adaptive cruise assist may react to
a vehicle in the adjacent lane and apply the
brakes. You can override the system by pressing
the accelerator pedal briefly.
— The adaptive cruise assist works with the vari-
ous sensors and cameras in the vehicle.
Vehicles can only be detected once they are
within the area and range covered by the sen-
sors > page 155, fig. 115.
— When driving around tight curves, a vehicle
driving ahead that was previously detected may
no longer be detected, and the adaptive cruise
assist may accelerate unexpectedly.
— The adaptive cruise assist does not react toa
stationary vehicle in the same lane if the sys-
tem expects that you can easily drive around
the stationary vehicle by turning the steering
wheel.
— The adaptive cruise assist may not react to sta-
tionary obstacles, such as the end of a traffic
jam, especially at high speeds.
— The adaptive cruise assist has a limited ability
to detect vehicles that are a short distance
ahead, off to the side of your vehicle, or moving
into your lane.
— Objects that are difficult to detect, such as mo-
torcycles, vehicles with high ground clearance,
or vehicles with an overhanging load, may be
detected late or not detected at all.

cle was detected ahead. The adaptive cruise as-
sist controls the speed and distance from the ve-
hicle driving ahead, and accelerates and brakes
automatically.
A - The speed/distance control is active but the
vehicle is not ready to drive. A vehicle was de-
tected ahead. Your vehicle is stationary and will
not start driving automatically.
BS - The speed/distance control is active but the

Driver assistance


ZA WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 154.
— The activated adaptive cruise assist is only
an assist system, and the driver is still re-
sponsible for controlling the vehicle. The
driver is especially responsible for braking,
steering, starting to drive, and controlling
the speed and the distance from other
vehicles.
— Turn on the adaptive cruise assist only if the
surrounding conditions permit it. Always
adapt your driving style to the current visu-
al, weather, road, and traffic conditions.
— Switch the adaptive cruise assist off tempo-
rarily when driving in turning lanes or high-
way exits. This prevents the vehicle from ac-
celerating to the stored speed when in these
situations.
— If you press the [SET|) button when driving
at speeds below 20 mph (30 km/h), then 20
mph (30 km/h) will be set because that is
the minimum speed that can be set. If no
vehicle is detected ahead of you, the vehicle
will accelerate up to that speed.


G) Tips
— Always keep your hands on the steering
wheel. The driver is always responsible for
adhering to the regulations applicable in
the country where the vehicle is being oper-
ated.
— If you switch the ignition or the adaptive
cruise assist off, the stored speed is erased
for safety reasons.
— When the adaptive cruise assist is switched
on, the ESC and the ASR are switched on au-
tomatically.
— The system cannot be switched off if the
road exceeds the maximum possible grade
for safe operation.

cator light informs you if lane guidance is availa-
ble G0 > page 172, fig. 128.
If the Hi or WM indicator light turns on white on
at least one side, or the & indicator light turns
on white in the Driver assistance display, then
lane guidance is not active. This may be due to
the following reasons:
— The necessary lane marker lines have not been
detected (for example, in a construction zone
or because the lines are obstructed by snow,
dirt, water, or lighting)
— The lane is too narrow or too wide
— The curve is too narrow
— Visibility is obstructed by a rise or dip.

Lane departure warning
(erreur laced)
Applies to: vehicles with lane departure warning
The lane departure warning can detect lane
marker lines within the limits of the system. If
you are approaching a detected lane marker and
it appears likely that you will leave the lane, the
system can warn you with corrective steering and
a steering wheel vibration, if necessary.
The system functions in the speed range of ap-
proximately 40 mph - 155 mph (65 km/h -
250 km/h).
Applies to: vehicles with lane departure warning
and without side assist: The system will not warn
you before crossing a lane marker line if you have
activated the turn signal. In this case, it assumes
that you are changing lanes intentionally.
Applies to: vehicles with lane departure warning
combined with side assist: A noticeable corrective
steering movement will occur briefly before the
vehicle exits the lane if the turn signal is activat-
ed, the lane departure warning is ready, anda
lane change has been classified as critical by the
system due to vehicles traveling beside you or
due to approaching vehicles. This will attempt to
keep your vehicle in the lane.
