Driving and parking<br />
If you want DISTRONIC PLUS to assist you,<br />
the radar sensor system must be activated<br />
(Y page 232) and operational.<br />
If there is no vehicle in front, DISTRONIC<br />
PLUS operates in the same way as cruise<br />
control in the speed range between<br />
20 mph (Canada: 30 km/h) and<br />
120 mph (Canada: 200 km/h). If there is a<br />
vehicle in front, DISTRONIC PLUS is<br />
operational in the speed range between<br />
0 mph (Canada: 0 km/h) and<br />
120 mph (Canada: 200 km/h).<br />
Do not use DISTRONIC PLUS while driving on<br />
roads with steep gradients.<br />
As DISTRONIC PLUS emits radar waves, it can<br />
simulate radar detectors used by police<br />
authorities. You can refer to the applicable<br />
section in the Operator's Manual if there are<br />
any questions concerning this.<br />
i USA only:<br />
This device has been approved by the FCC<br />
as a “Vehicular Radar System”. The radar<br />
sensor is intended for use in an automotive<br />
radar system only. Removing, tampering<br />
with, or altering the device will void any<br />
warranties, and is not permitted by the<br />
FCC. Do not tamper with, alter, or use in<br />
any non-approved way.<br />
Any unauthorized modification to this<br />
device could void the user’s authority to<br />
operate the equipment.<br />
G Warning!<br />
The DISTRONIC PLUS adaptive cruise control<br />
is not a substitute for active driving<br />
involvement. It does not react to pedestrians<br />
or on stationary objects, nor does it recognize<br />
or predict the curvature and lane layout or the<br />
movement of preceding vehicles. The<br />
DISTRONIC PLUS can only apply a maximum<br />
of 40% of the vehicle's braking power.<br />
The DISTRONIC PLUS may not detect narrow<br />
vehicles possibly driving in front of you, such<br />
as motorcycles and vehicles driving in an<br />
offset formation.<br />
It is the driver's responsibility at all times to<br />
be attentive to the road, weather and traffic<br />
conditions. Additionally, the driver must<br />
provide the steering, braking and other driving<br />
inputs necessary to remain in control of the<br />
vehicle.<br />
High-frequency sources such as toll stations,<br />
speed measuring systems etc. can cause the<br />
DISTRONIC PLUS system to temporarily<br />
cease functioning.<br />
G Warning!<br />
The DISTRONIC PLUS cannot take road and<br />
traffic conditions into account. Only use the<br />
DISTRONIC PLUS if the road, weather and<br />
traffic conditions make it advisable to travel<br />
at a constant speed.<br />
G Warning!<br />
Use of the DISTRONIC PLUS can be<br />
dangerous on slippery roads. Rapid changes<br />
in tire traction can result in wheel spin and<br />
loss of control.<br />
The DISTRONIC PLUS does not function in<br />
adverse sight and distance conditions. Do not<br />
use the DISTRONIC PLUS during conditions of<br />
fog, heavy rain, snow or sleet.<br />
G Warning!<br />
The DISTRONIC PLUS cannot take weather<br />
conditions into account. Switch off the<br />
DISTRONIC PLUS or do not switch it on if:<br />
Rroads are slippery or covered with snow or<br />
ice. The wheels could lose traction while<br />
braking or accelerating, and the vehicle<br />
could skid.<br />
Rthe DISTRONIC PLUS system sensor covers<br />
are dirty or visibility is diminished due to<br />
snow, rain or fog, for example. The distance<br />
control system functionality could be<br />
impaired.<br />
Always pay attention to surrounding traffic<br />
conditions even while the DISTRONIC PLUS is<br />
switched on. Otherwise, you may not be able<br />
to recognize dangerous situations until it is
