& WARNING (continued)
• Please note that inadvertently "resting" your foot on the accel­
erator pedal causes the cruise control not to brake . This is because
the cruise control is overridden by the driver's acceleration.
[ i J Tips
The brake lights illuminate as soon as the brakes decelerate
automatically. •
Changing speed
-Press lever in the 0 or O direction => page 137, fig. 149
to increase or decrease your speed.
- Release the lever to save that speed.
Change speed in increments of 1 mph (1 km/h) by lightly pressing
the lever . If you keep the lever pressed down, you will alter your
speed in 5 mph (10 km/h) increments.
You can also press the accelerator pedal down to increase your
speed, e.g . if you want to pass someone. The speed you saved
earlier will resume as soon as you release the accelerator pedal.
If, however, you exceed your saved speed by 5 mph (10 km/h) for
longer than 5 minutes, the cruise control will turn off temporarily.
The green symbol in the display=>
page 137, fig. 150 is rep laced
with a white symbol. The saved speed remains the same. •

& WARNING
Following other vehicles too closely increases the risk of a crash
and serious personal injury .
• Following other vehicles too closely, particularly at higher
speeds increases the risk of collisions and serious personal injury .
• Setting short distances to the traffic ahead reduces the time
and distance available to bring your vehicle to a safe stop and
makes it even more necessary to pay close attention to traffic.
• Always select a speed and distance to traffic ahead that is safe
and appropriate under the prevailing traffic, road, weather and
lighting conditions.
• Never rely on the distance control feature of ACC alone to
prevent rear-end collisions. Always be prepared to brake and take
evasive action to avoid collisions and other accident situations.
• Never allow the closing speed between you and other vehicles
to be so high that the Adaptive Cruise Control may not be able to slow your vehicle safely .
If closing speed is too high, you must
apply the brakes yourself to reduce the risk of a rear-end crash.
• Always select a greater following distance to the vehicle ahead
on wet roads than on dry roads.
• Always read and heed the information and

[ i J Tips
• If the Adaptive Cruise Control initiates braking, the hydraulic
brake system is under pressure . Therefore, the brake peda l distance
is shorter and the pedal feels "harder".

For the time being, the distance to vehicles up ahead is not being
controlled. The ACC system is not switched off, so increased a lert­
ness is required. The following may be reasons for the text message
ACC sensor blocked:
• The ACC sensor is d irty. The ACC system is not reacting, or is not
reacting correctly, to vehicles trave ling ahead .
• It is possible that you are dr iving on a road with very light traffic
without anything at the side of the road (e.g. guard rai ls, traffic
s igns, trees) . As soon as a vehicle is detected by the system aga in,
it returns to its control range and the text message disappears .
