Adaptive cruise control
Speed and distance control system
Applies to veh icles: wit h adaptive cruise contro l
Description
The adaptive cruise control driver assistan ce program is a
combined speed and distance control system .
Fig. 106 Front
bum per: Position of
radar sensor
Any speed betwee n about 20 mph (30 km/h) and about 95 mph
(150 km/ h) can be set and held with the adaptive cruise control. The
system also regu lates a pre-set distance from the vehicle ahead
with in the limits of the system described.
Driving can be more relaxed, particularly o n long tr ips on inter states
or on other highways that are generally straig ht .
How does it work?
You ca n operate the adaptive cruise contro l using the leve r o n the
steer ing wheel column :::,
page 117, "How is the speed sto red? " and
=:> pag e 119 , "How is the distance (time interval) set?".
Driver information
Important info rmation is brought up in the speedometer and in the
instrumen t clust er display as the vehicle is be ing dr iven :::,
page 120,
"Driver informat ion".
What is important for you to know
The adaptive cruise cont rol is set with system-specified limits, that is,
as a driver, you will have t o adju st the speed and dist an ce t o the
vehicle ahead in some instances :::,
page 124 , "Driver inte rvention
promp t " and =>
page 125, "System limit at ions ".
& WARNING
Improper use of the adaptive cruise control can cause colli sions,
othe r accidents and serious personal injury.
• Never drive at speeds that are too high for traffic, road and
weather condition s .
• Never follow the vehicle in front so closely that you cannot stop
your vehicle safel y. The adaptive cruise control cannot brake the
vehicle safely when you follow another vehicle too closely . Always
remember that the adapti ve cruise control has a braking power
that is only about 25% of the vehicle 's maximum braking ability,
the automatic braking function cannot bring the vehicle to a stop.
• Never use adaptive cruise control on roads where you cannot
drive s afely at a steady speed , including city, stop-and-go or heavy
traffi c, on winding roads or when road cond ition s are poor (for
example , on ice, gravel, in fog, heavy rain or on wet roads that
increase the risk of hydroplaning).
• The radar sensor' s
vision can be reduced by rain, snow and
heavy spray . This can result in vehicle s driving ahead being inade-
quately detected or, in some circumstances , not detected at all. If
necessary, t ake action yourself! ..,
