When Driving
i-ACTIVSENSE
The CTS may not be able to detect a
vehicle ahead depending on the type
of vehicle ahead and its conditions,
the weather conditions, and the road
conditions. Additionally, the system
might be unable to decelerate
sufficiently if a vehicle ahead applies
the brakes suddenly, another vehicle
cuts into the driving lane, or the
difference in vehicle speed between
your vehicle and the vehicle ahead is
larger, which could result in an
accident. Check the surrounding
conditions and always drive carefully
while keeping a safe distance from
vehicles ahead and on-coming
vehicles.
For the purposes of safety, switch the
CTS off when it is not being used.
Leaving the CTS turned on when it is
not in use is dangerous as it could
operate unexpectedly, resulting in an
accident.
Do not use the CTS under the
following conditions. Otherwise, it
may result in an accident.
General roads other than
expressways or highways (Driving
under these conditions using the CTS
is not possible.)
Roads with sharp curves and where
vehicle traffic is heavy with
insufficient space between vehicles,
or roads where frequent and
repetitive acceleration and
deceleration occur (Driving under
these conditions using the CTS is not
possible).
4-148
When entering and exiting
interchanges, service areas, and
parking areas of expressways (If you
exit an expressway while headway
control is in use, the vehicle ahead
will no longer be tracked and your
vehicle may accelerate to the set
speed).
Slippery roads such as icy or
snow-covered roads (Tyres could
spin causing you to lose vehicle
control, or the stop hold control may
not operate.)
Long, descending slopes (to
maintain distance between vehicles,
the system automatically and
continuously applies the brakes
which could result in the loss of
brake power.)
Two-wheeled vehicles such as
motorcycles or bicycles are ahead.
(Automatic transmission vehicle)
Slopes with a steep gradient (The
vehicle ahead may not be detected
correctly, your vehicle may slip while
stopped by the stop hold control, or
it may accelerate suddenly after it
starts moving.)
Driving under bad weather
conditions (rain, fog, and snow).
The vehicle is driven on slippery
roads such as icy or snow -covered
roads and unpaved roads (Tyres
could spin causing you to lose
vehicle control, or the stop hold
control may not operate.)
Tyres of a different specified size are
used, such as a temporary spare tyre.
Tyres with insufficient tread are used.
The tyre pressures are not adjusted to
the specified pressure.
The vehicle is being used to tow a
camper or boat trailer.
Tyre chains are used.
