ENG A-STOP system
(engine auto stop start
system) (if equipped)
The ENG A-STOP system (engine auto
stop start system) automatically stops and
restarts the engine without operating the
ignition switch or the engine switch when
the vehicle is stopped, such as at a traffic
signal or in a traffic jam, to reduce exhaust
gases and fuel consumption.
• When the vehicle will be stopped for a
long time or when you will leave the
vehicle unattended, turn the ignition
switch to “LOCK” position or press the
engine switch to stop the engine.
NOTE:
If your vehicle is equipped with the auto air
conditioning system, you can change the
auto engine stop condition via the informa-
tion display. Refer to “Information display”
in “BEFORE DRIVING” section.

Radar brake support system
(if equipped)
Radar brake support system measures the
relative velocity of, and distance from, the
vehicle in front of you by radar and then
attempts to avoid a crash by giving warn-
ing and, in the event of a crash, attempts to
reduce damage through brake control.
WA R N I N G
• Radar brake support system has
limits and may not function prop-
erly depending on the driving con-
ditions. Do not rely excessively on
the system and always drive in a
safe manner.
• For safety reasons, do not check
the operation of the system by
yourself.
• Check that all passengers fasten
their seat belts when the vehicle is
being operated.

for further assistance.NOTE:
In the following situations, the radar brake
support system warning light (3) may come
on, the message (4) may appear and the
radar brake support system may be deacti-
vated automatically, even if there is no dirt
on the sensor cover.
• In a tunnel
• A road where there are concrete walls
on both sides
• A road where there are metal fences on
one side
• Around overpasses or grade separated
crossings
• When there is bad weather such as
heavy rain or snow
• A road where there are puddles
In these situations, the radar brake support
system is stop functioning temporarily,
because millimeter-waves emanating from
the radar sensor cause diffused reflection
and a position of the vehicle in front of you
cannot be detected correctly.
If you drive the vehicle for about 2 minutes
after the above situations have improved,
these indicator and message will turn off
and the radar brake support system will
turn back on.
