CAUTION
■Turn the LKA off while driving in any of the following conditions
Do not use LKA in any of the following situations.
Otherwise, the system may not function correctly and could result in an acci-
dent.
● When driving with snow tires, snow chains, a spare tire, or similar equip-
ment.
● When driving with non-standard parts or aftermarket equipment installed.
(including modified tires and suspensions, etc.)
● When there are objects or structures along the roadside that might be mis-
interpreted as lane markers. (such as guardrails, curb, reflector posts, etc.)
● When there are wheel ruts, icy trademar ks, etc. or if snow remains on the
road surface.
● When there are shadows on the road r unning parallel with lane markers,
or if a shadow covers the lane markers.
● When there are visible lines on the pavement from road repairs, or if the
remains of old lane markers are still visible on the road.
● When driving on slippery roads, such as those covered with rain, ice or
snow.
● When driving in a lane other than the driving or passing lanes on a freeway
or highway.
● When driving on a road with lane closures due to maintenance, or when
driving in a temporary lane.

Hill-start assist control
■Hill-start assist control can be operated when
●The shift position is in a position other than P.
● The parking brake is not applied.
● The accelerator pedal is not depressed.
■ Hill-start assist control
●While hill-start assist control is operating, the brakes remain automati-
cally applied after the driver releases the brake pedal. The stop lights and
the high mounted stoplight turn on.
● Hill-start assist control operates for about 2 seconds after the brake pedal
is released.
● If the slip indicator does not flash and the buzzer does not sound when
the brake pedal is further depressed, slightly reduce the pressure on the
brake pedal (do not allow the vehicl e to roll backward) and then firmly
depress it again. If the system still does not operate, check if the operat-
ing conditions explained above have been met.
Hill-start assist control helps to prevent the vehicle from rolling
backwards when starting on an incline or slippery slope.
To engage hill-start assist con-
trol, further depress the brake
pedal when the vehicle is
stopped completely.
A buzzer will sound once to
indicate the system is acti-
vated. The slip indicator will
also start flashing.

CAUTION
■Limitations of the pre-collision system
Do not overly rely on the pre-collision system. Always drive safely, taking
care to observe your surroundings and checking for any obstacles or other
road hazards.
Failure to do so may cause an accident resulting in death or serious injury.
■ Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-collision system is intended
to assist the driver in avoiding collisions through the process of LOOK-
JUDGE-ACT. There are limits to the degree of assistance the system can
provide, so please keep in mind the following important points.
●Assisting the driver in watching the road
The pre-collision system is only able to detect obstacles directly in front of
the vehicle, and only within a limited range. It is not a mechanism that
allows careless or inattentive driving, and it is not a system that can assist
the driver in low-visibility conditions. It is still necessary for the driver to
pay close attention to the vehicle’s surroundings.
● Assisting the driver in making correct judgement
When attempting to estimate the possibility of a collision, the only data
available to the pre-collision system is that from obstacles it has detected
directly in front of the vehicle. Therefore, it is absolutely necessary \
for the
driver to remain vigilant and to determine whether or not there is a possi-
bility of collision in any given situation.
● Assisting the driver in taking action
The pre-collision system’s braking assist feature is designed to help
reduce the severity of a collision, and so only acts when the system has
judged that a collision is unavoidable. This system by itself is not capable
of automatically avoiding a collision or bringing the vehicle to a stop safely.
For this reason, when encountering a dangerous situation the driver must
take direct and immediate action in order to ensure the safety of all
involved.

340 3-1. Using the air conditioning system and defogger
■Operating conditions
The Solar Ventilation System may not operate under the following circum-
stances due to a lack of power from the solar panel:
●Low amount of sunlight
● Ever when a part of the solar panel is cast by a shadow.
● Ever when a part of the solar panel is covered by fallen leaves or dirt.
● The solar panel is not at a high temperature.
■ Before using the Solar Ventilation System
Remove dirt or fallen leaves from the solar panel in order to ensure sufficient
electrical output.
■ Efficient use of the So lar Ventilation System
Efficient control of temperature increase can be achieved by using the sys-
tem in conjunction with the Remote Air Conditioning System. ( P. 342)
■ When using the Sola r Ventilation System
● Make sure that the “POWER” switch is in ON mode when turning the
ventilation switch on. If the ventilation switch is turned on while the
“POWER” switch is OFF, the air mode and the status of the air vents will
remain unchanged.
● If the Solar Ventilation System is not needed, be sure to turn the ventila-
tion switch off.
Dirty air and exhaust fumes from other vehicles may be drawn from out-
side. Also, use in winter may cause heated interior air to leave the vehi-
cle, thus leading to a drop in temperature.
■ Sounds when using the Solar Ventilation System
If the amount of sunlight is insufficient, you may hear a sound coming from
the air conditioning system. This is the sound of a control function to pre-
serve the fan and does not indicate a malfunction.
