■When the vehicle has been parked in the sun
The LDA system may not be available for a while after driving has started. In such
cases, turn the LDA system off and turn it on again after normal temperature
returns. When the temperature in the cab in decreases and the temperature around
the camera sensor becomes suitable for it s operation, the functions will begin to
operate.
■Warning lights and messages for LDA
Warning lights and messages are used to in dicate a system malfunction or to inform
the driver of the need for caution while driving. ( P. 705)
CAUTION
■Before using the LDA system
This system provides information to the driver in accordance with the road geome-
try and the driving conditions. Be aware of your surroundings at all times, correct
the driving path while driving appropriately and be responsible for your own safety.
This system operates by using the camera to identify lane markers when the LDA
switch is on and the vehicle is being driven at the system operating speed.
Operation may be temporarily suspended if the camera cannot recognize the lane
markers or if the system cannot operate due to the road environment or driving
conditions. Also, since an alarm may sound unnecessarily if the lane markers cannot
be correctly identified, make sure to drive responsibly even while the system is
operating.
If a malfunction occurs in the system, the driver will be alerted by a buzzer and a dis-
play, and LDA operation will be temporarily suspended. However, this does not
present a problem to normal driving.
If the alert is displayed even after restarti ng the engine, have your vehicle inspected
by your Lexus dealer.

GX460_OM_OM60J63U_(U)
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-visibil-
ity conditions. It is still necessary for the driver to pay close attention to the vehi-
cle’s surroundings.
●Assisting the driver in making correct judgment
When attempting to estimate the possibilit y of a collision, the only data available
to the pre-collision system is that from ob stacles 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 possibility of collision in any given situ-
ation.
●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 col-
lision or bringing the vehicle to a stop safety. 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.
