GX 460 _O M_ OM6 0F 6 8U _(U )4-5. Using the driving support systems
CAUTION
■Limitations of the pre-collision system
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
Do not use the pre-collision system instead of normal braking operations under any
circumstances. This system will not prevent collisions or lessen damage or injuries in all
cases. Do not overly rely on this system. Failure to do so may cause an accident, result-
ing in death or serious injury.
This system has been designed to help avoid and reduce the impact of collisions. How-
ever, the system operates differently depending on the situation (
→P. 371, 372). As a
result, the same level of performance may not be expected in all cases. Also, the pre-
collision brakes may not operate if the driver is depressing the brake pedal or turning
the steering wheel, as the system will determine such conditions as collision avoidance
operations.
■Cautions regarding the assist contents of the system
By means of alarms and brake control, the pr e-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 inatten-
tive driving, and it is not a system that can as sist 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 judgment
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 possibility 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 sever-
ity of a collision, and so on ly acts when the system has judged that a collision is
unavoidable. This system is not capable of automatically avoiding a collision or bring-
ing the vehicle to a stop safely without appropriate operations performed by the
driver. 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.

GX 460 _O M_ OM6 0F 6 8U _(U )6-3. Do-it-yourself maintenance
■Brake fluid can absorb moisture from the air
Excess moisture in the fluid can cause a dang
erous loss of braking efficiency. Use only
newly opened brake fluid.
CAUTION
■When filling the reservoir
Take care because brake fluid can harm your hands or eyes and damage painted sur-
faces. If fluid gets on your eyes, flush the affected area with clean water immediately. If
you still experience discomfort, see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or when
the fluid level in the accumulator is high. If the reservoir needs frequent refilling, it may
indicate a serious problem.

When trouble arises
CAUTION
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Lexus dealer. The vehi-
cle will become extremely unstable during br aking, and the ABS system may fail, which
could cause an accident resulting in death or serious injury.
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause loss of vehi-
cle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pressure
immediately.
●If the tire pressure warning light comes on even after tire inflation pressure adjust-
ment, it is probable that you have a flat tire. Check the tires. If the tire is flat, change to
the spare tire and have the flat tire repaired by the nearest Lexus dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could lose
control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
