CAUTION
■Situations unsuitable for dynamic laser cruise control
Do not use dynamic laser cruise control in any of the following situations.
Doing so may result in inappropriate control of speed and could cause seri-
ous or fatal accident.
●In heavy traffic
● On roads with sharp bends
● On winding roads
● On slippery roads, such as those covered with rain, ice or snow
● On steep downhills, or where there are sudden changes between sharp up
and down gradients
● At entrances to expressways
● When weather conditions are bad enough that they may prevent the sen-
sors from functioning correctly (fog, rain, snow, sandstorm, direct sunlight,
etc.)
● Where buzzer can be heard often
● When your vehicle is towing anything
■ When the laser radar sensor may not be correctly detecting the vehicle
ahead
Apply the brakes as necessary when any of the following types of vehicles
are in front of you.
As the sensor may not be able to correctly detect these types of vehicles,
the proximity alarm ( P. 592) will not be activated, and an accident may
result.
● The vehicle ahead has higher ground clearance, which means that the
placement of the reflectors is in a higher position.
● The rear section of the vehicle ahead is extremely dirty.
● The vehicle ahead or other vehicles around you are flinging up water or
snow.
● Excessive exhaust gas (black smoke) is coming from the vehicle ahead or
other vehicles around you, obscuring your front view.

■Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect
the ability of a sensor to correctly detect an obstacle. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on a sensor.
• A sensor is frozen.
• A sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises producing
ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected. Objects lower than the sensors or thin stakes etc. may be detected ini-
tially, but as they draw closer, they may cease to be detected.
• A towing hitch is mounted to the vehicle.
• A non-genuine Toyota suspension (lowered suspension etc.) is installed.
• When attaching a two-way radio antenna.
• When a towing eyelet is mounted on your vehicle.
• When the bumper is damaged.
In addition to the examples above, there are instances in which, because of
their shapes, signs and other objects may be judged by a sensor to be closer
than they are.
● The shape of the obstacle may prevent a sensor from detecting it. Pay
particular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles

When driving
To disable A-TRAC (4L mode on 4WD models)
If the vehicle gets stuck in fresh snow or mud, A-TRAC may reduce
power from the engine to the wheels. You may need to turn the sys-
tem off to enable you to rock the vehicle in order to free it. Stop the vehicle completely, and
press the VSC OFF switch for
more than 3 seconds.
The slip indicator will come on.
The system is in all off mode.
Push the switch again to turn the
system back on.
■Automatic A-TRAC reactivat ion (A-TRAC OFF mode)
With A-TRAC OFF mode, slip indicator turn on. The A-TRAC system will turn
on when the vehicle speed increases.
■ Sounds and vibrations caused by the ABS, TRAC, A-TRAC, VSC and
brake assist system
●A sound may be heard from the engine compartment when the engine is
started and just after the vehicle begins to move. This sound does not
indicate that a malfunction has occurred in any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ If the brake system overheats
TRAC or A-TRAC will cease operation, and the slip indicator will change
from flashing to being on continuously to alert the driver. Stop the vehicle in
a safe place. (There is no problem with continuing normal driving.)

512 4-3. Do-it-yourself maintenance
NOTICE
■If you remove the air cleaner
Driving with the air cleaner removed may cause excessive engine wear due
to dirt in the air. Also a backfire could cause a fire in the engine compart-
ment.
■ If the brake 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 brake fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious pro\
blem.

CAUTION
■When filling the reservoir
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately.
If you still experience discomfort, see a doctor.
