When driving
■The intuitive parking assist system can be operated when
●The engine switch is at the ON position.
● The shift lever is in R.
■ 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.

When driving
Manual transmission
Before using the rear differential lock system.
Stop the vehicle or reduce your speed to less than 5 mph (8
km/h). Depress the clutch pedal and shift the four-wheel drive
control lever into LL to see if this is sufficient. If this has no
effect, additionally use the r ear differential lock system.
Be sure to stop the wheels.
Depress the clutch pedal.
Press the RR DIFF LOCK switch.
Slowly release the clutch pedal.
After the rear differential is locked, the indicator will come on.
Unlock the rear differential as soon as the vehicle moves.
To unlock the rear differential, push the switch again.
■ Locking the rear differential
●When the rear differential is locked, VSC is automatically turned off.
(The rear differential lock and VSC OFF indicators will come on.)
● The following systems do not operate when the rear differential is locked.
It is normal operation for the ABS warning light and VSC OFF indicator to
be on at this time.
•ABS
• Brake assist system
•VSC
•TRAC
■ The rear differential lock is disengaged when
●Shift the four-wheel drive control lever to H or HL. (4WD models with a
manual transmission)
● Shift the front-wheel drive control lever to H2 or H4. (4WD models with
an automatic transmission)
Never forget to turn off the switch after using this feature.
■ After unlocking the rear differential
Check that the indicator goes off.

■Crawl Control can be operated when
●The engine is running.
● The shift lever is in any position other than P or N.
● The front-wheel drive control lever is in L4.
● The driver’s door is closed.
■ Crawl Control is temp orarily canceled when
Vehicle speed exceeds 15 mph (25 km/h). The Crawl Control indicator
flashes until the vehicle speed is reduced.
■ Automatic system cancelation
In the following situations, the system will cease operation and a buzzer will
sound to alert the driver. The Crawl Control indicator will flash until the sys-
tem is turned off completely.
●When the shift lever is shifted to P or N
● When the front-wheel drive control lever is shifted to H4
● When the driver’s door is opened
● When the system is malfunctioning
● When the brake system overheats
Stop the vehicle in a safe place. (There is no problem with continuing
normal driving.)
● When the automatic transmission system overheats
Stop the vehicle in a safe place until the automatic transmission fluid tem-
perature warning light goes off.
■ Sounds and vibrations caused by the Crawl Control system
● A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate that a malfunction has occurred in Crawl Control system.
● Either of the following conditions may occur when the Crawl Control sys-
tem is 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.

Driving assist systems
When TRAC/VSC are operatingThe slip indicator light will flash
while the TRAC/VSC systems
are operating.
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too h eavily when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface.
■Brake Assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
■TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads.

When driving
■Automatic VSC reactivation (2WD models)
If only the TRAC system is turned off, VSC OFF and AUTO LSD indicators
turn on. The VSC system will turn on when the vehicle speed increases.
■ Automatic TRAC and VSC reactivation
If the TRAC and VSC systems are turned off, the systems will not turn on,
even when vehicle speed increases.
■ Sounds and vibrations caused by the ABS, TRAC, VSC and brake
assist system
●A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate 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 will cease operation and a buzzer will sound to alert the driver. Stop
the vehicle in a safe place. (There is no problem with continuing normal driv-
ing.)
CAUTION
■ The ABS does not opera te effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on the wet or slick
road.

Maintenance and care
NOTICE
■
If you remove the air cleaner
Driving with the air cleaner removed may cause excessive engine wear due
to dirt in the air.
■ 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 pro\
blem.

■Brake fluid can absorb moisture from the air
Excess moisture in the fluid can cause a dangerous loss of braking effi-
ciency. 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 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.
