■Hill-start assist control operation conditions
● The shift lever is in D or S.
● The brake pedal is not depressed.
● The rear differential is unlocked (if equipped).
■ If the brake system overheats
The hill-start assist control will cease operation and a buzzer will sound to
alert the driver. At this time, the “TRAC OFF (TRC OFF)” indicator will come
on. Stop the vehicle in a safe place. (There is no problem with continuing
with normal driving.)
The system will be automatically restored after a short time.
■ Sounds and vibrations caused by the ABS, Multi Terrain ABS (if
equipped), brake assist, VSC, TRAC (TRC) and hill-start assist control
(if equipped) systems
● 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 or Multi Terrain
ABS is activated.
• The brake pedal may move down slightly after the ABS or Multi Terrain ABS is activated.
■ Reactivation of the TRAC (TRC)/VSC systems after turning off the
engine
Turning off the engine after turning off the TRAC (TRC)/VSC systems will
automatically reactivate them.
■ Reactivation of the VSC system linked to vehicle speed (2WD models)
When the TRAC system is turned off and the AUTO LSD system is turned
on, the VSC system will turn on when vehicle speed increases. However,
when the TRAC and VSC systems are turned off, the systems will not turn
on even when vehicle speed increases.

CAUTION
■When the VSC is activated
The slip indicator light flashes and a warning buzzer sounds. Always drive
carefully.
Reckless driving may cause an accident. Exercise particular care when the
indicator light flashes and a buzzer sounds.
■ When TRAC (TRC)/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are systems to ensure vehicle stability and driving force, do
not turn the TRAC (TRC)/VSC systems off unless necessary.
■ Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, Multi Terrain ABS and VSC will not function correctly if different
tires are fitted on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

Selecting a trailer ball
Use the correct trailer ball for your application. Trailer ball load rating
Matches or exceeds the gross
trailer weight rating of the trailer.
Ball diameter
Matches the size of the trailer
coupler. Most couplers are
stamped with the required trailer
ball size.
Shank length
Protrudes beyond the bottom of
the lock washer and nut at least 2
threads.
Shank diameter
Matches the ball mount hole
diameter size.
Connecting trailer lights

Trailer towing tipsYour vehicle will handle differently when towing a trailer. The 3 main
causes of vehicle-trailer accidents are driver error, excessive speed
and improper trailer loading. Keep the following in mind when towing.
● Before starting out, check the trailer lights and the vehicle-trailer
connections. Recheck after driving a short distance.
● Practice turning, stopping and reve rsing with the trailer attached in
an area away from traffic until you become accustomed to the feel
of the vehicle.
● Reversing with a trailer attached is difficult and requires practice.
Grip the bottom of the steering wheel and move your hand to the
left to move the trailer to the left. Move your hand to the right to
move the trailer to right. (This is generally opposite to reversing
without a trailer attached.) Avoid sharp or prolonged turning. Have
someone guide you when reversing to reduce the risk of an acci-
dent.
● As stopping distance is increased when towing a trailer, vehicle-to
vehicle distance should be increased. For each 10 mph (16 km/h)
of speed, allow at least o ne vehicle and trailer length.
● Avoid sudden braking as you may skid, resulting in jackknifing and
loss of control. This is especiall y true on wet or slippery surfaces.
● Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before mak-
ing turns.

■ Before towing
Check that the following conditions are met:
● The vehicle’s tires are properly inflated.
● Trailer tires are inflated according to the trailer manufacturer’s recom-
mendation.
● All trailer lights work.
● All lights work each time you connect them.
● The trailer ball is set up at the proper height for the coupler on the t\
railer.
● The vehicle remains level when a loaded or unloaded trailer is hitched.
Do not drive if the vehicle is not level, and check for improper tongue
load, overloading, worn suspension, or other possible causes.
● The trailer cargo is securely loaded.
● The rear view mirrors conform to all applicable federal, state/provincial or
local regulations. If they do not, install rear view mirrors appropriate for
towing purposes.
■ Break-in schedule
If your vehicle is new or equipped with any new power train components
(such as an engine, transmission, differential and wheel bearing), Toyota
recommends that you do not tow a trailer until it has been driven for over 500
miles (800 km).
However, avoid full throttle acceleration.
Your vehicle is equipped with a service
connector for the trailer brake controller
as shown.

CAUTION
■
Hitches
● If you wish to install a trailer hitch, contact your Toyota dealer.
● Use only a hitch that conforms to the gross trailer weight requirement.
● Follow the directions supplied by the hitch manufacturer.
● Lubricate the hitch ball with a light coat of grease.
● Remove the trailer hitch whenever you are not towing a trailer. After
removing the hitch, seal any mounting hole in the vehicle body to prevent
entry of any substances into the vehicle.
■ When towing a trailer
● If the gross trailer weight exceeds 1000 lb. (453 kg), trailer brakes are
required. Toyota recommends trailers wi th brakes that conform to all appli-
cable federal and state/provincial regulations.
● Never tap into your vehicle’s hydraulic system, as this will lower the vehi-
cle’s braking effectiveness.
● Never tow a trailer without using a safety chain securely attached to both
the trailer and the vehicle. If damage occurs to the coupling unit or hitch
ball, there is a risk of the trailer wandering into another lane.

NOTICE
■When installing a trailer hitch
● Use only the position recommended by your Toyota dealer. Do not install
the trailer hitch on the bumper; this may cause body damage.
● Do not use axle-mounted hitches, as they can cause damage to the axle
housing, wheel bearings, wheels or tires.
■ Safety chain
A safety chain must always be used between the towing vehicle and the
trailer. Leave sufficient slack in the chain for turns. The chain should cross
under the trailer tongue to prevent the tongue from dropping to the ground in
the case that it becomes damaged or separated. For the correct safety chain
installation procedure, ask your Toyota dealer.
■ Do not directly splice trailer lights
Directly splicing trailer lights may damage your vehicle’s electrical system
and cause a malfunction.
