Driving assist systems
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)
Maintains drive power and prevents the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■AUTO LSD function (2WD models)
The AUTO LSD function is activated when the system is in TRAC off
mode. It operates when one of the drive wheels is spinning, such as
when the wheel is spinning freely on ice or mud. The system applies
the brakes to the spinning wheel and transfers some of the torque to
the other wheel to secure drive power.
■Active Torque Control 4W D system (4WD models)
Automatically switches from front-wheel drive to four-wheel drive
(4WD) according to the driving conditions, helping to ensure reliable
handling and stability. Examples of conditions where the system will
switch to 4WD are when cornering, going uphill, starting off or acceler-
ating, and when the road surface is slippery due to snow, rain, etc.
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.

■Automatic reactivation of TRAC and VSC
Vehicles without smart key system
Turning the engine switch OFF after turning off the TRAC and VSC systems
will automatically re-enable them.
Vehicles with smart key system
Turning the “ENGINE START STOP” switch OFF after turning off the TRAC
and VSC systems will automatically re-enable them.
■ Automatic TRAC reactivation
2WD models
If only the TRAC system is turned off, the TRAC system will be reactivated
while vehicle speed is increased. 4WD models
If only the TRAC system is turned off, the TRAC system will turn on when
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 and VSC
●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 when the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ When the AUTO LSD function operates continuously
The brake actuator may overheat. In that case, the system will stop the
AUTO LSD function, a buzzer will sound and the slip indicator will stay on
steady. Refrain from using the AUTO LSD function until the slip indicator
goes off. (There is no problem with continuing driving normally.)

Hill-start assist control
■Hill-start assist control operating conditions
• The shift lever is in a position other than P.
• The parking brake is not applied.
• The accelerator pedal is not depressed.
■ Hill-start assist control
●While hill-start assist control is operating, the brakes remain automati-
cally applied after the driver releases the brake pedal. The stop lights and
the high mounted stoplight turn on.
● Hill-start assist control operates for about 2 seconds after the brake pedal
is released.
● If the slip indicator does not flash and the buzzer does not sound when
the brake pedal is further depressed, slightly reduce the pressure on the
brake pedal (do not allow the vehicl e to roll backward) and then firmly
depress it again. If the system still does not operate, check if the operat-
ing conditions explained above have been met.
Hill-start assist control helps to prevent the vehicle from rolling
backwards when starting on an incline or slippery slope.
To engage hill-start assist con-
trol, further depress the brake
pedal when the vehicle is
stopped completely.
A buzzer will sound once to
indicate the system is acti-
vated. The slip indicator will
also start flashing.

■Conditions in which the downhill assi st control system does not oper-
ate or will stop operating
● In the following situations, the downhill assist control system indicator
flashes and the downhill assist control system does not operate or will
stop operating:
• The shift lever is not in L or R.
• The vehicle speed is higher than 15 mph (25 km/h).
● If the accelerate or brake pedal is depressed, the downhill assist control
system will stop operating with the downhill assist control system indica-
tor stayed on.
■ If the “DAC” switch is turned off while the downhill assist control sys-
tem is operating
The downhill assist control system gradually ceases operation. The downhill
assist control system indicator will flash during the canceling operation, and
then go off when the system is fully off.
■ Downhill assist control system operation sound
●A sound may be heard from the engine compartment while the downhill
assist control system is operating. This sound does not indicate a mal-
function.
● If the accelerator or brake pedal is depressed while the downhill assist
control system is operating, a sound caused by the release of system
operation may be heard, or you may feel the brake pedal push-back. This
does not indicate a malfunction.
■ When the downhill assist contro l system operates continuously
The brake actuator may overheat. In that case, the downhill assist control
system will stop operating, a buzzer will sound and the downhill assist con-
trol system indicator will start flashing. Refrain from using the system until
the downhill assist control system indicator stays on. (There is no problem
with continuing driving normally.)
■ If the slip indicator comes on
It may indicate a malfunction in the system. Contact your Toyota dealer.

Four-wheel drive lock switch (4WD models)
■Four-wheel drive lock mode can be operated when
Vehicles without smart key system
The engine switch is in the “ON” position. Vehicles with smart key system
The “ENGINE START STOP” switch is in IGNITION ON mode.
■ Four-wheel drive lock mode
●Four-wheel drive lock mode is canceled when the brakes are applied to
ensure the ABS and VSC systems operate effectively.
● Four-wheel drive lock mode is canceled when the vehicle speed exceeds
25 mph (40 km/h).
Four-wheel drive lock mode can be used when a large amount of
drive power needs to be applied to all the wheels, such as when the
vehicle gets stuck in mud and you need to free it.
Press the switch.
The torque of the engine is dis-
tributed to the rear wheels to
the maximum extent possible
in accordance with driving con-
ditions.
Pressing the switch again can-
cels four-wheel drive lock
mode and returns the Active
Torque Control 4WD system to
normal mode. (P. 184)

CAUTION
■Capacity and distribution
●Do not exceed the maximum axle weight rating or the total vehicle
weight rating.
●Even if the total load of occupant's weight and the cargo load is less
than the total load capacity, do not apply the load unevenly.
Improper loading may cause deterioration of steering or braking con-
trol which may cause death or serious injury.
■Roof luggage carrier precautions
When you load cargo on the roof luggage carrier, observe the following:
●Place the cargo so that its weight is distributed evenly between the
front and rear axles.
●If loading long or wide cargo, never exceed the vehicle overall length
or width. (P. 474)
●Before driving, make sure the cargo is securely fastened on the roof
luggage carrier.
●Loading cargo on the r oof luggage carrier will make the center of the
vehicle gravity higher. Avoid high speeds, sudden starts, sharp turns,
sudden braking or abrupt maneuvers, otherwise it may result in loss of
control or vehicle rollover due to failure to operate this vehicle correctly
and result in death or serious injury.
●If driving for a long distance, on rough roads, or at high speeds, stop
the vehicle now and then during the trip to make sure the cargo
remains in its place.
●Do not exceed 102.6 lb. (46.2 kg ) cargo weight on the roof luggage
carrier.
■Cross rail adjustment
Make sure the cross rails are locked securely by pushing forward and
rearward them.
Failure to do so may cause an unexpected accident or severe injury in
the event of emergency braking or a collision.

220 2-5. Driving information
Trailer towing tipsYour vehicle will handle differently w hen towing a trailer. In order to
avoid accident, death or serious in jury, 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.
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.
■ Brakes
Toyota recommends trailers with brakes that conform to all applicable fed-
eral and state/provincial regulations.
■ 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.

When driving
●
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.
● Note that when making a turn, th e trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a larger than normal turning radius.
● Crosswinds and rough roads will adversely affect handling of your
vehicle and trailer, causing sway . Periodically check the rear to
prepare for being passed by large trucks or buses, which may
cause your vehicle and trailer to sway. If swaying occurs, firmly grip
the steering wheel, reduce speed immediately but gradually, and
steer straight ahead. Never increase speed. If you make no
extreme correction with the stee ring or brakes, your vehicle and
trailer will stabilize.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.
● In order to maintain efficient engine braking and electrical charging
performance, do not use overdrive.
