holes or uneven surfaces
■TRC/VSC may not operate effec -
tively when
Directional control and power may not be achievable while driving on slip -
pery road surfaces , even if the
TRC/VSC system is operating.
Drive the vehicle carefully in condi - tions where stabilit y and power may
be lost.
■Active Cornering Assist does not
operate effectively when
●Do not overly rely on Active Corner - ing Assist. Active Cornering Assist
may not operate effectively when
accelerating down slopes or driving on slippery road surfaces.
●When Active Cornering Assist fre - quently operates, Active Cornering
Assist may temporarily stop operat -
ing to ensure prop er operation of the brakes, TRC and VSC.
■Hill-start assist control does not operate effectively when
●Do not overly rely on hill-start assist
control. Hill-start assist control may not operate effectively on steep
inclines and roads covered with ice.
●Unlike the parking brake, hill-start
assist control is not intended to hold
the vehicle stationary for an extended period of time. Do not
attempt to use hill-start assist con -
trol to hold the vehicle on an incline, as doing so may lead to an acci-
dent.
■When the TRC/ABS/VSC/Trailer
Sway Control is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular
care when the indicat or light flashes.
■When the TRC/VSC/Trailer Sway Control systems are turned off
Be especially careful and drive at a
speed appropriate t o the road condi- tions. As these ar e the systems to
help ensure vehicl e stability and driv-
ing force, do not turn the TRC/VSC/Trailer Sway Control sys -
tems off unle ss necessary.
Trailer Sway Control is part of the VSC system and will not operate if
VSC is turned off or experiences a
malfunction.
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern
and total load capac ity. In addition,
make sure that the tires are inflated to the recommended tire inflation pres -
sure level.
The ABS, TRC and VSC/Trailer Sway Control systems will not function cor -
rectly if different ti res are installed on
the vehicle. Contact any authorized Toyota
retailer or Toyota a uthorized repairer,
or any reliable repairer for further information when replacing tires or
wheels.
■Handling of tires and the suspen -
sion
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may
cause a system to malfunction.
■Trailer Sway Control precaution
The Trailer Sway C ontrol system is not able to reduce tr ailer sway in all
situations. Depending on many fac -
tors such as the conditions of the
vehicle, trailer, road surface and driv - ing environment, the Trailer Sway
Control system may not be effective.
Refer to your traile r owner’s manual for information on how to tow your
trailer properly.

4445-5. Using the driving support systems
WARNING
■If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or serious injury.
●Firmly grip the steering wheel.
Steer straight ahead. Do not try to control trailer sw aying by turning
the steering wheel.
●Begin releasing the accelerator pedal immediately but very gradu -
ally to reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction
with the steering or brakes, your vehi-
cle and trailer should stabilize.
( →P.308)
■Secondary Collision Brake (if
equipped)
Do not rely solely upon the Secondary Collision Brake. This system is
designed to help re duce the possibil-
ity of further damage due to a second - ary collision, however, that effect
changes according to various condi -
tions. Overly relyi ng on the system may result in death or serious injury.

Pre-winter preparations
WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of
vehicle control and cause death or serious injury.
●Use tires of the specified size.
●Maintain the recommended level of air pressure.
●Do not drive at speeds in excess of the speed limit or the speed limit
specified for the snow tires being
used.
●Use snow tires on all, not just some
wheels.
■Driving with tire chains (except
235/55R19 tires)
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in the vehi - cle being unable to be driven safely,
and may cause death or serious
injury.
●Do not drive in excess of the speed
limit specified for the tire chains being used, or 50 km/h (30 mph),
whichever is lower.
●Avoid driving on bumpy road sur -
faces or over potholes.
●Avoid sudden acceleration, abrupt
steering, sudden br aking and shift-
ing operations that cause sudden engine braking.
●Slow down sufficiently before enter - ing a curve to ensure that vehicle
control is maintained.
●Do not use LTA (Lane Tracing
Assist) system (if equipped).
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer or legitimate tire retailers.
This is because the removal and
attachment of snow tires affects the operation of the tire pressure warning
valves and transmitters.

4465-6. Driving tips
Perform the following according to
the driving conditions:
 Do not try to forcibly open a win-
dow or move a wiper that is fro -
zen. Pour warm water over the
frozen area to melt the ice. Wipe
away the water immediately to
prevent it from freezing.
 To ensure proper operation of
the climate control system fan,
remove any sno w that has accu-
mulated on the air inlet vents in
front of the windshield.
 Check for and remove any
excess ice or snow that may
have accumulated on the exte -
rior lights, vehicle’s roof, chassis,
around the tires or on the brakes.
 Remove any snow or mud from
the bottom of your shoes before
getting in the vehicle.
Accelerate the veh icle slowly, keep
a safe distance between you and
the vehicle ahead, and drive at a
reduced speed suitable to road
conditions.
 Park the vehicle and move the
s hif t le ve r to P w itho u t se tt ing th e
parking brake. The parking brake
may freeze up, preventing it from
being released. If the vehicle is
parked without setting the park -
ing brake, make sure to block the
wheels.
Failure to do so may be danger -
ous because it may cause the
vehicle to move unexpectedly,
possibly leading to an accident.
When the parking brake is in automatic
mode, release the parking brake after
shifting the shift lever to P. ( →P.326)
If the vehicle is left parked with
the brakes damp in cold tem -
peratures, there is a possibility of
the brakes freezing.
 If the vehicle is parked without
setting the parking brake, con -
firm that the shift lever cannot be
moved out of P*.
*: The shift lever will be locked if it is
attempted to be shifted from P to any
other position with out depressing the
brake pedal. If the shift lever can be
shifted from P, t here may be a prob-
lem with the shift lock system. Have
the vehicle inspected by any autho -
rized Toyota retailer or Toyota autho -
rized repairer, or any reliable repairer
immediately.

WARNING
■When parking the vehicle
When parking the vehicle without
applying the parki ng brake, make
sure to chock the wheels. If you do
not chock the wheels, the vehicle may move unexpectedly, possibly result-
ing in an accident.

4485-6. Driving tips
Specific design characteristics
give it a higher center of gravity
than ordinary passenger cars.
This vehicle design feature
causes this type of vehicle to be
more likely to rollover. And, utility
vehicles have a significantly
higher rollover rate than other
types of vehicles.
 An advantage of the higher
ground clearance is a better view
of the road allowing you to antici -
pate problems.
 It is not designed for cornering at
the same speeds as ordinary
passenger cars any more than
low-slung sports cars are
designed to perform satisfactorily
under off-road conditions. There -
fore, sharp turns at excessive
speeds may cause the vehicle to
rollover.
When driving your vehicle off-road,
please observe the following pre -
Utility vehicle precau-
tions
This vehicle belongs to the
utility vehicle class, which has
higher ground clearance and
narrower tread i n relation to
the height of its center of grav -
ity to make it capable of per -
forming in a wide variety of off-
road applications.
Utility vehicle feature
WARNING
■Utility vehicle precautions
Always observe the following precau -
tions to minimize the risk of death, serious injury or damage to your vehi-
cle:
●In a rollover crash, an unbelted per - son is significantly more likely to die
than a person wearing a seat belt.
Therefore, the driver and all pas -
sengers should alwa ys fasten their seat belts.
●Avoid sharp turns or abrupt maneu - vers, if at all possible.
Failure to operate this vehicle cor-
rectly may result in loss of control or vehicle rollover causing death or
serious injury.
●Loading cargo on the roof luggage
carrier (if equipped) 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.
●Always slow down in gusty cross -
winds. Because of its profile and higher center of gravity, your vehi -
cle is more sensitive to side winds
than an ordinary passenger car. Slowing down will allow you to have
better control.
●Do not drive horizontally across
steep slopes. Driving straight up or
straight down is preferred. Your vehicle (or any sim ilar off-road vehi-
cle) can tip over sideways much
more easily than forward or back- ward.
Off-road driving
