3065-1. Before driving
NOTICE
In the event that you drive on a
flooded road and the vehicle is
flooded, be sure t o have any autho- rized Toyota retailer or Toyota autho -
rized repairer, or any reliable repairer
check the following:
●Brake function
●Changes in quantity and quality of
oil and fluid used for the engine, hybrid transaxle (front and rear),
etc.
●Lubricant condition for the bearings
and suspension joints (where possi -
ble), and the function of all joints, bearings, etc.
■When parking the vehicle
Always set the park ing brake, and
shift the shift lever to P. Failure to do
so may cause the vehicle to move or the vehicle may accelerate suddenly
if the accelerator pedal is accidentally
depressed.
Cargo and luggage
Take notice of the following
information about storage pre -
cautions, cargo capacity and
load.
WARNING
■Things that must not be carried
in the luggage compartment
The following things may cause a fire if loaded in the luggage compartment:
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failure to do so m ay prevent the ped-
als from being depressed properly, may block the driver’s vision, or may
result in items hitting the driver or
passengers, possibly causing an acci - dent.
●Stow cargo and l uggage in the lug-
gage compartment whenever pos - sible.
●Do not stack anything in the lug - gage compartment higher than the
seatbacks.
●When you fold down the rear seats,
long items should not be placed
directly behind the front seats.
●Never allow anyone to ride in the
luggage compartment. It is not designed for passengers. They
should ride in their seats with their
seat belts properl y fastened. Other- wise, they are much more likely to
suffer death or serious bodily injury,
in the event of sudden braking, sud - den swerving or an accident.

 Use fluids that are appropriate to
the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Power control unit coolant
• Washer fluid
 Have a service technician
inspect the condition of the 12-
volt battery.
 Have the vehicle fitted with four
snow tires or purchase a set of
tire chains for the front tires.
Ensure that all tires are the same size
and brand, and that chains match the
size of the tires.*
*: Tire chains cannot be mounted on
vehicles with 235/55R19 tires.
Winter driving tips
Carry out the necessary prepa -
rations and inspections before
driving the vehicle in winter.
Always drive the vehicle in a
manner appropriate to the pre -
vailing weather conditions.
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.

Driving
cautions to ensure your driving
enjoyment and to help prevent the
closure of areas to off-road vehi -
cles:
 Drive your vehicle only in areas
where off-road vehicles are per -
mitted to travel.
 Respect private property. Get
owner’s permission before enter -
ing private property.
 Do not enter areas that are
closed. Honor gates, barriers
and signs that restrict travel.
 Stay on established roads. When
conditions are wet, driving tech -
niques should be changed or
travel delayed to prevent dam -
age to roads.
WARNING
■Off-road drivin g precautions
Always observe the following precau -
tions to minimize the risk of death, serious injury or damage to your vehi -
cle:
●Drive carefully when off the road. Do not take unnecessary risks by
driving in dangerous places.
●Do not grip the steering wheel
spokes when driving off-road. A
bad bump could jerk the wheel and injure your hands. Keep both hands
and especially your thumbs on the
outside of the rim.
●Always check your b rakes for effec-
tiveness immediately after driving in sand, mud, water or snow.
●After driving through tall grass, mud, rock, sand, ri vers, etc., check
that there is no g rass, bush, paper,
rags, stone, sand, etc. adhering or trapped on the underbody. Clear off
any such matter from the under -
body. If the vehi cle is used with these materials trapped or adhering
to the underbody, a breakdown or
fire could occur.
●When driving off-road or in rugged
terrain, do not drive at excessive speeds, jump, make sharp turns,
strike objects, etc. This may cause
loss of control or vehicle rollover causing death or serious injury. You
are also risking expensive damage
to your vehicle’s suspension and chassis.
NOTICE
■To prevent the water damage
Take all necessary safety measures
to ensure that wat er damage to the hybrid battery (tr action battery),
hybrid system or other components
does not occur.
●Water entering the engine compart -
ment may cause severe damage to
the hybrid system.
●Water entering the hybrid transmis -
sion will cause deterioration in transmission quality. The malfunc -
tion indicator may come on, and the
vehicle may no t be drivable.
●Water can wash the grease from
wheel bearings, causing rusting and premature fa ilure, and may
also enter the h ybrid transaxle
case, reducing the gear oil’s lubri - cating qualities.

shield where the raindrop sensor is
located is tou ched by hand
●When a wet rag or similar is held
close to the raindrop sensor
●If something bum ps against the
windshield
●If you directly touch the raindrop
sensor body or if something bumps
into the raindrop sensor
■Precautions regarding the
exhaust pipes
Exhaust gasses cause the exhaust
pipes to become quite hot.
When washing the vehicle, be careful not to touch the pipes until they have
cooled sufficiently, as touching hot
exhaust pipes can cause burns.
