updated by performing the following pro- cedure.
1 Stop the vehicle on a level surface.
2 Press the “ODO TRIP” switch to change the odometer and trip meter
display to odometer.
3 Turn the power switch off.
4 While pressing and holding the “ODO TRIP” switch, turn the power switch to ON.
5 Continue to hold the “ODO TRIP”
switch for approximately 5 seconds, and then release it once the odome-ter begins flashing.
Updating is complete once the odometer flashes for approximately 5 seconds and then the display returns to normal.
■Outside temperature display
●Displays the outside temperature within the range of -40°C (-40°F) to
60°C (140°F).
●When the outside temperature is
approximately 3°C (37°F) or lower,
the indicator will flash for approxi-
mately 10 seconds, then stay on.
●In the following situations, the correct
outside temperature may not be dis- played, or the display may take longer than normal to change:
• When stopped, or driving at low speeds (less than 12 mph [20 km/h])• When the outside temperature has
changed suddenly (at the entrance/exit of a garage, tunnel, etc.)
●When “--” or “E” is displayed, the sys-tem may be malfunctioning. Take your vehicle to your Toyota dealer.

WARNING
■The information display at low
temperatures
Allow the interior of the vehicle to warm up before using the liquid crys-
tal information display. At extremely low temperatures, the information dis-play monitor may respond slowly, and
display changes may be delayed.
For example, there is a lag between
the driver’s shifting and the new gear number appearing on the display. This lag could cause the driver to
downshift again, causing rapid and excessive engine braking and possi-bly an accident resulting in death or
injury.
NOTICE
■To prevent damage to the engine
and its components
The engine may be overheating if
“Engine Coolant Temp High Stop in a Safe Place See Owner’s Manual” is shown on the multi-information dis-
play. In this case, immediately stop the vehicle in a safe place, and check the engine after it has cooled com-
pletely. ( P.578)

WARNING
■When driving the vehicle
●Do not drive if you are unfamiliar
with the location of the brake and accelerator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accel- erator pedal instead of the brake pedal will result in sudden accelera-
tion that may lead to an accident.
• When backing up, you may twist your body around, leading to a diffi-
culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving
posture even when moving the vehicle only slightly. This allows you to depress the brake and accel-
erator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake
pedal using your left foot may delay response in an emergency, result-ing in an accident.
●The driver should pay extra atten-tion to pedestrians when the vehicle
is powered only by the electric motor (traction motor). As there is no engine noise, the pedestrians
may misjudge the vehicle’s move- ment. Even though the vehicle is equipped with the Acoustic Vehicle
Alerting System, drive with care as pedestrians in the vicinity may still not notice the vehicle if the sur-
rounding area is noisy.
●Do not drive the vehicle over or
stop the vehicle near flammable materials such as leaves, paper or rags.
The exhaust system and exhaust gases can be extremely hot. These hot parts may cause a fire if there is
any flammable material nearby.
●During normal driving, do not turn off the hybrid system. Turning the hybrid system off while driving will
not cause loss of steering or brak- ing control. However, power assist for the steering wheel may be lost
making it difficult to steer smoothly before stopping the vehicle depend-ing on the remaining charge in the
12-volt battery or usage conditions. In this situation, you should pull over and stop the vehicle as soon
as it is safe to do so. In the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way: P.526
●Use engine braking (downshift) to
maintain a safe speed when driving down a steep hill.Using the brakes continuously may
cause the brakes to overheat and lose effectiveness. ( P.315)
●Do not adjust the position of the steering wheel, the seat, or the inside or outside rear view mirrors
while driving. Doing so may result in a loss of vehicle control.
●Always check that all passengers’ arms, head or other parts of their
body are not outside the vehicle.
■When driving on slippery road
surfaces
●Sudden braking, acceleration and steering may cause tire slippage
and reduce your ability to control the vehicle.
●Sudden acceleration, engine brak-ing due to shifting, or changes in engine speed could cause the vehi-
cle to skid.

Driving
WARNING
●After driving through a puddle, lightly depress the brake pedal to
make sure that the brakes are func- tioning properly. Wet brake pads may prevent the brakes from func-
tioning properly. If the brakes on only one side are wet and not func-tioning properly, steering control
may be affected.
■When shifting the shift lever
●Do not let the vehicle roll backward while a forward driving position is selected, or roll forward while the
shift lever is in R. Doing so may result in an accident or damage to the vehicle.
●Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmis- sion and may result in a loss of vehicle control.
●Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmis- sion and may result in a loss of vehicle control.
●Do not shift the shift lever to a driv-ing position while the vehicle is
moving backward. Doing so can damage the transmis-sion and may result in a loss of
vehicle control.
●Moving the shift lever to N while the
vehicle is moving will disengage the hybrid system. Engine braking is not available with the hybrid system
disengaged.
●Be careful not to shift the shift lever with the accelerator pedal depressed.
Shifting the shift lever to a gear other than P or N may lead to unex-pected rapid acceleration of the
vehicle that may cause an accident and result in death or serious injury. Doing so can damage the transmis-
sion and may result in a loss of vehicle control.
■If you hear a squealing or scrap-ing noise (brake pad wear indica-tors)
Have the brake pads checked and replaced by any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer as soon as possible.Rotor damage may result if the pads
are not replaced when needed. It is dangerous to drive the vehicle when the wear limits of the brake
pads and/or those of the brake discs are exceeded.
■When the vehicle is stopped
●Do not depress the accelerator pedal unnecessarily.
If the vehicle is in any gear other than P or N, the vehicle may accel-erate suddenly and unexpectedly,
causing an accident.
●In order to prevent accidents due to
the vehicle rolling away, always keep depressing the brake pedal while stopped with the “READY”
indicator is illuminated, and apply the parking brake as necessary.
●If the vehicle is stopped on an incline, in order to prevent acci-dents caused by the vehicle rolling
forward or backward, always depress the brake pedal and securely apply the parking brake as
needed.

Driving
WARNING
●The brake system consists of 2 or more individual hydraulic systems;
if one of the systems fails, the other will still operate. In this case, the brake pedal should be depressed
more firmly than usual and the braking distance will increase. Have your brakes fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels excessively
when any of the tires is up in the air, or the vehicle is stuck in sand, mud, etc. This may damage the driveline
components or propel the vehicle for- ward or backward, causing an acci-dent.
NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time
during driving, as this may restrain the hybrid system output.
●Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully
in either direction and hold it there for an extended period of time.Doing so may damage the power
steering motor.
●When driving over bumps in the
road, drive as slowly as possible to avoid damaging the wheels, under-side of the vehicle, etc.
■If you get a flat tire while driving
A flat or damaged tire may cause the
following situations.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Hold the steering wheel firmly and gradually depress the brake pedal to
slow down the vehicle.
Information on what to do in case of a flat tire ( P.548, 559)
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain, etc. Doing so may cause the following serious dam-
age to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water
immersion
In the event that you drive on a
flooded road and the vehicle is flooded, be sure to 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.
●Components connected to the trac-
tion battery.
■When parking the vehicle
Always set the parking 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.

3085-1. Before driving
is especially true when driving on
wet or slippery road surfaces.
■Sudden acceleration/steering
input/cornering
Executing sharp turns when towing
may result in the trailer colliding
with your vehicle. Decelerate well in
advance when approaching turns
and take them slowly and carefully
to avoid sudden braking.
■Important points regarding
turning
The wheels of the trailer will travel
closer to the inside of the curve
than the wheels of the vehicle. To
make allowance for this, take the
turns wider than you would nor-
mally do.
■Important points regarding
stability
Vehicle movement resulting from
uneven road surfaces and strong
crosswinds will affect handling. The
vehicle may also be rocked by
passing buses or large trucks. Fre-
quently check behind when moving
alongside such vehicles. As soon
as such vehicle movement occurs,
immediately start to decelerate
smoothly by slowly applying the
brakes. Always steer the vehicle
straight ahead while braking.
■Passing other vehicles
Consider the total combined length
of your vehicle and trailer and
ensure that the vehicle-to-vehicle
distance is sufficient before execut-ing lane changes.
■Transmission information
To maintain engine braking effi-
ciency, when using engine braking,
do not use the transmission in D.
(P.315)
■If the hybrid system overheats
Towing a loaded trailer up a long,
steep incline in temperatures
exceeding 30°C (85°F) may result
in the hybrid system overheating. If
the high coolant temperature warn-
ing light indicates that the hybrid
system is overheating, turn the air
conditioning off immediately, leave
the road and stop the vehicle in a
safe place. (P.578)
■When parking the vehicle
Always place wheel chocks under
the wheels of both the vehicle and
trailer. Firmly set the parking brake
and shift the shift lever to P.
■Break-in schedule
Toyota recommends that vehicles fitted
with new power train components
should not be used for towing trailers for
the first 800 km (500 miles).
■Maintenance
●Maintenance must be performed more
frequently when using the vehicle for
towing due to the greater weight bur-
den placed on the vehicle compared
to normal driving.
●Retighten all bolts securing the hitch-
ing ball and bracket after towing for
approximately 1000 km (600 miles).
■If trailer sway occurs
One or more factors (crosswinds, pass-
ing vehicles, rough roads, etc.) can

4265-6. Driving tips
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 driving 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 brakes for effec-tiveness immediately after driving in sand, mud, water or snow.
●After driving through tall grass, mud, rock, sand, rivers, etc., check that there is no grass, bush, paper,
rags, stone, sand, etc. adhering or trapped on the underbody. Clear off any such matter from the
underbody. If the vehicle is used with these materials trapped or adhering to the underbody, a break-
down 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 water damage to the hybrid battery (traction 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 not be drivable.
●Water can wash the grease from wheel bearings, causing rusting and premature failure, and may
also enter the hybrid transaxle case, reducing the gear oil’s lubri-cating qualities.

■Does your vehicle need repairs?
Be on the alert for changes in perfor-
mance and sounds, and visual tip-offs
that indicate service is needed. Some
important clues are:
●Engine missing, stumbling or pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (How-
ever, water dripping from the air con-
ditioning system after use is normal.)
●Change in exhaust sound (This may
indicate a dangerous carbon monox-
ide leak. Drive with the windows open
and have the exhaust system checked
immediately.)
●Flat-looking tires, excessive tire
squeal when cornering, uneven tire
wear
●Vehicle pulls to one side when driven
straight on a level road
●Strange noises related to suspension
movement
●Loss of brake effectiveness, spongy
feeling brake pedal, pedal almost
touches the floor, vehicle pulls to one
side when braking
●Engine coolant temperature continu-
ally higher than normal (P.187, 193)
If you notice any of these clues, take
your vehicle to any authorized Toyota
retailer or Toyota authorized repairer, or
any reliable repairer as soon as possi-
ble.
Your vehicle may need adjustment or
repair.
