4-1. Before driving
WARNING
■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 no t sh i ft t h e sh if t l e ve r t o R whi l e 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 any positions other than P or N may lead to unexpected rapid accelera-
tion of the vehicle that may cause an accident and result in death or serious injury.
■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 shift lever is any position 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.
●Avoid revving or racing the engine.Running the engine at high speed
while the vehicle is stopped may cause the exhaust system to over-heat, which could result in a fire if
combustible material is nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehicle when it is in the
sun. Doing so may result in the follow-ing:
• Gas may leak from a cigarette lighter or spray can, and may lead
to a fire.
• The temperature inside the vehicle
may cause the plastic lenses and plastic material of glasses to deform or crack.

tor pedal depressed, the engine
WARNING
■If the vehicle becomes stuck (AWD models)
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.
■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.
■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. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.

flat tire ( P.448, 459)
■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
becomes flooded or stuck in mud or sand, be sure to have any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer check the following:
●Brake function
●Changes in quantity and quality of
oil and fluid used for the engine, hybrid transmission, differential, etc.
●Lubricant condition for the bearings and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.

4-1. Before driving
Driving
at a time to prevent steering
error. Have someone guide you
when reversing to lessen the risk
of an accident.
■Increasing vehicle-to-vehicle
distance
At a speed of 10 km/h (6 mph), the
distance to the vehicle running
ahead of you should be equivalent
to or greater than the combined
length of your vehicle and trailer.
Avoid sudden braking that may
cause skidding. Otherwise, the
vehicle may spin out of control. This
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 and charging system perfor-
mance when using engine braking,
do not use the transmission in D.
( P.197)
■If the engine overheats
Towing a loaded trailer up a long,
steep incline in temperatures
exceeding 30°C (85°F) may result
in the engine overheating. If the
engine coolant temperature gauge
indicates that the engine is over-
heating, turn the air conditioning off
immediately, leave the road and
stop the vehicle in a safe place.
( P.477)
■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.

completely stopped.
*: For the vehicle be able to be shifted
from P, the brake pedal must be
depressed before the shift release
button is pushed. If the shift release
button is pushed first, the shift lock
will not be released.
■Shift lock system
The shift lock system is a system to pre- vent accidental operation of the shift
lever in starting. The shift lever can be shifted from P only when the power switch is in ON and
the brake pedal is being depressed.
■If the shift lever cannot be shifted from P
First, check whether the brake pedal is
being depressed. If the shift lever cannot be shifted with your foot on the brake pedal, there may
be a problem with the shift lock system. Have the vehicle inspected by any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer immediately.
The following steps may be used as an emergency measure to ensure that the
WARNING
■When driving on slippery road surfaces
Do not accelerate or shift gears sud- denly. Sudden changes in engine braking
may cause the vehicle to spin or skid, resulting in an accident.
NOTICE
■Hybrid battery (traction battery) charge
If the shift lever is in N, the hybrid bat-
tery (traction battery) will not be charged even when the engine is run-ning. Therefore, if the vehicle is left
with the shift lever in N for a long period of time, the hybrid battery (traction battery) will discharge, and
this may result in the vehicle not being able to start.
