5-1. Before driving
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.

Maintenance and care
request that a record of maintenance
be kept.
■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.

Maintenance and care
WARNING
■When working on the engine compartment
●Make sure that “IGNITION ON” on the multi-information display and the “READY” indicator are both off.
●Keep hands, clothing and tools away from the moving fan.
●Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other flu-ids may also be hot.
●Do not leave anything that may burn easily, such as paper and
rags, in the engine compartment.
●Do not smoke, cause sparks or
expose an open flame to fuel. Fuel fumes are flammable.
●Take care because brake fluid can harm your hands or eyes and dam-age painted surfaces. If fluid gets
on your hands or in your eyes, flush the affected area with clean water immediately. If you still experience
discomfort, consult a doctor.
■When working near the electric
cooling fan or radiator grille
Be sure the power switch is off. With the power switch in ON, the
electric cooling fan may automatically start to run if the air conditioning is on and/or the coolant temperature is
high. ( P.482)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc., from getting in your eyes.
NOTICE
■If you remove the air cleaner fil-ter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to
go down slightly as the brake pads wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refill- ing, it may indicate a serious problem.

5348-2. Steps to take in an emergency
■Brake system warning light (warning buzzer)
■Brake system warning light
If a warning light turns on or a warning buzzer sounds

However, if this continues to occur, have the vehicle inspected by
any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer.
