5-1. Before driving
Driving
WARNING
OThe 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.
QIf 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
QWhen driving the vehicle
ODo not depress the accelerator and brake pedals at the same time
during driving, as this may restrain the hybrid system output.
ODo not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.
QAvoiding damage to vehicle parts
ODo 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.
OWhen driving over bumps in the
road, drive as slowly as possible to avoid damaging the wheels, under-side of the vehicle, etc.
QIf you get a flat tire while driving
A flat or damaged tire may cause the
following situations.
OIt may be difficult to control your vehicle.
OThe vehicle will make abnormal sounds or vibrations.
OThe 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.522, 533)
QWhen 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:
OEngine stalling
OShort in electrical components
OEngine 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:
OBrake function
OChanges in quantity and quality of oil and fluid used for the engine,
hybrid transaxle (front and rear), etc.
OLubricant condition for the bearings and suspension joints (where possi-ble), and the function of all joints,
bearings, etc.
OComponents connected to the trac-
tion battery.
QWhen 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.
QDoes 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:
OEngine missing, stumbling or pinging
OAppreciable loss of power
OStrange engine noises
OA fluid leak under the vehicle (How-
ever, water dripping from the air con-
ditioning system after use is normal.)
OChange in exhaust sound (This may
indicate a dangerous carbon monox-
ide leak. Drive with the windows open
and have the exhaust system checked
immediately.)
OFlat-looking tires, excessive tire
squeal when cornering, uneven tire
wear
OVehicle pulls to one side when driven
straight on a level road
OStrange noises related to suspension
movement
OLoss of brake effectiveness, spongy
feeling brake pedal, pedal almost
touches the floor, vehicle pulls to one
side when braking
OEngine coolant temperature continu-
ally higher than normal (P.551)
If you notice any of these clues, take
your vehicle to any authorized Toyota

any reliable repairer as soon as possi-
ble.

Maintenance and care
WARNING
QWhen working on the engine compartment
OMake sure that “IGNITION ON” on the multi-information display and the “READY” indicator are both off.
OKeep hands, clothing and tools away from the moving fan.
OBe 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.
ODo not leave anything that may burn easily, such as paper and
rags, in the engine compartment.
ODo not smoke, cause sparks or
expose an open flame to fuel. Fuel fumes are flammable.
OTake 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.
QWhen 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.458)
QSafety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc., from getting in your eyes.
NOTICE
QIf 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.
QIf 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.

5068-2. Steps to take in an emergency
5Securely attach cables or chains
to the towing eyelet.

braking more difficult.
QWheel nut wrench (if equipped)
Wheel nut wrench is installed in the deck under tray. ( P.523, 534)
