Driving
NOTICE
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage 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 authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional check the following:
● Brake function
● Changes in quantity and quality of oil and fluid used for the engine, hybrid
transmission, etc.
● Lubricant condition for the bearings and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.
If the shift control system is damaged by flooding, it may not be possible to
shift the shift position to P, or from P to other positions. When the shift posi-
tion cannot be changed from P to any other position, the front wheels will
lock, and you will be unable to tow the vehicle with the front wheels on the
ground, as the front wheels may be locked. In this case, transport the vehi-
cle with both front wheels or all four wheels lifted.

4985-6. Driving tips
PRIUS PHV_OM_OM47A89E_(EE)
Winter driving tips
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine/power control unit coolant
• Washer fluid
●Have a service technician inspect the condition of the 12-volt bat-
tery.
●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.
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
●To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
●Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
●Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.

5587-2. Maintenance
PRIUS PHV_OM_OM47A89E_(EE)
■Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Toyota recom-
mends that maintenance service operations as well as other inspections and
repairs be carried out by authorized Toyota dealers or repairers or other duly
qualified and equipped professionals. For repairs and services covered by
your warranty, please visit an authorized Toyota dealer or repairer, who will
use genuine Toyota parts in repairing any difficulties you may encounter.
There can also be advantages in utilizing authorized Toyota dealers or repair-
ers for non-warranty repairs and services, as members of the Toyota network
will be able to expertly assist you with any difficulties you may encounter.
Your Toyota dealer or repairer, or another duly qualified and equipped profes-
sional will perform all of the scheduled maintenance on your vehicle reliably
and economically due to their experience with Toyota vehicles.
■Does your vehicle need repairs?
Be on the alert for changes in performance 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 (However, water dripping from the air condi-
tioning system after use is normal.)
●Change in exhaust sound (This may indicate a dangerous carbon monoxide
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 continually higher than normal (P. 644, 688)
If you notice any of these clues, take your vehicle to any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional as
soon as possible. Your vehicle may need adjustment or repair.

Maintenance and care
WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become el ectrically energized. To avoid death
or serious injury, observe the following precautions.
■ When working on the engine compartment
● Make sure that the “Accessory”, “Ignition ON” or mileage display (P. 208)
on the main 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 fluids
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.
● Be extremely cautious when working on the 12-volt battery. It contains poi-
sonous and corrosive sulfuric acid.
● Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with clean water immediately. If you still experience discom-
fort, consult a doctor.
■ When working near the electric cooling fans or radiator grille
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature
is high. ( P. 572)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.

PRIUS PHV_OM_OM47A89E_(EE)
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.
■ If the brake 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 refilling, it may indicate a serious problem.
