WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death o r serious
injury:
● Pull your vehicle off the road, apply the parking brake, shift the shift lever
to P, and turn the hybrid system off.
● Do not touch the high voltage parts, cables and connectors.
● If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
● 2ZR-FXE engine (for Guadelope, Martinique, F. Guiana and Greenland): If
a fluid leak occurs, do not touch the fluid as it may be strong alkaline elec-
trolyte from the hybrid battery (traction battery). If it comes into contact
with your skin or eyes, wash it off immediately with a large am ount of water
or, if possible, boric acid solution. Seek immediate medical at tention.
● 2ZR-FXE engine (except for Guadelope, Martinique, F. Guiana and
Greenland): Do not touch the batte ry if liquid is leaking from or adhering to
it. If electrolyte (carbonic-based organic electrolyte) from th e hybrid battery
(traction battery) comes into contact with the eyes or skin, it could cause
blindness or skin wounds. In the unlikely event that it comes i nto contact
with the eyes or skin, wash it of f immediately with a large amount of water,
and seek immediate medical attention.
● 2ZR-FXE engine (except for Guadelope, Martinique, F. Guiana and
Greenland): If electrolyte is leaking from the hybrid battery ( traction bat-
tery), do not approach the vehicle. Even in the unlikely event that the
hybrid battery (traction battery) is damaged, the internal cons truction of
the battery will prevent a large amount of electrolyte from lea king out.
However, any electrolyte that does leak out will give off a vap or. This vapor
is an irritant to skin and eyes and could cause acute poisoning if inhaled.
● 2ZR-FXE engine (except for Guadelope, Martinique, F. Guiana and
Greenland): Do not bring burning or high-temperature items close to the
electrolyte. The electrolyte may ignite and cause a fire.
● If a fire occurs in the Hybrid Electric Vehicle, leave the vehicle as soon as
possible. Never use a fire extinguisher that is not meant for e lectric fires.
Using even a small amount of water may be dangerous.
● If your vehicle needs to be towed, do so with front wheels raised. If the
wheels connected to the electric motor (traction motor) are on the ground
when towing, the motor may continue to generate electricity. Th is may
cause a fire. ( P. 672)
● Carefully inspect the ground under the vehicle. If you find that liquid has
leaked onto the ground, the fuel system may have been damaged. Leave
the vehicle as soon as possible.

2924-1. Before 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 i s flooded, be
sure to have any authorized Toyota retailer or Toyota authorize d 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, etc.

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 cha ins match
the size of the tires.
*: Tire chains cannot be mounted on 18-inch tires or 19-inch tir es.
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 ma n-
ner appropriate to the prevailing weather conditions.

Maintenance and care
■Where to go for maintenance service?
In order to maintain your vehicle in the best possible conditio n, Toyota recom-
mends that maintenance service operations as well as other insp ections and
repairs be carried out by authorized Toyota retailers or repair ers or other duly
qualified and equipped professionals. For repairs and services covered by
your warranty, please visit an authorized Toyota retailers or r epairer, who will
use genuine Toyota parts in repairing any difficulties you may encounter.
There can also be advantages in utilizing authorized Toyota ret ailers or
repairers for non-warranty repairs and services, as members of the Toyota
network will be able to expertly assist you with any difficulti es you may
encounter.
Your authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer 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 visu al tip-offs
that indicate service is needed. Some important clues are:
● Engine misses, 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 c hecked
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. 684, 755)
If you notice any of these clues, take your vehicle to any auth orized Toyota
retailer or Toyota authorized repairer, or any reliable repaire r as soon as pos-
sible. Your vehicle may need adjustment or repair.

WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
■ When working on the engine compartment
● Make sure that the “ACCESSORY” or “IGNITION ON” on the multi-infor-
mation 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 or the 12-volt
battery. Fuel and 12-volt battery 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 experi ence 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 coo lant temperature
is high. ( P. 604)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, flui d spray, etc.,
from getting in your eyes.

Maintenance and care
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 t he brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a se rious problem.
