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.
●Short in electrical components
● Traction battery damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following.
● Brake function
● Changes in quantity and quality of transmission fluid and so forth.
● Lubricant condition for the bearings and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.
● If the P position control system is damaged by flooding, it may not be pos-
sible to shift the shift position to P, or from P to other positions. When the
shift position cannot be changed from P to any other position, the front
wheels will lock, and moving the vehicle with the front wheels on the
ground will not be possible. In this case, move the vehicle with both front
wheels or all four wheels lifted.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
■ Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Motor coolant
• Heater coolant
• Traction battery coolant
• Washer fluid
● Have a service technician inspec t the condition of the 12-volt
battery.
● 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.
■Before driving the vehicle
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.
● Do not try to forcibly open the charging port cap if it is frozen.
Melt the ice using a hair dryer, immediately and thoroughly
wiping away any moisture.
● To ensure proper operation of th e 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
accumulated on the exterior li ghts, vehicle's roof, chassis,
around the tires or on the brakes.

Do-it-yourself ser vice precautions
If you perform maintenance yourself, be sure to follow the correct
procedures as given in these sections.
ItemsParts and tools
12-volt battery condition( P. 362) • Grease
• Conventional wrench
(for terminal clamp bolts)
Brake fluid level ( P. 361)• FMVSS No.116 DOT 3 or SAE
J1703 brake fluid
• Rag or paper towel
• Funnel (used only for adding brake fluid)
Motor coolant level ( P. 357)• “Zerex G 48” or “Glysantin G 48”
only
The dilution ratio for both “Zerex
G 48” and “Glysantin G 48” is
50% coolant and 50% deionized
water.
• Funnel (used only for adding motor coolant)
Traction battery coolant level (P. 357) 
(Contact your Toyota dealer if the
level is on or below the “L” line.
The reservoir cap is not intended
to be opened by the user.
Improper filling can lead to trac-
tion battery system damage. Only
qualified personnel should service
the traction battery coolant.)

348 4-3. Do-it-yourself maintenance
CAUTION
The motor 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 motor compartment
●Make sure that the indicator on the “POWER” switch and the “READY”
indicator are both off.
● Keep hands, clothing and tools away from the moving fans.
● Be careful not to touch the motor, power control unit, radiator, heater, etc.
right after driving as they may be hot. Coolant and other fluids may also be
hot.
● Do not leave anything that may burn easily, such as paper and rags, in the
motor compartment.
● Do not smoke, cause sparks or expose an open flame to the 12-volt bat-
tery. 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 experience discomfort, see a doctor.
● Never touch, disassemble, remove or replace the high voltage parts,
cables and their connectors. It can cause severe burns or electric shock
that may result in death or serious injury.
■ When working near the electric c ooling fans or radiator grille
Be sure the “POWER” switch is off.
With the “POWER” switch in ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. ( P. 360)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

Maintenance and care
Brake fluid
■ Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN”
lines on the tank.
■ Adding fluid
Make sure to check the fluid type and prepare the necessary items.
Fluid type SAE J1703 or FMVSS No.116 DOT 3 brake fluid
Items Clean funnel
■ Brake fluid can absorb moisture from the air
Excess moisture in the brake fluid can cause a dangerous loss of braking
efficiency. Use only newly opened brake fluid.
CAUTION
■When filling the reservoir
Take care as brake fluid can harm your hands and 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 discomfort, see a doctor.

362 4-3. Do-it-yourself maintenance
12-volt batteryCheck the 12-volt battery as follows:
■ 12-volt battery exterior
Make sure that the 12-volt battery terminals are not corroded and
that there are no loose connecti ons, cracks, or loose clamps.
Te r m i n a l s
Hold-down clamp
NOTICE
■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 refilling, there may be a serious proble\
m.
■Before recharging the 12-volt battery
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, observe the following precautions before
recharging:
●If recharging with the 12-volt battery installed on the vehicle, be sure to
disconnect the ground cable.
● Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the 12-volt battery.
