For safety and security
HIGHLANDER_HV_U (OM48F12U)
WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death or serious
injury:
● Pull your vehicle off the road, shift the shift lever to P, apply the parking
brake, and turn the hybrid system off.
● Do not touch the high voltage parts, cables or connectors.
● If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
● If a fluid leak occurs, do not touch the fluid as it may be strong alkaline
electrolyte from the hybrid battery (traction battery). If it comes into contact
with your skin or eyes, wash it off immediately with a large amount of water
or, if possible, boric acid solution. Seek immediate medical attention.
● If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible.
Never use a fire extinguisher that is not meant for electric fires. Using even
a small amount of water may be dangerous.
● If your vehicle needs to be towed, do so with all four 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. This may
cause a fire. (
→P. 562)
● 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.

1944-1. Before driving
HIGHLANDER_HV_U (OM48F12U)■
Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type par king brake system. This type of brake
system needs bedding-down of the brake shoes periodically or whenever the
parking brake shoes and/or drum are replaced. Have your Toyota dealer per-
form the bedding down operation.
■ Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. ( →P. 641)
■ Brake actuator
The brake actuator uses brake fluid pressurized by the pump to power-assist
the brakes. If the brake actuator fails during driving, the brake system warn-
ing light comes on and the buzzer sounds intermittently. In this case, the
brakes may not work properly. If they do not work well, depress the brake
pedal firmly. If the brake system warning light comes on, immediately stop
your vehicle and contact your Toyota dealer.
In the following conditions, you may hear a sound in the engine compartment.
This is not a malfunction.
● The driver’s door is opened with the hybrid system turned off.
● The brake pedal is depressed with the hybrid system turned off.
● After the hybrid system is turned on.
● The brake pedal is depressed repeatedly with the hybrid system turned on.
● After the hybrid system is turned off.
The brake pedal may be hard to depress or the brake pedal stroke may be
short before turning the hybrid system on. This is not a malfunction.
■ When braking the vehicle
When applying brakes, you may hear a sound coming from the motor gener-
ator.
However, this does not indicate any trouble.

NOTICE
■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.
■ 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, underside of the vehicle, etc.
■ If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
● It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds or vibrations.
● The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( →P. 597)
■ When encounterin g 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 your Toyota dealer check the following:
● Brake function
● Changes in quantity and quality of oil and fluid used for the engine, hybrid
transmission, rear electric motor (traction motor), etc.
● Lubricant condition for the bearings and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.
