WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death or 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.
●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 rear wheels raised. If the wheels con-
nected 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. 454)
●Carefully inspect the ground under the vehicl e. If you find that liquid has leaked onto
the ground, the fuel system may have been damaged. Leave the vehicle as soon as possible.

parked on an incline.
●Depending on the vehicle usage conditions, the brake fluid pressure display may not
reach its maximum reading even though the brake pedal is fully depressed.
●If a 12-volt battery terminal is disconnected and reconnected, the steering amount dis-
play may be disabled temporarily. After driv ing the vehicle for a while, the display will
be enabled.
●Depending on the condition of the vehicle, the brake fluid pressure display may change
even when the brake pedal is not depressed.

■Tire inflation pressure (if equipped)
●It may take a few minutes to display the tire inflation pressure after the power switch is
turned to ON mode. It may also take a few minutes to display the tire inflation pressure
after inflation pressure has been adjusted.
●“---” may be displayed if the tire information cannot be determined due to unfavorable
radio wave conditions.
●Tire inflation pressure changes with temperature. The displayed values may also be dif-
ferent from the values measured using a tire pressure gauge.
■When disconnecting and reconnecting 12-volt battery terminals
The drive information will be reset.

■When starting off on a uphill
The hill-start assist control is available. ( P. 325)
■For fuel-efficient driving
Keep in mind that hybrid vehicles are similar to conventional vehicles, and it is necessary
to refrain from activities such as sudden acceleration, etc. Refer to “Hybrid vehicle driv-
ing tips”. ( P. 331)
■Driving in the rain
●Drive carefully when it is ra ining, because visibility will be reduced, the windows may
become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially slip-
pery.
●Refrain from high speeds when driving on an expressway in the rain, because there may
be a layer of water between the tires and the road surface, preventing the steering and
brakes from operating properly.
■Restraining hybrid system outp ut (Brake Override System)
●When the accelerator and brake pedals are depressed at the same time, the hybrid sys-
tem output may be restrained.
●A warning message is displayed on the mult i-information display while the system is
operating. ( P. 485)
■Restraining sudden start (Drive-Start Control)
●When the following unusual operation is pe rformed, the hybrid system output may be
restrained.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the “READY” indicator is
illuminated. This prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator ped-
als to avoid depressing the wrong pedal.
