CAUTION
■Road accident cautions
If your vehicle is involved in an accident, observe the following precautions
to reduce the risk of death or serious injury:
● Stop the vehicle in a safe place to prevent subsequent accidents.
While depressing the brake pedal, apply the parking brake and shift the
shift position to P to stop the hybrid system. Then, slowly release the
brake pedal.
● 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 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. This may
cause an electricity leakage leading to a fire. ( P. 437)
● 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.
■ Hybrid battery (traction battery)
Your vehicle contains a sealed nicke l-metal hydride battery. If disposed of
improperly, it is hazardous to the environment and there is a risk of severe
burns and electrical shock that may result in death or serious injury.

Hybrid vehicle driving tips
For economical and ecological driving, pay attention to the following
points:
■ Using Eco drive mode
When using Eco drive mode, the torque corresponding to the
accelerator pedal depression amount can be generated more
smoothly than it is in normal conditions. In addition, the opera-
tion of the air conditioning system (heating/cooling) will be mini-
mized, improving th e fuel economy. (P. 187)
■ Use of Hybrid System Indicator
Eco-friendly driving is possible by keeping the indicate of Hybrid
System Indicator within Eco area. ( P. 203)
■ When braking the vehicle
Make sure to operate the brakes gently and in good time. A
greater amount of electrical energy can be retained when slow-
ing down.
■ Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to bad fuel consumption. Check traffic
reports before leaving and avoid delays as much as possible.
When encountering a delay, gently release the brake pedal to
allow the vehicle to move forward slightly while avoiding overuse
of the accelerator pedal. Doing so can help control excessive
gasoline consumption.
■ Highway driving
Control your speed and keep at a constant speed. Also, before
stopping at a toll booth or similar, allow plenty of time to release
the accelerator and gently apply the brakes. A greater amount of
electrical energy can be reta ined when slowing down.

■
Air conditioning on/off
Switch the air conditioning ( ) to off when it is not needed.
Doing so can help control excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode.
Doing so will help to reduce t he burden on the air conditioner
and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut
out until the gasoline engine and the interior of the vehicle are
warm, it will consume fuel. Also, fuel consumption can be
improved by avoiding overuse of the heater.
■ Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently.
Improper tire inflation pressure can cause poor fuel consump-
tion.
Also, as snow tires can cause lar ge amounts of friction, their use
on dry roads can lead to poor fuel consumption. Use a tire that is
appropriate for the season.
■ Luggage
Carrying heavy luggage can lead to poor fuel consumption.
Avoid carrying unnecessary luggage. Installing a large roof rack
can also cause poor fuel consumption.
■ Warming up before driving
Since the gasoline engine starts up and cuts out automatically
when cold, warming up the engine is unnecessary. Moreover,
frequently driving s hort distances will ca use the engine to
repeatedly warm up, which can lead to poor fuel consumption.
