For safety and security
CAUTION
■High voltage precautions
The vehicle has high voltage DC and AC systems as well as a 12-volt system. DC
and AC high voltage is very dangerous and can cause severe burns and electric
shock that may result in death or serious injury.
●Never touch, disassemble, remove or re place the high voltage parts, cables or
their connectors.
●The hybrid system will become hot after starting as the system uses high voltage.
Be careful of both the high voltage and the high temperature, and always obey
the caution labels attached to the vehicle.
■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 flui d 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 imme diate 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
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. 7 0 4 )
●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.
●Never try to open the service plug access
hole located behind the rear seats. The ser-
vice plug is used only when the vehicle is
serviced and is subject to high voltage.

●When all of the following conditions are satisfied and Eco-friendly driving, ECO
lamp (blue) will illuminate. (ECO lamp will become brighter the more Eco-friendly
driving you perform. Also, while the vehicle is stopped or the acceleration exceeds
Zone of Eco driving, ECO lamp turns off. (P. 9 2 ) H o w e v e r, w h e n E c o d r i v e
mode is selected, while the vehicle is stopped or the acceleration exceeds Zone of
Eco driving, ECO lamp does not turn off.):
• Driving with the shift lever in D
• Paddle shift switch is not operated.
• Either normal mode or Eco drive mode is selected.
• The vehicle speed is approximately 80 mph (130 km/h) or below.
■Tachometer
Hybrid System Indicator switches to the ta chometer when driving mode is in sport
mode.
■Engine speed
On hybrid vehicles, engine speed is precis ely controlled in order to help improve
fuel efficiency and reduce exhaust emissions etc.
There are times when the engine speed that is displayed may differ even when vehi-
cle operation and driving conditions are the same.
■Customization
Settings (e.g. on/off operatio n of ECO lamp) can be changed.
(Customizable features P. 8 0 7 )
