voltage battery.
WARNING
Never disconnect the high voltage
cut-off switch except in an emergency
situation.
Serious problems may occur, such as

NOTICE
• Ambient temperature affects the tire pressure (about 7kPa (1 psi) for every
12°F (7°C) change). If colder temperatures are anticipated, it is permissible to
increase cold tire inflation pressure by up to 20 kPa (3 psi) over the specification.
If extreme temperature changes are expected, be sure to check and adjust tire
pressure accordingly.
• Tire inflation pressure decreases with higher elevation, and increases with lower
elevation (about 10 kPa (2.4 psi) for every mile (or kilometer) elevation change).
Be sure to check and adjust tire pressure accordingly when driving through
changing elevations.
• Do not exceed the maximum inflation pressure, as found on the sidewall of the
tire(s).
CAUTION
When replacing tires, ALWAYS use the same size, type, brand, construction and
tread pattern supplied with the vehicle. If not, it can damage the related parts or
make it work irregularly.

Seats & Safety System
3-8
CAUTION
To prevent injury: • Do not adjust your seat while
wearing your seat belt. Moving the
seat cushion forward may cause
strong pressure on your abdomen.
• Do not allow your hands or fingers to
get caught in the seat mechanisms
while the seat is moving.
WARNING
NEVER allow children in the vehicle
unattended. The power seats are
operable when the vehicle is turned off.
NOTICE
To prevent damage to the seats: • Always stop adjusting the seats when
the seat has been adjusted as far
forward or rearward as possible.
• Do not adjust the seats longer than
necessary when the vehicle is turned
off. This may result in unnecessary
battery drain.
• Do not operate two or more seats at
the same time. This may result in an electrical malfunction. Manual adjustment (if equipped)
The front seat can be adjusted by using
the levers located underneath the seat
cushion. Before driving, adjust the seat
to the proper position so that you can
easily control the steering wheel, foot
pedals and controls on the instrument panel.ONE1031003N
Forward and rearward adjustment
To move the seat forward or rearward:
1. Pull up the seat slide adjustment lever
and hold it.
2. Slide the seat to the position you desire.
3. Release the lever and make sure the seat is locked in place. Move forward
and rearward without using the lever.
If the seat moves, it is not locked
properly.

Seat Warmers
Seat warmers are provided to warm the
seats during cold weather.
During mild weather or under conditions
where the operation of the seat warmer
is not needed, keep the seat warmers
OFF.
WARNING
The seat warmers can cause a SERIOUS
BURN, even at low temperatures and
especially if used for long periods of time.
Passengers must be able to feel if the
seat is becoming too warm so they can
turn it off, if needed.
Seat warmer consume large amounts
of electricity. Please avoid using seat
warmers while the vehicle is off in order
to prevent battery discharge.
People who cannot detect temperature
change or pain to the skin should
use extreme caution, especially the
following types of passengers: • Infants, children, elderly or disabled
persons, or hospital outpatients.
• People with sensitive skin or who
burn easily.
• Fatigued individuals.
• Intoxicated individuals.
• People taking medication that can
cause drowsiness or sleepiness.
WARNING
NEVER place anything on the seat
that insulates against heat when the
seat warmer is in operation, such as a
blanket or seat cushion. This may cause
the seat warmer to overheat, causing a
burn or damage to the seat.
NOTICE
To prevent damage to the seat warmers
and seats: • Never use a solvent such as paint
thinner, benzene, alcohol or gasoline
to clean the seats.
• Do not place heavy or sharp objects
on seats equipped with seat
warmers.
• Do not change the seat cover. It may
damage the seat warmer.

Power/Charge Gauge
ONE1Q011050
The Power/Charge Gauge shows the
energy consumption rate of the vehicle
and the charge/discharge status of the
regenerative brakes. • POWER :
It shows the energy consumption rate
of the vehicle when driving uphill or
accelerating. The more electric energy
is used, the higher the gauge level.
• CHARGE :
It shows the charging status of the
battery when it is being charged by
the regenerative brakes (decelerating
or driving on a downhill road). The
more electric energy is charged, the
lower the gauge level.
State of Charge (SOC) Gauge for
High Voltage Battery
ONE1Q011003
• The SOC gauge shows the charging
status of the high voltage battery.
• The low percentage number on the
indicator indicates that there is not
enough energy in the high voltage
battery. 100% indicates that the
driving battery is fully charged.
• When driving on highways or
motorways, make sure to check
in advance if the driving battery is
charged enough.
