sidewall.
Maximum Load Rating
The load rating for a tire at the maxi-
mum permissible inflation pressure
for that tire.
Maximum Loaded VehicleWeight
The sum of curb weight; accessory
weight; vehicle capacity weight; and
production options weight.
Normal Occupant Weight
The number of occupants a vehicle
is designed to seat multiplied by 150
pounds (68 kg).
Occupant Distribution
Designated seating positions.
Outward Facing Sidewall
An asymmetrical tire has a particular
side that faces outward when mount-

When a vehicle accident
occurs, move the vehicle to a
safe place, turn OFF the vehi-
cle and remove the auxiliary
battery (12 V) terminal to pre-
vent high voltage electricity
from flowing.
If electric wires are exposed
from inside or outside the
vehicle, do not touch the
wires.
Also, do not touch the high
voltage electric wire (orange),
connector, and all electric
components and devices. This
may cause electric shock and
lead to injuries.
WARNING When a vehicle accident
occurs and the high voltage
battery is damaged, harmful
gas and electrolytes may leak.
Be careful not to touch the
leaked liquid.
When you suspect leakage of
inflammable gas and other
harmful gases, open the win-
dows and evacuate to a safe
place. If any leaked fluid
comes in contact with your
eyes or skin, immediately
clean the affected area thor-
oughly with tap water or
saline solution and have doc-
tors inspect it as soon as pos-
sible.
WARNING
If a small scale fire occurs,
use a fire extinguisher (ABC,
BC) that is meant for electrical
fires. If it is impossible to
extinguish the fire in the early
stage, remain a safe distance
from the vehicle and immedi-
ately call 911. Also, advise
them that an electric vehicle is
involved.
If the fire spreads to the high
voltage battery, large amount
of water is needed to put out
the fire. Using small amount
of water or fire extinguishers
not meant for electrical fires
could cause serious injury or
death from electrical shocks.
