ts including high-
voltage wires colore
d orange and their
connectors. Doing so can result in a fire, property damage, elec
trocution and seri-
ous injury or death. These components are affixed with a label indicating precautions for handling. Fol-low the instructions on the label. Take your vehicle to a cert
ified i-MiEV dealer
for any necessary maintenance.

WA R N I N G When servicing the vehicle, make sure that the electric motor switch is in the“LOCK” position and
the charging cable
is disconnected. Failure to do so could result in an electric shock.
When checking or servicing under the hood or the coolant reserve tank, be surethe electric motor unit is stopped and ithas had a chance to cool down. If you need to work
under the hood with
the electric motor unit on, be careful that your clothing, hair, etc. does not get caught in the fan or other moving parts. The fan can turn on automatically even if the electric motor unit is not running.Turn the electric motor switch to the “LOCK” position to be
safe while you are
working under the hood. Do not smoke or allow open flames around the 12V starter battery. Be extremely careful when working around the 12V starter battery. It containspoisonous and corros
ive sulfuric acid.
Handling your vehicle’s parts and materi- als in the wrong way can injure you. Ask a certified i-MiEV dealer
if you have ques-
tions. CAUTION The components inside
the electric motor
unit room may be very
hot to the touch.
Make sure all components have sufficientlycooled before beginning an inspection. These components are affixed with a label indicating precautions
for handling. Follow
the instructions on the label.WA R N I N G

It is important to familiarize yourself with the following terms: Cold tire pressure: • The measured pressure after the vehiclehas been parked for
at least three hours,
or • The measured pressure when the vehicleis driven less than 1 mile (1.6 km) after having been parked for three hours.
Maximum inflation pressure: the maxi- mum permissible cold
tire inflation pres-
sure for this tire. Recommended inflation pressure: the inflation pressure for optimum tire perfor- mance.
WA R N I N G Open doors and wind
ows in any closed
space where you may be charging orworking with the 12V starter battery. Always wear protective clothing and gog- gles when working wi
th the 12V starter
battery, or have a sk
illed automobile tech-
nician do it. If you are quick-charging your 12V starter battery, first disconnect the 12V starter battery cables. In order to prevent a short circuit, be sure to disconnect the negative (-) terminalfirst, and reconnect it last. If the electrolyte level
is very low, have the
12V starter battery checked at a certified i-MiEV dealer. 12V starter battery te
rminals and related
accessories contain
lead and lead com-
pounds. Wash hands after handling. CAUTION When replacing the
12V starter battery,
remove the connected
positive (+) and nega-
tive (-) terminals after turning the electric motor switch to the “LOCK” position andwaiting at least 1 minut
e. If the 12V starter
battery terminal is removed just after the electric motor switch is turned to the “LOCK” position, this
may cause damage to
components of the electric motor unit.
NOTE
Before cleaning the 12V starter battery, tighten all the filler port
caps to keep dirt and
moisture out. Check each 12V starter battery terminal for corrosion. If necessary, clean the terminalswith a solution of baking soda and water. Grease the posts and cl
amps after cleaning or
tightening them. Check to see that the 12V starter battery is securely installed and
cannot be moved. Also
check each terminal for tightness. If you will not be driv
ing your vehicle for a
long period of time, re
move the 12V starter
battery and store it in a place where the 12V starter battery fluid wi
ll not freeze. Memory
data for settings made by the user may be erased when the 12V starter battery is removed. If this happens, reset the settingsagain using the releva
nt procedures. The
12V starter battery
only should be stored
with a full charge.
Tires
WA R N I N G Driving with tires that are worn, damaged or improperly inflated is dangerous.These type tire conditions will adversely affect vehicle performance. These type tire conditions can also cause atread separation or blowout which may result in an accide
nt causing serious
injury or death. Tires degrade over ti
me with age even
when they are not being used. It is recom-mended that tires ove
r 6 years generally
be replaced even if
damage is not obvious.
