Parts and tools
Here is a list of parts and tools you will
need to perform do−it−yourself mainte-
nance. Remember all Toyota parts are de-
signed in metric sizes, so your tools must
be metric.
CHECKING THE ENGINE OIL LEVEL
Parts (if level is low):
Engine oil API grade SL “Energy −Con-
serving” or ILSAC multigrade having
viscosity proper for your climate
Tools:
Rag or paper towel
Funnel (only for adding oil)
CHECKING THE COOLANT LEVEL
Parts (if level is low):
“Toyota Super Long Life Coolant” or
similar high quality ethylene glycol
based non− silicate, non −amine, non− ni-
trite, and non −borate coolant with long −
life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a
mixture of 50% coolant and 50% deion-
ized water (for the U.S.A.) or 55%
coolant and 45% deionized water (for
Canada).
Tools:
Funnel (only for adding coolant) CHECKING BRAKE FLUID
Parts (if level is low):
SAE J1703 or FMVSS No.116 DOT 3
brake fluid
Tools:
Rag or paper towel
Funnel (only for adding fluid)
CHECKING AUXILIARY BATTERY CON-
DITION
Tools:
Warm water
Baking soda
Grease
Conventional wrench (for terminal
clamp bolts)
CHECKING AND REPLACING FUSES
Parts (if replacement is necessary):
Fuse with same amperage rating as
original
ADDING WASHER FLUID
Parts:
Water
Washer fluid containing antifreeze (for
winter use) Tools:
Funnel
REPLACING LIGHT BULBS
Parts:
Bulb with same number and wattage
rating as original (See charts in “Re-
placing light bulbs–” on page 302.)
Tools:
Screwdriver

During recharging, the battery is pro-
ducing hydrogen gas.
Therefore, before recharging:1. If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
2. Make sure the power switch on the recharger is off when connecting the
charger cables to the battery and when
disconnecting them.
CAUTION
Always charge the battery in an un-
confined area. Do not charge the
battery in a garage or closed room
where there is not sufficient ventila-
tion.
Only do a slow charge (3.5A or
less). Charging at a quicker rate is
dangerous. The battery may ex-
plode, causing personal injuries.
NOTICE
Never recharge the battery with the
hybrid system on. Also, be sure all
accessories are turned off.

If the headlights or other electrical
components do not work, check the
fuses. If any of the fuses are blown,
they must be replaced.
See “Fuse locations” on page 275 for
locations of the fuses.
Turn the hybrid system and inoperative
component off. Pull the suspected fuse
straight out and check it.
Determine which fuse may be causing the
problem. The lid of the fuse box shows
the name of the circuit for each fuse. See
page 314 for the functions controlled by
each circuit.Type A fuses can be pulled out by the
pull
−out tool. The location of the pull −out
tool is shown in the illustration.
If you are not sure whether the fuse has
blown, try replacing the suspected fuse
with one that you know is good.
If the fuse has blown, push a new fuse
into the clip.
Only install a fuse with the amperage rat-
ing designated on the fuse box lid.
If you do not have a spare fuse, in an
emergency you can pull out the “DOME”
or “OBD II” fuse, which may be dispens-
able for normal driving, and use it if its
amperage rating is the same.
If you cannot use one of the same amper-
age, use one that is lower, but as close
to the rating as possible. If the amperage
is lower than that specified, the fuse
might blow out again. but this does not
indicate anything wrong. Be sure to get
the correct fuse as soon as possible and
return the substitute to its original clip.
It is a good idea to purchase a set of
spare fuses and keep them in your ve-
hicle for emergencies. If the new fuse immediately blows out,
there is a problem with the electrical sys-
tem. Have your Toyota dealer correct it as
soon as possible.
CAUTION
Never use a fuse with a higher am-
perage rating, or any other object, in
place of a fuse. This may cause ex-
tensive damage and possibly a fire.
