2012 TOYOTA DYNA 100/150 check engine light

200DO−IT−YOURSELF MAINTENANCE: Engine and Chassis
If any of the above parts are extremely
dirty or you are not sure of their condi-
tion, take your vehicle to any authorized
Toyota dealer or repairer, or another duly
qualified and equipped professional.
CAUTION
To prevent burning yourself, be care-
ful not to touch the radiator, con-
denser and intercooler when the en-
gine is hot.
NOTICE
To prevent damage to the radiator,
condenser and intercooler, do not per-
formtheworkbyyourself.
When the fuel filter warning light
comes on, the water in the fuel filter
must be drained immediately.
Place a small tray under the drain plug to
catch the water.
1. Turn the drain plug about 2—2−1/2
turns, as shown above. (Loosening
more than this will cause water oozing
from around the drain plug.)
2. Operate the priming pump until fuel be-
gins to run out.
After draining, retighten the drain plug. Do
not use a tool.

CAUTION
BATTERY PRECAUTIONS
The battery produces flammable and
explosive hydrogen gas.
DDo not cause a spark from the bat-
tery with tools.
DDo not smoke or light a match near
the battery.
The electrolyte contains poisonous
and corrosive sulfuric acid.
DAvoid contact with eyes, skin or
clothes.
DNever ingest electrolyte.
DWear protective safety glasses when
working near the battery.
DKeep children away from the bat-
tery.
EMERGENCY MEASURES
DIf electrolyte gets in your eyes,
flush your eyes with clean water
immediately and get immediate
medical attention. If possible, con-
tinue to apply water with a sponge
or cloth while en route to the medi-
cal office.
DIf electrolyte gets on your skin,
thoroughly wash the contact area. If
you feel pain or burning, get medi-
cal attention immediately.
DIf electrolyte gets on your clothes,
there is a possibility of its soaking
through to your skin, so immediate-
ly take off the exposed clothing and
follow the procedure above, if nec-
essary.
DIf you accidentally swallow electro-
lyte, drink a large quantity of water
or milk. Get emergency medical
attention immediately.
The electricity stored in the battery will
discharge gradually even when the vehicle
is not in use, due to natural discharge
and the draining effects of certain electri-
cal appliances. If the vehicle is left for a
long time, the battery may discharge, and
the engine may be unable to start. (The
battery recharges automatically during
driving.)

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 190 in Sec-
tion 7−1 for locations of the fuses.
Turn the engine switch 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 227 in Section 8 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 “CIG”,
“DOME” or “A/C” fuse, which may be dis-
pensable for normal driving, and use it if
its amperage rating is the same.
