If You Cannot Increase Engine Speed; If Your Vehicle Overheats - Toyota Coaster 2015 Owner's Manual

If you cannot increase engine
speed
If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic engine control system. Stop the ve-
hicle and contact your Toyota dealer or
take your vehicle carefully, since the ve-
hicle performance will be lower than nor-
mal, to your Toyota dealer as soon as
possible.
Even if the abnormality in the electronic
engine control system is corrected during
low speed driving, the system may not
recover until the engine is stopped and
the engine switch is turned to the "ACC"
or "LOCK" position.

If your vehicle overheats

If your engine coolant
gauge indicates over heating, if you ex-
perience a loss of power, or if you hear
a loud knocking or pinging noise, the
engine has probably overheated. You
should follow this procedure...
1. Pull safely off the road, stop the ve-
hicle and turn on your emergency
flashers. Put the transmission in "P"
(automatic) or neutral (manual) and ap-
ply the parking brake. Turn off the
cooler if it is being used.
2. If coolant or steam is boiling out of the
radiator or reservoir, stop the engine.
Wait until the steam subsides before
opening the engine access hole cover.
If there is no coolant boiling over or
steam, leave the engine running.
CAUTION
To help avoid personal injury, keep
the engine access hole cover closed
until there is no steam. Escaping
steam or coolant is a sign of very
high pressure.
temperature 3. Visually check to see if the engine
drive belt (fan belt) is broken or loose.
Look for obvious coolant leaks from the
radiator, hoses, and under the vehicle.
However, note that water draining from
the cooler is normal if it has been
used.
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.
4. If the engine drive belt is broken or the
coolant is leaking, stop the engine im-
mediately. Call a Toyota dealer for as-
sistance.
5. If the engine drive belt is O.K. and
there are no obvious leaks, you may
help the engine cool down more quickly
by running it at about 1500 rpm for a
few minutes with the accelerator pedal
lightly depressed.
6. Check the coolant reservoir. If it is dry,
add coolant to the reservoir while the
engine is running. Fill it about half full.
For the coolant type, see "Coolant type
selection" in Section 7−2.
