charging TOYOTA TUNDRA 2002 1.G Owners Manual

’02 TUNDRA_U (L/O 0108)
902002 MY TUNDRA_U (OM 34417U)
NOTICE
Do not drive the vehicle with the oil
pressure below the normal range until
the cause is fixed—it may ruin the
engine.
The voltmeter tells whether the battery
is charged or discharged. Check it
while the engine is running—the needle
should always indicate as shown above.
If the needle reads below or above the
normal range while the engine is running,
it indicates the charging system needs im-
mediate repair.
However, it is normal for the needle to
drop below the normal range during en-
gine starting.The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and overrevving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.

CAUTION
If the light does not turn off even
after the parking brake is released
while the engine is running, immedi-
ately stop your vehicle at a safe
place and contact your Toyota dealer.
In this case, the brakes may not work
properly and your stopping distance
will become longer. Depress the brake
pedal firmly and bring the vehicle to
an immediate stop.
(b) Driver’s Seat Belt Reminder Light
and Buzzer
This light and buzzer remind you to
buckle up the driver’s seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes and
buzzer sounds if the driver ’s seat belt is
not fastened. Unless the driver fastens the
belt, the light keeps flashing and the
buzzer stops after about 4 to 8 seconds. (c) Front Passenger ’s Seat Belt Re-
minder Light
This light reminds you to buckle up the
front passenger ’s seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes if a
passenger sits in the front passenger seat
and does not fasten the seat belt. Howev-
er, if a front passenger uses an additional
seat cushion, the light may not flash even
when the seat belt is not buckled up.
If luggage load is placed on the front
passenger seat, depending on its weight
and how it is placed on the seat, builtin
sensors in the seat cushion may detect
the pressure, causing the reminder light to
keep flashing.
(d) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.
NOTICE
Do not continue driving if the engine
drive belt is broken or loose.
(e) Low Engine Oil Pressure Warning Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Toyota dealer or qualified repair shop for
assistance.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.

Do not connect the cable to or near
any part that moves when the engine
is cranked.
CAUTION
When making the connections, to
avoid serious injury, do not lean over
the battery or accidentally let the
jumper cables or clamps touch any-
thing except the correct battery termi-
nals or the ground.
5. Start your engine in the normal way.
After starting, run it at about 2000 rpm
for several minutes with the accelerator
pedal lightly depressed.
6. Carefully disconnect the cables in the exact reverse order: the negative cable
and then the positive cable.
7. Carefully dispose of the battery cover cloths—they may now contain sulfuric
acid.
8. If removed, replace all the battery vent plugs.
If the cause of your battery discharging is
not apparent (for example, lights left on),
you should have it checked. If your engine stalls while driving...
1. Reduce your speed gradually, keeping a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see “If your
vehicle will not start”.
CAUTION
If the engine is not running, the pow-
er assist for the brakes and steering
will not work, so steering and braking
will be much harder than usual.
If your engine coolant temperature
gauge indicates overheating, 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 air
conditioning 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 hood. If there is no coolant
boiling over or steam, leave the engine
running.
CAUTION
To help avoid personal injury, keep
the hood closed until there is no
steam. Escaping steam or coolant is
a sign of very high pressure.

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. Be sure the power switch on the re- charger 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 (5 A or
less). Charging at a quicker rate is
dangerous. The battery may ex-
plode, causing personal injuries.
NOTICE
Never recharge the battery while the
engine is running. Also, be sure all
accessories are turned off.
