76GAUGES, METERS AND SERVICE REMINDER INDICATORS
While driving on steep inclines or rough
roads which causes the vehicle to sub-
stantially sway or on curves, this light
may come on due to the movement of
engine oil in the engine.
In normal conditions, due to engine oil
consumption, this light may come on earli-
er than the specified service interval of
the scheduled maintenance. This is be-
cause the engine oil is consumed to the
low level within the scheduled mainte-
nance interval and does not indicate a
problem. (For detailed information, see
“Facts about engine oil consumption” on
page 123 in Section 2.)
NOTICE
Continued engine operation with low
engine oil will damage the engine.
(e) Malfunction Indicator Lamp
This lamp comes on in the following
cases.
a. On some models: The fuel tank is
completely empty. (See “Fuel gauge”
on page 68 in this Section for instruc-
tions.)

gine control system orengine emission
control system.
If it comes on while you are driving in
case b, have your vehicle checked/re-
paired by any authorized Toyota dealer or
repairer, or another duly qualified and
equipped professional, as soon as pos-
sible.If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic engine controlsystem. Stop the ve-
hicle and contact any authorized Toyota
dealer or repairer, or another duly quali-
fied and equipped professional, or take
your vehicle carefully, since the vehicle
performance will be lower than normal, to
any authorized Toyota dealer or repairer,
or another duly qualified and equipped
professional, as soon as possible.
Even if the abnormality in the electronic
engine controlsystem is corrected during
low speed driving, thesystem may not
recover until the engine is stopped and
the engine switch is turned to the “ACC”
or “LOCK” position.
The lamp flashes when the engine emis-
sion control system is not functioning cor-
rectly. If the engine is run for more than
50 hours with the lamp flashing, the sys-
tem will automatically reduce engine per-
formance until the malfunction is cor-
rected.
(f) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.

INFORMATION BEFORE DRIVING YOUR TOYOTA121
NOTICE
To prevent damage to the system and
a fire hazard, observe the following
precautions:
zUse only diesel fuel.
zDo not drive for long periods of
time while the DPF system indicator
light is flashing.
zDo not use fuel other than the spe-
cified type.
zDo not use engine oil other than
the recommended type.
zDo not modify the exhaust pipe.
zOperating the vehicle when the en-
gine oil contains a significant
amount of diesel fuel may result in
damage to the engine. If a signifi-
cant amount of fuel is present,
change the oil as soon as possible.
zDo not drive with an extremely low
fuel level; running out of fuel could
cause the engine to misfire, creat-
ing an excessive load on the cata-
lytic converter.
zDo not pull−or push−start your ve-
hicle.
zDo not turn off the engine switch
while the vehicle is moving.
zKeep your engine switch in good
running order. Malfunctions in the
engine electrical system or fuel sys-
tem could cause an extremely high
catalytic converter temperature.
zIf the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a check−up to any
authorized Toyota dealer or repairer,
or another duly qualified and
equipped professional.
zTo ensure that the catalytic convert-
er and the entire emission control
system operate properly, your ve-
hicle must receive the periodic in-
spections required by the Toyota
Maintenance Schedule. For sched-
uled maintenance information, refer
to the “Toyota Service Booklet” or
“Toyota Warranty Booklet”.

124INFORMATION BEFORE DRIVING YOUR TOYOTA
The tandem master cylinder brakesystem
is a hydraulic system with two separate
sub−systems. If either sub−system should
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will increase. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
power−assist the brakes. If the engine
should quit while you are driving, you can
bringthevehicletoastopwithnormal
pedal pressure. There is enough reserved
vacuum for one or two stops—but no
more!
CAUTION
DDo not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your reserved vacu-
um.
DEven if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard, much harder than nor-
mal. And your braking distance will
increase.
ANTI−LOCK BRAKE SYSTEM
(with “ABS” warning light)
The anti−lock brake system is designed
to help prevent lock−up of the wheels
during a sudden braking or braking on
slippery road surfaces. This assists in
providing directional stability and steer-
ing performance of the vehicle under
these circumstances.
Effective way to press the ABS brake
pedal:
When the anti−lock brake system func-
tion is in action, you may feel the brake
pedal pulsating and hear a noise. In this
situation, to let the anti−lock brake sys-
tem work for you, just hold the brake
pedal down more firmly. Do not pump
the brake in a panic stop. This will re-
sult in reduced braking performance.
The anti−lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).
Depressing the brake pedal on slippery
road surfaces such as on a manhole cov-
er, a steel plate at a construction site,
joints in a bridge, etc. on a rainy day
tends to activate the anti−lock brake sys-
tem.
You may hear a click or motor sound from
the area around the front axle for a few
seconds when the engine is started or just
after the vehicle begins to move. This
means that the anti−lock brake system is
in the self−check mode, and does not indi-
cate a malfunction.
