2005 HIGHLANDER from Nov. '04 Prod. (OM48570U)

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.

drive belt is broken or loose.

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 onÐeven for one block.
It may ruin the engine.
(f) Malfunction Indicator Lamp
This lamp comes on when the ignition
key is turned to the ONº position and
goes off after the engine starts. This
means that the warning light system is
operating properly.
If the lamp remains on, or the lamp
comes on while driving, first check the
followings.
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
Loose fuel tank cap
If the fuel tank cap is loose, securely
tighten it.
These cases are temporary malfunctions.
The malfunction indicator lamp will go off
after taking several driving trips.
If the lamp does not go off even after
several trips, contact your Toyota dealer
as soon as possible.If the fuel tank is not empty or the fuel
tank cap is not loose...
There is a problem somewhere in the
engine, emission control system, elec-
tronic throttle control system, automatic
transmission electrical system or warn-
ing light system itself.
In this case, slow down and have your
vehicle checked/repaired by your Toyota
dealer as soon as possible.
If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle
checked by your Toyota dealer as soon as
possible.
Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the ignition key is turned to ACCº or
LOCKº position.

CAUTION

neous pedal operation.
Emissions Inspection and Maintenance
(I/M) programs
Your vehicle may not pass a state
emission inspection if the malfunction
indicator lamp remains on. Contact your
Toyota dealer to check your vehicle's
emission control system and OBD
(On- Board Diagnostics) system before
taking your vehicle for the inspection.
For details, see Emissions Inspection and
Maintenance (I/M) programsº on page 370
in Section 6.
(g) 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.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.(h) ABSº Warning Light
The light comes on when the ignition key
is turned to the ONº position. If the anti-
lock brake system and the brake assist
system work properly, the light turns off
after a few seconds. Thereafter, if the
system malfunctions, the light comes on
again.
When the ABSº warning light is on (and
the brake system warning light is off), the
anti- lock brake system, the brake assist
system, the traction control system and
the vehicle stability control system do not
operate, but the brake system still oper-
ates conventionally.
When the ABSº warning light is on (and
the brake system warning light is off), the
anti- lock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.If either of the following conditions
occurs, this indicates a malfunction
somewhere in the components moni-
tored by the warning light system. Con-
tact your Toyota dealer as soon as
possible to service the vehicle.The light does not come on when the
ignition key is turned to the ONº posi-
tion, or remains on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the ABSº warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the anti- lock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.

tion key is turned to the ONº position.

cator light, AIRBAG OFFº indicator light,
front passenger 's seat belt buckle switch,

ors, warning light, interconnecting wiring
and power sources.

ignition key is turned to the ONº posi-
tion or remains on for more than 6

(m) Low Tire Pressure Warning Light
This light warns that the tire inflation pres-
sure is critically low. The light comes on
when the ignition key is turned to the
ONº position. It goes off after a few sec-
onds. This indicates that the low tire pres-
sure warning system is functioning proper-
ly.
If the light comes on while driving, adjust
tire inflation pressure to the specified lev-
el. (See Tiresº on page 410 in Section 8.)
After the tire inflation pressure is adjusted,
push the tire pressure warning system re-
set switch for a few seconds and make
sure the warning light goes off. If the light
still remains or blinks once every second,
have the low tire pressure warning system
checked at your Toyota dealer.
If the light blinks twice every second, the
low tire pressure warning system needs to
be initialized.

systemº on page 161 in Section 1- 7.(n) Low Windshield Washer Fluid Level
Warning Light

Light (for vehicles sold in U.S.A.)
This light acts as a reminder to replace
the engine oil.
This light will come on when the ignition
key is turned to ONº and will go off after
about a few seconds.
When you drive for about 7200 km (4500
miles) after the engine oil replacement,
this light illuminates for about 3 seconds
and then flashes for about 12 seconds
with the ignition key turned to the ONº
position. If you continue driving without
replacing the engine oil, and if the dis-
tance driven exceeds 8000 km (5000
miles), the light will come on after the
ignition key is turned to ONº position.
The light will remain on thereafter.
If the light is flashing, we recommend that
you replace the engine oil at an early
opportunity depending on the driving and
road conditions. If the light comes on,
replace it as soon as possible.The system must be reset after the en-
gine oil replacement. Reset the system by
the following procedure:
1. Turn the ignition key to the LOCKº
position with the odometer reading
shown. (For details, see Odometer and
two trip metersº on page 133 in this
Section.)
2. Turn the ignition key to the ONº posi-
tion while holding down the trip meter
reset knob.
Hold down the knob for at least 5 sec-
onds. The odometer indicates 000000º
and the light goes off.
If the system fails to reset, the light will
continue flashing.

the key when you open the driver's door
with the ignition key in the ACCº or
LOCKº position.
