(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.
For details, see Tire pressure warning
systemº on page 161 in Section 1- 7.(n) Low Windshield Washer Fluid Level
Warning Light
The light warns that the windshield washer
fluid level is too low. Add washer fluid at
your earliest opportunity. (For instructions,
see Adding washer fluidº on page 399 in
Section 7- 3.)
(o) Engine Oil Replacement Reminder
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.
(p) Key Reminder Buzzer
This buzzer acts as a reminder to remove
the key when you open the driver's door
with the ignition key in the ACCº or
LOCKº position.

LOW TIRE PRESSURE WARNING LIGHT
This light comes on when the ignition key
is turned to the ONº position. It goes off
after a few seconds. This indicates that
the tire pressure warning system is func-
tioning properly.
If the low tire pressure warning light
comes on or blinks while driving, do
the following.If the warning light comes on:
1. Adjust the tire inflation pressure to
the specified level as soon as pos-
sible. (See Tiresº on page 410 in
Section 8.)
2. Push the tire pressure warning sys-
tem reset switch for a few seconds
and make sure the warning light
goes off.
If the light remains on after the reset
switch has been pushed, have the tire
pressure warning system checked at your
Toyota dealer.
If you have a flat tire, replace it with the
spare tire. For details, see If you have
a flat tireº on page 337 in Section 4.
If the warning light blinks once every
second:
The low tire pressure warning system may
be malfunctioning. Contact your Toyota
dealer.
If the warning light blinks twice every
second:
The low tire pressure warning system
needs to be initialized. Reset the system
with the tire pressure warning system re-
set switch. (To reset the system, see
TIRE PRESSURE WARNING SYSTEM
RESET SWITCHº.)The tire pressure warning system does
not function properly under certain cir-
cumstances. In the following cases, the
low tire pressure warning light may not
come on even if the tire inflation pres-
sure is low, or it may come on when
the tire inflation pressure is actually
normal.
A compact spare tire, snow tires, or
tire chains are used.
The tire inflation pressure is excessive-
ly higher than specified, or tire inflation
pressure suddenly drops due to burst-
ing or other causes.
The vehicle is driven on a slippery
road surface such as rough or frozen
roads.
The vehicle speed is less than 30 km/h
(19 mph) or more than 100 km/h (62
mph), and the driving duration is less
than 5 minutes.
The tires differ in tread pattern or
manufacturer.
The tires are not the specified size.
The tread wear is very different among
the installed tires.
Rapid acceleration/deceleration or
sharp turns is continued.

The loading is over the limit or imbal-
anced.
Initialization was not performed correct-
ly after replacing or rotating tires or
wheels.
The outside temperature is below 0C
(32F) or above 40C (104F).
CAUTION
When the tire pressure warning light
comes on, observe the following in-
structions:
Adjust the tire inflation pressure to
the specified level as soon as pos-
sible.
Avoid abrupt steering wheel maneu-
vering and braking. If the vehicle
tires deteriorate, you could lose
control of the steering wheel or the
brakes, causing death or serious in-
jury.
Note: The tire pressure monitoring
system on your vehicle will warn you
when one of your tires is significantly
under- inflated and when some com-
binations of your tires are significant-
ly under- inflated. However, there are
other combinations of significantly
under- inflated tires for which your
tire pressure monitoring system may
not warn you. These other combina-
tions are relatively common, account-
ing for approximately half the
instances in which vehicles have sig-
nificantly under- inflated tires. For ex-
ample, your system may not warn you
when both tires on the same side or
on the same axle of your vehicle are
significantly under- inflated. It is par-
ticularly important, therefore, for you
to check the tire pressure in all of
your tires regularly and maintain
proper pressure.
TIRE PRESSURE WARNING SYSTEM
RESET SWITCH
The tire pressure warning system need
to be initialized in the following condi-
tions:
When the low tire pressure warning
light blinks twice every second
After replacing or rotating tires or
wheels
When initializing the system, the pres-
ent tire condition is stored as a stan-
dard.

'05 HIGHLANDER_U (L/O 0409)

2005 HIGHLANDER from Nov. '04 Prod. (OM48570U)
To initialize the system, perform the fol-
lowing:
1. Park the vehicle at a safe place and
apply the parking brake. Stop the en-
gine.
2. Adjust the pressure of all the installed
tires to the specified level. (See Tiresº
on page 410 in Section 8.)
3. Turn the ignition key to ONº.
If the low tire pressure warning light
comes on, push the reset switch for a
few seconds and make sure the warn-
ing light goes off.
4. Push and hold the reset switch until
the low tire pressure warning light
blinks three times.
Initialization is completed after driving at
the speeds of 30 km/h (19 mph) or over
for more than one hour. If the following
driving conditions are satisfied, initializa-
tion will be completed in about one hour.
The vehicle speed is between 50 km/h
(31 mph) and 100 km/h (62 mph).
The roads are dry, smooth and straight.
The number of passengers is 1 or 2
(including driver).
When initializing the system, make sure
the low tire pressure warning light blinks
three times. If the warning light does not
blink three times, initializing will be failed
and the tire pressure warning system will
not function properly.
Do not push the reset switch without ad-
justing the tire inflation pressure to the
specified level. Otherwise, the low tire
pressure warning light may not come on
even if the tire pressure is low, or it may
come on when the tire inflation pressure
is actually normal.
If you push the reset switch while the
vehicle is moving, initialization is not per-
formed.If the low tire pressure warning light does
not blink when you push and hold the
reset switch, have the low pressure warn-
ing system checked at your Toyota dealer.
When the warning light blinks twice every
second while driving, you may be unable
to reset the system. In this case, set the
system again according to the above pro-
cedure.
