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
engine oil replacement. Reset the system
by the following procedure:1. Turn the ignition switch to the “OFF” position with the trip meter A reading
shown. (For details, see “Odometer and
two trip meters” on page 186 in this
Section.)
2. Turn the ignition switch to the “ON” position while holding down the trip
meter reset knob.
Hold down the knob for at least 5
seconds. The trip meter A indicates
“000000” and the light goes off.
If the system fails to reset, the light will
continue flashing.
(h) 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. (i) “ABS” Warning Light
The light comes on when the ignition
switch is turned to the “ON” position. If
the anti
−lock brake system and the brake
assist system work properly, the light
turns off after a few seconds. Thereafter,
if either of the systems malfunctions, the
light comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
following systems do not operate, but the
brake system still operates conventionally.
Anti −lock brake system
Brake assist system
Traction control system
“AUTO LSD” system
Vehicle stability control system
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate,
so that the wheels will lock up during a
sudden braking or braking on slippery
road surfaces.
If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the components monitored by
the warning light system. Contact your
Toyota dealer as soon as possible to
service the vehicle.
The light does not come on when the
ignition switch is turned to the “ON”
position, or remains on.
The light comes on while you are dri-
ving.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” 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 antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.

(j) “VSC OFF” warning light
The light flashing warns that there is a
problem somewhere in the following.
Vehicle stability control system
Traction control system
“AUTO LSD” system
The light will come on when the ignition
switch is turned to the “ON” position, and
will go off after a few seconds.
If the light flashes on while driving, the
above mentioned systems do not work.
However, as conventional braking operates
when applied, there is no problem to con-
tinue your driving.
In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition switch is turned to the
“ON” position.
The warning light remains on after the
ignition switch is turned to the “ON”
position.
The warning light flashes while driving. (k) Open Door Warning Light
This light remains on until all the doors
are completely closed.
The buzzer also sounds once when any
of the doors is not completely closed at
the vehicle speed 5 km/h (3 mph) or
more. Stop the vehicle and close all the
door completely.
(l) SRS Warning Light
This light will come on when the igni-
tion switch is turned to the “ON” posi-
tion. After about 6 seconds, the light
will go off. This means the systems of
the airbag and front seat belt preten-
sioners are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors, driv-
er ’s seat position sensor, driver ’s seat belt
buckle switch, front passenger occupant
classification system
∗, passenger airbag
off switch, passenger airbag on −off indica-
tor light, seat belt pretensioner assem-
blies, inflators, “RSCA OFF” indicator light,
interconnecting wiring and power sources.
∗: The front passenger occupant classifica-
tion system includes the front passenger
occupant classification ECU, load sensor
and front passenger ’s seat belt buckle
switch.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.
The light does not come on when the
ignition switch is turned to the “ON”
position or remains on for more than
6 seconds.
The light comes on while driving.
(m) Tire Pressure Warning Light
This light warns that the tire inflation pres-
sure of one or more of your tires (except
for the temporary spare tire) is low. The
light comes on when the ignition switch is
turned to the “ON” position. It goes off
after a few seconds. This indicates that
the tire pressure warning system is func-
tioning properly.

Use the front drive control switch knob
to select the following transfer modes.
“2WD” (high speed position, twowheel
drive): Front drive control switch knob at
“2WD”
Use this for normal driving on dry hard −
surfaced roads. This position gives greater
economy, quietest ride, least wear and
better vehicle control.
“4H” (high speed position, fourwheel
drive): Front drive control switch knob at
“4H”
The “4HI” (high speed four −wheel drive)
indicator light comes on when the “4H”
mode is selected.
Use this for greater traction than two−
wheel drive. (When you experience a loss
of power, such as wheel spinning.) This
position provides greater traction than
two −wheel drive.
In this mode, the vehicle stability control
system is off. (See “Vehicle stability
control system” on page 248 in this
Section.)
“4L” (low speed position, fourwheel
drive): Front drive control switch knob at
“4L” The “4LO” (low speed four
−wheel drive)
indicator light comes on when the “4L”
mode is selected.
Use this for maximum power and traction.
Use “4L” position for climbing or descend-
ing steep hills, off −road driving, and hard
pulling in sand, mud or deep snow.
See “(c) Shifting procedure” for further in-
structions.
In this mode, the vehicle stability control
system is off. (See “Vehicle stability
control system” on page 248 in this
Section.)
Fourwheel drive system
(a) Front drive control

2422007 TUNDRA from Jul. ’07 Prod. (OM34463U)
The traction control system automatical-
ly helps prevent the spinning of rear
wheels (twowheel drive models) or 4
wheels (fourwheel drive models) when
the vehicle is started or accelerated on
slippery road surfaces.
When the ignition switch is turned to the
“ON” position, the system automatically
turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power to the rear wheels (twowheel
drive models) or 4 wheels (fourwheel
drive models) cannot be maintained,
even though the traction control sys-
tem is in operation. Do not drive the
vehicle under any speed or maneuver-
ing conditions which may cause the
vehicle to lose traction control. In si-
tuations where the road surface is
covered with ice or snow, your ve-
hicle should be fitted with snow tires
or tire chains. Always drive at an ap-
propriate and cautious speed for the
present road conditions.

NORMAL DRIVING MODE
Leave the system on during the ordi-
nary driving so that it can operate
when needed.
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
begins to move. This means that the trac-
tion control system is in the self−check
mode, but does not indicate a malfunction.
When the traction control system is oper-
ating, the following conditions occur:
The system controls the spinning of the
rear wheels (two −wheel drive models)
or 4 wheels (four −wheel drive models).
At this time, the slip indicator light
blinks.
You may feel vibration or noise in your
vehicle, caused by operation of the
brakes. This indicates the system is
functioning properly.
The slip indicator light comes on for a few
seconds when the ignition switch is turned
to the “ON” position. If the indicator light
does not come on when the ignition is
turned on, contact your Toyota dealer.

The brake actuator temperature increases
during continuous operation of the follow-
ing systems under conditions such as on
slippery roads.
Traction control system
“AUTO LSD” system
If the brake actuator temperature becomes
too high while any of the systems is oper-
ating, a buzzer will start to sound intermit-
tently to indicate that the traction control
system can no l onger operate. In this
case, immediately stop your vehicle at a
safe place.
If the system continues to operate, the
buzzer sound changes from intermittent to
continuous. (The continuous buzzer
sounds for about 3 seconds.)
At the time, the slip indicator light will
come on and the traction control system
temporarily stops operating in order to
protect the brake actuator. (Although the
traction control system does not operate,
it is no problem to continue driving.) The
system will be automatically restored after
a short time and the slip indicator light
goes off.XS17010a
TRACTION CONTROL OFF MODE
(twowheel drive mode only)
When getting the vehicle out of mud or
newly fallen snow, etc., it may be bene-
ficial to turn off the traction control
system. This system that controls en-
gine performance interferes with the
process of freeing rear wheels.
To turn off: Briefly push the “VSC OFF”
switch.
The “AUTO LSD” and slip indicator lights
will come on.
The vehicle stability control system is al-
ways activated, even if the traction control
system is turned off. To turn on: Briefly push the “VSC OFF”
switch once again.
The “AUTO LSD” and slip indicator lights
will go off.
If the engine is turned off while the
“AUTO LSD” and slip indicator lights are
on and then restarted, the indicator lights
will turn off automatically.
When you push and hold the “VSC OFF”
switch for 3 seconds or more with the
vehicle stopped, turn off the vehicle stabil-
ity control system. See “Vehicle stability
control system” on page 248 in this Sec-
tion.
“AUTO LSD” and slip indicator lights come
on for a few seconds when the ignition
switch is turned to the “ON” position. If
the indicator lights do not come on when
the ignition switch is turned to the “ON”
position, contact your Toyota dealer.
CAUTION
Do not drive with the traction control
system continuously turned off.

XS17009
The “AUTO LSD” system aids traction
by using the traction control system to
control engine performance and braking
when one of the rear wheels begins to
spin.
This system should be used only when
wheel spinning occurs in a ditch or
rough surface.
This system is effective in case one of
the rear wheels is spinning.
