2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
NORMAL DRIVING MODE
Leave the system on during ordinary
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 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 engine switch is turned
to the “ON” position. If the indicator light
does not come on when the engine switch
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 this time, the slip indicator light comes
on and the traction control system tempo-
rarily stops operating in order to protect
the brake actuator. (Although the traction
control system does not operate, it is not
a problem to continue driving.) The sys-
tem is automatically restored after a short
time and the slip indicator light goes off.XS17010a
and only one of the rear wheels be-
gins to spin,which also may the rear
wheels.TRACTION CONTROL OFF MODE
(twowheel drive mode only)
When getting the vehicle out of mud or
snow, etc., and only one of the rear
wheels begins to spin, it may be benefi-
cial to turn off the traction control sys-
tem. This system which also controls
engine performance may interfere with
the process of freeing the rear wheels.

The “VSC OFF” indicator light flashes
and the slip indicator light comes on
while driving.
CAUTION
Do not drive with the “AUTO LSD”
system continuously turned on.
The vehicle stability control system
helps provide integrated control of sys-
tems such as the antilock brake sys-
tem, traction control, engine control,
etc. This system automatically controls
the output of the brakes or engine to
help prevent the vehicle from skidding
when cornering on a slippery road sur-
face or when the steering wheel is op-
erated abruptly.
The vehicle stability control system is acti-
vated when the vehicle speed is more
than 15 km/h (9 mph).
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 sys-
tem is in self−check mode, but does not
indicate a malfunction.CAUTION
Do not rely excessively on the ve-
hicle stability control system. Even
if the vehicle stability control sys-
tem is operating, you must always
drive carefully and attentively to
avoid serious injury. Reckless driv-
ing will result in an unexpected ac-
cident. If the slip indicator light
blinks and an alarm sounds, special
care should be taken while driving.
Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, or different type or
size, the vehicle stability control
system may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer. (See
“Checking and replacing tires” on
page 556 in Section 72.)

The “VSC OFF” indicator light flashes
and the slip indicator light comes on
The “VSC OFF” indicator light flashes and
the slip indicator light comes on to warn
that there is a problem somewhere in the
following:
Vehicle stability control system
Traction control system
“AUTO LSD” system
The slight comes on when the engine
switch is turned to the “ON” position, and
will go off after a few seconds.
If the “VSC OFF” indicator light flashes
and the slip indicator light comes on dur-
ing driving, the vehicle stability control
system will not work. However, if the
brakes operate normally when applied, it
is not a problem to continue driving.
In the following cases, contact your Toyota
dealer:
The “VSC OFF” and slip indicator lights
do not come on after the engine switch
is turned to the “ON” position.
The “VSC OFF” indicator light flashes
and the slip indicator light remains on
after the engine switch is turned to the
“ON” position.
The “VSC OFF” indicator light flashes
and the slip indicator light comes on
while driving. The tire pressure warning system warns
you that the tire inflation pressure is
low.
The tire pressure warning system is not
a substitute for checking normal tire infla-
tion pressure. Check the tire inflation
pressure with a tire pressure gauge regu-
larly.
CAUTION
The warning system may not activate
immediately if blowout or sudden air
loss should occur.

The tire pressure warning light comes on
when the engine switch is turned to the
“ON” position and goes off after a few
seconds. This means the tire pressure
warning system is operating properly. If
the tire inflation pressure becomes low,
the light comes on again. In this case,
adjusting the tire inflation pressure will
turn off the light after several minutes. If
the light comes on after blinking for 1
minute, the tire pressure warning system
is not working properly.

CAUTION
If the tire pressure warning light
comes on, be sure to observe the
following precautions. Failure to do
so could cause loss of vehicle control
and result in death or serious injury.
Stop your vehicle in a safe place as
soon as possible. Adjust the tire
inflation pressure immediately.
If the tire pressure warning light
comes on even after tire inflation
pressure adjustment, it is probable
that you have a flat tire. Check the
tires. If the tire is flat, change to
the temporary spare tire and have
the flat tire repaired by the nearest
Toyota dealer.
Avoid abrupt maneuvering and brak-
ing. If the vehicle tires deteriorate,
you could lose control of the steer-
ing wheel or the brakes.

When vehicle speed falls below 40
km/h (25 mph)
When vehicle stability control is acti-
vated
When vehicle speed drops 16 km/h (10
mph) below the set speed, the cruise con-
trol is cancelled and the set speed is
erased from memory.

to indicate that the system is still in op-
eration.
To turn the cruise control off, press the
“ON −OFF” button. Make sure the
“CRUISE” indicator light is off.
If the cruise control automatically cancels
out other than for the above cases, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity.
RESUMING THE CRUISE CONTROL
If the cruise control is temporarily can-
celled, the cruising speed can be resumed
by pushing the lever up in the “+ RES”
direction.
Vehicle speed must be above 40 km/h (25
mph). RESETTING TO A FASTER SPEED
Push the lever up in the “+RES” direction
and hold it. Release the lever when the
desired speed is attained. While the lever
is held up, the vehicle will gradually gain
speed.
However, a faster way to reset is to ac-
celerate the vehicle and then push the
lever down in the “−
SET” direction.
RESETTING TO A SLOWER SPEED
Push the lever down in the “ −SET” direc-
tion and hold it. Release the lever when
the desired speed is attained. While the

gradually decrease.
However, a faster way to reset is to de-
press the brake pedal and then push the
lever down in the “− SET” direction.
Even if you downshift from “D” to “S” with
the cruise control on, engine braking will
not be enabled because the cruise control
is not cancelled. To decrease the vehicle
speed, reset to a slower speed with the
cruise control lever or depress the brake
pedal. If you use the brake pedal, cruise
control is cancelled. CRUISE CONTROL FAILURE WARNING
If the “CRUISE” indicator light flashes
when using the cruise control, press the
“ON
−OFF” button to turn the system off
and then press it again to turn it on.
If any of the following conditions then oc-
curs, there is some trouble in the cruise
control system.
The indicator light does not come on.
The indicator light flashes again.
