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.

If the tire pressure warning light does not
blink slowly three times when you push
and hold the tire pressure warning reset
switch, initialization has failed and the tire
pressure warning system may not work
properly. In this case, initialize the system
again. If initialization cannot be performed,
have the system checked at your Toyota
dealer.
CAUTION
Do not push the tire pressure warn-
ing reset switch without first adjust-
ing the tire inflation pressure to the
specified level. Otherwise, the tire
pressure warning light may not come
on even if the tire inflation pressure
is low, or it may come on when the
tire inflation pressure is actually nor-
mal.

Parking brake

262
2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
When parking, firmly apply the parking
brake to avoid inadvertent creeping.
To set: Fully depress the parking brake
pedal. For better holding power, first de-
press the brake pedal and hold it while
setting the parking brake.
To release: Depress the parking brake
pedal once again.
To remind you that the parking brake is
set, the parking brake reminder light in
the instrument panel remains on until you
release the parking brake.
CAUTION
Before driving, be sure the parking
brake is fully released and the park-
ing brake reminder light is off.
The cruise control is designed to main-
tain a set cruising speed without requir-
ing the driver to operate the accelera-
tor. Cruising speed can be set to any
speed above 40 km/h (25 mph).
Within the limits of the engine’s capabili-
ties, cruising speed can be maintained up
or down grades. However, changes in ve-
hicle speed may occur on steeper grades.
CAUTION
To help maintain maximum control
of your vehicle, do not use the
cruise control when driving in
heavy or varying traffic, or on slip-
pery (rainy, icy or snowcovered) or
winding roads.
Be careful about vehicle speed as
it may increase when driving down-
hill with the cruise control on.

TURNING THE SYSTEM ON AND OFF
To turn the cruise control on, press the
“ON−OFF” button. The “CRUISE” indicator
light on the instrument panel will come on
to indicate that the cruise control is opera-
tional. Pressing the “ON −OFF” button
again turns the system off.
When the system is turned off, cruising
speed must be reset when the cruise con-
trol is turned on again.
When the engine switch is turned off, the
system is also automatically turned off. To
use the cruise control again, press the
“ON −OFF” button again to turn it on.

CAUTION
To avoid accidentally engaging the
cruise control, turn the system off
when it is not in use. Make sure the
“CRUISE” indicator light is off.
XS17023
SETTING THE CRUISING SPEED
5−speed models—The transmission must
be in the “D” position or the shift range
position must be in “4” (fourth range) or
“5” (fifth range) in “S” mode before you
set the cruising speed.
6 −speed models—The transmission must
be in the “D” position or the shift range
position must be in between “4” (fourth
range) and “6” (sixth range) in “S” position
before you set the cruising speed. Bring your vehicle to the desired speed,
push the lever down in the “
−SET” direc-
tion and release it. This sets the vehicle
at that speed. If the speed is not satisfac-
tory, tap the lever up for a faster speed,
or tap it down for a slower speed. Each
tap changes the set speed by 1.6 km/h
(1.0 mph). You can now take your foot off
the accelerator pedal.
If you need acceleration—for example,
when passing—depress the accelerator
pedal enough for the vehicle to exceed
the set speed. When you release it, the
vehicle will return to the speed set prior
to the acceleration.
CANCELLING THE CRUISE CONTROL
The cruise control may be temporarily
cancelled by the driver or by the system
itself under certain circumstances. Tempo-
rary cancellation allows the set cruising
speed to remain in memory.
The cruise control can be temporarily can-
celled by doing the following:
Pulling the lever in the “CANCEL” di-
rection and releasing it
Depressing the brake pedal
Under certain circumstances, the cruise
control is temporarily cancelled:

264
2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
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.
The “CRUISE” indicator light remains on
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
lever is held down, the vehicle speed will
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.
The indicator light goes out after it
comes on.
If this is the case, contact your Toyota
dealer and have your vehicle inspected.

3. Instantaneous fuel consumption
(“INST MPG” or “INST L/100 km”)
The instantaneous fuel consumption is
calculated and displayed based on dis-
tance and fuel consumption at 20 revo-
lutions of the engine.
The displayed value is updated for a short
time.
An accurate figure may not be shown if
the vehicle is driving down a long slope,
and engine brake is applied. (The display
will indicate the extremely low fuel con-
sumption.)
When the vehicle is stopped with the en-
gine running, “ −−, −MPG” will be shown
on the display.
The calculation is reset when the engine
switch is turned off. 4. Driving range (“RANGE MI” or
“RANGE km”)
The distance the vehicle can travel with
the remaining fuel is calculated and
displayed based on the quantity of re-
maining fuel and past fuel consumption.
The driving range display indicates the
approximate distance that you can drive
until the fuel gauge reaches “E”. It is
different from the actual distance traveled.
The displayed value is updated every time
the fuel equivalent for 1 mile or 1 km is
consumed.
Every time you refuel the vehicle, the cal-
culation is reset.
The actual driving range varies with driv-
ing habits and road conditions. If fuel effi-
ciency is good, the driving range will be
longer than indicated. If fuel efficiency is
poor, the driving range will be shorter than
indicated.
If the low fuel level warning light comes
on, refuel the vehicle even if the display
indicates that the vehicle can be driven
further.

Long reach
type
Your engine is fitted with long reach
iridiumtipped spark plugs.
NOTICE
Use only iridiumtipped spark plugs.
Do not adjust gaps for engine perfor-
mance smooth driveability.
For details about the spark plug type, see
“Service specifications” on page 589 in
Section 8. The tandem master cylinder brake system
is a hydraulic system with two separate
sub
−systems. If either sub −system s hould
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
bring the vehicle to a stop with normal
pedal pressure. There is enough reserved
vacuum for one or two stops—but no
more!
CAUTION
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your reserved vacu-
um.
Even 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.
