The vehicle skid control system helps
provide integrated control of the sys-
tems such as antilock brake system,
traction control, engine control, etc.
This system automatically controls the
brakes and engine to help prevent the
vehicle from skidding when cornering
on a slippery road surface or operating
steering wheel abruptly.
This system will activate when your ve-
hicle speed reaches or exceeds 15 km/h
(9 mph), and will deactivate when the ve-
hicle speed reduced to below 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
is started. This means that the system is
in the selfcheck mode but does not indi-
cate a malfunction.CAUTION
Do not rely excessively on the ve-
hicle skid control system. Even if
the vehicle skid control system is
operating, you must always drive
carefully and attentively to avoid
serious injury. Reckless driving will
result in an unexpected accident. If
the slip indicator light flashes and
an alarm sounds, special care
should be taken while driving.
Only use tires of specified size. The
size, manufacture, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, different type or
size, the vehicle skid control sys-
tem may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer. (See
“Checking and replacing tires” in
Section 72.)
In situations where the road surface
is covered with ice or snow, your
vehicle should be fitted with snow
tires or tire chains.
If the vehicle is going to skid during driv-
ing, the slip indicator light blinks and an
alarm sounds intermittently. Special care
should be taken while driving.
The slip indicator light comes on for a few
seconds when the ignition key is turned
to “ON”. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer.

“VSC” warning light
This light warns that there is a problem
somewhere in the vehicle skid control sys-
tem or the traction control system.
The light will come on when the ignition
key is turned to “ON” and will go off after
a few seconds.
If the light comes on while driving, the
system does not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition key is turned to “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
ing.
The “TRAC OFF” indicator light will come
on when the “VSC” warning light comes
on even if the “TRAC OFF” switch is not
pushed.

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 while depressing the brake pedal.
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 allows you to cruise
the vehicle at a desired speed over 40
km/h (25 mph) with your foot off the
accelerator pedal.
Your cruising speed can be maintained
although a slight speed change may occur
when driving up or down gradient, within
the limits of engine performance. On
steeper hills, a greater speed change will
occur so it is better to drive without the
cruise control.
When the cruise control is on, the driving
pattern of the automatic transmission is
fixed in the normal position, regardless of
the position of the selector switch.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.
Avoid vehicle speed increases when
driving downhill. If the vehicle
speed is too fast in relation to the
cruise control set speed, cancel the
cruise control then downshift the
transmission to use engine braking
to slow down.
Cruise control

1392003 AVALON (OM41401U)
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 PRESET SPEED
You can cancel the preset speed by:
a. Depressing the brake pedal.
b. Pushing “CANCEL” button and releas-
ing it.
c. Pushing “ON/OFF” button.
If the vehicle speed falls below about 40
km/h (25 mph), the preset speed will be
automatically cancelled.
If the vehicle speed drops 16 km/h (10
mph) below the preset speed, the preset
speed will be also automatically cancelled.
If the preset speed automatically cancels
out for any other reasons, have your ve-
hicle checked by your Toyota dealer at the
earliest opportunity.RESETTING TO A FASTER SPEED
Push “RES ACC” button and hold it. Re-
lease the button the desired speed is at-
tained. While the button is pushed, the
vehicle will gradually gain speed.
When the difference between the actual
vehicle speed and the set speed is less
than 5 km/h (3 mph), the set speed can
be increased 1.6 km/h (1 mph) each time
by pushing “RES ACC” button quickly
within 0.6 seconds.
However, a faster way to reset is to ac-
celerate the vehicle and then push
“COAST SET” button.
RESETTING TO A SLOWER SPEED
Push “COAST SET” button and hold it.
Release the button when the desired
speed is attained. While the button is
pushed, the vehicle speed will gradually
decrease.
When the difference is 5 km/h (3 mph) or
more, the vehicle will cruise with its actu-
al speed. When the difference between the
actual vehicle speed and the set speed is
less than 5 km/h (3 mph), the set speed
can be lowered 1.6 km/h (1 mph) each
time by pushing “COAST SET” button
quickly within 0.6 seconds.However, a faster way to reset is to de-
press the brake pedal and then push
“COAST SET” button.
Even if you turn off the overdrive switch
with the cruise control on, engine braking
will not be applied because the cruise
control is not cancelled. To decrease the
vehicle speed, reset to a slower speed
with the cruise control button or depress
the brake pedal. If you use the brake
pedal, cruise control is cancelled.
RESUMING THE PRESET SPEED
If the preset speed is cancelled by push-
ing “CANCEL” button or by depressing the
brake pedal, pushing “RES ACC” button
will restore the speed set prior to can-
cellation. However, once the vehicle speed
falls below about 40 km/h (25 mph), the
preset speed will not be resumed.
CRUISE CONTROL FAILURE WARNING
If “CRUISE” indicator light in the instru-
ment cluster flashes when using the
cruise control, push “ON/OFF” button to
turn the system off and then push it again
to turn it on.
If any of the following conditions then oc-
curs, there is some trouble in the cruise
control system.

After setting the unit, push the “MODE”
button until the display returns to normal
calendar mode.1. Instantaneous fuel consumption
(“INST ECON”)
The instantaneous fuel consumption is
calculated and displayed based on driv-
ing distance and fuel consumption for
2 seconds with the engine running.
The displayed value is updated every 2
seconds.
Note that an accurate figure may not be
shown in the following cases.
When the vehicle is stopped with the
engine running, the display will indicate
the extremely high fuel consumption.
When the vehicle is driving down a
long slope, applying the engine brake,
the display will indicate the extremely
low fuel consumption.
The calculation is reset when the ignition
switch is turned off.2. Average fuel consumption after re-
fueling
(“AVG ECON”)

The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an expressway, making it
appear that oil is excessively consumed
after driving at high speeds.
IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in prop-
er vehicle maintenance is to keep the en-
gine oil at the optimum level so that oil
function will not be impaired. Therefore, it
is essential that the oil level be checked
regularly. Toyota recommends that the oil
level be checked every time you refuel
the vehicle.
NOTICE
Failure to check the oil level regularly
could lead to serious engine trouble
due to insufficient oil.
For detailed information on oil level check,
see “Checking the engine oil level” in Sec-
tion 72.
Your engine is fitted with iridiumtipped
spark plugs.
NOTICE
Use only iridiumtipped spark plugs
and do not adjust gaps for your en-
gine performance and smooth drive-
ability.
The tandem master cylinder brake system
is a hydraulic system with two separate
subsystems. If either subsystem should
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will be longer. 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
powerassist 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!

2162003 AVALON (OM41401U)
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
be longer.
ANTILOCK BRAKE SYSTEM
(with “ABS” warning light)
The antilock brake system is designed
to help prevent lockup of the wheels
during a sudden braking or braking on
slippery road surfaces. This assists in
providing directional stability and steer-
ing performance of the vehicle under
these circumstances.
Effective way to press the ABS brake
pedal: When the antilock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the antilock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake in a panic stop. This
will result in reduced braking performan-
ce.
The antilock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).Depressing the brake pedal on slippery
road surfaces such as on the manhole
cover, the steel plate under the construc-
tion, joints in the bridge, etc. on a rainy
day tends to activate the antilock brake
system.
You may hear a click or motor sound in
the engine compartment for a few seconds
when the engine is started or just after
the vehicle is started. This means that the
antilock brake system is in the self
check mode, and does not indicate a mal-
function.
When the antilock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:
You may hear the antilock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the ve-
hicle body and steering wheel. You
may also hear the motor sound in the
engine compartment even after the ve-
hicle is stopped.
At the end of the antilock brake sys-
tem activation, the brake pedal may
move a little forward.
