(a) Brake System Warning Light andBuzzer
This light comes on in the following cases
when the engine switch is in the “ON”
position.
When the parking brake is applied...
This light comes on for a few seconds
when the engine switch is turned to the
“ON” position even after the parking brake
is released.
If the vehicle speed rises above 5 km/h
(3 mph) with the parking brake applied, a
buzzer sounds.
When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
Have your vehicle checked at your
Toyota dealer in the following case:
The light does not come on even if the
parking brake is applied when the en-
gine switch is in the “ON” position.
The light does not come on initially
even if the engine switch is turned on
with the parking brake released. A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If either of the following conditions
occurs, immediately stop your vehicle
at a safe place and contact your
Toyota dealer.
The light does not turn off even
after the parking brake is released
while the engine is running.
In this case, the brakes may not
work properly and your stopping
distance will become longer. De-
press the brake pedal firmly and
bring the vehicle to an immediate
stop.
The brake system warning light re-
mains on together with the “ABS”
warning light.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely un-
stable during braking.
(b) Driver’s Seat Belt Reminder Light
and Buzzer
The light and buzzer act as a reminder to
buckle up the driver’s seat belt.
Once the engine switch is turned to “ON”,
the reminder light flashes and buzzer
sounds if the driver ’s seat belt is not fas-
tened. Unless the driver fastens the belt,
the light continues flashing and the buzzer
sounds for about 6 seconds.
If the vehicle speed rises above 20 km/h
(12 mph) with the seat belt unfastened,
the buzzer will sound for about 10 sec-
onds. Then, if the seat belt is still unfas-
tened, the buzzer will sound in a different
tone for 20 seconds. Even if the vehicle
speed drops below 20 km/h (12 mph), the
buzzer will continue to sound. To stop the
buzzer, fasten the seat belt. If the buzzer
still sounds, make sure the front passen-
ger ’s seat belt is fastened.

The traction control system automatical-
ly helps prevent the spinning of front
wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the engine switch is turned to “ON”,
the system automatically turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power against front wheels cannot be
maintained, even though the traction
control system is in operation. Do not
drive the vehicle under any speed or
maneuvering conditions which may
cause the vehicle to lose traction
control. In situations where the road
surface is covered with ice or snow,
your vehicle should be fitted with
snow tires or tire chains. Always
drive at an appropriate and cautious
speed for the present road condi-
tions.
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 just after
the vehicle begins to move. This means
that the traction 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
front wheels. At this time, the slip indi-
cator 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 “ON”. If the indicator light does not
come on when the engine switch is turned
on, contact your Toyota dealer.

ating, the following conditions occur:
The system controls the spinning of the
4 wheels. At this time, the slip indica-
tor light blinks.
You may feel vibration or noise in your
vehicle, caused by operation of the

somewhere in the traction control system
or the vehicle stability control system.
The light will come on when the engine
switch 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 engine switch is turned to
“ON”.
The warning light remains on after the
engine switch is turned to “ON”.

The vehicle stability control system
helps provide integrated control of the
systems such as an antilock brake
system, brake assist system, traction
control, engine control, etc. This sys-
tem automatically controls the brakes
and engine to help prevent the vehicle
from skidding when cornering on a slip-
pery road surface or operating steering
wheel abruptly.
The vehicle stability control system is acti-
vated when the vehicle speed is about
more than 15 km/h (9 mph).
You may hear a sound in the engine
compartment for a few seconds just after
the vehicle begins to move. This means
that the system is in the 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
flashes, 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 526 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 engine switch is turned
to “ON”. If the indicator light does not
come on when the engine switch is turned
on, contact your Toyota dealer.

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

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.
Vehicles with runflat tires:
Decelerate to the lowest appropriate
speed as soon as possible. Do not
drive over 90 km/h (55 mph).
Check and 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. Have the
tire replaced 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.
Vehicles with standard tires:
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 spare tire and have the flat tire
repaired by the nearest Toyota deal-
er.
Avoid abrupt maneuvering and bra-
king. If the vehicle tires deteriorate,
you could lose control of the steer-
ing wheel or the brakes.

DYNAMIC LASER CRUISE CONTROL
OPERATIONS
The dynamic laser cruise control func-
tion operates automatically and depend-
ing on whether a vehicle is detected
ahead may change the speed of your
vehicle as follows.
If no vehicle is running ahead of you—1. Cruising at a fixed speed: If there is
no vehicle detected ahead, your
cruising speed is maintained at the
preset speed from about 45 km/h (28
mph) to about 135 km/h (85 mph). The
preset speed is displayed in the
display. For the vehicle speed setting,
see “SETTING THE CRUISING SPEED”
on page 231. If a vehicle is detected ahead of you—
2. Deceleration cruising function: If a
slower moving vehicle is detected
ahead of you, your vehicle cruising
speed decreases within the range of
about 40 km/h (25 mph) to about 135
km/h (85 mph). The display shows the
preset speed, the detected vehicle
ahead and selected vehicle −to −vehicle
distance. If your vehicle gets closer to
the vehicle ahead because of insuffi-
cient automatic deceleration, then the
alarm warns you to also manually ap-
ply brakes.
3. Followup cruising function: After de-
celeration, your vehicle cruising speed
changes in proportion to the speed of
the vehicle ahead to maintain an ap-
propriate distance from your vehicle to
the vehicle ahead. The vehicle −to −ve-
hicle distance can be changed. For de-
tails, see “CHANGING VEHICLE −TO −
VEHICLE DISTANCE” on page 233.
4. Acceleration cruising function: If the
vehicle ahead changes lanes, your ve-
hicle cruising speed will be gradually
increased up to the preset speed, and
your vehicle resumes fixed −speed
cruising.
