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”
or “START”, the reminder light flashes if
the driver ’s seat belt is not fastened. Un-
less the driver fastens the belt, the light
continues flashing.
If the vehicle speed rises above 20 km/h
(12 mph) with the seat belt unfastened,
the buzzer will sound for 30 seconds.
Then, if the seat belt is still unfastened,
the buzzer will sound in a different tone
for 90 more 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.

(e) Stopping
The vehicle can be stopped by depressing
the brake pedal regardless of the gear
position. This is because the clutch is
automatically disengaged to prevent the
engine from stopping. If the shift lever is
in the “E” position, the gear will be down-
shifted to 1st when the vehicle stops.
In case the driver ’s door is opened with
the gear in “E”, “M” or “R” position and
without depressing the brake pedal, a
warning buzzer (long pulse sound) will
sound.
When the engine switch is “ON” and the
vehicle speed is slower than 9 km/h (5
mph), if the shift lever is in “N” position
and the brake pedal is released (not de-
pressed) for approximately 2 seconds, the
shift lever will be locked.
Shift lock system is designed for prevent-
ing the vehicle from starting off by the
unintended activation of the starting assist
system.
The shift lock can be released by de-
pressing the brake pedal without holding
the shift lever.
CAUTION
DWhen stopping, for example, at a
traffic light, be sure to depress the
brake pedal firmly. For your safety,
apply parking brake, too, when
stopping on a hill.
DWhen racing the engine, make sure
that the gear position is in the “N”
position by the gear position indica-
tor. In case the accelerator is oper-
ated with the gear in any other
position, the vehicle may move re-
sulting in an unexpected accident.
DDo not leave your vehicle unat-
tended while the engine is running.
DWhen leaving the vehicle, stop the
engine and park the vehicle with
the gear engaged. In case you need
to leave the vehicle with the engine
running, apply the parking brakes
firmly, and shift the shift lever in
the “N” position. When the driver ’s
door is opened with the shift lever
in the “E” position while stopping
with the engine running, warning
buzzer (long pulse sound) will
sound. If this happens on a hill
when starting off the vehicle, the
vehicle may move unexpectedly and
cause an accident.

(a) Upshift and downshift
Upshifting
Pull the shift lever to the “+” direction
and release it. Every time the lever is
operated, the transmission is upshifted
1 step in the order of 1st→2nd→
3rd→4th→5th gear.
Downshifting
Push the shift lever to the “−” direction
and release it. Every time the lever is
operated, the transmission is down-
shifted in the order of 5th→4th→
3rd→2nd→1st gear.
DTo shift down smoothly, the engine
runs fast in some cases. This is done
intentionally by the system and is not
a malfunction.
DWhen driving down a hill, downshift
and use the engine brakes appropriate-
ly. If necessary, continuous shifting
down is possible. However, if down-
shifting more than 3 steps continuously,
the gear shifting will take more time.
DWhen the outside air temperature is
extremely low, the gear may not down-
shift from 2nd to 1st until the vehicle
stops.
DWhen the gear is shifting, a noise can
be heard in some case. This is not a
malfunction.
DIn case the transmission cannot be en-
gaged to a certain gear position during
shifting due to mechanical malfunction,
the gear will not be engaged and re-
mains in neutral. The “N” in the gear
position indicator will blink and a warn-
ing buzzer (long pulse sound) will
sound until the driver shifts the shift
lever to “N” position.
Unless the system recovers from the
above−mentioned condition (mechanical
malfunction), the gear will still remain
in neutral position even shifting the
shift lever to “M” or “E” position after
the system performs a re−try shifting.
If such conditions continue, contact any
authorized Toyota dealer or repairer, or
another duly qualified and equipped
professional, as soon as possible to
service the vehicle.
DWhen the gear jumped out of position
while driving, the gear is shifted to
proper gear position.
NOTICE
Manual (M) mode dose not shift up
the gear even if the engine speed
reaches the rev−limit.

Maximum allowable speeds
To get on a highway or to pass slower
traffic, maximum acceleration may be nec-
essary. Make sure you observe the follow-
ing maximum allowable speeds in each
gear:
gear km/h (mph)
1 51 (31)
2 95 (59)
3 139 (86)
CAUTION
DBe careful when accelerating, up-
shifting, downshifting or braking on
a slippery surface. Sudden accelera-
tion or engine braking could cause
the vehicle to spin or skid.
DTo drive down a long or steep hill,
reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat and
fail.
DDuring driving the vehicle, do not
shift the shift lever to “N”. The en-
gine brake may not work and you
may get involved in an unexpected
accident. If you return the shift le-
ver from “N” to “M” because of an
unintended shifting, the gear posi-
tion will be changed accordingly to
the current vehicle speed.
DDo not apply the parking brake
while driving. Otherwise, it could
cause a skid and you may get in-
volved in an unexpected accident.
NOTICE
zThe system will not allow shifting
up or down to a gear that would
cause engine over−revving or un-
der−revving. In case of selecting a
gear position that may cause over−
revving, a warning buzzer (short
pulse sound) will sound.
zFrequent downshifting (more than 3
positions continuously) causes the
reduction of transmission life.
(b) Starting off
1. Start the engine as instructed in “How
to start the engine” on page 210 in
Section 3.
2. With your foot holding down the brake
pedal, shift the shift lever to the “M”
position properly. When the shift lever
is shifted to “M” position, the gear will
be shifted to 1st. On a slippery sur-
face, it is possible to start off with the
gear in 2nd. To start off with the gear
in 2nd, shift the shift lever from “N” to
“M” position, then operate the lever to
“+” direction. The gear will be shifted
to 2nd. Before starting off, always
make sure that the gear is engaged by
the gear position indicator, then de-
press the accelerator pedal.
NOTICE
Do not use 2nd gear to start off in
situations where the clutch load is
present such as when facing uphill.
If the gear cannot be engaged to 1st
or 2nd when the shift lever is shifted
from the “N” to “M” position, the “N”
indicator will blink and a warning buzz-
er (long pulse sound) will sound. In
this case, the system will re−try shift-
ing or the driver can operate the shift
lever to shift, as follows.

CAUTION
DWhen stopping, for example, at a
traffic light, be sure to depress the
brake pedal firmly. For your safety,
apply parking brake, too, when
stopping on a hill.
DWhen racing the engine, make sure
that the gear position is in the “N”
position by the gear position indica-
tor. In case the accelerator is oper-
ated with the gear in any other
position, the vehicle may move re-
sulting in an unexpected accident.
DDo not leave your vehicle unat-
tended while the engine is running.
DWhen leaving the vehicle, stop the
engine and park the vehicle with
the gear engaged. In case you need
to leave the vehicle with the engine
running, apply the parking brakes
firmly, and shift the shift lever in
the “N” position. When the driver ’s
door is opened with the shift lever
in the “M” position while stopping
with the engine running, warning
buzzer (long pulse sound) will
sound. If this happens on a hill
when starting off the vehicle, the
vehicle may move unexpectedly and
cause an accident.
NOTICE
zOn an uphill, never hold the vehicle
stop only by the accelerator pedal
operation or when the starting as-
sist system is being activated.
Otherwise the warning buzzer
(pulse sound) will sound and the
clutch may be damaged. In such a
case, pull over and shift the shift
lever to the “N” position. Wait for
around 15 minutes to cool the
clutch before starting again.
zIf the shift lever is operated more
than necessary, the system may not
allow operation of the shift lever
for a certain period of time, and the
gear may not be shifted appropri-
ately. Therefore, do not operate the
shift lever if not necessary.
(f) Parking
Unlike the automatic transmission, the
multi−mode manual transmission does not
have a parking position. The vehicle can
be parked with the shift lever in any posi-
tion.
1. Apply the parking brake firmly.
2. While depressing the brake pedal, shift
the shift lever in the “R” position on a
downhill or a level surface, and the
“M(1)” position on an uphill by confirm-
ing the gear position with the gear
position indicator.
3. Stop the engine.

Traction control system
The traction control system automatical-
ly helps control the spinning of front
wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the engine 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 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.
MS16014
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 isoper-
ating, the following conditions occur:
DThe system controls the spinning of the
front wheels. At this time, the slip indi-
cator light blinks.
DYou 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 any authorized Toyo-
ta dealer or repairer, or another duly qual-
ified and equipped professional.

“VSC” warning light
This light warns that there is a problem
somewhere in the traction control system
or the vehicle stability control system.
The light will come on when the engine
switch is turned to the “ON” position and
will go off after a few seconds.
If the light comes on while driving, the
systemdoes not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.
In the following cases, contact any autho-
rized Toyota dealer or repairer, or another
duly qualified and equipped professional:
DThe warning light does not come on
after the engine switch is turned to the
“ON” position.
DThe warning light remains on after the
engine switch is turned to the “ON”
position.
DThe warning light comes on while driv-
ing.The vehicle stability controlsystem au-
tomatically controls the brakes and en-
gine to help prevent the vehicle from
skidding when cornering on a slippery
road surface or operating steering
wheel 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 the self−check mode but does
not indicate a malfunction.
CAUTION
DDo not rely excessively on the ve-
hicle stability controlsystem. Even
if the system is operating, you
must always drive carefully and at-
tentively. Reckless driving will re-
sult in an unexpected accident and
cause death or serious injury. If the
slip indicator light blinks, and spe-
cial care should be taken while
driving.
DOnly 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, or different type or
size, the vehicle stability control
system may not function correctly.
When replacing the tires or wheels,
contact any authorized Toyota deal-
er or repairer, or another duly quali-
fied professional. (See “Checking
and replacing tires” on page 270 in
Section 7−2.)
DIn situations where the road surface
is covered with ice or snow, your
vehicle should be fitted with snow
tire or tire chains.

200INFORMATION BEFORE DRIVING YOUR TOYOTA
Brake system
The tandem master cylinder brakesystem
is a hydraulic system with two separate
sub−systems. If either sub−system should
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
bringthevehicletoastopwithnormal
pedal pressure. There is enough reserved
vacuum for one or two stops—but no
more!
CAUTION
DDo not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up the reserved vacuum.
DEven 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.
ANTI−LOCK BRAKE SYSTEM
The anti−lock brake system is designed
to help prevent lock−up 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 anti−lock brake system func-
tion is in action, you may feel the brake
pedal pulsating and hear a noise. In this
situation, to let the anti−lock brake sys-
tem work for you, just hold the brake
pedal down more firmly. Do not pump
the brake in a panic stop. This will re-
sult in reduced braking performance.
The anti−lock 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 a manhole cov-
er, a steel plate at a construction site,
joints in a bridge, etc. on a rainy day
tends to activate the anti−lock brake sys-
tem.
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 begins to move. This means
that the anti−lock brake system is in self−
check mode, and does not indicate a mal-
function.
When the anti−lock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:
