GAUGES, METERS AND SERVICE REMINDER INDICATORS129
(a) Brake System Warning Light
This light comes on in the following cases
when the engine switch is in the “ON”
position.
DWhen 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.
DWhen 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 any au-
thorized Toyota dealer or repairer, or
another duly qualified and equipped
professional, in the following cases:
DThe light does not come on even if the
parking brake is applied when the en-
gine switch is in the “ON” position.
DThe light does not come on 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 any au-
thorized Toyota dealer or repairer, or
another duly qualified and equipped
professional.
DThe 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.
DThe brake system warning light re-
mains on together with the “ABS”
warning light.
In this case, not only the anti−lock
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”
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.

CAUTION
If the electric power steering system
warning light comes on, take your ve-
hicle to any authorized Toyota dealer
or repairer, or another duly qualified
and equipped professional, as soon
as possible. In this case, more effort
is required for the steering wheel to
turn than usual. Drive your vehicle
while firmly gripping the steering
wheel.
(o) Light Reminder Buzzer
This buzzer will sound if the driver ’s door
is opened while the engine switch is
turned to the “LOCK” position with the
headlight switch on. Removing the key will
not stop the buzzer as long as the head-
light switch is on.
(p) Warning function of the Multi−mode
manual transmission (Multi−mode
manual transmission only)
When driving, if any incorrect operation
that may cause damage to this system is
performed or if the gear is not shifted as
desired by the driver, the warning buzzer
will sound and the gear position indicator
will blink to warn the driver in some
cases. For details, see “—Warning
functions” on page 154 in Section 1−7.
When the shift lever is shifted to “R”, the
reverse buzzer sounds once. This is to
indicate the shift lever position, not a
malfunction. For details, see “(d) Backing
up” on page 143 or 150 in Section 1−7.CHECKING SERVICE REMINDER
INDICATORS (except the low fuel level
warning light)
1. Apply the parking brake.
2. Turn the engine switch to the “ON”
position, but do not start the engine.
All the service reminder indicators should
come on. The “ABS”, “VSC”, “STOP”, en-
gine coolant temperature, Multi−mode
manual transmission warning lights and
electric power steering system warning
lights go off after a few seconds. The
SRS warning light goes off after 6 sec-
onds.
If any service reminder indicator or warn-
ing buzzer does not function as described
above, have it checked by any authorized
Toyota dealer or repairer, or another duly
qualified and equipped professional, as
soon as possible.

138ENGINE (IGNITION) SWITCH, TRANSMISSION AND PARKING BRAKE
Engine (ignition) switch
MS16003c
“START”—Starter motor on. The key
will return to the “ON” position when
released.
For starting tips, see page 209 in Section
3.
“ON”
—Engine on and all accessories on.
This is the normal driving position.“ACC”—Accessories such as the radio
operate, but the engine is off.
“LOCK”—Engine is off and the steering
wheel is locked. The key can be re-
moved only at this position.
When the engine switch is turned from the
“ACC” to the “LOCK” position or 20 sec-
onds have elapsed since the engine
switch is turned from the “ON” to the
“ACC” position, the engine immobilizer
system is automatically set. (See “Engine
immobilizer system” onpage 13 in Section
1−2.)
When starting the engine, the engine
switch may seem stuck at the “LOCK”
position. To free it, first be sure the key
is pushed all the way in, and then rock
the steering wheel slightly while turning
the key gently.
It is not a malfunction if the needles on
all meters and gauges move slightly when
the engine switch is turned to the “ACC”,
“ON” or “START” position.
CAUTION
Never remove the key when the ve-
hicle is moving, as this will lock the
steering wheel and result in loss of
steering control.
NOTICE
Do not leave the engine switch in the
“ON” position if the engine is not
running. The battery will discharge
and the ignition could be damaged.
