When the ignition key is turned to the
“ON” position, the light does not come
on, remains on for more than 6 sec-
onds or flashes.
The light comes on or starts flashing
while driving. If the light stays on, it indicates that the
SRS driver and front passenger airbag
system and/or front passenger occupant
classification system and “AIRBAG ON”
and “AIRBAG OFF” indicator lights have a
problem. If the light flashes, the SRS side
airbag system and/or curtain shield airbag
system have a problem.

indicator light will come on if there is a
malfunction in the front passenger occu-
pant classification system.
In the following cases, contact your Toyota
dealer as soon as possible:
The SRS front airbags have been in-
flated.
The front of the vehicle (shaded in the
illustration) was involved in an accident
that was not severe enough to cause
the SRS front airbags to inflate.
The pad section of the steering wheel
or dashboard (shaded in the illustra-
tion) is scratched, cracked, or other-
wise damaged.

To adjust the steering wheel position,
push down the lock release lever. Then
tilt the steering wheel to the desired
angle, push or pull it to the desired
steering column length and pull up the
lock release lever.
CAUTION
Do not adjust the steering wheel
while the vehicle is moving. Doing
so may cause the driver to mishan-
dle the vehicle and an accident may
occur resulting in death or serious
injuries.
After adjusting the steering wheel,
try moving it up and down or for-
ward and rearward to make sure it
is locked in position.
Adjust the mirror so that you can just
see the side of your vehicle in the mir-
ror.
Be careful when judging the size or dis-
tance of any object seen in the outside
rear view mirror on the passenger ’s side
because it is a convex mirror. Any object
seen in a convex mirror will look smaller
and farther away than when seen in a flat
mirror.

“START”—Starter motor on. The key
will return to the “ON” position when
released.
For starting tips, see page 403 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.
If you leave the key in the “ACC” or
“LOCK” position and open the driver’s
door, a buzzer will remind you to remove
the key.“LOCK”—Engine is off and the steering
wheel is locked. The key can be re-
moved only at this position.
You must push in the key to turn the key
from “ACC” to the “LOCK” position. The
selector lever must be put in the “P” posi-
tion before pushing the key.
Vehicles with engine immobilizer system—
Once you remove the key, the engine im-
mobilizer system is automatically set. (See
“Engine immobilizer system” on page 13
in Section 1−
2.)
When starting the engine, the key 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 needle on all
meters and gauges move slightly when the
key is turned to the “ACC”, “ON” or
“START” position.
NOTICE
Do not leave the key in the “ON”
position if the engine is not running.
The battery will discharge and the
ignition could be damaged.

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.
This system activates 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 474 in Section 72.)
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.

For details about the run−flat tires, see
“Run −flat tires” on page 476 in Section
7 −2.
If the warning light blinks once every
second:
The low tire pressure warning system may
be malfunctioning. Contact your Toyota
dealer.
If the warning light blinks twice every
second:
The low tire pressure warning system
needs to be initialized. Reset the system
with the tire pressure warning system re-
set switch. (To reset the system, see
“TIRE PRESSURE WARNING SYSTEM
RESET SWITCH”.)
The tire pressure warning system does
not function properly under certain cir-
cumstances. In the following cases, the
low tire pressure warning light may not
come on even if the tire inflation pres-
sure is low, or it may come on when
the tire inflation pressure is actually
normal.
The tread wear is uneven among the
tires.
A compact spare tire, snow tires, or
tire chains are used.
The tire inflation pressure is excessive-
ly higher than specified, or tire inflation
pressure suddenly drops due to burst-
ing or other causes.
The vehicle is driven on a slippery
road surface such as rough or frozen
roads.
The vehicle speed is less than 30 km/h
(19 mph) or more than 100 km/h (62
mph), and the driving duration is less
than 5 minutes.
The tires differ in tread pattern or
manufacturer.
The tires are not the specified size.
The tread wear is very different among
the installed tires.
The pressure of two or more tires
drops at the same time.
Rapid acceleration/deceleration or
sharp turns is continue.
Towing a trailer.
The loading is over the limit or imbal-
anced.
Initialization was not performed correct-
ly after replacing or rotating tires or
wheels.
Vehicles with vehicle stability control
system—The outside temperature is be-
low 0 C (32F) or above 40 C (104 F).
CAUTION
When the tire pressure warning light
comes on, observe the following in-
structions:
Vehicles with the standard tires—
Adjust the tire inflation pressure to
the specified level as soon as pos-
sible.
Vehicles with the runflat tires—
Decelerate as soon as possible to
the lowest appropriate speed that
conditions permit. Do not drive for
longer than 160 km (100 miles) or
over 90 km/h (55 mph).
Avoid abrupt steering wheel maneu-
vering and braking. If the vehicle
tires deteriorate, you could lose
control of the steering wheel or the
brakes, causing death or serious in-
jury.

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. Dynamic laser cruise control allows you
to drive at a selected cruising speed
over about 45 km/h (28 mph) with your
foot off the accelerator pedal, maintain-
ing an appropriate vehicletovehicle
distance.
CAUTION
Do not rely excessively on dynamic
laser cruise control in order to avoid
serious injury or death, or to prevent
accidents or to control the vehicle’s
speed in emergency situations. Do
not use cruise control except in ap-
propriate road and traffic conditions.
Always drive carefully and attentively.
Before using dynamic laser cruise
control, read and understand the fol-
lowing instructions.

Depending on the road configura-
tion (curved, left and right continu-
ous curved, the start or end of a
curve, or narrow driving lanes due
to road construction) or your ve-
hicle condition (steering wheel ma-
neuvering, position in the lane, or
unstable driving because of an acci-
dent or breakdown), vehicles in oth-
er lanes or surrounding objects
may be detected, resulting in a con-
trol failure or the approach warning
activation. This may also result in
a very close distance between vehi-
cles due to a failure to detect the
vehicle ahead.
Dynamic laser cruise control should not
be used in circumstances which are inap-
propriate for any cruise control, such as
entering free way on−ramps or off −ramps.
CAUTION
Do not use dynamic laser cruise
control when exiting from or when
entering or merging onto a freeway.
When you are following a slower
moving vehicle and exiting, the sen-
sor does not detect the vehicle and
will accelerate to the preset speed.
If other vehicles are driving outside
of the laser radar detection range,
a delay in the detection of the ve-
hicle cutting in at short range or
failure to detect a motorcycle run-
ning on the side of the same lane
will occur. In this case, the dynamic
laser cruise control system will not
function properly.
When a slower vehicle in front of
you leaves the lane, the dynamic
laser cruise control will no longer
detect a vehicle ahead and will at-
tempt to accelerate the vehicle to
the faster preset speed.
