(f) Malfunction Indicator Lamp
This lamp comes on when the ignition
switch is set at ON and goes off after
the engine starts. This means that the
warning light system is operating prop-
erly.
If the lamp remains on, or the lamp
comes on while driving, first check the
followings.
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
Loose fuel tank cap
If the fuel tank cap is loose, securely
tighten it.
These cases are temporary malfunctions.
The malfunction indicator lamp will go off
after taking several driving trips.
If the lamp does not go off even after
several trips, contact your Toyota dealer
as soon as possible. If the fuel tank is not empty or the fuel
tank cap is not loose...
There is a problem somewhere in the
engine, emission control system, elec-
tronic throttle control system, automatic
transmission electrical system or warn-
ing light system itself.
Contact your Toyota dealer as soon as
possible to service the vehicle.
If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle
checked by your Toyota dealer as soon as
possible.
Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the engine off.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
Emissions Inspection and Maintenance
(I/M) programs
Your vehicle may not pass a state
emission inspection if the malfunction
indicator lamp remains on. Contact your
Toyota dealer to check your vehicle’s
emission control system and OBD
(On −Board Diagnostics) system before
taking your vehicle for the inspection.
For details, see “Emissions Inspection and
Maintenance (I/M) programs” on page 340
in Section 6.
(g) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.

(k) “VSC” Warning Light
The light warns that there is a problem
somewhere in the vehicle stability control
system or traction control system.
The light will come on when the ignition
switch is set at ON and will go off after
about a few seconds.
If the light comes on while driving, the
vehicle stability control system and trac-
tion control system do not work. However,
as conventional braking operates when ap-
plied, there is no problem to continue your
driving.
In the following cases, contact your Toyota
dealer:
The light does not come on after the
ignition is turned to on.
The light is left on after the ignition is
turned to on.
The light comes on while driving.(l) Low Windshield Washer Fluid Level
Warning Light

The light will come on when the ignition
switch is set at ON and will go off after
a few seconds.
If it comes on, have your vehicle checked
by your Toyota dealer. (n) Engine Oil Replacement Reminder
Light (for vehicles sold in U.S.A.)
This light acts as a reminder to replace
the engine oil.
This light will come on when the ignition
switch is set at ON and will go off after
about a few seconds.
When you drive for about 7200 km (4500
miles) after the engine oil replacement,
this light illuminates for about 3 seconds
and then flashes for about 15 seconds
with the ignition switch is set at ON. If
you continue driving without replacing the
engine oil, and if the distance driven ex-
ceeds 8000 km (5000 miles), the light will
come on after the ignition switch is set at
ON. The light will remain on thereafter.
If the light is flashing, we recommend that
you replace the engine oil at an early
opportunity depending on the driving and
road conditions. If the light comes on,
replace it as soon as possible.
The system must be reset after the en-
gine oil replacement. Reset the system by
the following procedure: 1. Turn the engine off with the odometer reading shown. (For details, see
“Odometer and two trip meters” on
page 143 in this Section.)

2. Turn the ignition switch is set at ONwhile holding down the trip meter reset
knob.
Hold down the knob for at least 5 sec-
onds. The odometer indicates “000000”
and the light goes off.
If the system fails to reset, the light will
continue flashing.
(o) Smart Key System Warning Light and Buzzer
The light and buzzer warn that there is a
problem somewhere in the operation of
the smart key system. See “Driving and
parking using smart key system” on page
293 in Section 3. (p) Dynamic Laser Cruise Control Mas-
ter Warning Light
This light warns that there is a problem
somewhere in the dynamic laser cruise
control system.
The light will come on when the ignition
switch is set at ON and go off after a few
seconds.
When the light comes on, the alarm
sounds and the warning code will appear
on the display. At this time, dynamic laser
cruise control is cancelled. For details,
see “Dynamic laser cruise control” on
page 172 in Section 1 −7.
(q) Key Reminder Buzzer (vehicles with key cylindertype ignition switch)
This buzzer act as a reminder to remove
the key when you open the driver’s door
with the engine off. CHECKING SERVICE REMINDER
INDICATORS (except the low fuel level
warning light)
1. Apply the parking brake.
2. Open one of the doors. The open door warning light should
come on.
3. Close the door. The open door warning light should go
off.
4. Set the ignition switch at ON, but do not start the engine.
All the service reminder indicators ex-
cept the open door warning light should
come on. The “ABS” and “VSC” warn-
ing lights, low windshield washer fluid
level warning light, automatic headlight
leveling system warning light, engine
oil replacement reminder light and dy-
namic laser cruise master warning light
go off after a few seconds. The SRS

Shift range positions
“5” (Fifth range):
The most suitable gear is selected au-
tomatically between first and overdrive
(fifth) gears according to the vehicle
speed or driving conditions.
“4” (Fourth range):
The most suitable gear is selected au-
tomatically between first and fourth
gears according to the vehicle speed
or driving conditions. Slight engine
braking will be obtained on a downhill
road. Smooth running with less shifting
will be obtained on an uphill road.
“3” (Third range):
The most suitable gear is selected au-
tomatically between first and third
gears according to the vehicle speed
or driving conditions. This range is to
be used when stronger engine braking
is necessary.
“2” (Second range):
First or second gear will be selected
automatically according to the vehicle
speed or driving conditions. This range
is to be used when engine braking
stronger than that of the “3” range
position is necessary.
“1” (First range):
The gear is fixed in first regardless of
vehicle speed or driving conditions.
This range is to be used when maxi-
mum engine braking is necessary.
If you attempt to downshift the transmis-
sion when it is not possible to downshift
due to high vehicle speed, a warning tone
sounds twice.
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
range: range km/h (mph)1 59 (37)
2 106 (66)
3 165 (103)
NOTICE
Do not downshift if you are going
faster than the maximum allowable
speed for the next lower range.
When the “S” mode indicator light does
not come on even with the selector lever
moved to the sequential position, there
may be a problem somewhere in the
system. Have your vehicle checked/re-
paired by your Toyota dealer as soon as
possible. In this case, you can drive in
the same condition as in the “D” position.
(d) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
When driving in the “D” position—Shift the selector lever to sequential
position.
When driving in the “5” range within
the sequential position— Move the selector lever down to the
“− ” side to select the “4” range.
The transmission will downshift to
fourth range and engine braking will be
enabled.
Vehicles with cruise control or dynamic
laser cruise control—When the cruise
control is being used, engine braking
can not be enabled because the cruise
control is not cancelled.

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 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 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 ignition switch is set at
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 traction control system
or the vehicle stability control system.
The light will come on when the ignition
switch is set at 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 switch is set at ON.
The warning light remains on after the
ignition switch is set at ON.
The warning light comes on while driv-
ing.The vehicle stability control system
helps provide integrated control of the
systems such as antilock brake sys-
tem, traction control, engine control,
etc. This system automatically controls
the brakes and engine to help prevent
the vehicle from skidding when corner-
ing on a slippery road surface or oper-
ating 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 reduces 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
begins to move. This means that the sys-
tem 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 and an alarm sounds, spe-
cial 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 stability control
system may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer. (See
“Checking and replacing tires” on
page 357 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.

In the following cases, the preset speed
automatically cancels out:a. The vehicle speed falls below about 40km/h (25 mph).
b. If the vehicle speed drops 16 km/h (10 mph) below the preset speed, the pre-
set speed will also automatically be
cancelled.
c. The slip indicator light blinks and an alarm sounds. (This occurs when the
vehicle is about to skid.)
If cancelled by a. or b., the preset speed
data is cleared and you must set the
speed from the beginning.
If the preset speed automatically cancels
out for other than the above reasons, do
not operate the cruise control. Although it
is no problem to continue driving, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity. RESETTING TO A FASTER SPEED
Push the lever up in the “+ RES” direction
and hold it. Release the lever when the
desired speed is attained. While the lever
is held up, 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 the lever up in the “+ RES”
direction quickly within 0.6 seconds.
However, a faster way to reset is to ac-
celerate the vehicle and then push the
lever down in the “− SET” direction.
RESETTING TO A SLOWER SPEED
Push the lever down in the “
− SET” direc-
tion and hold it. Release the lever when
the desired speed is attained. While the
lever is held down, the vehicle speed will
gradually decrease.
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 the lever down in the “ − SET”
direction quickly within 0.6 seconds. However, a faster way to reset is to ac-
celerate the vehicle and then push the
lever down in the “− SET” direction.
Even if you downshift from “D” position or
“5” (fifth range) to “4” (fourth range) in
sequential mode in the conventional cruise
control mode, engine braking will not be
enabled because this mode is not cancel-
led. To decrease the vehicle’s speed, re-
set to a slower speed with the cruise
control lever 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 pulling
the lever, by depressing the brake pedal
or by activating the vehicle stability con-
trol system, pushing the lever up in the
“+ RES” direction will restore the speed
set prior to cancellation.
If the preset speed is cancelled when ve-
hicle speed falls below about 40 km/h (25
mph), the preset speed will be resumed
by pushing the control lever up in the “+
RES” direction when vehicle speed ex-
ceeds about 40 km/h (25 mph) again.

The threeway catalytic converter is an
emission control device installed in the
exhaust system.
The purpose is to reduce pollutants in the
exhaust gas.
CAUTION
Keep people and combustible mate-
rials away from the exhaust pipe
while the engine is running. The
exhaust gas is very hot.
Do not drive, idle or park your ve-
hicle over anything that might burn
easily such as grass, leaves, paper
or rags.
NOTICE
A large amount of unburned gases
flowing into the threeway catalytic
converter may cause it to overheat
and create a fire hazard. To prevent
this and other damage, observe the
following precautions:
Use only unleaded gasoline.
 Do not drive with an extremely low
fuel level; running out of fuel could
cause the engine to misfire, creat-
ing an excessive load on the three
way catalytic converter.
 Do not allow the engine to run at
idle speed for more than 20 min-
utes.
 Avoid racing the engine.
 Do not pushstart or pullstart your
vehicle.
 Do not turn off the ignition while
the vehicle is moving.
Keep your engine in good running
order. Malfunctions in the engine
electrical system, electronic ignition
system/distributor ignition system
or fuel system could cause an ex-
tremely high threeway catalytic
converter temperature.
 If the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a checkup as soon
as possible. Remember, your Toyota
dealer knows your vehicle and its
threeway catalytic converter sys-
tem best.
 To ensure that the threeway cata-
lytic converter and the entire emis-
sion control system operate proper-
ly, your vehicle must receive the
periodic inspections required by the
Toyota Maintenance Schedule. For
scheduled maintenance information,
refer to the “Scheduled Maintenance
Guide” or “Owner ’s Manual Supple-
ment”.
