This meter displays the odometer and
two trip meters.1. Odometer—It shows the total distance the vehicle has been driven.
2. Two trip meters—Show two different distances independently driven since
the last time each trip meter was set
to zero.
You can use one trip meter to calculate
the fuel economy and the other to
measure the distance on each trip. All
trip meter data is cancelled if the elec-
trical power source is disconnected. 3. Trip meter reset knob—Resets the two
trip meters to zero, and also change
the meter display.
To change the meter display, quickly
push and release the knob. The meter
display changes in the order from the
odometer to trip meter A to trip meter
B, then back to the odometer each
time you push.
To reset the trip meter A to zero, dis-
play the meter A reading, then push
and hold the knob until the meter is
set to zero. The same process can be
applied for resetting the trip meter B.

The system must be reset after the en-
gine oil replacement. Reset the system by
the following procedure:1. Turn the ignition key to the “ACC” or “LOCK” position with the odometer
reading shown. (For details, see
“Odometer and two trip meters” on
page 166 in this Section.)
2. Turn the ignition key to the “ON” posi- tion while holding down the trip meter
reset button.
Hold down the button 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) 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
key is turned to “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 195 in Section 1 −6.
(p) Key Reminder Buzzer
This buzzer reminds you to remove the
key when you open the driver’s door with
the ignition key in the “ACC” or “LOCK”
position. CHECKING SERVICE REMINDER
INDICATORS (except the low fuel level
warning light
and low windshield
washer fluid 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. Turn the ignition key to “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 tire pressure warning
light, dynamic laser cruise master
warning light and engine oil replace-
ment reminder light go off after a few
seconds. The SRS warning light goes
off after about 6 seconds. (“TRAC
OFF”, “READY” (dynamic laser cruise
ready mode) indicator lights and slip
indicator light also comes on and go
off after a few seconds.)
If any service reminder indicator or warn-
ing buzzer does not function as described
above, have it checked by your Toyota
dealer as soon as possible.

Your automatic transmission has a shift
lock system to minimize the possibility of
incorrect operation. This means you can
only shift out of “P” position when the
brake pedal is depressed (with the ignition
switch in “ON” position).
(a) Selector lever
The shift position is also displayed on the
instrument cluster.
P:Parking, engine starting and key
removal
R: Reverse
N: Neutral
D: Normal driving
(shifting into overdrive possible)
4: Engine braking
(shifting into overdrive not possible)
3, 2: Stronger engine braking
L: Maximum engine braking
Automatic transmission
Selector lever
Shift normally. Shift with the brake pedal
depressed. (The ignition switch
must be in “ON” position.)

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 vehicle to vehicle
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.

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 DESIRED SPEED”
on page 201. 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. Follow up 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 203.
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.

When the ignition is turned off, all the
preset data is cleared. When you use the
dynamic laser cruise control again, you
need to reset the data.
CAUTION
To avoid accidentally engaging the
cruise control, keep the “ON OFF”
button off when not using the dynam-
ic laser cruise control.
SETTING THE DESIRED SPEED
The transmission must be in “D” before
you set the cruise control speed.
Bring your vehicle to the desired speed,
push the lever down in the “− SET” direc-
tion and release it. This sets the vehicle
at that speed. At this time, the display
indicates settings such as the preset ve-
hicle speed, whether a vehicle is present
ahead and selected vehicle −to −vehicle dis-
tance. If there is no vehicle detected
ahead, the display does not indicate the
vehicle ahead. You can now take your foot
off the accelerator pedal. If you need to accelerate—for example,
when passing—depress the accelerator
pedal enough for the vehicle to exceed
the preset speed. When you release the
accelerator pedal, the vehicle will return to
the control prior to acceleration.
You cannot set a desired speed if the
master warning light comes on, the alarm
sounds and the display indicates one of
the warning codes “E1”, “E2” or “E3”. If
any of the above codes appears on the
display, see “VEHICLE
−TO −VEHICLE
DISTANCE CONTROL MODE FAILURE
WARNING” on page 206.
CANCELLING THE PRESET SPEED
You can cancel the preset speed by doing
any of the following:
a. Pulling the lever in the “CANCEL” direction.
b. Depressing the brake pedal. c. Pressing the “ON −OFF” button.
If cancelled by a. or b., the “READY”
indicator comes on and the dynamic laser
cruise control enters the ready mode.
If cancelled by c., the “CRUISE” indicator
light goes off in the instrument panel. In
this case, the preset speed data is
cleared, and you must set the speed from
the beginning.
