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.
The vehicle stability control system is acti-
vated 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 526 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.
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 engine switch is turned
to “ON”. If the indicator light does not
come on when the engine switch is turned
on, contact your Toyota dealer.

The tire pressure warning light comes on
when the engine switch is in “ON” position
and goes off after a few seconds. This
means the tire pressure warning system is
operating properly. If the tire inflation pres-
sure becomes low, the light comes on
again. In this case, adjusting the tire infla-
tion pressure will turn off the light after
several minutes. If the light comes on
after blinking for 1 minute, the tire pres-
sure warning system is not working prop-
erly.Indicator

CAUTION
If the tire pressure warning light
comes on, be sure to observe the
following precautions. Failure to do
so could cause loss of vehicle control
and result in death or serious injury.
Vehicles with runflat tires:
Decelerate to the lowest appropriate
speed as soon as possible. Do not
drive over 90 km/h (55 mph).
Check and adjust the tire inflation
pressure immediately.
If the tire pressure warning light
comes on even after tire inflation
pressure adjustment, it is probable
that you have a flat tire. Have the
tire replaced by the nearest Toyota
dealer.
Avoid abrupt maneuvering and brak-
ing. If the vehicle tires deteriorate,
you could lose control of the steer-
ing wheel or the brakes.
Vehicles with standard tires:
Stop your vehicle in a safe place as
soon as possible. Adjust the tire
inflation pressure immediately.
If the tire pressure warning light
comes on even after tire inflation
pressure adjustment, it is probable
that you have a flat tire. Check the
tires. If the tire is flat, change to
the spare tire and have the flat tire
repaired by the nearest Toyota deal-
er.
Avoid abrupt maneuvering and bra-
king. If the vehicle tires deteriorate,
you could lose control of the steer-
ing wheel or the brakes.

If the tire pressure warning light does not
blink slowly three times when you push
and hold the tire pressure warning reset
switch, initialization has failed and the tire
pressure warning system may not work
properly. In this case, initialize the system
again. If initialization cannot be performed,
have the system checked at your Toyota
dealer.
CAUTION
Do not push the tire pressure warn-
ing reset switch without first adjust-
ing the tire inflation pressure to the
specified level. Otherwise, the tire
pressure warning light may not come
on even if the tire inflation pressure
is low, or it may come on when the
tire inflation pressure is actually nor-
mal.

When parking, firmly apply the parking
brake to avoid inadvertent creeping.
To set: Fully depress the parking brake
pedal. For better holding power, first de-
press the brake pedal and hold it while
setting the parking brake.
To release: Depress the parking brake
pedal once again.
To remind you that the parking brake is
set, the parking brake reminder light in
the instrument panel remains on until you
release the parking brake.
The buzzer will remind you to release the
parking brake when the vehicle speed
rises above 5 km/h (3 mph) with the park-
ing brake is applied.
CAUTION
Before driving, be sure the parking
brake is fully released and the park-
ing brake reminder light is off.
The cruise control is designed to main-
tain a set cruising speed without requir-
ing the driver to operate the accelera-
tor. Cruising speed can be set to any
speed above 40 km/h (25 mph).
Within the limits of the engine’s capabili-
ties, cruising speed can be maintained up
or down grades. However, changes in ve-
hicle speed may occur on steeper grades.
CAUTION
To help maintain maximum control
of your vehicle, do not use the
cruise control when driving in
heavy or varying traffic, or on slip-
pery (rainy, icy or snowcovered) or
winding roads.
Be careful about vehicle speed as
it may increase when driving down-
hill with the cruise control on.
TURNING THE SYSTEM ON AND OFF
To turn the cruise control on, press the
“ON−OFF” button. The “CRUISE” indicator
light on the instrument panel will come on
to indicate that the cruise control is opera-
tional. Pressing the “ON −OFF” button
again turns the system off.
When the system is turned off, cruising
speed must be reset when the cruise con-
trol is turned on again.
When the engine switch is turned off, the
system is also automatically turned off. To
use cruise control again, press the “ON −
OFF” button again to turn it on.

CAUTION
To avoid accidentally engaging the
cruise control, turn the system off
when it is not in use. Make sure the
“CRUISE” indicator light is off.
SETTING THE CRUISING SPEED
The transmission must be in “D” or “4”
before you set the cruising 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. If the speed is not satisfac-
tory, tap the lever up for a faster speed,
or tap it down for a slower speed. Each
tap changes the set speed by 1.6 km/h
(1.0 mph). You can now take your foot off
the accelerator pedal. If you need acceleration—for example,
when passing—depress the accelerator
pedal enough for the vehicle to exceed
the set speed. When you release it, the
vehicle will return to the speed set prior
to the acceleration.
CANCELLING THE CRUISE CONTROL
The cruise control may be temporarily
cancelled by the driver or by the system
itself under certain circumstances. Tempo-
rary cancellation allows the set cruising
speed to remain in memory.
The cruise control can be temporarily can-
celled by doing the following:
Pulling the lever in the “CANCEL” di-
rection and releasing it
Depressing the brake pedal
Under certain circumstances, the cruise
control is temporarily cancelled:
When vehicle speed falls below 40
km/h (25 mph)
When vehicle stability control is acti-
vated
When vehicle speed drops 16 km/h (10
mph) below the set speed, the cruise con-
trol is cancelled and the set speed is
erased from memory.

The “CRUISE” indicator light remains on
to indicate that the system is still in op-
eration.
To turn the cruise control off, press the
“ON−OFF” button. Make sure the
“CRUISE” indicator light is off.
If the cruise control automatically cancels
out other than for the above cases, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity.
RESUMING THE CRUISE CONTROL
If the cruise control is temporarily can-
celled, the cruising speed can be resumed
by pushing the lever up in the “+ RES”
direction.
Vehicle speed must be above 40 km/h (25
mph).
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.
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.
However, a faster way to reset is to de-
press the brake pedal and then push the
lever down in the “− SET” direction.
Even if you downshift from “D” to “4”, with
the cruise control on, engine braking will
not be enabled because the cruise control
is not cancelled. To decrease the vehicle
speed, reset to a slower speed with the
cruise control lever or depress the brake
pedal. If you use the brake pedal, cruise
control is cancelled. 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
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 CRUISING SPEED”
on page 231. 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. Followup 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 233.
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.

This system operates by detecting pri-
marily the reflectors of the vehicle
ahead. The distance may not be accu-
rately or absolutely detected in the fol-
lowing cases:
The vehicle ahead has higher ground
clearance, which means that the
placement of the reflectors is in a
higher position.
The rear section of the vehicle ahead
is extremely dirty.
The vehicle ahead or other vehicles
around you are flinging up water or
snow.
Excessive exhaust gas (black smoke)
is coming from the vehicle ahead or
other vehicles around you, obscuring
your front view.
There is an obstruction (protective
film, sticker, etc.) on the reflectors
on the vehicle ahead, or reflectors
are not installed on the vehicle
ahead or are damaged.
Heavy luggage in the luggage
compartment or rear seats is caus-
ing the nose of your vehicle to tilt
up.
CAUTION
To avoid accidents, always keep the
laser radar sensor glass clean and
never allow it to be covered with
icicle or any substance, so it can de-
tect the vehicle in front. (See “LASER
RADAR SENSOR” on page 235.)
CAUTION
Do not rely excessively on dynamic
laser cruise control. Observe the fol-
lowing precautions in order to avoid
serious injury or death:
Under certain conditions where the
vehicle in front slows drastically, or
is stopped, the dynamic laser cruise
control will neither warn you nor
decelerate. You must depress the
brake pedal to slow down, ensuring
collision avoidance or that suffi-
cient vehicletovehicle distance is
maintained.
Do not use dynamic laser cruise
control in the following conditions:
In bad weather (such as rain, fog,
snow, sandstorms or direct sun-
light, or when raindrops or snow-
flakes get on the laser radar sensor
glass), the vehicletovehicle dis-
tance will not be measured accura-
tely.
When using the windshield wipers
at high or low speeds the dynamic
laser radar cruise control turns off.
