Scrapping your Toyota
The SRS airbag and seat belt pretensioner devices in your Toyota contain
explosive chemicals. If the vehicle is scrapped with the airbags and seat belt
pretensioners left as they are, this may cause an accident such as fire. Be
sure to have the systems of the SRS airbag and seat belt pretensioner
removed and disposed of by a qualified service shop or by your Toyota
dealer before you scrap your vehicle.
Perchlorate Material
Special handling may apply,
See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These compo-
nents may include airbag, seat belt pretensioners, and wireless remote con-
trol batteries.
CAUTION
■General precautions while driving
Driving under the influence: Never drive your vehicle when under the influ-
ence of alcohol or drugs that have impaired your ability to operate your vehi-
cle. Alcohol and certain drugs delay reaction time, impair judgment and
reduce coordination, which could lead to an accident that will hurt or kill you,
your occupants or others.
Defensive driving: Always drive defensively. Anticipate mistakes that other
drivers or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that dis-
tracts the driver, such as adjusting controls, talking on a cellular phone or
reading can result in a collision with resulting death or serious injury to you,
your occupants or others.

2-4. Using other driving systems
Four-wheel drive system (if equipped)
Use the front wheel drive control switch to select the following trans-
fer modes.
*1: Vehicles with multi-information display
*2: Vehicles without multi-information display
2WD (high speed position, two-wheel drive)
Normal driving.
4H (high speed position, four-wheel drive)
Greater traction than two wheel drive.
When you experience a loss of power, such as wheel slipping.
The 4HI indicator comes on.
4L (low speed position, four-wheel drive)
Driving requiring maximum power and traction such as climbing or
descending steep hills, off-road driving and hard pulling in sand or mud,
etc.
The 4LO indicator comes on.

When driving
AUTO LSD system
The AUTO LSD system aids traction by using the traction control
system to control engine performance and braking when one of the
rear wheels begins to spin.
The system can be used on 2WD models and in 2WD mode on 4WD
models.
The system should be used only wh en one of the rear wheels spin-
ning occurs in a ditch or rough surface.
The system is activated when driving at a speed under 62 mph (100
km/h).
The AUTO LSD system will be
activated with the following
two procedures.
● Press the VSC OFF switch
briefly.
At this time, the slip and AUTO
LSD indicators will come on.
●Stop the vehicle com-
pletely, and press the VSC
OFF switch for more than 3
seconds.
At this time, the slip, VSC OFF
and AUTO LSD indicators will
come on simultaneously.
To turn off the system, push
the switch again.

When driving
Driving assist systems
When VSC/TRAC/A-TRAC are operatingIf the vehicle is in danger of slip-
ping, or if the rear wheels (2WD
models) or all wheels (4WD
models) spin, the slip indicator
flashes to indicate that VSC/
TRAC/A-TRAC have been
engaged.
A buzzer (intermittent) sounds to
indicate that VSC is operating.
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavi ly when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface.
■Brake Assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
■TRAC (Traction Control) for 2WD
Maintains drive power and prevents the rear wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■A-TRAC (Active Traction Control) for 4WD
Maintains drive power and prevents the all wheels from spinning when
starting the vehicle or accelerating on slippery roads.

Vehicle specifications
■
Treadwear
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested und er controlled conditions on a
specified government test course.
For example, a tire graded 150 would wear one and a half (1 - 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual conditions
of their use, however, and may depart significantly from the norm due
to variations in driving habits, service practices and differences in
road characteristics and climate.
■ Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C,
and they represent the tire’s ab ility to stop on wet pavement as
measured under controlled cond itions on specified government
test surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking
(straight ahead) traction tests and does not include cornering
(turning) traction.
■ Temperature A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of heat and its
ability to dissipate heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure.
The grade C corresponds to a level of performance which all
passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109.
Grades B and A represent higher levels of performance on the
laboratory test wheel than the minimum required by law.
