The SRS airbag and seat belt pretensioner devices in your Toyota contain
explosive chemicals. If the vehicle is scrapped with the airbag s 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 preten sioner
removed and disposed of by a qualified service shop or by your Toyota dealer
before you scrap your vehicle.
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.

WARNING
■ General precautions while driving
Driving under the influence: Never drive your vehicle when unde r 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 judg ment and
reduce coordination, which could lead to an accident that could result in
death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistake s that other
drivers or pedestrians might make and be ready to avoid acciden ts.
Driver distraction: Always give your full attention to driving. Anything that
distracts the driver, such as adjusting controls, talking on a cellular phone or
reading can result in a collision with resulting death or serio us injury to you,
your occupants or others.
■ General precaution regar ding children’s safety
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by p laying with
the windows, the moon roof, or other features of the vehicle. In addition,
heat build-up or extremely cold temperatures inside the vehicle can be fatal
to children.

2964-5. Using the driving support systems
Four-wheel drive system
Use the front-wheel drive control switch to select the following transfer
modes:
“2WD” (high speed position, two-wheel drive)
Use this for normal driving on dry hard-surfaced roads. This po sition
gives greater economy, quietest ride and least wear.
“4H” (high speed position, four-wheel drive)
Use this for driving only on tracks that permit the tires slide, like off-road,
icy or snow-covered roads. This position provides greater traction than
two-wheel drive.
The “4HI” indicator will come on.
“4L” (low speed position, four-wheel drive)
Use this for maximum power and traction. Use “4L” for climbing or
descending steep hills, off-road driving, and hard pulling in s and, mud or
deep snow.
The “4LO” indicator will come on.

Driving
AUTO LSD system
The system can be used on 2WD models and in 2WD mode on 4WD
models. 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 briefly to turn on
the system.
The “AUTO LSD” indicator will
come on.
To turn off the system, press
again.
Stop the vehicle completely, and
press for more than 3 sec-
onds.
The “AUTO LSD” and VSC off
indicators will come on.
To turn off the system, press
again.
The AUTO LSD system aids trac tion by using the traction con-
trol system to control engine performance and braking when
one of the drive wheels begins to spin.
The system should be used only when one of the drive wheels
spinning occurs in a ditch or rough surface.

Driving
Driving assist systems
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenl y,
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 p edal
is depressed when the system de tects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake
pressure for individual wheels and reducing driving torque when
trailer sway is detected
◆TRAC (Traction Control) for 2WD models and 2WD mode on
4WD models
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicl e or accelerating on slippery roads
◆Hill-start assist control
Helps to reduce the backward movement of the vehicle when start -
ing on an uphill
To keep driving safety and perf ormance, the following systems
operate automatically in respon se to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heav ily when operating the vehi-
cle.

Vehicle specifications
This information has been prepared in accordance with regulations
issued by the National Highway Tr affic Safety Administration of the
U.S. Department of Transportation.
It provides the purchasers and/or prospective purchasers of Toyota
vehicles with info rmation on uniform ti re quality grading.
Your Toyota dealer will help answer any questions you may have as
you read this information.
■DOT quality grades
All passenger vehicle tires must conform to Federal Safety Requ ire-
ments in addition to these grades. Quality grades can be found
where applicable on the tire sidewall between tread shoulder an d
maximum section width.
For example: Treadwear 200 Traction AA Temperature A
■Treadwear
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a s peci-
fied government t est course.
For example, a tire graded 150 would wear one and a half (1 - 1 /2)
times as well on the governmen t course as a tire graded 100.
The relative performance of tires depends upon the actual condi -
tions of their use. Performance ma y differ significantly from the norm
due to variations in driving habits, service practices and diff erences
in road characteristics and climate.
Uniform Tire Quality Grading

6189-1. Specifications
■Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C,
and they represent the tire’s ability to stop on wet pavement a s
measured under controlled conditions on specified government te st
surfaces of asphalt and concrete.
A tire marked C may have p oor traction performance.
Warning: The traction grade assigned to this tire is based on b raking
(straight ahead) traction tests and does not include cornering (turn-
ing) traction.
■Temperature A, B, C
The temperature grades are A ( the highest), B, and C, representing
the tire’s resistance to the ge neration of heat and its ability to dissi-
pate heat when tested under contr olled conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can c ause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure.
Grade C corresponds to a level of performance which all passeng er
car tires must meet under the Fe deral Motor Vehicle Safety Stan-
dard No. 109.
Grades B and A represent higher levels of performance on the labo-
ratory test wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is pro perly
inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either sepa-
rately or in combination, can c ause heat buildup and possible t ire
failure.
