Scrapping of 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 preten sioner
removed and disposed of by a qualified service shop or by your To y o t a
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
components may include airbag, seat belt pretensioners, and wir eless
remote control 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 ope rate 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 dis-
tracts the driver, such as adjusting controls, talking on a cel lular phone or
reading can result in a collision with resulting death or serio us injury to you,
your occupants or others.
■ General precaution regarding 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 or other features of the vehicle. In addition, heat build-up or
extremely cold temperatures inside the vehicle can be fatal to children.

When driving
Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in response 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 suddenl y, o r i f
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)
Helps to maintain drive power and prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery road s.
The TRAC system is also equipped with the brake LSD function.
■ Hill-start assist control

P. 252
■EPS (Electric Po wer Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel

When driving
Tire chains
Tire chains cannot be used on your vehicle because of the lack of
clearance between the tires and vehicle body.
When tire chains cannot be used, use of another type of tractio n
device (such as spring chains) may be acceptable if use on your vehi-
cle is recommended by the device manufacturer, taking into acco unt
tire size and road conditions.
Follow the device manufacturer's instructions, especially regarding
maximum vehicle speed.
To help avoid damage to your vehicle, drive slowly, readjust or
remove the device if it is contacting your vehicle, and do not spin your
wheels. Damage caused to your veh icle by use of a traction device is
not covered under warranty.
Make certain that any traction device you use is an SAE class “ S”
device, and use it on the rear wheels only.
Always use the utmost care when driving with a traction device. Over-
confidence because you are using a traction device could easily lead
to a serious accident.
Selecting tire chains
We recommend that you consult your Toyota dealer for informatio n
about the chains t hat you can use.

Maintenance and care
NOTICE
■
Cleaning the exterior lights
●Wash carefully. Do not use organic substances or scrub with a h ard brush.
This may damage the surfaces of the lights.
● Do not apply wax on the surfaces of the lights.
Wax may cause damage to the lenses.
■ To prevent damage to th e windshield wiper arms
When lifting the wiper arms away from the windshield, pull the driver side
wiper arm upward first, and repeat for the passenger side. When returning
the wipers to their original position, do so from the passenger side first.
■ When using a high pressure car wash
Do not bring the nozzle tip close to boots (rubber or resin man ufactured
cover), connectors or the following parts. The parts may be damaged if they
come into contact with high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts

348 4-3. Do-it-yourself maintenance
■Maximum load of tire
Check that the maximum load of the replacement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAWR) of either the front axle or the
rear axle, whichever is greater.
■Tire types
1 Summer tires
Summer tires are high-speed performance tires best suited to hi ghway
driving under dry conditions. Since summer tires do not have th e same
traction performance as snow tires, summer tires are inadequate for
driving on snow-covered or icy roads. For driving on snow-cover ed
roads or icy roads, the use of snow tires is recommended. When
installing snow tires, be sure to replace all four tires.
2 All season tires
All season tires are designed to provide better traction in sno w and to
be adequate for driving in most winter conditions, as well as f or use
year round. All season tires, however, do not have adequate tra ction
performance compared with snow tires in heavy or loose snow. Al so,
all season tires fall short in acceleration and handling perfor mance
compared with summer tires in highway driving.
3Snow tires For driving on snow-covered roads or icy roads, we recommend us ing
snow tires. If you need snow tires, select tires of the same si ze, con-
struction and load capacity as th e originally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tir es without
first checking local regulations for possible restriction. Snow tires
should be installed on all wheels. ( P. 261)
For the GAWR, see the Certification
Label. For the maximum load of the
tire, see the load limit at maximum cold
tire inflation pressure mentioned on the
sidewall of the tire. ( P. 4 7 4 )

5-2. Steps to take in an emergency
If the vehicle becomes stuck
■When it is difficult to free the vehicle
Carry out the following procedur es if the tires spin or the vehicle
becomes stuck in mud, dirt, or snow:
Stop the engine. Set the parki ng brake and shift the shift
lever to P (vehicles with an automatic transmission) or N
(vehicles with a manual transmission).
Remove the mud, snow or sand from around the rear
wheels.
Place wood, stones or some other material under the rear
wheels to help provide traction.
Restart the engine.
Shift the shift lever to the D or R position (vehicles with an
automatic transmission) or 1 or R position (vehicles with a
manual transmission) and release the parking brake. Then,
while exercising caution, depr ess the accelerator pedal.STEP 1

Uniform Tire Quality GradingThis information has been prepared in accordance with regulations
issued by the National Highway Traffic Safety Administration of the
U.S. Department of Transportation.
It provides the purchasers and/or prospective purchasers of Toyota
vehicles with information on uniform tire 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
Requirements in addition to these grades. Quality grades can be
found where applicable on the tire sidewall between tread shoul der
and maximum se ction 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 speci-
fied government test 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 may differ significantly from the nor m due
to variations in driving habits, service practices and differen ces in
road characterist ics 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 ability to stop on wet pavement a s
measured under controlled cond itions on specified government
test 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, represent -
ing the tire’s resistance to the generation of heat and its abi lity to
dissipate heat when tested under controlled conditions on a speci-
fied 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 Standard
No. 109.
Grades B and A represent higher levels of performance on the la bo-
ratory test wheel than the minimum required by law.
