■Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the follow-
ing situations, oil consumption may increase, and engine oil ma y need to be
refilled in between oil maintenance intervals.
● When the engine is new, for example directly after purchasing the vehicle
or after replacing the engine
● If low quality oil or oil of an inappropriate viscosity is used
● When driving at high engine speeds or with a heavy load, or whe n driving
while accelerating or decelerating frequently
● When leaving the engine idling for a long time, or when driving frequently
through heavy traffic
WARNING
■Used engine oil
●Used engine oil contains potentially harmful contaminants which may
cause skin disorders such as inflammation or skin cancer, so ca re should

5-1. Essential information
If your vehicle needs to be towed
Before towingThe following may indicate a problem with your transmission. Co ntact
your Toyota dealer before towing.
● The engine is running, but t he vehicle will not move.
● The vehicle makes an abnormal sound.
Emergency towing
If a tow truck is not available in an emergency, your vehicle m ay be
temporarily towed using a cable or chain secured to the emergen cy
towing eyelet. This should only be attempted on hard surfaced r oads
for short distances at low speeds.
A driver must be in the vehicle to steer and operate the brakes . The
vehicle’s wheels, drive train, axles, steering and brakes must be in
good condition.
For vehicles with an automatic transmission, only the front towing
eyelet may be used.
If towing is necessary, we recommend having your vehicle towed by
your Toyota dealer or a commerci al towing service, using a lift-type
truck or a flat bed truck.
Use a safety chain system for all towing, and abide by all stat e/pro-
vincial and local laws.
If towing from the rear, the vehicle's front wheels and axles m ust be
in good condition. ( P. 391)
If they are damaged, use a to wing dolly or flat bed truck.

434 5-2. Steps to take in an emergency
NOTICE
■Do not drive the vehicle with a flat tire.
Do not continue driving with a flat tire.
Driving even a short distance wi th a flat tire can damage the tire and the
wheel beyond repair.
■Be careful when driving over bumps with the compact spare tire
installed on the vehicle.
The vehicle becomes lower when d riving with the compact spare tire
compared to when driving with standard tires. Be careful when d riving
over uneven road surfaces.
■Driving with tire chains and the compact spare tire
Do not fit tire chains to the compact spare tire.
Tire chains may damage the vehicle body and adversely affect dr iving
performance.
■When replacing the tires
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact yo ur Toyota dealer as the tire pressure
warning valve and transmitter ma y be damaged if not handled correctly.
■To avoid damage to the tire pressure warning valves and transmi t-
ters
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sea lant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replace the tire pressure warning val ve and
transmitter when replacing the tire. ( P. 3 4 6 )
■Stowing the jack
When stowing the jack in the jack holder, make sure that the pa rt that the
jack handle attaches to is pointing towards the inside of the t runk. Failure
to do so may damage the vehicle body.

Gasoline quality
In very few cases, driveability problems may be caused by the b rand of gas-
oline you are using. If driveability problems persist, try chan ging the brand of
gasoline. If this does not correct the problem, consult your Toyota dealer.
■ Fuel octane rating
This octane rating is the average of the Research Octane and Mo tor Octane
numbers and is commonly referred to as the Anti Knock Index.
Using a gasoline with a lower octane rating can cause persistent and heavy
knocking, which can damage the engine. Do not be concerned if y our vehi-
cle sometimes knocks lightly when you drive up a hill or when y ou acceler-
ate. Contact your Toyota dealer if you use a fuel with the spec ified octane
rating and your vehicle knocks heavily or persistently.
■ Gasoline for California-certified LEV
If your vehicle was certified to California’s low emission vehi cle (LEV) stan-
dards as indicated on the underhood tune-up label, it is design ed to optimize
engine and emission performance with gasoline that meets the cl ean burn-
ing low-sulfur California gasoline specifications. If you live in any other state
than California, your vehicle will operate on gasoline meeting Federal speci-
fications. Gasoline sold outside California is permitted to have higher sulfur
levels, which may affect the performance of your vehicle’s cata lytic converter
and may produce a sulfur exhaust odor or smell. Toyota recommends that
you try a different brand of unleaded gasoline having lower sul fur to deter-
mine if the problem is fuel related before returning your vehic le to an autho-
rized dealer for service.

Toyota does not recommend gasoline containing MMT
Some gasoline contains octane enhancing additive called MMT (Me thylcy-
clopentadienyl Manganese Tricarbonyl).
Toyota DOES NOT recommend the use of gasoline that contains MMT . If
fuel containing MMT is used, your emission control system may b e
adversely affected.
The malfunction indicator lamp on the instrument cluster may co me on. If
this happens, contact your Toyota dealer for service.
NOTICE
■ Notice on fuel quality
●Do not use improper fuels. If improper fuels are used the engin e will be
damaged.
● Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way ca talytic
converters causing the emission control system to malfunction.
● Do not use gasohol other than the type previously stated.
Other gasohol may cause fuel system damage or vehicle performan ce
problems.
● Using unleaded gasoline with an octane number or rating lower t han the
level previously stated may cause persistent heavy knocking.
At worst, this may lead to engine damage and will void the vehicle war-
ranty.
■ Fuel-related poor driveability
If after using a different type of fuel, poor driveability is e ncountered (poor
hot starting, vaporization, engine knocking, etc.), discontinue the use of that
type of fuel.
■ When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle's pa int.

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.
