GASOLINES CONTAINING DETERGENT ADDITIVES Toyota recommends use of gasolines that contain detergent additives to avoid build−up of engine deposits. For further details, ask your Toyota dealer or a local gasoline retailer. IMPROVED GASOLINES The American Automobile Manufacturers Association (AAMA) has developed a specification of improved gasolines. The AAMA specification offers optimal fuel information for better vehicle perfor- mance and better protection of your en- gine. Toyota recommends the use of gasolines that meet the AAMA specification, if avail- able, for improved driveability and emis- sion control system. GASOLINES CONTAINING MTBE Gasolines that contain MTBE (Methyl Tertiary−Butyl Ether) are available in the market. If you use a gasoline mixed with MTBE, make certain that it does not contain more than 15 % of MTBE. If the use of gasolines containing MTBE causes poor driveability and/or poor fuel economy, you should discontinue the use of fuels containing MTBE.
GASOLINES CONTAINING MMT Some gasolines contain an octane−en- hancing additive called MMT (methylcy- clopentadienyl manganese tricarbonyl). Toyota does not recommend the use of gasolines that contain MMT. If fuels con- taining MMT are used, your emission con- trol system may be adversely affected. The Malfunction Indicator Lamp on the in- strument cluster may come on. If this hap- pens, contact your Toyota dealer for ser- vice. GASOLINES CONTAINING ALCOHOL If you use gasohol in your Toyota, be sure that it is unleaded, has an octane rating no lower than 87 and does not contain more than 10 % ethanol. Gasohol is a mixture of gasoline and etha- nol. Toyota does not recommend the use of gasolines containing methanol. If you use gasoline containing methanol, use only gasoline meeting the requirements above and also containing less than 5 % metha- nol with cosolvents and corrosion inhibi- tors for methanol.
OCTANE RATING Select Octane Rating 87 (Research Octane Number 91) or higher. For improved vehicle performance, the use of premium unleaded gasoline with an Octane Rating of 91 (Research Octane Number 96) or higher is recommended. Use of unleaded gasoline with an octane rating or research octane number lower than stated above will cause persistent heavy knocking. If it is severe, this will lead to engine damage. If your engine knocks... If you detect heavy knocking even when using if you hear steady knocking while holding a steady speed on level roads, consult your Toyota dealer. However, now and then, you may notice light knocking for a short time while accel- erating or driving up hills. This is no need of concern.

Three−way catalytic converter
The three−way catalytic converter is an emission control device installed in the exhaust system. The purpose is to reduce pollutants in the exhaust gas.
CAUTION
D Keep people and combustible mate- rials away from the exhaust pipe while the engine is running. The exhaust gas is very hot.
D Do not drive, idle or park your ve- hicle over anything that might burn easily such as grass, leaves, paper or rags.

Engine exhaust cautions
CAUTION
D Avoid inhaling the engine exhaust. It contains carbon monoxide, which is a colorless and odorless gas. It can cause unconsciousness or even death.
D Make sure the exhaust system has no holes or loose connections. The system should be checked from time to time. If you hit something, or notice a change in the sound of the the system exhaust, have checked immediately.
D Do not run the engine in a garage or enclosed area except the time needed to drive the vehicle in or out. The exhaust gases cannot escape, making this a particularly dangerous situation.
for
D Do not remain for a long time in a parked vehicle with the engine run- ning. If it is unavoidable, however, do so only in an unconfined area and adjust the heating or cooling system to force outside air into the vehicle.
NOTICE
large amount of unburned gases into the three−way catalytic flowing converter may cause it to overheat and create a fire hazard. To prevent this and other damage, observe the following precautions: z Use only unleaded gasoline. z Do not drive with an extremely low fuel level; running out of fuel could cause the engine to misfire, creat- ing an excessive load on the three− way catalytic converter.
z Do not allow the engine to run at idle speed for more than 20 min- utes.
z Avoid racing the engine. z Do not push−start or pull−start your
vehicle.
z Do not turn off the ignition while
the vehicle is moving.
in
z Keep your engine in good running order. Malfunctions the engine electrical system, electronic ignition system/distributor ignition system or fuel system could cause an ex- tremely high three−way catalytic converter temperature.
z If the engine becomes difficult to start or stalls frequently, take your vehicle in for a check−up as soon as possible. Remember, your Toyota dealer knows your vehicle and its three−way catalytic converter sys- tem best.
z To ensure that the three−way cata- lytic converter and the entire emis- sion control system operate proper- ly, your vehicle must receive the periodic inspections required by the Toyota Maintenance Schedule. For scheduled maintenance information, refer the separate ”Owner’s Manual Supplement/Maintenance Schedule”.

Facts about engine oil consumption FUNCTIONS OF ENGINE OIL Engine oil has the primary functions of lubricating and cooling the inside of the engine, and plays a major role in main- taining the engine in proper working order. ENGINE OIL CONSUMPTION It is normal that an engine should con- sume some engine oil during normal engine operation. The causes of oil consumption in a normal engine are as follows. D Oil is used to lubricate pistons, piston rings and cylinders. A thin film of oil is left on the cylinder wall when a pis- ton moves downwards in the cylinder. High negative pressure generated when the vehicle is decelerating sucks some of this oil into the combustion chamber. This oil as well as some part of the oil film left on the cylinder wall is burned by temperature combustion gases during the combustion process. D Oil is also used to lubricate the stems of the intake valves. Some of this oil is sucked into the combustion chamber together with is burned along with the fuel. High tem- perature exhaust gases also burn the oil used to lubricate the exhaust valve stems.

The amount of engine oil consumed de- pends on the viscosity of the oil, the quality of the oil and the conditions the vehicle is driven under. More oil is consumed by high−speed driv- ing and frequent acceleration and decel- eration. A new engine consumes more oil, since its pistons, piston rings and cylinder walls have not become conditioned. When judging the amount of oil con- sumption, note that the oil may become diluted and make it difficult to judge the true level accurately. As an example, if a vehicle is used for repeated short trips, and consumes a nor- mal amount of oil, the dipstick may not show any drop in the oil level at all, even after 1000 km (600 miles) or more. This is because the oil is gradually becoming diluted with fuel or moisture, making it appear that the oil level has not changed. The diluting ingredients evaporate out when the vehicle is then driven at high speeds, as on an express way, making it appear that oil is excessively consumed after driving at high speeds.

IMPORTANCE OF ENGINE OIL LEVEL CHECK One of the most important points in prop- er vehicle maintenance is to keep the en- gine oil at the optimum level so that oil function will not be impaired. Therefore, it is essential that the oil level be checked regularly. Toyota recommends that the oil level be checked every time you refuel the vehicle.

D Even though the anti−lock brake sys- tem is operating, a driver cannot main- tain full control on certain slippery road surfaces, when cornering at high speeds, or in violent maneuvers.
D Avoid high speeds on wet roads. The anti−lock brake system cannot elimi- nate the risk of hydroplaning and loss of tire friction.
in
Always maintain a safe distance from the vehicle front of you. Compared with vehicles not fitted with an anti−lock brake system, your vehicle may require a longer stopping distance in the following cases: D Driving on rough, gravel or snow−cov-
ered roads.
D Driving with tire chains installed. D Driving on roads where the road sur- face is pitted or has other differences in surface height.

Brake pad wear limit indicators
The brake pad wear limit indicators on your disc brakes give a warning noise when the brake pads are worn to where replacement is required. If you hear a squealing or scraping noise while driving, have the brake pads checked and replaced by your Toyota dealer as soon as possible. Expensive ro- tor damage can result if the pads are not replaced when necessary.
”ABS” warning light The light comes on when the ignition key is turned to the ”ON” position. After a few seconds, the light will go off. If either of the following conditions occurs, this indicates a malfunction somewhere in the parts monitored by the warning light system. Contact your Toyota dealer as soon as possible to service the vehicle. D The
light does not come on as de-
scribed above, or remains on.
D The light comes on while driving. Even if the anti−lock brake system should fail, the brake system will still operate conventionally. However, when the ”ABS” warning light is on (and the brake system warning light is off), the anti−lock brake system is not assisting brake performance so lock−up during sudden braking or braking on slippery road surfaces. Have your vehicle checked by your Toyota dealer as soon as pos- sible.

Theft prevention labels
(except for Canada)
Your new vehicle carries theft preven-
tion labels which are approximately 56
mm (2.20 in.) by 16 mm (0.63 in.).
The purpose of these labels is to reduce
the incidence of vehicle thefts by facilitat-
ing the tracing and recovery of parts from
stolen vehicles. The label is designed so
that once it is applied to a surface, any
attempt to remove it will result in destroy-
ing the integrity of the label. Transferring
these labels intact from one part to anoth-
er, will be impossible.
NOTICE
You should not attempt to remove the theft prevention labels as it may vio- late certain state or federal laws.

CAUTION
D Do not mix summer and all season tires on your vehicle as this can cause dangerous handling charac- teristics, resulting in loss of con- trol.
D Do not use tires other than the manufacturer’s designated tires, and never mix tires or wheels of the sizes different from the originally equipped tires and wheels.
Suspension and chassis
CAUTION
Do not modify the suspension/chassis with lift kits, spacers, springs, etc. It can cause dangerous vehicle handling characteristics, resulting loss of control.

Types of tires Determine what kind of tires your ve- hicle is originally equipped with. 1. Summer tires Summer tires are high−speed capability tires best suited to highway driving under dry conditions. Since summer tires do not have the same traction performance as snow tires, sum- mer tires are inadequate for driving on snow−covered or icy roads. For driving on snow−covered or icy roads, we recom- mend using snow tires. If installing snow tires, be sure to replace all four tires. 2. All season tires All season tires are designed to provide better traction in snow and to be adequate for driving in most winter conditions, as well as for use all year round. All season tires, however, do not have adequate traction performance compared with snow tires in heavy or loose snow. Also, all season tires fall short in accel- eration performance compared with summer tires in highway driving.

Tips for driving in various conditions D Always slow down in gusty crosswinds. This will allow you much better control. D Drive slowly onto curbs and, if pos- sible, at a right angle. Avoid driving onto high, sharp−edged objects and other road hazards. Failure to do so can lead to severe tire damage result- ing in tire bursts.
they
D When parking on a hill, turn the front wheels until touch the curb so that the vehicle will not roll. Apply the parking brake, and place the transmis- sion the wheels.
If necessary, block
in ”P”.
D Washing your vehicle or driving through deep water may get the brakes wet. To see whether they are wet, check that there is no traffic near you, and then press the pedal lightly. If you do not feel a normal braking force, the brakes are probably wet. To dry them, drive the vehicle cautiously while lightly pressing the brake pedal with the park- ing brake pulled. If they still do not work safely, pull to the side of the road and call a Toyota dealer for assistance.
NOTICE
z Do not crank for more than 30 se- conds at a time. This may overheat the starter and wiring systems.
z Do not race a cold engine. z If the engine becomes difficult to start or stalls frequently, have the engine checked immediately.
(b) Starting the engine Before starting the engine, be sure to fol- low the instructions in ”(a) Before crank- ing”. Normal starting procedure The multiport fuel injection system/sequen- tial multiport fuel injection system in your engine automatically controls the proper air−fuel mixture for starting. You can start a cold or hot engine as follows: 1. With your foot off the accelerator ped- al, crank the engine by turning the key to ”START”. Release it when the en- gine starts.
2. After the engine runs for about 10 se-
conds, you are ready to drive.
If the weather is below freezing, let the engine warm up for a few minutes before driving. If the engine stalls... Simply restart it, using the correct proce- dure given in normal starting. If the engine will not start— See ”If your vehicle will not start” in Part 4.

Winter driving tips Make sure you have ethylene−glycol an- tifreeze in the radiator.
NOTICE
Do not use alcohol type antifreeze.
Check the condition of the battery and cables. Cold temperatures reduce the capacity of any battery, so it must be in top shape to provide enough power for winter start- ing. Chapter 7−3 tells you how to visually inspect the battery. Your Toyota dealer and most service stations will be pleased to check the level of charge. Make sure the engine oil viscosity is suitable for the cold weather. See Chapter 7−2 for recommended viscos- ity. Leaving a heavy summer oil in your vehicle during winter months may cause harder starting. If you are not sure about which oil to use, call your Toyota deal- er—he will be pleased to help. Keep the door locks from freezing. Squirt lock de−icer or glycerine into the locks to keep them from freezing. To open a frozen lock, try heating the key before inserting it.

Trailer towing Your vehicle is designed primarily as a passenger-and-load-carrying vehicle. Tow- ing a trailer will have an adverse effect on handling, performance, braking, durability and driving economy (fuel consumption, etc.). Your safety and satisfaction depend on the proper use of correct equipment and cautious driving habits. For your safe- ty and the safety of others, you must not overload your vehicle or trailer. Ask your local Toyota dealer for further details be- fore towing. WEIGHT LIMITS Before towing, make sure the total trail- er weight, gross combination weight, gross vehicle weight, gross axle weight and trailer tongue load are all within the limits. The total trailer weight and tongue load can be measured with platform scales found at a highway weighing station, build- ing supply company, trucking company, junk yard, etc.
Use a washer fluid containing an anti- freeze solution. This product is available at your Toyota dealer and most auto parts stores. Follow the manufacturer’s directions for how much to mix with water.
NOTICE
Do not use engine antifreeze or any other substitute because it may dam- age your vehicle’s paint.
Do not use your parking brake when there is a possibility it could freeze. When parking, put the transmission into ”P” and block the rear wheels. Do not use the parking brake, or snow or water accu- mulated in and around the parking brake mechanism may freeze, making it hard to release. Keep ice and snow from accumulating under the fenders. Ice and snow built up under your fenders can make steering difficult. During bad winter driving, stop and check under the fenders occasionally.

trailer
D Toyota recommends removing the trail- er hitch whenever you are not towing to reduce the possibility of additional damage caused by the hitch if your vehicle is struck from behind. After the hitch, seal any mounting holes in the vehicle body to prevent entry of pollutants such as ex- haust fumes, dirt, water, etc.
removing
NOTICE
Do not use axle−mounted hitches as they can cause damage to the axle housing, wheel bearings, wheels or tires. Also, never install a hitch which may interfere with the normal function of an Energy Absorbing Bumper, if so equipped.
BRAKES AND SAFETY CHAINS D Toyota
recommends
trailers with brakes that conform to any applica- ble federal and state/provincial regu- lations.
D A safety chain must always be used between the towing vehicle and the trailer. Leave sufficient slack in the chain for turns. The chain should cross under to prevent the tongue from dropping to the ground in case it becomes dam- aged or separated. For correct safety chain procedures, follow the hitch or trailer manufacturer’s recommenda- tions.
