Vehicle load limits Vehicle load limits include total load capacity, seating capacity, towing ca- pacity and cargo capacity. Follow the load limits shown below. Total load capacity:

538 kg (1185 Ib.) Total load capacity means com- bined weight of occupants, cargo and luggage. Tongue load is in- cluded when trailer towing.

Seating capacity:

7−passenger models— Total 7 (Front 2, Rear 5) 8−passenger models— Total 8 (Front 2, Rear 6) Seating capacity means the maxi- mum number of occupants whose estimated average weight is 68 kg (150 lb.) per person. Depending on the weight of each person, the seat- ing capacity given may exceed the total load capacity.

398

05 SIENNA_U (L/O 0409)

NOTICE

CAUTION

Do not apply the load more than each load limit. That may cause not only damage to the tires, but also deterioration to the steering ability and braking ability, which may cause an accident.

Even if the number of occupants are within the seating capacity, do not exceed the total load ca- pacity.

Towing capacity:

Without towing package

907 kg (2000 Ib.)

With towing package

1587 kg (3500 Ib.) Towing capacity means the maxi- mum gross trailer weight (trailer weight plus its cargo weight) that your vehicle is able to tow.

Cargo capacity Cargo capacity may increase or de- crease depending on the size (weight) and the number of occupants. For de- tails, see “Capacity and distribution” that follows.

Cargo and luggage— —Stowage precautions When stowing cargo and luggage in the vehicle, observe the following: D Put cargo and luggage in the lug- gage compartment when at all possible. Be sure all items are se- cured in place.

D Be careful to keep the vehicle bal- anced. Locating the weight as far forward as possible helps maintain balance.

D For better fuel economy, do not

carry unneeded weight.

CAUTION

D To prevent cargo and luggage from sliding forward during braking, do not stack anything in the luggage compartment higher the seatbacks. Keep cargo and luggage low, as close to the floor as pos- sible.

than

D Never allow anyone to ride in the luggage compartment. It is not designed for passengers. They should ride in their seats with their seat belts properly fastened. Otherwise, they are much more likely to suffer seri- ous bodily injury, in the event of sudden braking or a colli- sion.

D Do not drive with objects left on top of the instrument panel. They may interfere with the driver’s field of view. Or they may move during sharp vehicle acceleration or turning, and im- pair the driver’s control of the vehicle. In an accident they may injure the vehicle occu- pants.

FOR

—Capacity and distribution Cargo capacity depends on the to- tal weight of the occupants. (Cargo capacity) = (Total load capac- ity) – (Total weight of occupants) STEPS CORRECT LOAD LIMIT 1. Locate the statement “The com- bined weight of occupants and cargo should never exceed XXX pounds” on your vehicle’s placard. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.

DETERMINING

3. Subtract the combined weight of the driver and passengers from XXX kilograms or XXX pounds. 4. The resulting figure equals the available amount of cargo and lug- gage load capacity. For example, if the “XXX” amount equals 1400
lbs. and there will be five 150 lb. passengers in your vehicle, the amount of available cargo and lug- gage load capacity is 650 lbs. (1400–750 (5x150)=650 lbs).

399

2005 SIENNA from Sep. ’04 Prod. (OM45431U)

05 SIENNA_U (L/O 0409)

372 kg – 176 kg = 196 kg. (819 lb. – 388 lb. = 431 lb.) As shown in the above example, if the number of occupants increases, the cargo and luggage load equaling the combined weight of occupants who got on later must be reduced. In other words, if the increase in the number of occupants causes the excess of the total load capacity (combined weight of occupants plus cargo and luggage load), you have to reduce the cargo and luggage on your vehicle. For details about total load capacity, see “Vehicle load limits” on page 398.

5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4.

6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available car- go and luggage load capacity of your vehicle.

For details about trailer towing, see page 408.

EXAMPLE ON YOUR VEHICLE In case that 2 people with the com- bined weight of 166 kg (366 lb.) are riding in your vehicle with the total load capacity of 538 kg (1185 lb.), the available amount of cargo and lug- gage load capacity will be as follows: 538 kg – 166 kg = 372 kg. (1185 lb. – 366 lb. = 819 lb.) From this condition, if 3 more passen- gers with the combined weight of 176
kg (388 lb.) get on, the available car- go and luggage load will be reduced as follows:

CAUTION

Even if the total load of occu- pant’s weight and the cargo load is less than the total load capac- ity, do not apply the load uneven- ly. That may cause not only dam- age to the tire but also deteriora- tion to the steering ability due to unbalance of the vehicle, causing an accident.

Types of tires Determine what kind of tires your vehicle is originally equipped with. 1. Summer tires Summer tires are high−speed capabil- ity tires best suited to highway driving under dry conditions. Since summer tires do not have the same traction performance as snow tires, summer tires are inadequate for driving on snow−covered or icy roads. For driving on snow−covered or icy roads, we recommend using snow tires. If installing snow tires, be sure to replace all four tires. 2. All season tires All season tires are designed to pro- vide better traction in snow and to be adequate for driving in most winter conditions, as well as for use all year round.

traction

All season tires, however, do not have adequate performance compared with snow tires in heavy or loose snow. Also, all season tires fall short in acceleration and handling performance compared with summer tires in highway driving. The details about how to distinguish summer tires from all season tires are described on page 388.

CAUTION

D Do not mix summer and all sea- son tires on your vehicle as this can cause dangerous han- dling characteristics, resulting in loss of control.

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.

z Do not race a cold engine. z If the engine becomes difficult to start or stalls frequently, have the engine checked immediately.

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 such as a tire burst. Drive slowly when passing over bumps or travelling on a bumpy road. Other- wise, the impact could cause severe damage to the tires and/or wheels.

Winter driving tips Make sure your coolant is properly pro- tected against freezing. Only use “Toyota Super Long Life Coolant” or similar high quality ethylene glycol based non−silicate, non−amine, non−nitrite, and non−borate coolant with long−life technology. (Coolant hybrid organic acid with acid technology low phosphates and organic acids.) See “Checking the engine coolant level” on page 468 in Section 7−2 for details of coolant type selection. For the U.S.A.—“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized water. This coolant pro- vides protection down to about −35_C (−31_F). For Canada—“Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water. This coolant pro- vides protection down to about −42_C (−44_F).

NOTICE

Do not use plain water alone.

05 SIENNA_U (L/O 0409)

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. Section 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 page 466 in Section 7−2 for recom- mended viscosity. Leaving a heavy sum- mer oil in your vehicle during winter months may cause harder starting. If you are not sure about which oil to use, call your Toyota dealer—they 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. 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. Depending on where you are driving, we recommend you carry some emer- gency equipment. Some of the things you might put in the vehicle are tire chains, window scraper, bag of sand or salt, flares, small shovel, jumper cables, etc.

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.

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.

D Check that your rear view mirrors con- form to any applicable federal, state/ provincial or local regulations. If not, install the rear view mirrors required for towing purpose.

TRAILER TOWING TIPS When towing a trailer, your vehicle will handle differently than when not tow- ing. The three main causes of vehicle− trailer accidents are driver error, exces- sive speed and improper trailer loading. Keep these in mind when towing: D Before starting out, check operation of the lights and all vehicle−trailer connec- tions. After driving a short distance, stop and recheck the lights and con- nections. Before actually towing a trail- er, practice turning, stopping and back- ing with a trailer in an area away from traffic until you learn the feel.

D Backing with a trailer is difficult and requires practice. Grip the bottom of the steering wheel and move your hand to the left to move the trailer to the left. Move your hand to the right to move the trailer to the right. (This pro- cedure that when backing without a trailer.) Also, just turn the steering wheel a little at time, avoiding sharp or prolonged turning. Have someone guide you when backing to reduce the risk of an acci- dent.

D Because stopping distance may be in- vehicle−to−vehicle distance creased, should be towing a trailer. For each 16 km/h (10 mph) of speed, allow at least one vehicle and trailer length between you and the ve- hicle ahead. Avoid sudden braking as you may skid, resulting in jackknifing and loss of control. This is especially true on wet or slippery surfaces.

D Avoid jerky starts or sudden accelera-

tion.

D Avoid jerky steering and sharp turns. The trailer could hit your vehicle in a tight turn. Slow down before making a turn to avoid the necessity of sudden braking.

D Remember that when making a turn, the trailer wheels will be closer than the vehicle wheels to the inside of the turn. Therefore, compensate for this by making a turning radius with your vehicle.

D Crosswinds and rough roads will ad- versely affect handling of your vehicle and trailer, causing sway. Pay attention to the rear from time to time to pre- pare yourself for being passed by large trucks or buses, which may cause your vehicle and trailer to sway. If swaying happens, firmly grip the steering wheel and immediately but gradually. Never increase speed. Steer straight ahead. If you make no extreme correction with the steering or brakes, the vehicle and trailer will stabilize.

reduce speed

D Be careful when passing other ve- hicles. Passing requires considerable distance. After passing a vehicle, do not forget the length of your trailer and be sure you have plenty of room be- fore changing lanes.

D In order to maintain engine braking effi- ciency, do not place the transmission in “D”.

How to save fuel and make your vehicle last longer Improving fuel economy is easy—just take it easy. It will help make your vehicle last longer, too. Here are some specific tips on how to save money on both fuel and repairs: D Keep your tires inflated at the cor- rect pressure. Underinflation causes tire wear and wastes fuel. See page 471 in Section 7−2 for instructions. D Do not carry unneeded weight

in your vehicle. Excess weight puts a heavier the engine, causing greater fuel consumption.

D Avoid lengthy warm−up idling. Once the engine is running smoothly, begin driving—but gently. Remember, howev- er, that on cold winter days this may take a little longer.

D Put the selector lever into the “D” when engine braking is not required. Driving with the selector lever in “4” will reduce the fuel economy. (For de- tails, see “Automatic transmission” on page 187 in Section 1−7.) and

in proper alignment. Avoid hitting the curb and slow down on rough roads. Improper alignment not only causes faster tire wear but also puts an extra load on the engine, which, in turn, wastes fuel. D Keep the bottom of your vehicle free from mud, etc. This not only lessens weight but also helps prevent corro- sion.

D Keep your vehicle tuned−up and in top shape. A dirty air cleaner, improp- er valve clearance, dirty plugs, dirty oil and grease, brakes not adjusted, etc. all lower engine performance and con- tribute to poor fuel economy. For longer life of all parts and lower operating costs, keep all maintenance work on schedule, and if you often drive under severe conditions, see that your vehicle frequent maintenance. receives more (For scheduled maintenance informa- tion, please refer the “Scheduled Maintenance Guide” or “Owner’s Manu- al Supplement”.)

D Avoid long engine idling. If you have a long wait and you are not in traffic, it is better to turn off the engine and start again later.

D Avoid engine

lugging or over−rev- ving. Use a gear position suitable for the road on which you are travelling.

D Avoid continuous speeding up and slowing down. Stop−and−go driving wastes fuel.

D Avoid unnecessary stopping and braking. Maintain a steady pace. Try to time the traffic signals so you only need to stop as little as possible or take advantage of through streets to avoid traffic lights. Keep a proper dis- tance from other vehicles to avoid sud- den braking. This will also reduce wear on your brakes.

D Avoid heavy traffic or traffic

whenever possible.

D The gas normally produced by a battery will explode if a flame or spark is brought near. Use only standardized jumper cables and do not smoke or light a match while jump starting.

NOTICE

The battery used for boosting must be 12 V. Do not jump start unless you are sure that the booster battery is correct.

(c) Jump starting To avoid serious personal injury and damage to your vehicle which might re- sult from battery explosion, acid burns, electrical burns, or damaged electronic components, these instructions must be followed precisely. If you are unsure about how to follow this procedure, we strongly that you seek the help of a competent me- chanic or towing service.

CAUTION

D Batteries

contain

sulfuric

acid which is poisonous and corrosive. Wear protective safety glasses when jump starting, and avoid spilling acid on your skin, clothing, or ve- hicle.

D If you should accidentally get acid on yourself or in your eyes, remove any contaminated clothing and flush the affected area with water imme- diately. Then get immediate medical attention. If possible, continue to apply water with a sponge or cloth while en route to the medical office.

JUMP STARTING PROCEDURE 1. If

the booster battery

is

installed in another vehicle, make sure the vehicles are not touching. Turn off all unneces- sary lights and accessories. When boosting, use the battery of matching or higher quality. Any other battery may be difficult to jump start with. If jump starting is difficult, charge the battery for several minutes.

2. If required, remove all the vent plugs from the booster and discharged batter- ies. Lay a cloth over the open vents on the batteries. (This helps reduce the explosion hazard, personal injuries and burns.)

3. If the engine in the vehicle with the booster battery is not running, start it and let it run for a few minutes. During jump starting, run the engine at about 2000 rpm with the accelerator pedal lightly depressed.

the

Some vehicles are equipped with run−flat (RFT) tires. The run−flat tire allows you to continue driving for up to 160 km (100 miles) at a speed below 90 km/h (55 mph) even if any tire goes flat. However, in some conditions (such as high temperatures), you could not con- tinue driving for up to 160 km (100
miles). When the tire goes flat or when the tire pressure is below 100 kPa (1.0
kgf/cm2 or bar, 15 psi), the tire must be replaced. If you are not sure, consult your Toyota dealer. Do not use the repaired tire.

distinctive

Compact spare tire The compact spare tire is designed for temporary emergency use only. The compact spare tire is identified by wording “TEMPORARY USE ONLY” molded into the side wall of the tire. The compact spare tire saves space in your luggage compartment, and its lighter weight helps to improve fuel economy and permits easier installa- tion in case of a flat tire.

05 SIENNA_U (L/O 0409)

The compact spare tire can be used many times, if necessary. It has tread life of up to 4800 km (3000 miles) de- pending on road conditions and your driving habits. When tread wear indi- cators appear on the tire, replace the tire. See also the tire information on page 471 in Section 7−2 for details on the tread wear indicators and other ser- vice information.

CAUTION

D The compact spare tire was de- signed especially for your To- yota. Do not use it on any other vehicle.

D Do not use more than one com- pact spare tire at the same time.

D The pressure for the compact spare tire must be 420 kPa (4.2
kgf/cm2 or bar, 60 psi).

D Do not exceed 80 km/h (50
mph) when driving with the compact spare tire.

D Replace the compact spare tire with the standard tire as soon as possible.

D Avoid sudden acceleration, sudden deceleration and sharp turns with the compact spare tire.

NOTICE

Your ground clearance is re- duced when the compact spare tire is installed so avoid driving over obstacles and drive slowly on rough, unpaved roads and speed bumps. Also, do not at- tempt to go through an auto- matic car wash as the vehicle may get caught, resulting in damage.
