5-2. Steps to take in an emergency

■Starting the engine when the battery is discharged

The engine cannot be started by push-starting.

■To prevent battery discharge

●Turn off the headlights and the audio system while the engine is off. ●Turn off any unnecessary electrical components when the vehicle is run-

ning at a low speed for an extended period, such as in heavy traffic.

■When the battery is removed or discharged

●The power sliding door (if equipped) must be initialized. (→P. 67) ●The power back door (if equipped) must be initialized. (→P. 82) ●The moon roof (if equipped) must be initialized. (→P. 150)

■Charging the battery

The electricity stored in the battery will discharge gradually even when the vehicle is not in use, due to natural discharge and the draining effects of cer- tain electrical appliances. If the vehicle is left for a long time, the battery may discharge, and the engine may be unable to start. (The battery recharges automatically during driving.)

CAUTION

■Avoiding battery fires or explosions

Observe the following precautions to prevent accidentally igniting the flam- mable gas that may be emitted from the battery: ●Make sure the jumper cable is connected to the correct terminal and that it is not unintentionally in contact with any other than the intended terminal. ●Do not allow the + and - clamps of the jumper cables to come into contact

with each other.

●Do not smoke, use matches, cigarette lighters or allow open flame near

the battery.

■Battery precautions

The battery contains poisonous and corrosive acidic electrolyte, while related parts contain lead and lead compounds. Observe the following pre- cautions when handling the battery: ●When working with the battery, always wear safety glasses and take care not to allow any battery fluids (acid) to come into contact with skin, clothing or the vehicle body.

●Do not lean over the battery. ●In the event that battery fluid comes into contact with the skin or eyes, immediately wash the affected area with water and seek medical attention. Place a wet sponge or cloth over the affected area until medical attention can be received.

●Always wash your hands after handling the battery support, terminals, and

other battery-related parts.

●Do not allow children near the battery.

NOTICE

■When handling jumper cables

When connecting the jumper cables, ensure that they do not become entan- gled in the cooling fans or belt.

■To prevent damage to the engine cover

●When removing the cover, make sure that you pull the cover towards you

after lifting the front edge to remove the fixed pins.

●When installing the cover, do not force the cover or subject it to strong

shocks.

5-2. Steps to take in an emergency If your vehicle overheats

If your engine overheats: STEP 1

Stop the vehicle in a safe place and turn off the air condi- tioning system. Check to see if steam is coming out from under the hood. If you see steam:

STEP 2

Stop the engine. Carefully lift the hood after the steam subsides and then restart the engine.

If you do not see steam:

Leave the engine running and carefully lift the hood.

STEP 3

Check to see if the cooling fans are operating. If the fans are operating:

Wait until the temperature of the engine (shown on the instrument cluster) begins to fall and then stop the engine.

If the fans are not operating:

Stop the engine immediately and call your Toyota dealer. After the engine has cooled down sufficiently, check the engine coolant level and inspect the radiator core (radi- ator) for any leaks.

5-2. Steps to take in an emergency

CAUTION

■To prevent an accident or injury when inspecting under the hood of

your vehicle ●If steam is seen coming from under the hood, do not open the hood until the steam has subsided. The engine compartment may be very hot, caus- ing serious injuries such as burns.

●Keep hands and clothing away from the fans and drive belt while the

engine is running.

●Do not loosen the coolant reservoir cap while the engine and radiator are

hot. Serious injury, such as burns, may result from hot coolant and steam released under pressure.

NOTICE

■When adding engine coolant

Wait until the engine has cooled down before adding engine coolant. When adding coolant, do so slowly. Adding cool coolant to a hot engine too quickly can cause damage to the engine.

STEP 5

CAUTION

■When attempting to free a stuck vehicle

If you choose to push the vehicle back and forth to free it, make sure the sur- rounding area is clear to avoid striking other vehicles, objects or people. The vehicle may also lunge forward or lunge back suddenly as it becomes free. Use extreme caution.

■When shifting the shift lever

Be careful not to shift the shift lever with the accelerator pedal depressed. This may lead to unexpected rapid acceleration of the vehicle that may cause an accident resulting in death or serious injury.

5-2. Steps to take in an emergency If your vehicle has to be stopped in an emergency

Only in an emergency, such as if it becomes impossible to stop the vehicle in the normal way, stop the vehicle using the following pro- cedure: STEP 1

Steadily step on the brake pedal with both feet and firmly depress it. Do not pump the brake pedal repeatedly as this will increase the effort required to slow the vehicle. Shift the shift lever to N.

STEP 2

If the shift lever is shifted to N STEP 3

After slowing down, stop the vehicle in a safe place by the road. Stop the engine.

STEP 4

If the shift lever cannot be shifted to N STEP 3

Keep depressing the brake pedal with both feet to reduce vehicle speed as much as possible.

STEP 4

Vehicles without a smart key system: Stop the engine by turning the engine switch to the “ACC” position.

consecutive seconds or more.

Press and hold for 3 seconds or more

STEP 5

Stop the vehicle in a safe place by the road.

CAUTION

■If the engine has to be turned off while driving

●Power assist for the brakes and steering wheel will be lost, making the brake pedal harder to depress and the steering wheel heavier to turn. Decelerate as much as possible before turning off the engine.

●Vehicles without a smart key system: Never attempt to remove the key, as

doing so will lock the steering wheel.

SIENNA_U (OM45477U)

6-1. Specifications Fuel information

You must only use unleaded gasoline in your vehicle. Select octane rating 87 (Research Octane Number 91) or higher. Use of unleaded gasoline with an octane rating lower than 87 may result in engine knocking. Persistent knocking can lead to engine damage. At minimum, the gasoline you use should meet the specifications of ASTM D4814 in the U.S.A. and CGSB3.5-M93 in Canada.

■Fuel tank opening for unleaded gasoline

To help prevent incorrect fueling, your Toyota has a fuel tank opening that only accommodates the special nozzle on unleaded fuel pumps.

■Gasoline quality

In very few cases, driveability problems may be caused by the brand of gas- oline you are using. If driveability problems persist, try changing the brand of gasoline. If this does not correct the problem, consult your Toyota dealer.

■Gasoline quality standards

●Automotive manufacturers in the U.S.A., the Europe and Japan have developed a specification for fuel quality called World-Wide Fuel Charter (WWFC), which is expected to be applied worldwide.

●The WWFC consists of four categories that are based on required emis-

sion levels. In the U.S., category 4 has been adopted.

●The WWFC improves air quality by lowering emissions in vehicle fleets,

and improves customer satisfaction through better performance.

797

SIENNA_U (OM45477U)

6-1. Specifications

■Recommendation of the use of gasoline containing detergent additives ●Toyota recommends the use of gasoline that contains detergent additives

to avoid build-up of engine deposits.

●All gasoline sold in the U.S.A. contains detergent additives to clean and/

or keep clean intake systems.

■Recommendation of the use of cleaner burning gasoline

Cleaner burning gasoline, including reformulated gasoline that contains oxy- genates such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in many areas. Toyota recommends the use of cleaner burning gasoline and appropriately blended reformulated gasoline. These types of gasoline provide excellent vehicle performance, reduce vehicle emissions and improve air quality.

■Non-recommendation of the use of blended gasoline

DO NOT use gasoline containing more than 10% ethanol.

(15% ethanol)

(50% ethanol)

(85% ethanol)

●Use only gasoline containing a maxi-

mum of 10% ethanol. DO NOT use any flex-fuel or gasoline that could contain more than 10% etha- nol, including from any pump labeled E15, E30, E50, E85 (which are only some examples of fuel containing more than 10% ethanol).

●If you use gasohol in your vehicle, be sure that it has an octane rating no

lower than 87.

●Toyota does not recommend the use of gasoline containing methanol.

798

SIENNA_U (OM45477U)

6-1. Specifications

■Non-recommendation of the use of gasoline containing MMT

Some gasoline contains an octane enhancing additive called MMT (Methyl- cyclopentadienyl Manganese Tricarbonyl). Toyota does not recommend the use of gasoline that contains MMT. If fuel containing MMT is used, your emission control system may be adversely affected. The malfunction indicator lamp on the instrument panel may come on. If this happens, contact your Toyota dealer for service.

■If your engine knocks

●Consult your Toyota dealer. ●You may occasionally notice light knocking for a short time while acceler-

ating or driving uphill. This is normal and there is no need for concern.

799

SIENNA_U (OM45477U)

6-1. Specifications

NOTICE

■Notice on fuel quality

●Do not use improper fuels. If improper fuels are used, the engine will be

damaged.

●Do not use leaded gasoline.

Leaded gasoline can cause damage to your vehicle’s catalytic converters causing the emission control system to malfunction.

●Do not use gasohol other than that stated here.

Other gasohol may cause fuel system damage or vehicle performance problems.

●Using unleaded gasoline with an octane number or rating lower than the

level previously stated will cause persistent heavy knocking. At worst, this will lead to engine damage.

■Fuel-related poor driveability

If poor driveability is encountered after using a different type of fuel (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 paint.

Uniform Tire Quality Grading

This 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 shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A

805

SIENNA_U (OM45477U)

6-1. Specifications

■ 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 government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, performance may differ significantly from the norm due to variations in driving habits, service practices and differences in road characteristics 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 as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on braking (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 ability to dissipate heat when tested under controlled conditions on a speci- fied indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passen- ger car tires must meet under the Federal 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 properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either sepa- rately or in combination, can cause heat buildup and possible tire fail- ure.
