Checking battery condition— —Precautions

CAUTION

BATTERY PRECAUTIONS The battery produces flammable and explosive hydrogen gas. D Do not cause a spark from the bat-

tery with tools.

D Do not smoke or light a match near

the battery.

The electrolyte contains poisonous and corrosive sulfuric acid. D Avoid contact with eyes, skin or

clothes.

D Never ingest electrolyte. D Wear protective safety glasses when

working near the battery.

D Keep children away from the bat-

tery.

D If electrolyte gets on your skin, thoroughly wash the contact area. If you feel pain or burning, get medi- cal attention immediately.

D If electrolyte gets on your clothes, there is a possibility of its soaking through to your skin, so immediate- ly take off the exposed clothing and follow the procedure above, if nec- essary.

D If you accidentally swallow electro- lyte, drink a large quantity of water or milk. Follow with milk of magne- sia, beaten raw egg or vegetable oil. Then go immediately for emer- gency help.

EMERGENCY MEASURES D If electrolyte gets

If the headlights or other electrical components do not work, check the fuses. If any of the fuses are blown, they must be replaced. See “Fuse locations” on page 449 in Sec- tion 7−1 for locations of the fuses. Turn the ignition switch and inoperative component off. Pull the suspected fuse straight out and check it. Determine which fuse may be causing the problem. The lid of the fuse box shows the name of the circuit for each fuse. See page 492 in Section 8 of this manual for the functions controlled by each circuit. Type C and D—When any of the fuses are blown, contact your Toyota dealer.

2004 SIENNA from Aug. ’04 Prod. (OM45422U)

Type A fuses can be pulled out by the pull−out tool. The location of the pull−out tool is shown in the illustration. If you are not sure whether the fuse has blown, try replacing the suspected fuse with one that you know is good. If the fuse has blown, push a new fuse into the clip. Only install a fuse with the amperage rat- ing designated on the fuse box lid. If you do not have a spare fuse, in an emergency you can pull out the “HTR” (10
A), “AC INV” or “RAD NO.1” fuse, which may be dispensable for normal driving, and use it if its amperage rating is the same. If you cannot use one of the same amper- age, use one that is lower, but as close to the rating as possible. If the amperage is fuse might blow out again but this does not indicate anything wrong. Be sure to get the correct fuse as soon as possible and return the substitute to its original clip. It is a good idea to purchase a set of spare fuses and keep them in your ve- hicle for emergencies.

If fuse immediately blows out, there is a problem with the electrical sys- tem. Have your Toyota dealer correct it as soon as possible.

CAUTION

Never use a fuse with a higher am- perage rating, or any other object, in place of a fuse. This may cause ex- tensive damage and possibly a fire.

Adding washer fluid If any washer does not work or the low windshield washer fluid level warning light comes on, the washer tank may be empty. Add washer fluid. You may use plain water as washer fluid. However, in cold areas where tempera- tures range below the freezing point, use washer fluid containing antifreeze. 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.

Introduction & Operation

SIENNA (QRG_U)

This quick reference guide provides you with information on Dynamic Laser Cruise Control Vehicle- to- Vehicle Distance Control Mode. Prior to use of this system, you should be thoroughly familiar with this system, referring to “Dynamic Laser Cruise Control” in Section 1- 6, Owner’s Manual in conjunction with this quick reference guide. (cid:3) Dynamic Laser Cruise Control Operation The laser radar sensor in this system primarily detects the reflectors of the vehicle ahead of you to determine the presence of the vehicle and the vehicle- to- vehicle distance. The detection range of the sensor is about 120 m (400 ft.) ahead. (cid:2) If no vehicle is detected ahead of you:

(cid:1) Your cruising speed is maintained at the preset speed from about 45 km/h (28 mph) to about 135 km/h (85 mph).

(cid:2) If a vehicle is detected ahead of you:

(cid:1) Your cruising speed changes in proportion to the speed of the vehicle ahead to maintain an appropriate distance from your vehicle

to the vehicle ahead.

(cid:1) If the vehicle ahead is out of the detection range, your cruising speed will be gradually increased up to the preset speed, and your

vehicle resumes fixed- speed cruising.

(cid:1) If the vehicle ahead decelerates abruptly or other vehicles cut in ahead of you, your vehicle may be too close to the vehicle ahead

of you. If this occurs, the display flashes and beeps. (Approach warning)

The dynamic laser cruise control should be used on roads in which sufficient vehicle- to- vehicle distance will be ensured (such as on freeways).

The wipers are not operating at all or operating intermittently (including the same wiper operation in the “AUTO” position).

Even if these requirements are met, the system may not operate properly under certain conditions such as bad weather. See “Owner’s Manual” for details.

The selector lever is in the “D” position.

Introduction & Operation

SIENNA (QRG_U)

(cid:3) Cautions (cid:2) Do not rely too much on dynamic laser cruise control. Vehicle- to- vehicle distance control has its limitations.

Always remain aware of the distance from the vehicle ahead and other vehicles. If necessary, depress the brake pedal to ensure sufficient distance.

(cid:2) Dynamic laser cruise control is not a collision- avoidance system.

If necessary, depress the brake pedal to ensure sufficient distance.

(cid:2) Dynamic laser cruise control should not be used in the following conditions:

(cid:1) In bad weather (such as rain, fog, snow, sandstorms) (cid:1) In direct sunlight from the front (cid:1) Raindrops or snowflakes get in the laser radar sensor glass (cid:1) On the roads in heavy traffic or at sharp bends (cid:1) On slippery road surfaces (icy or snow- covered road surfaces) (cid:1) On steep downhill slopes (cid:1) Continual acceleration or deceleration (such as on busy traffic) (cid:1) On roads with steep and short inclines and declines In any conditions of the above, an appropriate vehicle- to- vehicle distance control may not be attained.

(cid:2) This system is not provided to justify careless driving.

Always remain aware of the distance from the vehicle ahead and other vehicles.

(cid:2) The dynamic laser cruise control should not be used when exiting from,

or when entering or merging onto a freeway. When you are following a slower moving vehicle and exiting, the sensor does not detect the vehicle and will accelerate to preset speed.

y16079q

SIENNA (QRG_U)

(cid:3) Cautions (cid:2) If other vehicles are driving outside of the laser radar detection range, a delay in the detection of the vehicle cutting in

at short range or detection failure of the motorcycle running on the side of the same lane will occur. In this case, the dynamic laser cruise control system will not function properly.

(cid:2) The distance between your vehicle and the vehicle ahead cannot be accurately detected in the following cases:

(cid:1) The vehicle ahead has higher ground clearance, which means that the placement of the reflectors is in a higher position. (cid:1) The rear section of the vehicle ahead is extremely dirty. (cid:1) The vehicle ahead or other vehicles around you are flinging up water or snow. (cid:1) Excessive exhaust gas (black smoke) is coming from the vehicle ahead or other vehicles around you, obscuring your front

view.

(cid:1) Protective film is attached to the reflectors on the vehicle ahead, or reflectors are not installed on the vehicle ahead or are

damaged.

(cid:1) Heavy luggage is loaded on top of your rear seats.

(cid:2) The laser radar sensor automatically detects dirt if dirt is sticking to the sensor glass of your vehicle.

However, in some cases dirt may not be detected. At this time warning display does not operate and an appropriate vehicle- to- vehicle distance cannot be maintained. Continue driving with due care to the vehicle ahead.

(cid:2) Dynamic laser cruise control does not operate when the vehicle is at a stop or is driving very slowly.

(cid:1) Pay special attention to the very slow vehicle at the end of the line in heavy traffic or at the toll gate.

(cid:2) Turn off the main switch when dynamic laser cruise control is not in use. (cid:2) The approach warning may not turn on even if the vehicle drives closer to the vehicle ahead in the following conditions:

(cid:1) Your vehicle and the vehicle ahead are cruising at almost the same speed. (cid:1) The vehicle ahead is cruising at a faster speed than yours. (The distance between the vehicles will become longer.) (cid:1) The accelerator pedal is depressed, immediately after the release of the accelerator pedal or immediately after the speed

setting.

(cid:2) Depending on the road configuration (curved roads) or your vehicle condition (steering wheel maneuvering, position in

the lane), vehicles in other lanes or surrounding objects will be detected.

Use caution for the vehicle at the end of the line in heavy traffic or at the tollgate, the vehicle at a stop and the very slow vehicle. If your vehicle approaches the vehicle ahead because of insufficient braking when the vehicle ahead decelerates abruptly or when another vehicle cuts in ahead of you, the display flashes and beeps. Depress the brake pedal to slow down, ensuring sufficient vehicle- to- vehicle distance.
