This light reminds you to buckle up the front passenger’s seat belt. Once the ignition key is turned to “ON”, the reminder light flashes if a passenger sits in the front passenger seat and does not fastened. However, if a front passen- ger uses an additional seat cushion, the light may not flash even when the seat belt is not buckled up. If luggage or other load is placed on the front passenger seat, depending on its weight and how it is placed on the seat, built−in sensors in the seat cushion may detect the pressure, causing the reminder light to come on.

(d) Discharge Warning Light This light warns that the battery is being discharged. If it comes on while you are driving, there is a problem somewhere in the charging system. The engine ignition will continue to oper- the battery ate, however, until is dis- charged. Turn off the air conditioning, blower, radio, etc., and drive directly to the nearest Toyota dealer or repair shop.

NOTICE

Do not continue driving if the engine drive belt is broken or loose.

(e) Malfunction Indicator Lamp This lamp comes on when the ignition key is turned to the “ON” position and goes off after the engine starts. This means that the warning light system is operating properly. If the lamp remains on, or the lamp comes on while driving, first check the followings. D Empty fuel tank

If the fuel tank is empty, refuel immedi- ately.

D Loose fuel tank cap

If the fuel tank cap is loose, securely tighten it.

These cases are temporary malfunctions. The malfunction indicator lamp will go off after taking several driving trips. If the lamp does not go off even after several trips, contact your Toyota dealer as soon as possible. If the fuel tank is not empty or the fuel tank cap is not loose... D There is a problem somewhere in the engine, emission control system, elec- tronic throttle control system, automatic transmission electrical system or warn- ing light system itself.

Contact your Toyota dealer as soon as possible to service the vehicle. If engine speed does not increase with the accelerator pedal depressed down, there may be a problem somewhere in your electronic throttle control system. At this time, vibration may occur. Howev- er, if you depress the accelerator pedal more firmly and slowly, you can drive your vehicle at low speeds. Have your vehicle checked by your Toyota dealer as soon as possible.

Even if the abnormality of the electronic throttle control system is corrected during low speed driving, the system may not be recovered until the engine is stopped and the to “ACC” or ignition key “LOCK” position.

Tire pressure warning system The tire pressure warning system is de- signed to provide warning when tire pressure of any one of the tires is criti- cally low while the vehicle is moving. The light comes on to inform you that such low tire pressure may hamper driving. This system is not designed to operate when the vehicle is stopped. Therefore, check the tire pressure regularly. The rec- ommended cold tire size and the vehicle capacity weight are on the tire pressure label. (For instructions, see “Checking tire inflation pressure” on page 463 in Section 7−2.) Installed tires should be of the specified size. They should be of the same size and construction. If tires other than the specified size are used, or if tires of dif- ferent sizes or constructions are mixed, the tire pressure warning system will not function properly.

Note: The tire pressure warning sys- tem on your vehicle will warn you when one of your tires is significantly under−inflated and when some com- binations of your tires are significant- ly under−inflated. However, there are other combinations of significantly under−inflated for which your tire pressure warning system may not warm you. These other combinations are relatively common, accounting for approximately half the in which vehicles have significantly un- der−inflated tires. For example, your system may not warm you when both tires on the same side or on the same axle of your vehicle are signifi- cantly under−inflated. It is particularly important, therefore, for you to check the tire pressure in all of your tires regularly and maintain proper pres- sure.

If the low tire pressure warning light does not blink when you push and hold the reset switch, have the low pressure warn- ing system checked at your Toyota dealer. When the warning light blinks twice every second while driving, you may be unable to reset the system. In this case, set the system again according to the above pro- cedure.

To initialize the system, perform the fol- lowing: 1. Park the vehicle at a safe place and apply the parking brake. Stop the en- gine.

2. Adjust the pressure of all the installed tires to the specified level. (See “Tires” on page 491 in Section 8.)

3. Turn the ignition key to “ON”. 4. Push and hold the reset switch until light

5. Initialization is completed after driving at the speeds of 30 km/h (19 mph) or over for about 8 hours total, when the tire pressure warning system detects the normal tire pressure.

When initializing the system, make sure the low tire pressure warning light blinks three times. If the warning light does not blink three times, initializing will be failed and the tire pressure warning system will not function properly. Do not push the reset switch without ad- justing the tire pressure to the specified level. Otherwise, tire pressure warning light may not come on even if the tire pressure is low, or it may come on when the tire pressure is actually normal. If you push the reset switch while the vehicle is moving, initialization is not per- formed.

Cruise control The cruise control allows you to cruise the vehicle at a desired speed over 40
km/h (25 mph) even with your foot off the accelerator pedal. Your cruising speed can be maintained up or down grades within the limits of engine performance, although a slight speed change may occur when driving up or down the grades. On steeper hills, a greater speed change will occur so it is better to drive without the cruise control.

CAUTION

D To help maintain maximum control of your vehicle, do not use the cruise control when driving in heavy or varying traffic, or on slip- pery (rainy, icy or snow−covered) or winding roads.

If

D Avoid vehicle speed increases when driving downhill. the vehicle speed is too fast in relation to the cruise control set speed, cancel the cruise control then downshift the transmission to use engine braking to slow down.

04 SIENNA_U (L/O 0408)

CAUTION

To avoid accidental cruise control en- gagement, keep the “ON−OFF” button off when not using the cruise control.

TURNING THE SYSTEM ON To operate the cruise control, press the “ON−OFF” button. This turns the system on. The indicator light in the instrument panel shows that you can now set the vehicle at a desired cruising speed. Anoth- er press will turn the system completely off. When the ignition is turned off, the system is also automatically turned off. To use cruise control again, press the “ON−OFF” button again to turn it on.

SETTING AT A DESIRED SPEED The transmission must be in “D” before you set the cruise control speed. Bring your vehicle to the desired speed, push the lever down in the “− SET” direc- tion and release it. This sets the vehicle at that speed. If the speed is not satisfac- tory, tap the lever up for a faster speed, or tap it down for a slower speed. Each tap changes the set speed by 1.6 km/h (1.0 mph). You can now take your foot off the accelerator pedal.

If you need acceleration—for example, when passing—depress the accelerator pedal enough for the vehicle to exceed the set speed. When you release it, the vehicle will return to the speed set prior to the acceleration. CANCELLING THE PRESET SPEED You can cancel the preset speed by: a. Pulling the lever in the “CANCEL” di-

rection and releasing it. b. Depressing the brake pedal.

If the vehicle speed falls below about 40
km/h (25 mph), the preset speed will auto- matically cancel out. If the vehicle speed drops 16 km/h (10
mph) below the preset speed, the preset speed will also automatically cancel out. If the preset speed automatically cancels out other than for the above cases, have your vehicle checked by your Toyota deal- er at the earliest opportunity.

RESETTING TO A FASTER SPEED Push the lever up in the “+ RES” direction and hold it. Release the lever when the desired speed is attained. While the lever is held up, the vehicle will gradually gain speed. However, a faster way to reset is to ac- celerate the vehicle and then push the lever down in the “− SET” direction. RESETTING TO A SLOWER SPEED Push the lever down in the “− SET” direc- tion and hold it. Release the lever when the desired speed is attained. While the lever is held down, the vehicle speed will gradually decrease. However, a faster way to reset is to de- press the brake pedal and then push the lever down in the “− SET” direction. Even if you downshift from “D” to “4”, with the cruise control on, engine braking will not be enabled because the cruise control is not cancelled. To decrease the vehicle speed, reset to a slower speed with the cruise control lever or depress the brake pedal. If you use the brake pedal, cruise control is cancelled.

RESUMING THE PRESET SPEED If the preset speed is cancelled by pulling the control the brake pedal, pushing the lever up in the “+ RES” direction will restore the speed set prior to cancellation. However, once the vehicle speed falls be- low about 40 km/h (25 mph), the preset speed will not be resumed. CRUISE CONTROL FAILURE WARNING If the instrument cluster flashes when using the cruise control, press the “ON−OFF” button to turn the system off and then press it again to turn it on.

—Vehicle−to−vehicle distance control mode The laser radar sensor in this system primarily detects the reflectors of the vehicle ahead of you to determine the presence of the vehicle ahead as well as measuring the vehicle−to−vehicle dis- tance. The detection range of the sen- sor is about 120 m (400 ft.) ahead.

CAUTION

Dynamic laser cruise control is not a collision−avoidance system and will not prevent accidents. Dynamic laser cruise control is a vehicle speed con- trol device that is intended for use only on freeways or roads where the traffic is light or moderate. To avoid serious injury, you must use caution and be attentive to road and traffic conditions while using dynamic laser cruise control.

km/h (85 mph). The display shows the preset speed, the detected vehicle ahead and selected vehicle−to−vehicle distance. If your vehicle gets closer to the vehicle ahead because of insuffi- cient automatic deceleration, then the alarm warns you to also manually ap- ply brakes.

3. Follow−up cruising function: After de- celeration, your vehicle cruising speed changes in proportion to the speed of the vehicle ahead to maintain an ap- propriate distance from your vehicle to the vehicle ahead. The vehicle−to−ve- hicle distance can be changed. For de- tails, see “CHANGING VEHICLE−TO− VEHICLE DISTANCE” on page 203.

Do not rely excessively on dynamic laser cruise control. Observe the fol- lowing precautions in order to avoid serious injury or death: D Under certain conditions where the vehicle in front slows drastically, or is stopped, the dynamic laser cruise control will neither warn you nor decelerate. You must depress the brake pedal to slow down, ensuring collision avoidance or that suffi- cient vehicle−to−vehicle distance is maintained.

D Do not use dynamic

laser cruise control in the following conditions: In bad weather (such as rain, fog, snow, sandstorms or direct sun- light, or when raindrops or snow- flakes get on the laser radar sensor glass), the vehicle−to−vehicle dis- tance will not be measured accura- tely. When using the windshield wipers at high or low speeds the dynamic laser radar cruise control turns off.

roads with heavy

On traffic or sharp bends, an appropriate speed cannot be maintained and an acci- dent may occur. On slippery road surfaces (icy or snow−covered road surfaces), the tires will race and you will be un- able to control the vehicle. When there is no vehicle detected ahead on steep downhill slopes, the preset speed will be easily exceed- ed because of inefficient engine braking. this case, automatic braking will not work.) If there is a vehicle detected ahead, the delay in deceleration timing could cause se- rious injury or death. When the alarm sounds frequently (because acceleration or decelera- tion was repeated or sufficient ve- hicle−to−vehicle distance was not maintained), an appropriate vehicle speed cannot be attained and an accident may occur.

(In

04 SIENNA_U (L/O 0408)

On roads with steep and short in- clines and declines, failure to de- tect the vehicle ahead will shorten the distance between your vehicle and the vehicle ahead and an acci- dent may occur.

D Deceleration cruising function and approach warning do not operate when the vehicle ahead is at a stop or driving very slowly.

D If the vehicle ahead of you deceler- ates abruptly or if another vehicle cuts in ahead of you, your vehicle may collide with the vehicle ahead unless you manually depress the brake pedal to slow down your ve- hicle.

D Depending on the road configura- tion (curved, left and right continu- ous curved, the start or end of a curve, or narrow driving lanes due to road construction) or your ve- hicle condition (steering wheel ma- neuvering, position in the lane, or unstable driving because of an acci- dent or breakdown), vehicles in oth- er lanes or surrounding objects may be detected, resulting in a con- trol failure or the approach warning activation. This may also result in a very close distance between vehi- cles due to a failure to detect the vehicle ahead.

CAUTION

D Do not use dynamic

laser cruise control when exiting from or when entering or merging onto a freeway. When you are following a slower moving vehicle and exiting, the sen- sor does not detect the vehicle and will accelerate to the preset speed.

D If other vehicles are driving outside of the laser radar detection range, a delay in the detection of the ve- hicle cutting in at short range or failure to detect a motorcycle run- ning on the side of the same lane will occur. In this case, the dynamic laser cruise control system will not function properly.
