reminder

The light and buzzer act as a reminder to buckle up the driver’s seat belt. Once the ignition key is turned to “ON”, the flashes and buzzer sounds if the driver’s seat belt is not fas- tened. Unless the driver fastens the belt, the light continues flashing and the buzzer stops after about 4 to 8 seconds. (c) Front Passenger’s Seat Belt Re-

light

minder Light

The light acts as a reminder to have the front passenger buckle up the 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 flash.

(d) Charging System Warning Light This warning the light comes on when ignition switch is turned to the “ON” posi- tion, and goes off when the engine is started. When there are problems in the charging system while the engine is running, the warning light comes on.

NOTICE

When the charging system warning light comes on while the engine is running, malfunctions such as the en- gine drive belt being broken may have occurred. If the warning light comes on, immediately stop the vehicle in a safe place and contact your Toyota dealer.

(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. (cid:1) Empty fuel tank

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

(cid:1) 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... (cid:1) 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 when the accelerator pedal is depressed, there may be a problem somewhere in the elec- tronic 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 ignition key to “ACC” or “LOCK” position.

tires

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.

Cruise control The cruise control is designed to main- tain a set cruising speed without requir- ing the driver to operate the accelera- tor. Cruising speed can be set to any speed above 40 km/h (25 mph). Within the limits of the engine’s capabili- ties, cruising speed can be maintained up or down grades. However, changes in ve- hicle speed may occur on steeper grades.

TURNING THE SYSTEM ON AND OFF To turn the cruise control on, press the “ON- OFF” button. The “CRUISE” indicator light on the instrument panel will come on to indicate that the cruise control is opera- tional. Pressing “ON- OFF” button again turns the system off. When the system is turned off, cruising speed must be reset when the cruise con- trol is turned on again. 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.

214

SETTING THE CRUISING SPEED The transmission must be in “D” or “4” before you set the cruising 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.

2006 SIENNA from March ‘06 Prod. (OM45443U)

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 CRUISE CONTROL The cruise control may be temporarily cancelled by the driver or by the system itself under certain circumstances. Tempo- rary cancellation allows the set cruising speed to remain in memory. The cruise control can be temporarily can- celled by doing the following: (cid:1) Pulling the lever in the “CANCEL” di-
