(b) Normal driving 1. Start the engine as instructed in “How to start the engine” on page 452 in Section 3. The transmission must be in “P” or “N”.

2. With your foot holding down the brake

pedal, shift the selector lever to “D”.

When the lever is in the “D” position, the automatic transmission system will select the most suitable gear for running condi- tions such as normal cruising, hill climb- ing, hard towing, etc. Always use the “D” position for better fuel economy and quieter driving. If the engine coolant temperature is low, the transmis- sion will not shift into the overdrive gear even in the “D” position.

(c) Using engine braking To use engine braking, you can downshift the transmission as follows: D Shift into the “4” position. The trans- fourth gear

mission will downshift and engine braking will be enabled.

The tire pressure warning light may turn on due to natural causes such as natural air leaks or tire inflation pressure changes caused by temperature. In this case, ad- justing the tire inflation pressure will turn off the light after several minutes. Pushing the tire pressure warning reset switch should not turn off the tire pressure warning light. Adjusting the tire inflation pressure will turn off the light. The compact spare tire is not equipped with the tire pressure warning valve and transmitter. If a tire goes flat, the warning light will not turn off even though the flat tire is replaced with the spare tire. Re- place the spare tire with the repaired tire and adjust the proper tire inflation pressur- e. The tire pressure warning light will turn off after several minutes.

CAUTION

Each tire, including the spare (if pro- vided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label (tire and load information label). (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label (tire and load information label), you should determine the proper tire infla- tion pressure for those tires.)

As an added safety feature, your ve- hicle has been equipped with a tire pressure monitoring system (TPMS– tire pressure warning system) that il- luminates a low tire pressure telltale (tire pressure warning light) when one or more of your tires is significantly under−inflated. Accordingly, when the low tire pressure telltale (tire pres- sure warning illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a sig- nificantly under−inflated tire causes the tire to overheat and can lead to tire failure. Under−inflation also re- duces fuel efficiency and tire tread life, and may affect the vehicle’s han- dling and stopping ability.

Your vehicle has also been equipped with a TPMS (tire pressure warning system) malfunction indicator to indi- cate when the system is not operat- ing properly. The TPMS (tire pressure warning system) malfunction indicator is combined with the low tire pres- sure (tire pressure warning telltale light). When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subse- quent vehicle start−ups as long as the malfunction exists. When the mal- function indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended.

from

TPMS (tire pressure warning system) malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS (tire pressure warning sys- tem) functioning properly. Al- ways check the TPMS (tire pressure warning system) malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS (tire pressure warning system) to continue to func- tion properly.

TIRE PRESSURE WARNING RESET SWITCH When initializing the system, the present tire inflation pressure is stored as stan- dard. The tire pressure warning system determines decreased air pressure by comparing the present and the standard tire inflation pressures. When you change the set tire inflation pressure, it is neces- sary to initialize the tire pressure warning system. When changing the tire size.

To initialize the system, perform the fol- lowing: 1. Park the vehicle in a safe place and

turn the engine switch off.

2. Adjust the pressure of all the installed tires to the specified cold tire inflation pressure level. (See “Tires” on page 553 in Section 8.)

3. Turn the engine switch is in “ON” posi-

tion.

4. Push and hold the tire pressure warn- ing reset switch until the tire pressure warning light blinks slowly three times. 5. Wait for several minutes with the en- gine switch “ON”, and then turn the engine switch to the “ACC” or “LOCK” position.

If you push the tire pressure warning re- set switch while the vehicle is moving, initialization is not performed. If you push the tire pressure warning re- set switch accidentally and initialization is performed, adjust the tire inflation pres- sure to the specified level and initialize the system again.

The buzzer will remind you to release the parking brake when the vehicle speed rises above 5 km/h (3 mph) with the park- ing brake is applied.

CAUTION

Before driving, be sure the parking brake is fully released and the park- ing brake reminder light is off.

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.

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.

D Be careful about vehicle speed as it may increase when driving down- hill with the cruise control on.

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 engine switch 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.

CAUTION

To avoid accidentally engaging the cruise control, turn the system off when it is not in use. Make sure the “CRUISE” indicator light is off.

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.

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: D Pulling the lever in the “CANCEL” di-

rection and releasing it

D Depressing the brake pedal Under certain circumstances, control is temporarily cancelled: D When vehicle speed

—Vehicle−to−vehicle distance control mode The system’s laser radar sensor detects the reflectors of vehicles and measures the vehicle−to−vehicle distance. The detection range of the sensor 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.

DYNAMIC LASER CRUISE CONTROL OPERATIONS The dynamic laser cruise control func- tion operates automatically and depend- ing on whether a vehicle is detected ahead may change the speed of your vehicle as follows. If no vehicle is running ahead of you— 1. Cruising at a fixed speed: If there is your no cruising speed the preset speed from about 45 km/h (28
mph) to about 135 km/h (85 mph). The preset speed the display. For the vehicle speed setting, see “SETTING THE CRUISING SPEED” on page 231.

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 233.

4. Acceleration cruising function: If the vehicle ahead changes lanes, your ve- hicle cruising speed will be gradually increased up to the preset speed, and your fixed−speed cruising.

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

08 SIENNA_U (L/O 0801)

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.

Dynamic laser cruise control should not be used in circumstances which are inap- propriate for any cruise control, such as entering free way on−ramps or off−ramps.

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.

D When a slower vehicle in front of you leaves the lane, the dynamic laser cruise control will no longer detect a vehicle ahead and will at- tempt to accelerate the vehicle to the faster preset speed.
