■Limitations of the Automatic High Beam

Do not rely on the Automatic High Beam. Always drive safely, taking care to observe your surroundings and turning high beam on or off manually if nec- essary.

■Camera sensor detection information

●High beam may not be automatically turned off in the following situations:

• When oncoming vehicles suddenly appear from a curve. • When the vehicle is cut in front of by another.

●High beam may be turned off if an oncoming vehicle that is using fog

lights without using the headlights is detected.

●Houselights, streetlights, red traffic signals, and illuminated billboards or

signs may cause the high beam to turn off.

●The following factors may affect the amount of time taken to turn high

beam on or off: • The brightness of headlights, fog lights, and tail lights of oncoming and

preceding vehicles

• Road conditions (wetness, ice, snow etc.) • The number of passengers and amount of baggage

●High beam may be turned on or off when unexpected by the driver.

2-3. Operating the lights and wipers

●In the situations below, the system may not be able to correctly detect the surrounding brightness levels, and may flash or expose nearby pedestri- ans to the high beam. Therefore, you should consider turning the high beam on or off manually rather than relying on the Automatic High Beam system. • In bad weather (rain, snow, fog, sandstorms etc.) • The windshield is obscured by fog, mist, ice, dirt etc. • The windshield is cracked or damaged. • The inside rear view mirror or camera sensor is deformed or dirty. • Surrounding brightness levels are equal to those of headlights, tail

lights or fog lights.

• Vehicles ahead have headlights that are either switched off, dirty, are

changing color, or are not aimed properly.

• When driving through an area of intermittently changing brightness and

• When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces (such as stone-paved roads, gravel tracks etc.)

Driving in vehicle-to-vehicle distance control mode

This mode employs a radar sensor to detect the presence of vehicles up to approximately 400 ft. (120 m) ahead, determines the current vehicle-to-vehicle following distance, and operates to maintain a suit- able following distance from the vehicle ahead.

Note that vehicle-to-vehicle distance will close in when traveling on long downhill slopes.

Example of constant speed cruising When there are no vehicles ahead The vehicle travels at the speed set by the driver. The desired vehicle-to- vehicle distance can also be set by operating the vehicle-to-vehicle dis- tance control. Example of deceleration cruising When the vehicle ahead is driving slower than the set speed When a vehicle is detected running ahead of you, the system automati- cally decelerates your vehicle. When a greater reduction in vehicle speed is necessary, the system applies the brakes. A warning tone warns you when the system cannot decelerate sufficiently to prevent your vehicle from closing in on the vehicle ahead.

307

SIENNA_OM_OM45483U_(U)

2-4. Using other driving systems

Example of follow-up cruising When following a vehicle driving slower than the set speed The system continues follow-up cruising while adjusting for changes in the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle dis- tance set by the driver. Example of acceleration When there are no longer any vehicles ahead driving slower than the set speed The system accelerates until the set speed is reached. The system then returns to constant speed cruising.

Approach warning

When your vehicle is too close to a vehicle ahead, and sufficient automatic deceleration via the cruise control is not possible, the dis- play will flash and the buzzer will sound to alert the driver. An exam- ple of this would be if another driver cuts in front of you while you are following a vehicle. Apply the brakes to ensure an appropriate vehi- cle-to-vehicle distance. ■ Warnings may not occur when

In the following instances, there is a possibility that the warnings will not occur: ● When the speed of the vehicle ahead matches or exceeds your

vehicle speed

● When the vehicle ahead is traveling at an extremely slow speed ● Immediately after the cruise control speed was set ● At the instant the accelerator is applied

CAUTION

■Before using dynamic radar cruise control

Do not overly rely on vehicle-to-vehicle distance control. Be aware of the set speed. If automatic deceleration/acceleration is not appropriate, adjust the vehicle speed, as well as the distance between your vehicle and vehicles ahead by applying the brakes, etc.

■Caution regarding the driving assist systems

Observe the following precautions. Failure to do so may cause an accident resulting in death or serious injury. ●Assisting the driver to measure following distance

The dynamic radar cruise control is only intended to help the driver in determining the following distance between the driver’s own vehicle and a designated vehicle travelling ahead. It is not a mechanism that allows careless or inattentive driving, and it is not a system that can assist the driver in low-visibility conditions. It is still necessary for driver to pay close attention to the vehicle’s surroundings.

●Assist the driver to judge proper following distance

The dynamic radar cruise control determines whether the following dis- tance between the driver’s own vehicle and a designated vehicle travelling ahead is appropriate or not. It is not capable of making any other type of judgement. Therefore, it is absolutely necessary for the driver to remain vigilant and to determine whether or not there is possibility of danger in any given situation.

●Assisting the driver to operate the vehicle

The dynamic radar cruise control has no capability to prevent or avoid a collision with a vehicle travelling ahead. Therefore, if there is ever any danger, the driver must take immediate and direct control of the vehicle and act appropriately in order to ensure the safety of all involved.

■To avoid inadvertent cruise control activation

Switch the cruise control off using the “ON-OFF” button when not in use.

■When the sensor may not be correctly detecting the vehicle ahead

Apply the brakes as necessary when any of the following types of vehicles are in front of you. As the sensor may not be able to correctly detect these types of vehicles, the approach warning (P. 308) will not be activated, and a fatal or serious accident may result. ●Vehicles that cut in suddenly ●Vehicles traveling at low speeds ●Vehicles that are not moving ●Vehicles with small rear ends (trailers with no load on board etc.) ●Motorcycles traveling in the same lane

■Conditions under which the vehicle-to-vehicle distance control may

not function correctly Apply the brakes as necessary in the following conditions as the radar sen- sor may not be able to correctly detect vehicles ahead, and a fatal or serious accident may result: ●When water or snow thrown up by the surrounding vehicles hinders the

functioning of the sensor

●When your vehicle is pointing upwards (caused by a heavy load in the lug-

gage compartment, etc.)

●When the road curves or when the lanes are narrow ●When steering wheel operation or your position in the lane is unstable ●When the vehicle ahead of you decelerates suddenly

2-4. Using other driving systems Driving assist systems

To help enhance driving safety and performance, the following sys- tems operate automatically in response to various driving situations. Be aware, however, that these systems are supplementary and should not be relied upon too heavily when operating the vehicle. ■ ABS (Anti-lock Brake System)

Helps to prevent wheel lock when the brakes are applied suddenly, or if the brakes are applied while driving on a slippery road surface

■ Brake assist

Generates an increased level of braking force after the brake pedal is depressed, when the system detects a panic stop situation

■ VSC (Vehicle Stability Control)

Helps the driver to control skidding when swerving suddenly or turning on slippery road surfaces

■ Enhanced VSC (Enhanced Vehicle Stability Control)

Provides cooperative control of the ABS, TRAC, VSC and EPS. Helps to maintain directional stability when swerving on slippery road surfaces by controlling steering performance.

■ TRAC (Traction Control)

Helps to maintain drive power and prevent the drive wheels from spin- ning when starting the vehicle or accelerating on slippery roads

■ Hill-start assist control (if equipped)

P. 337

■ EPS (Electric Power Steering)

Employs an electric motor to reduce the amount of effort needed to turn the steering wheel

■Sounds and vibrations caused by ABS, brake assist, Enhanced VSC

and TRAC ●A sound may be heard from the engine compartment when the engine is started or just after the vehicle begins to move. This sound does not indi- cate that a malfunction has occurred in any of these systems.

●Any of the following conditions may occur when the above systems are

operating. None of these indicates that a malfunction has occurred. • Vibrations may be felt through the vehicle body and steering. • A motor sound may be heard after the vehicle comes to a stop. • The brake pedal may pulsate slightly after ABS is activated. • The brake pedal may move down slightly after ABS is activated.

■EPS operation sound

When the steering wheel is operated, a motor sound (whirring sound) may be heard. This does not indicate a malfunction.

■Reactivation of the TRAC and VSC systems after turning off the engine Turning off the engine after turning off the TRAC and VSC systems will auto- matically reactivate them.

■Reactivation of the TRAC system linked to vehicle speed

When only the TRAC system is turned off, the TRAC system will turn on when vehicle speed increases. However, when both TRAC and VSC sys- tems are turned off, the systems will not turn on even when vehicle speed increases.

■Reduced effectiveness of the EPS system

The effectiveness of the EPS system is reduced to prevent the system from overheating when there is frequent steering input over an extended period of time. The steering wheel may feel heavy as a result. Should this occur, refrain from excessive steering input or stop the vehicle and turn the engine off. The EPS system should return to normal within 10 minutes.

CAUTION

■ABS does not operate effectively when

●The limits of tire gripping performance have been exceeded (such as

excessively worn tires on a snow covered road).

●The vehicle hydroplanes while driving at high speed on wet or slick roads. ■Stopping distance when ABS is operating may exceed that of normal

conditions The ABS is not designed to shorten the vehicle’s stopping distance. Always maintain a safe distance from the vehicle in front of you, especially in the fol- lowing situations. ●When driving on dirt, gravel or snow-covered roads ●When driving with tire chains ●When driving over bumps in the road ●When driving over roads with potholes or roads with uneven surfaces

■TRAC may not operate effectively when

Directional control and power may not be achievable while driving on slip- pery road surfaces, even if the TRAC system is operating. Do not drive the vehicle in conditions where stability and power may be lost.
