■Maintenance


●If you tow a trailer, your vehicle will require more frequent maintenance due to the additional load. (See “Scheduled Maintenance Guide” or “Owner’s Manual Supplement”.)


●Retighten the fixing bolts of the towing ball and bracket after approximately


600 miles (1000 km) of trailer towing.


■If trailer sway occurs


One or more factors (crosswinds, passing vehicles, rough roads, etc.) can adversely affect handling of your vehicle and trailer, causing instability. ●If trailer swaying occurs:


• Firmly grip the steering wheel. Steer straight ahead.


Do not try to control trailer swaying by turning the steering wheel.


• Begin releasing the accelerator pedal immediately but very gradually to


reduce speed. Do not increase speed. Do not apply vehicle brakes.


If you make no extreme correction with the steering or brakes, your vehicle and trailer should stabilize. ●After the trailer swaying has stopped:


• Stop in a safe place. Get all occupants out of the vehicle. • Check the tires of the vehicle and the trailer. • Check the load in the trailer.


Make sure the load has not shifted. Make sure the tongue weight is appropriate, if possible.


• Check the load in the vehicle.


Make sure the vehicle is not overloaded after occupants get in.


If you cannot find any problems, the speed at which trailer swaying occurred is beyond the limit of your particular vehicle-trailer combination. Drive at a lower speed to prevent instability. Remember that swaying of the towing vehicle-trailer increases as speed increases.

WARNING


■Trailer towing precautions


To tow a trailer safely, use extreme care and drive the vehicle in accordance with the trailer’s characteristics and operating conditions. Failure to do so could cause an accident resulting in death or serious injury. Vehicle stability and braking performance are affected by trailer stability, brake setting and performance, and the hitch. Your vehicle will handle differently when towing a trailer.


■To avoid accident or injury


●Do not exceed the TWR, unbraked TWR, GCWR, GVWR or GAWR. ●If the gross trailer weight is over 2000 lb. (907 kg), a sway control device


with sufficient capacity is required.


●Adjust the tongue weight within the appropriate range. Place heavier loads


as close to the trailer axle as possible.


●Do not exceed 65 mph (104 km/h), the posted towing speed limit or the speed limit for your trailer as set forth in your trailer owner’s manual, whichever is lowest. Slow down sufficiently before making a turn, in cross- winds, on wet or slippery surface, etc. to help avoid an accident. If you experience a vehicle-trailer instability from reducing a certain speed, slow down and make sure you keep your vehicle speed under the speed of which you experience the instability.


●Do not make jerky, abrupt or sharp turns. ●Do not apply the brakes suddenly as you may skid, resulting in jackknifing and loss of vehicle control. This is especially true on wet or slippery sur- faces.


●Do not exceed the trailer hitch assembly weight, gross vehicle weight,


gross axle weight and trailer tongue weight capacities.

WARNING


■To avoid accident or injury


●Do not use cruise control when towing. ●Slow down and downshift before descending steep or long downhill grades. Do not make sudden downshifts while descending steep or long downhill grades.


●Vehicle-trailer instability is more likely on steep long downhills. Before descending steep or long downhill grades, slow down and downshift. Do not make sudden downshifts when descending steep or long downhill grades. Avoid holding the brake pedal down too long or applying the brakes too frequently. This could cause the brakes to overheat and result in reduced braking efficiency.


●Vehicles with compact spare tire: Do not tow a trailer when the compact


spare tire is installed on your vehicle.


■Hitch


Trailer hitch assemblies have different weight capacities established by the hitch manufacturer. Even though the vehicle may be physically capable of towing a higher weight, the operator must determine the maximum weight rating of the particular hitch assembly and never exceed the maximum weight rating specified for the trailer-hitch. Exceeding the maximum weight rating set by the trailer-hitch manufacturer can cause an accident resulting in death or serious personal injuries.


■When towing a trailer


Toyota recommends trailers with brakes that conform to any applicable fed- eral and state/provincial regulations. ●If the gross trailer weight exceeds unbraked TWR, trailer brakes are required. Toyota recommends trailers with brakes that conform to all appli- cable federal and state/provincial regulations.


●Never tap into your vehicle’s hydraulic system, as this will lower the vehi-


cle’s braking effectiveness.


●Never tow a trailer without using a safety chain securely attached to both the trailer and the vehicle. If damage occurs to the coupling unit or hitch ball, there is danger of the trailer wandering into another lane.


NOTICE


■When installing a trailer hitch


Use only the position recommended by your Toyota dealer. Do not install the trailer hitch on the bumper; this may cause body damage.


■Do not directly splice trailer lights


Do not directly splice trailer lights. Directly splicing trailer lights may damage your vehicle’s electrical system and cause a malfunction.

■ Shift ranges and their functions


● Automatically selecting gears between 1 and 6 according to vehi- cle speed and driving conditions. But, the gear is limited accord- ing to selected shift range.


● You can choose from 6 levels of engine braking force. ● A lower shift range will provide greater engine braking force than


a higher shift range, and the engine speed will also increase.


■S mode


●When the shift range is 5 or lower, holding the shift lever toward “+” sets the


shift range to 6.


●To prevent excessive engine speed, a function was adopted that automati- cally selects a higher shift range before the engine speed becomes too high. ●To protect the automatic transaxle, a function is adopted that automatically


selects a higher shift range when the fluid temperature is high.


■Downshift restriction warning buzzer (S mode)


To help ensure safety and driving performance, downshifting operation may sometimes be restricted. In some circumstances, downshifting may not be possible even when the shift lever is operated. (A buzzer will sound twice.)


■When driving with the cruise control or dynamic radar cruise control


activated (if equipped) Even when performing the following actions with the intent of enabling engine braking, engine braking will not activate while driving in S mode and down- shifting to 5 or 4 because cruise control or dynamic radar cruise control will not be canceled. (P. 257, 261)

● Confirm the type of fuel.


■Fuel type


Unleaded gasoline (Octane rating 87 [Research Octane Number 91] or higher)


WARNING


■When refueling the vehicle


Observe the following precautions while refueling the vehicle. Failure to do so may result in death or serious injury. ●After exiting the vehicle and before opening the fuel door, touch an unpainted metal surface to discharge any static electricity. It is important to discharge static electricity before refueling because sparks resulting from static electricity can cause fuel vapors to ignite while refueling.


●Always hold the grips on the fuel tank cap and turn it slowly to remove it. A whooshing sound may be heard when the fuel tank cap is loosened. Wait until the sound cannot be heard before fully removing the cap. In hot weather, pressurized fuel may spray out of the filler neck and cause injury.


●Do not allow anyone that has not discharged static electricity from their


body to come close to an open fuel tank.


●Do not inhale vaporized fuel.


Fuel contains substances that are harmful if inhaled.


●Do not smoke while refueling the vehicle.


Doing so may cause the fuel to ignite and cause a fire.


●Do not return to the vehicle or touch any person or object that is statically


charged. This may cause static electricity to build up, resulting in a possible ignition hazard.

Canceling and resuming the speed control


Pulling the lever toward you cancels the cruise control. The speed setting is also canceled when the brakes are applied. Pushing the lever up resumes the cruise control and returns vehicle speed to the set speed.


Resuming is available when the vehicle speed is more than approximately 25 mph (40 km/h).


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.


SIENNA_OM_01999-08001_(U)


266


4-5. Using the driving support systems


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 automatically 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 clos- ing in on the vehicle ahead. 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 auto- matic deceleration via the cruise control is not possible, the display will flash and the buzzer will sound to alert the driver. An example of this would be if another driver cuts in front of you while you are follow- ing a vehicle. Apply the brakes to ensure an appropriate vehicle-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
