■Tire information
●Increase the tire inflation pressure to  
20.0 kPa (0.2 kgf/cm2 or bar, 3 psi)  greater than the recommended value when towing. ( P.624)
●Increase the air pressure of the trailer  
tires in accordance with the total  
trailer weight and according to the val- ues recommended by the manufac-turer of your trailer.
■Safety checks before towing
●Check that the maximum load limit for the towing hitch/bracket and hitch ball  
is not exceeded. Bear in mind that the  coupling weight of the trailer will add to the load exerted on the vehicle.  
Also make sure that the total load  exerted on the vehicle is within the range of the weight limits. ( P.309)
●Ensure that the trailer load is secure.
●Supplementary outside rear view mir- rors should be added to the vehicle if the traffic behind cannot be clearly  
seen with standard mirrors. Adjust the  extending arms of these mirrors on both sides of the vehicle so that they  
always provide maximum visibility of  the road behind.
Trailer towing
Your vehicle is designed pri- 
marily as a passenger carry- 
ing vehicle. Towing a trailer  
will have an adverse effect on  
handling, performance, brak- 
ing, durability, and fuel con- 
sumption. Your safety and  
satisfaction depend on the  
proper use of correct equip- 
ment and cautious driving hab- 
its. For your safety and the  
safety of others, do not over- 
load the vehicle or trailer.
To tow a trailer safely, use  
extreme care and drive the  
vehicle in accordance with the  
trailer’s characteristics and  
operating conditions.
Toyota warranties do not apply  
to damage or malfunction  
caused by towing a trailer for  
commercial purposes.
Ask your local authorized  
Toyota retailer or Toyota  
authorized repairer, or any reli- 
able repairer for further details  
before towing, as there are  
additional legal requirements  
in some countries.
WARNING
Follow all the instructions described in  
this section. Failure to do so could cause an acci-dent resulting in death or serious  
injury.
■Trailer towing precautions 
When towing, make sure that none of  
the weight limits are exceeded.  ( P.309)
■To avoid accident or injury
●Vehicles with compact spare tire: Do not tow a trailer when the com- 
pact spare tire is installed on your  vehicle.
●Vehicles with emergency tire punc-ture repair kit:Do not tow a trailer when the tire  
installed is repaired with the emer- gency tire puncture repair kit. 

3165-1. Before driving
●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 (if enabled, Trailer 
Sway Control can also help to stabilize 
the vehicle and trailer.).
●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 appro-
priate, 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. 

3305-2. Driving procedures 
enabled, the system will turn off and the  
brake hold standby indicator light will go  off. In addition, if any of the conditions are detected while the system is holding  
the brake, a warning buzzer will sound  and a message will be shown on the multi-information display. The parking  
brake will then be set automatically.
■Brake hold function
●If the brake pedal is left released for a 
period of about 3 minutes after the  system has started holding the brake, the parking brake will be set automati- 
cally. In this case, a warning buzzer  sounds and a message is shown on the multi-information display.
●To turn the system off while the sys-tem is holding the brake, firmly  
depress the brake pedal and press  the button again.
●The brake hold function may not hold the vehicle when the vehicle is on a steep incline. In this situation, it may  
be necessary for the driver to apply  the brakes. A warning buzzer will sound and the multi-information dis- 
play will inform the driver of this situa- tion. If a warning message is shown on the multi-information display, read  
the message and follow the instruc- tions.
■When the parking brake is set auto-matically while the system is hold- 
ing the brakes 
Perform any of the following operations  to release the parking brake:
●Depress the accelerator pedal. (The parking brake will not be released  
automatically if the seat belt is not fas- tened.)
●Operate the parking brake switch with the brake pedal depressed. 
Make sure that the parking brake indica- 
tor light goes off. ( P.326)
■When an inspection at any autho- 
rized Toyota retailer or Toyota  authorized repairer, or any reliable repairer is necessary 
When the brake hold standby indicator  (green) does not illuminate even when the brake hold switch is pressed with the  
brake hold system operating conditions  met, the system may be malfunctioning. Have the vehicle inspected at any  
authorized Toyota retailer or Toyota  authorized repairer, or any reliable repairer.
■If “Brake Hold Malfunction Press  
Brake to Deactivate Visit Your  Dealer” or “Brake Hold Malfunction Visit Your Dealer” is displayed on  
the multi-information display 
The system may be malfunctioning.  Have the vehicle inspected by any  
authorized Toyota retailer or Toyota  authorized repairer, or any reliable repairer.
■Warning messages and buzzers 
Warning messages and buzzers are  used to indicate a system malfunction or to inform the driver of the need for cau- 
tion. If a warning message is shown on  the multi-information display, read the message and follow the instructions.
■If the brake hold operated indicator  
flashes

WARNING
■Limitations of the pre-collision  system
●The driver is solely responsible for safe driving. Always drive safely, taking care to observe your sur- 
roundings.  Do not use the pre-collision system instead of normal braking opera- 
tions under any circumstances.  This system will not prevent colli-sions or lessen collision damage or  
injury in every situation. Do not  overly rely on this system. Failure to do so may lead to an accident,  
resulting in death or serious injury.
●Although this system is designed to 
help avoid a collision or help reduce  the impact of the collision, its effec-tiveness may change according to  
various conditions, therefore the  system may not always be able to achieve the same level of perfor- 
mance.  Read the following conditions care-fully. Do not overly rely on this sys- 
tem and always drive carefully. 
• Conditions under which the system  may operate even if there is no pos- 
sibility of a collision:  P.359 
• Conditions under which the system  may not operate properly:  P.360
●Do not attempt to test the operation  of the pre-collision system yourself. 
Depending on the objects used for  testing (dummies, cardboard objects imitating detectable objects,  
etc.), the system may not operate  properly, possibly leading to an accident.
■Pre-collision braking
●When the pre-collision braking  
function is operating, a large  amount of braking force will be applied.
●If the vehicle is stopped by the operation of the pre-collision brak-ing function, the pre-collision brak- 
ing function operation will be  canceled after approximately 2 sec-onds. Depress the brake pedal as  
necessary.
●The pre-collision braking function 
may not operate if certain opera- tions are performed by the driver. If the accelerator pedal is being  
depressed strongly or the steering  wheel is being turned, the system may determine that the driver is tak- 
ing evasive action and possibly pre- vent the pre-collision braking function from operating.
●In some situations, while the pre-collision braking function is operat- 
ing, operation of the function may  be canceled if the accelerator pedal is depressed strongly or the steer- 
ing wheel is turned and the system  determines that the driver is taking evasive action.
●If the brake pedal is being depressed, the system may deter- 
mine that the driver is taking eva- sive action and possibly delay the operation timing of the pre-collision  
braking function.
■When to disable the pre-colli-
sion system 
In the following situations, disable the  system, as it may not operate prop- 
erly, possibly leading to an accident  resulting in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing another vehicle
●When transporting the vehicle via truck, boat, train or similar means of  
transportation
●When the vehicle is raised on a lift 
with the hybrid system on and the  tires are allowed to rotate freely

■Enabling/disabling the pre-col- 
lision system 
The pre-collision system can be  
enabled/disabled on the   screen  
( P.186) of the multi-information  
display.
The system is automatically enabled  
each time the power switch is turned to  
ON.
If the system is disabled, the PCS  
warning light will turn on and a  
message will be displayed on the  
multi-information display.
■Changing the pre-collision  
warning timing 
The pre-collision warning timing  
can be changed on the   screen  
( P.186) of the multi-information  
display.
The warning timing setting is retained  
when the power switch is turned to 
OFF. However, if the pre-collision sys-
tem is disabled and re-enabled, the 
operation timing will return to the 
default setting (middle).

WARNING
■Before using LTA system
●Do not rely solely upon the LTA  
system. The LTA system does not  automatically drive the vehicle or reduce the amount of attention that  
must be paid to the area in front of  the vehicle. The driver must always assume full responsibility for driving  
safely by paying careful attention to  the surrounding conditions and operating the steering wheel to cor- 
rect the path of the vehicle. Also,  the driver must take adequate breaks when fatigued, such as from  
driving for a long period of time.
●Failure to perform appropriate driv-
ing operations and pay careful  attention may lead to an accident, resulting in death or serious injury.
●When not using the LTA system, use the LTA switch to turn the sys- 
tem off.
■Situations unsuitable for LTA 
system 
In the following situations, use the  LTA switch to turn the system off.  
Failure to do so may lead to an acci- dent, resulting in death or serious injury.
