■Sounds and vibrations caused by the ABS, brake assist, VSC, TRAC and
hill-start assist control systems
●A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine is started or just after the vehicle
begins  to  move.  This  sound  does  not  indicate  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 also after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the 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.
■Active Cornering Assist operation sounds and vibrations
When  the Active  Cornering Assist  is  operated,  operation  sounds and  vibra-
tions may be generated from the brake system, but this is not a malfunction.
■Automatic reactivation of TRAC and VSC systems
After  turning  the  TRAC  and  VSC  systems  off,  the  systems  will  be  automati-
cally re-enabled in the following situations:
●When the engine switch is turned off
●If  only  the  TRAC  system  is  turned  off,  the  TRAC  will  turn  on  when  vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.
■Operating conditions of Active Cornering Assist
The system operates when the following occurs.
●TRAC/VSC can operate
●The driver is attempting to accelerate while turning
●The system detects that the vehicle is sliding to the outer side
●The brake pedal is released
■Secondary Collision Brake operating conditions
The  system  operates  when  the  SRS  airbag  sensor  detects  a  collision  while
the vehicle is in motion.
However, the system does not operate in any of the following situations.
●The vehicle speed is below 6 mph (10 km/h)
●Components are damaged

3144-5. Using the driving support systems
■Secondary Collision Brake automatic cancellation
The system is automatically canceled in any of the following situations.
●The vehicle speed drops below approximately 6 mph (10 km/h)
●A certain amount of time elapses during operation
●The accelerator pedal is depressed a large amount
■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.

WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents. 
Failure  to  do  so  may  result  in  a  loss  of  vehicle  control  and  cause  death  or
serious injury.
●Use tires of the size specified.
●Maintain the recommended level of air pressure.
●Do  not  drive  in  excess  of  75  mph  (120  km/h),  regardless  of  the type  of
snow tires being used.
●Use snow tires on all, not just some wheels.
■Driving with tire chains (vehicles with 17-inch tires)
Observe the following precautions to reduce the risk of accidents. 
Failure  to  do  so  may  result  in  the  vehicle  being  unable  to  be  driven  safely,
and may cause death or serious injury.
●Do not drive in excess of the speed limit specified for the tire chains being
used, or 30 mph (50 km/h), whichever is lower.

3265-1. Using the air conditioning system and defogger
■When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehi-
cle after closing the windows, it is recommended that the air intake mode be
set to outside air mode and the fan speed to any setting except off.
■Outside/recirculated air mode
●Setting to the recirculated air mode temporarily is recommended in prevent-
ing dirty air from entering the vehicle interior and helping to cool the vehicle
when the outside air temperature is high.
●Outside/recirculated  air  mode  may  automatically  switch  depending  on  the
temperature setting or the inside temperature. 
■When the outside temperature exceeds 75°F (24°C) and the air condition-
ing system is on
●In order to reduce the air conditioning power consumption, the air condition-
ing system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
●Recirculated air mode is selected as a default mode when the engine switch
is turned to IGNITION ON mode.
●It is possible to switch to outside air mode at any time by pressing  .
■When the outside temperature is low
The dehumidification function may not operate even when   is pressed.
■Operation of the air conditioning system in Eco drive mode
●In  the  Eco  drive  mode,  “ECO”  is  displayed  on  the  air  conditioning  screen
and the air conditioning system is controlled as follows to prioritize fuel effi-
ciency:
• Engine  speed  and  compressor  operation  controlled  to  restrict  heating/
cooling capacity
• Fan speed restricted when automatic mode is selected
●To improve air conditioning performance, perform the following operations:
• Adjust the fan speed
• Turn off Eco drive mode
■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air mode.
●During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
●To reduce potential odors from occurring:
• It  is  recommended  that  the  air  conditioning  system  be  set  to  outside  air
mode prior to turning the vehicle off.
• The  start  timing  of  the  blower  may  be  delayed  for  a  short  period  of  time
immediately  after  the  air  conditioning  system  is  started  in  automatic
mode.

WARNING
■To prevent the windshield from fogging up
●Do  not  use    during  cool  air  operation  in  extremely  humid  weather.
The  difference  between  the  temperature  of  the  outside  air  and  that  of  the
windshield can cause the outer surface of the windshield to fog up, block-
ing your vision.
■To prevent burns
Do not touch the rear view mirror surfaces when the outside rear view mirror
defoggers are on.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.
■When repairing/replacing parts of the air conditioning system
Have repair/replacement performed by your Toyota dealer.
When a part of the air conditioning system, such as the evaporator, is to be
replaced, it must be replaced with a new one.
●Do not place anything on the instrument
panel  which  may  cover  the  air  outlets.
Otherwise,  air  flow  may  be  obstructed,
preventing  the  windshield  defoggers
from defogging.
