unable to correctly assist you in reaching the target parking s pot and may 
lead to an unexpected accident. 
• In an area that is not a parking lot 
• A parking lot that is not paved and has no parking space lines , such as 
a sand or gravel parking lot
• A parking lot that has a slope or undulations in the road 
• A frozen, snow-covered or slippery road 
• The asphalt is melting due to hot weather
• There is an obstacle between the vehicle and the target parkin g spot 
• Using tire chains or compact spare tire (if equipped) 
● Do not  use  tire  other  than that  provided  by the  manufacturer. The  system 
may  not  operate  properly.  When  replacing  tires,  contact  any  aut horized 
Toyota retailer or Toyota authorized repairer, or any reliable  repairer. 
● The system may not be able position the vehicle in the set location in the 
following situations.

WARNING
■Hill-start assist control does not operate effectively when 
● Do  not  overly  rely  on  hill-start  assist  control.  Hill-start  assist  control  may 
not operate effectively on steep inclines and roads covered wit h ice. 
● Unlike the parking brake, hill-start assist control is not intended to hold the 
vehicle  stationary  for  an  extended  period  of  time.  Do  not  attem pt  to  use 
hill-start  assist  control  to  hold  the  vehicle  on  an  incline,  as   doing  so  may 
lead to an accident. 
■ When the TRC/ABS/VSC/Trailer Sway Control is activated 
The slip indicator light flashes. Always drive carefully. Reckl ess driving may 
cause an accident. Exercise particular care when the indicator  light flashes. 
■ When the TRC/VSC/Trailer Sway Control systems are turned off 
Be  especially  careful  and  drive  at  a  speed  appropriate  to  the  r oad  condi- 
tions. As  these  are  the  systems  to  help  ensure  vehicle  stabilit y  and  driving 
force,  do  not  turn  the  TRC/VSC/Trailer  Sway  Control  systems  off   unless 
necessary. 
Trailer Sway Control is part of the VSC system and will not ope rate if VSC is 
turned off or experiences a malfunction. 
■ Replacing tires 
Make  sure  that  all  tires  are  of  the  specified  size,  brand,  trea d  pattern  and 
total  load  capacity.  In  addition,  make  sure  that  the  tires  are  inflated  to  the 
recommended tire inflation pressure level. 
The ABS, TRC, Trailer Sway Control and VSC systems will not fun ction cor- 
rectly if different tires are installed on the vehicle.
Contact any authorized Toyota retailer or Toyota authorized rep airer, or any 
reliable repairer for further information when replacing tires  or wheels.

◆Checking tire inflation pressure 
Make  sure  to  check  the  tire  inflation  pressure  frequently.  Impr oper 
tire inflation pressure can cause poor fuel economy. 
Also, as snow tires can cause large amounts of friction, their  use on 
dry roads can lead to poor fuel economy. Use tires that are app ro- 
priate for the season.
◆Luggage 
Carrying heavy luggage will lead to poor fuel economy. Avoid ca rry- 
ing unnecessary luggage. Installing a large roof rack will also  cause 
poor fuel economy.
◆Warming up before driving 
Since  the  gasoline  engine  starts  up  and  cuts  out  automatically 
when  cold,  warming  up  the  engine  is  unnecessary.  Moreover,  fre- 
quently  driving  short  distances  will  cause  the  engine  to  repeat edly 
warm up, which can lead to excess fuel consumption.

WARNING
■Driving with snow tires 
Observe the following precautions to reduce the risk of acciden ts.  
Failure  to  do  so  may  result  in  a  loss  of  vehicle  control  and  ca use  death  or 
serious injury. 
● Use tires of the specified size. 
● Maintain the recommended level of air pressure. 
● Do not drive at speeds in excess of the speed limit or the speed limit spec- 
ified for the snow tires being used. 
● Use snow tires on all, not just some wheels. 
■ Driving with tire chains 
Observe the following precautions to reduce the risk of acciden ts.  
Failure  to  do  so  may  result  in  the  vehicle  being  unable  to  be  d riven  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 50 km/h (30 mph), whichever is lower. 
● Avoid driving on bumpy road surfaces or over potholes. 
● Avoid  sudden  acceleration,  abrupt  steering,  sudden  braking  and shifting 
operations that cause sudden engine braking. 
● Slow down sufficiently before entering a curve to ensure that vehicle con- 
trol is maintained.
NOTICE
■ Repairing or replacing snow tires 
Request  repairs  or  replacement  of  snow  tires  from  any  authorize d  Toyota 
retailer  or  Toyota  authorized  repairer,  or  any  reliable  repaire r  or  legitimate 
tire retailers. 
This is because the removal and attachment of snow tires affect s the opera- 
tion of the tire pressure warning valves and transmitters. 
■ Fitting tire chains 
The tire pressure warning valves and transmitters may not funct ion correctly 
when tire chains are fitted.

WARNING
The  engine  compartment  contains  many  mechanisms  and  fluids  that  may 
move suddenly, become hot, or become electrically energized. To  avoid death 
or serious injury, observe  the following precautions. 
■ When working on the engine compartment 
● Make  sure  that  the  “ACCESSORY”  or  “IGNITION  ON”  on  the  multi-infor- 
mation display and the “READY” indicator are both off. 
● Keep hands, clothing and tools away from the moving fan. 
● Be  careful  not  to  touch  the  engine,  power  control  unit,  radiator,  exhaust 
manifold,  etc.,  right  after  driving  as  they  may  be  hot.  Oil  and  other fluids 
may also be hot. 
● Do not leave anything that may burn easily, such as paper and rags, in the 
engine compartment. 
● Do not smoke, cause sparks or expose an open flame to fuel or the 12-volt 
battery. Fuel and 12-volt battery fumes are flammable. 
● Be extremely cautious when working on the 12-volt battery. It contains poi- 
sonous and corrosive sulfuric acid. 
● Take care because brake fluid can harm your hands or eyes and damage 
painted  surfaces.  If  fluid  gets  on  your  hands  or  in  your  eyes,  flush  the 
affected area with clean water immediately. If you still experi ence discom- 
fort, consult a doctor. 
■ When working near the electric cooling fans or radiator grille 
Be sure the power switch is off. 
With the power switch in ON mode, the electric cooling fans may  automati- 
cally start to run if the air conditioning is on and/or the coo lant temperature 
is high. ( P. 606) 
■ Safety glasses 
Wear  safety  glasses  to  prevent  flying  or  falling  material,  flui d  spray,  etc., 
from getting in your eyes.

Your vehicle is equipped with a tire pressure warning system that uses 
tire  pressure  warning  valves  and  transmitters  to  detect  low  tir e  infla- 
tion pressure before serious problems arise. 
If  the  tire  pressure  drops  below  a  predetermined  level,  the  dri ver  is 
warned by a warning light. ( P. 686)
◆Installing tire pressure warning valves and transmitters 
When  replacing  tires  or  wheels,  tire  pressure  warning  valves  an d 
transmitters must also be installed. 
When  new  tire  pressure  warning  valves  and  transmitters  are 
installed,  new  ID  codes  must  be  registered  in  the  tire  pressure 
warning  computer  and  the  tire  pressure  warning  system  must  be 
initialized.  Have  tire  pressure  warning  valve  and  transmitter  I D 
codes registered by any authorized Toyota retailer or Toyota au tho- 
rized repairer, or any reliable repairer. ( P. 620)
◆Initializing the tire pressure warning system 
When  the  tire  size  is  changed,  the  tire  pressure  warning  system 
must be initialized. 
When the tire pressure warning system is initialized, the curre nt tire 
inflation pressure is set as the benchmark pressure.
