Driving
Make sure that the parking brake is set and shift the shift lever to D.
Gently depress the accelerator pedal.
Release the parking brake.
■When starting off on a uphill (vehicles  with a hill-start assist control sys-
tem)
The hill-start assist control is available. ( P. 297)
■ Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the win-
dows may become fogged-up, and the road will be slippery.
● Drive carefully when it starts to rain, because the road surface will be espe-
cially slippery.
● Refrain  from  high  speeds  when  driving  on  an  expressway  in  the  rain,
because there may be  a layer of  water  between the tires  and  the road sur-
face, preventing the steering and  brakes from operating properly.
■ Engine speed while driving
In the following conditions, the engine speed may become high while driving. 
This is due to automatic up-shifting control or down-shifting implementation to
meet driving conditions. It does not indicate sudden acceleration.
●The vehicle is judged to be driving uphill or downhill
● When the accelerator pedal is released
■ Breaking in your new Toyota
To extend the life of the vehicle, observing the following precautions is recom-
mended:
●For the first 200 miles (300 km):
Avoid sudden stops.
● For the first 500 miles (800 km):
Do not tow a trailer.
● For the first 1000 miles (1600 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.
■ Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake
system needs bedding-down of the brake shoes periodically or whenever the
parking brake shoes and/or drum are replaced. Have your Toyota dealer per-
form the bedding down operation.

4-6. Driving tips
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions.
●Park  the  vehicle  and  move  the  shift  lever  to  P  without  setting  the
parking brake. The parking brake may freeze up, preventing it from
being  released.  If  the  vehicle  is  parked  without  setting  the  parking
brake, make sure block the wheels.
Failure to do so may be dangerous  because it may cause the vehi-
cle to move unexpectedly, pos sibly leading to an accident.
● If  the  vehicle  is  parked  without  setting  the  parking  brake,  confirm
that the shift lever cannot be moved out of P
*.
*: The  shift  lever  will  be  locked  if  it  is  attempted  to  be  shifted  from  P  to  any
other position without depressing the brake pedal. If the shift lever can be
shifted from P, there may be a problem with the shift lock system. Have the
vehicle inspected by your Toyota dealer immediately.
Use the tire chains of correct size and type.
Use  SAE  Class  “S”  type  radial  tire  chains,  with  the  exception  of  radial
cable chains or V-bar type chains.
Regulations  regarding  the  use  of  tire  chains  vary  depending  on  loca-
tion and type of road. Al ways check local regulations before installing
chains.
■ Tire chain installation
Observe the following precautions when installing and removing chains.
●Install and remove tire chains in a safe location.
● Install tire chains on the front tires only. Do not install tire chains on the rear
tires.
● Install tire chains on front tires as tightly as possible. Retighten chains after
driving 1/4 - 1/2 mile (0.5 - 1.0 km).
● Install tire chains following the instructions provided with the tire chains.

WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing  to  do  so  may  result  in  a  loss  of  vehicle  control  and  cause  death  or
serious injury.
●Use tires of the specified size.
● 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
Observe the following precautions to reduce the risk of accidents.
Failing  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.
● 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  Toyota  dealers  or  legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
■ Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.

■Tire types
●Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Since summer tires do not have the same
traction  performance  as  snow  tires,  summer  tires  are  inadequate  for
driving  on  snow-covered  or  icy  ro ads.  For  driving  on  snow-covered
roads or icy roads, the use of snow tires is recommended. When install-
ing snow tires, be sure  to replace all four tires.
●All season tires
All  season  tires  are  designed  to  provide  better  traction  in  snow  and  to
be  adequate  for  driving  in  most  winter  conditions,  as  well  as  for  use
year  round.  All  season  tires,  however,  do  not  have  adequate  traction
performance compared with snow tires in heavy or loose snow. Also, all
season  tires  fall  short  in  acceleration  and  handling  performance  com-
pared with summer tires in highway driving.
●Snow tires
For  driving  on  snow-covered  roads  or  icy  roads,  we  recommend  using
snow  tires.  If  you  need  snow  tires,  select  tires  of  the  same  size,  con-
struction  and  load  capacity  as  the  or iginally  installed  tires.  Since  your
vehicle  has  radial  tires  as  original  equipment,  make  sure  your  snow
tires  also  have  radial  construction.  Do  not  install  studded  tires  without
first  checking  local  regulations  for  possible  restriction.  Snow  tires
should be installed on all wheels. ( P. 317)
■If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tire s as snow tires is lost.

Maintenance and care
■Situations in which the tire pressure warning system may not oper-
ate properly
The  tire  pressure  warning  system  will  be  disabled  in  the  following  condi-
tions:
(When the condition becomes normal, the system  will work properly.)
●If  tires  not  equipped  with  tire  pressure  warning  valves  and  transmitters
are used.
●If the ID code on the tire pressure warning valves and transmitters is not
registered in the tire pressure warning computer.
●If  the  tire  inflation  pressure  is  73  psi  (500  kPa,  5.1  kgf/cm2  or  bar)  or
higher.
The tire pressure warning system may be disabled in the following condi-
tions:
(When the condition be comes normal, the system  will work properly.)
●If electronic devices or facilities using similar radio wave frequencies are
nearby.
●If a radio set at similar frequencies is in use in the vehicle.
●If a window tint that affects the radio wave signals is installed.
●If  there  is  a  lot  of  snow  or  ice  on  th e  vehicle,  in  particular  around  the
wheels or wheel housings.
●If non-genuine Toyota wheels are used. (Even if you use Toyota wheels,
the tire pressure warning system may not work properly with some types
of tires.)
●If tire chains are used.
■Initializing the tire pressure warning system
Initialize the system  with the tire infl ation  pressure adjusted to  the  speci-
fied level.
■If you press the tire pressure warning reset switch accidentally
If initialization is perform ed, adjust the tire inflation pressure to the speci-
fied level and initialize the tire pressure warning system again.
■When the initialization of  the tire pressure warning system has failed
Initialization can be completed in a few minutes.  However, in the following
cases, the settings ha s not been recorded and  the system will not operate
properly. If repeated attempts to record  tire inflation pressure settings are
unsuccessful, have the vehicle in spected by your Toyota dealer.
●When operating the tire pressure wa rning reset switch, the tire pressure
warning light does not blink 3 times. 
●After driving for a certain period of  time since the initialization has been
completed, the warning light comes on after blinking for 1 minute.

Maintenance and care
Wheels
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width and
inset
*.
Replacement wheels are available at your Toyota dealer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
● Use  only  Toyota  wheel  nuts  and  wrenches  designed  for  use  with
your aluminum wheels.
● When  rotating,  repairing  or  changi ng  your  tires,  check  that  the
wheel nuts are still tight after  driving 1000 miles (1600 km).
● Be  careful  not  to  damage  the  aluminum  wheels  when  using  tire
chains.
● Use only Toyota genuine balance weights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.
■When replacing wheels
The  wheels  of  your  vehicle  are  equipped  with  tire  pressure  warning
valves  and  transmitters  that  allow  the  tire  pressure  warning  system  to
provide advanced warning in the event of a loss in tire inflation pressure.
Whenever  wheels  are  replaced,  tire  pressure  warning  valves  and  trans-
mitters must be installed. ( P. 497)
If a wheel is bent, cracked or  heavily corroded, it should be
replaced.
Otherwise, the tire may separate from the wheel or cause a loss
of handling control.
