operate properly due to a sensor malfunction. Have the vehicle  inspected
at your Toyota dealer.
● When  using  a  high-pressure  washer  to  wash  the  vehicle,  do  not  s pray
water  directly  on  the  sensors.  The  sensors  may  not  function  pro perly  if
subjected to an impact from strong water pressure.
● When  using  steam  to  wash  the  vehicle,  do  not  direct  steam  too  c lose  to
the sensors. The sensors may not function properly if subjected to steam.

Winter driving tips
●Use  fluids  that  are  appropriate  t o  the  prevailing  outside  tempera-
tures.  • Engine oil
• Engine/power control unit coolant
• Washer fluid
● Have  a  service  technician  inspect  the  condition  of  the  12-volt  bat-
tery.
● Have the vehicle fitted with four snow tires or purchase a set  of tire
chains for the  front tires. 
Ensure  that  all  tires  are  the  same  size  and  brand,  and  that  cha ins  match
the size of the tires.
Perform the following accordi ng to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is fr ozen.
Pour  warm  water  over  the  frozen  area  to  melt  the  ice.  Wipe  away
the water immediately to p revent it from freezing. 
● To  ensure  proper  operation  of  the  climate  control  system  fan,
remove  any  snow  that  has  accumulated  on  the  air  inlet  vents  in
front of the windshield. 
● Check for and remove any excess ic e or snow that may have accu-
mulated  on  the  exterior  lights,  vehicle’s  roof,  chassis,  around  the
tires or on the brakes.
● Remove  any  snow  or  mud  from  the  bottom  of  your  shoes  before
getting in the vehicle.
Carry  out  the  necessary  preparations  and  inspections  before
driving  the  vehicle  in  winter. Always  drive  the  vehicle  in  a  ma n-
ner appropriate to the prevailing weather conditions.

Driving
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to roa d con-
ditions.
Park  the  vehicle  and  shift  the  shift  position  to  P  and  block  th e  wheel
under the vehicle without setting the parking brake. The parkin g brake
may  freeze  up,  preventing  it  fro m  being  released.  If  the  vehicle  is
parked  without  setting  the  parking  brake,  make  sure  to  block  th e
wheels.
Failure to do so may be dangerous because it may cause the vehi cle
to move unexpectedly, possi bly leading to an accident.
Use  the  correct  tire  chain  size   when  mounting  the  tire  chains.  Chain
size is regulated for each tire size.
Side chain
0.12 in. (3.0 mm)
1.18 in. (30.0 mm)
0.39 in. (10.0 mm)
Cross chain 0.16 in. (4.0 mm)
0.98 in. (25.0 mm)
0.55 in. (14.0 mm)
Regulations  regarding  the  use  of  tire  chains  vary  depending  on  loca-
tion and type of road. Always chec k local regulations before installing
chains.
