WARNING
■Caution regarding the use of windshield wipers in “AUTO” mode
The windshield wipers may operate unexpectedly if the sensor is touched or
the  windshield  is  subject  to  vibration  in  “AUTO”  mode.  Take  care  that  your
fingers etc. do not become caught in the windshield wipers.
■ Caution regarding the use of washer fluid
When  it  is  cold,  do  not  use  the  washer  fluid  until  the  windshield  becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
NOTICE
■When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■ When the washer fluid tank is empty
Do  not  operate  the  switch  continually  as  the  washer  fluid  pump  may  over-
heat.
■ When a nozzle becomes blocked
In this case, contact your Toyota dealer. 
Do not try to clear it with a pin or other object. The nozzle will be damaged.

Winter driving tips
●Use  fluids  that  are  appropriate  to  the  prevailing  outside  tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician ins pect the condition of the battery.
● 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  chains  match
the size of the tires.
Perform the following accordin g to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is frozen.
Pour  warm  water  over  the  frozen  area  to  melt  the  ice.  Wipe  away
the water immediately to prevent 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 ice or snow that may have accu-
mulated  on  the  exterior  lights,  ve hicle’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 man-
ner appropriate to the prevailing weather conditions.
