Electronic Brake Force Distribution System Warning
If  the  electronic  brake  force  distribution  control  unit  deter-
mines  that  some  components  are  operating  incorrectly,
the  control  unit  may  illuminate  the  brake  system  warning
light  and  the ABS  warning  light  simultaneously. The  prob-
lem  is  likely  to  be  the  electronic  brake  force  distribution
system.
Charging System Warning Light
If  the  warning  light  illuminates  while  driving,  it  indicates  a
malfunction of the alternator or of the charging system. 
Drive to the side of the road and park off the right-of-way.
Consult your Toyota dealer. 
Engine Oil Warning LightThis warning light indicates low engine oil pressure.
If  the  light  illuminates  or  the  warning  indication  is  dis-
played while driving:
Drive  to  the  side  of  the  road  and  park  off  the  right-of-
way on level ground.
Turn  off  the  engine  and  wait  5  minutes  for  the  oil  to
drain back into the oil pan.
Inspect  the  engine  oil  level  P.  397.  If  it’s  low,  add  the
appropriate  amount  of  engine  oil  while  being  careful
not to overfill.
Start the engine and check the warning light.
If the light remains illuminated even though the oil level is
normal  or  after  adding  oil,  stop  the  engine  immediately
and have your vehicle towed to your Toyota dealer.

■Power Steering Malfunction Indicator Light
●If  the  indicator  light  illuminates/flashes,  the  power  steering  will  not  operate
normally. If this happens, the steering wheel can still be operated, however,
the  operation  may  feel  heavy  compared  to  normal,  or  the  steering  wheel
could vibrate when turning.
● Repeatedly  jerking  the  steering  wheel  left  and  right  while  the  vehicle  is
stopped or moving extremely slowly will cause the power steerin g system to
go  into  protective  mode  which  will  make  the  steering  feel  heavy ,  but  this
does not indicate a problem. If this occurs, park the vehicle safely and wait
several minutes for the system to return to normal.
WARNING

your Toyota dealer to have the brakes inspected as soon as poss ible
Driving with the brake system warning light illuminated is dang erous. It indi-
cates that your brakes may not work at all or that they could c ompletely fail

minated simultaneously is dangerous.
When both lights are illuminated, the rear wheels could lock mo re quickly in
an emergency stop than under normal circumstances.
