7-2. Steps to take in an emergency 
ble.
■Electric power steering system  
warning light (warning buzzer) 
When the battery charge becomes  insufficient or the voltage temporarily  
drops, the electric power steering sys- tem warning light may come on and the warning buzzer may sound.
■When the tire pressure warning  
light comes on 
Inspect the tires to check if a tire is  punctured. 
If a tire is punctured:  →P. 3 2 5 
If none of the tires are punctured: Turn the engine switch off then turn it to  
ON. Check if the tire pressure warning  light comes on or blinks.
If the tire pressure warning light blinks  
for approximately 1 minute then stays  on 
There may be a malfunction in the tire  
pressure warning system. Have the  vehicle inspected by any authorized Toyota retailer or Toyota authorized  
repairer, or any reliable repairer immedi- ately.
If the tire pressure warning light  
comes on 
1 After the temperature of the tires has  lowered sufficiently, check the infla-tion pressure of each tire and adjust  
them to the specified level. 
2 If the warning light does not turn off  even after several minutes have elapsed, check that the inflation  
pressure of each tire is at the speci- fied level and perform initialization. ( →P.282)
■The tire pressure warning light may  
come on due to natural causes 
The tire pressure warning light may  come on due to natural causes such as  
natural air leaks and tire inflation pres- sure changes caused by temperature. In this case, adjusting the tire inflation  
pressure will turn off the warning light  (after a few minutes).
■Conditions that the tire pressure  
warning system may not function  properly 
→ P. 2 8 0
WARNING
■If both the ABS and the brake  system warning lights remain on 
Stop your vehicle in a safe place  
immediately and contact any autho- rized Toyota retailer or Toyota autho-rized repairer, or any reliable repairer. 
The vehicle will become extremely  unstable during braking, and the ABS system may fail, which could cause  
an accident resulting in death or seri- ous injury.
■When the electric power steer-ing system warning light comes on 
When the light comes on yellow, the  assist to the power steering is restricted. When the light comes on  
red, the assist to the power steering is  lost and handling operations of the steering wheel become extremely  
heavy. When steering wheel operations are heavier than usual, grip the steering  
wheel firmly and operate it using more  force than usual.
■If the tire pressure warning light comes on 
Be sure to observe the following pre- 
cautions. Failure to do so could cause a loss of vehicle control and result in death or  
serious injury.
●Stop your vehicle in a safe place as 
soon as possible. Adjust the tire  inflation pressure immediately.
●Avoid abrupt maneuvering and braking.If the vehicle tires deteriorate, you  
could lose control of the steering  wheel or the brakes.

7-2. Steps to take in an emergency
When trouble arises
WARNING
●Do not touch the wheels or the area  around the brakes immediately  
after the vehicle has been driven. After the vehicle has been driven, the wheels and the area around the  
brakes may be extremely hot.  Touching these areas with hands, feet or other body parts may result  
in burns.
●Connect the valve and hose 
securely with the tire installed on  the vehicle. If the hose is not prop-erly connected to the valve, air  
leakage may occur as sealant may  be sprayed out.
●If the hose comes off the valve while inflating the tire, there is a risk that the hose will move abruptly due  
to air pressure.
●After inflation of the tire has com-
pleted, the sealant may splatter  when the hose is disconnected or some air is let out of the tire.
●Follow the operation procedure to repair the tire. If the procedures not  
followed, the sealant may spray  out.
●Keep back from the tire while it is being repaired, as there is a chance of it bursting while the repair opera- 
tion is being performed. If you  notice any cracks or deformation of the tire, turn off the compressor  
switch and stop the repair operation  immediately.
●The repair kit may overheat if oper-ated for a long period of time. Do not operate the repair kit continu- 
ously for more than 40 minutes.
●Parts of the repair kit become hot  during operation. Be careful when handling the repair kit during and  
after operation. Do not touch the  metal part around the connecting area between the bottle and com- 
pressor. It will be extremely hot.
●Do not attach the vehicle speed 
warning sticker to an area other  than the one indicated. If the sticker is attached to an area where an  
SRS airbag is located, such as the  pad of the steering wheel, it may prevent the SRS airbag from oper- 
ating properly.
●To avoid risk of burst or severe 
leakage, do not drop or damage the  bottle. Visually inspect the bottle before use. Do not use a bottle with  
shock, crack, scratch, leakage or  any other damage. In such case, immediately replace.
■Driving to spread the liquid seal-ant evenly 
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.
●Drive the vehicle carefully at a low speed. Be especially careful when turning and cornering.
●If the vehicle does not drive straight or you feel a pull through the steer- 
ing wheel, stop the vehicle and  check the following. 
• Tire condition. The tire may have  separated from the wheel. 
• Tire inflation pressure. If the tire  inflation pressure is 130 kPa (1.3  
kgf/cm2 or bar, 19 psi) or less, the  
tire may be severely damaged.
