Ti r e v a l v e
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure using the gauge gradations.
If the tire inflation pressure is not at the recommended level, adjust the
pressure.
If you add too much air, press the center of the valve to deflate.
After completing the tire inflation pressure measurement and adjust-
ment, apply soapy water to the valve and check for leakage.
Put the tire valve cap back on.
■Tire inflation pressure check interval
You should check tire inflation pressure every two weeks, or at least once a month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
●Reduced fuel efficiency
●Reduced driving comfort and tire life
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating, have it checked by your Lexus dealer.

When trouble arises
Fuel pump shut off system (gasoline vehicles)
Follow the procedure below to restart the engine after the system is acti-
vated.
Turn the “START STOP ENGINE” switch to ACCESSORY mode or
turn it off.
Restart the engine.
To minimize the risk of fuel leakage when the engine stalls or when an
airbag inflates upon collision, the fuel pump shut off system stops the
supply of fuel to the engine.
NOTICE
■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked onto th e ground, the fuel system has been damaged
and is in need of repair. Do not restart the engine.
