When driving
NOTICE
nIf you hear a squealing or scraping noise (brake pad wear limit indicators)
Have your Lexus dealer check and replace the brake pads as soon as possible.
The rotor damage can result if the pads are not replaced when needed.
Front brake only: Moderate levels of the brake pad and disc wear allow enhanced
front braking power. As a result, the discs may wear more quickly than conventional
brake discs. Therefore, when replacing the brake pads, Lexus recommends that you
also have the thickness of the discs measured.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or
that of the brake discs are exceeded.
nIf you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel
firmly and gradually press the brake pedal to slow down the vehicle.
lIt may be difficult to control your vehicle.
lThe vehicle will make abnormal sounds.
lThe vehicle will behave abnormally.
Replace a flat tire with a new one. (→P. 4 0 6 )
nWhen encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the
following serious damage to the vehicle.
lEngine stalling
lShort in electrical components
lEngine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to
have your Lexus dealer check the following.
lBrake function
lChanges in quantity and quality of oil and fluid used for the engine, transmission,
transfer (AWD vehicles), differential, etc.
