IF YOUR VEHICLE WILL NOTSTART
(a) Simple checks
Before making these checks, make sure you have
followed the correct starting procedure instructions in
ºHow to start the engineº on page 280 and that you have
sufficient fuel. Since your vehicle is equipped with the
engine immobiliser system, also check whether the
other keys will start the engine. If they work, your key
may be broken. Have the key checked at your Lexus
dealer. If none of your keys work, the system is possibly
broken. Call your Lexus dealer. See ºKeysº on page 9.
If the engine is not turning over or is turning over too
slowly ±
1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior
light.
3. If the light is out, dim or goes out when the starter is
cranked, the battery is discharged. You may try jump
starting. See º(c) Jump startingº for further instruction.
If the light is O.K., but the engine still will not start, it
needs adjustment or repair. Call a Lexus dealer,
Roadside Assistance or Customer Service Assistance.
(See ºForewordº.)

cranking. See º(b) Starting a flooded engineº for further
instructions.
2. If the engine still will not start, it needs adjustment or
repair. Call a Lexus dealer, Roadside Assistance or
Customer Service Assistance. (See ºForewordº.)
