IN CASE OF AN EMERGENCY
308
IF YOUR VEHICLE WILL NOT
START
(a) Simple checks
Before making these checks, make sure you have followed
the correct starting procedure instructions in ”How to start the
engine” on page 261 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 ”Keys” on page
10.
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 ”(c) Jump starting” 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
”Foreword”.)
NOTICE
Do not pull– or push–start the vehicle. It may damage the
vehicle or cause a collision when the engine starts. Also
the three–way catalytic converter may overheat and
become a fire hazard.
If the engine turns over at its normal speed but will not
start –
1. The engine may be flooded because of repeated cranking.
See ”(b) Starting a flooded engine” 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 ”Foreword”.)
(b) Starting a flooded engine
If the engine will not start, your engine may be flooded
because of repeated cranking.
If this happens, turn the key to ”START” with the accelerator
pedal held down. Continue this operation for 30 seconds and
then stop cranking. Then try starting the engine with your foot
off the accelerator pedal.
If the engine does not start after 30 seconds of cranking,
release the key, wait a few minutes and try again.
If the engine still will not start, it needs adjustment or repair.
Call a Lexus dealer. Roadside Assistance or Customer
Service Assistance. (See ”Foreword”.)
