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. Turn the ignition key to "ACC" or "LOCK" and try starting the
engine again.
2. If the engine will not start, the engine may be flooded
because of repeated cranking. See "(b) Starting a flooded
engine" for further instructions.
3. If 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 crank for more than 30 seconds at a time. This
may overheat the starter and wiring systems.
IN CASE OF AN EMERGENCY
(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 fully depressed. 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".)
