If the engine will not start
If the engine still does not start after following the correct starting
procedure ( →P. 158) or releasing the steering lock ( →P. 159), confirm
the following points.
■ The engine will not start even when the starter motor oper-
ates normally.
One of the following may be the cause of the problem.
● There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle. ( →P. 100)
Flex-fuel vehicles: The type of fuel may be different. When
refueling, add the same type of fuel, if available.
After adding a different type of fuel, the engine may run
roughly and driving performance may be reduced for a while
when the engine is first started. In this case, wait until the
engine runs normally.
● The engine may be flooded.
Try to restart the engine once more following correct starting
procedures.
● There may be a malfunction in the engine immobilizer system.
(→ P. 105)
■ The starter motor turns over slowly, the interior lights and
headlights are dim, or the hor n does not sound or sounds at
a low volume.
One of the following may be the cause of the problem.
● The battery may be discharged. ( →P. 501)

■ Avoiding a discharged battery
●Turn off the headlights and the audio system while the engine is turned
off.
● Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic, etc.
■ When the battery is removed or discharged
Flex-fuel vehicles: The information re corded in the computer will be cleared,
which may cause the engine to run roughly and reduce driving performance
for a while when the engine is first started. In this case, wait until the engine
runs normally.
If the vehicle is running on E85, the engine may stall. In this case, restart the
engine, repeatedly if necessary.
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
Start the engine of the second vehicle. Increase the engine
speed slightly and maintain at that level for approximately 5
minutes to recharge the battery of your vehicle.
Maintain the engine speed of the second vehicle and start
the vehicle’s engine.
Once the vehicle’s engine has started, remove the jumper
cables in the exact reverse order in which they were con-
nected.
Once the engine starts, have th e vehicle checked at your Toyota
dealer as soon as possible.
