If the engine still does not start after following the correct starting
procedure ( P. 159) or releasing the steering lock (P. 160), 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. 102)
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. 107)

If the vehicle batter y is discharged
The following procedures may be used to start the engine if the
vehicle’s battery is discharged.
You can call your Toyota dealer or qualified repair shop.
If you have a set of jumper (or boo ster) cables and a second vehi-
cle with a 12-volt battery, you can jump start your Toyota following
the steps below.
Connect the jumper cables.
Positive (+) battery terminal on your vehicle
Positive (+) battery terminal on the second vehicle
Negative (-) battery terminal on the second vehicle
Connect the jumper cable to ground on your vehicle as shown in
the illustration. 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

5-2. Steps to take in an emergency
■
Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■ 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 recorded 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.)
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 the vehicle checked at your Toyota
dealer as soon as possible.
