Emergency start function (vehicles with smart entry & start system)
When the engine does not start, the following steps can be used as
an interim measure to start the engine if the “ENGINE START STOP”
switch is functioning normally.
Set the parking brake.
Put the shift lever in P (Multidrive) or N (manual transmission).
Set the “ENGINE START STOP” switch to the ACCESSORY
mode.
Vehicles with a Multidrive: Press and hold the “ENGINE
START STOP” switch for about 15 seconds while depressing
the brake pedal firmly.
Vehicles with a manual transmission: Press and hold the
“ENGINE START STOP” switch for about 15 seconds while
depressing the brake pedal firmly and also depressing the
clutch pedal.
Even if the engine can be started using the above steps, the system
may be malfunctioning. Have the vehicle checked by any authorized
Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
The starter motor does not turn over, the interior lights and
headlights do not turn on, or the horn does not sound.
One of the following may be the cause of the problem.
One or both of the battery terminals may be disconnected.
The battery may be discharged. (P. 430)
There may be a malfunction in the steering lock system (vehi-
cles with smart entry & start system).
Contact any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional, if the problem cannot be
repaired, or if repair procedures are unknown.

432 5-2. Steps to take in an emergency
iQ_WE_74014E
Starting the engine when the battery is discharged (vehicles with a
Multidrive)
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 vehicle battery is removed or discharged
Any data stored in the computer will be erased. When the vehicle battery
is discharged, have the vehicle checked at any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
Vehicles with alarm: Make sure that the key is not inside the vehicle
when recharging or replacing the battery. The key may be locked in the
vehicle if the alarm is activated. (P. 120)
Reminders when the vehicle battery is discharged (vehicles with smart
entry & start system)
When the doors are attempted to be unlocked via the smart entry & start
system just after the vehicle battery has been discharged, it may fail. If
the doors cannot be unlocked, unlock the doors using a wireless remote
controller or a mechanical key.
The first engine start after the battery has been discharged may fail.
However, the engine should start after the second attempt, so it is not a
malfunction.
Once the engine starts, have the vehicle checked at any autho-
rized Toyota dealer or repairer, or another duly qualified and
equipped professional, as soon as possible.
