Emergency start function (vehicles with a smart key 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.
Shift the shift lever to P.
Turn the “ENGINE START STOP” switch to ACCESSORY
mode.
Press and hold the “ENGINE START STOP” switch for about
15 seconds while depressing the brake pedal firmly.
Even if the engine can be start ed using the above steps, the system
may be malfunctioning. Have the vehicle inspected by your Toyota
dealer.
■ 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. 786)
● There may be a malfunction in the steering lock system (vehi-
cle with a smart key system).
Contact your Toyota dealer if the problem cannot be repaired, or if
repair procedures are unknown.

If the shift lever cannot be shifted from P
If the shift lever cannot be shifted with your foot on the brake pedal,
there may be a problem with the shift lock system (a system to pre-
vent accidental operation of the shift lever). Have the vehicle
inspected by your Toyo ta dealer immediately.
The following steps may be used as an emergency measure to
ensure that the shift lever can be shifted:
Set the parking brake.
Vehicles without a smart ke y system: Turn the engine
switch to the “ACC” position.
Vehicles with a smart key system: Turn the “ENGINE
START STOP” switch to ACCESSORY mode.
Depress the brake pedal.
Pry the cover up with a flat-
head screwdriver or equiva-
lent tool.
Press the shift lock override
button.
The shift lever can be shifted
while the button is pressed.

Stopping the engine
Shift the shift lever to P and press the “ENGINE START STOP” switch as
you normally do when stopping the engine.
■ Replacing the key battery
As this above procedure is a temporary measure, it is recommended that the
electronic key battery be replaced immediately when the battery depletes.
(P. 709)
■ Alarm (if equipped)
Using the mechanical key to lock the doors will not set the alarm system.
If a door is unlocked using the mechanical key when the alarm system is set,
the alarm may be triggered. ( P. 162)
■ Changing “ENGINE START STOP” switch modes
Within 10 seconds of the buzzer sounding, release the brake pedal and
press the “ENGINE START STOP” switch.
The engine does not start and modes will be changed each time the switch
is pressed. ( P. 231)
