4RUNNER_U
■After recharging/reconnecting the battery (vehicles with smart key sys-
tem)
● Unlocking the doors using the smart key system may not be possible
immediately after disconnecting the battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the doors.
● Start the engine with the “ENGINE START STOP” switch in ACCES-
SORY mode. The engine may not start with the “ENGINE START STOP”
switch turned OFF. However, the engine will operate normally from the
second attempt.
● The “ENGINE START STOP” switch mode is recorded by the vehicle. If
the battery is reconnected, the vehicle will return the “ENGINE START
STOP” switch mode to the status it was in before the battery was discon-
nected. Make sure to turn off the engine before disconnect the battery.
Take extra care when connecting the battery if the “ENGINE START
STOP” switch mode prior to discharge is unknown.
If the system will not start even after multiple attempts, contact your Toyota
dealer.
CAUTION
■ Chemicals in the battery
Batteries contain poisonous and corrosive sulfuric acid and may produce
hydrogen gas which is flammable and explosive. To reduce the risk of death
or serious injury, take the following precautions while working on or near the
battery:
● Do not cause sparks by touching the battery terminals with tools.
● Do not smoke or light a match near the battery.
● Avoid contact with eyes, skin and clothes.
● Never inhale or swallow electrolyte.

5-2. Steps to take in an emergency
4RUNNER_U
■
Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■ To prevent battery discharge
● Turn off the headlights and the audio system while the engine is 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.
■ Precautions when the battery is di scharged (vehicles with a smart key
system)
● In some cases, it may not be possible to unlock the doors using the smart
key system when the battery is discharged. Use the wireless remote con-
trol or the mechanical key to lock or unlock the doors.
● The engine may not start on the first attempt after the battery has
recharged but will start normally after the second attempt. This is not a
malfunction.
● The “ENGINE START STOP” switch mode is memorized by the vehicle.
When the battery is reconnected, the system will return to the mode it
was in before the battery was discharged. Before disconnecting the bat-
tery, turn the “ENGINE START STOP” switch off.
If you are unsure what mode the “ENGINE START STOP” switch was in
before the battery discharged, be especially careful when reconnecting
the battery.
