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.
Vehicles with a smart key system only: Open and close any
of the doors of your vehicle with the “ENGINE START
STOP” switch off.
Maintain the engine speed of the second vehicle and start
the engine of your vehicle by turning the “ENGINE START
STOP” switch to IGNITION ON mode (vehicles with a smart
key system) or turning the engine switch to the “ON” posi-
tion (vehicles without a smart key system).
Once the vehicle’s engine has started, remove the jumper
cables in the exact reverse or der from which they were con-
nected.
Once the engine starts, have the vehicle inspected at your Toyota
dealer as soon as possible.STEP 2

■
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.
■ 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.)
■ 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.
