2017 TOYOTA HIGHLANDER key battery

6428-2. Steps to take in an emergency
HIGHLANDER_U (OM0E017U)
■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 stopped.
(Vehicles with Stop & Start system: except when the engine is stopped by
the Stop & Start system.)
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
■ When recharging or replacing the battery
●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 dis-
charged. Use the wireless remote control or the mechanical key to lock or
unlock the doors.
● Vehicles with a smart key system: The engine may not start on the first
attempt after the battery has recharged but will start normally after the sec-
ond attempt. This is not a malfunction.
● Vehicles with a smart key system: The engine 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
battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.
● Vehicle with power back door: The power back door must be initialized.
(→P. 692)
● Vehicles with Stop & Start system: After the battery terminals have been dis-
connected then reconnected or the battery has been replaced, the Stop &
Start system may not automatically stop the engine for approximately 5 to
60 minutes.
■ 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.)
■ When exchanging the battery (veh icles with Stop & Start system)
Use a genuine battery specifically designed for use with a Stop & Start sys-
tem or equivalent. If an unsupported battery is used, Stop & Start system
functions may be restricted to protect the battery. Also, battery performance
may decrease and the engine may not be able to restart. Contact your Toyota
dealer for details.

Vehicle specifications
HIGHLANDER_U (OM0E017U)
■Vehicle customization
●When the smart key system is off, the entry unlock function cannot be cus-
tomized.
● When the doors remain closed after unlocking the doors and the timer act\
i-
vated automatic door lock function activates, signals will be generated in
accordance with the operation buzzer volume and operational signal (Emer-
gency flashers) function settings.
■ Changing of the power back door opening angle (if equipped)
The opening angle setting can be changed through operation of either the
power back door switch or the audio system screen.
However, if the engine switch is on and the power back door switch is used to
change the opening angle setting, the changed opening angle will not be
reflected on the audio system screen until the engine switch is turned off and
then on again.
■ When customizing on the audio system screen
Stop the vehicle in a safe place, apply the parking brake, and shift the shift
lever to P. Also, to prevent battery discharge, leave the engine running while
customizing the features.
WARNING
■ During customization
As the engine needs to be running during customization, ensure that the
vehicle is parked in a place with adequate ventilation. In a closed area such
as a garage, exhaust gases including harmful carbon monoxide (CO) may
collect and enter the vehicle. This may lead to death or a serious health
hazard.
NOTICE
■During customization
To prevent battery discharge, ensure that the engine is running while cus-
tomizing features.
