When trouble arises
RX350/RX350L_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 componen ts when the vehicle is running at a low
speed for an extended period , such as in heavy traffic.■
When removing the battery terminals
When the battery terminals are removed, the information stored in the ECU is cleared.
Before removing the battery termin als, contact your Lexus dealer.■
Charging the battery
The electricity stored in the battery will disc harge gradually even when the vehicle is not
in use, due to natural discharge and the draini ng effects of certain 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 the battery is removed or discharged ●
In some cases, it may not be possible to un lock the doors using the smart access system
with push-button start when the battery is discharged. Use the wireless remote control
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 switch mode is memorized by the vehicle. When the battery is recon-
nected, 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 discharged, be
especially careful when reconnecting the battery. ●
The power back door must be initialized. (  P. 138)■
When replacing the battery ●
Use a battery with the same case size as the previous battery and an equivalent 20
hour rate capacity (20HR) or greater.
• If the sizes differ, the battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehicle is not
used is a short time, the battery may discharge and the engine may not be able to
start. ●
For details, consult your Lexus dealer.
