6-1. Maintenance and care
Cleaning and protecting the vehicle exterior
●Working from top to bottom, liberally apply water to the vehicle body,
wheel wells and underside of the vehicle to remove any dirt and dust.
●Wash the vehicle body using a sponge or soft cloth, such as a chamois.
●For hard-to-remove marks, use car wash soap and rinse thoroughly
with water.
●Wipe away any water.
●Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle body is
cool.
■Automatic car washes
●Fold the mirrors before washing the vehicle. Start washing from the front of the
vehicle. Make sure to extend the mirrors before driving.
●Brushes used in automatic car washes may scratch the vehicle surface and harm
your vehicle’s paint.
■High pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity of the win-
dows.
●Before using the car wash, check that the fuel filler door on your vehicle is closed
properly.
■Notes for a smart access system with push-button start
If the door handle becomes wet while the electronic key is within the effective range,
the door may lock and unlock repeatedly. In that case, follow the following correc-
tion procedures to wash the vehicle:
●Place the key in a position 6 ft. (2 m) or more separate from the vehicle while the
vehicle is being washed. (Take care to ensure that the key is not stolen.)
●Set the electronic key to battery-saving mode to disable the smart access system
with push-button start. (→P. 1 2 9 )
Perform the following to protect the vehicle and mainta in it in prime
condition:

6-3. Do-it-yourself maintenance
■Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flammable
and explosive. Therefore, observe the following precautions before recharging:
●If recharging with the 12-volt battery installed on the vehicle, be sure to disconnect
the ground cable.
●Make sure the power switch on the charger is off when connecting and discon-
necting the charger cables to the 12-volt battery.
■After recharging/reconnecting the 12-volt battery
●The hybrid system may not start. Follow the procedure below to initialize the sys-
tem.Shift the shift lever to P.
Open and close any of the doors.
Restart the hybrid system.
●Unlocking the doors using the smart access system with push-button start may not
be possible immediately after reconnecting the 12-volt battery. If this happens, use
the wireless remote control or the mechanical key to lock/unlock the doors.
●Start the hybrid system with the power switch in ACCESSORY mode. The hybrid
system may not start with the power switch turned off. However, the hybrid system
will operate normally from the second attempt.
●The power switch mode is recorded by the vehicle. If the 12-volt battery is recon-
nected, the vehicle will return the power switch mode to the status it was in before
the 12-volt battery was disconnected. Make sure to turn off the power switch
before disconnect the 12-volt battery. Take extra care when connecting the 12-volt
battery if the power switch mode prior to discharge is unknown.
If the system will not start even after multiple attempts at all methods above, contact
your Lexus dealer.
