Maintenance and care
LS600h/LS600hL_EE(OM50G20E)
■Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to main-
tain the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge or
brush to apply the foam. Rub in overlapping circles. Do not use water. Wipe dirty sur-
faces and let them dry. Excellent results are obtained by keeping the carpet as dry as
possible.
■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the
belts periodically for excessive wear, fraying or cuts.
CAUTION
■Water in the vehicle
●Do not splash or spill liquid in the vehicle, such as on the floor, in the hybrid bat-
tery (traction battery) air vents, and in the trunk.
Doing so may cause the hybrid battery, electrical components, etc. to malfunc-
tion or catch fire.
●Do not get any of the SRS components or wiring in the vehicle interior wet.
( P. 51)
An electrical malfunction may cause the airbags to deploy or not function prop-
erly, resulting in death or serious injury.
■Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect off the
windshield, obstructing the driver’s view and leading to an accident, resulting in
death or serious injury.
■Cleaning the leather areas of the instrument panel
Do not use any protective agents (coatings etc). Doing so may cause the instru-
ment panel to reflect onto the windshield, obstructing the front view and possibly
causing an accident.

■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 one or both of the following procedures:
●After opening and closing the driver’s door, wait 10 seconds and then attempt to
start the hybrid system. (If the system does not start the first time, repeat the proce-
dure.)
●With the shift lever in P and the power switch off, open and close any door and then
attempt to start the hybrid system.
If the system will not start even after multiple attempts at both methods, contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional.
