LS600h/LS600hL_EE(OM50G20E)
The SRS airbag and seat belt pretensioner devices in your Lexus contain explosive
chemicals. If the vehicle is scrapped with the airbags and seat belt pretensioners left
as they are, this may cause an accident such as fire. Be sure to have the systems of
the SRS airbag and seat belt pretensioner removed and disposed of by a qualified
service shop or by any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional before you scrap your vehicle.
Scrapping of your Lexus
Your vehicle contains batteries and/or accumulators. Do not discard them into
the environment but cooperate with separate collection
(Directive 2006/66/EC).

Hybrid system precautions
Take care when handling the hybrid system, as it contains a high voltage
system (about 650 V at maximum) as well as parts that become
extremely hot when the hybrid system is operating. Obey the caution
labels attached to the vehicle.

For safety and security
LS600h/LS600hL_EE(OM50G20E)
■If a warning light comes on, a warning message is displayed, or the 12-volt battery is
disconnected
The hybrid system may not start. In that case, try to start the system again. If the
“READY” indicator does not come on, contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
■Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started, refuel
the vehicle with at least enough gasoline to make the low fuel level warning light
( P. 558) go off. If there is only a small amount of fuel, the hybrid system may not be
able to start. (The minimum amount of fuel to add to make the low fuel level warning
light go out is about 13 L [3.4 gal., 2.8 Imp. gal.], when the vehicle is on a level sur-
face. This value may vary when the vehicle is on a slope.)
■Electromagnetic waves
●High voltage parts and cables on the hybrid vehicles incorporate electromagnetic
shielding, and therefore emit approximately the same amount of electromagnetic
waves as conventional gasoline powered vehicles or home electronic appliances.
●Your vehicle may cause sound interference in some third party-produced radio
parts.
■Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of the
hybrid battery (traction battery) can change in accordance with driving style and
driving conditions.
■Declaration of conformity
This model conforms to hydrogen emissions according to regulation ECE100 (Bat-
tery electric vehicle safety).

921-2. Hybrid system
LS600h/LS600hL_EE(OM50G20E)
CAUTION
■High voltage precautions
The vehicle has high voltage DC and AC systems as well as a 12-volt system. DC
and AC high voltage is very dangerous and can cause severe burns and electric
shock that may result in death or serious injury.
●Never touch, disassemble, remove or replace the high voltage parts, cables or
their connectors.
●The hybrid system will become hot after starting as the system uses high voltage.
Be careful of both the high voltage and the high temperature, and always obey
the caution labels attached to the vehicle.
●Never try to open the service plug access
hole located behind the rear seat. The ser-
vice plug is used only when the vehicle is
serviced and is subject to high voltage.

LS600h/LS600hL_EE(OM50G20E)
●Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine/power control unit coolant
•Washer fluid
●Have a service technician inspect the condition of the 12-volt battery.
●Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the rear tires.
Ensure that all tires are the specified size and brand, and that chains match the
size of the tires.
Winter driving tips

6-2. Maintenance
Scheduled maintenance should be performed at specified intervals
according to the maintenance schedule.
For details about maintenance items and schedules, refer to the “Lexus Service
Booklet” or “Lexus Warranty Booklet”.
What about do-it-yourself maintenance?
Many of the maintenance items are easy to do yourself if you have a little mechan-
ical ability and a few basic automotive tools.
Note, however, that some maintenance tasks require special tools and skills.
These are best performed by qualified technicians. Even if you’re an experienced
do-it-yourself mechanic, we recommend that repairs and maintenance be con-
ducted by any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional. Any authorized Lexus dealer or repairer will keep a
record of maintenance, which could be useful should you ever require Warranty
Service. Should you choose to select a qualified and equipped professional other
than an authorized Lexus repairer to service or maintain your vehicle, we recom-
mend that you request that a record of maintenance be kept.
Maintenance requirements
To ensure safe and economical driving, day-to-day care and regular
maintenance are essential. Lexus recommends the following mainte-
nance:
