When driving NOTICE■
To prevent water damage
Take all necessary safety measures to ensure that water damage to the hybrid bat-
tery, hybrid system or other components does not occur. ●
Water entering the engine compartment may cause severe damage to the hybrid
system. Water entering the interior may cause the hybrid battery stowed under
the rear seats to short circuit.●
Water entering the hybrid transmission will cause deterioration in transmission
quality. The malfunction indicator may come on, and the vehicle may not be driv-
able.●
Water can wash the grease from wheel bearings, causing rusting and premature
failure, and may also enter the hybrid transmission case, reducing the gear oil’s
lubricating qualities.■
When you drive through water
If driving through water, such as when crossing shallow streams, first check the
depth of the water and the bottom of the riverbed for firmness. Drive slowly and
avoid deep water.■
Inspection after off-road driving ●
Sand and mud that has accumulated around brake discs may affect braking effi-
ciency and may damage brake system components.●
Always perform a maintenance inspection after each day of off-road driving that
has taken you through rough terrain, sand, mud, or water. For scheduled mainte-
nance information, refer to the “Warra nty and Services Guide/Owner’s Manual
Supplement/Schedul ed Maintenance”.

Break-in schedule
If your vehicle is new or equipped with any new power train components (such as
an engine, transmission, differential or wheel bearing), Lexus recommends that you
do not tow a trailer until the vehicle has been driven for over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start tow-
ing. However, for the next 500 miles (800 km), drive the vehicle at a speed of less
than 50 mph (80 km/h) when towing a trailer, and avoid full throttle acceleration.■
Maintenance ●
If you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (See “Warranty and Services Guide”, “Owner's Manual
Supplement” or “Scheduled Maintenance”.)●
Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.■
If trailer sway occurs
One or more factors (crosswinds, passing vehicles, rough roads, etc.) can adversely
affect handling of your vehicle and trailer, causing instability. ●
If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer sway ing by turning the steering wheel.
• Begin releasing the accelerator peda l immediately but very gradually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle and
trailer should stabilize. ●
After the trailer swaying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer.
Make sure the load has not shifted.
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle.
Make sure the vehicle is not ov erloaded after occupants get in.
If you cannot find any problems, the speed at which trailer swaying occurred is
beyond the limit of your particular vehicle-trailer combination.
Drive at a lower speed to prevent instability. Remember that swaying of the towing
vehicle-trailer increases as speed increases.

Repair and replacement
It is recommended that genuine Lexus parts be used for repair to ensure perfor-
mance of each system. If non-Lexus parts are used in replacement or if a repair
shop other than a Lexus dealer performs repairs, confirm the warranty coverage.To ensure safe and economical drivin g, day-to-day care and regular main-
tenance are essential. It is the owne r’s responsibility to perform regular
checks. Lexus recommends the following maintenance:
■ General maintenance
General maintenance should be performed on a daily basis. This
can be done by yourself or by a Lexus dealer.
■ Scheduled maintenance
Scheduled maintenance should be performed at specified intervals
according to the maintenance schedule. For details about maintenance items and schedules, refer to the “War-
ranty and Service Guide”, “Owner’s Manual Supplement” or “Scheduled
Maintenance”.
■ Do-it-yourself maintenance
You can perform some maintenance procedures yourself.
Please be aware that do-it-your self maintenance may affect war-
ranty coverage. The use of Lexus Repair Manuals is recommended.
For details about warranty coverage, refer to the separate “Owner’s
Guide”, “Warranty and Service Guide”, “Owner’s Manual Supplement”
or “Warranty Booklet”.
