Before driving

■System maintenance
The vehicle has a maintenance-free type of engine immobilizer system.
■Conditions that may cause the system to malfunction
●If the grip portion of the key is in contact with a metallic object.
●If the key is in close proximity to or touching a key to the security system (key
with a built-in transponder chip) of another vehicle.
CAUTION
■Certifications for the engine immobilizer system
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
NOTICE

of the system cannot be guaranteed.

Do not use LDA in any of the following situations.
Otherwise, the system may not function correctly and could result in an accident.
●When driving with snow tires, tire ch ains, a spare tire, or similar equipment.
●When driving with non-standard part s or aftermarket equipment installed

preted as lane markers (such as guardrails, curbs, reflector posts, etc.).
●When there is snow in the wheel tracks of the road.

NOTICE
■To prevent the water damage
Take all necessary safety measures to ensure that water damage to the engine or
other components does not occur.
●Water entering the engine air intake will cause severe engine damage.
●Water entering the automatic transmission wi ll cause deterioration in shift quality,
locking up of your transmission accompanied by vibration, and ultimately dam-
age.
●Water can wash the grease from wheel bearings, causing rusting and premature
failure, and may also enter the differentials, transmission and transfer case, reduc-
ing 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 in brake drums and around brake discs may
affect braking efficiency 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 “Warrant y and Services Guide”, “Owner’s Manual
Supplement” or “Scheduled Maintenance”.

When driving
GX460_U.S.A. (OM60E69U)
■Break-in schedule
Lexus recommends that you do not use a new vehicle or a vehicle with any new
power train components (engine, transmission, differential, wheel bearings, etc.) to
tow a trailer for the first 500 miles (800 km) of driving.
■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.
CAUTION
■Trailer towing precautions
●Follow all the instructions described in this section. Failure to do so could cause
an accident resulting in death or serious injury.
●Exceeding the towing capacity, GVWR, GCWR and GAWR can cause an acci-
dent resulting in death or serious personal injuries.
