DRIVING TIPS
466
NOTICE
If driving through water, such as when crossingshallow streams, first check the depth of the waterand the bottom of the river bed for firmness. Driveslowly and avoid deep water.
Take all necessary safety measures to ensure thatwater damage to the engine or other componentsdoes not occur.
Water entering the engine air intake will cause severe
engine damage.
Water can wash the grease from wheel bearings,causing rusting and premature failure, and may alsoenter the differentials, transmission and transfercase, reducing the gear oil's lubricating qualities.
Sand and mud that has accumulated in brake drumsand around brake discs may affect braking ef ficiency
and may damage brake system components.
Always perform a maintenance inspection after each day of off±road driving that has taken you throughrough terrain, sand, mud, or water. For scheduledmaintenance information, refer to the ªOwner'sManual Supplement/Scheduled Maintenanceº.

DRIVING TIPS
478
Tires
Ensure that your vehicle's tires are properly inflated. Adjust
the tire inflation pressure to the recommended cold tire
inflation pressure indicated below.
Tire inflation pressure: 220 kPa (2.2 kgf/cm
2 or bar, 32 psi)
 The trailer tires should be inflated to the pressure
recommended by the trailer manufacturer in respect to the
total trailer weight.
Trailer lights
Your vehicle is equipped with a wire harness stored in the rear
end underbody. Use either of them to connect and operate the
trailer lights. However, the trailer lights must comply with
federal, state/provincial and local regulations. See your local
recreational vehicle dealer or rental agency for the correct type
of wiring and relays for your trailer. Check for correct operation
of the turn signals and stop lights each time you hitch up. Direct
splicing may damage your vehicle's electrical system and
cause a malfunction of your lights.
Break±in schedule
Lexus recommends that you do not tow a trailer with a new
vehicle or a vehicle with any new power train component
(engine, transmission, differential, wheel bearing, etc.) for the
first 800 km (500 miles) of driving.
Maintenance
 If you tow a trailer, your vehicle will require more frequent
maintenance due to the additional load. For this
information, please refer to the scheduled maintenance
information in the ªOwner's Manual Supplement/Scheduled
Maintenanceº.
 Retighten all fixing bolts of the towing ball and bracket after
approximately 1000 km (600 miles) of trailer driving.
