DRIVING TIPS
473
After driving through tall grass, mud, rock, sand,
rivers, etc., check that there is no grass, bush, paper,
rags, stone, sand, etc. adhering or trapped on the
underbody. Clear off any such matter from the
underbody. If the vehicle is used with these materials
trapped or adhering to the underbody, a breakdown
or fire could occur.
In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing
a seat belt. Therefore, the driver and all passengers
should fasten their seat belts whenever the vehicle is
moving.
When driving off road or in rugged terrain, do not
drive at excessive speeds, jump, make sharp turns,
strike objects, etc. This may cause loss of control or
vehicle rollover causing death or serious injury. You
are also risking expensive damage to your vehicle’s
suspension and chassis.NOTICE
If driving through water, such as when crossing
shallow streams, first check the depth of the water
and the bottom of the river bed for firmness. Drive
slowly and avoid deep water.
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 can wash the grease from wheel bearings,
causing rusting and premature failure, and may also
enter the differentials, transmission and transfer
case, reducing the gear oil’s lubricating qualities.
Sand and mud that has accumulated in brake drums
and 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 through
rough terrain, sand, mud, or water. For scheduled
maintenance information, refer to the “Owner’s
Manual Supplement / Scheduled Maintenance”.

Trailer lights
Socket for trailer lights
Your vehicle is equipped with a wire harness stored in the rear
end underbody. Models with tow hitch receiver are fitted with
a socket for trailer lights under the rear bumper. 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 “Owner’s Manual Supplement /
Scheduled Maintenance”.
Retighten all fixing bolts of the towing ball and bracket after
approximately 1000 km (600 miles) of trailer driving.
Connecting a trailer (models with
electronically modulated air suspension)
Stop your vehicle and a trailer in line and perform the following:
1. Put the electronically modulated air suspension in the “LO”
mode. Turn the ignition switch off or push the height control
switch to turn off the electronically modulated air suspension.
2. Connect a trailer.
3. Turn the ignition switch on or push the height control switch
to turn on the electronically modulated air suspension. Select
the “N” (normal) mode with the height select switch.
