Automatic headlight leveling system
(Vehicles with discharge headlight only)
12E044
As the headlight beam level is always maintained
automatically at the proper level in all loading conditions,
your headlights do not dazzle other road users.
If this system fails, the warning light in the instrument
cluster comes on. If this occurs, have your vehicle
checked by Lexus dealer.HEADLIGHT DIMMER ANDTURN SIGNAL SWITCH

36For signaling
turns, move the lever up or down in the
conventional manner.
The ignition key must be in the ªONº position.
The turn signal is self±cancelling after a turn, but after a
lane change, you may have to cancel it by hand. You can
also signal a lane change by moving the turn signal lever
partway and holding it there.
If the green light in the instrument cluster flashes faster
than normal, it indicates that the front or rear turn signal
bulb has burned out. If this indicator light does not come
on, the fuse or the indicator light itself has probably
failed.
FOG LIGHT SWITCH
12E005±1
To turn on the fog lights, turn the switch to the ªONº
position. The fog lights come on only when the
headlights are on low beam.WINDSHIELD WIPER AND WASHER SWITCH

To turn on the emergency flashers, push the switch.
All the turn signal lights will flash. The emergency
flashers
will work with the engine running or off and with
or without the ignition key.
Turn on the emergency flashers to warn other drivers if
you must stop your vehicle where it might be a traffic
hazard.
Always pull your vehicle as far off the road as possible.
The turn signal light switch will not work when the
emergency flashers are in operation.
NOTICE
To prevent the battery from being discharged, do not leave the switch on longer than necessarywhen the engine is not running.

DRIVING TIPS
327
Tires
Ensure that your vehicle's tires are properly inflated.
Adjust the tire pressure to the recommended cold tire
pressure indicated below:
Tire pressure, kPa (kgf/cm
2 or bar, psi)
Front 220 (2.2, 32)
Rear 220 (2.2, 32)
The trailer tires should be inflated to the pressure
recommended by the trailer manufacturer in respect
to the total trailer weight.
Trailer lights
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/ Maintenance Scheduleº.
Retighten all fixing bolts of the towing ball and bracket
after approximately 1000 km (600 miles) of trailer
driving.
Pre±towing safety check
Check that your vehicle remains level when a loaded
or unloaded trailer is hitched. Do not drive if the
vehicle has an abnormal nose±up or nose±down
condition, and check for improper tongue load,
overload, worn suspension or other possible causes.
Make sure the trailer cargo is securely loaded so that
it cannot shift.
Check that your rear view mirrors conform to any
federal, state/provincial or local regulation. If they do
not, install required rear view mirrors appropriate for
towing purposes.
