At this time, vibration may occur. However, if you depress the
accelerator pedal more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle checked by your
Lexus dealer as soon as possible.
Even if the abnormality of the electronic throttle control system
is corrected during low speed driving, the system may not be
recovered until the engine is stopped and the ignition key is
turned to ªACCº or ªLOCKº position.
CAUTION
Be especially careful to prevent erroneous pedal
operation.
Emissions inspection and maintenance (I/M) programs
Your vehicle may not pass a state emission inspection if the
malfunction indicator lamp remains on. Contact your Lexus
dealer to check your vehicle's emission control system and
OBD (On±Board Diagnostics) system before taking your
vehicle for the inspection.
For details, see ªEmissions inspection and maintenance (I/M)
programsº on page 532.
(f) ªABSº Warning Light
The light comes on when the ignition key is turned to the ªONº
position. If the anti±lock brake system and the brake assist
system work properly, the light turns off after a few seconds.
Thereafter, if either of the systems malfunctions, the light
comes on again.
When the ªABSº warning light is on (and the brake system
warning light is off), the following systems do not operate, but
the brake system still operates conventionally.

Anti±lock brake system
 Brake assist system
 Active traction control system
 Vehicle stability control system
 Downhill assist control system
 Hill±start assist control
When the ªABSº warning light is on (and the brake system
warning light is off), the anti±lock brake system does not
operate, so that the wheels will lock up during a sudden braking
or braking on slippery road surfaces.

AIR CONDITIONING
257
The air conditioning filter is behind the glove box.
The air conditioning filter may clog after long use. The filter
may need to be replaced if the air flow of the air conditioner and
heater experiences extreme reductions in operating ef ficiency,
or if the windows begin to fog up easily.
To maintain the air conditioning efficiency, inspect and replace
the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, such
as inner city or desert areas, early replacement may be
required. (For scheduled maintenance information, please
refer to the ªOwner's Manual Supplement/Scheduled
Maintenanceº.)1. Open the glove box and unhook the cip as shown
above.
2. Push in each side of the glove box to disconnect the
claws.

STARTING AND DRIVING
395

If the engine becomes difficult to start or stalls
frequently, take your vehicle in for a check±up assoon as possible. Remember, your Lexus dealerknows your vehicle and its three±way catalyticconverter system best.
To ensure that the three±way catalytic converter andthe entire emission control system operate properly,your vehicle must receive the periodic inspectionsrequired by the Lexus Maintenance Schedule. For
scheduled maintenance information, refer to theªOwner's Manual Supplement/ScheduledMaintenanceº.

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.
