HEADLIGHT DIMMER AND TURN
SIGNAL SWITCH
12L003
For high beam, push the lever forward. Pull it back for low
beam. For the headlight flasher, pull it further back.
A blue light in the instrument cluster indicates high beam or
headlight flasher is on.
The headlight flasher works even when the headlight switch is off.
12L004
For signaling turns, move the lever up or down in the
conventional manner.
The ignition key must be in the ”ON” position.
The turn signal is selfcancelling 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.

CAUTION
To avoid serious personal injury, you must do the following.
Always make sure the head, hands and other parts of the
body of all occupants are kept completely inside the vehicle
before you close the power windows. If someone’s neck,
head or hands gets caught in a closing window, it could
result in a serious injury. When anyone closes the power
windows, be sure that they operate the windows safely.
When small children are in the vehicle, never let them use
the power window switches without supervision. Use the
window lock switch to prevent them from making
unexpected use of the switches.
Never leave small children alone in the vehicle, especially
with the ignition key still inserted. They could use the
power window switches and get trapped in a window.
Unattended children can become involved in serious
accidents.
EMERGENCY FLASHER SWITCH
12L0121
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 necessary when the engine is not running.

DRIVING TIPS

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.
Breakin 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/ Maintenance Schedule”.
Retighten all fixing bolts of the towing ball and bracket after
approximately 1000 km (600 miles) of trailer driving.
Pretowing 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
noseup or nosedown 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.

HOW TO SAVE FUEL AND MAKE
YOUR VEHICLE LAST LONGER
Getting more kilometer/mileage from a liter/gallon of fuel is easy
just take it easy. It will help make your vehicle last longer, too. Here
are some specific tips on how to save money on both fuel and repairs:
Keep your tires inflated at the correct pressure. Check the
pressure every two weeks, or at least once a month.
Underinflation causes tire wear and wastes fuel.
Do not carry unneeded weight in your vehicle. Excess weight
puts a heavier load on the engine, causing greater fuel
consumption.
Avoid lengthy warmup idling. Once the engine is running
smoothly, begin driving but gently. Remember, however, that
on cold winter days this may take a little longer.
Accelerate slowly and smoothly. Avoid jackrabbit starts.
Avoid long engine idling. If you have a long wait and you are
not in traffic, it is better to turn off the engine and start again later.
Avoid engine overrevving. Use a gear position suitable for the
road on which you are traveling.
Avoid continuous speeding up and slowing down.
Stopandgo driving wastes fuel.Avoid unnecessary stopping and braking. Maintain a steady
pace. Try to time the traffic signals so you only need to stop as
little as possible or take advantage of through streets to avoid
traffic lights. Keep a proper distance from other vehicles to avoid
sudden braking. This will also reduce wear on your brakes.
Avoid heavy traffic or traffic jams whenever possible.
Do not rest your foot on the brake pedal. This causes needless
wear, overheating and poor fuel economy.
Maintain a moderate speed on highways. The faster you drive,
the greater the fuel consumption. By reducing your speed, you
will cut down on fuel consumption.
Keep the front wheels in proper alignment. Avoid hitting the
curb and slow down on rough roads. Improper alignment not only
causes faster tire wear but also puts an extra load on the engine,
which, in turn, wastes fuel.
Keep the bottom of your vehicle free from mud, etc. This not
only lessens weight but also helps prevent corrosion.
Keep your vehicle tunedup and in top shape. A dirty air
cleaner, improper valve clearance, dirty plugs, dirty oil and
grease, brakes not adjusted, etc. all lower engine performance and
contribute to poor fuel economy. For longer life of all parts and
lower operating costs, keep all maintenance work on schedule,
and if you often drive under severe conditions, see that your
vehicle receives more frequent maintenance. (For scheduled
maintenance information, please refer to the separate ”Owner’s
Manual Supplement/Maintenance Schedule”.)
CAUTION

MAINTENANCE
215 Tire rotation
Rotate the tires every 12000 km (7500 miles). See page 242 for
additional information.
Fluid leaks
Check underneath for leaking fuel, oil, water or other fluid after the
vehicle has been parked for a while. If you smell fuel fumes or notice
any leak, have the cause found and corrected immediately.
Doors and engine hood
Check that all doors, including trunk lid, operate smoothly and all
latches lock securely. Make sure the engine hood secondary latch
secures the hood when the primary latch is released.
Vehicle interior
Items listed below should be checked regularly, e.g. while
performing periodic services, cleaning the vehicle, etc.
Lights

and other lights are working. Check headlight aim.
Service reminder indicators and warning buzzers
Check that all service reminder indicators and warning buzzers
function properly.Steering wheel
Check that it has the specified freeplay. Be alert for changes in
steering condition, such as hard steering, excessive freeplay or
strange noise.
Seats
Check that all front seat controls such as seat adjusters, seatback
recliner, etc. operate smoothly. Check that the head restraints move
up and down smoothly and that the locks hold securely in any latched
position.
Seat belts
Check that the seat belt system such as buckles, retractors and
anchors operate properly and smoothly. Make sure the belt webbing
is not cut, frayed, worn or damaged.
Accelerator pedal
Check the pedal for smooth operation and uneven pedal effort or
catching.
Brake pedal
Check the pedal for smooth operation and the proper clearance and
freeplay. Check the brake booster function.
Brakes
At a safe place, check that the brakes do not pull to one side when
applied.
