LUGGAGE STOWAGE PRECAUTIONS
When stowing luggage or cargo in the vehicle, observe the following:
Put luggage or cargo in the trunk when at all possible. Be sure all items are
secured in place.
 Be careful to keep the vehicle level. Placing the weight as far forward\
as
possible helps maintain vehicle balance.
 For better fuel economy, do not carry unnecessary weight.
CAUTION
Do not place anything on the filler panel behind the rear
seatback. Such items may be thrown about and possibly
injure people in the vehicle during sudden braking or an
accident.
 Do not drive with objects left on top of the instrument
panel. They may interfere with the driver's field of view.
Or they may move during sharp vehicle acceleration or
turning, and impair the driver's control of the vehicle. In
an accident they may injure the vehicle occupants.
NOTICE
Do not load the vehicle beyond the vehicle capacity weight specified on
the tire pressure label.

STARTING AND DRIVING
148
BRAKE SYSTEM
The tandem master cylinder brake system is a hydraulic system with two
separate sub±systems. If either sub±system should fail, the other will still
work. However, the pedal will be harder to press, and your stopping distance
will be longer. Also, the brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a single brake system.
Have your brakes fixed immediately.
Brake booster
The brake booster uses engine vacuum to power±assist the brakes. If the
engine should quit while you are driving, you can bring the vehicle to a stop
with normal pedal pressure. There is enough reserve vacuum for one or t\
wo
stops but no more!
CAUTION
Do not pump the brake pedal if the engine stalls. Each push
on the pedal uses up your vacuum reserve.
 Even if the power assist is completely lost, the brakes will
still work. But you will have to push the pedal hard ± much
harder than normal. And your braking distance will be
longer.
Anti±lock brake system
The anti±lock brake system is designed to automatically help prevent
lock±up of the wheels during a sudden brake or braking on slippery road
surfaces. This assists in providing directional stability and steering
performance of the vehicle under these circumstances.
The anti±lock brake system becomes operative after the vehicle has
accelerated to a speed in excess of approximately 10 km/h (6 mph). It stops
operating when the vehicle decelerates to a speed below approximately 5
km/h (3 mph).
You may hear a sound in the engine compartment for a few seconds when the
engine is started or just after the vehicle is started. This means that the
anti±lock brake system is in the self±check mode, and does not indicate a
malfunction.
Effective way to press the ABS brake pedal: When the anti±lock brake
system function is in action, you may feel the brake pedal pulsating and hear
a noise. In this situation, to let the anti±lock brake system work f\
or you, just
hold the brake pedal down more firmly. Do not pump the brake. This will
result in reduced braking performance.
The brake pedal pulsation caused by the anti±lock brake system may indic\
ate
hazardous road surface conditions. Although the anti±lock brake system
assists in providing vehicle control, it is still important to drive with all due
care, because the anti±lock brake system cannot overcome the laws of physic\
s
that act on your vehicle:
 Braking capability is dependent on tire friction with the road surface.

DRIVING TIPS
156
Brakes and safety chains
Lexus recommends trailers with brakes that conform to any
applicable federal and state/provincial regulations.
 A safety chain must always be used between the towing vehicle and the
trailer. Leave sufficient slack in the chain for turns. The chain should
cross under the trailer tongue to prevent the tongue from dropping to
the ground in case it becomes damaged or separated. For correct
safety chain procedures, follow the hitch or trailer manufacturer's
recommendations.
CAUTION
 If the total trailer weight exceeds 450 kg (1000 lb.), trailer
brakes are required.
 Never tap into your vehicle's hydraulic system as it will
lower its braking effectiveness.
 Never tow a trailer without using a safety chain securely
attached to both the trailer and the vehicle. If damage
occurs to the coupling unit or hitch ball, there is possible
danger of the trailer wandering over into another lane.
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 e ach 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 ºOwner'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.

DRIVING TIPS159
HOW TO SAVE FUEL AND MAKE YOURVEHICLE LAST LONGER
Getting more kilometer/mileage from a liter/gallon of fuel is easy ± just ta\
ke
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 warm±up 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 traf fic,
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. Stop±and±go 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.

IN CASE OF AN EMERGENCY
172
40E012
9. Lower the vehicle completely and tighten the wheel nuts.
Turn the jack handle counterclockwise to lower the vehicle.
Use only the wheel nut wrench to tighten the nuts. Do not use other tools \
or
any additional leverage other than your hands, such as a hammer, pipe or your
foot. Make sure the wrench is securely engaged over the nut.
Tighten each nut a little at a time in the order shown. Repeat the process unti\
l
all the nuts are tight.
CAUTION
 When lowering the vehicle, make sure all portions of your
body and all other persons around will not be injured as the
vehicle is lowered to the ground.
 As soon as possible after changing wheels, have the wheel
nuts tightened by torque wrench at 103 N´m (10.5 kgf´m, 76
ft´lbf.).
10. After changing the wheel, check the air pressure of the replaced tire.
Stow all the tools, jack and flat tire securely.
If the pressure of the replaced tire is low, drive slowly to the nearest service
station and fill to the correct pressure.
Do not forget to reinstall the tire valve cap as dirt and moisture could get into
the valve core and possible cause air leakage. If the cap is missing, put a new
one on as soon as possible.
This is the same procedure for changing or rotating your tires.
CAUTION
Before driving, make sure all the tools, jack and flat tire are
securely in place in their storage location to reduce the
possibility of personal injury during a collision or sudden
braking.

CHECKING TIRE PRESSURE
63E004±1
The recommended cold tire pressures, tire size and the vehicle capacity
weight are given on the label.
You should check the tire pressures every two weeks, or at least once a mon\
th.
And don't forget the spare! The air pressure for the spare tire should be 220
kPa (2.2 kgf/cm
2 or bar, 32 psi). Incorrect tire pressure can reduce tire life and
make your vehicle less safe to drive. Low tire pressure results in excessive wear, poor handling, reduced fuel
economy,
and the possibility of blowouts from overheated tires. Also, low tire
pressure can cause poor sealing of the tire bead. If the tire pressure is
excessively low, there is the possibility of wheel deformation and/or tire
separation. So keep your tire pressures at the proper level. If a tire needs
frequent refilling, have it checked by your Lexus dealer.
High tire pressure produces a harsh ride, handling problems, excessive wear
at the center of the tire tread, and a greater possibility of tire damage \
from road
hazards.
The following instructions for checking tire pressure should be observed:
 The pressure should be checked only when the tires are cold. If your
vehicle has been parked for at least 3 hours and has not been driven for
more than 1.5 km or 1 mile since, you will get an accurate cold tire pressure
reading.
 Always use a tire pressure gauge. The appearance of the tire can be
misleading. Besides, tire pressures that are even just a few pounds off can
degrade handling and ride.
 Do not bleed or reduce tire pressure after driving. It is normal for the
tire pressure to be higher after driving.
 Never exceed the vehicle capacity weight. The passengers and luggage
weight should be located so that the vehicle is balanced.
 Be sure to reinstall the tire valve caps. Without the valve caps, dirt or
moisture could get into the valve core and cause air leakage. If the ca\
ps
have been lost, have new ones put on as soon as possible.

ROTATING TIRES
63E005±1
To equalize tire wear and help extend tire life, Lexus recommends that
you rotate your tires approximately every 12000 km (7500 miles).
However, the most appropriate timing for tire rotation may vary
according to your driving habits and road surface conditions.
The wheel assemblies must be rotated as illustrated above.
When rotating tires, check for uneven wear and damage. Abnormal wear is\
usually caused by incorrect tire pressure, improper wheel alignment, out\
±of
balance wheels, or severe braking.
Before storing radial, snow or studded tires, mark the direction of rotation an\
d
be sure to install them in the same direction when using them again. Tire\
s
should be stored in a cool dry place.
CHECKING AND REPLACING TIRES
When to replace your tires
63E006

1 New tread 2Tread wear indicator 3Worn tread
Replace the tires when the tread wear indicators show. The location of
the tread wear indicators is shown by the marks such as ºTWIº or º
Dº
marks molded on the sidewall of each tire.
The tires on your Lexus have built±in tread wear indicators to help you \
know
when the tires need replacement. When the tread depth wears to 1.6 mm (0.06
in.) or less, the indicators will appear. If you can see the indicators in two or
more adjacent grooves, the tire should be replaced.
The effectiveness of snow tires is lost if the tread wears down below 4 mm
(0.16 in.).
