BRAKE PAD WEAR LIMIT INDICATORS
31E016
The brake pad wear limit indicators on your disc brakes give a warning
noise when the brake pads are worn to the extent that replacement is
required.
If you hear a squealing or scraping noise while driving, have the brake \
pads
checked and replaced by your Lexus dealer as soon as possible. Expensive
rotor damage can result if the pads are not replaced when needed.
TYPES OF TIRES
Determine what kind of tires your vehicle is originally equipped with.
1. Summer tires
Summer tires are high±speed capability tires best suited to highway driving\
under dry conditions.
Since summer tires do not have the same traction performance as snow tires,
summer tires are inadequate for driving on snow±covered or icy roads. For
driving on snow±covered or icy roads, we recommend using snow tires. If
installing snow tires, be sure to replace all four tires.
2. All season tires
All season tires are designed to provide better traction in snow and to \
be
adequate for driving in most winter conditions, as well as for use all year
round.
All season tires, however, do not have adequate traction performance
compared with snow tires in heavy or loose snow. Also, all season tires fall
short in acceleration and handling performance compared with summer tires
in highway driving.
CAUTION
Do not mix summer and all season tires on your vehicle as
this can cause dangerous handling characteristics,
resulting in loss of control.
 Do not use tires other than the manufacturer's designated
tires, and never mix tires or wheels of the sizes different
from the originals.

JUMP STARTING PROCEDURE
1. If the booster battery is installed in another vehicle, make sure the vehi\
cles
are not touching. Turn off all unnecessary lights and accessories.
2. If required, remove all the vent plugs from the booster battery. Lay a cloth
over the open vents on the booster battery. (This helps reduce the explosion
hazard, personal injuries and burns.)
3. If the engine in the vehicle with the booster battery is not running, st\
art it
and let it run for about 5 minutes. During jump starting, run the engine a\
t about
2000 rpm with the accelerator pedal lightly depressed.
4. Locate
positive (+) and negative (±) terminals of each battery. Connect the
jumper cables in the exact order (
1
2 3 4) shown in the illustration.
1
Connect a positive (red) jumper cable clamp to the positive (+) terminal
of the discharged battery.
2Connect the clamp at the other end of the positive (red) cable to the
positive (+) terminal of the booster battery.
3Connect a negative (black) cable clamp to the negative (±) terminal of
the booster battery.
4Connect the clamp at the other end of the negative (black) cable to a
solid, stationary, unpainted metallic point (e.g. cylinder head) away
from the battery. Do not connect it to or near any part that moves when
the engine is cranked.
CAUTION
When making the connections, to avoid serious injury, do not
lean over the battery or accidentally let the jumper cables or
clamps touch anything except the correct battery terminals or
the ground.
5. Start your engine in the normal way. After starting, run it at about 2000 rpm
for several minutes with the accelerator pedal lightly depressed. 6. Carefully disconnect the cables in the exact reverse order: the negative
cable and then the positive cable.
7. Carefully dispose of the battery cover cloths which may now contain
sulfuric acid.
8. If removed, replace all the battery vent plugs.
If the cause of your battery discharging is not apparent (for example, lights left
on), you should have it checked.

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.

IF YOU LOSE YOUR KEYS OR LOCKYOURSELF OUT
Many Lexus dealers can make a new key if you can give them the key
number. Since your vehicle is equipped with the engine immobiliser
system, the dealer will also need your master key.
See the suggestion given in ºKeysº on page 7.
If your keys are locked in the vehicle and you cannot get a duplicate, m\
any
Lexus dealers can still open the door for you, using their special tools. If you
must break a window to get in, we suggest breaking the smallest side window
because it is the least expensive to replace. Be extremely cautious to avoid
cuts from the glass.
Even if you lose only one key, contact your Lexus dealer to make a new key.
If you lose all your master keys, you cannot make new keys; the whole syst\
em
must be replaced.

MAINTENANCE

MAINTENANCE REQUIREMENTS
Your Lexus vehicle has been designed to have fewer maintenance
requirements with longer service intervals to save both your time and money.
However, each regular maintenance as well as day±to±day care is more
important than ever before to ensure smooth, trouble±free, safe, and
economical driving.
It is the owner's responsibility to make sure the specified maintenance,
including general maintenance services, is performed. Note that both the new
vehicle and emission control system warranties specify that proper
maintenance and care must be performed. See the Owner's Guide, Owner's
Manual Supplement or Warranty Booklet for complete warranty information.
General maintenance
General maintenance items are those day±to±day care practices that are
important to your vehicle for proper operation. It is the owner's responsibility
to ensure that the general maintenance items are performed regularly.
These checks or inspections can be done either by yourself or your Lexus
dealer.
Scheduled maintenance
The scheduled maintenance items listed in the ºOwner's Manual
Supplement/Maintenance Scheduleº are those required to be serviced at
regular intervals. For details of your maintenance schedule, read the separate ºOwner's Manual
Supplement/Maintenance Scheduleº.
It is recommended that any replacement parts used for maintenance or
for the repair of the emission control system be Lexus supplied.
The owner may elect to use non±Lexus supplied parts for replacement
purposes without invalidating the emission control system warranty.
However, use of replacement parts which are not of equivalent quality
may impair the effectiveness of the emission control systems.
You may also elect to have maintenance, replacement, or repair of the
emission
control devices and system performed by any automotive r epair
establishment or individual without invalidating this warranty. See
Owner's Guide, Owner's Manual Supplement or Warranty Booklet for
complete warranty information.
Where to go for service?
Lexus technicians are well±trained specialists and are kept up to date wit\
h the
latest service information through technical bulletins, service tips, and
in±dealership training programs. They are well informed about the operation
of all the systems on your vehicle.
You can be confident that your Lexus dealer's service department performs
the best job to meet the maintenance requirements of your vehicle.

CHECKING BRAKE FLUID
63E001
To check the fluid level, simply look at the see±through reservoir. The
level should be between the ºMAXº and ºMINº lines on the tank.
It is normal for the brake fluid level to go down slightly as the brake pa\
ds wear.
So be sure to keep the reservoir filled.
If the reservoir needs frequent refilling, it may indicate a serious mec\
hanical
problem.
If the level is low, add FMVSS No.116 DOT 3 or SAE J1703 brake fluid
to the brake reservoir.
Remove and replace the reservoir cover by hand. Add brake fluid up to the
ºMAXº line.
Use only newly opened brake fluid. Once opened, brake fluid absorbs
moisture from the air, and excess moisture can cause a dangerous loss of
braking efficiency.
CAUTION
Take care when filling the reservoir because brake fluid can
harm your eyes and damage painted surfaces. If fluid gets in
your eyes, flush your eyes with clean water.
NOTICE
If you spill some of the fluid, be sure to wash it off with water to prevent
it from damaging the parts or paintwork.

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.).
