CAUTION
When jacking, be sure to observe the following to
reduce the possibility of personal injury:
Follow jacking instructions.
 Do not put any part of your body under the vehicle
supported by the jack. Personal injury may occur.
 Do not start or run the engine while your vehicle is
supported by the jack.
 Stop the vehicle on a level firm ground, firmly set the
parking brake and put the transmission in ªPº. Block
the wheels on the opposite side of the jack up point
if necessary.
 Make sure to set the jack properly in the jack point.
Raising the vehicle with jack improperly positioned
will damage the vehicle or may allow the vehicle to fall
off the jack and cause personal injury.
 Never get under the vehicle when the vehicle is
supported by the jack alone; use vehicle support
stands.
 Do not raise the vehicle with someone in the vehicle.
 When raising the vehicle, do not put an object on or
under the jack.

CHECKING BRAKE FLUID

Vehicles equipped with traction control system
To check the fluid level, simply look at the
see±through
reservoir. The level should be between
the ªMAXº and ªMINº lines on the tank.
It is normal for the brake fluid level to go down slightly as
the brake pads wear. So be sure to keep the reservoir
filled.
If the reservoir needs frequent refilling, it may indicate a
serious mechanical 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 cap by hand. Add
brake fluid up to the ªMAXº 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 hands or eyes and damage painted
surfaces. If fluid gets in your hands or eyes, flush them
with clean water immediately. If you still feel
uncomfortable with your hands or eyes, go to the
doctor.

REPLACING WHEELS
When to replace your wheels
If you have wheel damage such as bending, cracks
or heavy corrosion, the wheel should be replaced.
If you fail to replace damaged wheels, a tire may slip off
a wheel or cause loss of handling control.
Replacement with used wheels is not recommended as
they may have been subjected to rough treatment or
high mileage and could fail without warning. Also, bent
wheels which have been straightened may have hidden
structural damage and therefore should not be used.
Never use an inner tube in a leaking wheel which is
designed for a tubeless tire.
Wheel selection
When replacing wheels, care should be taken to
ensure that they are equivalent to those removed in
load capacity, diameter, rim width, and offset.
Correct replacement wheels are available at your Lexus
dealer.
A wheel of a different size or type may adversely affect
handling, wheel and bearing life, brake cooling,
speedometer/odometer calibration, stopping ability,
headlight aim, bumper height, vehicle ground clearance,
and tire or snow chain clearance to the body and
chassis.
ALUMINUM WHEEL PRECAUTIONS
 When installing aluminum wheels, check that the
wheel nuts are tight after driving your vehicle the first
1600 km (1000 miles).
 If you have rotated, repaired, or changed your tires,
check that the wheel nuts are still tight after driving
1600 km (1000 miles).
 When using tire chains, be careful not to damage the
aluminum wheels.
 Use only the Lexus wheel nuts and wrench designed
for your aluminum wheels.
 When balancing your wheels, use only Lexus
balance weights or equivalent and a plastic or rubber
hammer.
 As with any wheel, periodically check your aluminum
wheels for damage. If damaged, replace
immediately.
