MAINTENANCE
347 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.
Parking brake
Check that the pedal has the proper travel and that, on a safe
incline, your vehicle is held securely with only the parking brake
applied.
Automatic transmission Parkº mechanism
On a safe incline, check that your vehicle is held securely with
the selector lever in Pº position and all brakes released.
Vehicle exterior
Items listed below should be performed from time to time,
unless otherwise specified.
Wheel nuts
When checking the tires, make sure to check the nuts for
looseness. Tighten them if necessary.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.
Tire inflation pressure
Check the tire inflation pressure with a gauge every
two weeks, or at least once a month and adjust as
shown on the tire and loading information label. See
page 389 for additional information.
Tire surface
Check the tires carefully for cuts, damage or
excessive wear. See page 402 for additional
information.
Tire rotation
Rotate the tires according to the maintenance
schedule. (For scheduled maintenance information,
please refer to the Owner's Manual
Supplement/Scheduled Maintenanceº.) See page 401
for additional information.

DOES YOUR VEHICLE NEED
REPAIRING?
Be on the alert for changes in performance and sounds, and
visual tip-offs that indicate service is needed. Some important
clues are:
Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A fluid leak under the vehicle (However, water dripping from
the air conditioning after use is normal.)
Change in exhaust sound (This may indicate a dangerous
carbon monoxide leak. Drive with the windows open and
have the exhaust system checked immediately.)
Flat-looking tires, excessive tire squeal when cornering,
uneven tire wear
Vehicle pulls to one side when driving straight on a level
road
Strange noises related to suspension movement
Loss of brake effectiveness, spongy feeling brake pedal,
pedal almost touches floors, vehicle pulls to one side when
braking
Engine coolant temperature continually higher than normalIf you notice any of these clues, take your vehicle to your Lexus
dealer as soon as possible. It probably needs adjustment or
repair.
CAUTION
Do not continue driving with the vehicle unchecked. It
could result in serious vehicle damage and possibly
personal injury.

PARTS AND TOOLS
Here is a list of parts and tools you will need to perform
do-it-yourself maintenance. Remember all Lexus parts are
designed in metric sizes, so your tools must be metric.
Checking the engine oil level
Parts (if level is low):
Toyota Genuine Motor Oilº or equivalent
See page 374 for details about engine oil selection.
Tools:
Rag or paper towel
Funnel (only for adding oil)
Checking the engine coolant level
Parts (if level is low):
Toyota Super Long Life Coolantº or similar high quality
ethylene glycol based non-silicate, non-amine, non-nitrite,
and non-borate coolant with long-life hybrid organic acid
technology
Toyota Super Long Life Coolantº is pre-mixed with 50%
coolant and 50% deionized water. This coolant provides
protection down to about -35C (-31F).
Tools:
Funnel (only for adding coolant)
Checking brake fluid
Parts (if level is low):
FMVSS No. 116 DOT 3 or SAE J1703 brake fluid
Tools:
Funnel (only for adding fluid)
Checking power steering fluid
Parts (if level is low):
Automatic transmission fluid DEXRON
II or III
Tools:
Rag or paper towel
Funnel (only for adding fluid)
Checking battery condition
Tools:
Warm water
Baking soda
Grease
Conventional wrench (for terminal clamp bolts)
Checking and replacing the blade type fuses

CHECKING BRAKE FLUID
To check the fluid level, simply look at the see-through
reservoir. The level should be between the MAXº and
MINº 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 MAXº 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.
