Coolant type selection
Use of improper coolants may damage your engine cooling
system.
Only use “Toyota Super Long Life Coolant” or similar high
quality ethylene glycol based non−silicate, non −amine,
non− nitrite, and non −borate coolant with long −life hybrid
organic acid technology. (Coolant with long −life hybrid organic
acid technology is a combination of low phosphates and
organic acids.)
For the U.S.A.—“Toyota Super Long Life Coolant” is a mixture
of 50% coolant and 50% deionized water. This coolant
provides protection down to about –35 C (–31F).
For Canada—“Toyota Super Long Life Coolant” is a mixture of
55% coolant and 45% deionized water. This coolant provides
protection down to about –42 C (–44F).
NOTICE
Do not use plain water alone.
Lexus recommends “Toyota Super Long Life Coolant”, which
has been tested to ensure that it will not cause corrosion nor
result in malfunction of your engine coolant system with proper
usage. “Toyota Super Long Life Coolant” is formulated with
long−life hybrid organic acid technology and has been
specifically designed to avoid engine cooling system
malfunction on Lexus vehicles.
Please contact your Lexus dealer for further details.
CHECKING THE RADIATOR AND CONDENSER
If either of the above parts are extremely dirty or you are not
sure of their condition, take your vehicle to a Lexus dealer.
CAUTION
To prevent burning yourself, be careful not to touch the
radiator or condenser when the engine is hot.
NOTICE
To prevent damage to the radiator and condenser, do
not perform the work by yourself.

CHECKING POWER STEERINGFLUID
63X002a
Check the fluid level on the dipstick. If necessary, add
automatic transmission fluid DEXRONII or III .
If the vehicle has been driven around 80 km/h (50 mph) for 20
minutes (a little more in frigid temperatures), the fluid is hot
(60 C − 80C or 140F − 175F). You may also check the level
when the fluid is cold (about room temperature, 10 C − 30C
or 50F − 85F) if the engine has not been run for about five
hours.
63X003a
 1 If hot O.K. 2If hot add 3If cold O.K.
4If cold add
Clean all dirt off the reservoir and look at the fluid level. If the
fluid is cold, the level should be in the “COLD” range. Similarly,
if it is hot, the fluid level should be in the “HOT” range. If th\
e
level is at the low side of the appropriate range, add automatic
transmission fluid DEXRON
II or III to bring the level within
the range.
To remove the reservoir cap, turn it counterclockwise and lift
up. To reinstall it, turn it clockwise. After replacing the reservoir
cap, visually check the steering box case, vane pump and hose
connections for leaks or damage.
CAUTION
The reservoir may be hot so be careful not to burn
yourself.

NOTICE
Avoid overfilling, or the power steering could be
damaged.
 When adding the power steering fluid, avoid spilling
it. The generator under the power steering reservoir
could be damaged if fluid is spilled on it.
CHECKING SUSPENSION FLUID
AHC
63X007c
 1“MAX” line 2“MIN” line
Under the unloaded condition, check the Suspension
Fluid AHC in the following way.
1. Start the engine and put the vehicle height in the “LO” (Low)
mode and then “N” (Normal) mode.
2. Turn off the ignition switch about 30 seconds after the “N”
(Normal) mode indicator light comes on.
3. Make sure the fluid level is between “MAX” and “MIN”.
If the fluid level is lower than “MIN”, have suspension fluid AHC
filled by your Lexus dealer.

CHASSIS

NOTICE
Only use the Suspension fluid AHC for the active height
control suspension. If you fill other fluids such as brake
fluid, power steering fluid, engine oil, etc., the active
height control suspension could be damaged.
