2004 Lexus GX470 check transmission fluid

DRIVING TIPS
415 Use a washer fluid containing an antifreeze solution.
This product is available at your Lexus dealer and most auto
parts stores. Follow the manufacturer's directions for how
much to mix with water.
NOTICE
Do not use engine antifreeze or any other substitute
because it may damage your vehicle's paint.
Do not use your parking brake when there is a possibility
it could freeze.
When parking, put the transmission into Pº and block the front
wheels. Do not use the parking brake, or snow or water
accumulated in and around the parking brake mechanism may
freeze the parking brake, making it hard to release.Keep ice and snow from accumulating under the fenders.
Ice and snow built up under your fenders can make steering
difficult. During bad winter driving, stop and check under the
fenders occasionally.
Depending on where you are driving, we recommend you
carry some emergency equipment.
Some of the things you might put in the vehicle are tire chains,
window scraper, bag of sand or salt, flares, small shovel,
jumper cables, etc.

IN CASE OF AN EMERGENCY
443
IF YOUR VEHICLE OVERHEATS
If your engine coolant temperature gauge indicates
overheating, if you experience a loss of power, or if you
hear a loud knocking or pinging noise, the engine has
probably overheated.
When the engine overheats
Pull safely off the road, stop the vehicle and turn on your
emergency flashers. Put the transmission in Pº and apply the
parking brake.
A: If steam is coming from your engine:
Turn off the engine. Leave the hood closed until there is no sign
of steam or coolant. Your engine could have been seriously
damaged already. Call your Lexus dealer for assistance.
CAUTION
To help avoid personal injury, keep the hood closed until
there is no steam. Escaping steam or coolant is sign of
very high pressure.
B: If no steam is coming from your engine:
Leave the engine running and turn off the air conditioning.
Check the following.
Is the cooling fan operating?
Is the coolant in the acceptable range?
Is the engine drive belt O.K.?
CAUTION
When the engine is running, keep hands and clothing
away from the moving fan and engine drive belt.
Do not attempt to remove the radiator cap when the
engine and radiator are hot. Serious injury could
result from scalding hot fluid and steam blown out
under pressure.
If the cooling fan is not operating or the coolant is not in the
acceptable range, turn off the engine and call your Lexus
dealer.
If both conditions are O.K., after the engine coolant
temperature has cooled to normal, continue driving your
vehicle.
If the engine coolant temperature does not cool down, or your
vehicle overheats again, have it checked as soon as possible
by your Lexus dealer.

MAINTENANCE
491 Brakes
At a safe place, check that the brakes do not pull to one side
when applied.
Parking brake
Check that the lever 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
Check the lock release button of the selector lever for proper
and smooth operation. 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.
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 side doors and back door, 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 pressure with a gauge every two weeks,
or at least once a month and adjust as shown on the
tire pressure label. See page 532 for additional
information.
Tire surface
Check the tires carefully for cuts, damage or
excessive wear. See page 545 for additional
information.
Wheel nuts
When checking the tires, make sure to check the nuts
for looseness. Tighten them if necessary.
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 544
for additional information.

NOTICE

Remember that battery and ignition cables carry high
currents or voltages. Be careful of accidentally
causing a short circuit.

Before closing the engine hood, check to see that you
have not forgotten any tools, rags, etc.

Do not drive with the air cleaner removed, or
excessive engine wear could result. Also backfiring
could cause a fire in the engine compartment.

Do not overfill automatic transmission fluid and
power steering fluid, or the transmission and power
steering could be damaged.

Be careful not to scratch the glass surface with the
wiper frame.

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 518 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 POWER STEERING
FLUID
The power steering fluid reservoir is located under the
right side engine compartment cover. Before checking
the power steering fluid, remove the cover. (For details,
see Removing the engine compart coversº on page 500.)
Check the fluid level, simply look at the see-through
reservoir. If necessary, add automatic transmission fluid
DEXRON
II 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
(60C - 80C or 140F - 175F). You may also check the level
when the fluid is cold (about room temperature, 10C - 30C
or 50F - 85F) if the engine has not been run for about five
hours.

1If cold O.K.2If cold add3If hot O.K.
4If hot add
Clean all dirt off the reservoir and look at the fluid level. If the
fluid is cold, the level should be in the COLDº range. Similarly,
if it is hot, the fluid level should be in the HOTº range. If the
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.
