parking brake Lexus GX470 2004 Audio System / LEXUS 2004 GX470 FROM NOV. 2003 THROUGH DEC. 2003 PROD. (OM60A74U) Owner's Guide

DRIVING TIPS
453 When restarting out after parking on a slope:
1. With the transmission in Pº position, start the engine. Be
sure to keep the brake pedal depressed.
2. Shift into the 3º, 2º, Lº or Rº position.
3. Release the parking brake and brake pedal and slowly pull
or back away from the wheel blocks. Stop and apply your
brakes.
4. Have someone retrieve the blocks.
CAUTION
Do not exceed 72 km/h (45 mph) or the posted towing
speed limit, whichever is lower. Because instability
(swaying) of a towing vehicle-trailer combination
usually increases as the speed increases, exceeding
72 km/h (45 mph) may cause loss of control.
Slow down and downshift before descending steep
or long downhill grades. Do not make sudden
downshifts.
Avoid holding the brake pedal down too long or too
frequently. This could cause the brakes to overheat
and result in reduced braking efficiency.
HOW TO SAVE FUEL AND MAKE
YOUR VEHICLE LAST LONGER
Improving fuel economy is easy Ð just take it easy. It will help
make your vehicle last longer, too. Here are some specific tips
on how to save money on both fuel and repairs:
Keep your tires inflated at the correct pressure. Check
the pressure every two weeks, or at least once a month.
Underinflation causes tire wear and wastes fuel.
Do not carry unneeded weight in your vehicle. Excess
weight puts a heavier load on the engine, causing greater
fuel consumption.
Avoid lengthy warm-up idling. Once the engine is
running smoothly, begin driving Ð but gently. Remember,
however, that on cold winter days this may take a little
longer.
Always keep the automatic transmission selector lever
in the Dº position when engine braking is not required.
Driving with the overdrive off will reduce the fuel economy.
(For details, see Automatic transmissionº on page 376.)
Accelerate slowly and smoothly. Avoid jackrabbit starts.
Avoid long engine idling. If you have a long wait and you
are not in traffic, it is better to turn off the engine and start
again later.
Avoid engine over-revving. Use a gear position suitable
for the road on which you are traveling.

IN CASE OF AN EMERGENCY
467
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.

IN CASE OF AN EMERGENCY
469
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 Pº. Block the wheel
diagonally opposite to the one being changed
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 the jack only for lifting your vehicle
during wheel changing.
Do not raise the vehicle with someone in the
vehicle.
When raising the vehicle, do not place any
objects on top of or underneath the jack.
Raise the vehicle only high enough to remove
and change the tire.

IN CASE OF AN EMERGENCY
490
CAUTION
Use extreme caution when towing the vehicle. Avoid
sudden starts or erratic driving maneuvers which would
place excessive stress on the emergency towing eyelet
and towing cable or chain. The eyelet and towing cable
or chain may break and cause serious injury or damage.
NOTICE
Use only a cable or chain specifically intended for use
in towing vehicles. Securely fasten the cable or chain
to the towing eyelet provided.
Before towing, check that the center differential is unlocked.
(The indicator light must be off with the ignition on.) Release
the parking brake and put the transmission in Nº. The ignition
key must be in ACCº (engine off) or ONº (engine running).
CAUTION
If the engine is not running, the power assist for the
brakes and steering will not work so steering and
braking will be much harder than usual.
Emergency towing hook precautions:
Before emergency towing, check that the eyelet is not
broken or damaged and that the installation bolts are not
loose.
Fasten the towing cable or chain securely to the hook.
Do not jerk the eyelet. Apply steady and even force.
To avoid damaging the eyelet, do not pull from the side or at
a vertical angle. Always pull straight ahead.

IF YOU CANNOT SHIFT AUTOMATIC
TRANSMISSION SELECTOR LEVER
If you cannot shift the selector lever out of Pº position to
other positions even though the brake pedal is depressed,
use the shift lock override button as follows:
1Turn the ignition key to LOCKº. Make sure the parking
brake is applied.
2Pry up the cover with a flat-bladed screwdriver or
equivalent.
3Push down the shift lock override button. You can shift out
of Pº position only while pushing the button.
4Shift into Nº position.
Insert the cover. Start the engine. For your safety, keep
the brake pedal depressed.
Be sure to have the system checked by your Lexus dealer as
soon as possible.

MAINTENANCE
517 Brakes

and all brakes released.
Vehicle exterior
Items listed below should be performed from time to time,
unless otherwise specified.

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 557 for additional
information.
Tire surface
Check the tires carefully for cuts, damage or
excessive wear. See page 571 for additional
information.
Wheel nuts
