wheel lexus LS400 1994 Gauges, Meters and Service Reminder Indicators / 1994 LS400: IN CASE OF AN EMERGENCY

IN CASE OF AN EMERGENCY
153 CAUTION:
When the engine is running, keep hands and clothing
away from the moving fan and engine drive belt.
4. If the engine drive belt is broken or loose, or the coolant is
leaking, stop the engine immediately. Call a Lexus dealer for
assistance.
5. If the engine drive belt is O.K. and there are no obvious
leaks, you may help the engine cool down more quickly by
running it at about 1500 rpm for a few minutes with the
accelerator pedal lightly depressed.
6. Check the coolant reservoir. If it is dry, add water to the
reservoir while the engine is running. Fill it about half full.
CAUTION:
Do not attempt to remove the reservoir cap when the
engine and radiator are hot. Serious injury could result
from scalding hot fluid and steam blown out under
pressure.
7. After the engine coolant temperature has cooled to normal,
again check the coolant level in the reservoir. If necessary,
bring it up to half full again. Serious coolant loss indicates a
leak in the system. You should have it checked as soon as
possible by your Lexus dealer.
IF YOU HAVE A FLAT TIRE
1. Reduce your speed gradually, keeping a straight line. Move
cautiously off the road to a safe place − well away from the
traffic. Avoid stopping on the center divider of a highway. Park
on a level spot with firm ground.
2. Stop the engine and turn on your emergency flashers.
3. Firmly set the parking brake and put the transmission in “P”.
4. Have everyone get out of the vehicle on the side away from
traffic.
5. Read the following instructions thoroughly.
CAUTION:
When jacking up the vehicle, observe the following to
reduce the possibility of personal injury:

Follow jacking instructions.

Use a jack only for lifting your vehicle during wheel
changing.

Never get beneath the vehicle when supported by a
jack.

Do not start or run the engine while your vehicle is
supported by a jack.

Spare tire
cover
Bolt
To remove the spare tire;
1. Remove the spare tire cover.
2. Loosen the bolt and remove it.
When storing the spare tire, place it with the inner side of the
wheel facing up. Then bolt the tire in place and install the spare
tire cover to prevent the tire from flying forward during a
collision or sudden braking.
Flat tire
Wheel block
3. Block the wheel diagonally opposite the flat tire to keep
the vehicle from rolling when it is jacked up.
When blocking the wheel, place the wheel block in front of the
front wheels or behind the rear wheels.
Paper for protecting
surface
4. Remove the wheel ornament.

IN CASE OF AN EMERGENCY
156Pry off the wheel ornament, using the screwdriver as shown.
To avoid personal injury, do not attempt to pull off the ornament
by hand.
5. Loosen all the wheel nuts.
Always loosen the wheel nuts before raising the vehicle.
The nuts turn counterclockwise to loosen. To get maximum
leverage, fit the wrench to the nut so that the handle is on the
right side, as shown above. Grab the wrench near the end of
the handle and pull up on the handle. Be careful that the
wrench does not slip off the nut.
Do not remove the nuts yet − just unscrew them about one-half
turn.
6. Position the jack at the jack points as shown.
Make sure the jack is positioned on a level and solid surface.
7. After making sure no one is in the vehicle, raise it high
enough so that the spare tire can be installed.

IN CASE OF AN EMERGENCY
157 Allow for the fact that you need more ground clearance when
putting on the spare tire than when removing the flat tire.
To raise the vehicle, insert the jack handle into the jack (it is a
loose fit) and turn it clockwise. As the jack touches the vehicle
and begins to lift, double-check that it is properly positioned.
CAUTION:
Never get under the vehicle when it is supported by the
jack alone.
8. Remove the wheel nuts and change tires.
Lift the flat tire straight off and put it aside.
Before putting on the wheel, remove any corrosion on the
mounting surfaces with a wire brush or such. Installation of
wheels without good metal-to-metal contact at the mounting
surface can cause wheel nuts to loosen and eventually cause
a wheel to come off while driving.
9. Reinstall all the wheel nuts finger tight.

IN CASE OF AN EMERGENCY
158Align the holes in the wheel with the bolts. Then lift up the wheel
and get at least the top bolt started through its hole. Wiggle the
tire and press it back over the other bolts.
Reinstall the wheel nuts and tighten them as much as you can
by hand. Press the tire back and see if you can tighten them
more.
Tighten
Tightening torque:
103 N.m (10.5 kgf.m, 76 ft.lb)
10. Lower the vehicle completely and tighten the wheel
nuts.
Turn the jack handle counterclockwise to lower the vehicle.
Use only the wheel nut wrench to tighten the nuts. Do not use
other tools or any additional leverage other than your hands,
such as a hammer, pipe or your foot. Make sure the wrench is
securely engaged over the nut.
Tighten each nut a little at a time in the order shown. Repeat
the process until all the nuts are tight.CAUTION:
As soon as possible after changing wheels, have the
wheel nuts tightened by torque wrench at 103 N
.m (10.5
kgf.m, 76 ft.lb).
11. Reinstall the wheel ornament.
Put the wheel ornament into position and then tap it firmly with
the side or heel of your hand to snap it into place.
12. After changing the wheel, check the air pressure of the
replaced tire. Restow all the tools, jack and flat tire
securely.
If the pressure is low, drive slowly to the nearest service station
and fill to the correct pressure.
Do not forget to reinstall the tire inflation valve cap as dirt and
moisture could get into the valve core and possibly cause air
leakage. If the cap is missing, have a new one put on as soon
as possible.
This is the same procedure for changing or rotating your tires.

IN CASE OF AN EMERGENCY
159 CAUTION:
Before driving, make sure all the tools, jack and flat tire are
securely in place in their storage location to reduce the
possibility of personal injury during a collision or sudden
braking.
IF YOUR VEHICLE NEEDS
TO BE TOWED
If towing is necessary, we recommend you have it done by
your Lexus dealer or a commercial tow truck service.
Proper equipment will help ensure that your vehicle is not
damaged while being towed. Commercial operators are
generally aware of the state / provincial and local laws
pertaining to towing.
Your vehicle can be damaged if it is towed incorrectly. Although
most operators know the correct procedure, it is possible to
make a mistake. To avoid damage to your vehicle, make sure
the following few precautions are observed. If necessary, show
this page to the tow truck driver.
TOWING PRECAUTIONS:
Use a safety chain system for all towing, and abide by the
state / provincial and local laws. The wheels and axle on the
ground must be in good condition. If they are damaged, use a
towing dolly.
For vehicles equipped with the height control system, turn the
height control ON / OFF switch to OFF before towing the
vehicle. See page 133.1. Using flat bed truck
Lexus recommends this as the best method for your vehicle..

IN CASE OF AN EMERGENCY
161 2. Towing with wheel lift type truck

From front
Use a towing dolly under the rear wheels.
NOTICE:
Never tow a vehicle with an automatic transmission from
the front with rear wheels on the ground, as this may
cause serious damage to the transmission.
From rear
Place the ignition key in the “ACC” position.
NOTICE:
Do not tow with the key removed or in the “LOCK”
position, as the steering lock mechanism is not strong
enough to hold the front wheels straight.

IN CASE OF AN EMERGENCY
1623. Towing with a sling type truck

From front
Follow the instructions for towing from front in “2. Towing with
wheel lift type truck”.

From rear
NOTICE:
Do not tow with sling type truck. This may cause body
damage.
Emergency towing
Emergency towing eyeletsEmergency towing eyelets
If towing service is not available in an emergency, your
vehicle may be temporarily trailed by a cable secured to
one of the eyelets under the front or rear of the vehicle.
A driver must be in the vehicle to steer it and operate the
brakes. Towing in this manner may be done only on
hard-surfaced roads for a short distance and at low speeds.
Also, the wheels, axles, drive train, steering and brakes must
all be in good condition.
Before towing, release the parking brake and put the
transmission in “N”. The key must be in “ACC” (engine off) or
“ON” (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.
