1999 LEXUS SC300 spare tire

IN CASE OF AN EMERGENCY
284

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 put an object on or
under the jack.

Raise the vehicle only high enough to remove and
change the tire.
NOTICE
Do not continue driving with a deflated tire. Driving even
a short distance can damage a tire beyond repair.
Changing procedure
1. Get the tool, jack and spare tire.
To prepare yourself for an emergency, you should familiarize
yourself with the use of the jack and each tool, and their
storage locations.

IN CASE OF AN EMERGENCY
286
Loosen the bolt and remove it.
When storing the spare tire, place it with the outer side of the
wheel facing up. Then bolt the tire in place to prevent the tire
from flying forward during a collision or sudden braking.

5. After making sure no one is in the vehicle, raise it high
enough so that the spare tire can be installed.
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.

CHASSIS
364The recommended cold tire pressures, tire size and the
vehicle capacity weight are given on the label.
You should check the tire pressures every two weeks, or at
least
once a month. And don't forget the spare! The pressure
for the spare tire should be same with that for the standard tire.
(See page 356 or 358.) Incorrect tire pressure can reduce tire
life and make your vehicle less safe to drive.
Low tire pressure results in excessive wear, poor handling,
reduced fuel economy, and the possibility of blowouts from
overheated tires. Also, low tire pressure can cause poor
sealing of the tire bead. If the tire pressure is excessively low,
there is the possibility of wheel deformation and/or tire
separation. So keep your tire pressures at the proper level. If
a tire needs frequent refilling, have it checked by your Lexus
dealer. High tire pressure produces a harsh ride, handling problems,
excessive wear at the center of the tire tread, and a greater
possibility of tire damage from road hazards.
The following instructions for checking tire pressure should
be observed:

The pressure should be checked only when the tires are
cold. If your vehicle has been parked for at least 3 hours
and has not been driven for more than 1.5 km or 1 mile
since, you will get an accurate cold tire pressure reading.
 Always use a tire pr essure gauge. The appearance of the
tire can be misleading. Besides, tire pressures that are even
just a few pounds off can degrade handling and ride.
 Do not bleed or reduce tire pressure after driving. It is
normal for the tire pressure to be higher after driving.
 Never exceed the vehicle capacity weight. The
passengers and luggage weight should be located so that
the vehicle is balanced.
 Be sure to reinstall the tire valve caps. Without the valve
caps, dirt or moisture could get into the valve core and
cause air leakage. If the caps have been lost, have new
ones put on as soon as possible.

Replace the tires when the tread wear indicators show.
The location of the tread wear indicators is shown by the
ºTWIº or º
Dº marks molded on the sidewall of each tire.
The tires on your Lexus have built±in tread wear indicators to
help you know when the tires need replacement. When the
tread depth wears to 1.6 mm (0.06 in.) or less, the indicators
will appear. If you can see the indicators in two or more
adjacent grooves, the tire should be replaced.
The effectiveness of snow tires is lost if the tread wears
down below 4 mm (0.16 in.).
If you have tire damage such as cuts, splits, cracks deep
enough to expose the fabric, or bulges indicating internal
damage, the tire should be replaced. If a tire often goes flat or cannot be properly repaired due to
the size or location of a cut or other damage, it should be
replaced. If you are not sure, consult with your Lexus dealer.
If an air loss occurs while driving, do not continue driving
with a deflated tire. Driving even a short distance can damage
a tire beyond repair.
Any tires which are over 6 years old must be checked by
a qualified technician even if damage is not obvious.
Tires deteriorate with age even if they have never or seldom
been used.
This also applies to the spare tire and tires stored for future
use.
