WARNING
■
Replacing a flat tire
●
Do not touch the disc wheels or the area around the brakes immediately after the
vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the brakes will
be extremely hot. Touching these areas with hands, feet or other body parts while
changing a tire, etc. may result in burns.
●
Failure to follow these precautions could cause the wheel nuts to loosen and the tire
to fall off, resulting in death or serious injury.
• Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened, leading to
bolt or disc wheel damage. In addition, the oil or grease can cause the wheel nuts
to loosen and the wheel may fall off, causing a serious accident. Remove any oil or
grease from the wheel bolts or wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 76 ft•lbf (103 N•m,
10.5 kgf•m) as soon as possible after changing wheels.
• Do not attach a heavily damaged wheel ornament, as it may fly off the wheel while
the vehicle is moving.
• When installing a tire, only use wheel nuts that have been specifically designed for
that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads or bolt holes
of the wheel, have the vehicle inspected by your Lexus dealer.

ses
Remove any dirt or foreign matter
from the wheel contact surface.
If foreign matter is on the wheel contact
surface, the wheel nuts may loosen
while the vehicle is in motion, causing
the tire to come off.
Install the spare tire and loosely tighten each wheel nut by hand by approxi-
mately the same amount.
When replacing an aluminum wheel
with a steel wheel, tighten the wheel
nuts until the tapered portion comes
into loose contact with the disc
wheel seat.
When replacing an aluminum wheel
with an aluminum wheel, turn the
wheel nuts until the washers come
into contact with the disc wheel.
Lower the vehicle.

■
The spare tire
●
RC350/RC300:
The spare tire is identified by the label “TEMPORARY USE ONLY” on the tire sidewall.
●
Use the spare tire temporarily, and only in an emergency.
●
Make sure to check the tire inflation pressure of the spare tire. (
■
When using the spare tire
As the spare tire is not equipped with a tire pressure warning valve and transmitter, low
inflation pressure of the spare tire will not be indicated by the tire pressure warning sys-
tem. Also, if you replace the spare tire after the tire pressure warning light comes on, the
light remains on.
■
When the spare tire is equipped
The vehicle becomes lower when driving with the spare tire compared to when driving
with standard tires.
■
If you have a flat rear tire on a road covered with snow or ice (vehicles with front and
rear tires of the same size except for vehicles with LDH and 19-inch tires)
Install the spare tire on one of the front wheels of the vehicle. Perform the following steps
and fit tire chains to the rear tires:
Replace a front tire with the spare tire.
Replace the flat rear tire with the tire removed from the front of the vehicle.
Fit tire chains to the rear tires.

cle. Do not use your spare tire on another vehicle.
●
Do not use more than one spare tires simultaneously.
●
Replace the spare tire with a standard tire as soon as possible.

affect the drive-train components:
• AWD system (if equipped)
■
Speed limit when using the spare tire
Do not drive at speeds in excess of 50 mph (80 km/h) when a spare tire is installed on

The spare tire is not designed for driving at high speeds. Failure to observe this precau-
tion may lead to an accident causing death or serious injury.
■
After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in their storage
location to reduce the possibility of personal injury during a collision or sudden brak-
ing.

7-2. Steps to take in an emergency
RC F_U
If you have a flat tire (vehicles with an emergency
tire puncture repair kit)
Your vehicle is not equipped with a spare tire, but instead is equipped with an
emergency tire puncture repair kit.
A puncture caused by a nail or screw passing through the tire tread can be
repaired temporarily with the emergency tire puncture repair kit.
WARNING
■
If you have a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the wheel beyond
repair. Driving with a flat tire may cause a circumferential groove on the side wall. In
such a case, the tire may explode when using the emergency tire puncture repair kit,
resulting in death or serious injury.

●
Set the parking brake.
●
Shift the shift lever to P.
●
Stop the engine.

• To avoid sealant leakage, move the vehicle until the area of the puncture, if
known, is positioned at the top of the tire.

When the tire is damaged due to driving without sufficient air pressure
●
When the tire lost air pressure due to a crack or damage in the tire sidewall
●
When the tire is visibly separated from the wheel
●
When the cut or damage to the tread is 0.16 in. (4 mm) long or more
●
When the wheel is damaged
