CAUTION
If the tire pressure warning light comes on, be sure to
observe the following precautions. Failure to do so
could cause loss of vehicle control and result in death
or serious injury.
Vehicles with runflat tires:
 Decelerate to the lowest appropriate speed as soon
as possible. Do not drive over 90 km/h (55 mph).
 Check and adjust the tire inflation pressure
immediately.
 If the tire pressure warning light comes on even after
tire inflation pressure adjustment, it is probable that
you have a flat tire. Have the tire replaced by the
nearest Lexus dealer.
 Avoid abrupt maneuvering and braking. If the vehicle
tires deteriorate, you could lose control of the
steering wheel or the brakes.
Vehicles with standard tires:
 Stop your vehicle in a safe place as soon as possible.
Adjust the tire inflation pressure immediately.
 If the tire pressure warning light comes on even after
tire inflation pressure adjustment, it is probable that
you have a flat tire. Check the tires. If the tire is flat,
change to the spare tire and have the flat tire repaired
by the nearest Lexus dealer.
 Avoid abrupt maneuvering and braking. If the vehicle
tires deteriorate, you could lose control of the
steering wheel or the brakes.

IN CASE OF AN EMERGENCY
477
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 use liquid sealants for a flat tire as tire
pressure sensors will be damaged.
 Do not continue driving with a deflated tire.
Driving even a short distance can damage a tire
beyond repair.
 When the tires must be repaired and replaced,
have them repaired and replaced by your Lexus
dealer or an authorized tire dealer. The tire
pressure warning valves and transmitters will
be affected by the installation or removal of
tires.
 When the tires must be replaced, replace the
grommets for tire pressure warning vales and
transmitters as well.
Compact spare tire
G40025
The compact spare tire is designed for temporary
emergency use only.
The compact spare tire is identified by the distinctive
wording “TEMPORARY USE ONLY” molded into the
side wall of the tire.
To keep the compact spare tire noticeable, do not hide
the wheel by a wheel cover or such.
The compact spare tire saves space in your luggage
compartment, and its lighter weight helps to improve fuel
economy and permits easier installation in case of a flat
tire.

IN CASE OF AN EMERGENCY

G40024
To remove the spare tire:
1Remove the luggage tray.
2Loosen 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 and
install the luggage tool box to prevent the tire from flying
forward during a collision or sudden braking.
G40007
4. Block the wheel diagonally opposite the flat tire to
keep the vehicle from rolling when it is jacked up.
When blocking the wheel, place a wheel block in front of
one of the front wheels or behind one of the rear wheels.

7. 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.
CAUTION
Never get under the vehicle when the vehicle is
supported by the jack alone.
G40011
8. Remove the wheel nuts and remove the flat tire.
Lift the flat tire straight off and put it aside.

Chain installation
Install the chains on the rear tires as tightly as possible.
Do not use tire chains on the front tires. Retighten chains
after driving 0.5 1.0 km (1/4 1/2 mile).
When installing chains on your tires, carefully follow the
instructions of the chain manufacturer.
CAUTION
Do not exceed 50 km/h (30 mph) or the chain
manufacturer’s recommended speed limit,
whichever is lower.
 Drive carefully avoiding bumps, holes, and sharp
turns, which may cause the vehicle to bounce.
 Avoid sharp turns or lockedwheel braking, as use of
chains may adversely affect vehicle handling.
 When driving with chains installed, be sure to drive
carefully. Slow down before entering curves to avoid
losing control of the vehicle. Otherwise an accident
may occur.
NOTICE
When the snow tires must be repaired or replaced,
have them repaired or replaced by Lexus dealer or
authorized tire dealer. The tire pressure warning
valves and transmitters will be affected by the
installation or removal of snow tires.
 When the snow tires must be replaced, replace the
grommets for tire pressure warning valves and
transmitters as well.
 Do not attempt to use a tire chain on the compact
spare tire, as it may result in damage to the vehicle as
well as the tire.
If the chains are installed, the tire pressure warning
system may not operate properly. See “Tire pressure
warning system” on page 440.
