When trouble arises
■When the spare tire is equipped
The vehicle becomes lower when driving
with the spare tire compared to when driv-
ing with standard tires.
■If you have a flat rear tire on a road cov-
ered 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:
1 Replace a front tire with the spare tire.
2 Replace the flat rear tire with the tire
removed from the front of the vehicle.
3 Fit tire chains to the rear tires.
WARNING
■When using the spare tire
●Remember that the spare tire provided
is specifically desi gned for use with
your vehicle. Do not use your spare
tire on another vehicle.
●Do not use more than one spare tire
simultaneously.
●Replace the spare tire with a standard
tire as soon as possible.
●Avoid sudden acceleration, abrupt
steering, sudden braking and shifting
operations that cause sudden engine
braking.
■When the spare tire is attached
The vehicle speed may not be correctly
detected, and the following systems may
not operate correctly:
• ABS & Brake assist
•VSC
•TRAC
• Dynamic radar cruise control with full-speed range
•PCS
•EPS
• Adaptive Variable Suspension System (if equipped)
• LDA (Lane Departure Alert with steering control)
• VGRS (if equipped)
• LDH (Lexus Dynamic Handling sys- tem) (if equipped)
• DRS (Dynamic Rear Steering) (if equipped)
• VDIM (Vehicle Dynamics Integrated Management)
• Tire pressure warning system
•Lexus parking assist monitor
• Intuitive parking assist (if equipped)
• Navigation system (if equipped)
Also, not only can the following system
not be utilized fully, bu t it may even nega-
tively 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 vehicle.
The spare tire is not designed for driving
at high speeds. Failure to observe this
precaution may lead to an accident caus-
ing 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

Full-size tireTire size ( P.341)
DOT and Tire Identification Number (TIN) ( P.340)
Location of treadwear indicators ( P.263)
Tire ply composition and materials
Plies are layers of rubber-coa ted parallel cords. Cords are the strands which form the plies
in a tire.
Radial tires or bias-ply tires
A radial tire has “RADIAL” on the sidewall. A tire not marked “RADIAL” is a bias-ply tire.
TUBELESS or TUBE TYPE
A tubeless tire does not have a tube and air is directly put into the tire. A tube type tire has a
tube inside the tire and the tube maintains the air pressure.
Load limit at maximum cold tire inflation pressure ( P.343)
Maximum cold tire inflation pressure ( P.343)
This means the pressure to which a tire may be inflated.
Uniform tire quality grading
For details, see “Uniform Tire Quality Grading” that follows.
Summer tires or all season tires ( P.264)
An all season tire has “M+S” on the sidewall. A tire not marked “M+S” is a summer tire.
