When trouble arises
tire chains to the front tires:
1Replace a rear tire with the com-
pact spare tire.
2 Replace the flat front tire with the
tire removed from the rear of the
vehicle.
3 Fit tire chains to the front tires.
WARNING
■When using the compact
spare tire
●Remember that the compact
spare tire provided is specifi-
cally designed for use with your
vehicle. Do not use your com-
pact spare tire on another vehi-
cle.
●Do not use more than one com-
pact spare tire simultaneously.
●Replace the compact spare tire
with a standard tire as soon as
possible.
●Avoid sudden acceleration,
abrupt steering, sudden brak-
ing and shifting operations that
cause sudden engine braking.
■When the compact spare tire
is attached
The vehicle speed may not be
correctly detecte d, and the follow-
ing systems may not operate cor-
rectly:
• ABS & Brake assist
• VSC/Trailer Sway Control
•TRAC
• Dynamic radar cruise control with full-speed range
• PCS (Pre-Collision System)
•EPS
• LTA (Lane Tracing Assist)
• Tire pressure warning system
• AHB (Automatic High Beam)
• AFS (Adaptive Front-lighting System) (if equipped)
• BSM (Blind Spot Monitor)
• Rear view monitor system (if equipped)
• Panoramic view monitor (if equipped)
• Toyota parking assist monitor (if equipped)
• Intuitive parking assist (if equipped)
• PKSB (Parking Support Brake) (if equipped)
• Navigation system (if equipped)
Also, not only c an the following
system not be utilized fully, but it
may actually negatively affect the
drive-train components:
• E-Four (Electronic On-Demand
AWD system)
■Speed limit when using the
compact spare tire
Do not drive at speeds in excess
of 50 mph (80 km /h) when a com-
pact spare tire is installed on the
vehicle.
The compact spare tire is not
designed for driving at high
speeds. Failure to observe this
precaution may lead to an acci-
dent causing death or serious
injury.
■After using the tools and jack
Before driving, ma ke 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
braking.

5348-2. Steps to take in an emergency
One of the following may be the
cause of the problem:
The AC charging cable may
be attached to the vehicle.
( P.123)
 The electronic key may not be
functioning properly.
( P.537)
 There may not be sufficient
fuel in the vehicle’s tank.
Refuel the vehicle. ( P.306)
 There may be a malfunction
in the immobilizer system.
( P.72)
 There may be a malfunction
in the steering lock system.
 The hybrid system may be
malfunctioning due to an elec-
trical problem such as elec-
tronic key battery depletion or
a blown fuse. However,
depending on the type of mal-
NOTICE
■Be careful when driving over
bumps with the compact
spare tire installed on the
vehicle
The vehicle height may become
lower when driving with the com-
pact spare tire compared to when
driving with standard tires. Be
careful when driving over uneven
road surfaces.
■Driving with tire chains and
the compact spare tire
Do not fit tire chains to the com-
pact spare tire.
Tire chains may damage the vehi-
cle body and adversely affect driv-
ing performance.
■When replacing the tires
When removing or fitting the
wheels, tires or the tire pressure
warning valve and transmitter,
contact your Toyota dealer as the
tire pressure warning valve and
transmitter may be damaged if not
handled correctly.
If the hybrid system
will not start
Reasons for the hybrid sys-
tem not starting vary
depending on the situation.
Check the following and
perform the appropriate
procedure:
The hybrid system will not
start even though the cor-
rect starting procedure is
being followed ( P.279)

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 d oes not have a tube and air is directly put in to the tire. A
tube type tire has a tube inside t he tire and the tube maintains the air pres-
sure.

Summer tires or all season tires ( P.469)
An all season tire has “M+S” on the sidewal l. A tire not marked “M+S” is a
summer tire.

■Temperature A, B, C
The temperature grades are A
(the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure.
Grade C corresponds to a level of performance which all passenger
car tires must meet under the Fed-
eral Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher
levels of performance on the labo-
ratory test wheel than the minimum
required by law.
Warning: The temperature grades
of a tire assume tha
t it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can cause
heat buildup and possible tire fail-
ure.
