2022 LEXUS RC300 ABS

3007-2. Steps to take in an emergency
RC350/RC300 Owner's Manual
WARNING
■If both the ABS and the brake system
warning lights remain on
Stop your vehicle in a safe place immedi-
ately and contact your Lexus dealer. The
vehicle will become extremely unstable
during braking, and the ABS system may
fail, which could cause an accident
resulting in death or serious injury.
■When the electric power steering
system warning light comes on
The steering wheel may become
extremely heavy.
When steering wheel operations are
heavier than usual, grip the steering
wheel firmly and operate it using more
force than usual.
■If the tire pressure warning light
comes on
Be sure to observe the following precau-
tions. Failure to do so could cause a loss
of vehicle control and result in death or
serious injury.
●Stop your vehicle in a safe place as
soon as possible. Adjust the tire infla-
tion 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 a tire is flat,
change it with the spare tire and have
the flat tire repaired by the nearest
Lexus dealer.
●Avoid abrupt maneuvering and brak-
ing. If the vehicle tires deteriorate, you
could lose control of the steering
wheel or the brakes.
■If a blowout or sudden air leakage
should occur
The tire pressure warning system may
not activate immediately.
■Maintenance of the tires
Each tire, including the spare (if pro-
vided), should be checked monthly when
cold and inflated to the inflation pressure
recommended by th e vehicle manufac-
turer on the vehicle pl acard or tire infla-
tion pressure label (tire and load
information label). (If your vehicle has
tires of a different size than the size indi-
cated on the vehicle placard or tire infla-
tion pressure labe l [tire and load
information label], yo u should determine
the proper tire inflation pressure for
those tires.)
As an added safety fe ature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS-tire pressure
warning system) that illuminates a low
tire pressure telltale (tire pressure warn-
ing light) when one or more of your tires
is significantly under-inflated. Accord-
ingly, when the low ti re pressure telltale
(tire pressure warnin g light) illuminates,
you should stop and check your tires as
soon as possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire
to overheat and can lead to tire failure.
Under-inflation also reduces fuel effi-
ciency and tire tread life, and may affect
the vehicle’s handling and stopping abil-
ity.
Please note that the TPMS (tire pressure
warning system) is not a substitute for
proper tire maintena nce, and it is the
driver’s responsibility to maintain correct
tire pressure, even if under-inflation has
not reached the level to trigger illumina-
tion of the TPMS low tire pressure telltale
(tire pressure warning light).

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
sudden braking.
