Use fluids that are appropriate to
the prevailing outside temperatures.
•Engine oil
• Engine coolant
•Washer fluid
Have a service technician inspect
the condition of the battery.
 Have the vehicle fitted with four
snow tires.
Ensure that all tires are the specified size
and the same brand.
Perform the following according to the
driving conditions:
Do not try to forcibly open a window
or move a wiper that is frozen. Pour
warm water over the frozen area to
melt the ice. Wipe away the water
immediately to prevent it from
freezing.
 To ensure proper operation of the
climate control system fan, remove
any snow that has accumulated on
the air inlet vents in front of the
windshield.
 Check for and remove any excess
ice or snow that may have accumu-
lated on the exterior lights, vehicle’s
roof, chassis, around the tires or on
the brakes.
 Remove any snow or mud from the
bottom of your shoes before getting
in the vehicle.
Accelerate the vehicle slowly, keep a
safe distance between you and the
vehicle ahead, and drive at a reduced
speed suitable to road conditions.
Winter driving tips
Carry out the necessary prepara-
tions and inspections before driving
the vehicle in winter. Always drive
the vehicle in a manner appropriate
to the prevailing weather condi-
tions.
Preparation for winter
WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in a loss of
vehicle control and cause death or seri-
ous injury.
●Use tires of the specified size.
●Maintain the recommended level of air
pressure.
●Do not drive in excess of 75 mph (120
km/h), regardless of the type of snow
tires being used.
●Use snow tires on all, not just some
wheels.
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow
tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attach-
ment of snow tires affects the operation
of the tire pressure warning valves and
transmitters.

RC F Owner's Manual
■Brake caliper coating
●When using detergent, use neutral deter-
gent. Do not use hard brushes or abra-
sive cleaners, as they will damage the
paint.
●Do not use detergent on the brake cali-
pers when they are hot.
●Wash detergent off immediately after
use.
■Brake pads and calipers
Rust may form if the vehicle is parked with
wet brake pads or disc rotors, causing them
to stick. Before parking the vehicle after it is
washed, drive slowly and apply the brakes
several times to dry the parts.
■Bumpers
Do not scrub with abrasive cleaners.
■Side windows water- repellent coating
●The following precautions can extend the
effectiveness of the water-repellent coat-
ing.
• Remove any dirt, etc. from the side win- dows regularly.
• Do not allow dirt and dust to accumulate
on the windows for a long period.
Clean the windows with a soft, damp cloth
as soon as possible.
• Do not use wax or glass cleaners that contain abrasives when cleaning the win-
dows.
• Do not use any metallic objects to remove condensation build up.
●When the water-repellent performance
has become insufficient, the coating can
be repaired. Contact your Lexus dealer.
■Plated portions
If dirt cannot be removed, clean the parts as
follows:
●Use a soft cloth dampened with an approximately 5% solution of neutral
detergent and water to clean the dirt off.
●Wipe the surface with a dry, soft cloth to
remove any remaining moisture.
●To remove oily deposits, use alcohol wet
wipes or a similar product.
WARNING
■When washing the vehicle
Do not apply water to the inside of the
engine compartment. Doing so may
cause the electrical components, etc. to
catch fire.

When trouble arises
WARNING
●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.
Vehicles with an emergency tire punc-
ture repair kit
●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,
repair the flat tire by using emergency
tire puncture repair kit.
●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 the vehicle manufac-
turer on the vehicle placard 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 label [tire and load
information label], you should determine
the proper tire infl ation 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).
Your vehicle has also been equipped with
a TPMS (tire pressure warning system)
malfunction indicator to indicate when
the system is not operating properly. The
TPMS (tire pressure warning system)
malfunction indicator is combined with
the low tire pressure telltale (tire pres-
sure warning light) . When the system
detects a malfunction, the telltale will
flash for approximately one minute and
then remain continuously illuminated.
This sequence will continue upon subse-
quent vehicle start-ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may
not be able to detect or signal low tire
pressure as intended.

When trouble arises
step 22.
21 Turn the compressor switch on to
inflate the tire until the recom-
mended tire inflation pressure is
reached. Drive for about 3 miles (5
km) and then perform step 19.
22 Attach the air release cap to the
end of the hose.
If the air release cap is not attached, the
sealant may leak and the vehicle may get
dirty.
23Store the bottle in the trunk while it
is connected to the compressor.
24 Taking precautions to avoid sud-
den braking, sudd en acceleration
and sharp turns, drive carefully at
under 50 mph (80 km/h) to your
Lexus dealer that is less than 62
miles (100 km) away for tire repair
or replacement.
■After a tire is repaired with the emer-
gency tire puncture repair kit
●The tire pressure warning valve and
transmitter should be replaced.
●Even if the tire inflat ion pressure is at the
recommended level, the tire pressure
warning light may come on/flash.
■If the tire is inflated to more than the
recommended level
1 Disconnect the hose from the valve.
2 Install the air release cap to the end of
the hose and push the protrusion on the air release cap into the valve to let some
air out.
3 Disconnect the hose from the valve,
remove the air release cap from the
hose and then reconnect the hose.
4 Turn the compressor sw itch on and wait
for several seconds, then turn it off.
Check that the air pressure indicator
shows the recommended level.
(  P.345)
If the air pressure is lower than the rec-
ommended level, tu rn the compressor
switch on again and repeat the inflation
procedure until the recommended
pressure is reached.
WARNING
■When fixing the flat tire
Observe the following precautions.
Failure to do so may result in death or
serious injury.
●Stop your vehicle in a safe and flat
area.
●Do not touch the wheels or the area
around the brakes immediately after
the vehicle has been driven.
After the vehicle has been driven, the
wheels and the area around the brakes
may be extremely hot. Touching these
areas with hands, feet or other body
parts may result in burns.
●Connect the valve and hose securely
with the tire installed on the vehicle.
• If the hose is not properly connected to the valve, air leakage may occur or
sealant may be sprayed out.

When trouble arises
1Remove 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.
2 Install the spare tire and loosely
tighten each wheel nut by hand by
approximately the same amount.
When replacing an aluminum wheel with
an aluminum wheel, turn the wheel nuts
until the washers come into contact
with the disc wheel .
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 of f, 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 of f, 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.
NOTICE
■Precaution for CCB (Carbon
Ceramic Brake) discs (if equipped)
Do not subject the carbon ceramic brake
disc to strong impact.
It the carbon ceramic brake disc has
been subjected to a strong impact, even
if there is no obvious damage, have the
