4-5. Using the driving support systems
WARNING
■Stopping distance when the ABS is operating may exceed that of normal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always main-
tain a safe distance from the vehicle in front of you, especially in the following situations:
●When driving on dirt, gravel or snow-
covered roads
●When driving with tire chains
●When driving over bumps in the road
●When driving over roads with potholes or uneven surfaces
■TRC/VSC may not operate effec-tively when
Directional control and power may not be achievable while driving on slippery
road surfaces, even if the TRC/VSC sys- tem is operating.
Drive the vehicle carefully in conditions where stability and power may be lost.
■Hill- start assist control does not operate effectively when
●Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on steep inclines and roads covered with ice.
●Unlike the parking brake, hill-start assist control is not intended to hold
the vehicle stationary for an extended period of time. Do not attempt to use hill-start assist control to hold the vehi-
cle on an incline, as doing so may lead to an accident.
■When the TRC/VSC/ABS is acti-vated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are the systems to help ensure vehicle stability and dr iving force, do not turn the TRC/VSC systems off unless
necessary.
■Secondary Collision Brake
Do not overly rely on the Secondary Col-
lision Brake. This system is designed to help reduce the possibility of further damage due to a secondary collision,
however, that effect changes according to various conditions. Overly relying on the system may result in death or serious
injury.
■Replacing tires
Make sure that all tires are of the speci-
fied size, brand, tread pattern and total load capacity. In addition, make sure that the tires are inflated to the recom-
mended tire inflation pressure level.
The ABS, TRC and VSC systems will not
function correctly if different tires are installed on the vehicle.
Contact any authorized Lexus retailer or Lexus authorized repairer, or any reliable
repairer for further information when replacing tires or wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect the driving assist systems, and may cause a
system to malfunction.

6-1. Maintenance and care
6-1.Maintenance and care
Working from top to bottom, liber-
ally apply water to the vehicle body,
wheel wells and underside of the
vehicle to remove any dirt and dust.
 Wash the vehicle body using a
sponge or soft cloth, such as a
chamois.
 For hard-to-remove marks, use car
wash soap and rinse thoroughly with
water.
 Wipe away any water.
 Wax the vehicle when the water-
proof coating deteriorates.
If water does not bead on a clean surface,
apply wax when the vehicle body is cool.
■CFRP (Carbon Fiber Reinforced Plas- tic) part (if equipped)
●As the CFRP parts may change color if they are exposed to ultraviolet rays for
extended periods of time, Lexus recom- mends that your vehicle be stored in a place where it will not be exposed to
direct sunlight.
●Do not use wax that contains abrasives.
●Do not use automatic car washes as they may scratch the CFRP parts and damage
the paint.
■Self-restoring coat*
The vehicle body has a self-restoring coat-
ing that is resistant to small surface scratches caused in a car wash etc.
●The coating lasts for 5 to 8 years from when the vehicle is delivered from the plant.
●The restoration time differs depending on the depth of the scratch and outside tem-
perature. The restoration time may become shorter when the coating is warmed by
applying warm water.
●Deep scratches caused by keys, coins,
etc. cannot be restored.
●Do not use wax that contains abrasives.
*: CFRP parts (if equipped) do not have a
self-restoring coat.
■Cleaning the areas with metal accents
Do not use baking soda (sodium bicarbon-
ate) and wax that contains abrasives.
■Automatic car washes (vehicles without CFRP parts)
●Fold the mirrors before washing the vehi-cle. Start washing from the front of the vehicle. Make sure to extend the mirrors
before driving.
●Wash the vehicle with the active rear wing retracted. If the vehicle is washed with the active rear wing raised, depend-
ing on the type of automatic car wash, the brushes of the automatic car wash may become stuck on the active rear wing. In
this case, the active rear wing may not be washed very well or may even be scratched or damaged.
●Brushes used in automatic car washes may scratch the vehicle body and dam-
age the paint.
■High pressure car washes
●Do not allow the nozzles of the car wash
to come within close proximity of the win- dows.
●Before using the car wash, check that the fuel filler door on your vehicle is closed properly.
Cleaning and pr otecting the
vehicle exterior
Perform cleaning in a manner

display. (P.92)
The illustration used is intended as an
example, and may differ from the image
that is actually displayed on the multi-infor-
mation display.
■Routine tire inflation pressure checks
The tire pressure warning system does not
replace routine tire inflation pressure checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.
■Situations in which the tire pressure warning system may not operate prop-
erly
●In the following cases, the tire pressure
warning system may not operate prop- erly.• If non-genuine Lexus wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equipment) tire.• A tire has been replaced with a tire that is
not of the specified size. • Tire chains etc. are equipped.• An auxiliary-supported run-flat tire is
equipped. • If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehi- cle, particularly around the wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.• If wheels without tire pressure warning
valves and transmitters are used. • If the ID code on the tire pressure warn-ing valves and transmitters is not regis-
tered in the tire pressure warning
computer.
●Performance may be affected in the fol-
lowing situations. • Near a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility that generates strong radio waves or electrical noise• When carrying a portable radio, cellular
phone, cordless phone or other wireless communication device
If tire position information is not correctly
displayed due to the radio wave conditions,
the display may be corrected by driving and
changing the radio wave conditions.
●When the vehicle is parked, the time taken for the warning to start or go off
could be extended.
●When tire inflation pressure declines rap-
idly for example when a tire has burst, the warning may not function.
■Warning performance of the tire pres-sure warning system
The warning of the tire pressure warning system will change in accordance with the
conditions under which it was initialized. For this reason, the system may give a warning
even if the tire pressure does not reach a low enough level, or if the pressure is higher than the pressure that was adjusted to when
the system was initialized.
