Auto current cut-off function
In case of over current, the auto cut-off fu nction stops the power flowing to the trailer
lights to prevent damage to th e vehicle’s electrical system.
This function is activated when the rated curren t of any of the following trailer light circuit
components is exceeded: ●
Tail lights: maximum 7.8 A ●
Stop/turn signal light (right): maximum 4.5 A ●
Stop/turn signal light (left): maximum 4.5 A ■
When the auto current cut function is activated
If a trailer light does not come on due to the activation of the auto current cut function,
the light system will need to be reset.
Follow the reset procedure shown below. ●
If a tail light does not come on, turn off the headlight switch. ●
If the right-side stop/turn signal light does not come on, put the turn signal in the off
position or remove foot from the brake pedal. ●
If the left-side stop/turn signal light does not come on, put the turn signal in the off posi-
tion or remove foot from the brake pedal.
If the emergency flashers do not operate, press the emergency flasher switch to turn
them off.
After the light system is reset, operate the light switches again to see if the lights operate
normally.
If the lights do not operate normally, have the vehicle inspected by your Lexus dealer.Connecting trailer lights

Repair and replacement
It is recommended that genuine Lexus parts be used for repairs to ensure performance
of each system. If non-Lexus parts are used in replacement or if a repair shop other than
a Lexus dealer performs repairs, confirm the warranty coverage. ■
Resetting the message indicating main tenance is required (U.S.A. only)

Lexus technicians are well-trained specialists an d are kept up to date with the latest ser-
vice information. They are well informed about the operation of all systems on your
vehicle. ●
Keep a copy of the repair order. It proves that the maintenance that has been per-
formed is under warranty coverage. If any problem should arise while your vehicle is
under warranty, your Lexus dealer will promptly take care of it.

Used engine oil ●
Used engine oil contains potentially harm ful contaminants which may cause skin dis-
orders such as inflammation and skin canc er, so care should be taken to avoid pro-
longed and repeated contact. To remove used engine oil from your skin, wash
thoroughly with soap and water. ●
Dispose of used oil and filters only in a sa fe and acceptable manner. Do not dispose of
used oil and filters in household trash, in sewers or onto the ground. Call your Lexus
dealer, service station or auto parts store for information concerning recycling or dis-
posal. ●
Do not leave used engine oil within the reac h of children.
NOTICE ■

Tire types ●
Summer tires
Summer tires are high-speed performance tires best suited to highway driving under
dry conditions. Since summer tires do not have the same traction performance as
snow tires, summer tires are inadequate for driving on snow-covered or icy roads. For
driving on snow-covered roads or icy roads, the use of snow tires is recommended.
When installing snow tires, be sure to replace all four tires. ●
All season tires
All season tires are designed to provide better traction in snow and to be adequate for
driving in most winter condit ions as well as for use year-round. All season tires, how-
ever, do not have adequate traction performance compared with snow tires in heavy
or loose snow. Also, all season tires fall short in acceleration and handling perfor-
mance compared with summer tires in highway driving. ●
Snow tires
For driving on snow-covered roads or icy roads, we recommend using snow tires. If
you need snow tires, select tires of the same size, construction and load capacity as the
originally installed tires. Since your vehicle has radial tires as original equipment, make
sure your snow tires also have radial cons truction. Do not install studded tires without
first checking local regulations for possible re strictions. Snow tires should be installed
on all wheels. (  P. 3 9 0 )■
Initializing the tire pressure warning system
Initialize the system with the tire inflation pressure adjusted to the specified level. ■
If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost. ■
If you press the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire inflation pressure to the specified level and ini-
tialize the tire pressure warning system again.

Situations in which the tire pressure warning system may not operate properly ●
In the following cases, the tire pressure warning system may not operate properly.
• 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.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the wheels or wheel
housings.
• If the tire inflation pressure is extremely higher than the specified level.
• If wheel without the tire pressure warning valve and transmitter is used.
• If the ID code on the tire pressure warning valves and transmitters is not registered
in the tire pressure warning computer. ●
Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large display, air-
port or other facility th at generates strong radio waves or electrical noise.
• When carrying a portable radio, cellular phone, cordless ph one or other wireless
communication device.
If tire position information is not correctl y 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 rapidly for example when a tire has burst, the
warning may not function. ■
The initialization operation ●
Make sure to carry out initialization af ter adjusting the tire inflation pressure.
Also, make sure the tires are cold before carry ing out initialization or tire inflation pres-
sure adjustment. ●
If you have accidentally turned the power swit ch off during initializat ion, it is not neces-
sary to press the reset switch again as init ialization will restart automatically when the
power switch has been turned to ON mode for the next time. ●
If you accidentally press the reset switch when initialization is not necessary, adjust the
tire inflation pressure to the specified leve l when the tires are co ld, and conduct initial-
ization again. ●
While the position of each tire is being de termined and the inflation pressures are not
being displayed on the mu lti-information display, if the in flation pressure of a tire drops,
the tire pressure warning light will come on.

Warning performance of the tire pressure warning system
The warning of the tire pressure warning syst em will change in accordance with the con-
ditions 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. ■
When initialization of the tire pressure warning system has failed
Initialization may take longer to complete if the vehicle is driven on an unpaved road.
When performing initialization, drive on a pa ved road if possible. Depending on the driv-
ing environment and condition of the tires, initialization will be completed in approxi-
mately 10 to 30 minutes. If initialization is not complete af ter driving approximately 10 to
30 minutes, continue driving for a while.
If the inflation pressure of each tire is not displayed after driving for approximately 1 hour,
perform the following procedure. ●
Park the vehicle in a safe place for approxim ately 20 minutes. Then drive straight (with
occasional left and right turns) at approximately 25 mph (40 km/h) or more for
approximately 10 to 30 minutes.
However, in the following situations, the tire inflation pressure will not be recorded and
the system will not operate properly. Perform initialization again. ●
When operating the tire pressure warning reset switch, the tire pressure warning light
does not blink 3 times. ●
After performing initialization, the tire pres sure warning light blinks for 1 minute then
stays on while driving.
If the inflation pressure of each tire is st ill not displayed, have the vehicle inspected by
your Lexus dealer.
