2-1. Driving procedures
CAUTION
●Do not adjust the positions of the steering wheel, the seat, or the inside or outside
rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents, resulting
in death or serious injury.
●Always check that all occupants’ arms, heads and other body parts are not out-
side the vehicle, as this may result in death or serious injury.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steer ing may cause tire slippage and reduce
your ability to control the vehi cle, resulting in an accident.
●Sudden changes in engine speed, such as engine braking caused by up-shifting
and down-shifting, may cause the vehicle to skid, resulting in an accident.
●After driving through a pudd le, lightly depress the brake pedal to make sure that
the brakes are functioning properly. Wet brake pads may prevent the brakes from
functioning properly. If the brakes on on ly one side are wet and not functioning
properly, steering control may be af fected, resulting in an accident.
■When operating the paddle shift switches/reverse selector switch
Do not operate the paddle shift switches or reverse selector switch with the accel-
erator pedal depressed and Neutral selected.
Doing so may lead to unexpected rapid acceleration of the vehicle that may cause
an accident and result in death or serious injury.
■If a brake pad wear warning message is displayed
Have your Lexus dealer check and replac e the brake pads as soon as possible.
The disc damage can result if the pads are not replaced when needed.
Moderate levels of the brake pad and disc wear allow enhanced braking power. As
a result, the discs may wear more quickly than conventional brake discs. Therefore,
when replacing the brake pads, Lexus recommends that you also have the thick-
ness of the discs measured.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or
those of the brake discs are exceeded.

When driving
CAUTION
■Exhaust gases
Exhaust gases include harmful carbon monoxide (CO), which is colorless and
odorless. Inhaling exhaust gases may lead to death or a serious health hazard.
●If the vehicle is in a poorly ventilated ar ea, stop the engine. In a closed area, such
as a garage, exhaust gases may collect and enter the vehicle. This may lead to
death or a serious health hazard.
●The exhaust system should be checked occasionally. If there is a hole or crack
caused by corrosion, damage to a joint or abnormal exhaust noise, be sure to
have the vehicle inspected and repaired by your Lexus dealer. Failure to do so
may allow exhaust gases to enter the vehicl e, resulting in death or a serious health
hazard.
■When taking a nap in the vehicle
Always turn the engine off. If you take a nap with the engine on, you may acciden-
tally depress the accelerator and an accident or fire may occur due to engine over-
heating. In addition, if the vehicle is parked in a poorly ventilated area, exhaust gases
may enter the vehicle, leading to death or a serious health hazard.
■When braking the vehicle
●Be especially careful if the brakes are wet, such as when driving on wet or snowy
roads or immediately after washing the vehicle. When the brakes are wet, their
efficiency may be reduced and the vehicle may brake unevenly to the left or right.
The efficiency of the parking brake may also be reduced.
●The brake system consists of 3 individual hydraulic systems; if one of the systems
fails, the others will still operate. In th is case, the brake pedal should be depressed
more firmly than usual and the braking distance will increase. If this happens, do
not continue to drive the vehicle. If the brake system warning light (red indicator)
comes on together with the buzzer sound while driving, immediately stop the
vehicle in a safe place and contact your Lexus dealer.

2-1. Driving procedures
■When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. (P. 325, 327)
Depending on the condition, the parking brake indicator light may flash.
NOTICE
■When parking the vehicle
Before you leave the vehicle, set the parking brake, select 1st gear or Reverse, and
stop the engine. Make sure that the vehicle does not move.
■When the system malfunctions
Stop the vehicle in a safe place and check the warning messages.
■When the parking brake cannot be released due to a malfunction
Use the parking brake release tool to manually release the parking brake.
(  P. 3 4 5 )
Driving the vehicle with the parking brake set will lead to brake components over-
heating, which may affect braking performance and increase brake wear.

■Warning lights
Warning lights inform the driver of ma lfunctions in any of the vehicle’s
systems. ( P. 312)
*1: These lights turn on when the ignition switch is turned to the “ON” position
to indicate that a system check is being performed. They will turn off after the
engine is started, or after a few seconds. There may be a malfunction in a sys-
tem if a light does not come on, or if th e lights do not turn off. Have the vehi-
cle inspected by your Lexus dealer.
*2: The display flashes to indicate that the engine oil temperature is too high.
*3: These displays flash to indicate that the engine coolant temperature is too
high.

CAUTION
■If a safety system warning light does not come on
Should a safety system lig ht such as the ABS or SRS warning light not come on
when you start the engine, this could mean that these systems are not available to
help protect you in an accident, which could result in death or serious injury. Have
the vehicle inspected by your Lexus dealer immediately if this occurs.

Maintenance and care
Initializing the tire pressure warning systemThe tire pressure warning system must be initialized when the tire infla-
tion pressure is changed (such as when changing traveling speed).
When the tire pressure warning system is initialized, the current tire infla-
tion pressure is set as the benchmark pressure.
■ How to initialize the tire pressure warning system
Park the vehicle in safe place and turn the ignition switch off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( P. 366)
Make sure to adjust the tire pressure to the specified cold tire inflation
pressure level. The tire pressure warning system will operate based on
this pressure level.
Turn the ignition switch to the “ON” position.
Press and hold the tire pressure
warning reset switch until the tire
pressure warning light flashes
slowly 3 times.
Wait for a few minutes with th e ignition switch in the “ON” posi-
tion and then turn the ignition switch off.

4-3. Do-it-yourself maintenance
Registering ID codesThe tire pressure warning valve and transmitter is equipped with a unique
ID code. When replacing a tire pressu re warning valve and transmitter, it
is necessary to register the ID code. Ha ve the ID code registered by your
Lexus dealer.
■When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to expose the
fabric or bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the size or
location of a cut or other damage
If you are not sure, consult with your Lexus dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not registered,
the tire pressure warning system will not work properly. After driving for about 20
minutes, the tire pressure warning light fl ashes for 1 minute to indicate a system mal-
function.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if they
have seldom or never been used or damage is not obvious.
■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.
■Tire rotation
It is not possible to rotate the tires, as each tire is designed only for its original posi-
tion on the vehicle.
