■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake system
needs bedding-down of the brake shoes periodically or whenever the parking brake
shoes and/or drum are replaced. Have your Lexus dealer perform the bedding down
operation.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration
laws and confirm the availability of the cor-
rect fuel. ( →P. 5 4 1 )
■Brake pads and discs (F SPORT models of GS350/GS200t, and GS F)
The brake pads and discs are designed for use under high load conditions. Therefore,
brake noise may be generated depending on the vehicle speed, braking force and vehi-
cle environment (temperature, humidity, etc.).
■Idling time before engine stop (GS200t)
To prevent damage to the turbocharger, allow the engine to idle immediately after high-
speed driving or hill climbing.
Driving conditionIdling time
Normal city drivingNot necessary
High-speed driving (Constant speed of approx.
62 mph [100 km/h])Approximately 1 minute
Steep hill driving or continuous driving at 62 mph
(100 km/h) or more (race track driving etc.)Approximately 2 minute

Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce your
ability to control the vehicle.
●Sudden acceleration, engine braking due to shifting, or changes in engine speed
could cause the vehicle to skid, resulting in an accident.
●After driving through a puddle, lightly depress the brake pedal to make sure that the
brakes are functioning properly. Wet brake pads may prevent the brakes from func-
tioning properly. If the brakes on only one side are wet and not functioning properly,
steering control may be affected.
■When shifting the shift lever
●Do not let the vehicle roll backward while the shift lever is in a driving position, or roll
forward while the shift lever is in R.
Doing so may cause the engine to stall or lead to poor brake and steering perfor-
mance, resulting in an accident or damage to the vehicle.
●Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to a driving position while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Moving the shift lever to N while the vehicle is moving will disengage the engine from
the transmission. Engine braking is not available when N is selected.
●Be careful not to shift the shift lever with the accelerator pedal depressed. Shifting the
shift lever to a gear other than P or N may lead to unexpected rapid acceleration of
the vehicle that may cause an accident and result in death or serious injury.
■If you hear a squealing or scraping noise (brake pad wear limit indicators) (GS350/
GS200t)
Have the brake pads checked and replaced by your Lexus dealer as soon as possible.
Rotor damage may result if the pads are not replaced when needed.
Front brakes of F SPORT models: Moderate levels of brake pad and disc wear allow
enhanced front braking power. As a result, the discs may wear more quickly than con-
ventional brake discs. Therefore, when replacing the brake pads, Lexus recommends
that you also have the thickness 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.

Observe the following precautions.
Failure to do so may result in death or serious injury.
■If a brake pad wear warning message is displayed (GS F)
Have the brake pads checked and replaced by your Lexus dealer as soon as possible.
Rotor damage may 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 thickness 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 the vehicle is stopped
●Do not race the engine.
If the vehicle is any gear other than P or N, the vehicle may accelerate suddenly and
unexpectedly, causing an accident.
●In order to prevent accidents due to the vehicle rolling away, always keep depressing
the brake pedal while the engine is running, and apply the parking brake as neces-
sary.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, alwa ys depress the brake pedal and securely
apply the parking brake as needed.
●Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause the exhaust
system to overheat, which could result in a fire if combustible material is nearby.

Maintenance and care
■Checking fluid level
The brake fluid level should be between the “MAX” and “MIN” lines on the
tank.
■Adding fluid
Make sure to check the fluid type and prepare the necessary item.
■Brake fluid can absorb moisture from the air
Excess moisture in the brake fluid can cause a dangerous loss of braking efficiency. Use
only newly opened brake fluid.
Brake fluid
XGS350/GS200t XGS F
Fluid typeFMVSS No.116 DOT 3 or SAE J1703 brake fluid
Items Clean funnel
WA R N I N G
■When filling the reservoir
Take care as brake fluid can harm your hands and eyes and damage painted surfaces. If
fluid gets on your hands or in your eyes, fl ush the affected area with clean water imme-
diately. If you still experien ce discomfort, see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear out or
when the fluid level in the accumulator is high.
If the reservoir needs frequent ref illing, there may be a serious problem.
