4-1. Before driving
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. 521)
Brake pads and discs
■
F SPORT models of GS350/GS300, 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 vehicle environment (temperature,
humidity, etc.).
GS F: In order to achieve steady braking performance even during high-load sporty
●
driving, brake pads that include a large amount of iron are used. As a result, rust may
form if the vehicle is parked for a long time with wet brake pads or disc rotors, causing
them to stick. When parts are stuck, abnormal noise or vibration may occur during
driving, so lightly depress the accelerator pedal and drive slowly. (Before parking the
vehicle after it is washed, drive slowly and apply the brakes several times to dry the
parts.)
Idling time before engine stop (GS300)
■
To prevent damage to the turbocharger, allow the engine to idle immediately after high-
load driving.
Normal city driving or high-speed driving (at the high-
way speed limit or recommended speed)
Steep hill driving or continuous driving (race track driv-
ing etc.)
