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 when-
ever the parking brake shoes and/or drum are replaced. Have any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional
perform the bedding down operation.
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availabil-
ity of the correct fuel. (P. 929)
For efficient use
Shift the shift lever to D when driving.
In the N position, the gasoline engine operates but electricity cannot be gen-
erated. The hybrid battery (traction battery) will discharge, requiring unnec-
essary engine power to recharge.
Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration and decel-
eration will make more effective use of the electric motor (traction motor)
without having to use gasoline engine power.
Avoid repeated acceleration.
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving
with the accelerator pedal slightly released.
Shift the shift lever to P when parking.
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the shift lever in the N position for an extended period of time may
discharge the hybrid battery (traction battery). The vehicle cannot run if the
hybrid battery (traction battery) is discharged.
