2224-1. Before driving
GS350_250_OM_OM30E16E_(EE)
CAUTION
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift lever or
depress the accelerator pedal, this could cause an accident or fire due to engine
overheating. Additionally, if the vehicle is parked in a poorly ventilated area,
exhaust gases may collect and enter the vehicle, leading to death or a serious
health hazard.
■When braking
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause one side
of the vehicle to brake differently than the other side. Also, the parking brake may
not securely hold the vehicle.
●If the power brake assist function does not operate, do not follow other vehicles
closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be depressed
more firmly than usual. Also, the braking distance will increase. Have your brakes
fixed immediately.
●The brake system consists of 2 individual hydraulic systems; if one of the systems
fails, the other will still operate. In this case, the brake pedal should be depressed
more firmly than usual and the braking distance will increase. Have your brakes
fixed immediately.
■If the vehicle becomes stuck (AWD models)
Do not spin the wheels excessively when any of the tires is up in the air, or the vehi-
cle is stuck in sand, mud, etc. This may damage the driveline components or propel
the vehicle forward or backward, causing an accident.

GS350_250_OM_OM30E16E_(EE)
Hill-start assist control
To engage hill-start assist control,
further depress the brake pedal
when the vehicle is stopped com-
pletely.
A buzzer will sound once to indicate
the system is activated. The slip indica-
tor will also start flashing.
■Hill-start assist control operating conditions
●The system operates in the following situations:
• The shift lever is in a position other than P.
• The parking brake is not applied.
• The accelerator pedal is not depressed.
●Hill-start assist control cannot be operated while the slip indicator light is illumi-
nated.
■Hill-start assist control
●While hill-start assist control is operating, the brakes remain automatically applied
after the driver releases the brake pedal. The stop lights and the high mounted
stoplight turn on.
●Hill-start assist control operates for about 2 seconds after the brake pedal is
released.
●If the slip indicator does not flash and the buzzer does not sound when the brake
pedal is further depressed, slightly reduce the pressure on the brake pedal (do not
allow the vehicle to roll backward) and then firmly depress it again. If the system still
does not operate, check that the operating conditions explained above have been
met.
Assists with starting off and tempo rarily maintains braking power even
if the foot is removed from the brake pedal when starting off on an
incline or a slippery slope.

■Hill-start assist control buzzer
●When hill-start assist control is activated, the buzzer will sound once.
●In the following situations, hill-start assist control will be canceled and the buzzer
will sound twice.
• No attempt is made to drive the vehicle within approximately 2 seconds ofreleasing the brake pedal.
• The shift lever is moved to P.
• The parking brake is applied.
• The brake pedal is depressed again.
• The brake pedal has been depressed for more than approximately 3 minutes.
■If the slip indicator comes on
It may indicate a malfunction in the system. Contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
CAUTION
■Hill-start assist control
●Do not overly rely on hill-start assist control. Hill-start assist control may not oper-
ate effectively on steep inclines and roads covered with ice.
●Unlike the parking brake, hill-start assist control is not intended to hold the vehi-
cle stationary for an extended period of time. Do not attempt to use hill-start
assist control to hold the vehicle on an incline, as doing so may lead to an acci-
dent.
