When driving
GS_G_U (OM30C11U)
October 28, 2011 5:15 pm
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially
slippery.
●Refrain from high speeds when driving on an expressway in the rain, because
there may be a layer of water between the tires and the road surface, preventing
the steering and brakes from operating properly.
■Breaking in your new Lexus
To extend the life of the vehicle, the following precautions are recommended to
observe:
●For the first 186 miles (300 km):
Avoid sudden stops.
●For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low range in the “S” position.
• Do not drive at a constant speed for extended periods.
■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 drums are replaced.
Have your Lexus dealer perform the bedding-down.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
correct fuel. (→P. 5 8 7 )
■When starting on an incline
The hill-start assist control may operate. ( →P. 199)
■Overheating
Your vehicle may overheat under the following extreme driving conditions:
●When driving on a long uphill road in hot weather
●Suddenly decelerating or stopping the vehicle immediately after high-speed
driving

CAUTION
■When driving the vehicle
●Do not shift the shift lever to “D” 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.
●During normal driving, do not turn off the engine. Turning the engine off while
driving will not cause loss of steering or braking control, but the power assist to
these systems will be lost. This will make it more difficult to steer and brake, so you
should pull over and stop the vehicle as soon as it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible to stop
the vehicle in the normal way: → P. 5 8 2
●Use engine braking (downshift) to maintain a safe speed when driving down a
steep hill.
Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness. (→P. 1 3 9 )
●When stopped on an inclined surface, use the brake pedal and parking brake to
prevent the vehicle from rolling backward or forward and causing an accident.
●Be careful when driving on slippery surfaces, as the vehicle may spin or skid when
downshifting, rapidly accelerating, braking or turning.
●Do not adjust the position 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 that may
result in death or serious injury.
●Always check that all passengers’ arms, heads or other parts of their bodies are
not outside the vehicle, as this may result in death or serious injury.
●Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do
not drive over 85 mph (140 km/h) unless your vehicle has high-speed capability
tires. Driving over 85 mph (140 km/h) may result in tire failure, loss of control and
possible injury. Be sure to consult a tire dealer to determine whether the tires on
your vehicle are high-speed capability tires or not before driving at such speeds.

CAUTION
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, you may accidentally move the shift lever or
depress the accelerator pedal, which 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 the vehicle
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and 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 brake actuator (GS460) or brake booster (GS350) does not operate, do
not follow other vehicles closely and avoid hills or sharp turns that require brak-
ing.
In this case, braking is still possible, but it will require more force on the pedal than
usual. Braking distance may also increase.
●Do not pump the brake pedal if turning the engine off.
Each push on the brake pedal uses up the reserve for the power-assisted brakes.
●The brake system consists of 3 (GS460) or 2 (GS350) individual hydraulic sys-
tems: 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 braking distance becomes
longer.
Do not drive your vehicle with only a single brake system. Have your brakes fixed
immediately.
■If the vehicle becomes stuck or bogged (4WD models)
Do not spin the wheels recklessly when any of the tires is up in the air, or stuck in
sand or mud, etc. This may damage the drive system components or propel the
vehicle forward (or in another direction) and cause an accident.

Intuitive parking assist∗
∗: If equipped
Intuitive parking assist uses sensors in the front and rear of the vehicle to
detect the distance between the vehicle and any obstacles, and informs the
driver of this distance using the mult i-information display, the touch screen,
and warning beeps.
The system may be used at speeds less than about 6 mph (10 km/h).
■ Sensor types
Dual sensors
There are 4 sensors installed in the front bumper, two in the center section
to detect obstacles directly ahead, and one in each corner of the bumper,
to detect obstacles in those areas.
The dual sensors detect obstacles ahead of the vehicle, and judge whether
avoidance maneuvers are necessary (whether the obstacle will come
within 0.8 ft. [25 cm] of the vehicle), according to the distance between
the obstacle and the vehicle, and the steering wheel position. The screen
display and beeps will change accordingly.
Rear corner sensors
These sensors detect obstacles around the rear corners of the vehicle.
Back sensors
These sensors detect obstacles behind the vehicle.

■Intuitive parking assist switch
Press the switch to turn the
system on/off.
If the intuitive parking assist is
turned on, the indicator light will
come on, and the system will
operate under the following
conditions:
• The dual sensors will oper- ate if the shift lever is in a
position other than “R” or
“P”.
• All corner sensors and the back sensors will operate if
the shift lever is in “R”.
