1-3. Adjustable components (seats, mirrors, steering wheel, etc.)
Before driving
Driving position memory system
Your preferred driving position (the po sition of the driver’s seat, steering
wheel and outside rear view mirrors) can be entered into the computer’s
memory and recalled with the touch of a button.
Two different driving positions can be entered into memory.
■ Entering a positi on into memory
Check that the shift lever is set in “P”.
Turn the engine switch to the “ON” position.
Adjust the driver’s seat, steering wheel, and outside rear view
mirrors to the desired positions. While pushing the “SET” button,
push button “1” or “2” until the
signal beeps.
If the selected button has
already been preset, the previ-
ously recorded position will be
overwritten.

1-3. Adjustable components (seats, mirrors, steering wheel, etc.)
■Retained accessory power
Each memorized position (except for the tilt and telescopic steering column) can
be activated within 30 seconds after the driver’s door is opened, even if the key is
not in the engine switch.
■If any position memory button is pushed while the adjustments are being made
The operation will stop. To reactivate the system, push the button again.
■If the battery is disconnected
The memorized positions must be reset because the computer’s memory is erased
when the battery is disconnected.
CAUTION
■Seat adjustment caution
Take care during seat adjustment that the seat does not strike the rear passenger or
squeeze your body against the steering wheel.
If this happens, you can stop the movement by pressing another seat position mem-
ory button.
■ Recalling the memorized position
Check that the shift lever is set in “P”.
Turn the engine switch to the “ON” position. Push button “1” or “2” to recall
the desired position.

1-6. Theft deterrent system
Alarm
Deactivating or stopping the alarmDo one of the following:
● Unlock the doors using the key or the wireless remote control.
● Start the engine.
■Items to check before locking the vehicle
To prevent unintended triggering of the alarm, check that there is no one in the vehi-
cle, and that all windows and the moon roof are closed before locking the vehicle.
■When the battery is disconnected
Be sure to cancel the alarm system.
If the battery is discharged before canceling the alarm, the system may be triggered
when the battery is reconnected.
The system sounds the alarm and flashes lights when forcible entry is
detected.
To arm the alarm, exit the vehi-
cle, make sure that the doors
and hood are closed, and lock
all the doors.
The system will operate auto-
matically once the indicator
begins to flashing.

2-1. Driving procedures
CAUTION
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the engine running.
This prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator
pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal willresult in sudden acceleration that may lead to an accident that could result in
death or serious injury.
• When backing up, you may twist your body around, leading to a difficulty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle only slightly, allowing you to depress the brake and accelerator pedals prop-
erly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay response in an emergency, resulting in an acci-
dent.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
●Do not let the vehicle roll backwards while the shift lever is in a driving position, or
roll forward while the shift lever is in “R”.
Doing so may result in an accident or damage to the vehicle.
●If the smell of exhaust is noticed inside the vehicle, open the windows and check
that the back door is closed.
Large amounts of exhaust in the vehicle can cause driver drowsiness and an acci-
dent, resulting in death or a serious health hazard. Have the vehicle inspected by
your Lexus dealer immediately.
●Do not under any circumstances shift the sh ift lever to “P”, “R” or “N” while the
vehicle is moving.
Doing so can cause significant damage to the transmission system and may result
in a loss of vehicle control.

When driving
CAUTION
■When driving the vehicle
●Do not shift the shift lever to “N” while the vehicle is moving.
Doing so may cause insufficient engine braking and lead to an accident.
●Do not turn the engine off while driving.
The power steering and brake booster systems will not operate properly if the
engine is off.
●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 2 3 )
●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.
●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
death or serious 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.
●If you drive through deep water over about 28 in. (700 mm) in depth, select the
vehicle height in the “HI” (high) mode using the active height select switch and
then turn off the active height control suspension by pushing the height control
switch. Drive your vehicle at 19 mph (30 km/h) or slower.

2-1. Driving procedures
CAUTION
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce
your ability to control the vehicle, resulting in an accident.
●Sudden changes in engine speed, such as engine braking caused by up-shifting
or down-shifting, may 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
functioning properly. If the brakes on only one side are wet and not functioning
properly, steering control may be affected, resulting in an accident.
■When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident and result in death or serious injury.
■When the vehicle is stopped
●Do not race the engine.
If the vehicle is in any gear other than “P” or “N” the vehicle may accelerate sud-
denly and unexpectedly, and may cause an accident.
●Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and
check that exhaust fumes do not enter the vehicle interior.
●Always keep a foot on the brake pedal while the engine is running to prevent an
accident caused by the vehicle moving.

When driving
CAUTION
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehi-
cle when it is in the sun.
Failure to do so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plasticmaterial of eye glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of the vehicle, and may also cause a short circuit in the vehicle’s electrical com-
ponents.
●Always apply the parking brake, shift the shift lever to “P”, stop the engine and
lock the vehicle.
Do not leave the vehicle unattended while the engine is running.
●Do not touch the exhaust pipe while the engine is running or immediately after
turning the engine off.
Doing so may cause burns.
●Do not leave the engine running in an area with snow build-up, or where it is
snowing. If snowbanks build up around the vehicle while the engine is running,
exhaust gases may collect and enter the vehicle. This may lead to death or a seri-
ous health hazard.
■Exhaust gases
Exhaust gases include harmful carbon monoxide (CO) that is colorless and odor-
less. Inhaling exhaust gases may lead to death or a serious health hazard.
●If the vehicle is in a poorly ventilated area, turn the engine off. In a closed area,
such as a garage, exhaust gases may collect and enter the vehicle. This may lead
to death or a serious health hazard.
●The exhaust should be checked occasionally. If there is a hole or crack caused by
corrosion, damage to a joint or abnormal exhaust noise, be sure to have the vehi-
cle inspected and repaired by your Lexus dealer. Failure to do so may allow
exhaust gases to enter the vehicle, resulting in death or a serious health hazard.

■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for a long
time.
Doing so may damage the power steering pump.
●When driving over bumps in the road, drive as slowly as possible to avoid damag-
ing the wheels, underside of the vehicle, etc.
■If you hear a squealing or scraping noise (brake pad wear limit indicators)
Have your Lexus dealer check and replace the brake pads as soon as possible.
The rotor damage can result if the pads are not replaced when needed.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel
firmly and gradually press the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds.
●The vehicle will behave abnormally.
Replace a flat tire with a new one. ( →P. 3 9 1 )
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the
following serious damage to the vehicle.
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to
have your Lexus dealer check the following.
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, transmission,
transfer, differentials, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints (where
possible) and the function of all joints, bearings, etc.
