■Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop auto-
matically in the following conditions:
●During gasoline engine warm-up
●During hybrid battery (traction battery) charging
●During low or high hybrid battery (traction battery) temperature
■Charging the battery
●As the gasoline engine charges the hybrid battery (traction battery), the battery
does not need to be charged from an outside source. However, if the vehicle is
left parked for a long time the hybrid battery will slowly discharge. For this rea-
son, be sure to drive the vehicle at least once every few months for at least 30
minutes or 10 miles (16 km). If the hybrid battery becomes fully discharged and
you are unable to jump-start the vehicle with the 12 volt battery, contact your
Lexus dealer.
●If the shift lever is in “N”, the hybrid battery (traction battery) will not be
charged. When driving in heavy traffic, operate the vehicle with the shift lever in
“D” or “S” to avoid discharging the battery.
■After the 12 volt battery has discharged or has been changed or removed
The gasoline engine may not stop even if the vehicle is running on the hybrid battery
(traction battery). If this continues for a few days, contact your Lexus dealer.

The following sounds or vibrations may occur when the hybrid system is operating,
and are not a malfunction.
●Motor sounds may be heard from the engine compartment.
●Sounds may be heard from the hybrid battery (traction battery) behind the rear
seat when the hybrid system starts or stops.
●Sounds from the hybrid system may be heard when the trunk lid is open.
●Sounds may be heard from the transmission when the hybrid system starts or
stops.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard from the regenerative brake when you press the brake
pedal.
●Vibration may be felt when the gasoline engine starts or stops.
●You may hear cooling fan sounds coming from the air intake vents behind the
rear seat.

■Hybrid battery air vent
Hybrid battery air vent
There is an air intake vent on the
package tray for the purpose of
cooling the hybrid battery (trac-
tion battery). If the vent becomes
blocked, the hybrid battery may
overheat, leading to a reduction in
hybrid battery output.
Emergency shut off system
The emergency shut off system blocks off the high voltage current and
stops the fuel pump to minimize the risk of electrocution and fuel leakage
when a certain level of impact is detected by the impact sensor. If the
emergency shut off system activates, your vehicle will not restart. To
restart the hybrid system, contact your Lexus dealer.

April 27, 2009 10:09 am
Unlock the doors using the wireless remote control and open one of the
doors.
If a door is not opened within 60 seconds after is pressed, the doors
will be locked again and the alarm will automatically be set.
In case that the alarm is triggered, immediately stop the alarm. (→P. 9 8 )
■Battery-saving function
In the following circumstances, the entry function is disabled in order to prevent the
vehicle and electronic key batteries from discharging.
●When the entry function has not been used for a month or more
●When the electronic key has been left within approximately 3 ft. (1 m) of the
vehicle for 10 minutes or more
The system will resume operation when...
●The vehicle is locked using the door handle lock switch
●The vehicle is locked/unlocked using the wireless remote control function
( → P. 51) or the mechanical key ( →P. 5 5 0 )
■Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The card key battery life is about a year
and a half.)
●The battery becomes depleted even if the electronic key is not used because
the key always transmits radio waves. If the smart access system with push-but-
ton start or the wireless remote control does not operate, or the detection area
becomes smaller, the battery may be depleted. Replace the battery when nec-
essary.
( → P. 4 7 2 )
●To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) of
the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Glass top ranges
• Table lamps

■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.

CAUTION
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the hybrid system
operating. 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.
The exhaust system and exhaust gases can be extremely hot. This may cause a
fire if there is any flammable material nearby.
●Do not let the vehicle roll backwards while th e shift lever is in a driving position, or
roll forward while the shift lever is in “R”.
Doing so may cause the hybrid system not to operate or lead to poor brake and
steering performance, resulting 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 trunk is closed.
Large amounts of exhaust in the vehicle can cause driver drowsiness and an acci-
dent, resulting in death or a serious heal th 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 and may result in a
loss of vehicle control.
