NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator of the tachometer enter the red zone, as it represents the
engine speed range which exceeds the maximum safe engine speed.
●In the following situations, the engine may be overheating. In this case, immediately
stop the vehicle in a safe place, and check the engine after it has cooled completely.
(→ P. 5 9 6 )
• The engine coolant temperature gauge indicator ( ) is in the red zone and flash- ing.
• The engine oil temperature gauge indicator ( ) is in the red zone and flashing.

Operation of each component
GS350_200t_GS F_OM_OM30E87E_(EE)
■Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from receiving radio waves.
■Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following situations, the
communication between the electronic key and the vehicle may be affected, preventing
the smart entry & start system, wireless remote control and engine immobilizer system
from operating properly. (Ways of coping: →P. 5 8 8 )
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display, airport or
other facility that generates strong radio waves or electrical noise
●When the electronic key is in contact wi th, or is covered by the following metallic
objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When other wireless keys (that emit radio waves) are being used nearby
●When carrying the electronic key together with the following devices that emit radio
waves
• When carrying a portable radio, cellular phone, cordless phone or other wireless communication device
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic content or me tallic objects are attached to the rear win-
dow
●When the electronic key is placed near a battery charger or electronic devices
Press twice while pressing and holding
. Confirm that the electronic key indica-
tor flashes 4 times.
While the battery-saving mode is set, the smart
entry & start system cannot be used. To cancel
the function, press any of the electronic key but-
tons.

Driving
GS350_200t_GS F_OM_OM30E87E_(EE)
NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time during driving, as
this may restrain the engine output.
●Do not use the accelerator pedal or depress the accelerator and brake pedals at the
same time to hold the vehicle on a hill.
■When parking the vehicle
Always shift the shift lever to P. Failure to do so may cause the vehicle to move or the
vehicle may accelerate suddenly if the accelerator pedal is accidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for an
extended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid damaging
the wheels, underside of the vehicle, etc.
●GS200t: Make sure to idle the engine immediately after high speed driving or hill
climbing. Stop the engine only after the turbocharger has cooled down. ( →P. 2 2 4 )
Failure to do so may cause damage to the turbocharger.
■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 depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( →P. 5 5 1 , 5 6 7 )
■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
any authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, transmission,
transfer (AWD models), differential, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints (where
possible), and the function of all joints, bearings, etc.

3824-6. Driving tips
GS350_200t_GS F_OM_OM30E87E_(EE)
Winter driving tips
●Use fluids that are appropriate to the prevailing outside temperatures. •Engine oil
• Engine coolant
•Washer fluid
●Have a service technician inspect the condition of the battery.
●Have the vehicle fitted with four snow tires or purchase a set of tire chains for
the rear tires.
*
Ensure that all tires are the specified size and brand, and that chains match the size of
the tires.
*: Tire chains cannot be mounted on vehicles with front and rear tires of differing sizes
●Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine coolant
•Washer fluid
●Have a service technician inspect the condition of the battery.
●Have the vehicle fitted with four snow tires.
Ensure that all tires are the specified size and brand.
Carry out the necessary preparations and inspections before driving the vehi-
cle in winter. Always drive the vehicle in a manner appropriate to the prevail-
ing weather conditions.

WA R N I N G
The engine compartment contains many mechanisms and fluids that may move suddenly,
become hot, or become electrically energized. To avoid death or serious injury, observe
the following precautions.
■When working on the engine compartment
●Keep hands, clothing and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc. right after driving
as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel or
the battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous and corro-
sive sulfuric acid.
●Take care because brake fluid can harm your hands or eyes and damage painted sur-
faces. If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately. If you still experience discomfort, consult a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant temperature is high.
( → P. 4 6 0 )
■Safety glasses
Wear safety glasses to prevent flying or fallin g material, fluid spray, etc. from getting in
your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt
in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or when
the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.
