801-2. Theft deterrent system
GS350_250_OM_OM30E16E_(EE)
Engine immobilizer system
The indicator light flashes after the
engine switch has been turned off to
indicate that the system is operating.
The indicator light stops flashing
after the engine switch has been
turned to ACCESSORY or IGNI-
TION ON mode to indicate that the
system has been canceled.
■System maintenance
The vehicle has a maintenance-free type engine immobilizer system.
■Conditions that may cause the system to malfunction
●If the grip portion of the key is in contact with a metallic object
●If the key is in close proximity to or touching a key to the security system (key with a
built-in transponder chip) of another vehicle
The vehicle’s keys have built-in transponder chips that prevent the
engine from starting if a key has not been previously registered in the
vehicle’s on-board computer.
Never leave the keys inside the ve hicle when you leave the vehicle.
This system is designed to help prevent vehicle theft but does not guar-
antee absolute security against all vehicle thefts.

seconds.)
■System maintenance

■Items to check before locking the vehicle
To prevent unexpected triggering of the alarm and vehicle theft, make sure of the fol-
lowing:

2324-1. Before driving
GS350_250_OM_OM30E16E_(EE)
■Tire information
●Increase the tire inflation pressure to 20.0 kPa (0.2 kgf/cm2 or bar, 3 psi) greater
than the recommended value when towing. ( →P. 6 4 5 )
●Increase the air pressure of the trailer tires in accordance with the total trailer
weight and according to the values recommended by the manufacturer of your
trailer.
■Trailer lights
●Please consult at any authorized dealer or repairer, or another duly qualified and
equipped professional when installing trailer lights, as incorrect installation may
cause damage to the vehicle’s lights. Please take care to comply with your state’s
laws when installing trailer lights.
●Check that the turn signal lights and stoplights are operating correctly every time
you hitch up the trailer. Directly wiring up to your vehicle may damage the electrical
system and stop the lights from functioning correctly.
■Break-in schedule
Lexus recommends that vehicles fitted with new power train components should not
be used for towing trailers for the first 800 km (500 miles).
■Safety checks before towing
●Check that the maximum load limit for the towing hitch/bracket and hitch ball is not
exceeded. Bear in mind that the coupling weight of the trailer will add to the load
exerted on the vehicle. Also make sure that the total load exerted on the vehicle is
within the range of the weight limits. ( →P. 2 2 8 )
●Ensure that the trailer load is secure.
●Supplementary outside rear view mirrors should be added to the vehicle if the traf-
fic behind cannot be clearly seen with standard mirrors. Adjust the extending arms
of these mirrors on both sides of the vehicle so that they always provide maximum
visibility of the road behind.
■Maintenance
●Maintenance must be performed more frequently when using the vehicle for tow-
ing due to the greater weight burden placed on the vehicle compared to normal
driving.
●Retighten all bolts securing the hitching ball and bracket after towing for approxi-
mately 1000 km (600 miles).

CAUTION
■Situations unsuitable for LKA
Do not use LKA in any of the following situations.
Otherwise, the system may not function correctly and could result in an accident.
●When driving with snow tires, tire chains, a spare tire, or similar equipment
●When the tires have been excessively worn, or when the tire inflation pressure is
low
●When there are objects or structures along the roadside that might be misinter-
preted as lane markers (such as guardrails, curb, reflector posts, etc.)
●When driving on snowy roads
●When pavement lane markers are difficult to see due to rain, snow, fog, sand, dirt,
etc.
●When there are visible lines on the pavement from road repairs, or if the remains
of old lane markers are still visible on the road
●When driving on slippery roads, such as those covered with rain, ice or snow
●When driving in a lane other than the driving or passing lanes on a freeway or
highway
●When driving on a road with lane closures due to maintenance, or when driving
in a temporary lane
●When towing a trailer
NOTICE
■To prevent damage to or incorrect operation of the LKA system
●Do not modify the headlights or attach stickers to the surface of the lights.
●Do not modify the suspension. If any suspension part needs to be replaced, con-
tact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
●Do not install or place anything on the hood or the grille. Also, do not install a
grille guard (bull bars, kangaroo bar etc.).
●Do not modify the sun visor. If any sun visor part needs to be replaced, contact
any authorized Lexus dealer or repairer, or another duly qualified and equipped
professional.
●If your windshield needs repairs, contact any authorized Lexus dealer or repairer,

4366-1. Maintenance and care
GS350_250_OM_OM30E16E_(EE)
Cleaning and protecting the vehicle exterior
●Working from top to bottom, liberally apply water to the vehicle body,
wheel wells and underside of the vehicle to remove any dirt and dust.
●Wash the vehicle body using a sponge or soft cloth, such as a chamois.
●For hard-to-remove marks, use car wash soap and rinse thoroughly
with water.
●Wipe away any water.
●Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle body is
cool.
■Self-restoring coat
The vehicle body has a self-restoring coating that is resistant to small surface
scratches caused in a car wash etc.
●The coating lasts for 5 to 8 years from when the vehicle is delivered from the plant.
●The restoration time differs depending on the depth of the scratch and outside
temperature. The restoration time may become shorter when the coating is
warmed by applying warm water.
●Deep scratches caused by keys, coins, etc. cannot be restored.
●Do not use wax that contain abrasives.
■Automatic car washes
●Fold the mirrors before washing the vehicle. Start washing from the front of the
vehicle. Make sure to extend the mirrors before driving.
●Brushes used in automatic car washes may scratch the vehicle surface and harm
your vehicle’s paint.
●Rear spoiler (if equipped) may not be washable in some automatic car washes.
There may also be an increased risk of damage to vehicle.
Perform the following to protect the vehicle and maintain it in prime
condition:

Maintenance and care
GS350_250_OM_OM30E16E_(EE)
■High-pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity of the win-
dows.
●Before using the car wash, check that the fuel filler door on your vehicle is closed
properly.
■Notes for a smart entry & start system
If the door handle becomes wet while the electronic key is within the effective range,
the door may lock and unlock repeatedly. In that case, follow the following correc-
tion procedures to wash the vehicle:
●Place the key in a position 2 m (6 ft.) or more separate from the vehicle while the
vehicle is being washed. (Take care to ensure that the key is not stolen.)
●Set the electronic key to battery-saving mode to disable the smart entry & start sys-
tem. (→P. 1 3 3 )
■Aluminum wheels
●Remove any dirt immediately by using a neutral detergent. Do not use hard
brushes or abrasive cleaners. Do not use strong or harsh chemical cleaners.
Use the same mild detergent and wax as used on the paint.
●Do not use detergent on the wheels when they are hot, for example after driving for
long distance in the hot weather.
●Wash detergent from the wheels immediately after use.
■Bumpers
Do not scrub with abrasive cleaners.
■Front side windows water-repellent coating
●The following precautions can extend the effectiveness of the water-repellent coat-
ing.
• Remove any dirt, etc. from the front side windows regularly.
• Do not allow dirt and dust to accumulate on the windows for a long period.
Clean the windows with a soft, damp cloth as soon as possible.
• Do not use wax or glass cleaners that contain abrasives when cleaning the win- dows.
• Do not use any metallic objects to remove condensation build up.
●When the water-repellent performance has become insufficient, the coating can
be repaired. Contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional.
