●The card key is not waterproof.
■When required to leave the vehicle’s key with a parking attendant
Lock the glove box as circumstances demand. (
P. 4 2 3 )
Remove the mechanical key for your own use and provide the attendant with the elec-
tronic key only.
■If you lose your mechanical keys
New genuine mechanical keys can be made by your Lexus dealer using another
mechanical key and the key number stamped on your key number plate. Keep the plate
in a safe place such as your wallet, not in the vehicle.
■When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press any but-
tons on the electronic key while inside the airc raft cabin. If you are carrying an electronic
key in your bag etc., ensure that the buttons are not likely to be pressed accidentally.
Pressing a button may cause the electronic key to emit radio waves that could interfere
with the operation of the aircraft.
■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.)
●If the battery becomes low, an alarm will sound in the cabin when the engine stops.
●As the electronic key always receives ra dio waves, the battery will become depleted
even if the electronic key is not used. The following symptoms indicate that the elec-
tronic key battery may be depleted. Replace the battery when necessary. ( P. 5 0 3 )
• The smart access system with push-button start or the wireless remote control does
not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
●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
• Table lamps
• Induction cookers
●If the battery cover is not installed and the bat-
tery falls out or if the battery was removed
because the key got wet, reinstall the battery
with the positive terminal facing the Lexus
emblem.

NOTICE
■Handling the card keys
●Do not apply excess force when inserting the mechanical key to the card key.
Doing so may damage the card key.
●If the battery or card key terminals get wet, the battery may corrode and the card key
may stop working.
If the key is dropped into water, or if drin
king water etc. is spilled on the key, immedi-
ately remove the battery cover and wipe the battery and terminals.
(To remove the battery cover, lightly grasp it and pull.) If the battery is corroded, have
your Lexus dealer replace the battery.
●Do not crush the battery cover or use a screwdriver to remove the battery cover.
Forcibly removing the battery cover may bend or damage the key.
●If the battery cover is frequently removed, the cover may become loose.
●When installing the battery, make sure to check the direction of the battery.
Installing the battery in the wrong direction may cause the battery to deplete rapidly.
●The surface of the card key may be damaged, or its coating may peel off in the follow-
ing situations:
• The card key is carried together with hard objects, such as coins or keys.
• The card key is scraped with a sharp obje ct, such as a tip of mechanical pencil.
• The surface of the card key is wiped with thinners or benzene.
■Carrying the electronic key on your person
Carry the electronic key 3.9 in. (10 cm) or mo re away from electric appliances that are
turned on. Radio waves emitted from electric appliances within 3.9 in. (10 cm) of the
electronic key may interfere with the key, causing the key to not function properly.
■In case of a smart access system with push-button start malfunction or other key-
related problems
Take your vehicle with all the electronic keys provided with your vehicle, including the
card key, to your Lexus dealer.
■When an electronic key is lost
If the electronic key remains lost, the risk of vehicle theft increases significantly. Visit
your Lexus dealer immediately with all rema ining electronic keys and the card key that
were provided with your vehicle.

■Battery-saving function
The battery-saving function will be activated
in order to prevent the electronic key bat-
tery and the battery from being discharged wh ile the vehicle is not in operation for a long
time.
●In the following situations, the smart access system with push-button start may take
some time to unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m) of the outside
of the vehicle for 10 minutes or longer.
• The smart access system with push-butto n start has not been used for 5 days or
longer.
●If the smart access system with push-butto n start has not been used for 14 days or
longer, the doors cannot be unlocked at any doors except the driver’s door. In this case,
take hold of the driver’s door handle, or us e the wireless remote control or the mechan-
ical key, to unlock the doors.
■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.
The smart access system with push-button start uses weak radio waves. In the following
situations, the communication between th e electronic key and the vehicle may be
affected, preventing the smart access system with push-button start, wireless remote
control and engine immobilizer system from operating properly.
(Ways of coping: P. 5 5 0 )
●When the electronic key battery is depleted
●Near a TV tower, electric powe r plant, gas station, radio station, large display, airport or
other facility that generates strong radio waves or electrical noise

LX570_OM_OM60N01U_(U)4-5. Using the driving support systems
This mode employs a radar sensor to detect the presence of vehicles up to
approximately 400 ft. (120 m) ahead, determines the current vehicle-to-vehicle
following distance, and operates to main
tain a suitable following distance from
the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long downhill
slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-vehicle dis-
tance can also be set by operating th e vehicle-to-vehicle distance button.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears
When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the system
applies the brakes (the stop lights will come on at this time). The system will respond to
changes in the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle
distance set by the driver. Approach wa rning warns you when the system cannot
decelerate sufficiently to prevent your ve hicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your ve hicle will also stop (vehicle is stopped by
system control). After the vehicle ahead starts off, pushing the cruise control lever up
or depressing the accelerator peda l will resume follow-up cruising.
Example of acceleration
When there are no longer any preceding vehicles driving slower than the set
speed
The system accelerates until the set speed is reached. The system then returns to con-
stant speed cruising.

spond to a vehicle speed of 50 mph (8 0 km/h). Vehicle-to-vehicle distance
increases/decreases in accordance with vehicle speed. When the vehicle is
stopped by system control, the vehicle- to-vehicle distance will be about 16 ft.
(5 m) to 23 ft. (7 m) regardless of the vehicle-to-vehicle distance setting.
After the vehicle ahead of you starts off,
push the lever up.
Your vehicle will also resume follow-up
cruising if the accelerator pedal is
