CAUTION
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as dangerous
handling characteristics, which may lead to an accident resulting in death or seri-
ous injury.
●Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other than those recommended by Lexus.
●Do not mix differently constructed tires (radial, bias-belted or bias-ply tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
●Vehicles with a compact spare tire: Do not tow if your vehicle has a compact
spare tire installed.
●Vehicles with an emergency tire puncture repair kit (if equipped): Do not tow
anything if a tire that has been repaired using the emergency tire puncture repair
kit is installed. The load on the tire may cause unexpected damage to the tire.
■When initializing the tire pressure warning system (vehicles with the tire pressure
warning system)
Do not operate the tire pressure warning reset switch without first adjusting the tire
inflation pressure to the specified level. Otherwise, the tire pressure warning light
may not come on even if the tire inflation pressure is low, or it may come on when
the tire inflation pressure is actually normal.

■While towing
If the engine is not running, the power assist for the brakes and steering will not func-
tion, making steering and braking more difficult.
■Wheel nut wrench
Wheel nut wrench is installed in trunk. (→P. 5 7 8 , 5 9 3 )
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When towing the vehicle
■While towing
●When towing using cables or chains, avoid sudden starts, etc. which place exces-
sive stress on the towing eyelet, cables or chains. The towing eyelet, cables or
chains may become damaged, broken debris may hit people and cause serious
damage.
●Do not turn the engine switch off.
There is a possibility that the steering wheel is locked and cannot be operated.
■Installing towing eyelet to the vehicle
Make sure that towing eyelet is installed securely.
If not securely installed, towing eyelet may come loose during towing.
2WD models:
Be sure to transport the vehicle with all four
wheels raised off the ground. If the vehicle is
towed with the tires contacting the ground,
the drivetrain and related parts may be dam-
aged or an accident may occur due to a
change in direction of the vehicle.
AW D m o d e l s :
Be sure to transport the vehicle with all four
wheels raised off the ground. If the vehicle is
towed with the tires contacting the ground,
the drivetrain or related parts may be dam-
aged, the vehicle may fly off the truck.

■Warning message in radar cruise mode (if equipped)
In the following cases, the warning message may not be displayed even if vehicle-to-
vehicle distance decreases:
●When your vehicle and the vehicle ahead are traveling at the same speed or the
vehicle ahead is traveling more quickly than your vehicle
●When the vehicle ahead is traveling at a very low speed
●Immediately after cruise control speed is set
●At the instant the accelerator pedal is depressed
■The LKA (Lane-Keeping Assist) lane departure warning function
In the following cases, the warning message will not be displayed even if a lane line is
crossed.
●When the vehicle speed deviates from the operating range of the LKA system
functions
●When the lane lines cannot be recognized
●When the steering wheel is turned as far as necessary to cause the vehicle to
change lanes
■Open door warning message
The open door warning message continues to display until a door or the trunk is fully
closed, even if the engine switch is turned off. However, approximately 20 minutes
after a door or the trunk is not fully closed, the battery-saving function operates and
the display turns off even though a door or the trunk is not fully closed.

■Stopping the engine
Shift the shift lever to P and press the engine switch as you normally do when stop-
ping the engine.
■Replacing the key battery
As the above procedure is a temporary measure, it is recommended that the elec-
tronic key battery be replaced immediately when the battery is depleted. (→P. 4 8 9 )
■Alarm (if equipped)
Using the mechanical key to lock the doors will not set the alarm system.
If a door is unlocked using the mechanical key when the alarm system is set, the
alarm may be triggered.

The engine does not start and modes will be changed each time the switch is
pressed.( →P. 2 3 8 )

●Make sure that the smart entry & start system has not been deactivated in the cus-
tomization setting. If it is off, turn the function on.
(Customizable features: →P. 6 5 0 )
●Check if battery-saving mode is set. If it is set, cancel the function. ( →P. 1 3 3 )

6227-2. Steps to take in an emergency
GS350_250_OM_OM30E16E_(EE)
Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that level for approximately 5 minutes to
recharge the battery of your vehicle.
Open and close any of the doors of your vehicle with the engine switch
off.
Maintain the engine speed of the second vehicle and start the engine of
your vehicle by turning the engine switch to IGNITION ON mode.
Once the vehicle’s engine has started, remove the jumper cables in the
exact reverse order from which they were connected.
Once the engine starts, have the vehicle inspected at any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional as soon as possible.
■Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■To prevent battery discharge
●Turn off the headlights and the audio system while the engine is off.
●Turn off any unnecessary electrical components when the vehicle is running at a
low speed for an extended period, such as in heavy traffic.
■Charging the battery
The electricity stored in the battery will discharge gradually even when the vehicle is
not in use, due to natural discharge and the draining effects of certain electrical
appliances. If the vehicle is left for a long time, the battery may discharge, and the
engine may be unable to start. (The battery recharges automatically during driving.)

■When recharging or replacing the battery
●For vehicles with an alarm: make sure that the key is not inside the vehicle when
recharging or replacing the battery. The key may be locked in the vehicle if the
alarm is activated. (→P. 88)
●In some cases, it may not be possible to unlock the doors using the smart entry &
start system when the battery is discharged. Use the wireless remote control or the
mechanical key to lock or unlock the doors.
●The engine may not start on the first attempt after the battery has recharged but
will start normally after the second attempt. This is not a malfunction.
●The engine switch mode is memorized by the vehicle. When the battery is recon-
nected, the system will return to the mode it was in before the battery was dis-
charged. Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.
CAUTION
■Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flammable
gas that may be emitted from the battery:
●Make sure each jumper cable is connected to the correct terminal and that it is
not unintentionally in contact with any other than the intended terminal.
●Do not allow the other end of the jumper cable connected to the “+” terminal to
come into contact with any other parts or metal surfaces in the area, such as
brackets or unpainted metal.
●Do not allow the + and - clamps of the jumper cables to come into contact with
each other.
●Do not smoke, use matches, cigarette lighters or allow open flame near the bat-
tery.
