■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
●If the battery becomes low, an alarm will sound in the cabin when the engine
stops. (P. 3 6 )
●As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indicate
that the electronic key battery may be depleted. Replace the battery when nec-
essary. ( P. 6 5 2 )
• The smart access system with push-bu tton start or the wireless remote con-
trol 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
•Glass top ranges

When driving
GX460_OM_OM60J63U_(U)●
Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before making a
turn.
● Note that when making a turn, the tr ailer wheels will be closer than the
vehicle wheels to the inside of th e turn. Compensate by making a
wider than normal turning radius.
● Slow down before making a turn, in crosswinds, on wet or slippery sur-
faces, etc.
Increasing vehicle speed can destabilize the trailer.
● Take care when passing other vehi cles. Passing requires considerable
distance. After passing a vehicle, do not forget the length of your
trailer, and be sure you have plenty of room before changing lanes.
● To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not put the transmission in D.
Transmission shift range position must be in 5 in the S mode.
● Instability happens more frequently when descending steep or long
downhill grades. Before descending, slow down and downshift. Do not
make sudden downshifts while descending steep or long downhill
grades.
● Avoid holding the brake pedal down too long or applying the brakes
too frequently. This could cause th e brakes to overheat and result in
reduced braking efficiency.
● Due to the added load of the trailer, your vehicle’s engine may overheat
on hot days (at temperatures over 85°F [30°C]) when driving up a
long or steep grade. If the eng ine coolant temperature gauge indicates
overheating, immediately turn off th e air conditioning (if in use), pull
your vehicle off the road and stop in a safe spot. ( P. 74 9 )

■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following before recharging:
●If recharging with the battery installed on the vehicle, be sure to disconnect the
ground cable.
●Make sure the power switch on the charger is off when connecting and discon-
necting the charger cables to the battery.
■After recharging/reconnecting the battery
●Unlocking the doors using the smart key system may not be possible immedi-
ately after reconnecting the battery. If this happens, use the wireless remote
control or the mechanical key to lock/unlock the doors.
●Start the engine with the “ENGINE START STOP” switch in ACCESSORY
mode. The engine may not start wi th the “ENGINE START STOP” switch
turned OFF. However, the engine will operate normally from the second
attempt.
●The “ENGINE START STOP” switch mode is recorded by the vehicle. If the bat-
tery is reconnected, the vehicle will return the “ENGINE START STOP” switch
mode to the status it was in before the battery was disconnected. Make sure to
turn off the engine before disconnect the battery. Take extra care when con-
necting the battery if the “ENGINE START STOP” switch mode prior to dis-
charge is unknown.
If the system will not start even after mult iple attempts, contact your Lexus dealer.

GX460_OM_OM60J63U_(U)
■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, etc.
■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 batt ery recharges automatically during driving.)
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 START STOP” switch off.
Maintain the engine speed of the second vehicle and start the
engine of your vehicle by tu rning the “ENGINE START STOP”
switch to IGNITION ON mode.
Once your vehicle’s engine has started, remove the jumper
cables in the exact reverse ord er in which they were con-
nected.
Once the engine starts, have the ve hicle checked at your Lexus dealer
as soon as possible.STEP3
