connect a negative cable clamp to   on the second vehicle and connect the 
clamp at the other end of the negative cable to  .
Exclusive jump starting terminal (your vehicle)
Positive (+) battery terminal (second vehicle)
Negative (-) battery terminal (second vehicle)
Solid, stationary, unpainted metallic point away from the exclusive jump starting 
terminal and any mo ving parts as shown in the illustration
7 Start the engine of the second vehi-
cle. Increase the engine speed 
slightly and maintain at that level for 
approximately 5 minutes to 
recharge the battery of your vehi-
cle.
8 Open and close any of the doors of 
your vehicle with the engine switch 
off.
9 Maintain the engine speed of the 
second vehicle and start the engine 
of your vehicle by turning the 
engine switch to IGNITION ON 
mode.
10 Once the vehicle’s engine has 
started, remove the jumper cables 
in the exact reverse order from 
which they were connected. 11
Close the exclusive jump starting 
terminal cover, and reinstall the fuse 
box cover to its original position.
12 Install the service cover. ( P.379)
13 Install the engine cover. ( P.379)
Once the engine starts, have the vehi-
cle inspected at your Lexus dealer as 
soon as possible.
■Starting the engine when the battery is 
discharged
The engine cannot be  started by push-start-
ing.
■To prevent battery discharge
●Turn off the headlights and the audio sys-
tem while the engine is off.
●Turn off any unnecessary electrical com-
ponents when the vehicle is running at a 
low speed for an extended period, such

■When the battery is removed or dis-
charged
●Information stored in the ECU is cleared. 
When the battery is depleted, have the 
vehicle inspected at your Lexus dealer.
●Some systems may require initialization. 
( P.484)
■When removing the battery terminals
When the battery terminals are removed, 
the information stored in the ECU is 
cleared. Before removi ng the battery termi-
nals, contact your Lexus dealer.
■Charging the battery
The electricity stored in the battery will dis-
charge gradually even when the vehicle is 
not in use, due to natural discharge and the 
draining effects of certain electrical appli-
ances. 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 bat-
tery
●In some cases, it may not be possible to 
unlock the doors using the smart access 
system with push-button start 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 di sconnecting the bat-
tery, turn the engine switch off.
If you are unsure what mode the engine 
switch was in befo re the battery dis-
charged, be especially careful when 
reconnecting the battery.
■When replacing the battery
●Use a Central Degassing type battery 
(European Regulations).
●Use a battery with the same case size as  the previous battery and an equivalent 
20 hour rate capacity (20HR) or greater.
• If the sizes differ, the battery cannot be 
properly secured.
• If the 20 hour rate capacity is low, even if  the time period where the vehicle is not 
used is a short time, the battery may dis-
charge and the engine may not be able to 
start.
●Use a battery with a handle. If a battery 
without a handle is used, removal is more 
difficult.
●After replacing, firm ly attach the follow-
ing items to the exhaust hole of the bat-
tery.
• Use the exhaust hose that was attached 
to the battery before replacing and con-
firm that it is firmly connected to the hole 
section of the vehicle.
• Use the exhaust hole plug included with  the battery replaced or the one installed 
on the battery prior to the replacement. 
(Depending on the battery to be 
replaced, the exhaust hole may be 
plugged.)

■Engine oil selection
“Toyota Genuine Motor Oil” is used in 
your Lexus vehicle. Use Lexus 
approved “Toyota Genuine Motor Oil” 
or equivalent to satisfy the following 
grade and viscosity.
Oil grade: ILSAC GF-5 multigrade 
engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for 
good fuel economy and good starting 
in cold weather.
If SAE 0W-20 is not available, SAE 
5W-20 oil may be used. However, it 
must be replaced with SAE 0W-20 at  the next oil change.
Recommended viscosity (SAE):
Outside temperature
Oil viscosity (0W-20 is explained here 
as an example):
• The 0W in 0W-20 indicates the  characteristic of the oil which allows 
cold startability. Oils with a lower 
value before the W allow for easier 
starting of the engine in cold 
weather.
• The 20 in 0W-20 indicates the vis- cosity characteristic of the oil when 
the oil is at high temperature. An oil 
with a higher viscosity (one with a 
higher value) may be better suited if 
the vehicle is operated at high 
speeds, or under extreme load con-
ditions.
