7
When trouble arises
turning the engine switch 
8 Once the vehicle’s engine 
jumper cables in the exact reverse 
order from which they were con-
nected.
9 Close the exclusive jump starting 
terminal cover, and reinstall the fuse 
box cover to its original position.
Once the engine 
have the vehicle inspected at your Lexus 
dealer as soon as possible.
■Starting the engine 
when the 12-volt battery is discharged
The engine 
started by push-starting.
■To prevent 12-volt battery discharge
●Turn off the headlights and the audio sys-
tem while the engine 
stopped.
●Turn off any unnecessary electrical com-
ponents when the vehicle is running at a 
low speed for an extended period, such 
as in heavy traffic.
■When the 12-volt battery is removed or 
discharged
●Information stored in the ECU is cleared. 
When the 12-volt battery is depleted, 
have the vehicle inspected at your Lexus 
dealer.
●Some systems may require initialization. 
(  P.407)
■When removing the 12-volt battery ter-
minals
When the 12-volt battery terminals are 
removed, the information stored in the 
ECU is cleared. Before removing the 12-
volt battery terminals, contact your Lexus 
dealer.
■Charging the 12-volt battery
The electricity stored in the 12-volt battery 
will discharge gradually even when the 
vehicle is not in use, due to natural dis-
charge and the draining effects of certain 
electrical appliances. If the vehicle is left for 
a long time, the 12-volt battery may dis-
charge, and the engine 
may be unable to start. (The 12-volt battery 
recharges automatically during driving.)
■When recharging or replacing the 12-
volt battery
●In some cases, it may not be possible to 
unlock the doors using the smart access 
system with push-button start when the 
12-volt battery is discharged. Use the 
wireless remote control or the mechani-
cal key to lock or unlock the doors.
●The engine 
on the first attempt after the 12-volt bat-
tery has recharged but will start normally 
after the second attempt. This is not a 
malfunction.
●The engine switch 
is memorized by the vehicle. When the 
12-volt battery is reconnected, the system 
will return to the mode it was in before 
the 12-volt battery was discharged. 
Before disconnecting the 12-volt battery, 
turn the engine switch 
If you are unsure wh at mode the engine 
switch 
12-volt battery discharged, be especially 
careful when reconnecting the 12-volt 
battery.
●If the 12-volt battery discharges, it may 
not be possible to shift the shift position to 
other positions. In this case, the vehicle 
cannot be towed without lifting both rear 
wheels because the re ar wheels will be 
locked. ( P.334)
■When replacing the 12-volt battery
●Use a Central Degassing type 12-volt 
battery (European Regulations).
●Type A*1: Use a 12-volt battery that the 
case size is same  as the previous one 
(LN4), 20 hour rate capacity (20HR) is 
equivalent (80Ah) or greater, and per-
formance rating (CCA) is equivalent 
(685A) or greater.  

3667-2. Steps to take in an emergency
Type B*2: Use a 12-volt battery that the 
case size is same as the previous one 
(LN3), 20 hour rate capacity (20HR) is 
equivalent (70Ah) or greater, and perfor-
mance rating (CCA) is equivalent 
(600A) or greater.
• If the sizes differ, the 12-volt battery can-
not 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 12-volt battery 
may discharge and engine 
●Use a 12-volt battery with a handle. If a 
12-volt battery without a handle is used, 
removal is more difficult.
●After exchanging, firmly attach the fol-
lowing items to the exhaust hole of the 12-
volt battery.
• Use the exhaust hose that was attached 
to the 12-volt battery before exchanging.
• Use the exhaust hole plug included with  the 12-volt battery exchanged or the one 
installed on the battery prior to the 
exchange. (Depending on the 12-volt 
battery to be exchanged, the exhaust 
hole may be plugged.)

WARNING
■When removing the 12-volt battery 
terminals
Always remove the negative (-) terminal 
first. If the positive (+) terminal contacts 
any metal in the surrounding area when 
the positive (+) terminal is removed, a 
spark may occur, leading to a fire in addi-
tion to electrical shocks and death or 
serious injury.
■Avoiding 12-volt battery fires or 
explosions
Observe the following precautions to 
prevent accidentally igniting the flamma-
ble gas that may be emitted from the 12-
volt battery:
●Make sure each jumper cable is con-
nected 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 “+” ter-
minal to come into contact with any 
other parts or meta l 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 
12-volt battery.
●If the 12-volt battery  fluid level is exces-
sively low ( P.305), do not use the 
12-volt battery.

■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 5W-30 SAE 5W-30 is the best choice for 
good fuel economy and good starting 
in cold weather.
If SAE 5W-30 is not available, SAE 
10W-30 oil may be used. However, it 
should be replaced with SAE 5W-30 
at the next oil change.
Outside temperature
Oil viscosity (5W-30 is explained here 
as an example):
• The 5W in 5W-30 indicates the  characteristic of the oil which allows
