7-2. Steps to take in an emergency
When trouble arises
■
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 entry &
start system when the battery is dis-
charged. 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 bat-
tery, 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.
■
When replacing the battery
●
Use a battery that conforms to European
regulations.
●
Use a battery that tha case size is same as
the previous one (LN3), 20 hour rate
capacity (20HR) is equivalent (70Ah) or
greater, and performance rating (CCA)
is equivalent (592A) 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, battery may dis-
charge and the engine may not be able to
start.
●
For details, consult your Lexus dealer.
■
Avoiding battery fires or explosions
Observe the following precautions to
prevent accidentally igniting the flamma-
ble gas that may be emitted from the bat-
tery:
●
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 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
battery.
●
If the battery fluid level is excessively
low (P.322), do not use the battery.
■
Battery precautions
The battery contains poisonous and cor-
rosive acidic electrolyte, while related
parts contain lead and lead compounds.
Observe the following precautions when
handling the battery:
●
When working with the battery, always
wear safety glasses and take care not
to allow any battery fluids (acid) to
come into contact with skin, clothing
or the vehicle body.
●
Do not lean over the battery.
●
In the event that battery fluid comes
into contact with the skin or eyes,
immediately wash the affected area
with water and seek medical attention.
Place a wet sponge or cloth over the
affected area until medical attention
can be received.
