Hybrid battery (traction battery) ●
Never resell, hand over or modify the hybrid battery. To prevent accidents, hybrid
batteries that have been removed from a disposed vehicle are collected through
Lexus dealer. Do not dispose of the battery yourself.
Unless the battery is properly collected, th e following may occur, resulting in death
or serious injury:
• The hybrid battery may be illegally dispos ed of or dumped, and it is hazardous to
the environment or someone may touch a high voltage part, resulting in an electric
shock.
• The hybrid battery is intended to be used exclusively with your hybrid vehicle. If
the hybrid battery is used outside of your vehicle or modified in any way, accidents
such as electric shock, heat generation , smoke generation, an explosion and elec-
trolyte leakage may occur.
When reselling or handing over your ve hicle, the possibility of an accident is
extremely high because the person receiving the vehicle may not be aware of these
dangers. ●
If your vehicle is disposed of without the hybrid battery having been removed, there is
a danger of serious electric shock if high voltage parts, cables and their connectors
are touched. In the event that your vehicle must be disposed of, the hybrid battery
must be disposed of by your Lexus dealer or a qualified service sh op. If the hybrid bat-
tery is not disposed of properly, it may caus e electric shock that can result in death or
serious injury.
NOTICE ■

Do not place objects that will block the air intake vents. The hybrid battery (traction
battery) may have a reduction in hybrid batt ery (traction battery) output as well as be
damaged. ●
Clean the air intake and discharge vents regularly to prevent the hybrid battery (trac-
tion battery) from overheating. ●
Do not get water or foreign materials in either the air intake and discharge vents as
this may cause a short circuit and damage the hybrid battery (traction battery). ●
Do not carry large amounts of water such as water cooler bottles in the vehicle. If
water spills onto the hybrid battery (traction battery), the battery may be damaged.
