2018 TOYOTA HIGHLANDER HYBRID battery

SAFETY PRECAUTIONS
Your Highlander Hybrid has both high-voltage DC and AC systems as well as a 12-volt system.
Both DC and AC high voltage are very dangerous and can cause personal injury, severe burns,
electric shock and even fatal injury.
To avoid personal injury, please follow all caution labels attached to high-voltage parts. Do not
touch or attempt to remove or replace any high-voltage (orange-colored) wiring and connectors.
Do not touch the service plug, which is on the driver’s side of the vehicle under the carpeted
ap on the oor next to the second-row bench seat.
If an accident occurs, do not touch any high-voltage wiring, connectors or parts such as the
inverter unit or hybrid vehicle battery assembly.
Do not touch the potassium hydroxide electrolyte that might spill or leak from the hybrid vehicle
battery as the result of an accident. If potassium hydroxide electrolyte gets on your skin or in
your eyes, neutralize it immediately with a saturated boric acid solution (ratio: 80 grams boric
acid to two liters water). Seek immediate medical attention.
If a vehicle re occurs, extinguish it with a Class D powder-type re extinguisher.
Toyota recommends having maintenance and repairs for your Highlander Hybrid
performed by an authorized Toyota dealership. To locate your nearest authorized
Toyota dealership, contact the Toyota Customer Experience Center at (800) 331-4331
or log on to www.toyota.com.

MAINTENANCE
You are responsible for performance of
the required maintenance indicated in the
Owner’s Manualand this booklet. Toyota
will not deny a warranty claim solely
because you do not have records to show
that you maintained your vehicle. However,
any failure or noncompliance caused by
lack of maintenance is not covered by this
warranty.
When maintenance and repairs are paid
for by you, these services may be
performed by you or by any automotive
service provider you choose. Toyota will
not deny a warranty claim solely
because you used a service provider
other than a Toyota dealership for
maintenance and repairs. However, any
failure or noncompliance caused by
improper maintenance or repairs is not
covered by this warranty.
