Maintenance and care
CAUTION

Replacing light bulbs
● Be sure to stop the hybrid system and turn off the lights. Do not attempt to
replace the bulb immediately after turning off the lights.
The bulbs become very hot and may cause burns.
● Do not touch the glass portion of the light bulb with bare hands. Hold the
bulb by the plastic or metal portion.
If the bulb is scratched or dropped, it may blow out or crack.
● Fully install light bulbs and any parts used to secure them. Failure to do so
may result in heat damage, fire, or water entering the headlight unit. This
may damage the headlights or cause condensation to build up on the lens.
■ To prevent damage or fire
Make sure bulbs are fully seated and locked.

■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure

ent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the
