may cause the charger to become hot and cause burns or could cause
electric shock resu lting in death or
serious injury.
■Cleaning the interior (especially
instrument panel)
Do not use a polish wax or polish
cleaner. The instrument panel may
reflect off the windshield, obstructing the driver’s view and leading to an
accident, resulting in death or serious
injury.
NOTICE

■Preventing damage to leather

Observe the following precautions to
avoid damage to and deterioration of

●Remove any dust or dirt from
leather surfaces immediately.
●Do not expose the vehicle to direct
sunlight for extended periods of
time. Park the vehicle in the shade, especially during summer.
●Do not place items made of vinyl, plastic, or containing wax on the
upholstery, as they may stick to the
leather surface if the vehicle interior heats up significantly.
■Water on the floor
Do not wash the vehicle floor with
water.
Vehicle systems such as the audio system may be damaged if water
comes into contact with electrical
components such as the audio sys - tem above or under the floor of the
