Aiming
Headlamp aim has been preset
and should need no further
adjustment.
If the vehicle is damaged in a
crash, the headlamp aim may
be affected. If adjustment to
the headlamps is necessary,
see your dealer.
Bulb Replacement
LED Lighting
This vehicle has LED lamps.
For replacement of any LED
lighting assembly, contact
your dealer.
Electrical System
Electrical System
Overload
The vehicle has fuses and
circuit breakers to protect
against an electrical system
overload.
When the current electrical
load is too heavy, the circuit
breaker opens and closes,
protecting the circuit until the
current load returns to normal
or the problem is fixed. This
greatly reduces the chance of
circuit overload and fire
caused by electrical problems.
