Maintenance
G. Tire Pressure
Maximum tire pressure recommendation for the CST tubeless
20 x 9.0-12 street tire is 40 psi max. Lied car terrain tire 23 x 10.5-12
is 20 psi max. Over-inflation or under-inflation will have a negative
eect on tire wear and even life of battery. It is recommended that
tire pressure is monitored regularly at least twice a year with seasonal
temperature changes.
H. Light Bulb Replacement
The Sirius comes equipped with a complete array of LED illumination.
LED (Light Emitting Diode) systems use less power, provide greater
reliability under many dierent conditions, and are not eected by
vibration and impact. LED bulbs also have a much longer lifespan so
replacement is not needed. However in the event that failure occurs
with secondary LED illumination (Parking, Turn, Brake, Reverse) it is
more common for a single LED to fail, rather than the entire array. In
this case, a replacement assembly can be swapped by an authorized
service dealer. Access to the assembly fasteners can be found in each
wheel well and tail light assembly fasteners are located behind the
rear wheel well splash shield.
1. Headlight Bulb Replacement
It is recommended that an authorized technician change expended
bulbs, but if you have personally changed automobile headlight bulbs,
the Sirius will be no dierent. In the rare event that the headlight
bulbs need to be replaced, there is a convenient rubber cap in each
glove box cavity that, if removed, will provide access to the back of the
headlight assembly.
