œ

The fuel tank is located under the floor of the rear 
seats to provide increased protection and a more 
luggage space.

œ

A fuel tank safety valve assembly has been 
adopted to prevent fuel from leaking out in case 
of a collision.

œ

A fuel pump assembly <2WD>, fuel pump and 
gauge assembly <4WD> including fuel pump, fuel 
filter, reservoir and fuel gauge unit, has been 
adopted to lighten weight and improve servicea-
bility.
