FRONT SUSPENSION
The front suspension is MacPherson strut type with
coil springs and compression rod. Anti-dive geometry
ensures excellent driving stability while negative off-
set geometry provides good braking stability. The off-
set coil spring ensures optimum riding comfort.

If the front suspension is faulty, the vehicle will not
run straightforward or noise will occur. Incorrect
wheel alignment, malfunction of strut assembly, sta-
bilizer bar, coil spring, or worn or out-of-balance tires
can cause these problems.
