Rear torsion springs
WARNING
EWS00750
The left and right spring preloads must be
adjusted to the same setting. Uneven set-
tings can cause poor handling and loss of
stability.
To increase the spring preload and thereby
harden the suspension, turn the adjuster in di-
rection (a). To decrease the spring preload
and thereby soften the suspension, turn the
adjuster in direction (b).
