Your vehicle automatically adjusts its ride
height to
increase vehicle safety

The following vehicle chassis ride heights
can be selected:

The vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed:
At a speed exceeding approximately
68 mph (110 km / h) with normal level
set or exceeding 75 mph (120 km / h)
with raised level set, the ride height is
reduced automatically. The table on
the next page provides an overview of
the vehicle levels.
With decreasing speed, the ride height
is again raised to the normal level.
Select the raised level only when required
by current driving conditions. Otherwise
handling may be impaired
fuel consumption may increase
!If you have selected the Comfort sus-
pension tuning (
page 238), the vehi-
cle lowers slightly when you lock it
within approximately 60 seconds after
switching off the engine. When parking,
make sure that your vehicle cannot
come into contact with other objects,
such as a curb, while lowering. Your ve-
hicle could otherwise be damaged.
iThe selected suspension style is stored
in memory, even after the SmartKey is
removed from the starter switch.
iThese height adjustments are so small
that you may not notice any change.Warning!
