Prior to operating the vehicle, the driver 
should check and adjust the seat height, 
seat position fore and aft, and seat back-
rest angle if necessary, to ensure adequate 
control, reach and comfort. The head re-
straint should also be adjusted for proper 
height. See also the section on air bags 
(page 65) for more information on prop-
er seat positioning.
In addition, adjust the steering wheel to 
ensure adequate control, reach, operation 
and comfort. Both the interior and exterior 
rear view mirrors should be adjusted for 
adequate rear vision.
Fasten seat belts. Infants and small chil-
dren should be seated in a properly se-
cured restraint system that complies with 
U.S. Federal Motor Vehicle Safety Stan-
dards 213 and 225 and Canadian Motor 
Vehicle Safety Standards 213 and 210.2.With the memory function you can store up 
to three different settings.

Press the damping button1 until the 
desired suspension style is set.Vehicle level control
Your vehicle automatically adjusts its ride 
height to
increase vehicle safety
reduce fuel consumption
The following vehicle chassis ride heights 
can be selected:
Normal
Raised
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!
