At speeds between approximately 35 mph (60 km/h)
and 60 mph (95 km/h) the vehicle chassis is lowered to
its normal level.
At speeds above approximately 60 mph (95 km/h) the
vehicle chassis is lowered an additional one half inch
(15 mm).
Notes:
When exceeding approximately 35 mph (60 km/h), the
system will switch from option 2 to option 1. Only one
indicator lamp will be illuminated.
When exceeding approximately 60 mph (95 km/h) the
system will switch from option 1 to Normal Level. The
indicator lamp will go out.
If speed exce eds approx. 35 mph (60 km/h) bu t d oes not
exceed 60 mph (95 km/h), the system will switch from
option 2 to option 1 when vehicle speeds drop below
approximately 35 mph (60 km/h).
If speed does not exceed 35 mph (60 km/h), the system
will switch from option 2 to option 1 when driving on
after the vehicle has been stopped.Wheel change switch (2)
Prior to changing a wheel, depress wheel change switch
with engine running. The indicator lamp in the switch
and ADS malfunction indicator lamp light up. The
presently selected level option cannot be changed now.
After activating the wheel change switch turn off the
engine.
Wa r n i n g !
Do not drive the vehicle while the wheel change
switch is activated since the vehicle suspension
will not function properly.

See illustration for proper storage of jack.
Before storing t he ja ck, the ja ck arm (5) must be lowered
almost to the base (6) of the jack.
Note:
First remove the vehicle jack, then the spare wheel;
reinstall in reverse order.
Wa r n i n g !
The jack is designed exclusively for jacking up the
veh icle at th e jack tu bes bu ilt into eit her side of th e
vehicle. To help avoid personal injury, use the jack
only to lift the vehicle during a wheel change.
Never get beneath the vehicle while it is supported
by t he jack. Keep hands and feet away from th e area
under the lifted vehicle. Always firmly set parking
brake and block wheels before raising vehicle with
jack.Do not disengage parki ng brake wh ile th e vehi cle i s

when in use, especially on hills. Always try to use
the jack on level surface. Be sure that the jack arm
is fully inserted in the jack tube. Always lower the
vehicle onto sufficient capacity jackstands before
working under the vehicle.

(with Sport Package)
The spare wheel rim size is 8
1/4 J x 17 H2 with tire size
245/45 R 17 95W.
In the case of a f lat tire or breakdown, you may
temporarily use the spare wheel.
Unidirectional tires must always be mounted with arrow
on tire sidewall pointing in direction of vehicle forward
movement. If the arrow on tire sidewall does not point
in direction of vehicle forward movement when using
the spare wheel, observe the following restrictions:
• Do not exceed vehicle speed of 50 mph (80 km/h).
• Drive to the nearest repair facility to have the flat
tire repaired or replaced as appropriate.
• Do not operate vehicle with more than one spare
wheel mounted.
For additional information, refer to page 273.
Wa r n i n g !
The spare wheel rim is for temporary use only. Use
for over a total of 12 000 miles (20 000 km) may
cause wheel rim failure leading to an accident and
possible injuries. The dimensions of the spare wheel are different
from those of road wheels. As a result, the vehicle
handling characteristics change when driving with
a mounted spare wheel.The spare wheel should only be used temporarily,
and replaced with a regular road wheel as quickly
as possible.

Changing wheelsMove vehicle to a level area which is a safe distance
from the roadway.
1. Firmly set parking brake, raise roll bar, and turn on
hazard warning f lasher.
2. Move selector lever to position “P”.
3. While engine is running, depress wheel change
switch for level control. The indicator lamp in the

4. Turn off engine.
5. Prevent vehicle from rolling away by blocking
wheels with wheel chocks (not supplied with
vehicle) or sizable wood block or stone. When
changing a wheel on a hill, place chocks on the
downhill side blocking both wheels of the other
axl e. On a l evel road, pl ace one ch ock in front of a nd
one behind the wheel that is diagonally opposite to
the wheel being changed.

cover.
Before storing the jack, the jack arm must be
lowered almost to the base of the jack.
Store the spare wheel first and then the vehicle jack.
14. Using the wrench, tighten the five bolts evenly,
following the sequence illustrated, until all bolts are
tight.
Observe a tightening torque of 80 ft.lb. (110 Nm).
15. Ensure proper tire pressure.
16. Depress wheel change switch for level control. The
indicator lamp in the switch and the ADS
malfunction indicator lamp will go out.
Wa r n i n g !
Always replace wheel bolts that are damaged or
rusted.Never apply oil or grease to wheel bolts.Damaged wheel hub threads should be repaired
immediately.Incorrect mounting bolts or improperly tightened
mounting bolts can cause the wheel to come off.
This could cause an accident. Be sure to use the
correct mounting bolts.

Tire inflation pressure
A table (see fuel filler flap) lists the tire inflation
pressures specified for Mercedes-Benz recommended
tires as well as for the varying operating conditions.
Important!
Tire pressure changes by approx. 1.5 psi (0.1 bar) per
18°F (10°C) of air temperature change. Keep this in
mind when checking tire pressure inside a garage -
especially in the winter.
Example:
If garage temperature = approx. +68°F (+20°C) and
ambient temperature = approx. +32°F (0°C) then the
adjusted air pressure = specified air pressure +3psi
(+0.2 bar).
Tire pressures listed for light loads are minimum values
offering high driving comfort. Increased inflation
pressures for heavy loads produce favorable handling
characteristics with lighter loads and are perfectly
permissible. The ride of the vehicle, however, will
become somewhat harder.
Tire temperature and pressure increase with the vehicle
speed. Tire pressure should therefore only be checked
and corrected on cold tires. Correct tire pressure in
