Safety guidelines for the seat belt, emergency 
tensioning retractor and airbag
Wa r n i n g !
If you believe that, even with the use of these 
guidelines, it would be safer for your rear seat 
occupants to have both rear door mounted side 
airbags deactivated, then deactivation can be 
accomplished upon your written election to do so at 
your authorized Mercedes-Benz Center at an 
additional cost. Please contact your local 
authorized Mercedes-Benz Center or call our 
Customer Assistance Center at 1-800-FOR-
MERCedes (1-800-367-6372) for details.
Wa r n i n g ! • Damaged seat belts or belts that were highly  stressed in an accident must be replaced and 
their anchoring points must also be checked. 
Use only belts installed or supplied by an 
authorized Mercedes-Benz Center.• Airbags and “ETR’s” are designed to function on a one-time-only basis. An airbag or 
emergency tensioning retractor (ETR) that was 
activated must be replaced.• No modifications of any kind may be made to any components or wiring of the “SRS”. This 
includes changing or removing any component 
or part of the “SRS”, the installation of 
additional trim material, badges etc. over the 
steering wheel hub, front passenger airbag 
cover, door trim panels, or door frame trims, 
and installation of additional electrical /
electronic equipment on or near “SRS” 
components and wiring. Keep area between 
airbags and occupants free from objects (e.g. 
packages, purses, umbrellas, etc).

Wheels
Replace rims or tires with the same designation, 
manufacturer and type as shown on the original part. 
See your authorized Mercedes-Benz Center for further 
information.
See your authorized Mercedes-Benz Center for 
information on tested and recommended rims and tires 
for summer and winter operation. They can also offer 
advice concerning tire service and purchase.
Tire replacement
Front and rear tires should be replaced in sets. Rims 
and tires must be of the correct size and type. For 
dimensions, see “Technical Data”.
We recommend that you break in new tires for 
approximately 60 miles (100 km) at moderate speed.
Wa r n i n g !
The jack is designed exclusively for jacking up the 
vehicle at the jack take-up brackets built into either 
side of the 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 the jack. Keep hands and feet away 
from the area under the lifted vehicle. Always 
firmly set parking brake and block wheels before 
raising vehicle with jack.Do not disengage parking brake while the vehicle is 
raised. Be certain that the jack is always vertical 
when in use, especially on hills. Always try to use 
the jack on level surface. Be sure that the jack arm 
is fully seated in the jack take-up bracket. Always 
lower the vehicle onto sufficient capacity 
jackstands before working under the vehicle.

It is imperative that the wheel mounting bolts be 
fastened to a tightening torque of 80 ft.lb. (110 Nm) 
whenever wheels are mounted.
For rim and tire specifications, refer to “Technical Data”.
Rotating wheels
The wheels can be rotated according to the degree of 
tire wear while retaining the same direction of travel.
Rotating, however, should be carried out as 
recommended by the tire manufacturer, before the 
characteristic tire wear pattern (shoulder wear on front 
wheels and tread center wear on rear wheels) becomes 
visible, as otherwise the driving properties deteriorate.
Notes:
Thoroughly clean the inner side of the wheels any time 
you rotate the wheels or wash the vehicle underside.
The use of retread tires is not recommended. Retread 
tires may adversely affect the handling characteristics 
and safety of the vehicle.
Dented or bent rims can cause tire pressure loss and 
damage to the tire beads. For this reason, check rims for 
damage at regular intervals. The rim flanges must be 
checked for wear before a tire is mounted. Remove 
burrs, if any.
Check and ensure proper tire inflation pressure after 
rotating the wheels. For tire inflation pressure see 
inside of fuel filler flap and also page 278.
Wa r n i n g !
Worn, old tires can cause accidents. If the tire tread 
is badly worn, or if the tires have sustained 
damage, replace them.When replacing rims, use only genuine 
Mercedes-Benz wheel bolts specified for the 
particular rim type. Failure to do so can result in 
the bolts loosening and possibly an accident.

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.
