AIR BODY CONTROL
General notes
AIR BODY CONTROL is an air suspension systemwith variable damping for improved driving com-fort. All-round level control ensures the bestpossible suspension and constant ground clear-ance, even with a laden vehicle. When you drivefast, the vehicle is lowered automatically toimprove driving safety and to reduce fuel con-sumption. There is also the option to manuallyadjust the vehicle level.
AIR BODY CONTROL consists of:
Rair suspension system with variable springrate
Rautomatic level control
Rspeed-dependent lowering to reduce fuelconsumption
Rmanual level control
RADS PLUS (Adaptive Damping System withcontinuous damping adjustment)
RDYNAMIC SELECT switch (Ypage 139) andlevel button (Ypage 173)

GWARNING
A flat tire severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is a risk of accident.
Tires without run-flat characteristics:
Rdo not drive with a flat tire.
Rimmediately replace the flat tire with your
emergency spare wheel or spare wheel, or
consult a qualified specialist workshop.
Tires with run-flat characteristics:
Rpay attention to the information and warn-

Accessories that are not approved for your vehi-cle by Mercedes-Benz or are not being used cor-rectly can impair the operating safety.
Before purchasing and using non-approvedaccessories, visit a qualified specialist work-shop and inquire about:
Rsuitability
Rlegal stipulations
Rfactory recommendations
Further information regarding wheels and tirescan be found under "Wheel/tire combinations"(Ypage 354).
You can ask for information regarding permittedwheel-tire combinations at an authorizedMercedes-Benz Center.
Information on tire pressure can be found:
Ron the Tire and Loading Information placardon the B-pillar on the driver's side(Ypage 340)
Rin the tire pressure table in the fuel filler flap(Ypage 333)
Runder "Tire pressure" (Ypage 333)
Operation
Information on driving
Check the tire pressure when the vehicle isheavily laden and adjust prior to a trip.
While driving, pay attention to vibrations, noisesand unusual handling characteristics, e.g. pull-ing to one side. This may indicate that thewheels or tires are damaged. If you suspect thata tire is defective, reduce your speed immedi-ately. Stop the vehicle as soon as possible tocheck the wheels and tires for damage. Hiddentire damage could also be causing the unusualhandling characteristics. If you find no signs ofdamage, have the tires and wheels checked at aqualified specialist workshop.
When parking your vehicle, make sure that thetires do not get deformed by the curb or otherobstacles. If they cannot be avoided, drive overobstacles such as curbs slowly and at an obtuseangle. Otherwise, you may damage the wheelsor tires.
Regular checking of wheels and tires
