Automatic transmission*
Gear ranges
With the gear selector lever in drive 
positionD and driving in program modeC 
orS, you can select a gear range for the 
automatic transmission to operate within.
Gear selector lever (
page 162):
You can limit the gear range by pressing 
the gear selector lever to the left (D-), and 
reverse the gear range limit by pressing 
the gear selector lever to the right (D+).
Steering wheel gearshift control* 
(
page 163):
You can limit the gear range by pulling the 
left gearshift paddle on the steering wheel 
gearshift control, and reverse the gear 
range limit by pulling the right gearshift 
paddle on the steering wheel gearshift 
control.The selected gear range appears in the 
multifunction display.

Hydroplaning
Depending on the depth of the water layer 
on the road, hydroplaning may occur, even 
at low speeds and with new tires. Reduce 
vehicle speed, avoid track grooves in the 
road and apply brakes cautiously in the 
rain.
Tire traction
The safe speed on a wet, snow-covered or 
icy road is always lower than on a dry road.
You should pay particular attention to the 
condition of the road whenever the outside 
temperatures are close to the freezing 
point.Mercedes-Benz recommends winter tires 
(
page 332) with a minimum tread depth 
of approximately 1/6 in (4 mm) on all four 
wheels for the winter season to ensure 
normal balanced handling characteristics. 
On packed snow, they can reduce your 
stopping distance as compared with sum-
mer tires.
Stopping distance, however, is still consid-
erably greater than when the road is not 
covered with snow or ice. Exercise appro-
priate caution.
Warning!G
Do not drive with a flat tire. A flat tire affects 
the ability to steer or brake the vehicle. You 
may lose control of the vehicle. Continued 
driving with a flat tire or driving at high 
speed with a flat tire will cause excessive 
heat build-up and possibly a fire.
Warning!G
If ice has formed on the road, tire traction 
will be substantially reduced. Under such 
weather conditions, drive, steer and brake 
with extreme caution.
!Avoid spinning of a drive wheel. This may 
cause serious damage to the drivetrain which is 
not covered by the Mercedes-Benz Limited 
Warranty.

316 Operation
Tires and wheels
Reactivating the Run Flat Indicator
The tire inflation pressure monitor must be 
restarted in the following situations:
If you have changed the tire inflation 
pressure
If you have replaced the wheels or tires
If you have installed new wheels or 
tires
Using the Tire and Loading Information 
placard on the driver’s door B-pillar or, 
if available, the tire inflation pressure 
label on the inside of the fuel filler flap, 
make sure the tire inflation pressure of 
all four tires is correct.
Switch on the ignition (page 37).
The standard display menu appears in 
the multifunction display (
page 127).
Press buttonk orj repeatedly 
until the following message appears in 
the multifunction display:
Run Flat Indicator
active
Menu: R-Button
Press reset buttonJ (page 26).
The following message will appear in 
the multifunction display:
Restart 
Run Flat Indicator? If you wish to confirm activation:
Press buttonæ.
The following message will appear in 
the multifunction display:
Run Flat Indicator
restarted
After a certain “learning phase”, the Run 
Flat Indicator checks the set pressure val-
ues for all four tires.
If you wish to cancel activation:
Press buttonç.
or
Wait until the message
Restart 
Run Flat Indicator? 
disappears.Warning!G
The Run Flat Indicator can only warn you in 
a reliable manner if you have set the correct 
tire inflation pressures for each tire.
If an incorrect tire inflation pressure was 
set, the system will monitor the pressure 
according to the incorrect value.

434 Technical data
Rims and tires
!Only use tires which have been tested and 
approved by Mercedes-Benz. Tires approved by 
Mercedes-Benz are developed to provide best 
possible performance in conjunction with the 
driving safety systems on your vehicle such as 
ABS or ESP
®. Tires specially developed for your 
vehicle and tested and approved by 
Mercedes-Benz can be identified by finding the 
following on the tire’s sidewall:
MO = Mercedes-Benz Original equipment 
tires
AMG vehicles:
Does not apply to all approved tires on AMG 
vehicles. For information on tested and 
approved tires for AMG vehicles, contact an 
authorized Mercedes-Benz Center.
MOE = Mercedes-Benz Original Extended 
(tires with limited run-flat characteristics) 
original equipment tires
Using tires other than those approved by 
Mercedes-Benz may result in damage that is not 
covered by the Mercedes-Benz Limited 
Warranty.
iFor information on driving with MOExtended 
tires, see “MOExtended system*” (
page 414).
!Using tires other than those approved by 
Mercedes-Benz can have detrimental effects, 
such as
poor handling characteristics
increased noise
increased fuel consumption
Moreover, tires and rims not approved by 
Mercedes-Benz may, under load, exhibit 
dimensional variations and different tire defor-
mation characteristics that could cause them to 
come into contact with the vehicle body or axle 
parts. Damage to the tires or the vehicle may be 
the result.
iFurther information on tires and rims is 
available at any authorized Mercedes-Benz 
Center. A placard with the recommended tire 
inflation pressures is located on the driver’s door 
B-pillar. Some vehicles may have supplemental 
tire inflation pressure information for driving at 
high speeds (
page 313) or for vehicle loads 
less than the maximum loaded vehicle condition 
(
page 313). If such information is provided, it 
can be found on the placard located on the in-
side of the fuel filler flap.The tire inflation pressure should be checked 
regularly and should only be adjusted on cold 
tires. Follow tire manufacturer’s maintenance 
recommendation included with vehicle.
iThe following pages also list the approved 
wheel rim and tire sizes for equipping your 
vehicles with winter tires. Winter tires are not 
available as standard or optional factory 
equipment, but can be purchased from an 
authorized Mercedes-Benz Center.
Depending on vehicle model and the standard or 
optional factory-equipped wheel rim/tire config-
uration on your vehicle (Performance Package, 
Sport Package etc.), equipping your vehicle with 
winter tires approved for your vehicle model may 
also require the purchase of two or four wheel 
rims of the recommended size for use with these 
winter tires. Contact an authorized 
Mercedes-Benz Center for more information.
