(page 195).
The transmission shifts to the next 
higher gear.
If, instead of the manual program mode 
symbolM, thep symbol appears in the 
multifunction display (

the next higher gear. The fuel supply will 
otherwise be interrupted to prevent the 
engine from overrevving.If you have selected the AMG menu in the 
control system and you are driving in the 
manual program modeM, upshift

Briefly press the gear selector lever to 
the left in theD-direction.
or
Briefly pull left shift paddle1 
(page 195).
The transmission shifts to the next 
lower gear.
!
In the manual program modeM, the trans-
mission will not upshift, even if the engine has 
reached its overrevving range. Shift up to the 
next gear before the engine has reached its over-
revving range. Make absolutely certain that the 
engine speed does not reach the red marking on 
the tachometer (
page 26). Otherwise the 
engine could be damaged which is not covered 
by the Mercedes-Benz Limited Warranty.
Warning!
G
On slippery road surfaces, never downshift 
in order to obtain braking action. This could 
result in drive wheel slip and reduced 
vehicle control. Your vehicle’s ABS will not 
prevent this type of loss of control.i
When you brake or stop, the transmission 
shifts down to a gear from which you can easily 
accelerate or take off.

318 OperationDriving instructionsControl and operation of radio trans-mitter
COMAND, radio and telephone*Telephones and two-way radios
Radio transmitters, such as a portable tele-
phone or a citizens band unit should only 
be used inside the vehicle if they are con-
nected to an antenna that is installed on 
the outside of the vehicle.
Refer to the radio transmitter operation in-
structions regarding use of an external an-
tenna.
Catalytic converter
Your vehicle is equipped with 
monolithic-type catalytic converters, an 
important element in conjunction with the 
oxygen sensors to achieve substantial con-
trol of the pollutants in the exhaust emis-
sions. Keep your vehicle in proper 
operating condition by following our rec-
ommended maintenance instructions as 
outlined in your Maintenance Booklet.
Warning!
G
Please do not forget that your primary re-
sponsibility is to drive the vehicle safely. 
Only operate the COMAND (Cockpit Man-
agement and Data System), radio or tele-
phone
1 if road, weather and traffic 
conditions permit.
Bear in mind that at a speed of just 30 mph 
(approximately 50 km/h), your vehicle is 
covering a distance of 44 feet (approximate-
ly 14 m) every second.
1Observe all legal requirements.
Warning!
G
Never operate radio transmitters equipped 
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna) 
from inside the vehicle while the engine is 
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or serious 
personal injury.
!
To prevent damage to the catalytic convert-
ers, only use premium unleaded gasoline in this 
vehicle.
Any noticeable irregularities in engine operation 
should be repaired promptly. Otherwise, exces-
sive unburned fuel may reach the catalytic con-
verter, causing it to overheat, which could 
potentially start a fire.

Tire and loading terminology
Accessory weight
The combined weight (in excess of those 
standard items which may be replaced) of 
automatic transmission, power steering, 
power brakes, power windows, power 
seats, radio, and heater, to the extent that 
these items are available as 
factory-installed equipment (whether 
installed or not).
Air pressure
The amount of air inside the tire pressing 
outward on each square inch of the tire. 
Air pressure is expressed in pounds per 
square inch (psi), or kilopascal (kPa) or 
bar.
Aspect ratio
Dimensional relationship between tire 
section height and section width 
expressed in percentage.Bar
Another metric unit for air pressure. There 
are 14.5038 pounds per square inch (psi) 
to 1 bar; there are 100 kilopascals (kPa) 
to 1 bar.
Bead
The tire bead contains steel wires wrapped 
by steel cords that hold the tire onto the 
rim.
Cold tire inflation pressure
Tire inflation pressure when your vehicle 
has been sitting for at least 3 hours or driv-
en no more than 1 mile (1.6 km). 
Curb weight
The weight of a motor vehicle with stan-
dard equipment including the maximum 
capacity of fuel, oil, and coolant, and, if so 
equipped, air conditioning and additional 
optional equipment, but without passen-
gers and cargo.
