Driving systems
1Set current or higher speed
2Set current or lower speed
3Cancel cruise control
4Resume at previously set speed
Saving current speed
Accelerate or decelerate to the desired
speed.
Briefly lift1 or depress2 the cruise
control lever.
The current speed is set.
Remove your foot from the accelerator
pedal.
Cruise control is activated.Canceling cruise control
There are several ways to cancel cruise
control:
Step on the brake pedal.
or
Briefly push the cruise control lever to
position3.
Cruise control will be canceled. The
last speed set will be stored for later
use.iOn uphill or downhill grades, cruise
control may not be able to maintain the
set speed. Once the grade eases, the
set speed will be resumed.
!Vehicles with automatic transmission:
Moving gear selector lever to
positionN while driving also cancels
cruise control. However, the gear se-
lector lever should not be moved to
positionN while driving except to coast
when the vehicle is in danger of skid-
ding (e.g. on icy roads).iVehicles with manual transmission:
The set cruise controlled speed is
switched off when declutching exceeds
four seconds during downshifting a
gear.iThe last stored speed is canceled when
you turn off the engine.

254 OperationDriving instructionsTire speed rating
Your vehicle is factory equipped with
"H"-rated tires, which have a speed rating
of 130 mph (210 km / h).
An electronic speed limiter prevents your
vehicle from exceeding the speed rating.
Regardless of the tire rating, local speed
limits should be obeyed. Use prudent driv-
ing speeds appropriate to prevailing condi-
tions.
Winter driving instructions
The most important rule for slippery or icy
roads is to drive sensibly and to avoid
abrupt acceleration, braking and steering
maneuvers. Do not use the cruise control
system under such conditions.
When the vehicle is in danger of skidding,
move selector lever to position N or in
case you have a manual transmission, de-
clutch. Try to keep the vehicle under con-
trol by corrective steering action.Road salts and chemicals can adversely af-
fect braking efficiency. Increased pedal
force may become necessary to produce
the normal braking effect.
We therefore recommend depressing the
brake pedal periodically when traveling at
length on salt-strewn roads.
This can bring road salt impaired braking
efficiency back to normal. A prerequisite
is, however, that this be done without en-
dangering other drivers on the road.
If the vehicle is parked after being driven
on salt-treated roads, the braking efficien-
cy should be tested as soon as possible af-
ter driving is resumed while observing the
safety rules in the previous paragraph.
Warning!
G
Even when permitted by law, never operate
a vehicle at speeds greater than the maxi-
mum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire fail-
ure, causing loss of vehicle control and re-
sulting in personal injury and possible death.
iFor more information on driving with
snow chains, see "Snow chains"
(page 274).
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.

378 Technical termsMenu
The control system displays are ar-
ranged in menus. Each menu contains
a number of commands for particular
systems. In the Audio menu, for exam-
ple, you will find the commands
SELECT RADIO STATION or
OPERATE CD
PLAYER
. Using commands you can di-
rectly change the settings for your ve-
hicle.
MON
(M
otor O
ctane N
umber)
The Motor Octane Number for gasoline
as determined by a standardized meth-
od. It is an indication of a gasoline's
ability to resist undesired detonation
(knocking). The average of both the
MON (Motor Octane Number) and
->RON (Research Octane Number) is
posted at the pump, also known as
ANTI-KNOCK INDEX.Multifunction display
The display field in the instrument clus-
ter used to present information provid-
ed by the control system.
Multifunction steering wheel
Steering wheel with buttons for operat-
ing the control system.
Overspeed range
Engine speeds within the red marking
of the tachometer dial. Avoid this en-
gine speed range, as it may result in se-
rious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
Poly-V-belt drive
Drives engine-components (alternator,
AC compressor, etc.) from the engine.Power train
Collective term designating all compo-
nents used to generate and transmit
motive power to the drive axles, includ-
ing:
Engine
Clutch/torque converter
Transmission
Transfer case*
Drive shaft
Axle shafts/axles
Program mode selector switch
Used to switch the automatic transmis-
sion between standard operationS and
winter operationW.
Remote Vehicle Diagnostics
Transmission of vehicle data and cur-
rent location to the Mercedes-Benz
Customer Assistance Center for sub-
scribers to the Tele Aid service.
