162 Controls in detail
Automatic transmission*
Press program mode selector switch 
repeatedly until the letter of the 
desired program mode appears in the 
multifunction display.
SelectCfor comfort driving:
The vehicle starts out in second 
gear (both forward and reverse) for 
gentler starts. This does not apply if 
full throttle is applied or gear 
range1 is selected.
Traction and driving stability are 
improved on icy roads.
Upshifts occur earlier even when 
you give more gas. The engine then 
operates at lower rpms and the 
wheels are less likely to spin.
SelectSfor standard driving:
The vehicle starts out in first gear.
Upshifts occur later.Gear selector lever one-touch 
gearshifting
With the gear selector lever in drive posi-
tion D and driving in program modeC orS, 
you can limit or extend the gear range.
If your vehicle is equipped with manual 
shift programM, you can use the gear 
selector lever to manually shift the gears.
The following instructions describe opera-
tion of the gear selector lever when driving 
in the automatic program modeC orS.Limiting gear range
Briefly press the gear selector lever to 
the left in theD-direction.
The transmission will shift to the next 
lower gear as permitted by the shift 
program. This action simultaneously 
limits the gear range of the transmis-
sion (
page 160).
iFor information on using the gear selector 
lever in program modeM, see “Manual shift 
program*” (
page 165).
!Allow engine to warm up under low load use. 
Do not place full load on the engine until the 
operating temperature has been reached.
Shift into reverse gearR or park positionP only 
when the vehicle is stopped.
Avoid spinning of a drive wheel for an extended 
period when driving off on slippery road 
surfaces. This may cause serious damage to the 
drivetrain 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.
iTo avoid overrevving the engine when down-
shifting, the transmission will not shift to a lower 
gear if the engine’s max. speed would be 
exceeded.

286 Operation
Driving instructions
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 gear selector lever* to positionN or 
declutch in case of manual transmission. 
Try to keep the vehicle under control by 
corrective steering action.Road salts and chemicals can adversely af-
fect braking efficiency. Increased pedal 
force may become necessary to produce 
the normal brake effect.
Depressing the brake pedal periodically 
when traveling at length on salt-strewn 
roads can bring road-salt-impaired braking 
efficiency back to normal.
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.
For more information, see “Winter driving” 
(
page 335).
iFor information on driving with snow chains, 
see “Snow chains” (
page 336).
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 control loss.
Warning!G
Make sure not to endanger any other road 
users when carrying out these braking ma-
neuvers.
Warning!G
If the vehicle becomes stuck in snow, make 
sure snow is kept clear of the exhaust pipe 
and from around the vehicle with the 
engine running. Otherwise, deadly carbon 
monoxide (CO) gases may enter the vehicle 
interior, resulting in unconsciousness and 
death.
To assure sufficient fresh air ventilation, 
open a window slightly on the side of the 
vehicle not facing the wind.
Warning!G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and 
is therefore unsuitable for that purpose. 
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice.

288 Operation
Driving instructions
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 
instructions regarding use of an external 
antenna.Catalytic converter
Your Mercedes-Benz is equipped with 
monolithic-type catalytic converters, an 
important element in conjunction with the 
oxygen sensors to achieve substantial 
control of the pollutants in the exhaust 
emissions. Keep your vehicle in proper 
operating condition by following our 
recommended maintenance instructions 
as outlined in your Maintenance Booklet.
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 
personal injury.
!To prevent damage to the catalytic 
converters, use only premium unleaded gasoline 
in this vehicle.
Any noticeable irregularities in engine operation 
should be repaired promptly. 
Otherwise, excessive unburned fuel may reach 
the catalytic converter, causing it to overheat 
and potentially start a fire.
Warning!G
As with any vehicle, do not idle, park or op-
erate this vehicle in areas where combusti-
ble materials such as grass, hay or leaves 
can come into contact with the hot exhaust 
system, as these materials could be ignited 
and cause a vehicle fire.
