223 Controls in detail
Driving systems
Setting a lower speed
Briefly tip the cruise control lever in di-
rection of arrow2 (
page 221) to de-
crease vehicle speed in increments of
5 mph (Canada: 10 km/h).
The new speed is set.
The stored speed is displayed in the
multifunction display for approximately
five seconds (
page 221), and one or
two segments around the stored speed
come on the speedometer
(
page 219).Fine adjustment in 1 mph
(Canada: 1 km/h) increments
Faster

Briefly tip the cruise control lever in di-
rection of arrow4 (
page 221).Setting to last stored speed (“Resume”
function)

Briefly tip the cruise control lever in di-
rection of arrow4 (
page 221).
Distronic is set to the last stored
speed.

Remove your foot from the accelerator
pedal.
iWhen you use the cruise control lever
to decelerate, the transmission will au-
tomatically downshift if the rate of de-
celeration is too low.
Warning!
G
The speed stored in memory should only be
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to preset
speed could cause an accident and/or seri-
ous injury you and others.

224 Controls in detailDriving systemsDeactivating Distronic
There are several ways to deactivate the
Distronic system:
Briefly tip the cruise control lever in di-
rection of arrow3 (
page 221).
or

Step on the brake pedal.
Distronic will be deactivated. The last
speed set will be stored into memory.Distronic deactivates automatically when:


you set the parking brake


you drive slower than 22 mph
(35 km/h)


the ESP is active (
page 82) or you de-
activate the ESP


you move the gear selector lever into
positionN
A si gnal wi ll s ound. T he

message appears in the multifunction
display for approximately five seconds.Setting the following distance in
Distronic
You can set the specified following dis-
tance for Distronic by varying the time set-
ting between 1.0 and 2.0 seconds. Using
this time setting and the current speed of
your vehicle, Distronic calculates and sets
the required following distance to the vehi-
cle ahead. The set distance will be shown
in the multifunction display field.
iThe following message will appear in
the multifunction display for approxi-
mately five seconds:
DISTRONIC OFF
.
The last stored speed is deleted when
you turn off the engine.
Warning!
G
Distronic switches off and releases the
brakes when the vehicle decelerates below
the minimum speed of approximately
22 mph (35 km/h) by operation of the sys-
tem. At that time the driver must apply the
brakes in order to reduce vehicle speed fur-
ther or bring it to a stop.
Warning!
G
It is up to the driver to exercise discretion to
select the appropriate setting given road
conditions, traffic, driver’s preferred driving
style and applicable laws and driving recom-
mendations for safe following distance.

279 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 position N. Try
to keep the vehicle under control by cor-
rective steering action.Road salts and chemicals can adversely af-
fect braking efficiency. Increased pedal
force may become necessary to produce
the normal braking 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 on winter driving, see
“Winter driving” (
page 326).
iFor information on driving with snow
chains, see “Snow chains”
(page 327).
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 that 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 vehicle in-
terior resulting in unconsciousness and
death.
To assure sufficient fresh air ventilation,
open a window slightly on the side of the ve-
hicle 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. In-
dicated temperatures just above the freez-
ing point do not guarantee that the road
surface is free of ice.

The control system is used to call up
vehicle information and to change
component settings. Information and
messages appear in the multifunction
display. The driver uses the buttons on
the multifunction steering wheel to
navigate through the system and to ad-
just settings.
Cruise control
Driving convenience system that auto-
matically maintains the vehicle speed
set by the driver.Distronic*
A driving convenience cruise control
system which helps the driver maintain
a pre-selected speed:


If there is no vehicle directly ahead,
the system operates in the same
way as conventional ->cruise con-
trol.


If a slower moving vehicle is ahead,
Distronic will reduce your vehicle
speed to the extent permitted by re-
duced throttle and up to 20% brak-
ing power to maintain the preset
minimum following distance.
