When you use the cruise control lever to de-
celerate, the brake system will automatically
brake the vehicle if the engine’s braking power
does not brake the vehicle sufficiently.
Warning!
G
The set speed stored in memory should only
be set again if prevailing road conditions
permit. Possible acceleration or decelera-
tion differences arising from returning to the
preset speed could cause an accident
and/or serious injury to you and others.

Driving systems
Distronic*
When activated, the Distronic adaptive
cruise control system increases the driving
convenience afforded by the cruise control
while traveling on expressways and other
major roadways.
If the Distronic distance sensor detects
a slower moving vehicle directly ahead,
your vehicle’s speed will be reduced so
that you follow that vehicle at the pre-
set following distance.
If there is no vehicle directly ahead of
you, Distronic will function in the same
way as standard cruise control
(page 209).
Warning!
G
Distronic adaptive cruise control is not a
substitute for active driving involvement. It
does not react to pedestrians or stationary
objects, recognize or predict the lane curva-
ture nor the movement of preceding
vehicles.
Distronic can only apply a maximum of 20%
of the vehicle’s braking power.
It is the driver’s responsibility at all times to
be attentive to the road, weather and traffic
conditions. In addition, the driver must pro-
vide the steering, braking and other driving
inputs necessary to remain in control of the
vehicle.Warning!
G
Distronic is a convenience system. Its speed
adjustment reduction capability is intended
to make cruise control more effective and
usable when traffic speeds vary. It is not
however, intended to, nor does it, replace
the need for extreme care. The responsibili-
ty for the vehicle’s speed, distance to the
preceding vehicle and, most importantly,
brake operation to assure a safe stopping
distance, always rests with the driver.
Warning!
G
Distronic requires familiarity with its opera-
tional characteristics. We strongly recom-
mend that you review the following
information carefully before operating the
system.Warning!
G
Distronic cannot take street and traffic con-
ditions into account. Only use Distronic if
the road, weather and traffic conditions
make it advisable to travel at a constant
speed.

The Distronic system is operated by means
of the cruise control lever.
The cruise control lever is the uppermost
lever found on the left-hand side of the
steering column.

4Activating Distronic or resuming at last
set speedActivating Distronic
You can activate Distronic when the vehi-
cle speed is between 20 mph (30 km/h)
and 110 mph (180 km/h).
When Distronic is activated, the left multi-
function display will show a message such
as
DTR 55 mph
.
If Distronic is not activated after the cruise
control lever is pulled, the left multifunc-
tion display will show the message

In the following cases you cannot activate
Distronic:

gine

deactivate Distronic. After brief acceleration
(e.g. for passing), the cruise control will resume
the last speed set.

When you use the cruise control lever to de-
celerate, the brakes will be applied to support
deceleration.
In addition, the transmission will automatically
downshift on long downhill grades.

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. Try
to keep the vehicle under control by cor-
rective steering action.
i
For information on tire speed rating for win-
ter tires, see “All-season and winter tires”
(
page 306).
For additional general information on tire speed
markings on tire sidewall, see “Tire speed rating”
(page 304).
i
For information on driving with snow chains,
see “Snow chains” (
page 318).
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.
