Setting the following distance in
DISTRONIC Plus
You can set the specified following dis-
tance for DISTRONIC Plus by varying the
time setting between 1.0 and 2.0 seconds.
Using this time setting and the current set
speed of your vehicle, DISTRONIC Plus cal-
culates and sets the required following dis-
tance to the vehicle ahead. The set
distance will be shown in the multifunction
display.The distance setting switch for the target
distance is located on the DISTRONIC Plus
lever.

rection 2.
Warning!
G
DISTRONIC Plus switches off and releases
the brakes when the vehicle decelerates be-
low the minimum speed of 20 mph
(30 km / h) by operation of the system un-
less DISTRONIC Plus detects a vehicle di-
rectly ahead of you. At that time the driver
must apply the brakes in order to reduce ve-
hicle speed further or bring it to a stop.!
Setting the automatic transmission toN
while driving cancels the DISTRONIC Plus. How-
ever, the automatic transmission should not be
set toN while driving except to coast when the
vehicle is in danger of skidding (e.g. on icy
roads).
i
Depressing the accelerator pedal does not
deactivate DISTRONIC Plus. After brief accelera-
tion (e.g. for passing), DISTRONIC Plus will re-
sume the last speed set.
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.

Park Assist*
Park Assist is an electronic parking aid
with radar sensors that helps you while
parking.
It visually and audibly indicates the relative
distance between the vehicle and an ob-
stacle.Park Assist is automatically activated
when the engine is running and the trans-
mission is in position D, R or N.
The Park Assist system deactivates at
speeds over approximately 11 mph
(18 km/h). At lower speeds the Parktronic
system turns on again.
Park Assist is also switched off when the
transmission is in position P or switch off
the engine.
While the transmission is in position N,
Park Assist is switched off if you secure the
vehicle in place with the electric parking
brake.
The Park Assist system monitors the sur-
roundings of your vehicle with four sensors
in the front bumper and two sensors in the
rear bumper.Warning!
G
Park Assist is a supplemental system. It is
not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always rests with the driver.Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.!
Special attention must be paid to objects
with smooth surfaces or low silhouettes (e.g.
trailer couplings, painted posts, elevated cross-
bars or road curbs). Such objects may not be de-
tected by the system and can damage the
vehicle.
!
The operational function of the Park Assist
system can be affected by dirty sensors, espe-
cially at times of snow and ice.
Make sure that the area on the bumpers around
the sensors is free of dirt, ice and/or slush,
otherwise Park Assist may not function properly,
see “Cleaning the Park Assist* system sensors”
(
page 538).
!
High-frequency sources such as toll sta-
tions, speed measuring systems, etc. can cause
the Park Assist system to malfunction. You can
switch off the Park Assist using the Park Assist
button (
page 412) or switch off the radar sen-
sors (
page 256) to prevent possible malfunc-
tion.
i
In certain countries and near radio-astrolog-
ical facilities, you must switch off the radar sen-
sors (page 256).

Rolling code programming
To train a garage door opener (or other
rolling code devices) with the rolling code
feature, follow these instructions after
completing the “Programming” portion
(steps 1 through 6) of this text. (A second
person may make the following training
procedures quicker and easier.)
Step 8:

Locate “training” button on the garage
door opener motor head unit.
Exact location and color of the button
may vary by garage door opener brand.
Depending on manufacturer, the “training” button may also be referred
to as “learn”or “smart” button. If there
is difficulty locating the transmitting
button, refer to the garage door opener
operator’s manual.
Step 9:

Press the “training” button on the ga-
rage door opener motor head unit.
The “training light” is activated.
You have 30 seconds to initiate the follow-
ing two steps.

Gate operator/Canadian programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission
which may not be long enough for the
integrated signal transmitter to pick up the
signal during programming. Similar to this
Canadian law, some U.S. gate operators
are designed to “time-out” in the same
manner.
i
If the indicator lamp1 flashes rapidly for
about 2 seconds and then turns to a constant
light, continue with programming steps 8
through 12 as your garage door opener may be
equipped with the “rolling code” feature.
i
Some garage door openers (or other rolling
code equipped devices) may require you to
press, hold for 2 seconds and release the same
signal transmitter button a third time to com-
plete the training process.

Infrared reflecting windshield
Your vehicle is equipped with infrared re-
flecting glass, which reduces the amount
of radiated heat entering the vehicle interi-
or through the windows.
The infrared reflecting glass also prevents
the transmission of signals through the
glass by in-vehicle electronic devices
(e.g. electronic toll collection devices).
To allow the use of these devices in the ve-
hicle, transparent areas 1 and 3 are
placed in the windshield.
You can see them from certain angles
when ambient light condition permit.

481 Operation
Driving instructions
After hard braking, it is advisable to drive
on for some time, rather than immediately
park, so that the air stream can cool down
the brakes faster.
Driving off
Apply the brakes to test them briefly after
driving off. Perform this procedure only
when the road is clear of other traffic.
Warm up the engine smoothly. Do not
place full load on the engine until the oper-
ating temperature has been reached.
When starting off on a slippery surface, do
not allow a drive wheel to spin for an ex-
tended period with the ESP
® switched off.
Doing so may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
Parking
Warning!
G
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substantially impaired. This
could result in an accident.!
When driving down long and steep grades,
relieve the load on the brakes by shifting into a
lower gear to use the engine’s braking power.
This helps prevent overheating of the brakes and
reduces brake pad wear.
When using the engine’s braking power, a drive
wheel may not spin for an extended period of
time, e.g. on slippery road surfaces. This may
cause serious damage to the drivetrain which is
not covered by the Mercedes-Benz Limited War-
ranty.
!
Simultaneously depressing the accelerator
pedal and applying the brake reduces engine
performance and causes premature brake and
drivetrain wear.
Warning!
G
Do not park this vehicle in areas where com-
bustible 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.
To reduce the risk of personal injury as a re-
sult of inadvertent vehicle movement, be-
fore turning off the engine and leaving the
vehicle always:

Keep right foot on brake pedal.


Firmly depress parking brake pedal.


Shift the automatic transmission toP.


Slowly release brake pedal.


When parked on an incline, turn front
wheels towards the road curb.


482 OperationDriving instructions
Tires
Treadwear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and be-
come visible at a tread depth of approxi-
mately
1/16
in (1.6 mm), at which point
the tire is considered worn and should be
replaced.The treadwear indicator appears as a solid
band across the tread.
Specified tire inflation pressures must be
maintained. This applies particularly if the
tires are subject to extreme operating con-
ditions (e.g. high speeds, heavy loads, high
ambient temperatures).


Turn the SmartKey to starter switch po-
sition 0 and remove the SmartKey from
the starter switch, or press the
KEYLESS-GO* start/stop button
(page 317).


Take the SmartKey or the SmartKey with
KEYLESS-GO
* with you and lock the
vehicle when leaving.
!
Set the parking brake whenever parking or
leaving the vehicle. In addition, shift the auto-
matic transmission to P.
When parking on hills, always turn front wheels
towards the road curb.
Warning!
G
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possi-
ble damage to your vehicle has occurred,
you should turn on the hazard warning flash-
ers, carefully slow down, and drive with cau-
tio n to an a rea whic h is a s afe d ista nc e fro m
the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have the vehicle towed to
the nearest Mercedes-Benz Center or tire
dealer for repairs.
Warning!
G
Although the applicable federal motor vehi-
cle safety laws consider a tire to be worn
when the treadwear indicators (TWI) be-
come visible at approximately
1/16 in
(1.6 mm), we recommend that you do not al-
low your tires to wear down to that level. As
tread depth approaches
1/8 in (3 mm), the
adhesion properties on a wet road are
sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.


485 Operation
Driving instructions
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 530).
Standing water
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.
!
Do not drive through flooded areas or water
of unknown depth. Before driving through water,
determine its depth. Never accelerate before
driving into water. The bow wave could force wa-
ter into the engine and auxiliary equipment, thus
damaging them.
If you must drive through standing water, drive
slowly to prevent water from entering the pas-
senger compartment or the engine compart-
ment. Water in these areas could cause damage
to electrical components or wiring of the engine
or transmission, or could result in water being in-
gested by the engine through the air intake caus-
ing severe internal engine damage. Any such
damage is not covered by the Mercedes-Benz
Limited Warranty.
