Exhaust check
G
WARNING
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do not
run the engine in confined areas (such
as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are
entering the vehicle while driving, have the
cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open at all times.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with
the manufacturer's specifications. All work
on the engine must be carried out by qualified
and authorized Mercedes-Benz technicians.
The engine settings must not be changed
under any circumstances. Furthermore, all
specific service work must be carried out at
regular intervals and in accordance with the
Mercedes-Benz service requirements. Details
can be found in the Maintenance Booklet. Brakes
Important safety notes G
WARNING
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. G
WARNING
Make sure that you do not endanger other
road users when you apply the brakes. Downhill gradients !
On long, steep gradients, you must
reduce the load on the brakes. In order to
use engine

braking effect, restrict the shift
range in good time. This helps you to avoid
overheating the brakes and wearing them
out excessively.
When making use of the engine braking
effect, it is possible that a drive wheel may
not turn for some time, e.g. in the case of
suddenly changing or slippery road surface
conditions. This could cause damage to the
drive train. This type of damage is not
covered by the Mercedes-Benz warranty.
Heavy and light loads G
WARNING
Depressing the brake pedal constantly results
in excessive

and premature wear to the brake
pads.
It may also cause the brakes to overheat,
seriously impairing their effectiveness. It may
then not be possible to stop the vehicle in
sufficient time to avoid an accident.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the
airflow to cool the brakes more quickly.
Wet roads G
WARNING
After driving in heavy rain for some time
without applying

the brakes or through water
deep enough to wet brake components, the
first braking action may be somewhat
reduced. You have to depress the brake pedal
more firmly. Maintain a safe distance from
vehicles in front.
After driving on a wet road or having the
vehicle washed, brake firmly while paying
attention to the traffic conditions. This will
warm up the brake discs, thereby drying them 158
Driving tips
Driving and parking

If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X
Shift the transmission to position N.
Drive particularly carefully on slippery road
surfaces. Avoid
sudden acceleration, steering
and braking maneuvers. Do not use cruise
control.

Cruise control
Important safety notes G
WARNING
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle's speed
and for safe brake operation.
Only use

the cruise control if the road, traffic,
and weather conditions make it advisable to
travel at a constant speed.
R The use of the cruise control can be
dangerous on winding roads or in heavy
traffic because conditions do not allow safe
driving at a constant speed.
R The use of the cruise control can be
dangerous on slippery roads. Rapid
changes in tire traction can result in wheel
spin and loss of control.
R Deactivate the cruise control when driving
in fog.
The "Resume" function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed. G
WARNING
The cruise control brakes automatically so
that the set speed is not exceeded. General notes Cruise control maintains a constant road
speed
for

you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select shift range
1, 2 or 3 in good time (Y page 149). By doing
so, you will make use of the braking effect of
the engine, which relieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly.
Use cruise control only if road and traffic
conditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 20 mph
(30 km/h).

G
WARNING
DISTRONIC PLUS distance is not a substitute
for the

active intervention of the driver. It does
not detect pedestrians or stationary objects,
nor can it detect, recognize or predict the
road's course or the movements of vehicles
in front. DISTRONIC PLUS can only brake the
vehicle using 40% of the vehicle's maximum
available brake force.
DISTRONIC PLUS may not detect narrow
vehicles driving in front, e.g. motorcycles, or
vehicles driving in the lane beyond the lane
next to your vehicle, especially if the vehicles
are not driving on the middle of their lane.
The driver must always pay careful attention
to the road, weather and traffic conditions.
The driver must drive, steer and brake in a
manner which will allow him to always have
control of the vehicle.
Sources of high-frequency radio waves, such
as toll stations, speed-measuring radar, etc.,
can cause DISTRONIC PLUS to fail
temporarily. G
WARNING
The DISTRONIC PLUS cannot take road and
traffic conditions into account. Only use the
DISTRONIC PLUS if the road, weather and
traffic conditions make it advisable to travel
at a constant speed. G
WARNING
Use of the DISTRONIC PLUS can be
dangerous on slippery roads. Rapid changes
in tire traction can result in wheel spin and
loss of control.
The DISTRONIC PLUS does not function in
adverse sight

and distance conditions. Do not
use the DISTRONIC PLUS during conditions of
fog, heavy rain, snow or sleet. G
WARNING
The DISTRONIC PLUS cannot take weather
conditions into account. Switch off the
DISTRONIC PLUS or do not switch it on if:
R roads are

slippery or covered with snow or
ice. The wheels could lose traction while
braking or accelerating, and the vehicle
could skid.
R the DISTRONIC PLUS system sensor covers
are dirty or visibility is diminished due to
snow, rain or fog, for example. The distance
control system functionality could be
impaired.
Always pay attention to surrounding traffic
conditions even while the DISTRONIC PLUS is
switched on. Otherwise, you may not be able
to recognize dangerous situations until it is
too late. This could cause an accident in which
you and/or others could be injured. G
WARNING
The "Resume" function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed. G
WARNING
Your undivided attention to street and traffic
conditions is necessary at all times whether
DISTRONIC PLUS is active or not.
The use of DISTRONIC PLUS can be
dangerous on

winding roads or in heavy traffic
because conditions do not allow safe driving
at a constant speed.
DISTRONIC PLUS does not react to stationary
objects on the road (for example, a vehicle
stopped in traffic or an abandoned vehicle).
DISTRONIC PLUS likewise does not react to
oncoming vehicles. Driving systems

exiting a parking space. You may also use
PARKTRONIC (
Y page 183). When
PARKTRONIC is switched off, Active Parking
Assist is also unavailable.
Parking tips:
R pay attention to the PARKTRONIC
(Y page
185) warning messages during the
parking procedure.
R you can intervene in the steering procedure
to correct it at any time. Active Parking
Assist will then be canceled.
R when transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R never use Active Parking Assist when snow
chains or an emergency spare wheel are
mounted.
R make sure that the tire pressures are
always correct. This has a direct influence
on the parking characteristics of the
vehicle.
Parking Detecting a parking space
G
WARNING
Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated, e.g. overhanging
loads, tail

sections or loading ramps of goods
vehicles. In some circumstances, Active
Parking Assist may therefore guide you into
the parking space too early. This may lead to
a collision. For this reason, you should avoid
using Active Parking Assist in such situations. G
WARNING
Active Parking Assist is merely an aid and may
sometimes recommend parking spaces that
are not suitable for parking. For example,
these might be spaces where parking is
prohibited, driveways, unsuitable surfaces,
etc. Active Parking Assist measures the parking
space as you drive past it. Any later changes
to the parking space are not taken into
account. For instance, this may be the case
when
the

vehicle parked in front of or behind
the space changes its position or when an
obstacle is moved into the parking space.
Active Parking Assist does not relieve you of
the responsibility of paying attention. If you
rely solely on Active Parking Assist, you could
cause an accident and injure yourself and
others.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
maneuvering. Example: detected parking space
Active Parking Assist is switched on
automatically when driving forwards. The
system is operational at speeds of up to
approximately
22 mph (35 km/h

). While in
operation, the system independently locates
and measures parking spaces on both sides
of the vehicle. At a speed below 19 mph
(30 km/h), you will see parking symbol ; as
the status indicator in the instrument cluster.
If a parking space has been detected, an
arrow pointing to the right = or left : is also
displayed.
By default, Active Parking Assist only displays
parking spaces on the front-passenger side.
Parking spaces on the driver's side are
displayed as soon as the turn signal on the
driver's side is activated. If you wish to park
in a space on the driver's side, the indicator
on the driver's side must remain on. The turn
signal must remain switched on until you
acknowledge the use of Active Parking Assist Driving systems

or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
R snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R the way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the
position and shape of the vehicles parked
in front and behind it and the conditions of
the location. In some cases, Active Parking
Assist may guide you too far into a parking
space, or not far enough into it. In some
cases, it may also lead you across or onto
the curb. If necessary, you should abort the
parking procedure with Active Parking
Assist.
R you can also engage forward gear
prematurely. The vehicle redirects and
does not drive as far into the parking space.
Should a gear be changed too early, the
parking procedure will be canceled. A
sensible parking position can no longer be
