Characteristics of ESP®
General information
If the÷ ESP warning lamp goes out before
beginning the journey, ESP
®is automatically
active.
If ESP
®intervenes, the ÷ESP®warning
lamp flashes in the instrument cluster.
If ESP
®intervenes:
XDo not deactivate ESP®under any circum-
stances.
XOnly depress the accelerator pedal as far as
necessary when pulling away.
XAdapt your driving style to suit the prevail-
ing road and weather conditions.
ECO start/stop function
The ECO start/stop function switches the
engine off automatically when the vehicle
stops moving. The engine starts automati-
cally when the driver wants to pull away again.
ESP
®remains in its previously selected sta-
tus. Example: if ESP®was deactivated before
the engine was switched off, ESP®remains
deactivated when the engine is switched on
again.
Deactivating/activating ESP®
Important safety notes
You can select between the following states
of ESP
®:
RESP®is activated.
RESP®is deactivated.
GWARNING
If you deactivate ESP
®, ESP®no longer sta-
bilizes the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP
®in the situations descri-
bed in the following.
It may be best to deactivate ESP®in the fol-
lowing situations:
Rwhen using snow chains
Rin deep snow
Ron sand or gravel
iActivate ESP®as soon as the situations
described above no longer apply. ESP®will
otherwise not be able to stabilize the vehi-
cle if the vehicle starts to skid or a wheel
starts to spin.
!Avoid spinning the driven wheels for an
extended period with ESP®deactivated.
You could otherwise damage the drivetrain.
Deactivating/activating ESP

engine's air suction nozzles and this can
cause engine damage.
iVehicles with the AIRMATIC package:
set the raised level before driving through
standing water.
Off-road fording
!Under no circumstances should you
accelerate before entering the water. The
bow wave could cause water to enter and
damage the engine and other assemblies.
!Do not open any of the vehicle's doors
while fording. Otherwise, water could get
into the vehicle interior and damage the
vehicle's electronics and interior equip-
ment.
REstablish how deep the water is and the
characteristics of the body of water before
fording.
RSelect the highest possible vehicle level.
RShift to a lower gear using the left-hand
steering wheel paddle shifter.
RAvoid high engine speeds.
REnter and exit the water at a flat place and
at a steady walking pace.
RDrive slowly and at an even speed through
the water.
REnsure that a bow wave does not form as
you drive.
RDo not stop and do not switch off the
engine. Water offers a high degree of resist-
ance, and the ground is slippery and in
some cases unstable. Therefore, it is diffi-
cult and dangerous to pull away in the
water.
RClean any mud from the tire tread after
fording.
RApply the brakes to dry them after fording.
Always observe the fording depth values
(
Ypage 455).
Winter driving
GWARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a
window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winter-proofed at a quali-
fied specialist workshop at the onset of win-
ter.
Drive particularly carefully on slippery road
surfaces. Avoid sudden acceleration, steeringand braking maneuvers. Do not use the cruise
control or DISTRONIC PLUS.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift the transmission to position N.
Vehicles with the ON&OFFROAD package:
if driving in snow or with snow chains, select
the snow program (
Ypage 255) with the off-
road program selector wheel in the center
console.
iVehicles with a diesel engine: do not
cover the radiator, e.g. with a protective
cover. The measuring function of the on-
board diagnosis system may otherwise pro-
vide inaccurate values. Some of these val-

ues are requiredbylaw and must therefore
always beaccurate.
The outside temperature indicator isnot
designed to serve as an ice-warning device
and istherefore unsuitable for that purpose.
Changes inthe outside temperature are dis-
played after a short delay.
Indic ated temperatures just above the freez-
ing poin tdo not guarantee that the road sur-
face isfree of ice. The road may still beicy,
especial ly inwooded areas or on bridges. You
should pay special attention to road condi-
tions when temperatures are around the
freezing point.

!There isa risk of damage to the vehicle if:
Rthe vehicle becomes stuck, e.g. on a high
curb or an unpaved road
Ryou drive too fast over an obstacle, e.g. a
curb or a hole inthe road
Ra heavy object strikes the undercarriage
or parts of the chassis
In situations like this, the body, the under-
carriage, chassis parts, wheels or tires
could bedamaged without the damage
being visible. Components damaged inthis
way can unexpectedly fail or, inthe case of
an acc ident, no longer withstand the strain
they are designed to.
If the underbody paneling isdamaged,
combusti blematerials such as leaves,
grass or twigs can gather between the
underbody and the underbody paneling. If
these materials come incontact with hot
parts of the exhaust system, they can catch
fire.
In such situations, have the vehicle
checked and repaired immediately at a
qualif ied specialist workshop. Ifon con-

When driving off-road, substances such as
sand, mud and water or water mixed with oil
may get into the brakes. This could result ina
reduced braking effect or intotal brake failure
and also inincreased wear and tear. The brak-
ing characteristics change depending on the
material ingressing the brakes. Clean the
brakes after driving off-road. Ifyou detect a

198Driving tips
Driving and parking

Parking tips:
ROn narrow roads, drive as close to the park-
ing space as possible.
RParking spaces that are littered or over-
grown might be identified or measured
incorrectly.
RParking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly.
RSnowfall or heavy rain may lead to a parking
space being measured inaccurately.
RPay attention to the PARKTRONIC
(
Ypage 225) warning messages during the
parking procedure.
RAt any time, you can intervene in the steer-
ing procedure to correct it. Active Parking
Assist will then be canceled.
RWhen transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
RNever use Active Parking Assist when snow
chains are installed.
RMake sure that the tire pressures are
always correct. This has a direct influence
on the parking characteristics of the vehi-
cle.
Use Active Parking Assist for parking spaces:
Rthat are parallel to the direction of travel
Rthat are on straight roads, not bends
Rthat are on the same level as the road, e.g.
not on the pavement
Detecting parking spaces
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.
GWARNING
If there are objects above the detection range, Active Parking Assist may turn prematurely.
You may cause a collision as a result. There is
a risk of an accident.
If there are objects above the detection range,
stop and deactivate Active Parking Assist.
For further information on the detection
range (
Ypage 224).
Active Parking Assist does not support you
parking in spaces that are parallel to the
direction of travel if:
Rthe parking space is on a curb
Rthe system reads the parking space as
being blocked, for example by foliage or
grass paving blocks
Rthe area is too small for the vehicle to
maneuver into
Rthe parking space is bordered by an obsta-
cle, e.g. a tree, a post or a trailer
:Detected parking space on the left
;Parking symbol
=Detected parking space on the right
Active Parking Assist is switched on automat-
ically 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.
Active Parking Assist will only detect parking
spaces:
Rthat are parallel to the direction of travel
Rthat are at least 59 in (1.5 m) wide
Rthat are at least 39.5 in (1.0 m) longer than
your vehicle
When driving at speeds below 19 mph
(30 km/h), you will see the parking symbol as
a status indicator in the instrument cluster.

!A function or performance test should
only be carried out on a two-axle dyna-
mometer. Before you operate the vehicle
on such a dynamometer, please consult a
qualified workshop. You could otherwise
damage the drive train or the brake system.
iIn wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.

(
Ypage 198).
DSR (Downhill Speed Regulation)
General notes
DSR is an aid to assist you when driving down-
hill. It keeps the speed of travel at the speed
selected on the on-board computer. The
steeper the downhill gradient, the greater the
DSR braking effect on the vehicle. When driv-
ing on flat stretches of road or on an uphill
gradient, the DSR braking effect is minimal or
nonexistent.
DSR controls the vehicle’s speed when it is
activated and the transmission is in position
D ,R or N. You can drive at a higher or a lower
speed than that set on the on-board computer
at any time by accelerating or braking.
Important safety notes
GWARNING
If the speed driven and the set speed deviate and you activate DSR on a slippery road sur-
face, the wheels may lose traction. There is an
increased danger of skidding and accidents.
Before switching DSR on, please take into
consideration the road surface and the differ- ence between driving speed and the set
speed.
If you fail to adapt your driving style, DSR can
neither reduce the risk of accident nor over-
ride the laws of physics. DSR cannot take
account of road, weather and traffic condi-
tions. DSR is only an aid. You are responsible for the distance to the vehicle in front, for
vehicle speed, for braking in good time and for
staying in your lane.
You are always responsible for keeping con-
trol of the vehicle and for assessing whether
the downhill gradient can be managed. DSR
may not always be able to keep to the set
speed, depending on road surface and tire
conditions. Select a set speed suitable for the
prevailing conditions and when necessary,
apply the brakes manually.
Activating DSR
