Pets in the vehicle
G
WARNING
If you leave animals unsupervised or unse-
cured in the vehicle, they may push a button
or a switch, for example.
They could:
R activate vehicle equipment and become
trapped, for example
R switch vehicle systems on or off, thus
endangering other road users
In the event of an accident, sudden braking or
abrupt changes of direction, unsecured ani-
mals could be flung around the vehicle, injur-
ing the vehicle occupants. There is a risk of an accident and injury.
Never leave animals unattended in the vehi-
cle. Always secure animals correctly during a
journey, e.g. in an animal transport box. Driving safety systems
Driving safety systems overview
In this section, you will find information about
the following driving safety systems:
R ABS (Anti-lock BrakingSystem)
(Y page 64)

R PRE-SAFE ®
Brake (Y page 72)
R STEER CONTROL (Y page 74) Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of an accident nor override the laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for maintaining the distance to the
vehicle in front, for vehicle speed, for braking in
good time, and for staying in lane. Always adapt your driving style to suit the prevailing road and
weather conditions and maintain a safe distance from the vehicle in front. Drive carefully.
The driving safety systems described only work
as effectively as possible when there is ade-
quate contact between the tyres and the road
surface. Pay particular attention to the informa- tion regarding tyres, recommended minimum
tyre tread depths etc. in the "Wheels and tyres" section (Y page 348).
In wintry driving conditions, always use winter
tyres (M+S tyres) and, if necessary, snow
chains. Only in this way will the driving safety
systems described in this section work as effec-
tively as possible. ABS (Anti-lock Braking System)
General notes ABS regulates brake pressure in such a way that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from a speed of about 8 km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you only brake gently.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 64). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac- 64

Indicated temperatures just above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in wooded areas or on bridges. You should pay
special attention to road conditions when tem-
peratures are around freezing point.

tion (Y page 350). Off-road driving
Important safety notes G
WARNING
If you drive on a steep incline at an angle or
turn on a steep incline, the vehicle could slip
sideways, tip and overturn. There is a risk of
an accident.
When driving on an incline, drive into the line of fall (upwards or downwards in a straight
line) and do not turn. G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is a risk of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop. G
WARNING
If the vehicle level is high, the vehicle centre of gravity is raised. This could cause the vehicleto tip over more easily on uphill or downhill
gradients. There is a risk of an accident.
Select the lowest possible vehicle level. !
There is a risk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on a high
kerb or an unpaved road
R you drive too fast over an obstacle, e.g. a
kerb or a pothole in the road
R a heavy object strikes the underbody or
parts of the chassis
In situations like this, the body, the under-
body, chassis parts, wheels or tyres could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no longer withstand the strain they are designed
for.
If the underbody panelling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody panelling. If these materials
come in contact with hot parts of the exhaust
system, they can catch fire.
In such situations, have the vehicle checked
and repaired immediately at a qualified spe-
cialist workshop. If, upon continuing your
journey, you notice that driving safety is
impaired, pull over and stop the vehicle imme- diately, paying attention to road and traffic
conditions. In such cases, consult a qualified
specialist workshop.
When driving off-road, substances such as sand,
mud and water or water mixed with oil may get
into the brakes. This may lead to a reduction in
braking performance or total brake failure as a
result of increased wear. The braking charac-
teristics will vary depending on the substances
that get into the brakes. Clean the brakes after
driving off-road. If you notice grinding noises or a reduction in braking performance, have the
brake system checked at a qualified specialist
workshop immediately. Adapt your driving style
to the altered braking characteristics.
Driving off-road increases the possibility of dam- age to the vehicle, which may cause assemblies
or systems to fail. Adapt your driving style to the conditions of the terrain. Drive carefully. Have
vehicle damage rectified immediately at a quali-
fied specialist workshop.
Do not shift into transmission position Nwhen
driving off-road. You could lose control of the
vehicle if you attempt to brake the vehicle using
the service brake. If the gradient is too steep for your vehicle, back up in reverse gear. Driving tips

towing a trailer. By doing so, you will make use of
the braking effect of the engine. This relieves the load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
You can set a variable or permanent limit speed:
R variable for speed limits, e.g. in built-up areas
R permanent for long-term speed restrictions,
e.g. when driving with winter tyres fitted
(Y page 182)
i The speed indicated in the speedometer
may differ slightly from the limit speed stored.
Important safety notes If you fail to adapt your driving style, SPEED-

dent nor override the laws of physics. SPEED-
TRONIC cannot take into account road, weather or traffic conditions. SPEEDTRONIC 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 lane.
If there is a change of drivers, advise the new
driver of the speed stored.

WARNING
If you call up the stored speed and it is lower
than the current speed, the vehicle deceler-
ates. If you do not know the stored speed, the vehicle could decelerate unexpectedly. There
is a risk of an accident.

ted.
It is not possible to deactivate variable SPEED-
TRONIC by braking.
i The last speed stored is cleared when you
switch off the engine.
Permanent SPEEDTRONIC
You can use the on-board computer to perma-
nently limit the speed to a value between
160 km/h(e.g. for driving on winter tyres) and
the maximum design speed (Y page 247).
Shortly before the stored speed is reached, it
appears in the multifunction display.
Permanent SPEEDTRONIC remains active even
if variable SPEEDTRONIC is deactivated.
You cannot exceed the stored limit speed, even
if you depress the accelerator pedal beyond the
pressure point (kickdown). DISTRONIC PLUS
General notes DISTRONIC PLUS regulates the speed and auto-
matically helps you maintain the distance to the
vehicle detected in front. Vehicles are detected with the aid of the radar sensor system.
DISTRONIC PLUS brakes automatically so that
the set speed is not exceeded.
You must select a lower gear in good time on
long and steep downhill gradients, especially if
the vehicle is laden or towing a trailer. By doing
so, you will make use of the braking effect of the engine. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
If DISTRONIC PLUS detects that there is a risk of
a collision, you will be warned visually and
acoustically. Without your intervention, 182
Driving systemsDriving and parking

On steep uphill or downhill inclines or if there is
a malfunction, the transmission may also be
automatically shifted into position P.4MATIC
4MATIC ensures that all four wheels are perma-
nently driven. Together with ESP ®
and 4ETS, it
improves the traction of your vehicle whenever
a drive wheel spins due to insufficient grip.
If you fail to adapt your driving style, 4MATIC can
neither reduce the risk of an accident nor over-
ride the laws of physics. 4MATIC cannot take
account of road, weather and traffic conditions. 4MATIC 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
lane.
! Never tow the vehicle with one axle raised.
This may damage the transfer case. Damage
of this sort is not covered by the Mercedes-
Benz implied warranty. All wheels must
remain either on the ground or be fully raised.
Observe the instructions for towing the vehi-
cle with all wheels in full contact with the
ground.
! A function or performance test should only
be carried out on a twin-axle dynamometer.
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.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if you
use winter tyres (M+S tyres), with snow
chains if necessary. 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 brak-
ing effect on the vehicle. When driving on flat
stretches of road or on an uphill gradient, the
DSR braking effect is minimal or non-existent.
DSR controls the vehicle’s speed when it is acti- vated and the transmission is in position D,Ror
N. By accelerating or braking, you can always drive at a higher or a lower speed than that set
on the on-board computer.
Important safety notes G
WARNING
If the speed driven and the set speed deviate and you activate DSR on a slippery road sur-
face, the wheels may lose traction. This
increases the risk of skidding and having an
accident.
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 override the laws of physics. DSR cannot take account ofroad, weather and traffic conditions. DSR is only
an aid. You are responsible for the distance to
the vehicle in front, for vehicle speed, for brak-
ing in good time and for staying in lane.
You are always responsible for keeping control
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, depend-
ing on road surface and tyre conditions. Select a set speed suitable for the prevailing conditions
and when necessary, apply the brakes manually.
