\3 Driving safety systemsIn this section, you will find information
about the following driving safety systems:
\4ABS (A
ntilock B
rake S
ystem)
\4BAS (B
rake As
sist)
\4ESP
® (E
lectronic S
tability P
rogram)
\4ASR (acceleration skid control)
\4EBV (electronic brake force distribu-
tion)ABS regulates the brake pressure in such a
way that the wheels do not lock when you
brake. This allows you to continue steering
when braking.
ABS works from a speed of about 3 mph
(5 km/h) upwards, regardless of road sur-
face conditions.
ABS works on slippery surfaces, even
when you only brake gently.
There is a malfunction if the - indicator
lamp is permanently lit while the engine is
running (\2page 271).
Despite this, the normal driving and brak-
ing functions remain available.
iThe maximum effect of ABS, BAS,
ESP
®, ASR and EBV can only be
achieved if you:
\4always drive with the correct tire
pressures adjusted according to
the load (\2page 210)
\4use winter tires (M+S tires) in win-
try conditions, with snow chains if
necessary
Warning
G
There is an increased risk of an accident if
you:
\4drive too fast, in particular when corner-
ing and on a wet or slippery road surface
\4drive too close to the vehicle in front
The driving safety systems described in this
section cannot reduce this risk and are un-
able to override the laws of physics.
Always adapt your driving style to the pre-
vailing road and weather conditions, and
maintain an adequately safe distance from
other road users as well as any obstacles on
the road.iOnly use wheels with the recommend-
ed tire sizes (\2page 367), otherwise
the driving safety systems will not work
correctly.
Antilock Brake System (ABS)Warning
G
Do not depress the brake pedal several
times in quick succession (pumping). De-
press the brake firmly and evenly. Pumping
the brake pedal may reduce the braking ef-
fect.

Braking
If ABS intervenes during braking, you will
feel the steering wheel vibrate gently and
the brake pedal pulsate.
If ABS intervenes:
\1Continue to depress the brake pedal
firmly until the braking situation is over.
For full brake application:
\1Depress the brake pedal with maxi-
mum force.Brake Assist operates in emergency brak-
ing situations. If you depress the brake
pedal quickly, BAS automatically increases
the brake pressure, thereby reducing the
stopping distance.
\1Keep the brake pedal firmly depressed
until the emergency braking situation is
over.
ABS prevents the wheels from locking.
When you release the brake pedal, the
brakes will work as normal again. BAS is
deactivated.
Vehicles without steering wheel buttons:
There is a malfunction if thek indicator
lamp is permanently lit while the engine is
running (\2page 270).ESP
® monitors driving stability and detects
a tendency of the vehicle to understeer or
oversteer (skidding). ESP
® stabilizes the
vehicle by braking individual wheels, limit-
ing the engine power output, and greatly
assists you when driving on wet or slippery
road surfaces. ESP
® also stabilizes the ve-
hicle when braking.
When ESP
® intervenes, thev warning
lamp in the speedometer flashes.
Warning
G
Always adapt your driving style to the pre-
vailing road and weather conditions, and
maintain an adequately safe distance from
other road users as well as any obstacles on
the road.
If ABS malfunctions, the wheels could lock
when you brake. This means that the steer-
ability of the vehicle is restricted during
braking and the stopping distance may in-
crease. If ABS is deactivated due to a mal-
function, BAS is also deactivated.Brake Assist (BAS)
Warning
G
If BAS malfunctions, the brake system is still
available with the full brake boosting effect.
In an emergency braking situation, however,
the braking force will not be additionally
boosted automatically and the stopping dis-
tance may increase.Electronic Stability Program (ESP
®)

Activating/deactivating ASR
ASR is automatically activated as soon as
the engine is switched on.
It may be best to deactivate ASR in the fol-
lowing situations:
\4if snow chains are being used
\4in deep snow
\4on sand or gravel
If you deactivate ASR:
\4the engine’s torque is then no longer
limited and the drive wheels could spin;
the spinning wheels produce a cutting
effect for better traction
\4traction control still intervenes by brak-
ing if one drive wheel reaches its grip
limit, for example if the surface under
one side of the vehicle is slippery. The
wheel is then braked to increase trac-
tion in this situation.
\4ESP
® still intervenes to stabilize the ve-
hicleThe ASR switch is located on the center
console.
1To deactivate/activate ASR
\1To switch off: press upper section1
of the switch.
The v warning lamp in the speed-
ometer lights up.
\1To switch on: press upper section1
of the switch again.
Thev warning lamp in the speed-
ometer goes out.
Warning
G
ESP
® remains active despite ASR having
been deactivated and carries out braking in-
terventions if this is necessary to improve
driving stability. Thev warning lamp
flashes.
If ASR is deactivated, there is an increased
risk that the brake system of your vehicle
could overheat and be damaged when sub-
jected to high loads for a long period of time.
A hot brake system also increases the stop-
ping distance.
For this reason, only deactivate ASR when it
is absolutely necessary.

\3 Driving systemsDriving systems which may form part of
your vehicle are described on the following
pages:
\4Cruise control* (\2page 147), which
you can use to control the speed of
your vehicle
\4Parktronic system*, which is an aid for
parking and maneuvering
(\2page 150)
\4Reverse warning feature*, which helps
you ensure the safety of other road us-
ers (\2page 153)
The ABS, BAS, ESP
®, ASR and EBV driving
safety systems are described in the "Safe-
ty and Security" section (\2page 23).Cruise control maintains the speed of the
vehicle for you.
Use cruise control if road and traffic condi-
tions make it appropriate to maintain a
steady speed for a prolonged period. You
can store any road speed above 20 mph
(30 km/h).
Cruise control*iThe increments for setting speed and
the threshold values for switching on or
automatically switching off cruise con-
trol depend on the digital speedometer
setting, mph or km/h (\2page 99).Warning
G
The cruise control function cannot take ac-
count of road and traffic conditions.
Always pay attention to road and traffic
conditions, even when cruise control is acti-
vated.
Cruise control is only an aid designed to as-
sist driving. You are responsible for the vehi-
cle’s speed and for braking in good time.
If there is a change of drivers, advise the
new driver of the cruising speed that is
stored.Warning
G
Do not use cruise control:
\4if road and traffic conditions do not per-
mit a constant driving speed to be main-
tained (e.g. heavy traffic or winding
roads). You could otherwise cause an
accident.
\4on slippery roads. The drive wheels may
lose their grip when braking or acceler-
ating and the vehicle could skid
\4when visibility is poor, e.g. in fog, heavy
rain or snow

Setting the speed
\1Briefly press the cruise control lever
upward1 to increase the speed or
downward3 to reduce the speed.
The last speed stored is increased or
decreased in 1 mph increments
(1 km/h increments).
or
\1Press and hold the cruise control lever
up1 or down3 until the desired
speed has been reached.\1Release the cruise control lever.
The current speed is stored.
Deactivating cruise control
There are various ways of deactivating
cruise control:
\1Briefly press cruise control lever
forward4.
or
\1Apply the brakes.
The last speed set remains stored.Warning
G
The rate at which you increase the speed in
1 mph increments (1 km/h increments) may
be faster than your vehicle is able to accel-
erate. Your vehicle may then continue to ac-
celerate up to the newly set speed even
after you have released the cruise control le-
ver.
Only increase the speed if the current situa-
tion is appropriate to do so. Sudden acceler-
ation could otherwise endanger you and
others.
iCruise control is not deactivated if you
depress the accelerator pedal. If you ac-
celerate briefly to overtake, for exam-
ple, cruise control adjusts the vehicle’s
speed to the last speed stored after you
have finished overtaking.iThe last speed stored is cleared when
you switch off the engine.
iCruise control is automatically deacti-
vated if:
\4you are braking

\1Always attach the lashing net or tarps
to all available lashing points. While do-
ing so, make sure that the mounting
hooks cannot open unintentionally.Warning
G
Do not carry out any modifications or repairs
to the lashing points, the lashing eyes or the
lashing materials. The load or the lashing
points could accidentally come loose and
cause serious injury to you or others as well
as damage to property.
Distribute loads evenly between the lashing
points or lashing eyes.
Observe the loading guidelines.iLoose loads should be secured with an
approved lashing net or tarp.
!
CAUTION
Observe the data on the maximum
load-bearing capacity of the individual
lashing points
(\2
page 371).
During full-braking applications, for ex-
ample, forces can be involved that are
much greater than the weight force of
the load.
Always use several lashing points in or-
der to distribute force absorption, and
make sure that the lashing points have
an equal load.
iIf your vehicle has load rails in the floor,
you should position locking rods imme-
diately in front of and behind the load.
The locking rods absorb possible shift-
ing forces directly.
Warning
G
If you tension the lashing straps between
the side walls or between a side wall and the
load compartment floor, the permissible
load for the lashing rails, lashing points or
lashing eyes could be exceeded in the event
of strong braking, sudden changes of direc-
tion or an accident.
The load would no longer be secured, which
could result in serious injuries caused by the
load slipping.
For this reason, do not tension a lashing
strap between the side walls or between a
side wall and the load compartment floor.
Only locking bars or rods may be installed
between the load rails near the side walls.
Observe the operating instructions issued
by the locking bar or locking rod manufac-
turer.

You can disconnect the current to all your
vehicle’s consumers using the battery
isolating switch. This will prevent uncon-
trolled battery discharge caused by quies-
cent current consumption.The battery isolating switch is to the right
of the accelerator pedal in the driver’s foot-
well.

are cut off from the electrical circuit.Warning
G
If the vehicle is equipped with an auxiliary
battery in the engine compartment, it is nec-
essary to disconnect both batteries when
working on the vehicle electrical system.
Only then is the electrical system fully dis-
connected from the power supply.iOnly disconnect the vehicle electrical
system from the power supply using
the battery isolating switch if the vehi-
cle is to be parked up for a long period
or when this is absolutely necessary.
After the power supply is switched on,
you must reset the electric sliding door
(\2page 57).
