Driving systems
Introduction
This section describes the following driving
systems of your vehicle:
R Cruise control
R Distronic
R Distance warning function (only available
with Distronic)
R Hill-start assist system
R Downhill Speed Regulation (DSR)
R Off-road driving program
R Air suspension program (Adaptive
Damping System (ADS) and vehicle level
control)
R All-wheel drive (4MATIC)
R Parktronic system
R Rear view camera
The driving safety systems ABS, BAS, EBP,
ESP ®
and 4-ETS are described in the “Safety
and security” section ( Y page 61).
Cruise control
The cruise control maintains the speed you
set for your vehicle automatically.
The use of the cruise control is recommended
for driving at a constant speed for extended
periods of time.
The currently set speed or last set speed
(“Resume” function) appears in the status
indicator of the multifunction display:
R USA only: e.g. Cruise 55 Miles
R Canada only: e.g. ¯ 90 Km/h
i The cruise control should not be activated
during off-road driving.GWarning!
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.

Reduce set speed:XBriefly press the cruise control lever down
past the resistance point in direction of
arrow ;.
XRelease the cruise control lever.
The vehicle speed decreases in increments
of 5 mph (Canada: 10 km/h).
Each time the set speed is changed, DSR
will appear in the multifunction display and
the changed set speed is shown.
The new speed is set and the vehicle will
accelerate or decelerate. Keep in mind that
it may take a brief moment until the vehicle
has reached the new set speed.
The set speed is canceled when the DSR is
switched off. If the DSR is switched on again,
the DSR will use the programmed default
speed (Y page 138).
Off-road driving program
The off-road driving program is designed to
assist the driver when driving off-road in
terrain and crossing water. The off-road
driving program adjusts the engine power and
shifting of the automatic transmission to be
more suitable for the off-road use of the
vehicle. In addition, the ABS, ESP®, and 4-ETS
designed for off-road use are automatically
activated.
In the following situations you should switch
to the off-road driving program:
Rduring off-road driving
Rwhen crossing water (Y page 251)
Rwhen towing up or down on steep gradients

Air suspension program
The system lets you select the chassis and
suspension setup. The chassis and
suspension setup adjusts the damping
behavior and the ride height for your vehicle.
The system consists of two components. The
Adaptive Damping System (ADS)
(Y page 156) and the vehicle level control
(Y page 156).

Tread
The portion of a tire that comes into contact
with the road.
Treadwear indicators
Narrow bands, sometimes called “wear bars”
that show across the tread of a tire when only
1 / 16 in (1.6 mm) of tread remains.
TWR (Tongue Weight Rating)
Maximum permissible weight on trailer
tongue.
Uniform Tire Quality Grading Standards
A tire information system that provides
consumers with ratings for a tire’s traction,
temperature and treadwear. Ratings are
determined by tire manufacturers using U.S.
government testing procedures. The ratings
are molded into the sidewall of the tire.
Vehicle maximum load on the tire
Load on an individual tire that is determined
by distributing to each axle its share of the
maximum loaded vehicle weight and dividing
it by two.
Winter driving
General information
Have your vehicle winterized at an authorized
Mercedes-Benz Center.
i Vehicles with diesel engine:
Do not cover the radiator, for example with
a winter front. Otherwise the readings of
the on-board diagnostic system may be
inaccurate. Some of theses readings are
required by law and must be accurate at all
times.
Winter tiresGWarning!
Winter tires with a tread depth of less than
1 / 6 in (4 mm) must be replaced. They are no
longer suitable for winter operation.
GWarning!
If you use your spare wheel when winter tires
are fitted on the other wheels, be aware that
the difference in tire characteristics may very
well impair turning stability and that overall
driving stability may be reduced. Adapt your
driving style accordingly.
Have the spare wheel replaced by a regular
road wheel with a winter tire at the nearest
authorized Mercedes-Benz Center.
Always use winter tires at temperatures
below 45‡ (7†) and whenever wintry road
conditions prevail. Not all M+S rated tires
provide special winter performance. Make
sure the tires you use show the mountain/
snowflake imarking on the tire sidewall.
These tires meet specific snow traction
performance requirements of the Rubber
Manufacturers Association (RMA) and the
Rubber Association of Canada (RAC) and
have been designed specifically for use in
snow conditions. Use of winter tires is the
only way to achieve the maximum
effectiveness of your vehicle’s driving safety
systems such as the ABS and the ESP ®
in
winter operation.
For safe handling, make sure all mounted
winter tires are of the same make and have
the same tread design.
For information on winter tires for your
vehicle model, see the “Technical data”
section ( Y page 352).
Always observe the speed rating of the winter
tires installed on your vehicle.

After installing winter tires:XCheck the tire inflation pressure and adjust
it if necessary ( Y page 221).XRestart the tire pressure loss warning
system ( Y page 222) or the Advanced Tire
Pressure Monitoring System (Y page 223).
Snow chains
! Vehicles with Adaptive Damping System
(ADS):
When driving with snow chains, do not
select SPORT mode as this may result in
damage to your vehicle.
! Some tire sizes do not leave adequate
clearance for snow chains. To help avoid
serious damage to your vehicle or tires,
make sure the use of snow chains is
permissible as specified in the “Technical
data” section of this Operator’s Manual.
Snow chains should only be driven on snow-
covered roads at speeds not to exceed
30 mph (50 km/h). Remove chains as soon
as possible when driving on roads without
snow.
Observe the following guidelines when using
snow chains:
R Use of snow chains is not permissible with
all wheel/tire combinations ( Y page 352).
R Use snow chains in pairs and on rear
wheels only. Follow the manufacturer’s
mounting instructions.
! If snow chains are mounted to the front
wheels, they may scrape against the body
or axle components. The tires or the vehicle
could be damaged as a result.
R Only use snow chains that are approved by
Mercedes-Benz. Any authorized Mercedes-
Benz Center will be glad to advise you on
this subject.
R Use of snow chains may be prohibited
depending on location. Always check local
and state laws before installing snow
chains.
R Do not use snow chains on the spare wheel.
i When driving with snow chains, you may
wish to switch off the ESP ®
(Y page 63)
before setting the vehicle in motion. This
will improve the vehicle’s traction.
Winter driving instructions
GWarning!
If the vehicle becomes stuck in snow, make
sure 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 interior
resulting in unconsciousness and death.
To assure sufficient fresh air ventilation, open
a window slightly on the side of the vehicle
not facing the wind.
GWarning!
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
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.
GWarning!
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.
The most important rule for slippery or icy
roads is to drive sensibly and to avoid abrupt
acceleration, braking and steering
maneuvers. Do not use the cruise control
system under such conditions.
When the vehicle is in danger of skidding, shift
the automatic transmission to neutral

For more information, see “Driving through
water” ( Y page 251).
Off-road driving
GWarning!
Do not load items on the basic carrier bars. It
may cause instability during some maneuvers
which could result in an accident.
Drive slowly in unknown terrain. This will
make it easier to recognize unexpected
obstacles and avoid damage to the vehicle.
To help avoid the vehicle rolling over, never
turn it around on steep inclines. If the vehicle
cannot complete the attempted climb, back it
down in reverse gear.
Do not drive along the side of a slope. The
vehicle might otherwise rollover. If in doing so
the vehicle begins to show a tendency to roll,
immediately steer into a line of gravity
(straight up or downhill).
Never let the vehicle roll backwards in idle.
You may lose control of the vehicle if you use
only the service brake. For information on
driving downhill, see “Driving downhill”.
GWarning!
Sand, dirt, mud and other material having
friction property can cause exceptional wear
and tear as well as brake failure.
Have the brakes checked for dirt build-up and
cleaned. There is otherwise a risk that full
braking power may not be available in an
emergency.
GWarning!
Vehicles with air suspension program: Please
be aware that by raising the vehicle level, the
center of gravity also rises. Therefore, always
ensure that the vehicle level is as low as
possible. With higher ride height the ESP ®
may activate earlier in certain situations.
Read this chapter carefully before you begin
off-road travel.
Familiarize yourself with the vehicle
characteristics and gear changing before you
attempt any difficult terrain off-road driving.
We recommend that you start out with easy
off-road travel.
Special driving features for off-road
driving
The following driving features are available for
specific kind of operation:
R Off-road ABS ( Y page 63)
R Off-road ESP ®
(Y page 65)
R Off-road 4-ETS ( Y page 64)
R Hill-start assist system ( Y page 113)
R Downhill Speed Regulation (DSR)

R Off-road driving program ( Y page 155)
R Air suspension program ( Y page 155)
Off-road driving rules
R Engage the off-road driving program
( Y page 155) before driving under off-road
conditions.
R Vehicles with air suspension program:
Make sure you select a vehicle level
( Y page 156) appropriate to the
topographical conditions. Always make
sure the vehicle has enough ground
clearance.
R Fasten items being carried as securely as
possible ( Y page 186).
R Always navigate gradients with the engine
on and with the transmission engaged in a
gear. Switch on the DSR ( Y page 152) to
help maintain a preset speed.

The 4-ETS recognizes the situation and
limits the torque for the front wheels by
braking them.
Simultaneously the torque for the rear
wheels is increased.
Driving across a hilltop
Decelerate just ahead of a hilltop (do not shift
automatic transmission into neutral position
N), to prevent the vehicle from speeding up
too much after climbing a hill.
Use the momentum of the vehicle to drive
across the hilltop.
After climbing a hill, driving in this manner
prevents the vehicle from:
Rlosing ground contact when cresting hills
Rlosing its forward momentum
Rspeeding up too much after climbing the hill
Driving downhill
RDrive slowly.
RDo not drive at an angle to the incline. Steer
into the line of gravity and drive with the
front wheels pointing straight downhill.
Otherwise, the vehicle may slide sideways
off the path and roll over.
RShift automatic transmission into gear
range 1 (Y page 113).
ROn steep inclines, use the Downhill Speed
Regulation (Y page 152).
RUtilize the engine’s braking power to
reduce vehicle speed.
If this is insufficient, apply the brakes
gently. Make sure the vehicle is moving in
the line of gravity.
RCheck the brakes after a lengthy
downgrade drive.
iThe special Off-road ABS (Y page 63)
setting allows for precise and brief
(cyclical) blocking of the front wheels,
permitting them to dig into loose ground.
Remember that, when stopped, the front
wheels slide across a surface and thus lose
their ability to steer the vehicle.

RBefore driving through water, determine its
depth.
! The water depth must not exceed the
respective value listed in the table. The
ground under the water might not be firm
which could result the water being deeper
than expected when driving the vehicle
through it. Please note that the water level
is correspondingly lower for flowing water.
RVehicles with air suspension program:
Select the highest vehicle level possible
(Y page 156).
RSwitch to off-road driving program
