Risk of accident
No further messages can be displayed if the
instrument cluster and/or the multi-function
display fails.
This means that you will not see information
about the driving situation, such as the speed,
outside temperature, warning/indicator
lamps, display messages or system failures.
The vehicle's handling characteristics may be
affected. Adjust your driving style and speed
accordingly.
Immediately consult a qualified specialist
workshop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist workshop. Coolant temperature gauge
The coolant temperature gauge is in the
instrument cluster on the left-hand side.
Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 120 †. The coolant tem-
perature may rise to the top end of the scale
at high outside temperatures and on long
uphill stretches. Speedometer with segments (vehi-
cles with 12-button luxury multi-func-
tion steering wheel*)
The segments in the speedometer indicate
which speed range is available.
Cruise control* mode:
The segments light up from the stored speed
to the maximum speed.
Variable Speedtronic* mode:

Overview of off-road driving systems
The systems which are relevant for off-road
driving are explained on the following pages:
R 4MATIC (permanent four-wheel drive), for
optimum traction
R DSR (Downhill Speed Regulation)* (vehi-
cles with Off-Road Pro engineering pack-
age*), which assists you when driving
downhill
R Off-road driving program* (vehicles with
Off-road Pro engineering package*), which
assists you when driving off-road
You will find further information about driving
off-road in the "Operation" section
(Y page 158). 4MATIC* (permanent four-wheel
drive)
4MATIC ensures that all four wheels are per-
manently driven. Together with ESP ®
and
ETS, it improves the traction of your vehicle
whenever a drive wheel spins due to insuffi-
cient grip. G
Risk of accident
4MATIC cannot reduce the risk of an accident
if you drive too fast.
If a drive wheel spins due to insufficient grip:
R only depress the accelerator pedal as far as
necessary when pulling away.
R accelerate less when driving.
R adapt your driving style to suit road and
traffic conditions.
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.
! When testing the parking brake, operate
the vehicle only briefly (for a maximum of
ten seconds) on a brake test dynamometer.
When doing this, turn the key to position
0 or 1in the ignition. Failure to do this can
cause damage to the drive train or the
brake system.
! A function or performance test should
only be carried out on a twin-axle dyna-
mometer. If you wish to operate the vehicle
on such a dynamometer, please consult a
Mercedes-Benz Service Centre in advance.
You could otherwise damage the drive train
or the brake system. DSR (Downhill Speed Regulation)*
(vehicles with the off-road engineer-
ing package*)
You will find information about driving off-
road in the "Operation" section
(Y page 158).
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 Off-road driving

with off-road engineering package*)
The off-road drive program assists you in driv-
ing off-road and when fording. The engine’s
performance characteristics and the gear-
shifting characteristics of the automatic
transmission are adapted for this purpose.
ABS, ESP ®
and ETS programs especially
adapted to off-road driving are also activated.
Do not use the off-road drive program on
roads that are snowy or icy or if you have fit-
ted your vehicle with snow chains. X

Driving systems
Overview of driving systems
The vehicle's driving systems are described
on the following pages:
R cruise control* and Speedtronic*, which
are used to control the speed of the vehicle
R Parktronic*, which assists you in parking
and manoeuvring
R reversing camera*, which assists you when
parking and manoeuvring
The ABS, BAS, adaptive brake lights, ESP ®
and EBV (electronic brake-power distribution)
driving safety systems are described in the
"Driving safety systems" section
(Y page 51). Cruise control*
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 or towing a trailer, you must
select shift range 1,2or3 in good time. 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. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 30 km/h. G
Risk of accident
Cruise control cannot take account of road
and traffic conditions. Always pay attention to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for braking in good time. G
Risk of accident
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintain a constant speed (e.g.
heavy traffic or winding roads). You could
otherwise cause an accident.
R on slippery roads. Braking or accelerating
could cause the drive wheels to lose trac-
tion and the vehicle could then skid.
R when there is poor visibility, e.g. due to fog,
heavy rain or snow

cruise control adjusts the vehicle's speed
to the last speed stored after you have fin-
ished overtaking.
i Deceleration of the vehicle by means of
the cruise control lever is assisted by auto-
matic application of the brakes.
On long downhill gradients, the automatic
transmission also shifts down.

ing
If cruise control is deactivated, you will hear
a warning tone. You see the Cruise control
off message in the multi-function display for

i The last speed stored is cleared when you
switch off the engine. Speedtronic*
Speedtronic brakes automatically so that you
do not exceed the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer, you must
select shift range 1,2or3 in good time. 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. If
you need additional braking, depress the
brake pedal repeatedly rather than continu-
ously. G
Risk of accident
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. 110 Driving systemsControls
