Risk of accident
Do not put any objects in the driver's footwell.
If you use a floormat or carpet in the driver's
footwell, make sure that they are correctly
secured and that there is sufficient clearance
for the pedals.
Do not place several floormats on top of one
another.
Otherwise, the objects or floormats could get
between the pedals in the event of sudden
braking or acceleration. You may then no lon-
ger be able to brake, change gear or acceler-
ate as intended. This may result in an accident
and injury. G
Risk of poisoning
Never leave the engine running in enclosed
spaces. The exhaust gases contain carbon
monoxide. Inhaling exhaust fumes consti-
tutes a health hazard and could lead to loss
of consciousness or even death.

i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill start assist Hill start assist helps you when pulling away
on uphill gradients. It holds the vehicle for a
short time after you have removed your foot
from the brake pedal. This gives you enough
time to move your foot from the brake pedal
to the accelerator pedal and depress it before
the vehicle begins to roll. G
Risk of accident
Never leave the vehicle when it is held by hill
start assist. After approximately one second,
hill start assist will no longer brake your vehi-
cle and it could roll away.

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

gradient, the DSR braking effect is minimal or
non-existent. G
Risk of accident
DSR is only an aid designed to assist you when
driving downhill. You are responsible for keep-
ing control of the vehicle and for assessing
whether the downhill gradient can be man-
aged.
When activating DSR the vehicle may brake
suddenly due to DSR intervening. This is
dependent on the downhill gradient and the
difference between the current speed and the
speed set. DSR may not always be able to
keep to the set speed, depending on road sur-
face and tyre conditions. You could lose con-
trol of the vehicle and cause an accident.
Select a set speed suitable for the prevailing
conditions and when necessary, apply the
brakes manually.
DSR controls the vehicle’s speed in the D,R
and Nselector lever positions. You can drive
at a higher or a lower speed than that set on
the on-board computer at any time by accel-
erating or braking. G
Risk of accident
If you depress the accelerator pedal with DSR
activated, then the set speed can be excee-
ded. Drive downhill with special care and
always keep in mind that DSR brakes the vehi-
cle as soon as you remove your foot from the
accelerator pedal. The vehicle may be heavily
braked by DSR depending on the gradient and
the difference between the vehicle's road
speed and the set speed. You could lose con-
trol of the vehicle and cause an accident.

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
