Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Read the information on qualified
specialist workshops: (Y page 24).Notes on breaking-in a new vehicle
Important safety notes
New and replaced brake pads and discs only
reach their optimum braking effect after
several hundred kilometers of driving.
Compensate for this by applying greater force
to the brake pedal. The first 1000 miles (1500 km)
The more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future.
R You should therefore drive at varying
vehicle and engine speeds for the first
1,000 miles (1,500 km).
R Avoid heavy loads, e.g. driving at full
throttle, during this period.
R Change gear in good time, before the
tachometer needle is 00C3of the way to the
red area of the tachometer.
R Do not manually shift to a lower gear to
brake the vehicle.
R If possible, do not depress the accelerator
pedal past the point of resistance
(kickdown).
R Only select shift ranges 3,2or 1when
driving slowly, e.g. in mountainous terrain. After 1,000 miles (1,500 km), you can
increase the engine speed gradually and bring
the vehicle to full speed.
Additional breaking-in notes for AMG
vehicles:
R Do not drive faster than 85 mph
(140 km/h) for the first 1,000 miles
(1,500 km).
R Only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
R Change gear in good time.
R Avoid driving off-road before the
differential oil change at 2,000 miles
(3,000 km).
R Ideally, for the first 1,000 miles (1,500 km),
drive in program C.
i You should also observe these breaking-
in notes if the engine or parts of the drive
train on your vehicle have been replaced.
i Always observe the respective speed
limits. AMG vehicles with rear axle locking
differential
Change the oil after a breaking-in period of
2,000 miles (3,000 km) to improve protection
of the differential. This oil change will
lengthen the service life of the differential.
Have the oil change carried out at a qualified
specialist workshop. Mercedes-Benz
recommends that you use an authorized
Mercedes-Benz Center for this purpose. Driving
Important safety notes
G
WARNING
Objects in the driver's footwell can restrict the
pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle
is jeopardized. There is a risk of an accident. 138
DrivingDriving and parking

Never activate the LOW off-road gear while
driving on a slippery road surface.
Downhill gradients !
On long and steep gradients, you must
reduce the load on the brakes by shifting
early to a lower gear. This allows you to take
advantage of the engine braking effect and
helps avoid overheating and excessive
wear of the brakes.
When you take advantage of the engine
braking effect, a drive wheel may not turn
for some time, e.g. on a slippery road
surface. This could cause damage to the
drive train. This type of damage is not
covered by the Mercedes-Benz warranty.
Heavy and light loads G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the
airflow to cool the brakes more quickly.
Wet roads If driving in heavy rain for a prolonged period
of time without braking, there may be a
delayed reaction from the brakes when
braking for the first time. This may also occur
after the vehicle has been washed. You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the
vehicle washed, brake firmly while paying
attention to the traffic conditions. This will
warm up the brake discs, thereby drying them
more quickly and protecting them against
corrosion.
Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt
residue may form on the brake discs and
brake pads. This can result in a significantly
longer braking distance.
R Brake occasionally to remove any possible
salt residue. Make sure that you do not
endanger other road users when doing so.
R Carefully depress the brake pedal and the
beginning and end of a journey.
R Maintain a greater distance to the vehicle
ahead.
Servicing the brakes !
If the brake warning lamp lights up in the
instrument cluster and you hear a warning
tone even though the parking brake has
been released, the brake fluid level may be
too low. Observe additional warning
messages in the multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked
immediately. This work should be carried
out at a qualified specialist workshop.
! A function or performance test should
only be carried out on a 2-axle
dynamometer. If you are planning to have
the vehicle tested on such a dynamometer,
contact an authorized Mercedes-Benz
Center to obtain further information first.
Otherwise, you could damage the drive
train or the brake system. 160
Driving tipsDriving and parking

R
Avoid high engine speeds – drive at an
appropriate engine speed (maximum
3,000 rpm).
R When driving down an incline, make use of
the engine's braking effect. Observe the
engine speed; do not overrev the engine.
i Further information on the maximum
engine speed: (Y page 206).
R Select a shift range appropriate to the
gradient.
R Before tackling steep downhill gradients,
select shift range 1(Ypage 150).
R Always check the brakes after driving off-
road.
i Hill start assist will aid you when pulling
away on a hill.
For more information, see "Hill start assist"
(Y page 141).
Maximum gradient-climbing capability Accelerate carefully and make sure that the
wheels do not spin when driving on steep
terrain.
i If the load on the front axle is reduced
when pulling away on a steep uphill slope,
the front wheels have a tendency to spin.
4ETS detects this and brakes the wheels
accordingly. The rear wheel torque is
increased, making it easier to drive off.
Always observe the maximum gradient
climbing ability values (Y page 351).
Hilltops When driving on an uphill gradient, reduce
pressure slightly on the accelerator
immediately before reaching the top of the hill
(do not shift the transmission to position N).
Use the vehicle's own impetus to drive over
the top of the hill. This style of driving prevents:
R
the vehicle from lifting off the ground on the
brow of a hill
R loss of traction
R the vehicle from traveling too quickly down
the other side
Driving downhill R
Before tackling steep downhill gradients,
select shift range 1(Ypage 150).
This way you use the engine's braking
effect to reduce the speed. If this is not
sufficient, brake gently. When doing so,
make sure that the vehicle is facing in the
direction of the line of fall.
R Observe the notes on driving in
mountainous terrain (Y page 168).
R Drive slowly.
R Do not drive at an angle down steep
inclines. Steer into the line of fall and drive
with the front wheels aligned straight.
Otherwise, the vehicle could slip sideways,
tip and roll over.
R Check that the brakes are working normally
after a long downhill stretch.
i The special off-road ABS setting
(Y page 61) enables repeated, brief,
precise locking of the front wheels, which
leads to the wheels digging into the loose
ground. Note that when the front wheels
are fully braked, they slide easily over the
surface of the ground, making it difficult to
steer. Driving systems
Cruise Control

WARNING
The brake pedal moves when cruise control
brakes the vehicle. A foot in the area under
the brake pedal could become trapped. The

Notes on towing a trailer
Important safety notes G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time. G
WARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The
vehicle/trailer combination could even
rollover. There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary. G
WARNING
If you install a ball coupling other than the one
delivered with the vehicle, the trailer tow hitch
and the rear axle may be overloaded. This
applies especially if the ball coupling in
question is longer or angled differently. This
could seriously impair the driving
characteristics and the trailer can come
loose. There is a risk of an accident.
Only install the ball coupling delivered with
the vehicle or a ball coupling that is designed
to meet your trailer towing requirements. Do
not modify the ball coupling or the trailer tow
hitch. G
WARNING
If the ball coupling is not installed correctly or
not secured with the bolt provided and the
corresponding spring cotter, the trailer may
come loose. There is a risk of an accident.
Always install and secure the ball coupling as
described. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter.
Please observe the manufacturer's operating
instructions for the trailer coupling if a
detachable trailer coupling is used.
You will find the applicable permissible
values, which must not be exceeded, in the
vehicle documents. You will find the values
approved by the manufacturer on the vehicle
identification plates and those for the towing
vehicle in the "Technical data" section
(Y page 342). 198
Towing a trailerDriving and parking

Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
Make sure that the following values are not
exceeded:
R the permissible trailer drawbar noseweight
R the permissible trailer load
R the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
with when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and
gradient-climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R has a larger turning circle
This could impair the handling
characteristics.
When towing a trailer, always adjust your
speed to the current road and weather
conditions. Do not exceed the maximum
permissible speed for your vehicle/trailer
combination.
General notes R
Do not exceed the legally prescribed
maximum speed for vehicle/trailer
combinations in the relevant country.
This lowers the risk of an accident.
R Only install an approved trailer coupling on
your vehicle.
Further information on availability and on
installation is available from any authorized
Mercedes-Benz Center. R
The bumpers of your vehicle are not
suitable for installing detachable trailer
couplings.
R Do not install hired trailer couplings or
other detachable trailer couplings on the
bumpers of your vehicle.
R If you do not need the ball coupling, remove
the ball coupling from the ball coupling
recess. This reduces the risk of damage to
the ball coupling.
i When towing a trailer, set the tire
pressure on the rear axle of the towing
vehicle for a maximum load; see the tire
pressure table in the fuel filler flap
(Y page 316).
You will find installation dimensions and loads
in the technical data (Y page 351).
The maximum noseweight of the trailer
drawbar on the ball coupling for up to 3
people is 562 lbs (255 kg). The maximum
permissible trailer drawbar noseweight for
more than 3 persons and the maximum load
in the trunk can be found in the trailer
drawbar noseweight table (Y page 352).
However, the actual noseweight must not
exceed the value given on the trailer tow hitch
or trailer identification plates. The lowest
weight applies.
i When towing a trailer, set the tire
pressure on the rear axle of the towing
vehicle for a maximum load; see the tire
pressure table in the fuel filler flap
(Y page 316).
Please note that when towing a trailer,
PARKTRONIC ( Ypage 189) and Blind Spot
Assist (Y page 185) are only available with
limitations, or not at all.
i On vehicles without level control, the
height of the ball coupling will alter
according to the load placed on the vehicle.
If necessary, use a trailer with a height-
adjustable drawbar. Towing a trailer
