6 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 th e
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 windin g
roads). You could otherwise cause an
accident.
R on slippery roads. Braking or accelerat-
ing could cause the drive wheels to lose
traction and the vehicle could then skid.
R when there is poor visibility, e.g. due to
fog, heavy rain or snow

Selecting cruise control X
Check whether LIM indicator lamp 2is off .
If it is off, cruise control is already selected.
If it is not, press the cruise control lever in
the direction of arrow 5.
LIM indicator lamp 2in the cruise control
lever is off. Cruise control is selected.
Storing and maintaining the current
speed You can store the current speed if you are
driving faster than 30 km/h.
X Accelerate the vehicle to the desired
speed.
X Press the cruise control lever briefly to the
pressure point, either upwards 1or down-
wards 4.
X Remove your foot from the accelerato r
pedal.
Cruise control is activated. The vehicle
automatically maintains the stored speed.
i Cruise control may be unable to maintai n
the stored speed on uphill gradients. Th e
stored speed is resumed when the gradient
evens out. Cruise control maintains the stored speed on downhill gradients by
automatically applying the brakes.
Vehicles with manual transmission:
R Always drive at adequate but not exces-
sive engine speeds .
R Change gear in good time.
R If possible, do not change down several
gears at a time.
Selecting the current or last stored
speed G
Risk of accident
Only select a stored speed if you know what
that speed is and whether it is suitable for
the current situation. Otherwise, sudden
acceleration or braking could endanger yo u
or others.
X Pull the cruise control lever briefly towards
you 3.
X Remove your foot from the accelerato r
pedal.
Cruise control is activated and adjusts the
vehicle's speed to the last speed stored. Setting a speed X
Press the cruise control lever beyond pres-
sure point 1for a higher speed or dow n
4 for a lower speed.
X Keep the cruise control lever pressed until
the desired speed is reached .
X Release the cruise control lever.
The new speed is stored.
i Cruise control is not deactivated if you
depress the accelerator pedal. For exam-
ple, if you accelerate briefly to overtake ,
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 .
Vehicles with automatic transmission*:
On long downhill gradients, the automatic
transmission shifts down as a further meas-
ure. Controls

If cruise control is deactivated, you will hear
a warning tone. You see the Cruise control
off message in the multi-function display for
approximately five seconds.
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
shift to a lower gear in good time or select
shift range 1,2 or 3in vehicles with automatic
transmission*. In this way 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 continuously. G
Risk of accident
Never depress the brake pedal continu -
ously 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. Thi s
could cause the drive wheels to lose thei r
grip and the vehicle could skid. Controls

suddenly to a speed above that stored as
the limit speed, otherwise you could cause
an accident.

Downhill gradient
sOn long and steep downhill stretches, espe-
cially if the vehicle is laden or towing a trailer,
you must shift to a lower gear in good time or,
on vehicles with automatic transmission*,
select shift range 1,2 or 3.
i This also applies if you have activated
cruise control* or Speedtronic*.
This uses the braking effect of the engine and
you will not have to brake to such an exten t
to maintain the same speed. This 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 continuously.
Heavy and light loads 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 air-
flow to cool the brakes more quickly. G
Risk of accident
Never depress the brake pedal continu -
ously 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.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet roads If you drive for a long time in the rain without
braking, there may be a delayed reaction
when you first brake and you will have to
depress the pedal harder.
You must therefore maintain a greater dis-
tance from the vehicle in front.
Brake firmly after driving on a wet road. Thi
s
way the brake discs will become warm, dryin g
more quickly, which will protect them against
corrosion. Limited braking performance on salted
roads G
Risk of accident
The layer of salt on the brake discs and the
brake linings may cause a delay in the brak-
ing effect, resulting in a significantly longer
braking distance, which could lead to an
accident.
To avoid this danger, you should:
R occasionally brake carefully when you
are driving on salted roads, so that any
layer of salt that may have started to
build up on the brake discs and the brake
linings is removed without putting other
road users at risk.
R maintain a greater distance to the vehicl e
ahead and drive with particular car e
R carefully apply the brakes at the end of a
trip and immediately after commencing a
new trip, so that salt residues ar e
removed from the brake disc.
New brake linings For safety reasons, Mercedes-Benz recom
-
mends that you have only brake pads/linings
fitted to your vehicle that have been approved Operation

R
Maintain a greater distance from the vehi-
cle in front than when driving without a
trailer.
R Avoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from a standstill refer to sea
level. When driving in mountainous areas,
note that the power output of the engine
and with it its gradient-climbing capability
decrease with increasing altitude.
If the trailer swings from side to side:
X Do not accelerate.
X Do not counter-steer.
X Brake if necessary. G
Risk of accident
On no account should you attempt to dra w
the vehicle/trailer combination out by
increasing speed. Folding in the ball couplin

i Fold in the ball coupling when you are not
using the trailer tow hitch . G
Risk of injury
Make sure that no persons or animals are

Otherwise, they could be injured .
