cluster in the "At a glance" section
(Y page 26). G
Risk of accident
No further messages can be displayed if
there is a malfunction in the instrument
cluster and/or the multi-function display.
This

means that you will not see information
about the driving situation, such as the
speed, outside temperature, warning/indi-
cator lamps, display messages or system
failures. The vehicle's handling character-
istics may be affected. Adjust your driving
style and speed accordingly.
Immediately consult a qualified specialist
workshop which has the necessary special-
ist knowledge and tools to carry out the
work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz
Service Centre for this purpose. In particu-
lar, work relevant to safety or on safety-
related systems must be carried out at a
qualified specialist workshop. Controls

Storing and maintaining the current
speed You can store the current speed if you are
driving
faster than 30 km/h and ESP ®
is acti-
vated ( Y page 59).
X Accelerate the vehicle to the desired
speed.
X Briefly press the cruise control lever up
1 or down 4.
X Remove your foot from the accelerator
pedal.
Cruise control is activated. The vehicle
automatically maintains the stored speed.
i Cruise
control may be unable to maintain
the stored speed on uphill gradients. The
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by
automatically applying the brakes.
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 you
or others.
X Briefly pull the cruise control lever towards
you 3.
X Remove your foot from the accelerator
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 up 1 for a
higher

speed or down 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.
On long downhill gradients, the automatic
transmission shifts down as a further meas-
ure.
Making fine adjustments in 1 km/h
increments X
Briefly press the cruise control lever up
1 for a higher speed or down 4 for a
lower speed.

Towing and tow-starting
293Towing and tow-starting
Points to remember
G
Risk of accident
If you tow the vehicle, you must use a rigid
towing bar if:
R the engine is not running
R there is a brake system malfunction
R the voltage supply or the vehicle's elec-
trical system is damaged
There
is no power assistance for the steer-
ing when the engine is not running. G
Risk of accident
The vehicle is braked when HOLD is activa-
ted.
Therefore, deactivate HOLD if the vehi-
cle is to be towed.
If you tow or tow-start another vehicle, its
weight must not exceed the maximum per-
missible gross vehicle weight of your vehi-
cle.
It is better to have the vehicle transported
than to have it towed.
When towing, observe the legal requirements
in all countries concerned. !
When towing, pull away slowly and with-
out

jerking. If the tractive power is too high,
the vehicles could be damaged. Do not use
the towing eye for recovery.
! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/h must
not be exceeded.
With towing distances over 50 km, the
entire vehicle needs to be lifted up and
transported.
! Only secure the tow cable or towing bar
to the towing eyes. You may otherwise
damage the vehicle.
R Vehicles with an automatic transmission
must not be tow-started.
R If the engine does not start, try jump-start-
ing it (Y page 291).
R If it is not possible to jump-start the vehicle,
have it towed to the nearest qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
R If the vehicle has suffered transmission
damage, only tow it with the propeller shaft
disconnected.
R The selector lever must be in position N on
vehicles with automatic transmission. R
If you are towing the vehicle over a consid-
erable distance, this may only be done with
the rear axle raised.
R The ignition must be switched off if you are
towing the vehicle with the front/rear axle
raised. Intervention by ESP ®
could other-
wise damage the brake system.
R Before towing the vehicle, make sure that
the battery is connected and charged. Oth-
erwise:
-You cannot switch on the ignition
- You cannot move the selector lever to N
- You have no support when braking
i Switch off the automatic locking feature
before the vehicle is towed (Y page 127).
You could otherwise be locked out when
pushing or towing the vehicle. Practical advice
