cluster goes out. Switching off the engine
G
Risk of accident
If the engine is not running, there is no power
assistance for the steering and brakes. Steer-
ing and braking will then require significantly
greater effort.
As a result, you might lose control of the vehi-
cle, cause an accident and injure yourself and
others.
Do not switch off the engine while driving.
X Move the selector lever to P.
X Turn the key to position 0(Y page 61) in
the ignition lock and remove it.
The immobiliser is activated.
i The key can only be removed when the
selector lever is in position P.Transmission
Notes on the transmission
G
Risk of accident
The movement of the pedals must not be
impaired in any way. Do not keep any objects
in the driver's footwell. Make sure that floor-
mats or carpets are correctly secured and
that there is sufficient clearance for the ped-
als.
Do not place several floormats on top of one
another. 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. This could cause you
to lose control of your vehicle and cause an
accident.

Instrument cluster
Points to remember
You will find an illustration of the instrument
cluster in the "At a glance" section.
Vehicles with a multi-function steering wheel
(4 buttons) (Y page 24)
Vehicles with a luxury multi-function steering
wheel* (12 buttons) (Y page 26)G
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:
The segments light up from the start of the
scale to the selected limit speed. Rev counter
The red band in the rev counter indicates the
engine's overrevving range. The fuel supply is
interrupted to protect the engine when the
red band is reached.
! Do not drive in the overrevving range.
Doing so will damage the engine. Outside temperature display
G
Risk of accident
When the temperature displayed is just above
freezing point, the road surface may be icy,
especially in wooded areas or on bridges. The
vehicle could skid if you fail to adapt your
driving style. Always adapt your driving style
and drive at a speed to suit the prevailing
weather conditions.
Changes in the outside temperature are dis-
played after a short delay. 90 Instrument clusterCont

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.
Making adjustments in 1 km/hincre-
ments X
Briefly press the cruise control lever to the
pressure point, up :for a higher speed or
down ?for a lower speed.

ments X
Briefly press the cruise control lever
beyond the pressure point up :for a
higher speed or down ?for a lower speed.

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
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
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

the 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 driving and traffic situation. Other-
wise, sudden braking could endanger you or
others.

beyond the pressure point (kickdown), but
only if your current speed does not differ by
more than 20 km/h from the stored speed.
You will hear a warning tone if this is the case. G
Risk of accident
It is not possible to deactivate variable Speed-
tronic by braking.
i The last speed stored is cleared when you
switch off the engine.
Permanent Speedtronic (vehicles with
the luxury multi-function steering
wheel*, 12 buttons) i
Permanent Speedtronic is only available
in certain countries.
You can use the on-board computer to limit
the speed permanently to a value between
160 km/h (e.g. for driving with winter tyres)
and the maximum speed.
Just before the stored speed is reached, it
appears in the multi-function display.
You cannot exceed the stored limit speed,
even if you depress the accelerator pedal
beyond the pressure point (kickdown). 112 Driving systemsControls
