A full view illustration of the instrument
cluster can be found in the “At a glance”
section of this manual (
page 28).
The instrument cluster is activated when
you:

open a door

switch on the ignition (page 344)

switch on the exterior lamps
The language setting for the multifunction
display can be changed via COMAND

Coolant temperature gauge
The coolant temperature gauge is on the
left side in the instrument cluster
(
page 28).
Warning!G
No messages will be displayed if either the
instrument cluster or the multifunction dis-
play is inoperative.
As a result, you will not be able to see infor-
mation about your driving conditions, such
as speed or outside temperature, warning/
indicator lamps, malfunction/warning mes-
sages or the failure of any systems. Driving
characteristics may be impaired.
If you must continue to drive, please do so
with added caution. Contact an authorized
Mercedes-Benz Center as soon as possible.
iThe instrument cluster illumination is
dimmed or brightened automatically to suit am-
bient light conditions.
The instrument cluster illumination will also be
adjusted automatically when you switch on the
vehicle’s exterior lamps.
Warning!G

Driving when your engine is overheated
can cause some fluids which may have
leaked into the engine compartment to
catch fire. You could be seriously
burned.

Steam from an overheated engine can
cause serious burns and can occur just
by opening the hood. Stay away from
the engine if you see or hear steam com-
ing from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out

Tachometer
The red marking on the tachometer de-
notes excessive engine speed.To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
Outside temperature indicator
The outside temperature indicator is on
the bottom left-hand side of the instru-
ment cluster (
page 28).
The temperature sensor is located in the
front bumper area. Due to its location, the
sensor can be affected by road or engine
heat during idling or slow driving. There-
fore, the accuracy of the displayed temper-ature can only be verified by comparison to
a thermometer placed next to the sensor,
not by comparison to external displays
(e.g. bank signs, etc.).
When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.
Fuel gauge
The fuel gauge is on the left-hand side of
the instrument cluster (
page 28). Once
the fuel level has fallen below the reserve
mark, the yellow segment indicator for the
fuel reserve comes on (
page 605).
of the vehicle and do not stand near the ve-
hicle until the engine has cooled down.
!Excessive coolant temperature triggers a
warning in the multifunction display
(
page 646).
The engine should not be operated with the cool-
ant temperature above 248°F (120°C), i.e. in
the red zone of the coolant temperature gauge.
Doing so may cause serious engine damage
which is not covered by the Mercedes-Benz Lim-
ited Warranty.
iDuring severe operating conditions,
e.g. stop-and-go traffic, the coolant temperature
may rise close to 248°F (120°C), i.e. close to
the red zone of the temperature gauge.
!Avoid driving at excessive engine speeds, as
it may result in serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
Warning!G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.

In the following cases you cannot activate
the cruise control:

when you brake

the vehicle is secured with the elec-
tronic parking brake

when the automatic transmission is set
to positionP, R, or N

when ESP® is switched off
Setting current speed
Accelerate or decelerate to the desired
speed.
Briefly lift the cruise control lever in
direction of arrow1 or depress in
direction of arrow2.
The current speed is set.
Warning!G
The cruise control brakes automatically so
that the set speed is not exceeded. The
brake pedal depresses when the cruise con-
trol engages the brakes.
Keep driver’s foot area clear at all times, in-
cluding the area under the brake pedal. Ob-
jects stored in this area may impair pedal
movement which could interfere with the
braking ability of the cruise control system.
Do not place your foot under the brake pedal
– your foot could become caught.
Keep in mind that the cruise control is a con-
venience system designed to assist the driv-
er during vehicle operation. The driver is and
must always remain responsible for the ve-
hicle’s speed and for safe brake operation.
iThe vehicle speed displayed in the speedom-
eter can briefly vary from the speed setting for
the cruise control system.

The last set speed appears in the
multifunction display for approxi-
mately 5 seconds.

The corresponding speedometer
segments from the selected speed
to the vehicle maximum speed in
the multifunction display are illumi-

iOn uphill grades, the cruise control may not
be able to maintain the set speed. Once the
grade eases, the set speed will be resumed.
On downhill grades, the cruise control maintains
the set speed by braking with the vehicle’s brake
system. In addition, on longer downhill grades
the automatic transmission will downshift auto-
matically.

DISTRONIC Plus*
When activated, the DISTRONIC Plus adap-
tive cruise control system increases driv-
ing convenience afforded by the cruise
control during travel on expressways and
other major roadways.

If the DISTRONIC Plus distance sensor
detects a slower moving vehicle direct-
ly ahead, your vehicle speed will be re-
duced so that you follow that vehicle at
a preset distance.

If there is no vehicle directly ahead of
you, DISTRONIC Plus will function in
the same way as the cruise control
(
page 419).
DISTRONIC Plus functions within a speed
range of 0 to 120 mph.When travelling in Canada in a vehicle not
registered in Canada, you must switch off
the radar sensor system* (
page 282).
Canadian law does not permit the use of
the radar sensor system* (
page 282) for
vehicles from outside of Canada. When you
switch off the radar sensor system*, the
following functions are deactivated:

BAS Plus* (page 69)

vehicle ahead and your vehicle’s current
speed indicate that DISTRONIC Plus will not
be capable of slowing the vehicle sufficiently
to maintain the preset following distance,
which creates a danger of a collision.
Immediately brake your vehicle to increase
the distance between your vehicle and the
vehicle in front of you. The warning sound is
intended as a final caution that you have not
interceded with your own braking inputs to
avoid a potentially dangerous situation. Do
not wait for the operation of the warning sig-
nal to intercede with your own braking, as
that will result in potentially dangerous
emergency braking which will not always re-
sult in an impact being avoided.
Tailgating increases the risk of an accident.
Warning!G
DISTRONIC Plus brakes your vehicle with a
maximum of 13 ft/s2. This corresponds to
about 40% of the maximum deceleration
ability of your vehicle.
You must also apply the brakes yourself to
avoid a collision. DISTRONIC Plus brakes
the vehicle in an effort to restore the preset
distance or to maintain the speed. The brake
pedal is automatically applied as this hap-
pens which results in the brake pedal mov-
ing.
Keep driver’s foot area clear at all times, in-
cluding the area under the brake pedal. Ob-
jects stored in this area may impair pedal
movement which could interfere with the
braking ability of the DISTRONIC Plus sys-
tem.
Do not place your foot under the brake pedal
– your foot could become caught.Warning!G
If you do not receive visual or acoustic warn-
ing signals during a critical traffic situation,
DISTRONIC Plus has either not recognized
the collision risk, has been deactivated or is
malfunctioning.
Remember, whether or not DISTRONIC Plus
is operating, it is ultimately always the driv-
ers responsibility to apply the brakes in or-
der to control the vehicle and avoid a
collision.
iFor activating or deactivating the
DISTRONIC Plus system, see “Activating
DISTRONIC Plus” (

DISTRONIC Plus” (
