instrument cluster or the multifunction
display is inoperative.
As a result, you will not be able to see
information about your driving conditions,
such as
R speed
R outside temperature
R warning/indicator lamps
R malfunction/warning messages
R failure of any systems
Driving characteristics may be impaired.
If you must continue to drive, do so with added
caution. Contact an authorized Mercedes-
Benz Center as soon as possible.
The language setting for the multifunction
display can be changed via COMAND
(Y page 81). Activating the instrument cluster

Steam from an overheated engine can cause
serious
burns
which can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until
the engine has cooled down.
During severe operating conditions, e.g. stop-
and-go traffic, the coolant temperature may
rise close to 248‡ (120†), i.e close to the
red zone of the temperature gauge.
! Excessive coolant temperature triggers a
warning in the multifunction display.
The engine should not be operated with a
coolant temperature above 248‡ (120†),
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 Limited
Warranty. Tachometer
The red marking on the tachometer
(Y page

29) denotes excessive engine speed.
! Avoid driving at excessive engine speeds,
as it may result in serious engine damage
that is not covered by the Mercedes-Benz
Limited Warranty.
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 instrument
cluster (Y page 29). G
Warning!
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose. Indicated temperatures just above the
freezing
point

do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges. Fuel gauge
The fuel gauge is on the left-hand side of the
instrument cluster

(Y page 29). Once the fuel
level has fallen below the reserve mark, the
yellow segment indicator for the fuel reserve
comes on. Driving systems

The DISTRONIC PLUS has not yet detected
the vehicle changing lanes. There will be
insufficient distance to the lane-changing
vehicle.
Narrow vehicles
Because of their narrow profile, the vehicles
traveling near the outer edges of the lane
have not yet been detected by the DISTRONIC
PLUS. There will be insufficient distance to
the preceding vehicles.
Obstacles and stationary vehicles
The DISTRONIC PLUS does not brake for
obstacles or stationary vehicles. If, for
example, the vehicle detected in front of you
changes lanes to bypass an obstacle or
stationary vehicle in front of it, the
DISTRONIC PLUS will not brake for the
obstacle or stationary vehicle. Cross-traffic
The DISTRONIC PLUS may inadvertently
detect crossing vehicles. If you switch on the
DISTRONIC PLUS, for example, at a traffic
light with cross traffic, the vehicle may
suddenly start to drive off.
Hill-start assist system
On uphill grades, the hill-start assist system
maintains the pressure in the brake system
for approximately 1 second after you have
released the brake pedal. Therefore, you can
start off smoothly without the vehicle moving
immediately after releasing the brake pedal. G
Warning!
The hill-start assist system is not designed to
function as a parking brake. It does not
prevent the vehicle from moving when parked
on an incline.
Always engage the electronic parking brake
in addition to shifting the automatic
transmission into park position P.
The hill-start assist system is inactive

than they actually are, for example:
R the bumper of a vehicle parked behind you
R a trailer hitch
R the back of a truck
In such cases, you should not use the
guidelines to judge the distance. You may
misjudge the distance which increases the
risk of impacting the objects.
Even when the object you approach is directly
on the ground do not approach the object any
closer than the red guideline. Red guideline
= indicates an approximate
distance of 10 in (0.25 m) from the rear of the
vehicle. Yellow guidelines ; indicate an
approximate distance of 3 ft (1 m) from the
rear of the vehicle. Blue guidelines :
indicate the approximate width required for
the vehicle.
