42 Getting startedDrivingDriving
Place the gear selector lever in
positionD orR.

Release the brake pedal.

Carefully depress the accelerator
pedal.
Once the vehicle is in motion, the automat-
ic central locking system engages and the
locking knobs drop down.After a cold start, the transmission engag-
es at a higher revolution. This allows the
catalytic converter to reach its operating
temperature earlier.iYou can open a locked door from the
inside. Open door only when conditions
are safe to do so.!If you hear a warning signal when driv-
ing off, you have forgotten to release
the parking brake.
Release the parking brake.
iWait for the gear selection process to
complete before setting the vehicle in
motion.Warning!
G
It is dangerous to shift the selector lever out
ofP orN if the engine speed is higher than
idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the en-
gine is idling normally and when your right
foot is firmly on the brake pedal.
!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.

108 Controls in detailInstrument cluster
Instrument clusterA full view illustration of the instrument
cluster can be found in the “At a glance”
section of this manual (
page 20).
The instrument cluster is activated when
you:


open a door


turn on the ignition


press the reset knob (
page 20)


switch on the exterior lamps
Only opening a door will activate the in-
strument cluster for approximately
30 seconds.
You can change the instrument cluster set-
tings in the Instrument cluster submenu of
the control system (
page 122).
Instrument cluster illumination
Use the reset knob to adjust the illumina-
tion brightness for the instrument cluster
and the switches on the center console.
To brighten illumination
Turn the reset knob in the instrument
cluster (
page 20) clockwise.
The instrument cluster illumination will
brighten.To dim illumination

Turn the reset knob in the instrument
cluster (
page 20) counterclockwise.
The instrument cluster illumination will
dim.
Coolant temperature gauge
Under normal driving conditions, the cool-
ant temperature may rise to 248°F
(120°C). The coolant temperature may
rise to 266°F (130°C) at high outside tem-
peratures or when driving in hilly terrain.
The engine should not be operated with
the coolant temperature above 266°F
(130°C). Doing so may cause serious en-
gine damage which is not covered by the
Mercedes-Benz Limited Warranty.
iThe instrument cluster illumination is
dimmed or brightened to suit ambient
light conditions.

Trip odometer
Make sure that you are viewing the trip
odometer display (
page 110).
Press the
j
or
k
button on the mul-
tifunction steering wheel repeatedly until
the trip odometer appears if it is not dis-
played.

Press and hold reset knob4
(page 20) until the trip odometer is
reset.
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.

denoting excessive engine speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated at
an excessive speed.
Outside temperature indicator
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.
!Avoid driving at excessive engine
speeds, as it may result in serious en-
gine 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.

110 Controls in detailControl system
Control systemThe control system is activated as soon as
the key in the starter switch is turned to
position1. The control system enables you
to

call up information about your vehicle


change vehicle settings
For example, you can use the control sys-
tem to find out when your vehicle is next
due for service, to set the language for
messages in the instrument cluster dis-
play, and much more.
The control system relays information to
the multifunction display.
Multifunction display
The multifunction display consists of the
display fields in the speedometer and the
tachometer. In its default state, the left
display field shows the trip and main
odometer, while the present outside tem-
perature appears in the right display field.
This default setting is referred to as the
standard display.

Warning!
G
A driver’s attention to the road and traffic
conditions must always be his /her primary
focus when driving.
For your safety and the safety of others, se-
lecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions per-
mit it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km / h), your vehicle is
covering a distance of 44 feet (approximate-
ly 13.5 m) every second.
