Warning!
G
When leaving the vehicle, always remove the
SmartKey or the SmartKey with
KEYLESS-GO* from the starter switch, take
it with you, and lock the vehicle. Do not
leave children unattended in the vehicle, or
with access to an unlocked vehicle. Unsu-
pervised use of vehicle equipment may
cause an accident and/or serious personal
injury.

144 Controls in detailInstrument clusterTachometer
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 is displayed in
the instrument cluster (
page 24). For in-
formation on how to select the unit of the
displayed temperature, i.e. degrees Cel-
sius (°C) or degrees Fahrenheit (°F), see
“Selecting temperature display mode”
(
page 157).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. This
means that the accuracy of the displayed
temperature can only be verified by com-
parison 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.
!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.

Warning!
G
A driver’s attention to the road must always
be his/her primary focus when driving. For
your safety and the safety of others, we rec-
ommend that you pull over to a safe location
and stop before placing or taking a tele-
phone call. If you choose to use the tele-
phone while driving, please use the
hands-free device and only use the tele-
phone when weather, road and traffic condi-
tions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle.
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 14 m) every second.
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or
personal injury.

lower gear.Upshifting

Briefly press the gear selector lever to
the right in theD+direction
(page 176).
or

Press button2 on the right side of the
steering wheel (
page 181).
The transmission shifts to the next
higher gear.
If, instead of the manual program mode
symbol
M, thep symbol appears in
the multifunction display (
page 174),
shift to the next higher gear. The fuel
supply will otherwise be interrupted to
prevent the engine from overrevving.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.iWhen you brake or stop, the transmis-
sion shifts down to a gear from which
you can easily accelerate or take off.
!In the manual program modeM, the
transmission will not upshift, even if
the engine has reached its overrevving
range. Shift up to the next gear before
the engine has reached its overrevving
range. Make absolutely certain that the
engine speed does not reach the red
marking on the tachometer
(page 24). Otherwise the engine
could be damaged which is not covered
by the Mercedes-Benz Limited
Warranty.

248 Controls in detailDriving systemsVehicle level control
Your vehicle automatically adjusts its ride
height to

reduce fuel consumption


increase vehicle safety
The following vehicle chassis ride heights
can be selected:


Normal


RaisedThe vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed:


At a speed above approximately above
68 mph (110 km / h) and the sporty
suspension style selected
(page 247), ride height is reduced
automatically by up to approximately
0.6in (15mm).


With decreasing speed, the ride height
is again raised to the “Normal” level.Select the “Raised” level only when re-
quired by current driving conditions. Oth-
erwise


fuel consumption may increase


handling may be impaired
iThese height adjustments are so small
that you may not notice any change.
Warning!
G
To help avoid personal injury, keep hands
and feet away from wheel housing area, and
stay away from under the vehicle when low-
ering the vehicle chassis.

Driving instructions
Drive sensibly – save fuel
Fuel consumption, to a great extent, de-
pends on driving habits and operating con-
ditions.
To save fuel you should:

Keep tires at the recommended infla-
tion pressures.


Remove unnecessary loads.


Remove roof rack when not in use.


Allow engine to warm up under low
load use.


Avoid frequent acceleration and decel-
eration.


Have all maintenance work performed
at the intervals specified in the Mainte-
nance Booklet and as required by the
Maintenance System. Contact an au-
thorized Mercedes-Benz Center.
Fuel consumption is also increased by driv-
ing in cold weather, in stop-and-go traffic,
on short trips and in hilly area.
Drinking and driving
Pedals
Warning!
G
Drinking and driving and / or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgement.
The possibility of a serious or even fatal ac-
cident are greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Warning!
G
Keep driver’s foot area clear at all times. Ob-
jects stored in this area may impair pedal
movement.
