82 Safety and SecurityDriving safety systemsFour wheel electronic traction system (4MATIC) with the ESP
Models with all-wheel-drive only.
The 4MATIC improves vehicle’s ability to
use available traction, e.g. during winter
operation in mountains under snowy
conditions, by applying power to all four
wheels.Warning!
G
If you see the ESP warning lampv flash-
ing in the speedometer, proceed as follows:

While driving off, apply as little throttle
as possible


While driving, ease up on the accelera-
tor


Adapt your speed and driving style to
the prevailing road conditions
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP cannot prevent accidents resulting
from excessive speed.
!Do not tow with one axle raised.
Otherwise the transfer case can be
damaged, which is not covered by the
Mercedes-Benz Limited Warranty.!Performance testing must only be con-
ducted on a two-axle dynamometer.
Otherwise the transfer case can be
damaged, which is not covered by the
Mercedes-Benz Limited Warranty.
!Because of the ESP’s automatic
operation, the engine must be shut off
(SmartKey in starter switch position0
or1) when the parking brake is being
tested on a brake test dynamometer
Active braking action through ESP may
otherwise seriously damage the front
or rear axle brake system.
Operational tests with the engine
running can only be conducted on a
two-axle dynamometer.iAt highly demanding operating condi-
tions, the electronic traction system
may temporarily switch off to prevent
overheating of the drive wheel brakes.

normally.

110 Controls in detailLightingManual headlamp mode
The low beam headlamps and the parking
lamps can be switched on and off with the
exterior lamp switch.
Automatic headlamp mode
The following lamps switch on and off
automatically depending on the brightness
of the ambient light:

Low beam headlamps


Tail and parking lamps


License plate lamps


Side marker lamps

Turn the exterior lamp switch to
positionU.
With the SmartKey in starter switch
position1, only the parking lamps will
switch on and off automatically.
When the engine is running, the low
beam headlamps, the tail and parking
lamps, the license plate lamps, and the
side marker lamps will switch on and
off automatically.
iWith the SmartKey removed from the
starter switch and the driver’s door
open, a warning sounds if the parking
lamps or low beam headlamps are
switched on.
The message
Switch off lights.

appears in the multifunction display
Warning!
G
If the exterior lamp switch is set toU,

the headlamps may switch off unexpect-
edly when the system senses bright
ambient light, for example light from
oncoming traffic.


the headlamps will not be automatically
switched on under foggy conditions.
To minimize risk to you and to others,
activate headlamps by turning exterior lamp
switch toB when driving or when traffic
and / or ambient lighting conditions require
you to do so.
In low ambient lighting conditions, only
switch from positionU toB with the
vehicle at a standstill. Switching fromU
toB will briefly switch off the
headlamps. Doing so while driving in low
ambient lighting conditions may result in an
accident.
The automatic headlamp feature is only an
aid to the driver. The driver is responsible for
the operation of the vehicle's lights at all
times.

119 Controls in detail
Instrument cluster
Trip odometer
Make sure you are viewing the trip
odometer and main odometer in the
multifunction display (
page 121).

If it is not displayed, press buttonè
orÿ on the multifunction steering
wheel until the trip odometer appears
(page 122).

Press and hold the reset button in the
instrument cluster (
page 117) until
the trip odometer is reset.
Tachometer
The red marking on the tachometer
(page 24) denotes 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
!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.

120 Controls in detailInstrument clusterThe outside temperature is indicated in the
multifunction display (
page 121). For
information on how to select the unit of the
indicated temperature, i.e. degrees
Celsius (°C) or degrees Fahrenheit (°F),
see “Selecting temperature display mode”
(
page 135).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.
