Intermittent wiping
Only switch on intermittent wiping under
wet weather conditions or in the presence
of precipitation.
When you select intermittent wiping, the
rain sensor is activated. The rain sensor
automatically sets a suitable wiping
interval depending on the wetness of the
sensor surface.Turn the combination switch to
positionI.
After the initial wipe, pauses between
wipes are automatically controlled by
the rain sensor.Single wipe
Press the combination switch briefly in
direction of arrow1 to the resistance
point.
The windshield wipers wipe one time
without washer fluid.
Wiping with windshield washer fluid
Push the combination switch in direc-
tion of arrow1 past the resistance
point.
The windshield wipers operate with
washer fluid.
For information on filling up the washer
reservoir, see “Windshield/rear window
washer system and headlamp cleaning
system” (
page 275).
!Do not leave windshield wipers in intermit-
tent setting when the vehicle is taken to an auto-
matic car wash or during windshield cleaning.
Windshield wipers will operate in the presence of
water sprayed on the windshield, and windshield
wipers may be damaged as a result.
iIntermittent wiping is interrupted when the
vehicle is at a standstill and a front door is
opened. This protects persons getting into or out
of the vehicle from being sprayed.
Intermittent wiping will be continued when all
doors are closed and

the gear selector lever is in drive positionD
or reverse gearR
or

the wiper setting is changed using the
combination switchiTo prevent smears on the windshield, or
noisy/chattering wiper blades, wipe with wind-
shield washer fluid every now and then even
when it is raining.

132 Controls in detail
Instrument cluster
Tachometer
The red marking on the tachometer
(
page 26) 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
The outside temperature is displayed in
the multifunction display (
page 133).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 tem-
peratures rise. This prevents inaccurate
temperature 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 engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
Warning!G
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 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
The auto-dimming function does not react if
incoming light is not aimed directly at
sensors in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirrors do not react, for example,
when transporting cargo which covers the
rear window.
Light hitting the mirror(s) at certain angles
(incident light) could blind you. As a result,
you may not be able to observe traffic
conditions and could cause an accident.

200 Controls in detail
Driving systems
Rear Parking AssistThe Rear Parking Assist system is an
electronic aid designed to assist the driver
during parking maneuvers. It visually and
audibly indicates the relative distance
between the rear of the vehicle and an
obstacle.
The Rear Parking Assist system is
automatically activated when you

switch on the ignition
and

move the gear selector lever to reverse
gearR
Warning!G
Rear Parking Assist (rear Parktronic) is a
supplemental system. It is not intended to,
nor does it replace, the need for extreme
care. The responsibility during parking and
other critical maneuvers always remains
with the driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or road
curbs). Such objects may not be detected by
the system and can damage the vehicle.
The operational function of the Rear Parking
Assist can be affected by dirty sensors,
especially at times of snow and ice. See
“Cleaning the Rear Parking Assist sensors”
(
page 318).
Interference caused by other ultrasonic
signals (e.g. working jackhammers, car
wash, or the air brakes of trucks) can cause
the system to send erratic indications, and
should be taken into consideration.
Warning!G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.

201 Controls in detail
Driving systems
The Rear Parking Assist system monitors
the rear surrounding of your vehicle with
four sensors in the rear bumper.
1SensorsRange of the sensors
To function properly, the sensors must be
free of dirt, ice, snow, and slush. Clean the
sensors regularly, being careful not to
scratch or damage the sensors, see
“Cleaning the Rear Parking Assist sensors”
(
page 318).
!During parking maneuvers, pay special
attention to objects located above or below the
height of the sensors (e.g. planters or trailer
hitches). The Rear Parking Assist system will not
detect such objects at close range and damage
to your vehicle or the object may result.
Ultrasonic signals from outside sources (e.g.
working jackhammers, car wash, or the air
brakes of trucks) may impair the operation of the
Rear Parking Assist system.

Sensors
Minimum distance
If the system detects an obstacle in this
range, all the distance segments in the
warning indicator (
page 202) illuminate
and you hear a warning signal. If the
obstacle is closer than the minimum dis-
tance, the actual distance may no longer
be indicated by the system.Warning indicator
Visual signals indicate to the driver the
relative distance between the sensors and
an obstacle.
The warning indicator is located next to the
tailgate.
Warning indicator
1Distance segments
2Readiness indicatorThe warning indicator is divided into four
yellow, and two red distance segments1.
The Rear Parking Assist system is ready
when you hear a signal and the readiness
indicator2 is illuminated.
As your vehicle approaches an object, one
or more distance segments will illuminate,
depending on the distance. When the sixth
distance segment illuminates, you have
reached the minimum distance.
An intermittent acoustic warning will
sound when the fourth yellow distance
segment illuminates. This signal quickens
with each additional distance segment
illuminated. When all distance segments
illuminate, the acoustic warning becomes
a constant signal. The signal is canceled
when the gear selector lever is moved to
drive positionD or park positionP.

262 Operation
Driving instructions
Telephones and two-way radios
Radio transmitters, such as a portable
telephone or citizens band unit should only
be used inside the vehicle if they are
connected to an antenna that is installed
on the outside of the vehicle.
Refer to the radio transmitter operation
instructions regarding use of an external
antenna.Catalytic converter
Your Mercedes-Benz is equipped with
monolithic-type catalytic converters, an
important element in conjunction with the
oxygen sensors to achieve substantial
control of the pollutants in the exhaust
emissions. Keep your vehicle in proper
operating condition by following our
recommended maintenance instructions
as outlined in your Maintenance Booklet.
Warning!G
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,
possibly resulting in an accident and/or
personal injury.
!To prevent damage to the catalytic convert-
ers, use only premium unleaded gasoline in this
vehicle.
Any noticeable irregularities in engine operation
should be repaired promptly. Otherwise, exces-
sive unburned fuel may reach the catalytic
converter, causing it to overheat and potentially
start a fire.
Warning!G
As with any vehicle, do not idle, park or
operate this vehicle in areas where combus-
tible materials such as grass, hay or leaves
can come into contact with the hot exhaust
system, as these materials could be ignited
and cause a vehicle fire.

290 Operation
Tires and wheels
The TPMS only functions on wheels that
are equipped with the proper electronic
sensors. It monitors the tire inflation pres-
sure, as selected by the driver, in all four
tires. A warning is issued to alert you to a
decrease in pressure in one or more of the
tires.
Tire pressure inquiries are made using the
multifunction display.The present inflation
pressures are displayed only after a few
minutes travel time.Switch on the ignition (page 39).
Press buttonj ork until the
current inflation pressures for each tire
appear in the multifunction display.
Example illustration
iPossible differences between the readings
of a tire pressure gauge of an air hose, e.g. gas
station equipment, and the vehicle’s control
system can occur. Usually the readings issued by
the control system are more precise.
iWhen the vehicle has been parked for longer
than 20 minutes, the message
Tire pressure
displayed only after driving for a few
minutes
appears in the multifunction display.
Warning!G
It is the driver’s responsibility to calibrate
the TPMS on the recommended cold infla-
tion pressure. Underinflated tires affect the
ability to steer or brake the vehicle. You
might lose control over the vehicle.
iWith a spare wheel mounted, the system
may still indicate the tire inflation pressure of the
removed road wheel for some minutes. If this
happens, keep in mind that the indicated value
where the spare wheel is mounted does not
reflect the actual spare tire inflation pressure.

315 Operation
Vehicle care
You should check your vehicle from time to
time for stone chipping or other damage.
Any damage should be repaired as soon as
possible to prevent corrosion.
In doing so, do not neglect the underbody
of the vehicle. A prerequisite for a thor-
ough check is a washing of the underbody
followed by a thorough inspection. Dam-
aged areas need to be re-undercoated.
Your vehicle has been treated at the
factory with a wax-base rustproofing in the
body cavities which will last for the lifetime
of the vehicle. Post-production treatment
is neither necessary nor recommended by
Mercedes-Benz because of the possibility
of incompatibility between materials used
in the production process and others
applied later.We have selected car-care products and
compiled recommendations which are
specially matched to our vehicles and
which always reflect the latest technology.
You can obtain Mercedes-Benz approved
car-care products at an authorized
Mercedes-Benz Light Truck Center.
Scratches, corrosive deposits, corrosion or
damage due to negligent or incorrect care
cannot always be removed or repaired with
the car-care products recommended here.
In such cases it is best to seek aid at an
authorized Mercedes-Benz Light Truck
Center.
The following topics deal with the cleaning
and care of your vehicle and give important
“how-to” information as well as references
to Mercedes-Benz approved car-care
products.Power washer
Tar stains
Quickly remove tar stains before they dry
and become more difficult to remove. A tar
remover is recommended.
!Follow the instructions provided by the
power washer manufacturer on maintaining a
distance between the vehicle and the nozzle of
the power washer.
Never use a round nozzle to power-wash tires.
The intense jet of water can result in damage to
the tire.
Always replace a damaged tire.
Always keep the jet of water moving across the
surface. Do not aim directly at electrical parts,
electrical connectors, sensors, seals, or other
rubber parts.
