Storing exterior rear view mirror positions
(only vehicle with memory function)
The exterior rear view mirror positions are stored in
memory with the seat positions and can be recalled
when necessary. See page 43 for notes on the memory
function.
Parking position (only vehicle with memory function)
The passenger side exterior mirror can be adjusted and
programmed to assist the driver during parking
maneuvers (e.g. to observe the curb or other objects
close to the vehicle).
With the key in steering lock position 2, and the exterior
rear view mirror switch in the passenger side position,
the passenger side mirror will be turned downward
when placing the gear selector lever in “R” reverse.
The passenger side mirror will return to its previous
position:
•immediately at speeds above approx. 6 mph
(10 km/h) – independent of the engaged gear,
•after 10 seconds when shifting gear selector lever
from “R” Reverse,
•by pressing the driver’s side mirror button%.To store passenger side mirror parking position:
1. The vehicle must be stationary.
Turn key to steering lock position 1 or 2.
2. Select passenger side mirror& and adjust the
mirror to view the curb.
3. Push the memory button “M”, see page 43.
4. Within 3 seconds push bottom of adjustment
button (3), see page 77.
The mirror should not move.
Repeat the memory procedure if the mirror moves.
Note:
The selected position will be stored relative to the
memory button (1, 2, 3) pushed.

Te ch n i c a l

cluster displayPractical hints Car care Index Important!
If the indicator lamp continues to flash or the system
does not reset, contact the Response Center at
1-800-756-9018 (in the USA) or 1-888-923-8367 (in
Canada), or Mercedes-Benz Customer Assistance at
1-800-FOR-MERCedes (1-800-367-6372) in the USA or
Customer Service at 1-800-387-0100 in Canada.
Notes:
The indicator lamp for the respective button flashes
until the call is concluded and this can only be
completed by a Response Center or Customer
Assistance Center representative, except Roadside
assistance and Information calls, which can also be
terminated by using the End button on the MCS unit.
When a Tele Aid call has been initiated, the MCS system
audio is muted and the selected mode (radio, tape or
CD) pauses. The optional cellular phone (if installed)
switches off. If you must use this phone, the vehicle
must be parked. Disconnect the coiled cord and place
the call. The navigation system (if engaged) will
continue to run. A pop-up window will appear in the
MCS display to indicate that a Tele Aid call is in
progress.Remote door unlock
In the case you have your vehicle locked unintentionally
(e.g. key inside vehicle), and no other key is available,
contact the Mercedes-Benz Response Center at
1-800-756-9018 (in the USA) or 1-888-923-8367 (in
Canada). You will be asked to provide your password
which you provided when you completed the subscriber
agreement.
Then return to your vehicle and pull outside handle of
liftgate for a minimum of 20 seconds until the “SOS”
button is flashing.
As an alternative, you may unlock the vehicle via
Internet using the ID and password sent to you shortly
after the completion of your Acquaintance Call.
The Response Center will then unlock your vehicle with
the remote door unlocking feature.
Note:
The remote door unlock feature is available if the
relevant cellular phone network is available.
The SOS button will flash and the message
“EMERGENCY CALL – CALL CONNECTED” will appear
in the MCS display to indicate receipt of the door unlock
command.

BrakesExcessive use of road salt and other snow melting
chemicals spread on roads during the winter months
may cause a build up of moisture or residue to form on
the braking components. This build up or residue could
cause light corrosion of the braking components if the
vehicle is parked with the brakes cold. Apply steady and
even braking pressure when stopping the vehicle to
warm up and dry the brake components.
Important!
Please pay attention to the function of the brake assist
system (BAS), see page 217.
The condition of the parking brake system is checked
each time the vehicle is in the shop for the required
maintenance service.
If the parking brake is released and the brake warning
lamp in the instrument cluster stays on and there is no
audible warning (EBP), the brake fluid level in the
reservoir is too low.
Brake pad wear or a leak in the system may be the
reason for low brake fluid in the reservoir.
Have the brake system inspected at an authorized
Mercedes-Benz Light Truck Center immediately.
Wa r n i n g !
When the engine is not running, the brake and
steering systems are without power assistance.
Under these circumstances, a much greater effort is
necessary to stop or steer the vehicle.Wa r n i n g !
After driving in heavy rain for some time without
applying the brakes or through water deep enough
to wet brake components or salty road conditions,
the first braking action may be somewhat reduced
and increased pedal pressure may be necessary to
obtain expected braking effect. Be sure to maintain
a safe distance from vehicles in front.Resting your foot on the brake pedal will cause
excessive and premature wear of the brake pads.It can also result in the brakes overheating thereby
significantly reducing their effectiveness. It may
not be possible to stop the vehicle in sufficient time
to avoid an accident.

Te ch n i c a l

If the BAS / ESP malfunction indicator lamp¿ comes
on continuously with the engine running, a malfunction
has been detected in either system. Only partial engine
output will be available.
If the BAS malfunctions, the brake system functions in
the usual manner, but without BAS.
If the BAS / ESP malfunction indicator lamp stays
illuminated, have the BAS or ESP checked at your
authorized Mercedes-Benz Light Truck Center as soon
as possible.
With the ABS malfunctioning, the ESP is also switched
off.
Driving the vehicle with varied size tires will cause the
wheels to rotate at different speeds, therefore the ESP
may activate (yellow ESP warning lampv in
speedometer dial comes on). For this reason, all wheels,
including the spare wheel, must have the same tire
outside diameter.
When testing the parking brake on a brake test
dynamometer, the engine must be shut off. Otherwise,
the ESP will immediately be engaged and will apply the
rear wheel brakes.In winter operation, the maximum effectiveness of the
ESP is only achieved with Mercedes-Benz recommended
M+S rated radial-ply tires and / or snow chains.
Synchronizing ESP
If the power supply was interrupted (battery
disconnected or empty), the BAS / ESP malfunction
indicator lamp may be illuminated with the engine
running.
Turn steering wheel completely to the left and then to
the right. The BAS / ESP malfunction indicator lamp
should go out.
If battery voltage drops below 10 volts, the indicator
lamp comes on and the brake assist system (BAS) is
deactivated. If the battery voltage rises and exceeds
10 volts, the BAS / ESP malfunction indicator lamp goes
out, and brake assist system (BAS) is functional again.
After driving off the BAS / ESP malfunction indicator
lamp should go out after approximately 110 - 220 yd
(100 - 200 m).

Parking assist (Parktronic)
(optional)
The Parktronic system assists the driver during parking
maneuvers. It visually and audibly indicates the
distance between the vehicle and an obstacle.
The front area of the vehicle is monitored when driving
forward. When reversing, the rear areas are monitored.
With the electronic key in steering lock position 2,
Parktronic engages automatically at speeds up to
approximately 10 mph (15 km / h) and deactivates
during higher speeds.
Parktronic can be switched off by a control switch
located in the center console. It engages automatically
again when starting the engine.
See page 234 for parktronic switch.
Wa r n i n g !
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 rests always with the driver.Special attention must be paid to objects having
smooth surfaces or low silhouettes (e.g. trailer
couplings, painted posts, or street curbs). Such
objects may not be detected by the system and can
damage the vehicle.The operational function of the Parktronic can be
affected by dirty sensors, especially at times of
snow and ice. See page 301 for notes on cleaning
the parktronic system sensors.Interference caused by other ultrasonic signals
(e.g. working jackhammers or the air brakes of
trucks) can cause the system to send erratic
indications, and should be taken into
consideration.
