cluster displayPractical hints Car care Index Parking position
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 electronic 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 mirror position can now be adjusted as desired.
The passenger side mirror will return to its previous
position:
•immediately at speeds above approximately 6 mph
(10 km / h) - independent of the engaged gear,
•after 20 seconds when shifting gear selector lever
from “R” Reverse,
•by pressing the driver’s side mirror button %.One passenger-side mirror position can be stored in
memory. To do so:
1. Turn electronic key to steering lock position 2.
The vehicle must be stationary.
2. Select passenger-side mirror and adjust the mirror
to view the curb.
3. Press green memory button located in switch cluster
for driver seat, see page 45.
4. Within 2 seconds pull the mirror toggle switch
rearward. The mirror should not move.
Repeat the memory procedure if the mirror moves.

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 in the respective button flashes until
the call is concluded. Calls can only be terminated by a
Response Center or Customer Assistance Center
representative except Roadside Assistance and
Information calls, which can also be terminated by
pressing ìbutton on the multifunction steering
wheel.When a Tele Aid call has been initiated, the audio
system or the COMAND system audio (only vehicles
with COMAND) 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 COMAND navigation system (if
engaged) will continue to run. The display in the
instrument cluster is available for use and spoken
commands are only available by pressing the RPT
button on the COMAND unit. A pop-up window will
appear in the COMAND display to indicate that a Tele
Aid call is in progress.

Power assistance
BrakesExcessive use of 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 225.
If the parking brake is released and the brake warning
lamp in the instrument cluster stays on, 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 Center immediately.
All checks and service work on the brake system should
be carried out by an authorized Mercedes-Benz Center.
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.

Parking assist (Parktronic)
(optional)
The Parktronic system assists the driver during parking
maneuvers. It visually and audibly indicates the relative
distance between the vehicle and an obstacle.
The front area of the vehicle is monitored when driving
forward. When reversing, the front as well as 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 238 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 317 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.
