244 Controls in detailUseful features
Remote door unlock
In case you have locked your vehicle unin-
tentionally (e.g. SmartKey inside vehicle),
and the reserve SmartKey is not handy:
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 pass-
word which you provided when you
completed the subscriber agreement.

Then return to your vehicle and pull the
trunk recessed handle for a minimum
of 20 seconds until the SOS button is
flashing.
The message
Call connected
appears
in the multifunction display.
As an alternative, you may unlock the vehi-
cle via Internet using the ID and password
sent to you shortly after the completion of
your acquaintance call.
iThe indicator lamp in the respective
button flashes until the call is conclud-
ed. Calls can only be terminated by a
Response Center or Customer Assis-
tance Center representative except
Roadside Assistance and Information
calls, which can also be terminated by
pressing button ì on the multifunc-
tion steering wheel or the respective
button for ending a telephone call on
the COMAND headunit.
iWhen a Tele Aid call has been initiated,
the COMAND system audio is muted
and the selected mode (radio 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 sys-
tem (if engaged) will continue to run.
The display in the instrument cluster is
available for use and spoken com-
mands 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.

257 Operation
Driving instructions
To help prevent brake disk corrosion after
driving on wet road surfaces (particularly
salted roads), it is advisable to brake the
vehicle with considerable force prior to
parking. The heat generated serves to dry
the brakes.
If your brake system is normally only sub-
jected to moderate loads, you should occa-
sionally test the effectiveness of the
brakes by applying above-normal braking
pressure at higher speeds. This will also
enhance the grip of the brake pads.
If the parking brake is released and the
brake warning lamp in the instrument clus-
ter stays on, there is a malfunction in the
SBC brake system (
page 85) or 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 res-
ervoir.
Have the brake system inspected immedi-
ately.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
Mercedes-Benz Center.
Only install brake pads and brake fluid rec-
ommended by Mercedes-Benz.After hard braking, it is advisable to drive
on for some time, rather than immediately
parking, so the air stream will cool down
the brakes faster.
!Be very careful not to endanger other
road users when you apply the brakes.
Refer to the description of the Brake
Assist System (BAS) (
page 81).
Warning!
G
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substantially impaired. This
could result in an accident.
Be certain to read and observe the warning
notices on brake pad replacement
(page 86).
!When driving down long and steep
grades, relieve the load on the brakes
by shifting into a lower gear to use the
engine’s braking power. This helps pre-
vent overheating of the brakes and re-
duces brake pad wear.

392 Practical hintsFlat tire
After driving vehicle for an initial
10 minutes, check tire inflation pres-
sure using the pressure gauge on the
air pump.

Visit an authorized Mercedes-Benz
Center as soon as possible to obtain a
new TIREFIT kit.

Bring used TIREFIT materials to an au-
thorized Mercedes-Benz Center for
proper disposal.

Replace your TIREFIT container every
four years. Replacement containers are
available at your authorized
Mercedes-Benz Center.
Warning!
G
If tire inflation pressure has fallen below
20 psi (1.3 bar) do not continue to drive the
vehicle.
Park your vehicle safely away from the road-
way and contact the nearest authorized
Mercedes-Benz Center or Roadside
Assistance.
If tire inflation pressure is at least
20 psi (1.3 bar), inflate tire to correct pres-
sure (see placard on the driver’s door
B-pillar), and drive vehicle to nearest tire re-
pair facility to have tire repaired or replaced.
Recommended duration of use:
300 miles (500 km) at 50 mph (80 km/h)
with the recommended tire inflation pres-
sure.
Warning!
G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the pillar in the driver’s
door opening). Overloading the tires can
overheat them, possibly causing a blowout.
Warning!
G
Do not exceed vehicle speed of 50 mph
(80 km/h). A TIREFIT repair is not designed
to operate at higher speeds.
The sticker must be attached on the instru-
ment cluster where it will be easily seen by
the driver.
Vehicle handling characteristics may
change. Adapt your driving accordingly.

ing the control system.
Overspeed range
Engine speeds within the red marking
on the tachometer dial, see “Tachome-
ter” (
page 132). Avoid this engine
speed range, as it may result in serious

nents used to generate and transmit

tions and raised automatically. It may

ing situations.RON

line’s ability to resist undesired detona-
tion (knocking). The average of both

RON (Research Octane Number) is
posted at the pump, also known as
ANTI-KNOCK INDEX.
SBC
(S
ensotronic B
rake C
ontrol)

tion P without SmartKey turned and
