i Obey local speed limits. Use prudent
driving speeds appropriate to prevailing
conditions.
Raised level Only select the raised level if appropriate for
the driving situation encountered. Otherwise
the fuel consumption may increase and/or
the handling characteristics of the vehicle
may be unfavorable.

All-wheel drive (4MATIC)
In vehicles with all-wheel drive (4MATIC),
both axles are powered at all times when the
vehicle is being operated. The 4MATIC improves traction in conjunction with the
ESP
®
(Y page 65) and the Electronic Traction
System (4-ETS) (Y page 65). G
Warning!
If a drive wheel is spinning due to insufficient
traction:
R While driving off, apply as little throttle as
possible.
R While driving, ease up on the accelerator
pedal.
R Adapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The 4MATIC cannot prevent accidents
resulting from excessive speed.
! Do not tow with one axle raised. Doing so
could damage the transfer case, which is
not covered by the Mercedes-Benz Limited
Warranty. All wheels must be on or off the
ground. Observe instructions for towing the
vehicle with all wheels on the ground.
! Only conduct operational or performance
tests on a two-axle dynamometer. If such
tests are necessary, contact an authorized
Mercedes-Benz Center. You could
otherwise seriously damage the brake
system and/or the transfer case which is
not covered by the Mercedes-Benz Limited
Warranty.
i In winter operation, the maximum
effectiveness of the 4MATIC is only
achieved with winter tires ( Y page 251) or
snow chains as required. Parktronic system

parking aid with ultrasonic sensors designed
to assist the driver during parking maneuvers.

The Tele Aid system ( Telematic Alarm Identification on Demand)
The Tele Aid system consists of three types
of response:
R Automatic and manual emergency
R Roadside Assistance
R Information
The Tele Aid system is operational providing
that

the vehicle’s battery is charged, properly
connected, not damaged, and cellular and
GPS coverage is available. The Tele Aid
system utilizes the cellular network for
communication and the GPS ( Global
Positioning System) satellites for vehicle
location. If either of these signals are
unavailable, the Tele Aid system may not
function and if this occurs, assistance must
be summoned by other means.
i A Tele Aid call cannot be canceled. Even
if the Tele Aid system is not activated or
operational, the system will attempt to
connect the respective call. This may take
as

long as five minutes or more. As long as
the Tele Aid system attempts to connect a
call, you cannot operate the COMAND
system. Also, most functions in the control
system, such as the telephone function, are
suspended. Therefore, it is not advisable to
initiate any Tele Aid call unless the Tele Aid
system is activated and operational. To adjust the speaker volume during a Tele
Aid call do the following:
X
Press button W or X on the
multifunction steering wheel.
or
X Use the adjustment button on your
COMAND system.
System self-test The system performs a self-test after you
have switched on the ignition.

Warning!
A malfunction in the system has been
detected if any or all of the following
conditions occur:
R The indicator lamp in the SOS button does
not come on during the system self-test.
R The indicator lamp in Roadside Assistance
button º does not come on during the

R The indicator lamp in Information button
E does not come on during the system
self-test.
R The indicator lamp in the SOS button,
Roadside Assistance button º, or
Information button E remains
illuminated constantly in red after the
system self-test.
R The message Tele Aid Inoperative or
Tele Aid Not Activated appears in the
multifunction

display after the system self-
test
If a malfunction is indicated as outlined above,
the system may not operate as expected. In
case of an emergency, help will have to be
summoned by other means.
Have the system checked at the nearest
Mercedes-Benz Center or contact the
Response Center at 1-800-756-9018 (in the
USA) or 1-888-923-8367 (in Canada) as soon
as possible. 208

R
Break in new tires for approximately
60 miles (100 km) at moderate speeds.
R Regularly check the tires and rims for
damage.
Dented or bent rims can cause tire
inflation pressure loss and damage to the
tire beads.
R If the vehicle is heavily loaded, check tire
inflation pressure and correct as required.
R Do not allow your tires to wear down too
far. Adhesion properties on wet roads are
sharply reduced at tread depths of less
than 1
/ 8 in (3 mm).
R When replacing individual tires, you should
mount new tires on the front wheels first
(on vehicles with same-sized wheels all
around). Recommended tire inflation pressure
G
Warning!
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are
more likely to fail from being overheated.
Do

not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver’s door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading the tires can also result
in handling or steering problems, or brake
failure.
Your vehicle is equipped with the Tire and
Loading Information placard located on the
driver’s door B-pillar ( Y page 236). The tire inflation pressure should be checked
regularly. Only adjust the tire inflation
pressure on cold tires. The tires can be
considered cold if the vehicle has been
parked

for at least 3 hours or driven less than
1 mile (1.6 km). Depending on the ambient
temperature, the driving speed and the tire
load, the tire temperature changes. When the
tire temperature changes by 18‡ (10†), the
tire inflation pressure will change by
approximately 1.5 psi (0.1 bar). Keep this in
mind when checking tire inflation pressure on
warm tires and adjust the tire pressure only
if the tire inflation pressure is too low for the
current operating conditions. If you check the
tire inflation pressure when the tires are
warm, the reading will be higher than the cold
reading. This is normal. Do not let air out to
match the specified cold tire inflation
pressure. Otherwise, the tire will be
underinflated.
Follow recommended cold tire inflation
pressures listed on Tire and Loading
Information placard on the driver’s door
B-pillar.
Keeping the tires properly inflated provides
the best handling, tread life and riding
comfort.
In addition to the Tire and Loading
Information placard on the driver’s door
B-pillar, also consult the tire inflation
pressure label on the inside of the filler flap
for any additional information pertaining to
special driving situations. For more
information, see “Important notes on tire
inflation pressure” ( Y page 229).
i Data shown on Tire and Loading
Information placard example are for

specific to each vehicle and may vary from
data shown in the following illustration.
