Open the storage compartment be-
tween the backrests (
page 210).

Press and hold the button1 for longer
than 2 seconds.
A call to a Mercedes-Benz Roadside
Assistance dispatcher will be initiated.
The button• will flash while the call
is in progress. The message Connecting Call
will appear in the
multifunction display.When the connection is established, the
message
Call Connected
appears in the
multifunction display. The Tele Aid system
will transmit data generating the vehicle
identification number, model, color and lo-
cation (subject to availability of cellular
and GPS signals).
A voice connection between the Roadside
Assistance dispatcher and the occupants
of the vehicle will be established.

Describe the nature of the need for
assistance.
The Mercedes-Benz Roadside Assistance
dispatcher will either dispatch a qualified
Mercedes-Benz technician or arrange to
tow your vehicle to the nearest authorized
Mercedes-Benz Center. For services such
as labor and/or towing, charges may
apply. Refer to the Roadside Assistance
Manual for more information.These programs are only available in the
USA:


Sign and Drive services: Services such
as jump start, a few gallons of fuel or
the replacement of a flat tire are
obtainable.
i
If the indicator lamp in the Roadside Assis-
tance button• is flashing continuously and
there was no voice connection to the Response
Center established, then the Tele Aid system
could not initiate a Roadside Assistance call (e.g.
the relevant cellular phone network is not avail-
able). The message
Call Failed!
appears in
the multifunction display.
Roadside Assistance calls can be terminated us-
ing the tbutton on the multifunction
steering wheel.

235 Operation
Driving instructions
Driving instructions
Drive sensibly – save fuel
Fuel consumption, to a great extent,
depends on driving habits and operating
conditions.
To save fuel you should:

Keep tires at the recommended tire
inflation pressures.


Remove unnecessary loads.


Allow engine to warm up under low
load use.


Avoid frequent acceleration and
deceleration.


Have all maintenance work performed
at the intervals specified in the
Maintenance Booklet and as required
by the maintenance service display.
Contact an authorized Mercedes-Benz
Center.
Fuel consumption is also increased by
driving in cold weather, in stop-and-go
traffic, on short trips and in hilly area.
Drinking and driving
Pedals
Warning!
G
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgment.
The possibility of a serious or even fatal
accident are greatly increased when you
drink or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Warning!
G
Make sure that absolutely no objects are ob-
structing the pedals’ range of movement.
Keep the driver’s footwell clear of all obsta-
cles. If there are any floormats or carpets in
the footwell, make sure that the pedals still
have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents
and/or injury.

241 Operation
Driving instructions
The treadwear indicator appears as a solid
band across the tread.Specified tire inflation pressures must be
maintained. This applies particularly if the
tires are subjected to high loads (e.g. high
speeds, heavy loads, high ambient
temperatures).
For more information, see “Tires and
wheels” (
page 259).
Hydroplaning
Depending on the depth of the water layer
on the road, hydroplaning may occur, even
at low speeds and with new tires. Reduce
vehicle speed, avoid track grooves in the
road and apply brakes cautiously in the
rain.Tire traction
The safe speed on a wet, snow covered or
icy road is always lower than on a dry road.
You should pay particular attention to the
condition of the road whenever the outside
temperatures are close to the freezing
point.
Warning!
G
Although the applicable federal motor
vehicle safety laws consider a tire to be
worn when the treadwear indicators (TWI)
become visible at approximately
1/16in
(1.6 mm), we recommend that you do not
allow your tires to wear down to that level.
As tread depth approaches
1/8in (3 mm),
the adhesion properties on a wet road are
sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.
Have worn tires replaced in pairs (front pair
or rear pair). Otherwise the driving stability
of the vehicle will be adversely affected.
Warning!
G
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle. You
may lose control of the vehicle. Continued
driving with a flat tire or driving at high
speed with a flat tire will cause excessive
heat build-up and possibly a fire.!
A wheel change should only be carried out
at an authorized Mercedes-Benz Center. Other-
wise there is a danger of damaging the vehicle by
jacking it up incorrectly.
Warning!
G
If ice has formed on the road, tire traction
will be substantially reduced. Under such
weather conditions, drive, steer and brake
with extreme caution.

249 Operation
At the gas station
Coolant
For normal replenishing, use water (pota-
ble water quality). For more information,
see “Coolant” (
page 255) and see “Fu-
els, coolants, lubricants, etc.”
(
page 393).
Engine oil level
For more information on engine oil level,
see “Engine oil” (
page 253).
Brake fluidWindshield washer and headlamp
cleaning system
For more information on filling up the
washer reservoir, see “Windshield washer
system and headlamp cleaning system”
(
page 257).
Vehicle lighting
Check function and cleanliness. For more
information on replacing light bulbs, see
“Replacing bulbs” (
page 361).
For more information on exterior lamps,
see “Exterior lamp switch” (
page 106).Tire inflation pressure
For more information on tire inflation pres-
sure, see “Checking tire inflation pressure
manually” (
page 271).
!
If you find that the brake fluid in the brake
fluid reservoir has fallen to the minimum mark or
below, have the brake system checked for brake
pad thickness and leaks immediately. Notify an
authorized Mercedes-Benz Center immediately.
Do not add brake fluid as this will not solve the
problem. For more information, see “Practical
hints” (page 307).
