cluster displayPractical hints Car care Index When the connection is established, the message
“ROADSIDE ASSISTANCE – CALL CONNECTED”
appears in the MCS display. The Tele Aid system will
transmit data generating the vehicle identification
number, model, color and location (subject to
availability of cellular and GPS signals).
While the call is connected, you can change to
navigation menu by pressing NAVI button on the MCS.
A voice connection between the Roadside Assistance
dispatcher and the occupants of the vehicle will be
established. When a voice connection is established the
audio system mutes and the message “TELE AID –
ROADSIDE ASSISTANCE CALL ACTIVE” appears in the
MCS display. The nature of the need for assistance can
then be described. The Mercedes-Benz Roadside
assistance dispatcher will either dispatch a qualified
Mercedes-Benz technician or arrange to tow your
vehicle to the nearest 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
with the vehicle spare tire are obtainable,
•Remote Vehicle Diagnostics: This function permits
the Mercedes-Benz Roadside Assistance dispatcher
to download malfunction codes and actual vehicle
data.
Notes:
The indicator lamp in the Roadside Assistance
button• remains illuminated in red for
approximately 10 seconds during the system self-check
after turning key in steering lock to position 2 (together
with the “SOS” button and the Information
button¡).
See system self-check on page 166 when the indicator
lamp does not light up in red or stay on longer than
approximately 10 seconds.

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).

Wheels
Replace rims or tires with the same designation,
manufacturer and type as shown on the original part.
See your authorized Mercedes-Benz Light Truck Center
for further information.
See your authorized Mercedes-Benz Light Truck Center
for information on tested and recommended rims and
tires for summer and winter operation. They can also
offer advice concerning tire service and purchase.Tire replacement
Front and rear tires should be replaced in sets.
Furthermore – in the event of tire replacement – the
optional regular size spare wheel should be used on the
rear axle. Rims and tires must be of the correct size and
type. For dimensions, see technical data on page 310.
We recommend that you break in new tires for
approximately 60 miles (100 km) at moderate speed.
It is imperative that the wheel mounting bolts be
fastened to a tightening torque of 110 ft.lb. (150 Nm)
whenever wheels are mounted.
For rim and tire specifications, refer to technical data on
page 310.
Wa r n i n g !
Do not mix different tire construction types (i.e.
radial, bias, bias-belted) on your vehicle because
handling may be adversely affected and may result
in loss of control.
Wa r n i n g !
Worn, old tires can cause accidents. If the tire tread
is badly worn, or if the tires have sustained
damage, replace them.When replacing rims, use only genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can result in
the bolts loosening and possibly an accident.

Spare wheel
In the case of a flat tire or break-down, you may
temporarily use the space-saver spare wheel, while
observing the following restrictions:
•Do not exceed vehicle speed of 50 mph (80 km / h).
•Drive to the nearest repair facility to have the flat
tire repaired or replaced as appropriate.
•Do not operate vehicle with more than one spare
wheel mounted.
For rim and tire specifications, refer to “Technical data”
on page 310.
Caution!
Exercise care when removing or installing spare wheel
to prevent personal injury.Space-saver tire (ML 55 AMG only)
Removing spare wheel (space-saver tire):
1. Open buckle of clamp, then remove cover (1).
2. Unscrew the three wheel bolts using wrench
supplied with vehicle tools, and take out space-saver
spare wheel, and remove the air pump from its
compartment.
Wa r n i n g !
The dimensions of the spare wheel are different
from those of the road wheels. As a result, the
vehicle handling characteristics change when
driving with a mounted spare wheel.
