153 Tele Aid
Te ch n ica l
data Instruments 
and controlsOperationDrivingInstrument 
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 f lat 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 148 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.
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 288.
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 torq ue of 110 ft.lb. (150 Nm) 
whenever wheels are mounted.
For rim and tire specifications, refer to technical data on 
page 288.
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 f lat 
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 288.

To realize the total crumple zone in case of a rear end 
collision, the space-saver spare wheel must be stored in 
its holder with the tire deflated. Properly inflate the tire 
prior to mounting it on the axle. See page 249 for 
detailed instructions.
When storing the space-saver spare wheel in its holder, 
tighten the three wheel bolts with a tightening torque of 
37 ft.lb. (50 Nm).Space-saver tire (except ML 55 AMG)
