Roadside Assistance button 
Located below the center armrest cover is the Roadside 
Assistance button. Pressing and holding the 
button (for longer than 2 seconds) will initiate a call to a 
Mercedes-Benz Roadside Assistance dispatcher. The 
button will flash while the call is in progress. The 
message “ROADSIDE ASSISTANCE – CONNECTING 
CALL” will appear in the multifunction display. When 
the connection is established, the message “ROADSIDE 
ASSISTANCE – CALL CONNECTED” appears in the 
multifunction 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).
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 
multifunction 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:
•S ign  an d  Drive s erv ices : Ser vi ces  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 approx. 
10 seconds during the system self-check after turning 
electronic key in starter switch to position 2 (together 
with the “SOS” button and the Information 
button¡).
See system self-check on page 182 when the indicator 
lamp does not light up in red or stays on longer than 
approximately 10 seconds.

Technical
data Instruments 
and controlsOperationDrivingInstrument 
cluster displayPractical hints Car care Index Notes:
The malfunction indicator lamp¿ for the ESP is 
combined with that of the BAS.
The yellow BAS/ESP malfunction indicator lamp in the 
instrument cluster and the yellow ESP warning 
lampv in the speedometer dial come on with the 
electronic key in steering lock position 2. They should 
go out with the engine running.
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 ESP warning message is displayed, have the BAS 
or ESP checked at your authorized Mercedes-Benz 
Center as soon as possible.
For ESP warning message, see page 245.
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 lamp in speedometer 
dial c omes  on ). For  t his  r eason , all wheels , i nclud in g t he 
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.

Spare wheel
Spare wheel CLK 320 (except Sport Package)
Important!
The spare wheel rim is mounted with a full size tire of 
the same type as on the vehicle, and is fully functional. 
However, that spare wheel rim is weight optimized and 
has a limited service life of 12 000 miles (20 000 km) 
use before a standard wheel rim must replace it.
In the case of a flat tire, you may temporarily use the 
spare wheel.
Do not operate vehicle with more than one spare wheel 
mounted.
Unidirectional tires must always be mounted with arrow 
on tire sidewall pointing in direction of vehicle forward 
movement.
If the arrow on tire side wall does not point in direction 
of vehicle forward movement when using the spare 
wheel, observe the following restriction:
•Drive to the nearest tire repair facility as soon as 
possible.For rim and tire specifications, refer to “Technical Data” 
(page 314).
Spare wheel CLK 320 (with Sport Package), 
CLK 430, CLK 55 AMG
Important!
The spare wheel rim size is 7
1/2J x 17 H 2.
The spare wheel rim is mounted with a full size tire of 
the same type as on the vehicle’s front axle (CLK 320 
with Sport Package: the tire size is 205/55 R 16 91 H), 
and is fully functional. However, the spare wheel rim is 
weight optimized and has a limited service life of 
12 000 miles (20 000 km) use before a standard wheel 
rim must replace it.
Wa r n i n g !
The spare wheel rim is for temporary use only. Use 
for over a total of 12 000 miles (20 000 km) 
(aggregate of all uses) may cause wheel rim failure 
leading to an accident and possible injuries.

In the case of a rear axle flat tire (CLK 320 with Sport 
Package: In case of a flat tire), you may temporarily use 
the spare wheel, when observing the following 
restrictions:
•Do not exceed vehicle speed of 50 mph (80 km/h)
•Drive to the nearest tire repair facility to have the 
flat tire repaired or replaced as appropriate.

characteristics change when driving with a spare 
wheel mounted on the rear axle.The spare wheel should only be used temporarily, 
and replaced with a regular road wheel as quick as 
possible.
