cluster displayPractical hints Car care Index 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
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. The nature of the need for assistance can
then be described. Sign and Drive services (jump start, a
few gallons of fuel or the replacement of a flat tire with
the vehicle spare tire) are available.
If the vehicle requires more than Sign and Drive
services, 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 other than Sign and Drive services, labor and / or
towing charges may apply. Refer to the Roadside
Assistance manual for more information.
Notes:
The indicator lamp in the Roadside Assistance
button remains illuminated in red for
approximately 5 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 220 when the indicator
lamp does not light up in red or stays on longer than
approximately 5 seconds.
Wa r n i n g !
If you feel at any way in jeopardy when in the
vehicle (e.g. smoke or fire in the vehicle, vehicle in
a dangerous road location), please do not wait for
voice contact after you have pressed the emergency
button. Carefully leave the vehicle and move to a
safe location. The Response Center will
automatically contact local emergency officials
with the vehicle’s approximate location if they
receive an “SOS” signal and cannot make voice
contact with the vehicle occupants.

It is advisable to set the parking brake whenever
parking or leaving the vehicle. In addition, move
selector lever to position “P” (manual transmission: first
or reverse gear). When parking on hills, always set the
parking brake.Tires
Tread wear indicators (TWI) are required by law. These
indicators are located in six places on the tread
circumference and become visible at a tread depth of
approximately
1/16 in (1.5 mm), at which point the tire is
considered worn and should be replaced.
The tread wear indicator appears as a solid band across
the tread.
Wa r n i n g !
If you feel a sudden significant vibration or ride
disturbance, or you suspect that possible damage to
your vehicle has occurred, you should turn on the
hazard warning flashers, carefully slow down, and
drive with caution to an area which is a safe
distance from the roadway.Inspect the tires and under the vehicle for possible
damage. If the vehicle or tires appear unsafe, have
it towed to the nearest Mercedes-Benz Center or
tire dealer for repairs.

Wheels
Replace rims or tires with the same designation,
manufacturer and type as shown on the original part.
See your authorized Mercedes-Benz Center for further
information.
See your authorized Mercedes-Benz 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. Rims
and tires must be of the correct size and type. For
dimensions, see “Technical Data”.
We recommend that you break in new tires for
approximately 60 miles (100 km) at moderate speed.

The jack is designed exclusively for jacking up the
vehi c le a t the j ack take-up b ra ckets b ui lt i nto eit her
side of the vehicle. To help avoid personal injury,
use the jack only to lift the vehicle during a wheel
change. Never get beneath the vehicle while it is
supported by the jack. Keep hands and feet away
from the area under the lifted vehicle. Always
firmly set parking brake and block wheels before
raising vehicle with jack.Do n ot d is engage parki n g brake w hil e t he vehi c le i s

when in use, especially on hills. Always try to use
the jack on level surface. Be sure that the jack arm
is fully seated in the jack take-up bracket. Always
lower the vehicle onto sufficient capacity
jackstands before working under the vehicle.

fastened to a tightening torque of 110 ft.lb. (150 Nm)
whenever wheels are mounted.
For rim and tire specifications, refer to “Technical Data”.Rotating wheels
The wheels can be rotated according to the degree of
tire wear while retaining the same direction of travel.
Rotating, however, should be carried out as
recommended by the tire manufacturer, before the
characteristic tire wear pattern (shoulder wear on front
wheels and tread center wear on rear wheels) becomes
visible, as otherwise the driving properties deteriorate.
Notes:
Thoroughly clean the inner side of the wheels any time
you rotate the wheels or wash the vehicle underside.
The use of retread tires is not recommended. Retread
tires may adversely affect the handling characteristics
and safety of the vehicle.
Dented or bent rims can cause tire pressure loss and
damage to the tire beads. For this reason, check rims for
damage at regular intervals. The rim flanges must be
checked for wear before a tire is mounted. Remove
burrs, if any.
Check and ensure proper tire inflation pressure after
rotating the wheels. For tire inflation pressure see
inside of fuel filler flap and also page 264.
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
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.Spare wheel
The spare wheel rim size is 7 J x 16 H2
(C 240 Canada only - steel rims 6
1/2 J x 16 H2).
In the case of a flat tire or breakdown, you may
temporarily use the 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 additional information, refer to page 352.
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.

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) may
cause wheel rim failure leading to an accident and
possible injuries. The dimensions of the spare wheel are different
from those of road wheels. As a result, the vehicle
handling characteristics change when driving with
a mounted spare wheel.The spare wheel should only be used temporarily,
and replaced with a regular road wheel as quickly
as possible.
