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 inflation pressures,
•remove unnecessary loads,
•remove roof rack when not in use,
•allow engine to warm up under low load use,
•avoid frequent acceleration and deceleration,
•have all maintenance work performed at regular
intervals by an authorized Mercedes-Benz Center.
Fuel consumption is also increased by driving in cold
weat her, i n stop -and -go traf f ic, on short trip s an d i n hilly
country.Drinking and driving
Ped al s
Wa r n i n g !
Drinking or taking drugs and driving can be a very
dangerous combination. Even a small amount of
alcohol or drugs can affect your reflexes,
perceptions and judgement.The possibility of a serious or even fatal accident is
sharply increased when you drink or take drugs
and drive.Please don’t drink or take drugs and drive or allow
anyone to drive after drinking or taking drugs.Wa r n i n g !
Keep driver’s foot area clear at all times. Objects
stored in this area may impair pedal movement.

Specified tire pressures must be maintained. This
applies particularly if the tires are subjected to high
loads (e.g. high speeds, heavy loads, high ambient
temperatures).
Aq uaplaning
Depending on the depth of the water layer on the road,
aquaplaning 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.
We recommend M+S rated radial-ply tires for the winter
season for all four wheels to insure normal balanced
handling characteristics. On packed snow, they can
reduce your stopping distance as compared with
summer tires. Stopping distance, however, is still
considerably greater than when the road is not snow or
ice covered.
Wa r n i n 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.
Wa r n i n 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.

fastened to a tightening torque of 80 ft.lb. (110 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 282.
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.

(C 32 AMG only)
Small punctures, particularly those in the tread can be
sealed with TIREFIT.
Foreign objects (e.g. screws or nails) should not be
removed from the tire.
TIREFIT can be used in ambient temperatures down to
approx. - 4
°F (- 20
°C).
Wa r n i n g !
Cuts or punctures larger than approx. 0.16 in
(4 mm), tire damage caused by driving with
extremely low tire pressure or on a flat tire, or a
damaged wheel can pose a hazard while driving.
TIREFIT should not be used in such circumstances.Do not drive the vehicle under such circumstances.Contact your nearest Mercedes-Benz Center for
assistance.Take care not to allow the contents of TIREFIT to
come in contact with hair, eyes or clothing.
TIREFIT is harmful if inhaled, swallowed or
absorbed through the skin - causes skin, eye and
respiratory irritation.
Any contact with eyes or skin should be flushed
immediately with plenty of water.If clothing comes in contact with TIREFIT, change
clothing as soon as possible.In case of allergic reaction or rash, consult a
physician immediately.Keep TIREFIT out of reach of children.
If swallowed, rinse mouth immediately with plenty
of water and drink plenty of water.Do not induce vomiting!Consult a physician immediately.Keep away from open flame or heat source.

11. Remove air pump from storage compartment inside
trunk.
12. Pull out air hose with pressure gauge (5) and
electrical plug (6).
13. Screw filler hose (5) onto tire valve.
14. Plug air pump electrical plug (6) into vehicle cigar
lighter.
15. To switch on air pump, turn key in steering lock to
position 1.
Note:
After 5 minutes, pressure gauge must display
26 psi (1.8 bar). Do not exceed the maximum pressure
of 36 psi (2.5 bar)!
If pressure is not attained, drive vehicle
approx. 394 in (10 m), so that the sealing material is
evenly distributed inside the tire. Reconnect air pump
and inflate tire.Note:
Do not operate electric air pump longer that 6 minutes
wit hout interruption. Air pump could overheat! Af ter air
pump has cooled off, operate air pump again.
16. To switch off air pump, turn key in steering lock to
position 0.
17. Reinstall valve tire cap.
18. Drive vehicle to distribute the sealant evenly inside
the tire.
Wa r n i n g !
If a tire pressure of 26 psi (1.8 bar) is not attained,
tire is too severely damaged for TIREFIT to provide
a reliable tire repair.In this case TIREFIT can not properly seal the tire.Do not drive the vehicle.Contact the nearest Mercedes-Benz Center or call
Roadside Assistance.

cluster displayPractical hintsCar care Index Notes:
If TIREFIT is liquid, clean water and a damp cloth will
remove the material from the vehicle or tire and wheel
components. Once TIREFIT sealing material had dried,
it can easily be peeled off and properly discarded.
Replace TIREFIT every 3 years.Tire inflation pressure
A table (see fuel filler flap) lists the tire inflation
pressures specified for Mercedes-Benz recommended
tires as well as for the varying operating conditions.
Important!
Tire pressure changes by approximately 1.5 psi (0.1 bar)
per 18
°F (10
°C) of air temperature change. Keep this in
mind when checking tire pressure inside a garage –
especially in the winter.
Example:
If garage temperature = approximately +68
°F (+20
°C)
and ambient temperature = approximately +32
°F (0
°C)
then the adjusted air pressure = specified air pressure
+3 psi (+0.2 bar).
Tire pressures listed for light loads are minimum values
offering high driving comfort. Increased inflation
pressures for heavy loads produce favorable handling
characteristics with lighter loads and are perfectly
permissible. The ride of the vehicle, however, will
become somewhat harder.
Tire temperature and pressure increase with the vehicle
speed. Tire pressure should therefore only be checked
and corrected on cold tires. Correct tire pressure in
Wa r n i n g !
Do not exceed vehicle speed of 50 mph (80 km / h).
A TIREFIT repair is not designed to operate at
higher speeds.Vehicle handling characteristics may change.After driving vehicle for an initial 10 minutes,
check tire pressure. If tire pressure has fallen
below 20 psi (1.3 bar) do not continue to drive the
vehicle.If tire pressure is at least 20 psi (1.3 bar), inflate
tire to correct pressure (see label on fuel filler
flap), and drive vehicle to nearest tire repair
facility to have tire repaired or replaced.Recommended duration of use: 300 miles (500 km)
at 50 mph (80 km / h) with the recommended tire
pressure.
