234 Practical hintsFlat tire
Visit an authorized Mercedes-Benz 
Center as soon as possible to obtain a 
new TIREFIT kit.
Bring used TIREFIT materials to an 
authorized Mercedes-Benz Center for 
proper disposal.
Replace your TIREFIT container every 
four years. Containers are available at 
your authorized Mercedes-Benz Cen-
ter.
Sealing tires with TIREFIT kit 2
Small tire punctures, only those in the 
tread, can be sealed with TIREFIT.
TIREFIT can be used in ambient tempera-
tures down to -4°F (-20°C).
Warning!
G
Follow recommend tire pressures.
Do not overinflate tires. Overinflating tires 
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes 
etc.
Do not underinflate tires. Underinflated tires 
wear unevenly, adversely affect handling 
and fuel economy, and are more likely to fail 
from being overheated.
Do not overload the tires by exceeding the 
specified vehicle capacity weight (as indicat-
ed by the label on the driver’s door latch 
post). Overloading the tires can overheat 
them, possibly causing a blowout.
Warning!
G
Keep TIREFIT away from sparks, open flame 
or heat source.
Do not smoke.
Warning!
G
Take care not to allow the contents of 
TIREFIT to come in contact with hair, eyes or 
clothing. TIREFIT is harmful if inhaled, swal-
lowed or absorbed through the skin. It caus-
es 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.Warning!
G
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.

Detach the electric air pump.
The air hose may still be hot. Please ex-
ercise appropriate caution.
Store the electrical plug and the air 
hose behind the flap and place the air 
pump back in the trunk.
Close the trunk lid.
Drive away immediately.
The TIREFIT sealant will distribute itself 
evenly inside the tire.
After driving vehicle for an initial 
10 minutes, check tire pressure using 
the pressure gauge on the air pump.
Warning!
G
Do not exceed vehicle speed of 
50 mph (80 km / h). A TIREFIT repair is not 
designed to operate at higher speeds.
The sticker must be attached on the instru-
ment cluster where it will be easily seen by 
the driver.
Vehicle handling characteristics may 
change. Adapt your driving accordingly.
Warning!
G
If tire pressure has fallen below 
20 psi (1.3 bar) do not continue to drive the 
vehicle.
Park your vehicle safely away from the road-
way and contact the nearest authorized 
Mercedes-Benz Center or Roadside Assis-
tance. 
I f ti re  pre s su re  is  a t l ea s t 2 0 ps i (1 .3 bar ),  in -
flate tire to correct pressure (see label on 
fuel filler flap), and drive vehicle to nearest 
tire repair facility to have tire repaired or re-
placed.
Recommended duration of use: 
300 miles (500 km) at 50 mph (80 km / h) 
with the recommended tire pressure.

door opening). Overloading the tires can 
overheat them, possibly causing a blowout.

Mounting the spare wheel
More information on spare wheels with 
collapsible tires can be found in the “Tech-
nical data” section (
page 265).Preparing the vehicle
Prepare the vehicle as described under 
“Preparing the vehicle” on page 
(
page 229).
Turn pump holder counterclockwise to 
loosen (
page 207).
Take the spare wheel out of wheel well.
Lifting the vehicle
Prevent the vehicle from rolling away 
by blocking wheels with wheel chocks 
(not included) or other sizable objects.
When changing wheel on a level surface:
Place one chock in front of and one be-
hind the wheel that is diagonally oppo-
site to the wheel being changed.
When changing wheel on a hill:
Place chocks on the downhill side 
blocking both wheels of the other axle.
Take the vehicle tool kit and the jack 
out of the trunk.
Warning!
G
Do not exceed vehicle speed of 50 mph 
(80 km/h). A TIREFIT repair is not designed 
to operate at higher speeds.
The sticker must be attached on the instru-
ment cluster where it will be easily seen by 
the driver.
Vehicle handling characteristics may 
change. Adapt your driving accordingly.
Warning!
G
The dimensions of the spare wheel are dif-
ferent from those of the road wheels. As a 
result, the vehicle handling characteristics 
change when driving with a spare wheel 
mounted. Adapt your driving style accord-
ingly.
The spare wheel is for temporary use only. 
When driving with spare wheel mounted, en-
sure proper tire pressure and do not exceed 
vehicle speed of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Center 
as soon as possible to have the spare wheel 
replaced with a regular road wheel.
Never operate the vehicle with more than 
one spare wheel mounted.

Detach the electric air pump.
Reinstall tire valve cap.
Stow the electrical plug and the air 
hose behind the flap and place the air 
pump back in the trunk.
Close the trunk lid.Storing collapsible spare wheel in 
wheel well
Before you can store the spare wheel with 
collapsible tire in the wheel well you have 
to release the air pressure of the tire.
Unscrew valve stem removal tool, 
which is part of the valve cap, from tire 
valve.
Using the valve stem removal tool, 
open tire valve slightly by turning the 
tire valve insert counterclockwise to 
release air pressure.
When the air pressure has been re-
leased, remove tire valve insert (pro-
tect it from dirt and sand) using the 
previously removed tire valve cap.
Once all air is out of the tire, and the 
tire has collapsed to its original shape, 
reinstall the tire valve insert and valve 
cap.
Place spare wheel in wheel well and 
secure it with the pump holder.

Rims and Tires
Rims and Tires
Use only tires and rims which have been 
specifically developed for your vehicle and 
tested and approved by Mercedes-Benz. 
Other tires and rims can have detrimental 
effects, such as
poor handling characteristics
increased noise
increased fuel consumption
!Moreover, tires and rims not approved 
by Mercedes-Benz may, under load, ex-
hibit dimensional variations and differ-
ent tire deformation characteristics 
that could cause them to come into 
contact with the vehicle body or axle 
parts. Damage to the tires or the vehi-
cle may be the result.
iFurther information on tires and rims is 
available at any authorized 
Mercedes-Benz Center. A tire inflation 
pressure table is located on the fuel fill-
er cap of the vehicle. The tire pressure 
should be checked regularly and 
should only be adjusted on cold tires. 
Follow tire manufacturer’s mainte-
nance recommendation included with 
vehicle.
