TIREFIT is a limited repair device. TIREFIT
cannot be used for cuts or punctures larger
than approximately 0.16 in (4 mm) and tire
damage caused by driving with extremely
low tire inflation pressure, or on a flat tire, or
a damaged wheel.
Do not drive the vehicle under such circum-
stances.
Contact your nearest Mercedes-Benz
Center for assistance or call Roadside
Assistance.
Warning!
G
Take care not to allow the contents of
T I R E F I T t o c o m e i n c o n t a c t w i t h h a i r , e y e s o r
clothing. TIREFIT is harmful if inhaled, swal-
lowed 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.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.

Mounting the spare wheel Preparing the vehicle
Prepare the vehicle as described
(
page 440).
Vehicles with Minispare wheel
(except E 55 AMG):
Take the Minispare wheel, wheel
wrench and the jack out of the cargo
compartment (
page 422).
Vehicles with collapsible tire (E 55 AMG
without folding third row seat only):
Take the collapsible tire, wheel wrench,
jack and electric air pump out of the
cargo compartment (
page 422).Lifting the vehicle
Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
or other sizable objects.
One wheel chock is included with the
vehicle tool kit (
page 419).
When changing wheel on a level surface:
Place the wheel chock in front of and
another sizable object behind the
wheel that is diagonally opposite to the
wheel being changed.
Always try lifting the vehicle using the jack
on a level surface. However, should
circumstances require you to do so on a
hill, place the wheel chock and the other
sizeable object as follows:
Place the wheel chock and another siz-
able object on the downhill side block-
ing both wheels of the axle not being
worked on.
Warning!
G
The dimensions of the spare wheel
(Minispare or collapsible tire) are different
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 accordingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire pressure and do not ex-
ceed a 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.
Do not switch off the ESP
® when a
Minispare wheel or spare wheel with
collapsible tire is mounted.

446 Practical hintsFlat tire
On wheel to be changed, loosen but do
not yet remove the wheel bolts (ap-
proximately one full turn with wrench). The jack take-up brackets are located di-
rectly behind the front wheel housings and
in front of the rear wheel housings.
1Jake take-up bracket
2Jack
Place jack2 on firm ground.
Position jack2 under take-up
bracket1 so that it is always vertical
(plumb-line) as seen from the side,
even if the vehicle is parked on an
incline.
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into either 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 not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) 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 ca-
pacity jackstands before working under the
vehicle.

447 Practical hints
Flat tire
Jack up the vehicle until the wheel is a
maximum of 1.2 in (3 cm) from the
ground. Never start engine while
vehicle is raised.Removing the wheel
1Alignment bolt
Unscrew upper-most wheel bolt and re-
move.
Replace this wheel bolt with alignment
bolt1 supplied in the tool kit.
Remove the remaining bolts.
Remove the wheel.
Mounting the spare wheel
Clean contact surfaces of wheel and
wheel hub.
Warning!
G
Position the jack only on the jack take-up
brackets designed for this purpose.
If the jack is not properly positioned, the ve-
hicle may slip off of the jack.
Warning!
G
The jack is intended only for lifting the
vehicle briefly for wheel changes. It is not
suited for performing maintenance work
under the vehicle.
Never start the engine when the vehicle
is raised.
Never lie down under the raised vehicle.
!Do not place wheel bolts in sand or dirt.
This could result in damage to the bolt
and wheel hub threads.!To avoid paint damage, place wheel flat
against hub and hold it there while in-
stalling first wheel bolt.

A driving convenience cruise control
system which helps the driver maintain
a pre-selected speed:
If there is no vehicle directly ahead,
the system operates in the same
way as conventional ->cruise con-
trol.

Distronic will reduce your vehicle
speed to the extent permitted by re-
duced throttle and up to 20% brak-
ing power to maintain the preset
