The tire inflation pressure monitor is mal-
functioning.
A wheel without proper sensor was in-
stalled.

Have the tire inflation pressure moni-
tor checked by an authorized
Mercedes-Benz Center.

Change the wheel (

Tire pres.
Caution, tire defect!
The tire pressure has decreased signifi-
cantly in one or more tires.

Check and correct tire pressure as re-
quired (

Caution, tire defect
One or more tires is deflating.

Carefully bring the vehicle to a halt,
avoiding abrubt steering and braking
maneuvers.

Tire pres.
Check tires!
The tire pressure in one or more tires is
already below the minimum value.
The tire pressure in one or more tires is
low.

Carefully bring the vehicle to a halt,
avoiding abrubt steering and braking
maneuvers.

Change the wheel (
page 370).
Warning!
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. Contin-
ued driving with a flat tire will cause exces-
sive heat build-up and possibly a fire.

Warning!
G
Driving while these messages are displayed
can result in an accident. Have your brake
system checked immediately.
If there is a malfunction in the SBC brake
system, we recommend that the vehicle be
transported with all wheels off the ground
using flatbed or appropriate wheel lift / dolly
equipment.
A tow bar must be used if circumstances do
not permit the use of the recommended
towing methods and the vehicle requires
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on
the ground is only permissible for distances
u p t o 3 0 m i l e s ( 5 0 k m ) a n d a t a s p e e d n o t t o
exceed 30 mph (50 km / h). For more infor-
mation, refer to “Towing the vehicle”
(page 381).
If the SBC brake system enters its emergen-
cy operation mode, the driver must apply
significantly greater brake pedal pressure
and depress the pedal much further than
normal to obtain braking effect. If neces-
sary, apply full pressure to the brake pedal.
Brakes may only be applied to the front
wheels. Stopping distance is increased!
Low brake fluid in the reservoir may cause
the braking system to fail!
Don’t add brake fluid before checking the
brake system. Overfilling the brake fluid res-
ervoir can result in spilling brake fluid on hot
engine parts and the brake fluid catching
fire. You can be seriously burned.
iIf you find that the brake fluid in the
brake fluid reservoir has fallen to the
minimum mark or below, have the
brake system checked for brake pad
thickness and leaks.!Brake pad thickness must be visually
inspected by a qualified technician at
the intervals specified in the Service
Booklet.

360 Practical hintsReplacing bulbsRear lamps Notes on bulb replacement


Use only 12 volt bulbs of the same type
and with the specified watt rating.


Switch lights off before changing a bulb
to prevent short circuits.


Always use a clean lint-free cloth when
handling bulbs.


Your hands should be dry and free of oil
and grease.


If the newly installed bulb does not light
up, visit an authorized Mercedes-Benz
Center.


Have the LEDs and bulbs for the follow-
ing lamps replaced by an authorized
Mercedes-Benz Center:

Additional turn signal lamps in the
exterior rear view mirrors


High mounted brake lamp


Bi-Xenon* lamps


Front fog lamps

Warning!
G
Keep bulbs out of reach of children.
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
Halogen lamps contain pressurized gas. A
bulb can explode if you:

touch or move it when hot


drop the bulb


scratch the bulb
Wear eye and hand protection.
Because of high voltage in Bi-Xenon* lamps,
it is dangerous to replace the bulb or repair
the lamp and its components. We recom-
mend that you have such work done by a
qualified technician.

366 Practical hintsFlat tire
Flat tirePreparing the vehicle
Park the vehicle as far as possible from
moving traffic on a hard surface.

Turn on the hazard warning flashers.

Engage the steering wheel lock in the
straight-ahead position and set the
parking brake.

Move the selector lever toP.

Have any passenger exit the vehicle at
a safe distance from the roadway.
Sealing tires with TIREFIT (E 55 AMG) 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
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.

368 Practical hintsFlat tire
Unscrew the valve cap from tire
valve7.

Screw filler hosea onto tire valve7.

Insert electrical plug4 into vehicle
cigarette lighter socket.

Turn SmartKey in starter switch to
position1 (
page 31).
or

Press the KEYLESS-GO* start / stop
button (
page 33) on the selector le-
ver once. Do not depress brake pedal.

Press I on electric air pump switch8.
The electric air pump should now
switch on and inflate the tire.After five minutes, the pressure gauge
must display at least 26 psi (1.8 bar). The
air hose can become hot during inflation.
Please exercise appropriate caution.

If this tire pressure is not attained, turn
off the electric air pump, detach the fill-
er hose from the tire valve, and drive
vehicle back and forth very slowly ap-
proximately 30 ft (10 m).
This serves to better distribute the
TIREFIT sealant material inside the tire.

Unscrew the air pump’s air hose5
from flange6 of the TIREFIT contain-
er.

Screw air hose5 onto tire valve7.
Inflate the tire again.

After attaining a tire pressure of 26 psi
(1.8 bar), press 0 on electric air pump
switch8.
The electric air pump should now be
switched off.
iIf sealant has leaked out, let it dry. You
can then peel it off.
!Do not operate the electric air pump
longer than eight minutes without in-
terruption. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.
Warning!
G
If a tire pressure of 26 psi (1.8 bar) is not at-
tained, tire is too severely damaged for
TIREFIT to provide a reliable tire repair.
In this case, TIREFIT cannot properly seal
the tire.
Do not drive the vehicle.
Contact the nearest Mercedes-Benz Center
or call Roadside Assistance.

Flat tire

Turn SmartKey in starter switch to
position0 (
page 31).
or

Press the KEYLESS-GO* start / stop
button (
page 33) on the selector le-
ver twice. Do not depress brake pedal.

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.
If ti re pre ss ur e i s at l ea st 2 0 psi (1 .3 ba r ), 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 maximum duration of use:
300 miles (500 km) at 50 mph (80 km / h)
with the recommended tire pressure.
