172 Controls in detailDriving systemsWarning!
G
Distronic cannot take street and traffic con-
ditions into account. Only use Distronic if
the weather and traffic conditions make it
advisable to travel at a steady speed.Warning!
G
Use of Distronic can be dangerous on slip-
pery roads. Rapid changes in tire traction
can result in wheel spin and loss of control.
Distronic does not act upon adverse sight
distance conditions. Do not use Distronic
during conditions of fog and heavy rain,
snow or sleet.
Warning!
G
Close attention to road and traffic condi-
tions is imperative at all times, regardless of
whether or not Distronic is activated.
Use of Distronic can be dangerous on wind-
ing roads or in heavy traffic because condi-
tions do not allow safe driving at a steady
speed.
Distronic will not react to stationary objects
in the roadway (e.g. a stopped vehicle in a
traffic jam or a disabled vehicle). Distronic
will also not respond to oncoming vehicles.
Switch off Distronic:

when changing from the left to the right
lane if vehicles are moving more slowly
in the left lane


when entering a turn lane or highway off
ramp


in complex driving situations, such as in
highway construction zones
In these situations, Distronic will continue to
maintain the set speed unless deactivated.
Distronic is designed and intended only to
maintain a set speed and keep a set dis-
tance from moving objects in front of it.Warning!
G
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

236 OperationTires and wheelsRegularly check your tire pressure at inter-
vals of no more than 14 days.
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 where the
temperature is different from the outside
temperature.
The tire temperature and with it the tire
pressure is increased also while driving,
depending on the driving speed and the
tire load.
Checking tire pressure electronically*
The tire inflation pressure monitor only
functions on wheels that are equipped with
the proper electronic sensors. It monitors
the tire inflation pressure, as selected by
the driver, in all four tires. A warning is is-
sued to alert you to a decrease in pressure
in one or more of the tires.Tire pressure inquiries are made using the
multifunction display (
page 110). The
present inflation pressures are displayed
only after a few minutes travel time.
You can select the unit of measure used for
the tire inflation pressure by changing the
setting in the control system (
page 129).

Switch on ignition.

Press
k
button until the current in-
flation pressures for each tire appear in
the tachometer display field.
iPossible differences between the read-
ings of a tire pressure gauge of an air
hose, e.g. gas station equipment, and
the vehicle’s control system can occur.
The readings issued by the control sys-
tem are more precise.
Warning!
G
The tire inflation pressure monitor does not
indicate a warning for wrongly selected in-
flation pressures. Always adjust tire inflation
pressure according to the label on the fuel
filler flap.
The tire inflation pressure monitor is not
able to issue a warning due to a sudden loss
of pressure (e.g. tire puncture caused by a
foreign object). In the event of a sudden loss
of pressure, bring the vehicle to a halt by
carefully applying the brakes and avoiding
abrupt steering maneuvers.

238 OperationTires and wheelsIf you wish to cancel activation:
Press
ç
button.
If the following message appears in the
speedometer display field:
Reactivate tire press. monit.


Re-start the activation of the tire infla-
tion pressure monitor.
If the following message appears in the
speedometer display field:
Tire pressure

Check tires!


Re-start the activation of the tire infla-
tion pressure monitor.
Rotating wheels
On vehicles with the same wheel size all
around, wheels can be rotated every 3000
to 6000 miles (5 000 to 10 000 km), or
sooner if necessary, according to the de-
gree of tire wear. The same direction of tire
rotation must be retained.
Rotate the wheels before the characteris-
tic tire wear pattern becomes visible
(shoulder wear on front wheels and tread
center wear on rear wheels).Thoroughly clean the inner side of the
wheels after each rotation. Check and en-
sure proper tire inflation pressure, activat-
ing the tire inflation pressure monitor if
necessary. Warning!
G
Rotate front and rear wheels only if they are
of the same size.
Warning!
G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
96 ft.lb. (130 Nm).
Only use genuine Mercedes-Benz wheel
bolts specified for your vehicle's rims.

312 Practical hintsFlat tireMounting the spare wheel Preparing the vehicle
Prepare the vehicle as described above
(
page 302).

Turn spare wheel bracket counter-
clockwise to loosen.

Take the wheel out of the trunk.
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 sur-
face:
Place one chock in front of and one
behind the wheel that is diagonally
opposite 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 storage compartment under
the trunk floor (
page 289).
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 mounted spare
wheel. Adapt your driving style accordingly.
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.
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack tubes built into
both sides of the vehicle. To help avoid per-
sonal injury, use the jack only to lift the ve-
hicle 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, es-
pecially on hills. Always try to use the jack
on level surface. Be sure that the jack arm is
fully inserted in the jack tube. Always lower
the vehicle onto sufficient capacity jack-
stands before working under the vehicle.

318 Practical hintsFlat tireLowering the vehicle
Lower vehicle by turning crank coun-
terclockwise until the full weight of the
vehicle is resting on the ground.

Pull the jack out of the jack support
tube.
1 - 5 Wheel bolts

Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to 5), until all bolts are tight.
Observe a tightening torque of 96 ft lb
(130 Nm).

Before storing the jack in the trunk,
crank back to storage position and fold
in the arm.Replacing jack support tube cover

Slide tongue of cover under the upper
edge of the tube opening.

Applying even pressure, press cover
until it snaps into place. Be careful not
to damage the locking tabs or clamp
the plastic retaining strap.
Warning!
G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
96 ft lb (130 Nm).
