194 Controls in detailLoadingLoading instructions
The total load weight including vehicle oc-
cupants and luggage/cargo should not ex-
ceed the vehicle capacity weight indicated
on the certification tag which can be found
on the left door pillar.
The handling characteristics of a fully load-
ed vehicle depend greatly on the load dis-
tribution. It is therefore recommended to
load the vehicle according to the illustra-
tions shown, with the heaviest items being
placed towards the front of the vehicle.
Always place items being carried against
front or rear seat backrests, and fasten
them as securely as possible.The heaviest portion of the cargo should al-
ways be kept as low as possible since it in-
fluences the handling characteristics of
the vehicle.
Warning!
G
Always fasten items being carried as secure-
ly as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle and can cause in-
jury to vehicle occupants unless the items
are securely fastened in the vehicle.
To help avoid personal injury during a colli-
sion or sudden maneuver, exercise care
when transporting cargo.
Never drive vehicle with trunk lid open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in uncon-
sciousness and death.

235 Operation
Tires and wheels
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.
Tire temperature and tire pressure are also
increased while driving, depending on the
driving speed and the tire load.Check the spare tire periodically for condi-
tion and inflation. Spare tires will age and
become worn over time even if never used,
and thus should be inspected and replaced
when necessary.
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.
Warning!
G
Follow recommended inflation 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 pillar in the driver’s
door opening). Overloading the tires can
overheat them, possibly causing a blowout.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
80 ft.lb. (110 Nm).
Use only genuine Mercedes-Benz wheel
bolts specified for your vehicle's rims.

291 Practical hints
Flat tire

Unscrew the alignment bolt, install last
wheel bolt and tighten slightly.Lowering the vehicle

Lower vehicle by turning crank coun-
terclockwise until vehicle is resting ful-
ly on its own weight.

Remove the jack.
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 80 ft lb
(110 Nm).
!To avoid paint damage, place wheel flat
against hub and hold it there while in-
stalling first wheel bolt.Warning!
G
Always replace wheel bolts that are dam-
aged or rusted.
Never apply oil or grease to wheel bolts.
Damaged wheel hub threads should be re-
paired immediately. Do not continue to drive
under these circumstances! Contact an au-
thorized Mercedes-Benz Center or call
Roadside Assistance.
Incorrect mounting bolts or improperly
tightened mounting bolts can cause the
wheel to come off. This could cause an acci-
dent. Be sure to use the correct mounting
bolts.
Warning!
G
Use only genuine equipment
Mercedes-Benz wheel bolts. They are identi-
fied by the Mercedes star. Other wheel bolts
may come loose.
Do not tighten the wheel bolts when the ve-
hicle is raised. Otherwise the vehicle could
tip over.


293 Practical hints
Flat tire

To switch off the air pump turn the key
in the starter switch to position0
(page 31).

If the tire pressure is above 36 psi (2.5
bar), release excess tire pressure using
the vent screw.

Detach the electric air pump.

Store the electrical plug and the air
hose behind the flap and place the air
pump back in the trunk.
!Do not operate the electric air pump
longer than six minutes without inter-
ruption. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.
Warning!
G
Follow recommended inflation pressures.
Do not overinflate tires. Overinflated 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. Underinfalted 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.
