232 Controls in detailLoading
Loading instructions
The total load weight including vehicle oc-
cupants and luggage/cargo should not ex-
ceed the vehicle capacity weight indicated
on the corresponding label located on the
driver’s 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
If a red indicator is visible with the backrest
up, then the backrest is not properly locked
into position.
Always lock backrest in its upright position
when rear seat bench is occupied, or the
extended cargo compartment is not in use.
Check for secure locking by pushing and
pulling on the backrest.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and cause injury
to vehicle occupants unless the items are
securely fastened in the vehicle.
To help avoid personal injury during a
collision or sudden maneuver, exercise care
when transporting cargo.

280 OperationTires and wheels
Tire pressure changes by approx. 1.5 psi
(0.1 bar) per 18°F (10°C) of air tempera-
ture change. Keep this in mind when
checking tire pressure where the tempera-
ture is different from the outside tempera-
ture.
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
b e c o m e w o r n o v e r t i m e e v e n i f n e v e r u s e d ,
and thus should be inspected and replaced
when necessary.
iThe pressures listed for light loads are
minimum values offering high driving
comfort.
Increased inflation pressures listed for
heavier loads may also be used for light
loads. These higher pressures produce
favorable handling characteristics. The
ride of the vehicle, however, will be
somewhat harder. Never exceed the
max. values or inflate tires below the
min. values listed in the fuel filler flap.
Warning!
G
Follow recommended inflation pressures.
Do not overinflate tires. Overinflated tires
can result in sudden deflation (blowout)
because they are more likely to become
punctured 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 indi-
cated by the label on the pillar in the driver’s
door opening). Overloading the tires can
overheat them, possibly causing a blowout.

346 Practical hintsFlat tire
Unscrew the alignment bolt, install last
wheel bolt and tighten slightly.Lowering the vehicle
Lower vehicle by turning crank
counterclockwise until vehicle is
resting fully on its own weight.
Remove the jack.
1 - 5Wheel bolts
Tighten the five wheel bolts evenly,
following the diagonal sequence
illustrated (1to5), until all bolts are
tight. Observe a tightening torque
of 80 lb-ft (110 Nm).Before storing the jack, it should be fully
collapsed, with handle folded in (storage
position) (
page 322).
Store the jack and the other vehicle
tools in the storage compartment be-
hind the left trim panel (
page 322).
Warning!
G
Only use genuine equipment
Mercedes-Benz wheel bolts. Other wheel
bolts may come loose.
Do not tighten the wheel bolts when the
vehicle is raised. Otherwise the vehicle
could fall of the jack.
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 80 lb-ft (110 Nm).
