242 Controls in detailLoadingSetting up rear seat bench
Fold backrest4 rearward until it en-
gages.
Fold seat cushions3 rearward until it
locks into position.
If a backrest is not locked into position, a
red indicator5 or6 will be visible.
Check for secure locking by pushing
and pulling on the backrest.
Loading 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.
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 ex-
tended trunk 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 colli-
sion or sudden maneuver, exercise care
when transporting cargo.iTo prevent unauthorized persons from
access to the trunk, always lock back-
rest in its upright position.

292 OperationTires and wheelsChecking tire inflation pressure
Correct the tire pressure only when tires
are cold.
Regularly check your tire pressure at inter-
vals of no more than 14 days.
If the tires are warm you should only cor-
rect the tire pressure if it is too low for cur-
rent operating conditions.
A table on the fuel filler flap lists the spec-
ified tire inflation pressures for warm and
cold tires as well as for various operating
conditions.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
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.Warning!
G
If the tire pressure drops repeatedly:
Check the tires for punctures from for-
eign objects.
Check to see whether air is leaking from
the valves or from around the rim.
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. 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.

362 Practical hintsFlat tire
Unscrew the alignment bolt, install last
wheel bolt and tighten slightly.Lowering the vehicle
Lower vehicle by turning crank coun-
terclockwise until the full weight of the
vehicle is resting on the ground.
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 lb-ft
(110 Nm).
Before storing the jack in the trunk, it
should be fully collapsed, with handle
folded in.
Warning!
G
Only use genuine equipment
Mercedes-Benz wheel bolts. Other wheel
bolts may come loose.
Do not tighten the wheel bolts when the ve-
hicle is raised. Otherwise the vehicle could
tip over.
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).
