not yet remove the wheel bolts.5. Remove the protective cover from the jack support
tube opening by inserting the screwdriver (supplied
in the tool kit) in the opening and prying it out.
The tube openings are located directly behind the
front wheel housings and in front of the rear wheel
housings.

6. Insert jack arm fully into the tube hole up to the
stop. Place jack on firm ground. Position the jack so
that it is always vertical (plumb-line) as seen from
the side (see arrow), even if the vehicle is parked on
an incline.
7. Jack up the vehicle until the wheel is clear of the
ground. Never start engine while vehicle is raised.8. Unscrew upper-most wheel bolt and install
alignment bolt (1) supplied in the tool kit. Remove
the remaining bolts. Keep bolt threads protected
from dirt and sand.
9. Remove wheel. Grip wheel from the sides. Keep
hands from beneath the wheels.

When installing steel spare wheel rim, make certain to
use the correct wheel bolts, supplied in the vehicle tool
kit, see page 281 and page 277.10. Clean contact surfaces of wheel and wheel hub.
Install wheel on wheel hub. Insert wheel bolts and
tighten them slightly.
To avoid paint damage, place wheel flat against hub
and hold it there while installing first wheel bolt.
Unscrew the alignment bolt (1) to install the last
wheel bolt.

11. Lower vehicle. Remove jack and insert jack tube
cover.
Before storing the jack, the jack arm must be
lowered almost to the base of the jack.
12. Using the wrench, tighten the five bolts evenly,
following the sequence illustrated, until all bolts are
tight.
Observe a tightening torque of 80 ft.lb. (110 Nm).
13. Ensure proper tire pressure.

Wa r n i n g !
Always replace wheel bolts that are damaged or
rusted.Never apply oil or grease to wheel bolts.Damaged wheel hub threads should be repaired
immediately.Incorrect mounting bolts or improperly tightened
mounting bolts can cause the wheel to come off.
This could cause an accident. Be sure to use the
correct mounting bolts.

A table (see fuel filler flap) lists the tire inflation
pressures specified for Mercedes-Benz recommended
tires as well as for the varying operating conditions.
Important!
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 inside a garage -
especially in the winter.
Example:
If garage temperature = approximately +68
°F (+20
°C)
and ambient temperature = approximately +32
°F (0
°C)
then the adjusted air pressure = specified air pressure
+3 psi (+0.2 bar).The 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.
Tire temperature and pressure increase with the vehicle
speed. Tire pressure should therefore only be checked
and corrected on cold tires. Correct tire pressure in
warm tires only if pressure has dropped below the
pressure listed in the table and the respective operating
conditions are taken into consideration.
An underinflated tire due to a slow leak (e.g. due to a
nail in the tire) may cause damage such as tread
separation, bulging etc.. Regular tire pressure checks
(including the spare tire) at intervals of no more than
14 days are therefore essential.

If a tire constantly loses air, it should be inspected for
damage.
The spare tire should be checked periodically for
condition and inflation. Spare tire will age and become
worn over time even if never used, and thus should be
inspected and replaced when necessary.
Wa r n i n 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 indicated by the label
on the driver’s door latch post). Overloading the
tires can overheat them, possibly causing a
blowout.

315 Cleaning and care of the vehicle
Te ch n i c a l

cluster displayPractical hintsCar careIndex Scratches, corrosive deposits, corrosion or damage due
to negligent or incorrect care cannot always be removed
or repaired with the car-care products recommended
here. In such cases it is best to seek aid at your
authorized Mercedes-Benz Center.
The following topics deal with the cleaning and care of
your vehicle and give important “how-to” information as
well as references to Mercedes-Benz approved car-care
products.
Additional information can be found in the booklet titled
“Vehicle Car Guide”.
Power washer
When using a power washer for cleaning the vehicle
always observe manufacturers’ operating instructions.
Caution!
Never use a round nozzle to power wash tires. The
intense jet of water can result in damage to the tire.
Always replace a damaged tire.
Always keep the jet of water moving across the surface.
Do not aim directly at electrical parts, electrical
connectors, seals, or other rubber parts.Tar st ai ns
Quickly remove tar stains before they dry and become
more difficult to remove. A tar remover is
recommended.
Paintwork, painted body components
Mercedes-Benz approved Paint Care should be applied
when water drops on the paint surface do not “bead up”,
normally in 3 to 5 months, depending on climate and
washing detergent used.
Mercedes-Benz approved Paint Cleaner should be
applied if paint surface shows signs of dirt embedding
(i.e. loss of gloss).
Do not apply any of these products or wax if your
vehicle is parked in the sun or if the hood is still hot.
Use the appropriate MB-Touch-Up Stick for quick and
provisional repairs of minor paint damage (i.e. chips
from stones, vehicle doors etc.).
