vehicle tool kit and assemble (see page 305).
6. Using the wrench, loosen but do not yet remove the
wheel bolts.7. Place jack on firm ground. Position jack (1) under
the take-up bracket (2) so that it is always vertical
(plumb-line) as seen from the side, even if the
vehicle is parked on an incline.
The jack take-up brackets are located directly
behind the front wheel housings and in front of the
rear wheel housings.
8. Jack up the vehicle until the wheel is clear of the
ground. Never start engine while vehicle is raised.

9. 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.
10. Remove wheel. Grip wheel from the sides. Keep
hands from beneath the wheels.1Wheel bolt for light alloy rims

Install spare 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 to install the last wheel
bolt.12. Lower vehicle and remove jack.

13. 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).14. Vehicles with steel rims
Installation of wheel cover:
Position small wheel cover opening over tire valve
and press wheel cover against wheel rim. Now press
(do not hit) opposite side of wheel cover against
wheel rim until seated. Make certain that the
springs of the wheel cover are firmly seated in the
outer rim of the steel wheel.

Before storing the jack, it should be fully collapsed, with
handle folded in.
For proper storage of vehicle jack see page 304.Tire inflation pressure
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).
Tire pressures listed for light loads are minimum values
offering high driving comfort. Increased inflation
pressures for heavy loads produce favorable handling
characteristics with lighter loads and are perfectly
permissible. The ride of the vehicle, however, will
become somewhat harder.
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
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.

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.Battery
Important!
Battery replacement information:
The maintenance-free battery is located in the engine
compartment on the right hand side.
The service life of the battery is dependent on its
condition of charge. The battery should always be kept
sufficiently charged, in order to last an optimum length
of time.
Wa r n i n g !
Do not overinflate tires. Overinflating tires can
result in sudden deflation (blowout) because they
are more likely to become punctured or damaged
by road debris, potholes etc. Follow recommended
inflation pressures.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.
Wa r n i n g !
Failure to follow these instructions can result in
severe injury or death.Never lean over batteries while connecting, you
might get injured.Battery fluid contains sulfuric acid. Do not allow
this fluid to come in contact with eyes, skin or
clot hin g. In cas e i t d oes , i mm ed ia tely f lus h a f fected
area with water and seek medical help if necessary.A battery will also produce hydrogen gas, which is
flammable and explosive. Keep flames or sparks
away from battery, avoid improper connection of
jumper cables, smoking etc.

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.
Ad d ition al in fo rm atio n can be foun d in t he boo klet titled
“Vehicle Care Guide”.
Power washer
When using a power washer for cleaning the vehicle
always observe manufacturer’s 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.).
