Steel spare wheel rim
(E 320 without sport package)
Important!
Unidirectional tires must always be mounted with arrow
on tire sidewall pointing in direction of vehicle forward
movement.
If the arrow on tire side wall does not point in direction
of vehicle forward movement when using the spare
wheel, observe the following restrictions:
•Drive to the nearest tire repair facility as soon as
possible.
For rim and tire specifications, see page 313.

(E 320 with sport package, E 430)
Important!
The spare wheel rim is mounted with a full size tire of
the same type as on the vehicle, and is fully functional.
However, that spare wheel rim is weight optimized and
has a limited service life of 12 000 miles (20 000 km)
use before a standard wheel rim must replace it.
In the case of a f lat tire, you may temporarily use the
spare wheel.
Do not operate vehicle with more than one spare wheel
mounted.Unid irectional tires must a lways be mou nted w it h a rrow
on tire sidewall pointing in direction of vehicle forward
movement.
If the arrow on tire side wall does not point in direction
of vehicle forward movement when using the spare
wheel, observe the following restrictions:
•Drive to the nearest tire repair facility as soon as
possible.
For rim and tire specifications, see page 313.
Wa r n i n g !
The spare wheel rim is for temporary use only. Use
for over a total of 12 000 miles (20 000 km)
(aggregate off all uses) may cause wh eel rim failure
leading to an accident and possible injuries.

Spare wheel
(E 55 AMG)
The spare wheel rim size is 7
1/2 J x 17 H 2 with tire size
235 / 45 R 17 93 W.
Important!
In the case of a f lat tire or breakdown, you may
temporarily use the wheel when observing the following
restrictions:
•Do not exceed vehicle speed of 50 mph (80 km / h).
•Drive to the nearest repair facility to have the f lat
tire repaired or replaced as appropriate.
•Do not operate vehicle with more than one spare
wheel mounted.For rim and tire specifications, see page 313.

The spare wheel rim is for temporary use only. Use
for over a total of 12 000 miles (20 000 km)
(aggregate off all uses) may cause wh eel rim failure
leading to an accident and possible injuries.The dimensions of the spare wheel are different
from those of road wheels. As a result, the vehicle
handling characteristics change when driving with
a mounted spare wheel.The spare wheel should only be used temporarily,
and replaced with a regular road wheel as quickly
as possible.

Important!
E 320 (except sport package) only:
When installing steel spare wheel rim, make certain to
use the correct wheel bolts, supplied in the vehicle tool
kit, see page 268 and page 264.10. 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 f lat against hub
and hold it there while installing first wheel bolt.
Unscrew the alignment bolt (1) to install the last
wheel bolt.

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 th e sequ ence ill ustrated , until all bolts a re
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.Wa r n i n g !

Tire inflation pressure
A table (see fuel filler f lap) 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
warm tires only if pressure has dropped below the
pressure listed in the table and the respective operating
conditions are taken into consideration.
An underinf lated 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.

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 under the rear
seat cushion. To minimize the chance for acid leakage
which could cause severe burns during a crash or
rollover, a special acid leakage resistant battery was
factory installed. A replacement battery for the vehicle
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
cloth ing. In c ase it does, im mediately f lush affected
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..
