stop. Place jack on firm ground. Position the jack so
that it is always vertical (plumb-line) as seen from
the side (see arrow), especially if the vehicle is
parked on an incline.
9. Jack up the vehicle until the wheel is clear of the
ground. Never start engine while vehicle is raised.
10. 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.11. Remove wheel. Grip wheel from the sides. Keep
hands from beneath the wheels.
12. Clean contact surfaces of wheel and wheel hub.
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 (1) to install the last
wheel bolt.

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 approx. 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 = approx. +68°F (+20°C) and
ambient temperature = approx. +32°F (0°C) then the
adjusted air pressure = specified air pressure +3psi
(+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

Do not drive the vehicle while the wheel change
switch is activated since the vehicle suspension
will not function properly.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) may
cause wheel rim failure leading to an accident and
possible injuries. Vehicles with Sport Package:
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.

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 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 !
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.

Important!
Battery replacement information:
The maintenance-free battery is located in the trunk
behind the right side cover panel.
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.Therefore, we strongly recommend that you have the
battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than
approximately 200 miles (300 km) per month,
mostly for short distance trips, or if it is not used for
long periods of time.
Only charge a battery with a battery charger after the
battery has been disconnected from the vehicle’s
electrical circuit.
Always disconnect the battery negative lead first and
connect last.
When removing and connecting the battery, always
make sure that all electrical consumers are off and the
key is in steering lock position 0. The battery must
always be securely installed when the vehicle is in
operation. During removal and installation always
protect the disconnected battery positive (+) terminal
with the cover attached to the battery.
While the engine is running the battery terminal clamps
must not be loosened or detached, otherwise the
generator and other electronic components will be
damaged.
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
clothing. In case it does, immediately flush affected
area with water and seek medical help.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.

Important!
Do not close a door with the windows fully closed while
the power supply is interrupted (battery disconnected or
empty).
Doing so could damage the window frame.
Note:
After reconnecting the battery also set the clock,
resynchronize the express feature of the power
windows, the electronic stability program (ESP) and the
adaptive damping System (ADS).
See page 79 for setting clock, page 41 for power
windows, page 193 for ESP and page 199 for ADS. Battery Recycling
Batteries contain materials that can harm the
environment with improper disposal.
Large 12 Volt storage batteries contain lead.
Recycling of batteries is the preferred method of
disposal.
Many states require sellers of batteries to accept old
batteries for recycling.

A major concern among engine manufacturers is carbon
build up caused by gasoline. Mercedes-Benz
recommends the use of only quality gasoline containing
additives that prevent the build up of carbon deposits.
After an extended period of using fuels without such
additives, carbon deposits can build up especially on the
intake valves and in the combustion area, leading to
engine performance problems such as:
• warm-up hesitation,
•unstable idle,
•knocking/pinging,
•misfire,
• power loss.
Do not blend other specific fuel additives with fuel.
They only result in unnecessary cost, and may be
harmful to the engine operation.
Damage or malfunctions resulting from poor fuel
quality or from blending specific fuel additives are not
covered by the Mercedes-Benz Limited Warranty.Coolants
The engine coolant is a mixture of water and
anticorrosion/antifreeze, which provides:
• corrosion protection,
• freeze protection,
• boiling protection (by increasing the boiling point).
The cooling system was filled at the factory with a
coolant providing freeze protection to approximately
-22°F (-30°C) and corrosion protection.
If the antifreeze mixture is effective to -22°F (-30°C), the
boiling point of the coolant in the pressurized cooling
system is reached at approx. 266°F (130°C).
The coolant solution must be used year round to provide
the necessary corrosion protection and increase in the
boil-over protection. You should have it replaced every
3years.
To provide the important corrosion protection, the
solution must be at least 45% anticorrosion/antifreeze
(equals a freeze protection to approx. - 22°F [-30°C]). If
you use a solution that is more than 55% anticorrosion/
antifreeze (freeze protection to approx. - 49°F [-45°C]),
