the minimum level.
When this occurs, the warning will first
come on intermittently and then stay on if
the oil level drops further.If no oil leaks are noted, continue to drive
to the nearest service station where the
engine oil should be topped to the required
level with an approved oil specified in the
Factory Approved Service Products pam-
phlet.

425 Practical hints
Flat tire
Flat tire
In the case of a flat tire, you may tempo-
rarily use the spare wheel when observing
the following restrictions:

Do not exceed a vehicle speed of
50 mph (80 km / h).


Drive to the nearest tire repair facility
to have the flat tire repaired or re-
placed as appropriate.


Do not operate vehicle with more than
one spare wheel mounted.
Preparing the vehicle
Park the vehicle as far as possible from
moving traffic on a hard surface.

Turn on the hazard warning flashers.

Engage the steering wheel lock in the
straight-ahead position and set the
parking brake.

Move the selector lever toP.

Have any passenger exit the vehicle at
a safe distance from the roadway.
Mounting the spare wheel
Preparing the vehicle
Prepare the vehicle as described under
“Preparing the vehicle” on this page.
Take the spare wheel out of the trunk
(page 407).

Take the wheel wrench and the jack
out of the trunk (
page 407).
Lifting the vehicle

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
(not included) or other sizable objects.
When changing wheel on a level surface:

Place one chock in front of and one be-
hind the wheel that is diagonally oppo-
site to the wheel being changed.
Warning!
G
The dimensions of the Minispare wheel and
the collapsible tire are different from those
of the road wheels. As a result, the vehicle
handling characteristics change when driv-
ing with a spare wheel mounted.
The spare wheel should only be used tempo-
rarily, and replaced with a regular road
wheel as quickly as possible.

426 Practical hintsFlat tireWhen changing wheel on a hill:
Place chocks on the downhill side
blocking both wheels of the other axle.

On wheel to be changed, loosen but do
not yet remove the wheel bolts (ap-
proximately one full turn with wrench). The jack take-up brackets are located di-
rectly behind the front wheel housing and
in front of the rear wheel housing.
1Jack take-up bracket
2Jack
3Crank

Position jack2 on firm ground under
the respective jack take-up bracket1.
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into either side of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on level surface. Be sure that the jack arm is
fully seated in the jack take-up bracket. Al-
ways lower the vehicle onto sufficient ca-
pacity jackstands before working under the
vehicle.

467 Technical data
Fuels, coolants, lubricants etc.
If the antifreeze mixture is effective to
-22°F (-30°C), the boiling point of the cool-
ant in the pressurized cooling system is
reached at approximately 266°F (130°C).
The coolant solution must be used
year-round to provide the necessary corro-
sion protection and increase boil-over pro-
tection. Refer to Maintenance Booklet for
replacement interval.
Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the
Maintenance Booklet is only applicable if
MB 325.0 anticorrosion/antifreeze solu-
tion or other Mercedes-Benz approved
products of equal specification (see
Factory Approved Service Products pam-
phlet) are used to renew the coolant con-
centration or bring it back up to the proper
level. To provide important corrosion protection,
the solution must be at least 45% anticor-
rosion/antifreeze [equivalent to freeze
protection to approximately - 22°F
(-30°C)]. If you use a solution that is more
than 55% anticorrosion/antifreeze [freeze
protection to approximately - 49°F
(-45°C)], the engine temperature will in-
crease due to the lower heat transfer capa-
bility of the solution. Therefore, do not use
more than this amount of anticorro-
sion/antifreeze.If the coolant level is low, water and
MB 325.0 anticorrosion/antifreeze should
be used to bring it up to the proper level
(have cooling system checked for signs of
leakage). Please make sure the mixture is
in accordance with label instructions.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water. If you
are not sure about the water quality, con-
sult your authorized Mercedes-Benz
Center.
Anticorrosion/antifreeze
Your vehicle contains a number of alumi-
num parts. The use of aluminum compo-
nents in motor vehicle engines
necessitates that anticorrosion/antifreeze
coolant used in such engines be specifical-
ly formulated to protect the aluminum
parts. (Failure to use such anticorro-
sion/antifreeze coolant will result in a sig-
nificantly shortened service life.)
