(Model C 230 Kompressor)

The system is always at operational readiness, except when manually switched off. The climate control only
operates with the engine running. To quickly cool down the passenger compartment, turn temperature
selectors fully downward. Turn temperature selector to maintain desired temperature. The climate control removes
considerable moisture from the air during operation in the cooling mode. It is normal for water to drip on the ground
through ducts in the underbody.

turn off the defroster as soon as the window is clear.
The defroster is automatically turned off after a maximum of 12 minutes of operation.
If several power consumers are turned on simultaneously, or the battery is only partially charged, it is possible
that the defroster will automatically turn itself off. When this happens, the indicator lamp inside the switch starts
blinking. As soon as the battery has sufficient voltage, the defroster automatically turns itself back on.

The system is always at operational readiness, except when manually
switched off. The automatic climate control only operates with the engine
running. The temperature selector should be left at the desired temperature
setting.
The temperature selected is reached as quickly as possible. The system
will not heat or cool any quicker by setting a higher or lower temperature.

Steering Lock

0 - The electronic key can be withdrawn in this position only. The steering is locked with the electronic key removed
from the steering lock. The electronic key an be removed only with the selector lever in position "P" and the foot off
the brake pedal. After removing the electronic key or with the electronic key in steering lock position 0, the
selector lever is locked in position "P".
1 - Steering is unlocked. (If necessary, move steering wheel slightly to allow the electronic key to be turned clockwise
to position 1.) Most electrical consumers can be operated. For detailed information see respective subjects.
2 - Driving position.
3 - Starting position.

Refer to Index for Starting and turning off the engine.


Warning !
When leaving the vehicle always remove the electronic key from the steering lock, and lock the vehicle.
Do not leave children unattended in the vehicle, or with access to an unlocked vehicle.
Unsupervised use of vehicle equipment may cause serious personal injury.


Important !
If the electronic key is left in the steering lock position 0 for an extended period of time, it can no longer be turned
in the lock. In this case, remove electronic key from steering lock and reinsert.

Notes:
A warning sounds when the driver's door is opened with the electronic key in steering lock position 1 or 0. With the
engine at idle speed, the charging rate of the alternator (output) is limited. It is therefore recommended to turn off
unnecessary electrical consumers while driving in stop-and-go traffic. This precaution helps to avoid draining of the
battery. Unnecessary strain on the battery and charging system may be minimized by turning off the following power
consumers, for example: Heated seats, rear window defroster. In addition, the automatic climate air volume control
should be set to the lowest position. The steering lock can only be unlocked with the vehicle battery properly
connected.

Caution !
To prevent accelerated battery discharge and a possible dead battery, always remove the electronic key from the
steering lock. Do not leave the electronic key in steering lock position 0.

Wiper Blade
Clean the wiper blade rubber with a clean cloth and detergent solution. Replace blade twice a year;
once before and once after winter.


Headlamp Cleaning System
The condition of the wiper blades is important fo r satisfactory cleaning of the headlamp lenses.
We therefore recommend that the blades be insp ected regularly. Replace damaged wiper blades.


Paintwork. Painted Body Components
Mercedes-Benz approved Paint Care should be a pplied 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 ap plied if paint surface shows signs of dirt
embedding
(i.e. loss of gloss).
Do not apply any of these products or wax if your car 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, car doors etc.).


Seat Belts
The webbing must not be treated with chemical cleaning agents. Use only clear, lukewarm water
and soap. Do not dry the webbing at temperatures above 176°F (80°C) or in direct sunlight.

Warning !
Do not bleach or dye seat belts as this may severely weaken them. In a crash they
may not be able to provide adequate protection.


Hard Plastic Trim Items
Pour Mercedes-Benz approved Interior Care onto so ft lint-free cloth and apply with light pressure.


Headliner and Shelf below Rear Window
Clean with soft bristle brush, or use a dry- shampoo cleaner in case of excessive dirt.


Plastic and Rubber Parts
Do not use oil or wax on these parts.


Steering Wheel and Gear Selector Lever
Wipe with a damp cloth and dry thoroughly or clean with Mercedes-Benz approved Leather Care.


Light Alloy Wheels
Mercedes-Benz approved Wheel Care should be used for regular cleaning of the light alloy wheels.
If possible, clean wheels once a week with Merc edes-Benz approved Wheel Care, using a soft
bristle brush and a strong spray of water. Follow instructions on container.

Note:
Use only acid-free cleaning materials. The acid could lead to corrosion.


Ornamental Moldings
For regular cleaning and care of very dirty chrome-plated parts, use a chrome cleaner.

Consumer Information

This has been prepared as required of all manufacturers of passenger cars under Title 49, Code of U.S. Federal
Regulations, Part 575 pursuant to the "National Traffic and Motor Vehicle Safety Act of 1966".

Uniform Tire Quality Grading
Refer to the tire sidewall for the specific tire grades for t he tires with which this vehicle is equipped. All passenger car
tires must conform to federal safety requirements in addition to these grades.

Treadwear
The treadwear grade is a comparative rating based on t he wear rate of the tire when tested under controlled
conditions on a specified government test course. For ex ample, a tire graded 150 would wear one and one-half (11/2)
times as well on the government course as a tire grad ed 100. The relative performance of tires depends upon the
actual conditions of their use, however, and may depart signi ficantly from the norm due to variations in driving habits,
service practices and differences in road characteristics and climate.

Traction
The traction grades, from highest to lowest, are AA, A, B, and C, Those grade represent the tire's ability to stop on
wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and
concrete. A tire marked "C" ma y have poor traction performance.

Warning !
The traction grade assigned to this tire is based on straight-ahead braking traction tests and does not
include cornering, hydroplaning or peak traction characteristics.

Temperature
The temperature grades are A (the highest), B, and C, representing the tire's resistance to the generation of heat and
its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The grade C co rresponds to a level of performance which all passenger
car tires must meet under the Federal Motor Vehicle Safety Standard No.109. Grades B and A represent higher
levels of performance on the laboratory test wheel than the minimum required by law.

Warning !
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause
excessive heat build up and possible tire failure.
