Antitheft Alarm System

1. Indicator lamp in switch located in center console

The antitheft alarm is automatically armed or disarmed with the remote
control or any of your vehicle's mechanical keys by locking or unlocking the driver's door or the trunk.
A blinking lamp (1) indicates that the alarm is armed.

Operation
Once the alarm system has been armed, the exterior vehicle lamps will flash and the horn will sound
intermittently when someone:
• opens a door,
• opens the trunk,
• opens the hood,
• attempts to raise the vehicle.
The alarm will last approximately 21/2 minutes in the form of blinking exterior lamps. At the same time an alarm will
sound for 30 seconds.
The alarm will stay on even if the activating element (a door, for example) is immediately closed.

Note:
We recommend that you carry the electronic reserve key with mechanical key with you and keep it in a safe place
(e.g. your wallet) so that it is always handy. Never leave the electronic reserve key in the vehicle.

Outside Temperature Indicator
The temperature sensor is located in the front bumper area. Due to its location, the sensor can be affected by road or
engine heat during idling or slow driving. This means that the accuracy of the displayed temperature can only be
verified by comparison to a thermometer placed next, to the sensor, not by comparison to external displays (e.g. bank
signs etc.).
Adaptation to ambient temperature takes place in steps and depends on the prevailing driving conditions (stop-and-
go or moderate, constant driving) and amount of temperature change.

Warning !
The outside temperature indicator is not designed to serve as an Ice-Warning Device and is therefore
unsuitable for that purpose. Indicated temperatures just above the freezing point do not guarantee that the
road surface is free of ice.


Coolant Temperature Gauge
If the antifreeze mixture is effective to -22°F (-30°C), the boiling point of the c oolant in the pressurized cooling system
of your vehicle is approx. 266°F (130°C). During severe operating conditions and stop-and-go city traffic, the coolant
temperature may rise close to the red marking. The engine should not be operated with the coolant temperature in
the red zone. Doing so may cause serious engine damage wh ich is not covered by the Mercedes-Benz Limited
Warranty.

Warning !
• Driving when your engine is badly overheated can cause some fluids which may
have leaked into the engine compartment to catch fire. You could be seriously burned.
• Steam from an overheated engine can cause serious burns and can occur just by opening
the engine hood. Stay away from the engine if you see or hear steam coming from it.

Turn off the engine, get out of the vehicle and do not stand near the car until it cools down.

Hood






To open:
To unlock the hood, pull release lever (1) under the driver's side of the instrument panel. At the same time handle
(2) will extend out of the radiator grill (it may be necessary to lift the hood up slightly).

Caution !
To avoid damage to the windshield wiper or hood, open the hood only with wiper in the parked position. Pull handle
(2) completely out of radiator grill and open hood (do not pull up on handle).

To close:
Lower hood and let it drop into lock from a height of approx. 1 ft. (30 cm), assisting with hands placed flat on edges
of hood (3). To avoid hood damage, if hood is not fully closed, repeat closing procedure. Do not push down on hood
to attempt to fully close it.

Warning!

To help prevent personal injury, stay clear of moving parts when the hood is open and the engine is running.
Be sure the hood is properly closed before driving. When closing hood, use extreme caution not to catch
hands or fingers. The engine is equipped with a transistorized ignition system. Because of the high voltage it
is dangerous to touch any components (ignition coils, spark plug sockets, diagnostic socket) of the ignition
system
• with the engine running,
• while starting the engine,
• if ignition is "on" and the engine is turned manually.
If you see flames, steam or smoke coming from the engine compartment, or if the coolant temperature
gauge indicates that the engine is overheated, do not open the hood. Move away from vehicle and do not
open the hood until the engine has cooled. If necessary, call a fire department.

Example



Checking Coolant Level
To check the coolant level, the vehicle must be parked on level ground and the engine stopped.
Check coolant level only when coolant is cold.
The coolant level should reach the black top part of the reservoir.


Adding Coolant
If coolant has to be added, a 50/50 mixture of water and MB anticorrosion/antifreeze should be added. The drain
plugs
for the cooling system are located on the right side of the engine block and at the bottom of the radiator.
Anticorrosion/antifreeze, see Coolants in Index.

Warning!
In order to avoid possibly serious burns or injury:
•Use extreme caution when opening the hood if there are any signs of steam or coolant leaking from the
cooling system, or if the coolant temperature gauge indicates that the coolant is overheated.
•Do not remove pressure cap on coolant reservoir if engine temperature is above 194°F (90°C). Allow
engine to cool down before removing cap. The coolant reservoir contains hot fluid and is under pressure.

•Using a rag, slowly open cap approximately 1/2 turn to relieve excess pressure. If opened immediately,
scalding hot fluid and steam will be blown out under pressure.

•Do not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes
into contact with hot engine parts.

Adjusting Headlamp Aim (Halogen)











Correct headlamp adjustment is
extremely important. To check and
readjust a headlamp follow steps 1
through 7. Please note:
• Horizontal aim will change and
must be corrected as described
below, whenever a vertical
adjustment is made.
• Low beam adjustments
simultaneously aim the high
beam and fog lamp.
• Vehicle should have a normal
trunk load.


1. Park vehicle on level surface approximately 25 ft. (7.6 m)
from a vertical test screen or wall. The centerline of the
vehicle must be at a 90° angle to the test screen.
2. (low beams on):
Using a carpenter's level, align and mark a vertical centerline
(8) on the test screen using the vertex of the angle formed in
each beam image. As a check, the distance between centerlines
should be 47 1/4 inches (1198 mm). If the distance does not check,
have the system verified at an authorized Mercedes-Benz dealer.
3. Open hood, depress latch (1), and remove access cover (2) from
the headlamp.
4. Vertical headlamp aim
(low beams on): Turn adjusting screw (3) (counterclockwise to adjust
headlamp downward, clockwise upward) until bubble in the level (4) is
centered on the "0" mark.
Graduations: 0.18° pitch.



5. Horizontal headlamp aim (low beams on):
Turn adjusting screw (5) (Right front headlamp: counterclockwise
to adjust to the left, clockwise to the right; left front head-
lamp: counterclockwise to adjust to the right, clockwise to the
left.) until the headlamps (low beam) illuminate the test screen
as shown. The vertex of the angle formed in each beam
image should align with the vertical centerline (8) of each lamp.
The left and right headlamps must be adjusted individually.
6. The indicator (6) in the sight glass should align with the
"0" mark after any horizontal adjustment. If it does not, slide
the "0" mark on the scale (7) until it aligns with the indicator (6).
Graduations: 0.38° pitch.
7. Reinstall access cover(2).

Note:
If it is not possible to obtain a proper headlamp adjustment, have
the system checked at your authorized Mercedes-Benz dealer.
