Let the hood drop from a height of ap-
proximately 1 ft (30 cm).

The hood will lock audibly.

Check to make sure the hood is fully
closed.

If you can raise the hood at a point
above the headlamps, then it is not
properly closed. Open it again and let it
drop with somewhat greater force.

Engine oil

The amount of oil your engine needs will
depend on a number of factors, including
driving style. Higher oil consumption can
occur when

앫

the vehicle is new

앫

the vehicle is driven frequently at
higher engine speeds

Engine oil consumption checks should only
be made after the vehicle break-in period.

Warning!

G

If you see flames or smoke coming from the
engine compartment, or if the coolant tem-
perature 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 the fire department.

Warning!

G

The engine is equipped with a transistorized
ignition system. Because of the high voltage
it is dangerous to touch any components (ig-
nition coils, spark plug sockets, diagnostic
socket) of the ignition system

앫

with the engine running

앫

while starting the engine

앫

if ignition is “on” and the engine is
turned manually

Warning!

G

Be careful that you do not close the hood on
anyone.

!

Do not push the hood closed manually,
as this could damage it.

i

Do not use any special lubricant addi-
tives, as these may damage the drive
assemblies. Using special additives not
approved by Mercedes-Benz will
restrict your warranty entitlement.
