Soft top
Opening and closing the soft top
For safety reasons, the soft top can only be
opened and closed when the vehicle is
standing still.Warning!
G
Before operating the switch for the soft top,
make sure no persons can be injured by the
moving parts (roll bars, soft top frame, and
soft top compartment cover).
Hands must never be placed near the roll
bar, soft top frame, upper windshield area,
shelf behind roll bar, or soft top storage
compartment while the soft top is being
raised or lowered. Serious personal injury
may occur.
If potential danger exists, release the soft
top switch. This immediately interrupts the
raising or lowering procedure. You then can
operate the soft top switch to raise or lower
the soft top away from the danger zone.
Warning!
G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO
*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment can cause an accident
and/or serious personal injury.
!Never sit or place heavy objects on the
rear shelf. Doing so could cause dam-
age to the soft top and the rear shelf.
!When opening and closing the soft top,
make sure:
there is sufficient clearance for the
soft top to move up
the luggage cover is engaged in
place (
page 262)
the trunk is only loaded to the
height of the luggage cover
the luggage/cargo does not push
the closed luggage cover up
the trunk lid is closed
nothing is placed on the soft top

270 Controls in detailDriving systemsRange of the sensors
To function properly, the sensors must be
free of dirt, ice, snow and slush. Clean the
sensors regularly, being careful not to
scratch or damage the sensors, see
“Cleaning the Parktronic system*
(Canada only) sensors” (
page 369).
Front sensors
Rear sensorsMinimum distance
If the system detects an obstacle in this
range, all the distance warning segments
illuminate and you hear a warning signal. If
the obstacle is closer than the minimum
distance, the actual distance may no long-
er be indicated by the system.

!During parking maneuvers, pay special
attention to objects located above or
below the height of the sensors (e.g.
planters or trailer hitches). The
Parktronic system will not detect such
objects at close range and damage to
your vehicle or the object may result.
Ultrasonic signals from outside sourc-
es (e.g. truck air brakes, car wash, or
jackhammers) may impair the opera-
tion of the Parktronic system.

Loading
Loading instructions
The total load weight including vehicle oc-
cupants and luggage/cargo should not ex-
ceed the load limit or vehicle capacity
weight indicated on the corresponding
placard located on the driver’s door B-pillar
(page 333).
The handling characteristics of a fully load-
ed vehicle depend greatly on the load dis-
tribution. It is therefore recommended to
load the heaviest items being placed to-
wards the front of the vehicle.
Always place items being carried against
rear seat backrests, and fasten them as se-
curely as possible.
The heaviest portion of the cargo should al-
ways be kept as low as possible since it in-
fluences the handling characteristics of
the vehicle.
!To prevent damage to the soft top or
luggage/cargo when lowering the roof:
load trunk only to the height of the
luggage cover
do not permit luggage/cargo to
push up the closed luggage cover
do not place anything on the shelf
behind the roll bar
do not place anything on the soft
top compartment cover
Warning!
G
Always fasten items being carried as secure-
ly as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle and can cause in-
jury to vehicle occupants unless the items
are securely fastened in the vehicle.
To help avoid personal injury during a colli-
sion or sudden maneuver, exercise care
when transporting cargo. Put luggage or car-
go in the trunk if possible.
Never drive vehicle with trunk open. Deadly
carbon monoxide (CO) gases may enter ve-
hicle interior resulting in unconsciousness
and death.

Cup holdersWarning!
G
In order to help prevent spilling liquids on
vehicle occupants and/or vehicle equip-
ment, only use containers that fit into the
cup holder. Use lids on open containers and
do not fill containers to a height where the
contents, especially hot liquids, could spill
during braking, vehicle maneuvers, or in an
accident. Liquids spilled on vehicle occu-
pants may cause serious personal injury.
Liquids spilled on vehicle equipment may
cause damage not covered by the
Mercedes-Benz Limited Warranty
When not in use, keep the cup holder
closed. An open cup holder may cause injury
to you and others when contacted during
braking, vehicle maneuvers, or in an
accident.

!To avoid damage to the windshield wip-
ers or hood, never open the hood if the
wiper arms are folded forward away
from the windshield.
Warning!
G
To help prevent personal injury, stay clear of
moving parts when the hood is open and the
engine is running. Make sure the hood is

322 OperationEngine compartment
Closing
Let the hood drop from a height of
approximately 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
the vehicle is new
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
(ignition coils, spark plug sockets, diagnos-
tic socket) of the ignition system
with the engine running
while starting the engine
if ignition is “on” and the engine is
turned manually
Warning!
G
Be careful that you do not close the hood on
anyone.
iDo not use any special lubricant addi-
tives, as these may damage the drive
assemblies. Using special additives not
approved by Mercedes-Benz may
cause damage not covered by the
