Memory function*
 Memory function*
You can store up to three different settings
per SmartKey.
The following settings are saved for each
stored position:

Driver’s seat, backrest and head
restraint position


Steering wheel position


Exterior rear view mirror positions
These key-dependent memory settings
can be deactivated if desired. For informa-
tion on key-dependent memory settings,
see “Setting key-dependency”
(
page 149). The following settings are not
key-dependent. They are stored when
using the buttons on the passenger door:


Front passenger seat, backrest and
head restraint position.
!Prior to operating the vehicle, the driv-
er should check and adjust the seat
height, seat position fore and aft, and
seat backrest angle if necessary, to en-
sure adequate control, reach and com-
fort. The head restraint should also be
adjusted for proper height. See also the
section on air bags (
page 61) for
proper seat positioning.
In addition, adjust the steering wheel to
ensure adequate control, reach, opera-
tion and comfort. Both the interior and
exterior rear view mirrors should be ad-
justed for adequate rear vision.
Fasten seat belts. Infants and small
children should be seated in a properly
secured restraint system that complies
with U.S. Federal Motor Vehicle Safety
Standards 213 and 225 and Canadian
Motor Vehicle Safety Standards 213
and 210.2.
Warning!
G
Do not activate the memory function while
driving. Activating the memory function
while driving could cause the driver to lose
control of the vehicle.

256 Controls in detailUseful featuresCup holders in front of seat armrestUnderneath the swiveling cup holder is
another stationary cup holder. You can
only use this when the swiveling cup holder
is pulled out and completely turned
outward.
Sliding out the swiveling cup holder

Press button1.
The cup holder slides upward. Turning the swiveling cup holder
outward

Turn the cup holder in the direction of
arrow
2 until it engages.
You can now use both cup holders.
Warning!
G
In order to help prevent spilling liquids on
vehicle occupants, only use containers that
fit into the cup holder. Use lids on open con-
tainers and do not fill containers to a height
where the contents, especially hot liquids,
could spill during braking, vehicle maneu-
vers, or in an accident.
When not in use, keep the cup holder
closed. An open cup holder may cause injury
to you or others when contacted during
braking, vehicle maneuvers, or in an acci-
dent.
Keep in mind that objects placed in the cup
holder may come loose during braking, vehi-
cle maneuvers, or in an accident and be
thrown around in the vehicle interior.
Objects thrown around in the vehicle interi-
or may cause an accident and/or serious
personal injury.
!No objects should be in the swiveling
cup holder when the swiveling cup
holder is slided upward. Otherwise the
swiveling cup holder or the objects
could be damaged.

Hood
Opening the hood
The hood lock release lever is located to
the left of the steering wheel under the
dashboard.
1 Hood lock release lever

Pull lever 1 downwards.
The hood is unlocked and handle 2
will extend out of the radiator grille.
2 Handle for opening the hood

Pull handle 2 to its stop out of
radiator grille.

Pull up on the hood (do not pull up on
the handle) and then release it.
The hood will be automatically held
open at shoulder height by gas-filled
struts.
Warning!
G
Do not pull the release lever while the vehi-
cle is in motion. Otherwise the hood could
be forced open by passing air flow.
!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
properly closed before driving. When closing
the hood, use extreme caution not to catch
hands or fingers.
The radiator fan may continue to run for ap-
proximately 30 seconds or even restart af-
ter the engine has been turned off. Stay
clear of fan blades.


292 OperationEngine compartment
Closing the hood
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 display 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
Mercedes-Benz Limited Warranty.
More information on this subject is
available at any Mercedes-Benz
Center.

5 Tire load rating
6 Tire speed rating General:
Depending on the design standards used,
the tire size molded into the sidewall may
have no letter or a letter preceding the tire
size designation.
No letter preceding the size designation
(as illustrated above): Passenger car tire
based on European design standards.
Letter “P” preceding the size designation:
Passenger car tire based on U.S. design
standards.
Letter “LT” preceding the size designation:
Light Truck tire based on U.S. design
standards.
Letter “T” preceding the size designation:
Temporary spare tires which are high
pressure compact spares designed for
temporary emergency use only. Tire width
The tire width
1 (
page 314) indicates
the nominal tire width in mm.
Aspect ratio
The aspect ratio 2 (page 314) is the
dimensional relationship between tire
section height and section width and is
expressed in percentage. The aspect ratio
is arrived at by dividing section height by
section width.
Tire code
The tire code 3 (
page 314) indicates
the tire construction type. The “R” stands
for radial tire type. Letter “D” means diag-
onal or bias ply construction; letter “B”
means belted-bias ply construction.
At the tire manufacturer’s option, any tire
with a speed capability above 149 mph
(240 km/h) can include a “ZR” in the size
designation (for example: 245/40 ZR 18).
For additional information, see “Tire speed
rating” (
page 316).

data on tires is specific to each vehicle
and may vary from data shown in above
