Controls in detail
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!

driving. Activating the memory function
while driving could cause the driver to lose
control of the vehicle.

120 Controls in detailInstrument clusterCoolant temperature gauge
The coolant temperature gauge is on the
left side in the instrument cluster
(page 25).During severe operating conditions, e.g.
stop-and-go traffic, the coolant tempera-
ture may rise close to 248°F (120°C).
The engine should not be operated with
the coolant temperature above 248°F
(120°C). Doing so may cause serious
engine damage which is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G


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 hood. Stay away from
the engine if you see or hear steam com-
ing from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.

Controls in detail
Instrument cluster
Trip odometer
Make sure you are viewing the trip
odometer and main odometer in the
multifunction display (
page 123).

If it is not displayed, press button
è
or ÿ on the multifunction steering
wheel until the trip odometer appears
(page 124).

Press and hold the reset button in the
instrument cluster (
page 119) until
the trip odometer is reset.
Tachometer
The red marking on the tachometer
(page 24) denotes excessive engine
speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
Outside temperature indicator
!Avoid driving at excessive engine
speeds, as it may result in serious
engine damage that is not covered by
the Mercedes-Benz Limited Warranty.
Warning!
G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
