WARNING
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
As a result, you will not be able to see
information about your driving
conditions, such as speed, outside
temperature, or warning/indicator lamps.
Driving characteristics may be impaired.
If you must continue to drive, please do so
with added caution. Visit an authorized
smart center as soon as possible.
Multifunction display illumination The multifunction display illumination
comes on when the starter switch is in
position
1.
It goes out after approximately
30 seconds when the starter switch is in
position 0.
For adjusting the multifunction display
illumination, see “Adjusting instrument
cluster illumination” ( Y page 92).

Fuel level display
Example illustration (U.S. vehicles)
The
fuel level display shows the tank’s fuel
level with the aid of eight segments. The
number of dark segments indicates the fuel
level in the tank. If all eight segments are
dark, the tank is full.
You are driving on reserve fuel if there are
no more than 1.0 US gal (3.78 l) of fuel in the
tank.
If this occurs,
R the fuel pump symbol in the fuel level
display flashes
R the reserve fuel indicator shows the fuel
level in the tank in 0.1 US gal (0.5 l)
increments
For selecting the reserve fuel indicator to
be displayed in the status indicator, see
“Reserve fuel indicator” (Y page 91). Selecting display for status indicator
You can select the information to be
displayed in the status indicator:
R Trip odometer display ( Y page 90)
R Maintenance service interval display

instead of miles.
The maintenance service interval display
will notify you approximately one month
before the next maintenance service is
due.
The following information will be
displayed after starting the engine:
R Days or distance to next maintenance
service
This information will be displayed
instead of the main odometer display.
The
main odometer display will reappear
after approximately ten seconds
(Y page 87).
R Type of service that is due
This information will be displayed in
the status indicator.
X Start the engine. X
Selecting maintenance service interval
display: Press button : on the
instrument cluster repeatedly until the
maintenance service interval display
appears in the status indicator.
Depending on the type of maintenance
service that is due, symbol ¬ or } is
displayed.
X Clearing maintenance service interval

Check
Tire Pressure The tire inflation pressure in at least one tire is
significantly below the reference value.
X
Carefully bring the vehicle to a halt, avoiding abrupt
steering and braking maneuvers.
X Check and adjust tire inflation pressure as required
(Y page 126).
X If necessary, change the wheel ( Y page 194).G
WARNING
Each tire should be checked monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the Tire and Loading Information placard. If
your vehicle has tires of a different size than the size indicated on the Tire and Loading
Information placard, you should determine the proper tire inflation pressure for those
tires.
As
an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires
is significantly underinflated.
Accordingly, when the low tire pressure telltale illuminates, you should stop and check your
tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly
underinflated tire causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability. Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even
if underinflation has not reached the level to trigger illumination of the TPMS low tire
pressure telltale.

Engine oils are specifically tested for
their suitability in our engines and
durability for our service intervals.
Therefore, only use engine oils and oil
filters required for vehicles with the
Maintenance System. For a listing of
approved engine oils and oil filters
contact an authorized smart center.
! Using engine oils and oil filters of
specification
other than those expressly
required for the Maintenance System, or
changing of oil and oil filter at change
intervals longer than those called for by
the Maintenance System will result in
engine or emission control system
damage not covered by the smart Limited
Warranty. Please follow Maintenance System
recommendations for scheduled oil
changes. Failure to do so will result in
engine or emission control system
damage
not covered by the smart Limited
Warranty.
Viscosity grades for engine oils Using the chart below, select oil viscosity
according to the lowest air temperature
expected before the next oil change.
27 Use a windshield washer concentrate labeled for summer and water for temperatures above freezing
point
or a windshield washer concentrate labeled for winter and water for temperatures below freezing
point. 220
