Your vehicle’s on board diagnostic
system will detect a loose or missing
f uel f ill cap as an evaporative system
leak. The f irst time a leak is detected
a ‘‘TIGHTEN FUEL CAP’’ message
appears on the multi-inf ormation
display. If the system still detects a leak in
your vehicle’s evaporative emissions
system, the malf unction indicator
lamp (MIL) comes on. If the f uel f ill
cap was not already tightened, turn
the engine of f , and check or
retighten the f uel f ill cap until it

Remove the dipstick again, and
check the level. It should be
between the upper and lower
marks.
If it is near or below the lower mark,
see on page . To access the radiator reserve tank,
remove the right-side engine
compartment cover (see page ).
See page f or the engine coolant
location.
Refer to
on page f or inf ormation
about checking other items on your

Look at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, see on page f or
inf ormation on adding the proper
coolant.

The f ollowing f actors can lower your
vehicle’s f uel economy:
A properly maintained vehicle
maximizes f uel economy. Poor
maintenance can signif icantly reduce
f uel economy. Always maintain your
vehicle according to the maintenance messages displayed on the
inf ormation display (see
on page ).
For example: Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption.
Aerodynamic drag has a big ef f ect
on f uel economy at speeds above
45 mph (75 km/h). Reduce your
speed and you reduce the drag.
Trailers, car top carriers, roof
racks and bike racks are also big
contributors to increased drag.
If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible.
Idling
results in 0 miles per gallon (0 kms
per liter).
It puts a heavier
load on the engine, increasing f uel
consumption.
In
particular, a build-up of snow or
mud on your vehicle’s underside
adds weight and rolling resistance.
Frequent cleaning helps your f uel
economy. An underinf lated tire increases
‘‘rolling resistance,’’ which reduces
f uel economy. 505

These indicators between the
tachometer and speedometer show
which position the shif t lever is in. Using a paddle shift mode, the
gear position indicator shows
you the selected gear number
(see page
).
The ‘‘D’’ indicator comes on f or a
f ew seconds when you turn the
ignition switch to the ON (II)
position. If it f lashes while driving (in
any shif t position), it indicates a
possible problem in the transmission. Models equipped with the
keyless access system have an
engine start/stop button instead
of an ignition switch. ON Mode
is the equivalent of ON (II). For
more inf ormation, see pages
and .
If the malf unction indicator lamp
comes on along with the ‘‘D’’
indicator, there is a problem with the
automatic transmission control
system. Avoid rapid acceleration and
have the transmission checked by
your dealer as soon as possible.
When the ‘‘D’’ indicator warns of a
possible problem with the
transmission, you will see a ‘‘CHECK
