Help assure your vehicle’s f uture
reliability and perf ormance by paying
extra attention to how you drive
during the f irst 600 miles (1,000 km).
During this period:Avoid full-throttle starts and rapid
acceleration.
Do not change the oil until the
scheduled maintenance time.
Avoidhardbrakingforthefirst
200 miles (300 km).
Do not tow a trailer.
You should also f ollow these
recommendations with an
overhauled or exchanged engine, or
when the brakes are replaced. Your vehicle is designed to operate
on premium unleaded gasoline with a
pump octane number of 91 or higher.
Useof aloweroctanegasolinecan
cause occasional metallic knocking
noises in the engine and will result in
decreased engine perf ormance. Use
of a gasoline with a pump octane
number less than 87 can lead to
engine damage.
Your vehicle is designed to operate
on premium unleaded gasoline with a
pump octane of 91 or higher. If this
octane grade is unavailable, regular
unleaded gasoline with a pump
octane of 87 or higher may be used
temporarily. The use of regular
unleaded gasoline can cause metallic
knocking noises in the engine and
will result in decreased engine
perf ormance. The long-term use of
regular-grade gasoline can lead toengine damage.
We recommend using quality
gasolines containing detergent
additives that help prevent fuel
system and engine deposits.
In addition, in order to maintain good
perf ormance, f uel economy, and
emissions control, we strongly
recommend, in areas where it is
available, the use of gasoline that
does NOT contain manganese-based
f uel additives such as MMT.
Use of gasoline with these additives
may adversely af f ect perf ormance,
and cause the malfunction indicator
lamp on your instrument panel to
come on. If this happens, contact
your authorized dealer f or service.4-cylinder models

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, seeon page f or

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 multi-
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).
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. It puts a heavier
load on the engine, increasing f uel
consumption. An underinf lated tire increases
‘‘rolling resistance,’’ which reduces
f uel economy.
