Air conditioning places an extra load
on the engine. Watch the engine
coolant temperature gauge (see page). If it moves near the red mark,
turn of f the A/C until the gauge
reads normally.
The heater uses engine coolant to
warm the air. If the engine is cold, it
will be several minutes bef ore you

Bef ore you begin driving your
vehicle, you should know what
gasoline to use and how to check the
levels of important f luids. You also
need to know how to properly store
luggage or packages. The

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 unleaded gasoline with a pump
octane number of 87 or higher. Use
of a lower octane gasoline can cause
a persistent, heavy metallic rapping
noise that can lead to engine damage.
We recommended using a quality
gasoline 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.Some gasoline today is blended with
oxygenates such as ethanol or
MTBE. Your vehicle is designed to
operate on oxygenated gasoline
containing up to 10% ethanol by
volume and up to 15% MTBE by
volume. Do not use gasoline
containing methanol.
If you notice any undesirable
operating symptoms, try another
service station or switch to another
brand of gasoline.
Premium f uel is recommended when
towing in certain conditions (see
page ).
For f urther important f uel-related
inf ormation f or your vehicle, or
inf ormation on gasoline that does not
contain MMT, visit Owner Link at
. In Canada, visit
f or additional
inf ormation on gasoline. 303

not try to ‘‘top of f ’’ the tank. This

Remove the f uel f ill cap slowly.
You may hear a hissing sound as

The fuel fill cap is attached to the

attachment on the fuel fill cap into
the slit on the f uel f ill door.
even though the tank is not f ull,
there may be a problem with your
vehicle’s fuel vapor recovery
system. The system helps keep
f uel vapor f rom going into the
atmosphere. Try f illing at another
pump. If this does not f ix the
problem, consult your dealer.

Screw the fuel fill cap back on
until it clicks at least once.
If you do not properly tighten the
cap, you will see a ‘‘CHECK FUEL
CAP’’ message on the inf ormation
display (see page ).If the system still detects a leak in
the 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
clicks at least once. The MIL should
go off after several days of normal
driving once the cap is tightened or
replaced. If the MIL does not go of f ,
have your vehicle inspected by a
dealer. For more inf ormation, see
page .
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. Turn the engine of f , and
conf irm the f uel f ill cap is installed. If
it is, loosen it, then retighten it until
it clicks at least once. The message
should go of f af ter several days of normal driving once you tighten or
replace the f uel f ill cap. To scroll to
another message, press the INFO
button. The ‘‘TIGHTEN FUEL CAP’’
message will appear each time you
restart the engine until the system
turns the message of f .
If you do not properly tighten the

If it is near or below the lower mark,

radiator reserve tank. Make sure it is

The f ollowing f actors can lower your
vehicle’s f uel economy:
Aggressive driving (hard
acceleration and braking)
Excessive idling, accelerating and
braking in stop-and-go traf f ic
Cold engine operation (engines
aremoreefficientwhenwarmedup)
Driving with a heavy load or the
air conditioner running
Improperly inf lated tires
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.
If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible.
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.
Idling
results in 0 miles per gallon (0 kms
per liter).
An underinf lated tire increases
‘‘rolling resistance,’’ which reduces
f uel economy.
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.

The A/C
puts an extra load on the engine
which makes it use more f uel. Use
