Wait a f ew minutes af ter turning the
engine of f bef ore you check the oil.
Put your f ingers under the f ront
edge of the hood near the center.
Slide your hand to the lef t until
you f eel the hood latch handle.
Push this handle up to release it.
Lif t up the hood.
If the hood latch handle moves
stif f ly, or if you can open the hood
without lifting the handle, the
mechanism should be cleaned and
lubricated. Pull the support rod out of its clip
by holding the grip, and insert the
end into the designated hole in thehood.
To close the hood, lif t it up slightly
to remove the support rod f rom
the hole. Put the support rod back
into its holding clip. Lower the
hood to about a f oot (30 cm) above
the fender, then let it drop. Make
sure it is securely latched.
Remove the dipstick (orange
handle).
Insert it all the way back in its tube.
Wipe of f the dipstick with a clean
cloth or paper towel.

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).
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.

If you exceed the maximum speed
f or the gear you are in, the engine
speed will enter into the tachometer’s
red zone. If this occurs, you may f eel
the engine cut in and out. This is
caused by a limiter in the engine’s
computer controls. The engine will
run normally when you reduce the
rpm below the red zone.
Bef ore downshif ting, make sure the
engine will not go into the
tachometer’s red zone.
Your vehicle has a rev limit indicator
to show you when the engine speed
is near the tachometer’s red zone
(see page ).If you are still unable to shif t to
reverse, apply the parking brake,
and turn the ignition key to the
ACCESSORY (I) or LOCK (0)
position.
With the clutch pedal still pressed,
start the engine.
Press the clutch pedal, and shif t to
reverse.
If you need to use this procedure to
shif t to reverse, your vehicle may be
developing a problem. Have the
vehicle checked by your dealer.
The manual transmission has a
lockout so you cannot accidentally
shif t f rom any f orward gear to
reverse while the vehicle is moving
at a certain speed. If you cannot shif t
to reverse when the vehicle is
stopped, do the f ollowing:
With the clutch pedal pressed,
move the shift lever to the first/
second gear side of the neutral
gate, then shif t to reverse.

Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently until they do. Be extra
cautious in your driving.
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal f or
the brakes to occasionally squeal or
squeak when you apply them.
Your vehicle is equipped with f ront
disc brakes. The brakes on the rear
wheels may be disc or drum,
depending on the model. A power
assist helps reduce the ef f ort needed
on the brake pedal. The anti-lock
brake system (ABS) helps you retain
steering control when braking very
hard.
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, reduces their ef f ectiveness and
reduces brake pad lif e. In addition,
f uel economy can be reduced. It also
keeps your brake lights on all the
time, conf using drivers behind you.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by taking your f oot of f the
accelerator and downshif ting to a
lower gear. Braking System Design

When the low tire pressure indicator
is on, one or more of your tires is
signif icantly underinf lated. You
should stop and check your tires as
soon as possible, and inf late them to
the proper pressure as indicated on
the vehicle’s tire inf ormation placard.
If you think you can saf ely drive a
short distance to a service station,
proceed slowly, and inf late the tire to
the recommended pressure shown
on the driver’s doorjamb.
If the tire is f lat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire (see page ).
If you cannot make the low tire
pressure indicator go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible.Driving on a signif icantly under
inf lated tire causes the tire to
overheat and can lead to tire failure.
Underinf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure indicator may
come on unexpectedly.
Each tire has its own pressure
sensor (not including the spare tire).
If the air pressure of a tire becomes
signif icantly low while driving, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure indicator to come on.
Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.
