µIf the driver’s
window senses any obstacle while it
is closing automatically, it will
reverse direction, and then stop. To
close the window, remove the
obstacle, then use the window switch
again.
Auto reverse stops sensing when the
window is almost closed. You should
always check that all passengers and
objects are away from the window
bef ore closing it. Your vehicle has a power back
window.
This indicator comes on when you
turn the ignition switch from the ON
(II) position to the ACCESSORY (I)
or LOCK (0) position without closing
the back window. With the ignition
switch in the ACCESSORY (I)
position, the indicator goes off after
about 30 seconds. With the ignition
switch in the LOCK (0) position, the
indicator goes of f af ter about 3
minutes.
If the driver’s window f use is
removed, the AUTO f unction may be
disabled. The power window system
needs to be reset af ter reinstalling
the fuse.
Start the engine. Push down and
hold the driver’s window switch
until the window is f ully open.
Pull and hold the driver’s window
switch to close the window
completely, then hold the switch

Wait a f ew minutes af ter turning the
engine of f bef ore you check the oil.Remove the dipstick (orange loop).
Wipe of f the dipstick with a clean
cloth or paper towel.
Insert the dipstick all the way back
into its hole. 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 . 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:
Aggressive driving (hard
acceleration and braking)
Excessive idling, accelerating and
braking in stop-and-go traf f ic
Cold engine operation (engines
aremoreefficientwhenwarmed
up)
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: An under-inf 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.
Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption. Aerodynamic drag has a big ef f ect
on f uel mileage 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.
Combine several short trips into
one. A warmed-up engine is more
f uel ef f icient than a cold one. The A/C
puts an extra load on the engine
which makes it use more f uel. Use
the f resh-air ventilation when
possible.

Youshoulddothefollowingchecks
and adjustments bef ore you drive
your vehicle.Make sure all windows, mirrors,
and outside lights are clean and
unobstructed. Remove f rost, snow,
or ice.
Check that the hood is f ully closed.
Check that the tailgate is f ully
closed when it is not used as an
extended pickup bed.
Visually check the tires. If a tire
looks low, use a gauge to check its
pressure.
Check that any items you may be
carrying are stored properly or
f astened down securely. Check the adjustment of the
inside and outside mirrors (see
page ).
Check the steering wheel
adjustment (see page ).
Make sure the doors and In-Bed
Trunk are securely closed and
locked.
Fasten your seat belt. Check that
your passengers have f astened
their seat belts (see page ).
When you start the engine, check
the gauges and indicators in the
instrument panel (see page ).
Check the seat adjustment (see

Insert a key into the shift lock
release slot.
Push down on the key while you
pull the shif t lever towards you,
and move it out of Park to neutral.Remove the key from the shift
lock release slot, then reinstall the
cover. Make sure the notch on the
cover is on the instrument panel
side. Press the brake pedal, and
restart the engine.
If you need to use the shif t lock
release, it means your vehicle is
developing a problem. Have it
checked by your dealer. Your vehicle is equipped with a
variable torque management
4-wheel-drive system (VTM-4) that
distributes engine torque to the
appropriate drive axle depending on
the available traction conditions. The
system is completely automatic,
always active, and does not require
any driver interaction.

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.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.
Under-inf 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, the sensor in that
tire immediately sends a signal that
causes the low tire pressure
indicator and the appropriate tire on
thetirepressuremonitortocomeon.

Your vehicle is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. The emergency
brake assist system increases the
stopping f orce when you depress the
brake pedal hard in an emergency
situation. 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, and reduces their ef f ectiveness
and reduces brake pad life. 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.
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 and alert 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.
