Wait a f ew minutes af ter turning the
engine of f bef ore you check the oil.Remove the dipstick (orange loop). 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.
Refer to
on page f or inf ormation
about checking other items on your
vehicle.
Wipe of f the dipstick with a clean
cloth or paper towel.
Insert the dipstick all the way back
into its hole.

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: 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.

Check the adjustment of the
inside and outside mirrors (see
page ).
Check the steering wheel
adjustment (see page ).
Make sure the doors and tailgate
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, and the
messages on the multi-inf ormation
display (see pages , and). Without touching the accelerator
pedal, turn the ignition switch to
the START (III) position, then
release the ignition switch. You do
not need to hold the ignition
switch in the START (III) position
to start the engine. Depending on
the outside temperature, the starter motor runs f or about 6 to 9
seconds until the engine starts.
If you hold the ignition switch in
the START (III) position f or more
than 7 seconds, the starter motor,
depending on the outside
temperature, runs f or about 10 to
25 seconds until the engine starts.
If the engine does not start, wait at
least 10 seconds bef ore trying
again.
Make sure the shif t lever is in
Park. Press on the brake pedal. In cold weather, turn of f all
electrical accessories to reduce
the drain on the battery. Apply the parking brake.
Your vehicle’s starting system has an
auto control mode. When you turn
the ignition switch to the START
(III) position, this f eature keeps the
engine’s starter motor running until
the engine starts. Follow these

Even though you may be able to
start the engine manually without
the auto control mode of the starting
system, have your dealer inspect
your vehicle.
If there is a problem with the
starting system, you will see a
‘‘CHECK STARTING SYSTEM’’
message on the multi-inf ormation
display when the ignition switch is
turned to the ON (II) position. You
will also see this message when the
auto control mode of the starting
system has a problem.
If the engine does not start within
15 seconds, or starts but stalls
right away, repeat step 4 with the
accelerator pedal pressed halfway
down. If the engine starts, release
pressure on the accelerator pedal
so the engine does not race.
If the engine fails to start, press
the accelerator pedal all the way
down, and hold it there while
starting to clear flooding. If the
engine still does not start, return
to step 5.

weather. Also, the thinner air f ound at
altitudes above 8,000 f eet (2,400

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.
Each tire has its own pressure
sensor. 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/TPMS indicator in the
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
inf ormation display along with a
‘‘CHECK TIRE PRESSURE’’
message.If you think you can saf ely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure.
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 ).
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/TPMS
indicator may come on unexpectedly.
When the low tire pressure/TPMS
indicator is on, one or more of your
tires is signif icantly underinf lated.
Youshouldstopandcheckyourtires
as soon as possible, and inflate them
to the proper pressure as indicated
on the vehicle’s tire inf ormation
placard.
It is possible that the pressures
shown on the multi-inf ormation
display and the pressures you
manually measure are slightly
dif f erent.
If the dif f erence is signif icant or you
cannot make the low tire pressure/
TPMS indicator and message on the
multi-inf ormation display go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible.

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 in your driving.
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.As required by the FCC:
This device complies with Part 15 of theFCC rules. Operation is subject to thef ollowing two conditions: (1) This devicemay not cause harmf ul interf erence, and(2) this device must accept anyinterf erence received, includinginterf erence that may cause undesiredoperation.Changes or modif ications not expresslyapproved by the party responsible f orcompliance could void the user’sauthority to operate the equipment.This device complies with IndustryCanada Standard RSS-210.Operation is subject to the f ollowing twoconditions: (1) this device may not causeinterf erence, and (2) this device mustaccept any interf erence that may causeundesired operation of the device.
