Drive moderately. Rapid
acceleration, abrupt cornering,
and hard braking use more fuel.
Always drive in the highest gear
possible.
Try to maintain a constant speed.
Everytimeyouslowdownand

messages. See (page ).
an underinf lated tire
causes more ‘‘rolling resistance,’’
which uses more f uel.
The build-up of snow or mud on
your vehicle’s underside adds
weight and rolling resistance.
Frequent cleaning helps your f uel
mileage and reduces the chance of
corrosion. 381

Check the adjustment of the
inside and outside mirrors (see
page ).
Check the steering wheel
ad justment (see page ).
Make sure the doors and tailgate
are securely closed and locked.
Fasten your seat belt. Check that
your passengers have fastened
their seat belts (see page ).
Wh en you start the engine, check
the gauges and indicato rs in the
instrument panel, and the
messages on the multi-info rmation
display (see page , 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 for about 6 to 9
seconds until the engine starts.
If you hold the ignition switch in
the START (III) position for more
than 7 seconds, the starter motor,
depending on the outside
temperature, runs for about 10 to
25 seconds until the engine starts.
If the engine does not start, wait at
least 10 seconds before trying
again.
Make sure the shift lever is in
Park. Press on the brake pedal.
In
cold weather, turn off 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 feature keeps the
engine’s starter motor running until
the engine starts. Follow these

until the engine starts. The
ignitionswitchcanbeheldinthat
position up to 15 seconds.
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.

The engine is harder to start in cold
weather. Also, the thinner air f ound at
altitudes above 8,000 f eet (2,400
meters) adds to this problem.

The ‘‘D’’ indicator comes on for a
few seconds when you turn the
ignition switch to the ON (II)
position. If it flashes while driving (in
any shift position), it indicates a
possible problem in the transmission.
If the malfunction indicator lamp
comes on along with the ‘‘D’’
indicato r, there is a problem with the
automatic transmission control
system. Avoid rapid acceleration, and
have the transmission checked by
your dealer as soon as possible.
When the ‘‘D’’ indicator warns of a
possible problem with the
transmission, you will see a ‘‘CHECK
TRANSMISSION’’ message on the
multi-inf ormation display (see page ).
These indicators on the instrument
panel show which position the shif t
lever is in. In the Sequential
SportShif t Mode, the ‘‘M’’ indicator
next to the ‘‘D’’ indicator comes on,
and the illuminated number under
the charging system indicator shows
you the gear you have selected. To shif t f rom Park to any position,
press firmly on the brake pedal and
pressthereleasebuttononthefront
of the shif t lever, then pull the lever.

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 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.
To see the inf lation pressures of all
f our tires, press the SEL/RESET
button. The display changes as
shown above.
Each tire pressure is shown in PSI
(U.S. models) or in kPa (Canadian
models).

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. 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 brake pedal
applies the brakes slightly. This
builds up heat, and reduces brake
ef f ectiveness and 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.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.
All f our brakes have audible brake
wear indicators.
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.
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.

Park the vehicle on level ground.
Measure and record the distance
from the ground to the bottom of
the trailer hitch.
Connect the fully loaded trailer to
the hitch.
Measure again from the ground to
the same spot on the bottom of the
hitch.
Subtract the second measurement
from the first measurement, then
refer to the following table.
Add
the weight of your trailer (as
quoted by the manufacturer) with
everything in or on the trailer. Then
check the tables on page to
make sure you do not exceed the
limit f or your conditions. To help ensure a saf e drive to a scale,
or if you cannot get to a public scale,
we recommend that you estimate
your total trailer weight and tongue
load as described next. Thebestwaytoconfirmthatall
loads are within limits is to check
them at a public scale. For public
scales in your area, check your local
phone book, or contact your trailer
dealer or rental agency for
assistance.
Estimated
tongue load is:
150 lbs (68 kg)
250 lbs (114 kg)

If the autom atic transmission fluid
temperature increases and exceeds
the speci fied limit, the A/T
temperature indicator comes on (see
page ). You will also see a ‘‘A/T
TEMP HIGH’’ message on the multi-
information display.
Make turnsmoreslowlyandwider
than normal. The trailer tracks a
smaller arc than your vehicle, and it
canhitorrunoversomethingthe
vehicle misses.
Allow more time and distance for
braking. Do not brake or turn
suddenly as this could cause the
trailer to jackknife or turn over.
When
driving uphill and downhill,
use the Sequential SportShift mode
to provide the proper engine power
and engine braking on each gear.
Select fourth, third, second, or first
gear; dep ending on the vehicle
speeds and road condition. Do not
use fifth gear. The recommended
speed range for each gear position is
showninthetable.

Drive
slower than normal in all

speed limits for vehicles with trailers.
Use D position when towing a trailer
on level roads. D is the proper shif t
lever position to use when towing a
trailer in hilly terrain. (See ‘‘ ’’onthenextpagefor
additional gear information.)
When towing a f ixed-sided trailer (e.
g., camper), do not exceed 55 mph
(88 km/h). At higher speeds, the
trailer may sway or affect vehicle
handling. 68
