Downloaded from www.Manualslib.com manuals search engine Shifting from 4LO to 4HI or 2HI
To shift from 4LO to 4HI or 2H1, your vehicle must be
stopped or moving less than 3 mph (4.8 kmh) with the
transmission in NEUTRAL (N) or the clutch pedal
engaged. The preferred method for shifting out
of
4LO is to have your vehicle moving 1 to 2 mph (1.6 to
3.2 km/h). Press and release the 4HI switch. You must
wait for the
4HI indicator light to stop flashing and
remain illuminated before shifting your transmission
into gear or releasing
the clutch pedal.
If the 4HI switch is pressed when your vehicle is in gear
and/or moving, the
4HI indicator light will flash for
30 seconds but not complete the shift unless the
vehicle is moving slower than
3 mph (4.8 km/h) and
the transmission
is in NEUTRAL (N) or the clutch
pedal engaged.
On automatic transmission equipped vehicles, if your
transfer case does not shift into
4H1, your transmission
indicator switch may require adjustment. With your
transmission in NEUTRAL
(N), press and release the
4HI switch. While the 4HI indicator light is flashing,
shift your transmission into PARK
(P). Wait until the
4HI indicator light remains illuminated before shifting
your transmission into gear. This will get
you into 4HI.

Running (Automatic Transmission
Models Only)
I A CAUTION:
It can be dangerous to leave your vehicle with the
engine running. Your vehicle could move suddenly
if the shift lever is not fully in PARK (P) with the
parking brake firmly
set. If you have four-wheel
drive with
a manual transfer case shift lever and
your transfer case is in NEUTRAL (N), your
vehicle will
be free to roll, even if your shift lever
is in PARK (P). So be sure the transfer case is in a
drive gear -- not in NEUTRAL (N). And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire. You or others could
be injured. Don't leave your vehicle with the
engine running unless you have to.
If you have to leave your vehicle with the engine
running, be sure your vehicle is
in PARK (P) and your parking brake
is firmly set before
you leave it. After
you've moved the shift lever into the
PARK (P)
position, hold the regular brake pedal down. Then, see
if you can move the shift lever away from PARK (P)
without first pulling it toward you (or pressing the
button
on a console shift lever). If you can, it means that
the shift lever wasn't
fully locked into PARK (P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you don't shift your
transmission
into PARK (PI properly, the weight of the
vehicle may
put too much force on the parlung pawl in the
tr'msmission.
You may find it difficult to pull the shift
Icver out of PARK (P). This is called "torque lock." To
prevent torque lock, set the parking brake and then shift
into
PARK (P) properly before you leave the driver's seat.
To find out how, see "Shifting Into PARK (P)" in
the Index.
When you are ready to drive, move the shift lever out
of
PARK (P) before you release the parking brake.
If torque lock does occur. you may need to have another
vehicle push yours a little uphill
to take some of the
pressure from the parking pawl
in the transmission, so
you can pull the shift lever out of PARK (P).

(Automatic Transmission)
Your vehicle has a brake-transmission shift interlock.
You have
to fully apply your regular brake before you
can shift from PARK (P) when the ignition is in the
RUN position. See “Automatic Transmission Operation”
in the Index.
If
you cannot shift out of PARK (P), ease pressure on
the shift lever
-- push the shift lever all the way into
PARK (P) as you maintain brake application. Then
move the shift lever into the gear
you want (you must
press the shift lever button if
you have the console
shift lever).
If you ever hold the brake pedal down but still can’t
shift out
of PARK (P), try this:
1. Turn the key to OFF.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear
you want.
5. Have the vehicle fixed as soon as you can.
Parking Your Vehicle (Manual
Transmission Models Only)
Before you get out of your vehicle, turn off your engine,
put your manual transmission in
REVERSE (R) and
firmly apply the parking brake.
If you have four-wheel drive with a manual transfer case
shift lever,
be sure your transfer case is in a drive gear.
Your vehicle could roll
if it isn’t.

to, here are some things to know.
A CAUTION:
Idling the engine with the air system control
off could allow dangerous exhaust into
your vehicle (see the earlier Caution under
“Engine Exhaust”).
Also, idling in
a closed-in place can let deadly
carbon monoxide
(CO) into your vehicle even if
the fan switch is at the highest setting. One place
this can happen is
a garage. Exhaust 9- with
CO -- can come in easily. NEVER park in a
garage
with the engine running.
Another closed-in place can be a blizzard.

Downloaded from www.Manualslib.com manuals search engine Speedometer and Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has been
driven,
in either miles (used in the United States) or
kilometers (used
in Canada).
Your odometer is tamper resistant. It will show silver lines
between the numbers
if someone tries to turn it back.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to the
mileage total of
the old odometer, then it must be. But if
it can’t, then it’s set at zero, and a label must be put on
the driver’s door to show the old mileage reading when
the new odometer was installed.
Trip Odometer
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
To set the trip odometer to zero, press the button near
the readout
.
Tachometer (If Equipped)
The tachometer displays the engine speed in revolutions
per minute (rpm). Each
tachometer has
a different limit depending on the
powertrain
in your vehicle. The tachometer has three
areas: normal operating range, red warning range and
red danger range.
The normal operating range shows your engine speed
during normal driving conditions.
For example, when
the needle points to
2, it means the engine is running at
2,000 revolutions per minute (rpm). The tachometer
needle
will vary all the time that the engine is running.
The shaded red warning range teIls you
that your engine
speed is reaching
its upper limits. Don’t drive very long
with the tachometer in the red warning range. If you
have
a manual transmission, shift to a higher gear as
soon as possible. If you have an automatic transmission,
lift your foot off of the accelerator pedal.
The solid red danger range tells
you that your engine speed
is at its upper limits. Your should immediately shift to a
higher gear, or lift your foot off of the accelerator pedal.
I NOTICE:
Do not operate the engine with the tachometer in
the red range,
or engine damage will occur.

There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
your rig
will be legal, not only where you live but
also where you’ll be driving.
A good source for this
information can be state or provincial police.
Consider using a sway control if your trailer
will
weigh 2,000 lbs. (900 kg) or less. You should always
use
a sway control if your trailer will weigh more
than
2,000 lbs. (900 kg). You can ask a hitch dealer
about sway controls.
Don’t tow a trailer at all during the first
500 miles
(800 km) your new vehicle is driven. Your engine,
axle
or other parts could be damaged.
Then, during the first
500 miles (800 km) that you
tow
a trailer, don‘t drive over 50 mph (80 kmh) and
don’t make starts
at full throttle. This helps your
engine and other parts
of your vehicle wear in at the
heavier loads.
If you have an automatic transmission, you can use
DRIVE
(D) (or. as you need to, a lower gear) when
towing
a trailer. Operating your vehicle in
DRIVE (D) when towing a trailer will minimize heat
buildup and extend the life
of your transmission. If
you have a manual transmission and you are towing
a trailer, it’s better not to use FIFTH (5) gear. Just
drive
in FOURTH (4) gear (or, as you need to, a
lower gear).
Three important considerations have
to do with weight:
0 the weight of the trailer,
the weight of the trailer tongue
and the weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It depends
on how you plan to use your rig. For
example, speed. altitude, road grades. outside
temperature and how much your vehicle
is used to pull a
trailer are all important. And, it can also depend on any
special equipment that
you have on your vehicle.
The following chart shows how much your trailer can
weigh, based upon your vehicle model and options.

panel
will flash for turns even if the bulbs on the trailer
are burned out. Thus, you may
