Downloaded from www.Manualslib.com manuals search engine 3. 4 LO: This setting also engages your front axle to give you extra
traction. You may never need
4 LO. It sends the maximum power to all
four wheels.
You might choose 4 LO if you were driving off-road in
sand, mud, deep snow and climbing or descending steep hills.
Indicator lights
in the switch show you which setting you are in. Both
indicator lights will come on briefly when
you turn on the ignition. If both
lights do
not come on, you should take your vehicle in for service. The 4 HI
position has a green indicator light and the 4 LO position has an amber
indicator light. When shifting, an indicator light will flash
until the shift is
completed then remain solidly lit.
Two-wheel drive, (2 WHEEL), does not have a switch position or an
indicator light. Your vehicle will be
in two wheel drive if neither indicator
light is
on.
To shift from two-wheel drive, (2 WHEEL) to 4 HI: Press and release the
4 HI switch. This can be done at any speed, and the front axle will lock
automatically.
To shift from 4 HI to two-wheel drive (2 WHEEL): Press and release the
4 HI switch. This can be done at any speed, and the front axle will unlock
automatically.
To shift from two-wheel drive (2 WHEEL) to 4 LO: The vehicle must be
stopped or moving less than
3 mph (4.8 km/h) with the transmission in “N’
(Neutral) or the clutch pedal depressed. The preferred method for shifting
into
4 LO is to have your vehicle slowly moving one-to-two mph (1.6 to
3.2 kdh). Press and release the 4 LO switch. You must wait for the amber
4 LO indicator light to stop flashing and go solid amber before shifting your
transmission
into gear or releasing the clutch pedal.
If the
4 LO switch is pressed when your vehicle is in gear and/or moving,
the amber
4 LO indicator light will flash for 30 seconds and not complete
the shift unless your vehicle is below
3 mph (4.8 kdh) and the transmission
is in
“N” (Neutral) or the clutch pedal depressed.
On automatic transmission equipped vehicles: If your transfer case does not
shift into
4 LO, your transmission indicator switch may require adjustment.
With your transmission in
“N” (Neutral), press and release the 4 LO
switch. While the amber 4 LO indicator light is flashing, shift your
transmission into
P (Park).

(SERVICE ENGINE SOON)
Standard Cluster
A computer monitors operation of your fuel, ignition and emission control
systems. This light should come on when the ignition is
on, but the engine is
not running, as a check to show you it is working. If it does not come on at
all, have it fixed right away.
If it stays on, or it comes on while you are
driving, the computer is indicating that you have a problem. You should
take your vehicle in
for service soon.
NOTICE:
If you keep driving your vehicle with this light on, after a \
while
the emission controls won’t work as well, your fuel economy \
won’t be as good and your engine may not run
as smoothly. This
could lead to costly repairs not covered by your warranty.

‘To help prevent damage to your exhaust system, do not continue to drive
your vehicle
if you notice:
Engine misfiring
Loss of performance
0 Other unusual operating conditions
Have your engine and exhaust system serviced regularly.
Three- Way Catalytic Converter
Your vehicle’s three-way catalytic converter is designed to reduce the
pollutants
in your vehicle’s exhaust. Use only unleaded fuel in your vehicle.
If you use leaded fuel, you could damage your three-way catalytic converter
and other engine components.
Engine Control Module System
This system has an oxygen (02) sensor that helps keep your engine’s
air-fuel mixture at a proper level. Use only unleaded fuel
in your vehicle. If
you use leaded fuel, you could damage your oxygen (02) sensor and affect
your vehicle’s emissions.
Malfunction Indicator Lamp (SERVICE ENGINE SOON )
This light on your instrument panel lets you know when your emission
system needs service. The light
will come on briefly when you start your
engine to let you know that the system is working.
If it does not come on
when you start your engine, or
if it comes on and stays on while you’re
driving, your system may need service. Your vehicle should still be
driveable, but you should have your system serviced right away.

Downloaded from www.Manualslib.com manuals search engine When lt’s Time for New Tires
One way to tell when
it’s time for new tires
is to check the
treadwear indicators,
which will appear
when your tires have
only
2/32 inch
(1.6 mm) or less of
tread remaining.
You need a new tire if
0 You can see the indicators at three or more places around the tire.
You can see cord or fabric showing through the tire’s rubber.
The tread or sidewall is cracked, cut or snagged deep enough to show
cord or fabric.
0 The tire has a bump, bulge or split.
The tire has a puncture, cut, or other damage that can’t be repaired well
because
of the size or location of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at the
CertificatiodTire label.
The tires installed
on your vehicle when it was new had a Tire Performance
Criteria Specification (TPC Spec) number
on each tire’s sidewall. When you
get new tires, get
ones with that same TPC Spec number. That way, your
vehicle will continue to have tires that are designed to give proper
endurance, handling, speed rating, traction, ride and other things during
normal service
on your vehicle. If your tires have an all-season tread
design, the
TPC number will be followed by a “MS” (for mud and snow).
