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 kndh) with the
transnJission
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 kdh). 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 nlph (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 4H1,
but you should take your vehicle in for service to restore
norrnal operation.

Voltmeter Gage
When your engine is not
running. but the ignition is
on (in the RUN position).
this gage shows
your
battery’s state of charge in
DC volts.
VOLTS
When the engine is running, the gage shows the
condition
of the. charging system. Readings between the
low and high warning zones indicate the normal
operating range. Readings
in the
low warning mne may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since
the
charging system is not able to provide full power at
engine idle. As engine speeds are increased, this
condition should correct itself
as higher engine speeds
allow the charging system to create maximum power.
You can only drive for a short time with the reading in
either warning zone. If you must drive, turn off all
unnecessary accessories.
Readings
in either warning zone indicate a possible
problem
in the electrical system. Have the vehicle
serviced
as soon as possible.

dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did
you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making s111-e to fully install
the cap. The diagnostic system can cleter~nine
if the fuel cap
has been left off
or improperly installed. A loose or
missing fuel cap
will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed should turn
the light off,
Did you *just drive through a deep puddle of water’!
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Have you recently changed brands of fuel?
I1 so, be sure to fuel your vehicle with cpality fuel (see
“Fuel”
in the Index). Poor fuel quality will cause your
engine not to
r11n as e,fficiently as designed. You may
notice this
as stalling after start-up, stalling when you put
the vehicle
into gear, mistlring, hesitation on acceleration
or
stumbling on acceleration. (These conditions may go
away once the engine is warmed up.) This will be detected
by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use.
It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light. turn off.
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic
tools to fix any mechanical or electrical
problcnls that may have developed.

Canadian vehicles indicate pressure in kPa (kilopascals). Don't keep driving
if the oil pressure is
low. If'
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil
as soon as possible and have your
vehicle serviced.
