NOTICE:
Don’t drive in SECOND for more than 5 miles
(8 km), or at speeds over 55 mph (88 km/h), or
you can damage your transmission. Use
OVERDRIVE or
THIRD as much as possible.
Don’t shift into SECOND unless you are going
slower than
65 mph (105 km/h), or you can
damage’your engine.
FIRST (1): This position gives you even more power
(but lower fuel economy) than
SECOND (2). You can
use it
on very steep hills, or in deep snow or. mud. If the
selector lever is put
in FIRST (l), the transmission
won’t shift into
first gear until the vehicle is going
slowly enough.
NOTICE:
If your rear wheels can’t rotate, don’t try to
drive.
This might happen if you were stuck in
very deep sand
or mud or were up against a solid
object.’
You could damage your transmission.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the acceleratw
pedal.
This could overheat and damage the
transmission.
Use your brakes or shift into
BARK (P) to hold your vehicle in position
on.‘

Low Traction Light Engine Coolant Temperature Gage
LOW
TRAC
When your anti-lock system is adjusting brake pressure to
help avoid a braking skid, the
LOW TRAC light will
appear
on your instrument cluster. If you have the traction
control system,
this light will also come on when the
system is limiting wheel spin. Slippery road conditions
may
exist if this light comes on, so adjust your driving
accordingly. The light will stay on for a few seconds after
the
anti-lock system stops adjusting brake pressure or the
traction control system stops limiting wheel spin.
This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, your engine is too
hot! It means that your engine coolant has overheated. If
you have been operating your vehicle under normal
driving conditions, you should pull
off the road, stop
your vehicle and turn
off the engine as soon as possible.
In “Problems on the Road,”this manual shows what to
do. See “Engine Overheating” in the Index.
The LOW TRAC light also comes on briefly, as a bulb
check, when the engine is started.
If the light doesn’t
come
on then, have it fixed so it will be there to tell you
when the anti-lock brake system or traction control
system
is active.

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a
different turn signal flasher and extra wiring. The green
arrows on your instrument panel will flash whenever
you signal a turn or lane change. Properly hooked up,
the trailer lamps will also flash, telling other drivers
you’re about to turn, change lanes or stop.
When towing a trailer, the green arrows on your
instrument panel will flash for turns even if the bulbs on
the trailer are burned out. Thus, you may think drivers
behind you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade.
If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility of engine and transmission overheating.
If you are towing a trailer and you have an automatic
transmission with Overdrive, you may prefer
to driving
in THIRD
(D) instead of OVERDRIVE (or, as you need
to, a lower gear). Or, if you have
a manual transmission
with FIFTH (or SIXTH) gear and you are towing a
trailer, it’s better not to use FIFTH (or
SIXTH) gear.
Just drive in FOURTH (drive in FIFTH if you have a
six-speed manual transmission) or, as you need to, a
lower gear.

If No Steam Is Coming From Your Engine
If you
get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or so:
1.
2.
3.
If you have an air conditioner, turn it off.
Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
If you're in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (03)
or DRIVE (D) for automatic transmissions.
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about ten minutes.
If the warning doesn't come-back on, you
can drive
normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there's still no sign of steam, you can idle the engine
for
two or three minutes while you're parked, to see if
the warning stops. But then, if you still have the
warning,
turn oflthe engine and get everyone out of the
vehide
until it cools down.
You may decide not to lift the hood but to get 'service
help right away.

Engine damage from running your engine without coolant isn’t covered by your warranty.
If there seems to be no leak, check to see if the electric
engine fans are running.
If the engine is overheating,
both fans should be running.
If they aren’t, your vehicle
needs service.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
FWLL COLD, add a 50/50 mixture of clean
water (preferably distilled) and a proper antifreeze at the
coolant recovery tank. (See “Engine Coolant”
in the
Index for more information about the proper coolant
mix.)

When the coolant in the coolant recovery tank is at
WLL COLD, start your vehicle.
If the overheat warning continues, there’s one more
thing you can
try. You can add the proper coolant mix
directly to the radiator, but be sure the cooling system is 1
cool before you do it.
