Features and Controls
L (Low Gear)
This position gives you even more power
(but lower fuel economy) than
“2.” You
can use it on very steep hills, or
in deep
snow
or mud. If the selector lever is put il
“L,” the transmission won’t shift into low
gear until the vehicle is going slowly
enough.
n
NOTICE:
Don’t shift into “L,” (Low) at speeds
above 40 mph
(65 km/h) with the
transfer case
in “4L,” or you can
damage your transmission.
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 accelerator pedal. This could
overheat and damage the
transmission. Use your brakes to hold
your vehicle
in position on a hill.

is is your shift pattern. Here’s how to
erate your transmission:
1 (First Gear) - Press the clutch
pedal and shift into
“1.” Then, slowly
let up on
the clutch pedal as you press
the accelerator pedal.
You can shift into
“I” when you’re
going less than
20 mph (32 km/h). If
you’ve come to a complete stop and
it’s hard to shift into
“1,” put the shift
lever
in “Neutral” and let up on the
clutch. Press the clutch pedal back
down. Then shift into
“ 1 .”

you let up on the accelerator
pedal and shift into
“2.” Then, slowly
let up on the clutch pedal as you press
the accelerator pedal.
3,4 and 5 (Third, Fourth and Fifth
Gears)
- Shift into “3,” “4” and “5”
the same way you do for “2.” Slowly
let up on the clutch p6dal as you press
the accelerator pedal.
To Stop - Let up on the accelerator
pedal and press the brGke pedal. Just
before
the vehicle stops, press the
clutch pedal and the brake pedal, and
shift to “Neutral.”
Neutral - Use this position when
you start or idle your engine.
R (Reverse) - To back up, press
down the clutch pedal and shift into
“R.” Let up on the clutch pedal slowly
while pressing the accelerator pedal.
You cannot go from
“5” (Fifth Gear) into
“R” (Reverse). If you try, you will be
locked out. You must first shift into
“Neutral,” move the lever to
the left, back
to the right, and then shift into
“R”
(Reverse). This is a safety feature.

1. Hold the brake pedal down with your
right foot and set the parking brake.
2. Move the shift lever into “P” (Park)
position like this:
0 Hold in the button on the lever,
and push the lever all
the way
toward the front of your vehicle.
3. If you have four-wheel drive, be sure
the transfer case is
in a drive gear -
not in “N” (Neutral).
4. Move the key to “LOCK.”
5. Remove the key and take it with you.
If you can walk away from your
vehicle
with the key in your hand,
your vehicle is
in “P” (Park).
Leaving Your Vehicle with the
Engine Running
(AUTOMATIC TRANSMISSION)
A CAUTION:
Xt can be dangerous to leave your
vehicle with the engine running. Your
vehicle could move suddenly if the
shift lever is not fully in “P” (Park)
with the parking brake firmly set.
I€ YOU have four-wheel drive and
your transfer case is in “N” (Neutral),
your vehicle
will be free to roll, even
if your shift lever
is in “F‘” (Park). So
be sure the transfer case is in a drive
gear
- not in “N’ (Neutral).
And, if you leave the vehicle with the
engine running, it
could overheat and
even catch
fie. You or others could
be injured. Don’t leave your vehicle
with the engine running unless
you
have to.
Torque Lock
(AUTOMATIC TRANSMISSION)
If you are parking on a hill and you don’t
shift your transmission into “P” (Park)
properly, the weight
of the vehicle may
put too much force
on the parking pawl in
the transmission. You may find it difficult
to pull the shift lever out of “P” (Park).
This is called ”torque lock.” To prevent
torque lock, set the parking brake and
then shift into “P“ (Park) properly before
you leave the driver‘s seat. To find out
how, see “Shifting into ’P7 (Park)’‘ in the
Index.
When you are ready
to drive, move the
shift lever
out of “P?’ (Park) 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 transmission, so you can pull the
shift lever out of ’bP’’ (Park).
Shifting out of P (Park)
(AUTOMATIC TRANSMISSION)
Your Geo has a brake-transmission shift
interlock. You have
to fully apply your
regular brake before
you can shift from

0 Are there hidden surface obstacles?
Ruts? Logs? Boulders?
0 What’s at the bottom of the hill? Is
there a hidden creek bank or even a
river bottom with large rocks?
If you decide you can go down a
hill
safely, then try to keep your vehicle
headed straight down, and use a low gear.
This way, engine drag can help your
brakes and they won’t have to do all the
work. Descend slowly, keeping your
vehicle under control at all times.
Q: Are there some things I should not
do when driving down
a hill?
A: Yes! These are important because if
you ignore them you could lose
control and have a serious accident.
When driving downhill, avoid turns
that take you across the incline
of the
hill.
A hill that’s not too steep to drive
down may be too steep to drive
across. You could roll over if you
don’t drive straight down.
Never go downhill with the
transmission in “N” (Neutral), or with
the clutch pedal depressed in a manual
shift. This is called “free-wheeling.”
Your brakes will have to do all the
work and could overheat and fade.
Avoid braking
so hard that you lock
the front wheels when going downhill.
If your front wheels are locked, you
can’t steer your vehicle. If your
wheels lock up during downhill
braking, you may feel the vehicle
starting to slide sideways.
To regain
your direction, just ease
off the brakes
and steer to keep the front of the
vehicle pointing straight downhill.
Q: Am I likely to stall when going
downhill?
A:
0
0
0
0
It‘s much more likely to happen going
uphill.
But if it happens going
downhill, here’s what to do.
Stop your vehicle by applying the
regular brakes. Apply the parking
brake.
Shift to
“P” (Park) (or to Neutral with
the manual transmission) and, while
still braking, restart the engine.
Shift back to a low gear, release the
parking brake, and drive straight down.
If the engine won’t start, get out and
get help.
Driving Across an Incline
Sooner or later, an off-road trail will
probably go across the incline
of a hill. If
this happeris, you have to decide whether
to try to drive across the incline. Here are
some things to consider:
0 A hill that can be driven straight up
or down may be too steep to drive
across. When you go straight up or
down a hill, the length
of the wheel
base (the distance from the front
wheels to the rear wheels) reduces the

Your Driving and the Road
passed vehicle before vou can return to
your lane.
Backing Up
Hold the bottom of the steering wheel
with one hand. Then, to move the trailer
to the left, just move that hand to the left.
To move
the trailer to the right, move
your hand to the right. Always back up
slowly and,
if possible, have someone
guide you.
Making Turns
When you’re turning with a trailer, make
wider turns than normal.
Do this so your
trailer won’t strike soft shoulders, curbs,
road signs, trees, or other objects. Avoid
jerky or sudden maneuvers. Signal well
in
advance.
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 lights 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
a manual transmission with fifth gear,
you may prefer not
to use fifth gear. Just
drive in fourth gear (or, as
you need to,
.a lower gear).
Parking on Hills
You really should not park your vehicle,
with a trailer attached, on a hill. If
something goes wrong, your
rig could start
to move. People can be injured, and
both your vehicle and the trailer can be
damaged.
But if you ever have to park
your rig on a
hill, here’s how to do it:
1. Apply your regular brakes, but don’t
shift into
“F’” (Park) yet, or into gear
for a manual transmission.
2. Have someone place chocks under the
3. When the wheel chocks are in place,
release the regular brakes until the
chocks absorb the load.
trailer wheels.
4. Reapply the regular brakes.
Then
apply your parking brake, and then
shift to
‘T” (Park), or “R” (Reverse)
for a manual transmission.
5. If you have a four-wheel-drive
vehicle, be sure the transfer case is
in
a drive gear - not in “N” (Neutral).
6. Release the regular brakes.

Problems on the Road
Engine Overheating
You will find a coolant temperature gage
on your Geo instrument panel.
If Steam Is Coming from Your Engine:
NOTICE:
If your engine catches fire because
you keep driving with no coolant,
your vehicle can be badly damaged.
The costly repairs would not be cov-
ered by your warranty.
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:
0 Climb a long hill on a hot day.
0 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:
