2005 GMC JIMMY manual transmission

Up-Shift Light
If you have a manual
transmission, you have a
SHIFT light on your
instrument panel cluster.
This light will show you when to shift to the next higher
gear for best fuel economy.
When this light comes on, you can shift to the next
higher gear if weather, road and traffic conditions let you.
For the best fuel economy, accelerate slowly and shift
when the light comes on.
While you accelerate, it is normal for the light to go on
and off if you quickly change the position of the
accelerator. Ignore the SHIFT light when you downshift.{CAUTION:
If you skip a gear when you downshift, you
could lose control of your vehicle. You could
injure yourself or others. Don’t shift down
more than one gear at a time when you
downshift.
If your vehicle has four-wheel drive and is equipped with
a manual transmission, disregard the up-shift light
when the transfer case is in four-wheel low (4LO).
Four-Wheel Drive
If your vehicle has four-wheel drive, you can send your
engine’s driving power to all four wheels for extra
traction. To get the most satisfaction out of four-wheel
drive, you must be familiar with its operation. Read
the part that follows before using four-wheel drive. You
should use two-wheel high (2HI) for most normal
driving conditions.
Notice:Driving on clean, dry pavement in
four-wheel drive for an extended period of time may
cause premature wear on your vehicle’s powertrain.
Do not drive on clean, dry pavement in four-wheel
drive on pavement for extended periods of time.

Shifting from 2HI or 4HI to 4LO
To shift from 2HI or 4HI to 4LO, the vehicle must be
stopped or moving less than 3 mph (4.8 km/h) with the
transmission in NEUTRAL (N) in vehicles equipped
with an automatic transmission or the clutch pedal
engaged in vehicles equipped with a manual
transmission. The preferred method for shifting into 4LO
is to have your vehicle moving 1 to 2 mph (1.6 to
3.2 km/h). Press and release the 4LO button. You must
wait for the 4LO indicator light to stop ashing and
remain illuminated before shifting your transmission into
gear or releasing the clutch pedal.
If the 4LO button is pressed when your vehicle is in
gear and/or moving, the 4LO indicator light will ash for
30 seconds and not complete the shift unless your
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 4LO, your transmission
indicator switch may require adjustment. With your
transmission in NEUTRAL (N), press and release the
4LO button. While the 4LO indicator light is ashing, shift
your transmission into PARK (P). Wait until the 4LO
indicator light remains illuminated before shifting
your transmission into gear. This will get you into 4LO,
but you should take your vehicle in for service to
restore normal operation.
Shifting from 4LO to 4HI or 2HI
To shift from 4LO to 4HI or 2HI, your vehicle must be
stopped or moving less than 3 mph (4.8 km/h) 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 button. You must
wait for the 4HI indicator light to stop ashing and
remain illuminated before shifting your transmission into
gear or releasing the clutch pedal.
If the 4HI button is pressed when your vehicle is in gear
and/or moving, the 4HI indicator light will ash 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 4HI, your transmission
indicator switch may require adjustment. With your
transmission in NEUTRAL (N), press and release the
4HI button. While the 4HI indicator light is ashing, 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, but you
should take your vehicle in for service to restore
normal operation.

else could be seriously injured. Be sure to set
the parking brake before placing the transfer
case in NEUTRAL. SeeParking Brake on
page 2-36.
NEUTRAL:Shift the vehicle’s transfer case to
NEUTRAL only when towing your vehicle. See

are in. The indicator lights will come on briey when you
turn on the ignition and one will stay on. If the lights
do not come on, you should take your vehicle to your

shifting the transfer case. It will remain illuminated when
the shift is complete. If for some reason the transfer
case cannot make a requested shift, it will return to the
last chosen setting.If the SERVICE 4WD light stays on, you should take
your vehicle to your dealer for service. SeeService
Four-Wheel Drive Warning Light on page 3-36for further

Shifting Out of Park (P)
(Automatic Transmission)
Your vehicle has an automatic transmission shift lock
control system which locks the shift lever in PARK when
the ignition is in the OFF position. In addition, you
have to fully apply the regular brakes before you can
shift from PARK (P) when the ignition is in RUN.
SeeAutomatic Transmission Operation on page 2-25.
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 and
then move the shift lever into the gear you want. You
must press the shift lever button on the shift lever.
If you ever hold the brake pedal down but still cannot
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 the transmission to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear
you want.
5. Have the vehicle xed as soon as you can.
Parking Your Vehicle
(Manual Transmission)
Before you get out of your vehicle, move the shift lever
into REVERSE (R), and rmly apply the parking
brake. Once the shift lever has been placed into
REVERSE (R) with the clutch pedal pressed in, you can
turn the ignition key to OFF, remove the key and
release the clutch.
If you are parking on a hill, or if your vehicle is pulling a
trailer, seeTowing a Trailer on page 4-57.
2-39

{CAUTION:
If you have four-wheel drive, your vehicle will
be free to roll — even if your shift lever is in
PARK (P) — if your transfer case is in
NEUTRAL. So be sure the transfer case is in a
drive gear — not in NEUTRAL. SeeFour-Wheel
Drive on page 2-30.
Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into Park (P) (Automatic
Transmission) on page 2-37.
If you are pulling a trailer, seeTowing a Trailer on
page 4-57.
Mirrors
Manual Rearview Mirror
Pull the tab under the mirror toward you to reduce the
glare from headlamps behind you after dark. Push
the tab away from you for normal daytime operation.
Automatic Dimming Rearview Mirror
If your vehicle has this feature, the mirror automatically
changes to reduce glare from headlamps behind
you. A photocell on the back of the mirror senses when
it is becoming dark outside. Another photocell built
into the mirror surface senses when headlamps
are behind you.
At night, when the glare is too high, the mirror will
gradually darken to reduce glare. This change may take
a few seconds. The mirror will return to its clear
daytime state when the vehicle is put into REVERSE (R)
or when the glare is reduced.
AUTO (Automatic Dimming):This button is located at
the base of the mirror. Use it to turn on the automatic
feature. The button has an indicator light to show it is on.
OFF:Press this button to turn the automatic feature off.
Time Delay
The automatic mirror has a time delay feature which
prevents unnecessary switching from the night back to
the day position. This delay prevents rapid changing
of the mirror as you drive under lights and through traffic.
