2005 GMC JIMMY automatic transmission

Shifting Into Park (P)
(Automatic Transmission)
{CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll. If
you have left the engine running, the vehicle
can move suddenly. You or others could be
injured. To be sure your vehicle will not move,
even when you are on fairly level ground, use
the steps that follow. With 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. See
Four-Wheel Drive on page 2-30. Always put the
shift lever fully in PARK (P) with the parking
brake rmly set. If you are pulling a trailer, see
Towing a Trailer on page 4-57.
Column Shift Lever
1. Hold the brake pedal down with your right foot and
set the parking brake.
2. Move the shift lever into PARK (P) by pulling the
shift lever toward you and moving it up as far as it
will go.
3. Turn the ignition key to LOCK.
4. Remove the key and take it with you. If you can
leave your vehicle with the key, your vehicle is in
PARK (P).
Console Shift Lever
1. Hold the brake pedal down with your right foot and
set the parking brake.
2. Move the shift lever into PARK (P) by holding in the
button on the lever and pushing the lever all the

Leaving Your Vehicle With the Engine
Running
{CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
If you have four-wheel drive, your vehicle will be
free to roll – even if your lever is in PARK (P) – if
your transfer case is in NEUTRAL. So be sure
the transfer case is in a drive gear – not
NEUTRAL. SeeFour-Wheel Drive on page 2-30.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
your vehicle with the engine running unless you
have to.If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is rmly set before you leave it. After you
have moved the shift lever into PARK (P), hold the
regular brake pedal down. Then, see if you can move
the shift lever away from PARK (P) without rst pulling it
toward you (or pressing the button on a console shift
lever). If you can, it means that the shift lever was
not fully locked into PARK (P).
Torque Lock
If you are parking on a hill and you do not shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl
in the transmission. You may nd it difficult to pull the
shift lever out of PARK (P). This is called torque lock. To
prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the driver’s
seat. To nd out how, seeShifting Into Park (P)
(Automatic Transmission) on page 2-37.
When you are ready to drive, move the shift lever out of
PARK (P) 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 parking pawl in the transmission, so
you can pull the shift lever out of PARK (P).

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.

Running Your Engine While You Are
Parked (Automatic Transmission)
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-40.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard. See
Winter Driving on page 4-38.
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. Do not leave your vehicle when the engine
is running unless you have to. If you have left
the engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P).

{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.

Vehicle Personalization
Memory Seat
If your vehicle has this
feature, the control located
on the outboard side of the
driver’s seat looks like this.Use this memory function to save your seat cushion and
seatback settings by using the following procedure:
1. Adjust the driver’s seat to a safe and comfortable
driving position.
2. Press the SET button and then press and hold
button 1 (for Driver 1) for three seconds. A chime
will sound to let you know that the position has been
stored.
A second seating can be programmed by repeating
the procedure with a second driver and pressing
button 2 for three seconds.
When your vehicle is in PARK (P) for an automatic
transmission or the parking brake is engaged for
a manual transmission, press and release the numbered
memory button you just stored. The seat will move to
the set position. You will hear one chime.

Cruise Control
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This can really help on long
trips. Cruise control does not work at speeds below
about 25 mph (40 km/h).
If you have an automatic transmission and you apply
your brakes, the cruise control will shut off.
If you have a manual transmission and you apply your
brakes or push the clutch pedal, the cruise control
will shut off.{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not use your cruise control on winding roads
or in heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause needless wheel spinning,
and you could lose control. Do not use cruise
control on slippery roads.
3-11

Headlamps on Reminder
A reminder chime will sound when your headlamps or
parking lamps are manually turned on, the driver’s door
is opened and your ignition is in OFF, LOCK, or
ACCESSORY. To turn the chime off, turn the control
counterclockwise or turn the instrument panel brightness
thumbwheel down to the fully dimmed position. In the
automatic mode, the headlamps turn off once the ignition
key is in OFF.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
rst sold in Canada.The DRL system will make your headlamps come
on at reduced brightness when the following conditions
are met:
The ignition is on
the exterior lamp control is in OFF
the sensor detects daytime light
an automatic transmission is not in PARK (P)
the parking brake is released.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won’t be
on. The instrument panel won’t be lit up either.
When it begins to get dark, the headlamps will
automatically switch from DRL to the regular headlamps.
The DRL system on some vehicles may turn off
temporarily while the turn signals are activated.
To idle an automatic transmission vehicle with the DRL
off, put the transmission in PARK (P). To idle a
manual transmission vehicle with the DRL off, set the
parking brake. The DRL will stay off until you shift out of
PARK (P) or release the parking brake.
