Key in the Ignition
If you leave your vehicle with the keys inside, it’s an
easy target for
joy riders or professional thieves -- so
don’t do it.
When you park your vehicle and open the driver’s door, you’ll hear a tone reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and
so will your
ignition.
If you have an automatic transmission, taking
your key out also locks your transmission. And
remember to lock the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember
to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
If you park in a lot where someone will be watching
your vehicle, it’s best to lock it
up and take your keys.
But what
if you have to leave your ignition key? What if
you have to leave something valuable in your vehicle?
Put your valuables in a storage area, like your
glove box.
Lock all the doors except the driver’s.
New Vehicle “Break-In”
NOTICE:
Your modern vehicle doesn’t need an elaborate
“break-in.” But it will perform better in the long
run
if you follow these guidelines:
Keep your speed at 55 mph (88 km/h) or
less for the first
500 miles (805 km).
Don’t drive at any one speed -- fast or
slow
-- for the first 500 miles (805 km).
Don’t make full-throttle starts.
200 miles (322 km) or so. During this time
your new brake linings aren’t yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every
time you get new brake linings.
0 Don’t tow a trailer during break-in. See
“Towing a Trailer’’ in the Index for
more information.
a Avoid making hard stops for the first

If your vehcle is equipped with an automatic transmission,
it now features an electronic shift position indicator within
the instrument cluster. This display must be powered
anytime the
shift lever is capable of being moved out of
PARK (P). This means that if your key is in OFF, rather
than
LOCK, there will be a small current drain on your
battery which could discharge your battery over
a period
of time. If you have to leave your key in the
ignition
in OFF for an extended period, it is recommended
that you disconnect the battery cable from the battery to
prevent discharging your battery.
PARK
(P): This locks your rear wheels. It’s the best
position to use when you start your engine because your
vehicle can’t move easily.
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK
(P) with the
parking brake firmly set. Your vehicle can roll.
CAUTION: (Continued)
I
Don’t 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 won’t move, even when you’re on fairly
level ground,
always set your parking brake and
move the shift lever to PARK
(P).
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
(N). So, be sure the transfer case is in
a drive gear, two-wheel high
(2H) or four-wheel
high
(4H) or four-wheel low (4L) -- not in
NEUTRAL
(N). See “Shifting Into PARK (P)” in
the Index.
If you’re pulling a trailer, see “Towing
a Trailer” in the Index.

REVERSE (R): Use this gear to back up.
~OTICE:
r
~~
Shifting to REVERSE (R) while your vehicle is
moving forward could damage your transmission.
Shift to
REVERSE (R) only after your vehicle
is stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transmission, see
“Stuck: In Sand, Mud, Ice or Snow”
in the Index.
NEUTRAL
(N): In this position, your engine
doesn’t connect
with the wheels. To restart when you’re
already moving, use
NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed. Shifting out
of PARK
(P) or NEUTRAL (N) while
your engine is “racing” (running at high speed) is
dangerous. Unless your foot
is firmly on the
brake pedal, your vehicle could move
very
rapidly. You could lose control and hit people
or objects. Don’t shift out
of PARK (P) or
NEUTRAL
(N) while your engine is racing.
NOTICE:
Damage to your transmission caused by shifting
out
of PARK (P) or NEUTRAL (N) with the
engine racing isn’t covered by your warranty.

AUTOMATIC OVERDRIVE (@): This position is for
normal driving. If you need more power for passing, and
you’re:
Going less than about 35 mph (56 km/h), push your
Going about 35 mph (56 km/h) or more, push the
accelerator
pedal about halfway down.
accelerator all
the way down.
You’ll shift down to the next gear and have more power.
AUTOMATIC OVERDRIVE
(a) can be used when
towing
a trailer, carrying a heavy load, driving on steep
hills or for off-road driving.
You may want to shift the
transmission to THIRD
(3) or, if necessary, a lower gear
selection if the transmission shifts too often.
THIRD (3): This position is also used for normal
driving, however it offers more power and lower
fuel
economy than AUTOMATIC OVERDRIVE (a).
SECOND (2): This position gives you more power but
lower fuel economy.
You can use SECOND (2) on hills.
It can help control your speed as you go down steep
mountain roads, but then you would also want
to use
your brakes
off and on.
If you manually select SECOND (2)’ the transmission will
drive in
second gear. You may use this feature for reducing torque to the rear wheels when you are trying
to start your
vehicle from a stop on slippery road surfaces.
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 (1) while the vehicle is
moving forward,
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 accelerator
pedal. This could overheat and damage the
transmission. Use your brakes or shift into
PARK (P) to hold your vehicle in position
on a hill.

To stop, let up on the accelerator pedal and press the
brake pedal. Just before the vehicle stops, press the
clutch pedal and the brake pedal, and shift
to
NEUTRAL (N).
NEUTRAL (N): Use this position when you start or
idle your engine.
REVERSE (R): To back up, first press down the clutch
pedal. Wait about
five seconds for the internal parts to
stop spinning and then shift into REVERSE
(R).
Let up on the clutch pedal slowly while pressing the
accelerator pedal.
NOTICE:
Shift to REVERSE (R) only after your vehicle is
stopped. Shifting to REVERSE (R) while your
vehicle
is moving could damage your transmission.
Also, use REVERSE (R), along with the parking brake,
when turning off your engine and parking your vehicle.
5-Speed (MG5M50 Transmissions Without
Low Gear) (If Equipped)
Here’s how to operate your transmission:
FIRST (1): Press the clutch pedal and shift into
FIRST (1). Then, slowly let up on the clutch pedal as
you press
the accelerator pedal.
You can
shift into FIRST (1) 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 FIRST
(I), put the shift
lever
in NEUTRAL (N) and let up on the clutch. Press
the clutch pedal back down. Then shift into FIRST (1).
SECOND (2): Press the clutch pedal as you let up on
the accelerator pedal and shift into
SECOND (2). Then,
slowly let up on the clutch pedal as you press the
accelerator pedal.
THIRD (3), FOURTH (4) and FIFTH (5): Shift into
THIRD
(3), FOURTH (4) and FIFTH (5) the same way
you do for
SECOND (2). Slowly let up on the clutch
pedal as you press the accelerator pedal.
To stop, let up on the accelerator pedal and press the
brake pedal. Just before the vehicle stops, press the
clutch pedal and the brake pedal, and shift to NEUTRAL
(N).

pedal. Wait about five seconds for the internal parts
to
stop spinning and then, shift into REVERSE (R).
Let up on the clutch pedal slowly while pressing the
accelerator pedal.
)NOTICE:
Shift to REVERSE (R) only after your vehicle is
stopped. Shifting to REVERSE
(R) while your
vehicle is moving could damage your transmission.
Also, use REVERSE (R), along with the parking brake,
when turning off your engine and parking your vehicle.
A CAUTION:
If you skip more than one gear when you
downshift, you could
lose control of your vehicle.
And you could injure yourself or others. Don’t shift down more than one gear when you downshift.
~~ ~
If your speed drops below 20 mph (32 kmh), or if the
engine is not running smoothly, you should downshift to
the next lower gear.
You may have to downshift two or
more gears to keep the engine running smoothly or for
good performance.

your rear brakes to overheat. You may have to replace them, and you could also damage other
parts
of your vehicle. Always check to be sure
your parking brake is fully released before
you drive.
If you are towing a trailer and are parking on any hill,
see “Towing
a Trailer’’ in the Index. That section shows
what to do first to keep the trailer from moving.
If you have
a 3500 HD model, it is recommended that
the propshaft mounted parking brake be burnished as
part of the new vehicle break-in. The parking brake
will work best after
it has been burnished following
these instructions.
Make
10 stops, using the parking brake foot pedal, from
20 mph (32 kmh) about 2 112 miles (4 km) apart. In
between stops, drive the vehicle at
20 mph (32 kmk).

when you’re on fairly level ground, use the steps
that follow. If you have four-wheel drive and
your transfer case
is in NEUTRAL (N), your
vehicle will be free to roll, even if your shift lever
is in PARK (P). So, be sure the transfer case is
in a drive gear
-- not in NEUTRAL (N). If
you’re pulling a trailer, see “Towing
a Trailer”
in the Index.
2. Move the shift lever into PARK (P) position like this:
Pull the lever toward you.
