Theft Parking at Night
Vehicle theft is big business, especially in some
cities. Although your vehicle has a number of
theft-deterrent features, we know that nothing we
put
on it can make it impossible to steal. However,
there are ways you can help.
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 and transmission. And remember to lock
the doors. 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.

LOCK (B): This position locks your ignition, steering
wheel and transmission. It’s
a theft-deterrent feature.
You will only be able to remove your key when the
ignition is turned to
LOCK.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. It doesn’t lock the steering
wheel like LOCK.
Use OFF if you must have your
vehicle in motion while the engine is off (for example,
if your vehicle is being pushed).
RUN (D): This is the position for driving.
START (E): This starts your engine. .. -

I NOTICE:
Starting Your Gasoline Engine
If you have a diesel engine, see “Starting Your Diesel
Engine”
in the Diesel Engine Supplement.
Move your shift lever
to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position -- that’s a
safety feature. To restart when you’re already moving,
use
NEUTRAL (N) only.
NOTICE:
I
Don’t try to shift to PARK (P) if your vehicle
is moving.
If you do, you could damage the
transmission. Shift to
PARK (P) only when
your vehicle is stopped.
If your key seems stuck in LOCK and you can’t
turn it, be sure it is all the
way in. If it is, then
turn the steering wheel left and right while you
turn the key hard. But turn the key only with
your hand. Using
a tool to force it could break
the key
or the ignition switch. If none of this
works, then your vehicle needs service.

Automatic Transmission Operation
There are several different positions for your shift lever.
If your vehicle 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 the PARK (P) position. This lneans
that
if your key is in the OFF position, but not locked,
there
will be a small current drain on your battery which
could discharge
your battery over a period of time. If
you have
a need to leave your key in the ignition in the
OFF position for an extended period for any reason, it is
recomnlended that you disconnect the battery cable from
the battery to prevent discharging yo~~r 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.
A CAUTION:
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.
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).
See “Shifting Into PARK (P)” in the Index. If
you’re pulling a trailer, see “Towing a Trailer”
in the Index.
Your vehicle has
a brake-transmission shift interlock.
With the ignition in the RUN position, you must fully
apply your regular brakes before you can shift from
PARK
(P).

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.
ProCarManuals.com

DRIVE (D): 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
accelerator pedal about halfway down.
Going about 35 mph (56 km/h) or more, push the
accelerator all the way down.
You’ll shift down to the next gear and have more power.
You should use DRIVE
(D) (or, as you need to, a lower
gear) when towing
a trailer. Operating your vehicle in
DRIVE (D) when towing a trailer will minimize heat
build-up and extend the life of your transmission.
THIRD (3): This position is also used for normal
driving, however,
it offers more power and lower fuel
economy than DRIVE
(D). You should use THIRD (3)
when carrying a heavy load or driving on steep hills.
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 surfdces.
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)’ the transmission
won’t shift into first gear
until the vehicle is going
slowly enough.
w
NOTICE:
If your rear wheels can’t rotate, don’t try to
drive. This might happen if you are stuck in
very deep sand or mud
or are 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.

Leaving Your Vehicle With the
Enf;?e Rurr-;-y
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 firmly set. And, if
you
leave the vehicle with the engine running, it could
overheat and even catch fire. You or others could
be injured. Don’t leave your vehicle with the
engine running unless you have to.
Torque Lock
If you are parking on a hill and you don’t 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 find 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 find out how, see “Shifting Into
PARK
(P)” in the Index. 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 transmission,
so you can pull the shift
lever out of PARK
(P).
Shifting Out of PARK (P)
Your vehicle has a brake-transmission shift interlock
system.
You have to fully apply your regular brakes
before
you can shift from PARK (P). See “Automatic
Transmission” in the Index.
If
you cannot shift out of PARK (P), ease pressure on
the shift lever and push the shift lever all the way up
into PARK
(P) as you maintain brake application. Then,
move the shift lever into the gear you want.
If
you ever hold the brake pedal down but still can’t
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 to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear you
5. Have the brake-transmission shift interlock system
want.

Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system and
transmission. These parts can work hard on
mountain roads.
Know how
to go down hills. The most important
thing to know is this: let your engine do some
of the
slowing down. Shift
to a lower gear when you go
down a steep or long hill.
A CAUTION:
If you don’t shift down, your brakes could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down a hill
You could crash. Shift down to let your engine
assist your brakes on
a steep downhill slope. Coasting
downhill in
NEUTRAL (N) or with the
ignition
off is dangerous. Your brakes will have to
do all the work
of slowing down. They could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down a hill.
You could crash. Always have your engine running
and your vehicle in gear when you go downhill.

Know how tb go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine
and transmission, and you can climb the
hill better.
Stay
in your own lane when driving on two-lane
roads
in hills or mountains. Don’t swing wide or
cut across the center of
the road. Drive at speeds
that let
YOLI stay in your own lane.
As you go over the top of a hill, be alert. There could be
something
in your lane, like a stalled car or an accident.
You may see highway signs on mountains that warn of
special problems. Examples are long grades, passing or
no-passing zones,
a falling rocks area or winding
roads. Be ale1-f to these and take appropriate action.

If You Do Decide To Pull A Trailer
If you do, here are some important points:

There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
your rig will be legal, not
only where you live but
also where you’ll be driving. A good source for this
information can be state or provincial police.
Consider using a sway control if your trailer will
weigh
4,000 lbs. (1 800 kg) or less. You should
always
use a sway control if your trailer will weigh
more than
4,000 lbs. (1 800 kg). You can ask a hitch
dealer about sway controls.
Don’t tow a trailer at all during
the first 500 miles
(800 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
0

Then, during the first 500 miles (800 km) that you
tow a trailer, don’t drive over
50 mph (80 kdh) and
don’t make starts at full throttle. This helps your
engine and other parts
of your vehicle wear in at the
heavier loads.
You should use DRIVE (D) (or, as you need to,
a lower gear) when towing a trailer. Operating
your vehicle in
DRIVE (D) when towing a trailer
will minimize heat build-up and extend the life
of
your transmission.
Three important considerations have to do with weight:
the weight of the trailer,
the weight of
the trailer tongue
and the weight on your vehicle’s tires. I

Driving On Grades
Reduce speed and shift to a:lower gear before you start
down a long or steep doyngrade. 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.
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a
lower temperature than
at normal altitudes. If you turn
your engine
off immediately after towing at high altitude
on steep uphill grades,
your vehicle may show signs
similar to engine overheating.
To avoid this, let the
engine run while parked (preferably on level ground)
with the automatic transmission in PARK
(P) for a few
minutes before turning the engine off.. If
you do get the
overheat warning, see “Engine Overheating” in the Index.
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
PARK
(P) yet. Then turn your wheels into the curb
if facing downhill or into traffic if facing ,uphill.
2. Have someone place chocks under the trailer wheels. I
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Re-apply the regular brakes. Then apply your
parking brake and then shift to
PARK (P).
5. Release the regular brakes.
ProCarManuals.com

When You Are Ready to Leave After
Parking
on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine:
Shift into a gear: and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important
in trailer
operation are automatic transmission
fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system
and brake adjustment. Each
of these is covered in this
manual, and the Index will help
you find them quickly.
If you‘re trailering, it‘s a good idea to review these
sections before you start your trip.
Check periodically to see that
all hitch nuts and bolts
are tight.
Trailer Wiring Harness
The eight-wire harness, if you have one, is stored under
your vehicle along the rear frame crossmember.
It is
wrapped and bound with a plastic strap. The harness has
a 30-anlp battery feed and no connector, and you should
have a qualified electrical service person wire your
harness for you. Attach the harness
to the trailer, then
tape or strap
it to your vehicle’s frame rail. Be sure you
leave
it loose enough so the wiring doesn’t bend or
break, but not
so loose that it drags on the ground.
Store the harness
in its original place. Wrap the harness
together and tie
it neatly so it won’t be damaged.
The five-wire harness,
if you have one, is stored inside
the vehicle at the passenger side rear corner, behind the
jack. This should be wired by a qualified electrical
service person. It must be routed out
of your vehicle
between the rear door and the floor,
with enough of the
harness left on both sides
so that the trailer or the body
won’t pull
it.
Store the harness in its original place. Wrap the harness
together and tie
it neatly so it won’t be damaged.
