New Vehicle “Break-In”
L
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.
See “Towing
a Trailer” in the Index for
more information.
0 Avoid making hard stops for the first
0 Don’t tow a trailer during break-in.
Ignition Positions
Use your key to start your vehicle. The key lets you turn
the ignition switch to five different positions.
I C
A- E
ACCESSORY (A): This position lets you use things
like the radio and the windshield wipers when the
engine is off. Push in
the key and turn it towards you.
Your steering wheel will remain locked, just as it was
before you inserted the key.
ProCarManuals.com

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 position starts your engine.
NOTICE:
If your key seems stuck in LOCK and you can’t
turn it, be sure you are using the correct key; if
so, is it 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.
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:
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.
1. Without pushing the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as your
engine gets warm.

Your vehicle 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 a need to
leave your key in the ignition in
OFF for an extended
period for any reason, 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.
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.
I
I I
I
I NOTICE:
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 (03): 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.
AUTOMATIC OVERDRIVE
(0) 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
(0).
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.

Locking Rear Axle (If Equipped)
If you have this feature, your rear axle can give you
additional traction
on snow, mud, ice, sand or gravel. It
works like a standard axle most of the time, but when
one of the rear wheels has no traction and the other does,
the locking feature will allow the wheel with traction to
move the vehicle.
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
2-WHEEL HIGH (2H) for most normal
driving conditions.
1 NOTICE: I
Driving in the 4-WHEEL HIGH (4H) or
4-WHEEL LOW (4L) positions for a long time
on dry or wet pavement could shorten the life of
your vehicle’s drivetrain.
Front Axle Locking Feature
The front axle locks and unlocks automatically when
you shift the transfer case. Some delay for the axle to
lock or unlock
is normal. If the outside temperature is
very hot, or the vehicle has been used under hard
driving conditions, there may be a slight delay for the
axle to unlock.

Manual Transfer Case
The transfer case shift lever is on the floor to the right of
the driver. Use this lever to shift into and out
of
four-wheel drive.

The front axle portion of the indicator diagram will light
up when you shift into four-wheel drive and the front
axle engages.
Some delay between shifting into four-wheel drive and
the indicator’s lighting is normal. If the front axle light
does not
go out immediately after you shift out of
four-wheel drive, have your dealer check your system.

An indicator near the lever shows you the transfer
case settings:
2-Wheel High (2H): This setting is for driving in most
street and highway situations. Your front axle
is not
engaged in two-wheel drive.
4-Wheel High (4H): This setting engages your front
axle to help drive your vehicle. Use 4H when you need
extra traction, such as
on wet or icy roads, or in most
off-road situations.
Neutral (N): Shift to this setting only when your vehicle
needs to be towed or when using a power take-off.
4-Wheel Low (4L): This setting also engages your front
axle to give you extra power and a higher driveline ratio.
This position should be used only for off-road driving.
You can shift from 2-WHEEL HIGH (2H) to 4-WHEEL
HIGH (4H) or from 4-WHEEL HIGH (4H) to
2-WHEEL HIGH (2H) while the vehicle is moving.
Your front axle may engage faster if you take your foot
off of the accelerator for
a few seconds after you shift.
In extremely cold weather, it may be necessary to stop
or slow the vehicle to shift into 4-WHEEL HIGH (4H). To
shift into or out of 4-WHEEL LOW (4L) or
N (NEUTRAL):
1. Slow the vehicle to a roll, about 1 to 3 mph
(2 to
5 km/h) and shift the transmission into
NEUTRAL (N).
2. Shift the transfer case shift lever in one quick,
continuous motion.
Don’t pause in N
(NEUTRAL) as you shift the transfer
case into 4-WHEEL LOW (4L), or the gears could clash.
Remember that driving in 4-WHEEL HIGH (4H) or
4-WHEEL LOW (4L) may reduce fuel economy. Also,
driving in four-wheel drive on dry pavement could
cause your tires to wear faster and make your transfer
case harder to shift and run noisier.
When your headlamps or parking lamps are on, rotate
the thumb wheel next to the headlamp switch up
to
brighten, and down to dim your transfer case
indicator light.
