Power Door Locks
If your vehicle has power
door locks, the switches
are located on the driver’s
and the front passenger’s
armrests.
Press L (lock) to lock all the doors at once. To unlock
all the doors, press U (unlock).
On crew cab models, use the manual door lock lever on
each rear door to lock or unlock the doors from the
rear seating areas.
Programmable Automatic Door
Locks
If your vehicle has power door locks and the remote
keyless entry system, it has an automatic lock/unlock
feature.
If your vehicle has an automatic transmission, it is
programmed from the factory to lock all doors
automatically when the shift lever is moved out of
PARK (P). All the doors will unlock when the shift lever
is moved back into PARK (P).
If your vehicle has a manual transmission, it is
programmed from the factory to lock all the doors when
the vehicle speed is greater than 15 mph (24 km/h). The
doors will unlock when the key is removed from the
ignition.
To change the automatic door lock and unlock settings,
see “Automatic Door Locks” underDIC Operation
and Displays on page 3-37. Driver’s Switch Shown,

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not 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 rst 500 miles (805 km).
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake or slow the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time the new brake
linings are not 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.
Do not tow a trailer during break-in. SeeTowing
a Trailer on page 4-48for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
Ignition Positions
With the key in the ignition
switch, you can turn to four
different positions.
To shift out of PARK (P), the ignition must be in ON/RUN
and the regular brake pedal must be applied.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the key.
Use the correct key and turn the key only with your
hand. Make sure the key is all the way in. If none of
this works, then your vehicle needs service.
(A) LOCK/OFF:This position locks the ignition. It also
locks the transmission on automatic transmission
vehicles. It locks the steering wheel on manual
transmission vehicles when the key is removed. It is a
theft-deterrent feature. You will only be able to remove
your key when the ignition is turned to LOCK/OFF.
2-19

If you have an automatic transmission, the ignition
switch cannot be turned to LOCK/OFF unless the shift
lever is in PARK (P).
If the steering wheel is locked, move it from right to left
and turn the key to ACC/ACCESSORY. If none of
this works, then your vehicle needs service.
(B) ACC/ACCESSORY:This is the position in which
you can operate your electrical accessories or items
plugged into the accessory power outlets. On automatic
transmission vehicles, this position unlocks the
ignition. On manual transmission vehicles, it unlocks the
ignition and steering wheel. Use this position if your
vehicle must be pushed or towed.
(C) ON/RUN:This is the position that the switch returns
to after you start your engine and release the switch.
The switch stays in ON when the engine is running. But
even when the engine is not running, you can use
ON/RUN to operate the electrical accessories and to
display some instrument panel cluster warning and
indicator lights. The transmission is also unlocked in this
position on automatic transmission vehicles.The battery could be drained if you leave the key in the
ACC/ACCESSORY or ON/RUN position with the engine
off. You may not be able to start your vehicle if the battery
is allowed to drain for an extended period of time.
START (D):This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch returns to ON/RUN for driving.
When the engine is not running, ACC/ACCESSORY
and ON/RUN allows you to operate the electrical
accessories, such as the radio or items plugged into the
accessory power outlets.
A warning tone will sound if you open the driver’s door
when the ignition is in ACC/ACCESSORY or LOCK/OFF
and the key is in the ignition.
2-20

Key In the Ignition
Never leave your vehicle with the keys inside, as it is an
easy target for joy riders or thieves. If you leave the
key in the ignition and park your vehicle, a chime
will sound, when you open the driver’s door. Always
remember to remove your key from the ignition and take
it with you. This will lock your ignition and transmission.
Also, always remember to lock the doors.
The battery could be drained if you leave the key in the
ignition while your vehicle is parked. You may not be
able to start your vehicle after it has been parked for an
extended period of time.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
20 minutes after the engine is turned off:
Audio System
Wipers
Power Windows
These features work when the key is in ON/RUN or
ACC/ACCESSORY. Once the key is turned from
ON/RUN to LOCK/OFF, power to these features
continue to work for up to 20 minutes or until a door is
opened.
Starting the Engine
Place the transmission in the proper gear.
Automatic Transmission
Move the shift lever to P (Park) or N (Neutral). The
engine will not start in any other position. To restart
when you are already moving, use N (Neutral) only.
Notice:Do not try to shift to P (Park) if your vehicle
is moving. If you do, you could damage the
transmission. Shift to P (Park) only when your
vehicle is stopped.
Manual Transmission
The shift lever should be in neutral position and the
parking brake engaged. Hold the clutch pedal down to
the oor and start the engine. Your vehicle will not
start if the clutch pedal is not all the way down. That is
a safety feature.
2-21

Automatic Transmission Operation
Your automatic transmission has a shift lever on the
steering column.
It 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 turned off, but not in LOCK,
there will be a small current drain on your battery which
could discharge your battery over a period of time. If you
need to leave your key in the ignition but not in LOCK for
an extended period, it is recommended that you
disconnect the battery cable from the battery to prevent
discharging your battery.
There are several different positions for your shift lever.PARK (P):This position locks your rear wheels. It is
the best position to use when you start your engine
because your vehicle cannot move easily.
{CAUTION:
It is dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the
parking brake rmly set. The vehicle can roll.
Do not leave the 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 the
vehicle will not move, even when you are on
fairly level ground, always set the parking brake
and move the shift lever to P (Park). SeeShifting
Into Park (Automatic Transmission) on
page 2-34. If you are pulling a trailer, seeTowing
a Trailer on page 4-48.
2-24

Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system. You must fully
apply your regular brakes before you can shift from
PARK (P) when the ignition key is in ON. If you cannot
shift out of PARK (P), ease pressure on the shift
lever by pushing the shift lever all the way into PARK (P)
as you maintain brake application. Then move the
shift lever into another gear. SeeShifting Out of Park
(Automatic Transmission) on page 2-36.
REVERSE (R):Use this gear to back up.
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
To rock your vehicle back and forth to get out of snow,
ice, or sand without damaging your transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 4-31.
NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only.
{CAUTION:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, the
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while the engine is
running at high speed.
Notice:Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage
the transmission. The repairs would not be covered
by the vehicle warranty. Be sure the engine is
not running at high speed when shifting the vehicle.
DRIVE (D):This position is for normal driving. If
provides the best fuel economy for your vehicle. If you
need more power for passing, and you are:
Going less than about 35 mph (55 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You will shift down to the next gear and have more
power.
