Memory Seat, Mirrors, and Pedals
Your vehicle has the memory package.
The controls for this
feature are located on
the driver’s door, and are
used to program and
recall memory settings
for the driver’s seat,
outside mirrors, and the
adjustable throttle and
brake pedal feature, if
your vehicle has it.
To save your positions in memory, do the
following:
1. Adjust the driver’s seat, including the seatback
recliner and lumbar, both outside mirrors, and
the throttle and brake pedals to a comfortable
position.SeeOutside Power Foldaway Mirrors on
page 149andAdjustable Throttle and Brake
Pedal on page 128for more information.
Not all mirrors will have the ability to save and
recall the mirror positions.
2. Press and hold button 1 until two beeps let
you know that the position has been stored.
A second seating, mirror, and throttle and brake
pedal position can be programmed by repeating
the above steps and pressing button 2.
To recall the memory positions, the vehicle must be
in PARK (P). Press and release either button 1 or
button 2 corresponding to the desired driving
position. The seat, outside mirrors, and adjustable
throttle and brake pedals will move to the position
previously stored. You will hear a single beep.

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
your 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. See
Towing a Trailer on page 380for the
trailer towing capabilities of your vehicle
and more information.
Following break-in, engine speed and load can
be gradually increased.
123
Adjustable Throttle and Brake Pedal
Your vehicle has an adjustable throttle and
brake pedal that lets you change their positions.
This feature is designed for shorter drivers,
since the pedals can not move farther away from
the standard position, but can move toward
the driver for better pedal reach.
The feature will not operate when the vehicle is in
REVERSE (R) or while using the cruise control.
The switch used to adjust the pedals is located on
the center console below the climate control
system.
Press the right and left arrows to move the pedals
either closer or further from your body.Your vehicle has a memory function which allows
the pedals to be saved and recalled. See
Memory Seat, Mirrors, and Pedals on page 12for
more information.
Engine Coolant Heater
Your vehicle may have an engine coolant heater.
In very cold weather, 0°F (−18°C) or colder,
the engine coolant heater can help. You will get
easier starting and better fuel economy during
engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C), use of
the coolant heater is not required. Your vehicle
may also have an internal thermostat in the
plug end of the cord. This will prevent operation of
the engine coolant heater when the temperature
is at or above 0°F (−18°C) as noted on the cord.
128
There are several different positions for the 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.
When parked on a hill, especially when the vehicle
has a heavy load, you may notice an increase in the
effort to shift out of PARK (P). See Torque
Lock (Automatic Transmission) underShifting Into
Park (P) on page 138for more information.
{CAUTION:
It is 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). See
Shifting Into Park (P) on page 138.Ifyou
are pulling a trailer, seeTowing a Trailer
on page 380.
130
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your
vehicle is moving forward could damage
the transmission. The repairs would not be
covered by your warranty. 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, seeIf Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow on page 370.
NEUTRAL (N):In this position, your engine does
not connect with the wheels. To restart when
you are already moving, use NEUTRAL (N) only.
Also, use NEUTRAL (N) when your vehicle is
being towed.
{CAUTION:
Shifting into a drive gear while your
engine is running at high speed is
dangerous. Unless your foot is rmly on
the brake pedal, your vehicle could move
very rapidly. You could lose control and
hit people or objects. Do not shift into a
drive gear while your engine is running at
high speed.
Notice:Shifting out of PARK (P) or
NEUTRAL (N) with the engine running at high
speed may damage the transmission. The
repairs would not be covered by your warranty.
Be sure the engine is not running at high
speed when shifting your vehicle.
131
DRIVE (D):This position is for normal driving.
It 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.
By doing this, the vehicle shifts down to the next
gear and has more power.
DRIVE (D) 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 a lower gear selection if the
transmission shifts too often.
Downshifting the transmission in slippery road
conditions could result in skidding, see Skidding
underLoss of Control on page 338MANUAL MODE (M):This position lets drivers
select the range of gears appropriate for current
driving conditions. If your vehicle has this feature,
see Driver Shift Control (DSC) later in this
section.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only the
accelerator pedal may damage the
transmission. If you are stuck, do not spin the
tires. When stopping on a hill, use the
brakes to hold the vehicle in place.
Your vehicle has a shift stabilization feature that
adjusts the transmission shifting to the current
driving conditions in order to reduce rapid upshifts
and downshifts. This shift stabilization feature is
designed to determine, before making an upshift, if
the engine will be able to maintain vehicle
speed by analyzing things such as vehicle speed,
throttle position and vehicle load. If the shift
stabilization feature determines that a current
vehicle speed cannot be maintained, the
transmission does not upshift and instead holds
the current gear. In some cases, this may appear
to be a delayed shift, however the transmission
is operating normally.
132
Grade Braking
Grade Braking assists when driving on a downhill
grade. It maintains the vehicle’s speed by
automatically implementing a shift schedule that
uses the engine and the transmission to slow
the vehicle. This reduces wear on the brakes
system and increases control of the vehicle. The
system constantly monitors the vehicle’s speed,
acceleration, throttle position, and whether
the brake pedal is being pressed, and determines
when to keep the current vehicle speed or to
slow down. The system will then automatically
command downshifts that reduces the vehicles
speed, until the brake pedal is no longer
being pressed. This indicates the desired vehicle
speed has been reached.The tow/haul mode and grade braking shift modes
can be activated by pressing the button on the
end of the shift control stalk. While in the
DSC mode, grade braking is deactivated, allowing
the driver to select a gear.
SeeAutomatic Transmission Operation on
page 129for more information.
Parking Brake
To set the parking brake, hold the regular brake
pedal down with your right foot. Push down
the parking brake pedal with your left foot.
