The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer/retailer
in the area where you will be
parking the vehicle for the best
advice on this.
Automatic Transmission
Operation
The shift lever is located on the
center console between the
front seats.
There are several different positions
for the shift lever. When the
position of the shift lever is changed,a message is shown in the Driver
Information Center (DIC). The
selected gear is magnied in the
DIC, and changes according to the
shift lever’s movement. There
are also messages for Sport Shift
Mode, Normal Shift Mode and Driver
Shift Control.
P (Park):This position locks the
rear wheels. It is the best position
to use when the engine is started
because the vehicle cannot
move easily.

Parking Over Things
That Burn
{CAUTION
Things that can burn could touch
hot exhaust parts under the vehicle
and ignite. Do not park over
papers, leaves, dry grass, or other
things that can burn.
Engine Exhaust
{CAUTION
Engine exhaust contains Carbon
Monoxide (CO) which cannot be
seen or smelled. Exposure to CO
can cause unconsciousness and
even death.
Exhaust may enter the vehicle if:
The vehicle idles in areas
with poor ventilation (parking
garages, tunnels, deep snow
that may block underbody
airow or tail pipes).
The exhaust smells or
sounds strange or different.
(Continued)
8-14 Driving and Operating

CAUTION (Continued)
The exhaust system leaks
due to corrosion or damage.
The vehicle’s exhaust system
has been modied, damaged
or improperly repaired.
There are holes or openings
in the vehicle body from
damage or after-market
modications that are not
completely sealed.
If unusual fumes are detected or if
it is suspected that exhaust is
coming into the vehicle:
Drive it only with the windows
completely down.
Have the vehicle repaired
immediately.
Never park the vehicle with the
engine running in an enclosed
area such as a garage or a
building that has no fresh air
ventilation.
Running the Vehicle
While Parked
It is better not to park with the
engine running. But if you ever have
to, here are some things to know.
{CAUTION
Idling a vehicle in an enclosed
area with poor ventilation is
dangerous. Engine exhaust may
enter the vehicle. Engine exhaust
contains Carbon Monoxide (CO)
which cannot be seen or smelled.
It can cause unconsciousness
and even death. Never run the
engine in an enclosed area that
has no fresh air ventilation. For
more information, see Engine
ExhaustEngine Exhaust on
page 8-14.
{CAUTION
It can be dangerous to get out
of the vehicle if the automatic
transmission 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).
Follow the proper steps to be sure
the vehicle will not move. See
Shifting Into Park (Automatic
Transmission) on page 8-12.

on page 9-89.
Driving and Operating 8-15

Rocking Your Vehicle to
Get It Out
Turn the steering wheel left and right
to clear the area around the front
wheels. Turn off any stability system.
Shift back and forth between
R (Reverse) and a forward gear,
spinning the wheels as little as
possible. To prevent transmission
wear, wait until the wheels stop
spinning before shifting gears.
Release the accelerator pedal while
shifting, and press lightly on the
accelerator pedal when the
transmission is in gear. Slowly
spinning the wheels in the forward
and reverse directions causes a
rocking motion that could free the
vehicle. If that does not get the
vehicle out after a few tries, it might
need to be towed out. If the vehicle
does need to be towed out, see
Towing Your Vehicle on page 9-88.
Loading the Vehicle
It is very important to know how
much weight the vehicle can
carry. This weight is called the
vehicle capacity weight and
includes the weight of all
occupants, cargo and all
nonfactory-installed options.
Two labels on the vehicle show
how much weight it may
properly carry, the Tire and
Loading Information label and
the Certication label.{CAUTION
Do not load the vehicle any
heavier than the Gross Vehicle
Weight Rating (GVWR), or
either the maximum front or
rear Gross Axle Weight Rating
(GAWR). If you do, parts on
the vehicle can break, and it
can change the way your
vehicle handles. These could
cause you to lose control and
crash. Also, overloading can
shorten the life of the vehicle.
8-30 Driving and Operating

5.Determine the combined
weight of luggage and
cargo being loaded on the
vehicle. That weight may not
safely exceed the available
cargo and luggage load
capacity calculated in Step 4.
6.If your vehicle will be towing a
trailer, the load from your
trailer will be transferred to
your vehicle. Consult
this manual to determine how
this reduces the available
cargo and luggage load
capacity of your vehicle.
SeeTowing a Trailer on
page 9-89for important
information on towing a trailer,
towing safety rules and
trailering tips.
A.Vehicle Capacity Weight for
Example 1=1,000 lbs
(453 kg).
B.Subtract Occupant Weight
150 lbs (68 kg)×2=300 lbs
(136 kg).
C.Available Occupant and
Cargo Weight=700 lbs
(317 kg).
A.Vehicle Capacity Weight for
Example 2=1,000 lbs
(453 kg).
B.Subtract Occupant Weight
150 lbs (68 kg)×5=750 lbs
(340 kg).
C.Available Cargo
Weight=250 lbs (113 kg).

8-32 Driving and Operating

Gasoline Octane
If the vehicle has a V8 engine, use
regular unleaded gasoline with a
posted octane rating of 87 or higher.
If the octane rating is less than 87,
you might notice an audible knocking
noise when you drive, commonly
referred to as spark knock. If this
occurs, use a gasoline rated at 87
octane or higher as soon as possible.
If you are using gasoline rated at 87
octane or higher and you hear heavy
knocking, the engine needs service.
If the vehicle has the 3.6L V6 engine
(VIN Code 7), use regular unleaded
gasoline with a posted octane rating
of 87 or higher. For best performance
or trailer towing, you could choose
to use middle grade 89 octane
unleaded gasoline. If the octane
rating is less than 87, you might
notice an audible knocking noise
when you drive, commonly referredto as spark knock. If this occurs,
use a gasoline rated at 87 octane
or higher as soon as possible. If you
are using gasoline rated at
87 octane or higher and you hear
heavy knocking, the engine needs
service.
Gasoline Specications
At a minimum, gasoline should
meet ASTM specication D 4814
in the United States or
CAN/CGSB-3.5 or 3.511 in Canada.
Some gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. SeeAdditives on
page 8-36for additional information.
California Fuel
If the vehicle is certied to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specications. See
the underhood emission control
label. If this fuel is not available in
states adopting California emissions
standards, the vehicle will operate
satisfactorily on fuels meeting federal
specications, but emission control
system performance might be
affected. The malfunction indicator
lamp could turn on and the vehicle
might fail a smog-check test. See
Malfunction Indicator Lamp on
page 4-18. If this occurs, return to
your authorized dealer/retailer for
diagnosis. If it is determined that the
condition is caused by the type of
fuel used, repairs might not be
covered by the vehicle warranty.
