rain, traveling into strong head winds, or while tow-
ing heavy trailers.
NOTE:
•
If the vehicle is started in cold temperatures, shifts into
Overdrive may be delayed. Normal Overdrive and
shifting operation will resume when the temperature
of the transmission reaches the appropriate tempera-
ture. Refer to the “Note” under “Torque Converter
Clutch” later in this section.
•If the transmission temperature gets too hot, the
transmission may downshift out of Overdrive or en-
gage overdrive at higher vehicle speeds until the
transmission cools down. After cooldown, Overdrive
will resume normal operation.
3 (Third)
This range eliminates shifts into Overdrive. The trans-
mission will operate normally in First, Second and
Third while in this range. The “3” position should also
be used when descending steep grades to prevent
brake system distress.NOTE:
Using the “3” range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up.
L (Low)
This range should be used for engine braking when
descending very steep grades. In this range, upshifts will
occur only to prevent engine overspeed while downshifts
occur earlier than other gear range selections.
CAUTION!
Never race the engine with the brakes on and the
vehicle in gear, and never hold the vehicle on an
incline without applying the brakes. These practices
can cause overheating and damage to the transmission.
Torque Converter Clutch
A feature designed to improve fuel economy has been
added to the automatic transmission of this vehicle. A

WARNING!
Never use Park position on an automatic transmis-
sion as a substitute for the parking brake. Always
apply parking brake fully when parked to guard
against vehicle movement and possible injury or
damage.
The following indicators should be used to ensure that
you have engaged the selector lever into the P (Park)
position:
•When shifting into P (Park) move the lever all the way
forward until it stops, and is fully seated.
•Look at the shift indicator display on the instrument
panel to ensure it is in the P (Park) position.
CAUTION!
Damage to the shifter could result if the selector
lever is moved out of P (Park) before the ignition is
turned from the LOCK to ON position.
R (Reverse)
Shift into R (Reverse) gear only when the vehicle is
completely stopped.
N (Neutral)
No power is transmitted from the engine to the drive
axle. When the brakes are released, the vehicle can be
moved freely (pushed or towed). Do not engage N
(Neutral) position while driving except to coast when
the vehicle is in danger of skidding (e.g., on icy roads).
The engine may be started in this range. Use this range
for starting your vehicle if it is moving or being towed.
CAUTION!
Coasting the vehicle, or driving for any other reason
with selector lever in NEUTRAL can result in trans-
mission damage.

BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems loses normal capability, the remaining
system will still function. There will be some
loss of overall braking effectiveness. This may be evident
by increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake Warning Light.
In the event power assist is lost for any reason (for
example, repeated brake applications with the engine off)
the brakes will still function. The effort required to brake
the vehicle will be much greater than that required with
the power system operating.
Anti-Lock Brake System — If Equipped
The Anti-Lock Brake System provides increased vehicle
stability and brake performance under most braking
conditions. The system automatically “pumps” the
brakes during severe braking conditions to prevent
wheel lock-up.The electronic brake force distribution (EBD) prevents the
rear wheels from over-braking and provides greater
control of available braking forces applied to the rear
axle.
When the vehicle is driven over 7 mph (11 km/h), you
may also hear a slight clicking sound as well as some
related motor noises. These noises are the system per-
forming its self check cycle to ensure that the ABS system
is working properly. This self check occurs each time the
vehicle is started and accelerated past 7 mph (11 km/h).
ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.

You also may experience the following when the brake
system goes into Anti-lock:
•The ABS motor running (it may continue to run for a
short time after the stop),
•the clicking sound of solenoid valves,
•brake pedal pulsations,
•and a slight drop or fall away of the brake pedal at the
end of the stop.
These are all normal characteristics of ABS.
WARNING!
•The Anti-Lock Brake System contains sophisticated elec-
tronic equipment that may be susceptible to interference
caused by improperly installed or high output radio
transmitting equipment. This interference can cause pos-
sible loss of anti-lock braking capability. Installation of
such equipment should be performed by qualified pro-
fessionals.
•Pumping of the Anti-Lock Brakes will diminish their
effectiveness and may lead to an accident. Pumping
makes the stopping distance longer. Just press firmly on
your brake pedal when you need to slow down or stop.
•Anti-lock system (ABS) cannot prevent the natural laws
of physics from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded by
the condition of the vehicle brakes and tires or the
traction afforded.
•The ABS cannot prevent accidents, including those re-
sulting from excessive speed in turns, following another
vehicle too closely, or hydroplaning. Only a safe, atten-
tive, and skillful driver can prevent accidents.
•The capabilities of an ABS equipped vehicle must never
be exploited in a reckless or dangerous manner, which
could jeopardize the user’s safety or the safety of others.

All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
Anti-Lock Brake Light
The ABS light monitors the Anti-Lock Brake Sys-
tem. The light will come on when the ignition
switch is turned to the ON position and may stay on for
as long as four seconds.
If the ABS light remains on or comes on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not come on when the
Ignition switch is turned to the ON position, have the
bulb repaired as soon as possible.
If both the Brake Warning Light and the ABS Light
remain on, the Anti-Lock brakes (ABS) and ElectronicBrake Force Distribution (EBD) systems are not function-
ing. Immediate repair to the ABS system is required.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:Increased noise levels at the end of the steering
wheel travel are considered normal and do not indicate
that there is a problem with the power steering system.
Upon initial start-up in cold weather, the power
steering pump may make noise for a short amount of
time. This is due to the cold, thick fluid in the steering
system. This noise should be considered normal, and
does not in any way damage the steering system.

The Brake Assist System (BAS) is standard on vehicles
equipped with Electronic Stability Program (ESP). The
BAS is designed to optimize the vehicle’s braking capa-
bility during emergency braking maneuvers. The system
applies optimum pressure to the brakes in emergency
braking conditions than might otherwise be afforded
solely by the driver’s braking style. This can help reduce
braking distances. The BAS complements the Anti-Lock
Brake System (ABS). Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit of
the system, you must apply continuous braking power
during the stopping sequence. Do not reduce brake pedal
pressure. Once the brake pedal is released, the BAS is
deactivated.ELECTRONIC STABILITY PROGRAM (ESP) — IF
EQUIPPED
WARNING!
The ESP (Electronic Stability Program) cannot pre-
vent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. The ESP cannot prevent
accidents, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of an
ESP-equipped vehicle must never be exploited in a
reckless or dangerous manner, which could jeopar-
dize the user’s safety or the safety of others.
This system enhances directional control and stability of
the vehicle under various driving conditions. The ESP
corrects for oversteering and understeering the vehicle
by applying the brake of the appropriate wheel. Engine

When ESP is switched off, the engine torque reduction
feature is cancelled. Therefore, the enhanced vehicle
stability offered by ESP is unavailable. However, a fea-
ture of the system remains active. This feature controls
wheel spin across an axle quite similarly to a limited slip
differential. If one wheel on an axle is spinning faster
than the other, the system will apply the brake of the
spinning wheel and allow more engine torque to be
applied to the wheel that is not spinning. This wheel slip
control is active at vehicle speeds between approximately
24 mph (40 km/h) and 50 mph (80 km/h).
CAUTION!
When the ESP/TCS indicator light is illuminated
continuously, the ESP is switched off. Avoid spin-
ning one drive wheel. This may cause serious dam-
age to the drive train.
CAUTION!
If the vehicle is towed with the front axle raised, the
engine must be shut off (key in the ignition switch to
the OFF/LOCK or ACC position). Otherwise, the ESP
will immediately be engaged and will apply the rear
wheel brakes.
Synchronizing ESP
The malfunction indicator light for the ESP is
combined with BAS indicator. If the power
supply is interrupted (battery disconnected or
discharged), the ESP/BAS malfunction indica-
tor light may illuminate with the engine running. If this
should occur, turn the steering wheel completely to the
left and then to the right. The ESP/BAS malfunction
indicator light should go out. However, if the light
remains on, have the ESP and BAS checked at your
authorized dealer as soon as possible.

Loading
To load your vehicle properly, first figure out its empty
weight, axle by axle and side by side. Store heavier items
down low and be sure you distribute their weight as
evenly as possible. Stow all loose items securely before
driving. If weighing the loaded vehicle shows that you
have exceeded either GAWR, but the total load is within
the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
A loaded vehicle is shown in the illustration. Note that
neither the GVWR nor the GAWR capacities have been
exceeded.

Towing Requirements
To promote proper break-in of your new vehicle driv-
etrain components the following guidelines are recom-
mended:
CAUTION!
•Avoid towing a trailer for the first 500 miles (805
km) of vehicle operation. Doing so may damage
your vehicle.
•During the first 500 miles (805 km) of trailer
towing, limit your speed to 50 mph (80 km/h).
Perform the maintenance listed in Section 8 of this
manual. When towing a trailer, never exceed the GAWR,
or GCWR, ratings.
WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Make certain that the load is secured in the trailer
and it will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
•When hauling cargo, or towing a trailer, do not
overload your vehicle or trailer. Overloading can cause
a loss of control, poor performance, or damage to
brakes, axle, engine, transmission, steering, suspen-
sion, chassis structure, or tires.
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.

Towing Requirements — Trailer Brakes

Donotinterconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
An electronically actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers over 1,000
lbs (454 kg) and required for trailers in excess of 2,000
lbs (907 kg).
CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes, and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
Do not connect trailer brakes to your vehicle’s hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have an accident.
Towing any trailer will increase your stopping dis-
tance. When towing, you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.
