CAUTION!
•To avoid damage to the roof rack and vehicle, do not
exceed the maximum roof rack load capacity of 150
lbs (68 kg). Always distribute heavy loads as evenly
as possible and secure the load appropriately.
•Long loads, which extend over the windshield, such
as wood panels or surfboards, or loads with large
frontal area should be secured to both the front and
rear of the vehicle.
•Travel at reduced speeds and turn corners carefully
when carrying large or heavy loads on the roof rack.
Wind forces, due to natural causes or nearby truck
traffic, can add sudden upward loads. This is espe-
cially true on large flat loads and may result in
damage to the cargo or your vehicle.
•Do not use the pop-up feature of the sliding / pop-up
roof when positioning or placing luggage above it, to
prevent damage to the sliding / pop-up roof panel.
WARNING!
Cargo must be securely tied before driving your
vehicle. Improperly secured loads can fly off the
vehicle, particularly at high speeds, resulting in
personal injury or property damage. Follow the Roof
Rack Cautions when carrying cargo on your roof
rack.
LOAD LEVELING SYSTEM — IF EQUIPPED
The automatic load leveling system will provide a level-
riding vehicle under most passenger and cargo loading
conditions.
A hydraulic pump contained within the shock absorbers
raises the rear of the vehicle to the correct height. It takes
approximately 1 mile (1.6 km) of driving for the leveling
to complete depending on road surface conditions.
If the leveled vehicle is not moved for approximately 15
hours, the leveling system will bleed itself down. The
vehicle must be driven to reset the system.

NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
Immediate repair is necessary if brake failure is indicated.
WARNING!
Driving a vehicle with the brake light on is danger-
ous. Part of the brake system may have failed. It will
take longer to stop the vehicle. You could have an
accident. Have the vehicle checked immediately.
Vehicles equipped with Anti-Lock brakes (ABS) are also
equipped with Electronic Brake Force Distribution (EBD).
Both the Brake Warning Light and the ABS Light will
turn on in the event of an EBD failure. Immediate repair
of the ABS system is required in the event of an EBD
failure.
The operation of the Brake Warning Light can be checked
by turning the ignition switch from the OFF position tothe ON position. The light should turn on for approxi-
mately two seconds and then turn off. The light will
remain on if the parking brake is applied or if a brake
fault is detected. If the parking brake is not applied and
the light remains on, or if the light does not turn on, have
the light inspected by an authorized dealer.
NOTE:The light will turn on when the ignition switch
in the ON position and the parking brake is applied. This
light shows only that the parking brake is applied. It does
not show the degree of brake application. (See page 226
for more information.)
21. Vehicle Security Alarm (VSA) Indicator Light —
If Equipped
The VSA indicator Light flashes rapidly when the VSA is
arming, and slowly when the VSA is armed. (See page 15
for more information.)
22. Tire Pressure Monitoring Telltale Light — If
Equipped
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the

The selector lever is automatically locked while in the P
(Park) position. To move the selector lever out of the P
(Park) position, the brake pedal must be firmly depressed
before the shift lock will release.
Shift the selector lever to the desired position only when
the engine is idling normally and the brake pedal is
applied. Do not release the brake until ready to drive. The
vehicle may otherwise accelerate quickly when the selec-
tor lever is in D (Drive) or R (Reverse) position.
WARNING!
Unintended movement of a vehicle could injure
those in and near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, you should always
shift the vehicle into P (Park), remove the key from
the ignition, and apply the parking brake. Once the
key is removed from the ignition, the transmission
selector lever is locked in the P (Park) position,
securing the vehicle against unwanted movement.
Furthermore, you should never leave children unat-
tended inside a vehicle.
Over Temperature Mode
The transmission electronics constantly monitor the
transmission oil temperature. If the transmission exceeds
normal operating temperature, the transmission will
change the way it shifts to help control the condition.
This may result in a slightly different feeling or response
during normal operation in D (Drive) position. After the
transmission cools down, it will return to normal opera-
tion.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a brake transmission shift
interlock system (BTSI) that holds the selector lever in the
P (Park) position when the ignition switch is in the LOCK
position. To move the selector lever out of the P (Park)
position, the ignition switch must be turned to the ON
position, and the brake pedal must be depressed.

clutch is not engaged, it may seem as if the transmis-
sion is not shifting into “Overdrive” when cold. This is
considered a normal condition. Pulling the selector
lever into the “3” position will show that the transmis-
sion is able to shift into and out of “Overdrive.”
•If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
transmission fluid partially draining from the torque
converter into the transmission. This is considered a
normal condition and it will not cause damage to the
transmission. The torque converter will refill within 5
seconds of shifting from P (Park) into any other gear
position.
Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could cause damage, the
transmission automatically shifts into second gear. The
transmission remains in second gear despite the forward
gear selected. P (Park), R (Reverse), and N (Neutral) willcontinue to operate. This Reset feature allows the vehicle
to be driven to a dealer for service without damaging the
transmission.
If the problem has been momentary, the transmission can
be reset to regain all forward gears.
•Stop the vehicle and shift into P (Park).
•Turn the key to LOCK then start the engine.
•Shift into D (Drive) and resume driving.
NOTE:Even if the transmission can be reset, we
recommend that you visit a dealer at your earliest
possible convenience. Your dealer has diagnostic equip-
ment to determine if the problem could recur.
If the transmission cannot be reset, dealer service is
required.
218 STARTING AND OPERATING

Delayed Shifts in Cold Temperatures
During cold temperature operation, you may notice
delayed upshifts depending on engine and transmission
temperature as well as vehicle speed. This feature im-
proves warm up time of the engine and transmission to
achieve maximum efficiency.
Temporary Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could result in transmission
damage, the transmission will engage Limp Home Mode.
If vehicle acceleration worsens, or the transmission no
longer shifts, the transmission is most likely operating in
the Limp Home Mode. In this mode, the transmission
will remain in the current gear until the vehicle is
brought to a stop. After the vehicle has stopped, P (Park),
R (Reverse), and N (Neutral) will continue to operate.
Second gear will operate in the D (Drive) shifter position.
The Malfunction Indicator Light may be illuminated.
A reset feature is available to allow the vehicle to be
driven to a dealer for service. To reset the transmission,
use the following procedure:
1. Stop the vehicle.2. Move the selector lever to the P (Park) position.
3. Turn off the engine.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Move the selector lever to the desired range. If the
problem is no longer detected, the transmission will
return to normal operation.
NOTE:Even if the transmission can be reset, we
recommend that you visit a dealer at your earliest
possible convenience. Your dealer has diagnostic equip-
ment to determine if the problem could recur.
Have the transmission checked at your authorized dealer
as soon as possible.
If the problem has been momentary, the transmission can
be reset to regain all forward gears.
Permanent Transmission Limp Home Mode
Permanent Limp Home Mode will be activated if the
transmission enters temporary Limp Home Mode three
222 STARTING AND OPERATING

CAUTION!
•Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler tube cap (gas cap).
•A poorly fitting gas cap could let impurities into
the fuel system.
•A poorly fitting gas cap may cause the Malfunc-
tion Indicator Light to turn on.
•To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling. When the fuel
nozzle “clicks” or shuts off, the fuel tank is full.
WARNING!
•Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
•Never add fuel to the vehicle when the engine is
running.
•A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling.
NOTE:
•
Tighten the gas cap until you hear a “clicking” sound.
This is an indication that the gas cap is tightened
properly. The Malfunction Indicator Light in the in-
strument cluster may turn on if the gas cap is not
secured properly. Make sure that the gas cap is tight-
ened each time the vehicle is refueled.
•When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.

Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total
load must be limited so that you do not exceed the
GVWR.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR.
WARNING!
Because the front wheels steer the vehicle, it is
important that you do not exceed the maximum front
or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose
control of the vehicle and have an accident.
Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and the
front and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to insure that it
is not over the GVWR.
Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle’s
GVWR.
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
268 STARTING AND OPERATING

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 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.
•Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
P for Park. Always, block orchockthe trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized
(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight).
