Stowing the Crossbars
Reverse the procedure to stow the crossbars, again,
taking care to keep hand clear of pivoting joint. Crossbars
are identical and can be stowed in either rail nest. Once
the crossbars are stowed, tighten the thumb screws
completely.NOTE:
Load should always be secured to crossbars
first, with rail tie down loops used as additional securing
points if needed. Tie loops are intended as supplemen-
tary tie down points only. Do not use ratcheting mecha-
nisms with the tie loops.

CAUTION!
•Check deployed crossbars frequently and re-
tighten thumb screws as necessary.
•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 appropri-
ately.
•To prevent damage to the roof of your vehicle, DO
NOT carry any loads on the roof rack without the
crossbars deployed.
•The load should be secured and placed on top of
the crossbars, not directly on the roof. If it is
necessary to place the load on the roof, place a
blanket or other protective layer between the load
and the roof surface.(Continued)
CAUTION! (Continued)
•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 care-
fully when carrying large or heavy loads on the
roof rack. Wind forces, due to natural causes or
nearby truck traffic, can add sudden upward lift to
a load. This is especially true on large flat loads
and may result in damage to the cargo or your
vehicle.

16. Shift Lever Indicator
The Shift Lever Indicator is self-contained within the
instrument cluster. It displays the gear position of the
automatic transmission.
NOTE:
•You must apply the brakes before shifting from PARK.
•The highest available transmission gear is displayed in
the lower right corner of the Electronic Vehicle Infor-
mation Center (EVIC) whenever the Electronic Range
Select (ERS) feature is active. Use the +/- selector on
the shift lever to activate ERS. Refer to “Automatic
Transmission” in “Starting And Operating” for further
information.
17. Vehicle Security Light — If Equipped This light will flash at a fast rate for approxi-
mately 15 seconds, when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed. 18. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition
has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake
and a brake pedal pulsation may be felt during each stop.

WARNING! (Continued)
•Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, always apply the
parking brake, shift the transmission into PARK,
and remove the key fob. Once the key fob is
removed, the shift lever is locked in the PARK
position, securing the vehicle against unwanted
movement. Furthermore, you should never leave
unattended children inside a vehicle.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the shift lever to be placed in PARK
before the ignition switch can be turned to the LOCK/
OFF position. The key fob can only be removed from the
ignition when the ignition is in the LOCK/OFF position,
and once removed, the shift lever is locked in PARK.This system prevents the key fob from being removed
unless the shift lever is in PARK.
NOTE:
If a malfunction occurs, the system will trap the
key fob in the ignition cylinder to warn you that this
safety feature is inoperable. The engine can be started
and stopped but the key fob cannot be removed until you
obtain service.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in the
PARK position unless the brakes are applied. To move
the shift lever out of the PARK position, the ignition
switch must be turned to the ON/RUN position (engine
running or not) and the brake pedal must be pressed.
424 STARTING AND OPERATING

WARNING! (Continued)
•Your vehicle could move and injure you and others
if it is not completely in PARK. Check by trying to
move the shift lever rearward (with the brake
pedal released) after you have placed it in PARK.
Make sure the transmission is in PARK before
leaving the vehicle.
•It is dangerous to move the shift lever out of PARK
or NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing the
brake pedal, the vehicle could accelerate quickly
forward or in reverse. You could lose control of the
vehicle and hit someone or something. Only shift
into gear when the engine is idling normally and
your foot is firmly pressing the brake pedal.(Continued)

428 STARTING AND OPERATING

2. Shift the transmission into PARK.
3. Turn the engine OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
NOTE:Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.
If the transmission cannot be reset, authorized dealer
service is required.Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the shift
lever is in the DRIVE position. For example, if you shift
the transmission into 3 (third gear), the transmission will
never shift above third gear, but will shift down into
second and first gear normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the shift lever is in the DRIVE
position, the transmission will operate automatically,
shifting between all available gears. Tapping the shift
lever to the left (-) will activate ERS mode, display the
current gear in the instrument cluster, and maintain that
gear as the top available gear. Once in ERS mode, tapping
the shift lever to the left (-) or right (+) will change the top
available gear.

Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
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 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 ensure 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
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.
494 STARTING AND OPERATING

WARNING! (Continued)
•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 a collision.
•When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or dam-
age to brakes, axle, engine, transmission, steering,
suspension, 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.(Continued)
WARNING! (Continued)
•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 PARK. Always, block or chock
the 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. Trailer tongue weight rating for that trailer
hitch. (This requirement may limit the ability to
always achieve the 10% to 15% range of trailer
tongue weight as a percentage of total trailer
weight.)
