WARNING!
Do not downshift for additional engine braking on
a slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision
or personal injury.
Transmission Limp Home Mode
Transmission function is electronically monitored for
abnormal conditions. If a condition is detected that
could result in transmission damage, Transmission
Limp Home Mode is activated. In this mode, the
transmission remains in fourth gear regardless of which
forward gear is selected. PARK, REVERSE, and NEU-
TRAL will continue to operate. The Malfunction Indi-
cator Light (MIL) may be illuminated. Limp Home
Mode allows the vehicle to be driven to an authorized
dealer for service without damaging the transmission.In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing
the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Cycle the ignition to the STOP/OFF position.
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 nor-
mal operation.
NOTE: Even if the transmission can be reset, we
recommend 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.

components sometimes specified by purchasers for
increased durability does not necessarily increase the
vehicle’s GVWR.
Tire Size
The tire size on the Vehicle Certification Label repre-
sents the actual tire size on your vehicle. Replacement
tires must be equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle
for all loading conditions up to full GAWR.
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.
Loading
The actual total weight and the weight of the front and
rear of your vehicle at the ground can best be deter-
mined by weighing it when it is loaded and ready for
operation.
The entire vehicle should first be weighed on a com-
mercial scale to insure that the GVWR has not been
exceeded. The weight on the front and rear of the
vehicle should then be determined separately to be sure
that the load is properly distributed over the front and
rear axle. Weighing the vehicle may show that the
GAWR of either the front or rear axles has been ex-
ceeded but the total load is within the specified GVWR.
If so, weight must be shifted from front to rear or rear to
front as appropriate until the specified weight limita-
tions are met. Store the heavier items down low and be
sure that the weight is distributed equally. Stow all
loose items securely before driving.
Improper weight distributions can have an adverse
effect on the way your vehicle steers and handles and
the way the brakes operate.

STARTING AND OPERATING 269

Consider the following items when computing the
weight on the rear axle of the vehicle:
•The tongue weight of the trailer.
• The weight of any other type of cargo or equipment
put in or on your vehicle.
• The weight of the driver and all passengers.
NOTE: Remember that everything put into or on the
trailer adds to the load on your vehicle. Also, additional
factory-installed options or dealer-installed options
must be considered as part of the total load on your
vehicle. Refer to the “Tire And Loading Information”
placard for the maximum combined weight of occu-
pants and cargo for your vehicle.
Towing Requirements
To promote proper break-in of your new vehicle drive-
train components, the following guidelines are recom-
mended:
WARNING!
Improper towing can lead to a collision. Follow
these guidelines to make your trailer towing as safe
as possible:
• Make certain that the load is secured in the trailer
and that 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 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
damage 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.
• Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on
the tow vehicle. Put the tow vehicle transmission
