vehIcLe Load LImIts | 9

This information is intended for those who intend to install additional equipment to the police vehicle after it has left the factory, and for those

who will be driving and loading the vehicle with passengers and/or cargo. Two labels on your vehicle show how much weight it was designed

to carry, the Tire and Loading Information label and the Certification/Tire label. These labels are attached to your vehicle and give you the

maximum load capacity, the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for your vehicle. See "Vehicle Load

Limits" in the owner manual Index for additional loading information.

The following guidelines can help you with proper loading and load distribution when installing additional equipment on the TahoePolice

Package.

WARNING

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. THIS CAN CAUSE SYSTEMS TO BREAK AND CHANGE THE WAY THE VEHICLE HANDLES.

THIS COULD CAUSE LOSS OF CONTROL AND A CRASH. OVERLOADING CAN ALSO SHORTEN THE LIFE OF THE VEHICLE.

ADDING EQUIPMENT TO YOUR VEHICLE

Before adding accessories or equipment to your police vehicle, there are some things you need to know

• The police vehicle's maximum capacity weight (payload). The weight of your police vehicle, including a full tank of fuel but without

a driver and passengers.

• The weight of items you plan on adding to your police vehicle, like roof mounted light bar(s), push bumpers, security barrier(s), rear

storage organizer, highway flares, fire extinguishers, weapons, ammunition, radios, and video equipment.

• The weight and number of passengers you intend to carry in your vehicle.

• The total weight of any additional cargo you intend to carry in your vehicle.

When planning your vehicle equipment installation remember not to exceed the Gross Vehicle Weight Rating (GVWR) or the Gross Axle Weight

Rating (GAWR) of the front or rear axles. To keep the available load weight less than the vehicle capacity weight, you may need to limit the

number of passengers you carry in your vehicle or change your choice of additional equipment.

CENTER OF GRAVITY CG

A vehicle's center of gravity is an imaginary location inside the vehicle and is a balance point for the vehicle mass as it moves down the road. The

police vehicle's center of gravity, before you add a load and passengers, is approximately midway between the center of the axles, up from the

ground to just below the front window, and between the driver and passenger. Equipment location and weight on the vehicle's center of gravity

is important to keep in mind when planning an installation. Heavy equipment should be positioned as low and as far forward in the rear load

compartment as possible. Try to mount the equipment below the bottom of the side windows. Refer to the Loading Zone chart and diagram to

help with your installation plan.

A procedure to make the necessary measurements and formulas to calculate the vehicle longitudinal, lateral and vertical position of the center

of gravity can be found in the GM Coachbuilders Manual.

Equipment required to conduct the measurements for calculating the center of gravity are:

• Weight scales of sufficient capacity to measure the vehicle weight at each wheel.

• A post type hoist or other means to safely elevate the front of the vehicle to at least an angle of 20 degrees above horizontal.

See your GM dealer to get more information about this coachbuilder procedure.

Keeping the center of gravity midway between the axles is also important to provide proper braking performance. About half the total vehicle

weight on each axle is recommended.

Weigh your vehicle after the additional equipment has been installed to determine the actual weight of your vehicle. Weigh the vehicle with a

full tank of fuel and without passengers. You may need to put a limit on how many people or other equipment you can carry inside your vehicle

after the additional equipment has been installed.
