Driving Information
Vehicle Load Limits
The information in this section of the
supplement is 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
your owner manual Index for
additional loading information.

9-2 Driving and Operating
The following guidelines can help
you with proper loading and load
distribution when installing
additional equipment on the Tahoe
Police 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.
.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.

Using heavier suspension
components to get added durability
might not change your weight
ratings. Ask your dealer to help you
load your vehicle the right way.

Starting and
Operating
Fast Idle System
While parked with the engine idling
for an extended period, turn off the
following factory equipment if
emergency lighting and
communication equipment are
operating:
.Air Conditioner
.Fan
.Rear Window Defogger
.Factory Audio System
See “Running the Vehicle While
Parked” in the owner manual.
Engine Idle Speed - Alternator
Output
Normal idle speed for the engine is
set for 600 rpm. To increase
alternator output while the
transmission remains in P (Park) or
N (Neutral), and the electrical load
on the alternator is large enough,
the engine idle speed can rise to as
high as 800 to 1000 rpm.
Towing
Trailer Towing
The Tahoe Police Package (SEO
PPV) is not intended to tow a trailer.
The Tahoe Special Service Package
(SEO 5W4) can be equipped for
trailer towing. See “Trailer Towing”
in the owner manual for more
information.

Refer to the Tire and Loading
Information label, located on the
driver B-pillar, for information
regarding tire sizes, speed
ratings, and recommended tire
inflation pressures. See "Tire
and Loading Information Label"
under Vehicle Load Limits in the
owner manual for more
information. The Special Service
Package is not designed nor
intended for use in high‐speed
emergency vehicle operations.
Wheels
Metal hub caps are standard
with SEO PPV. These caps are
bolted to the wheels and do not
require removal when rotating or
removing the wheels. Loosening or tightening the decorative
wheel attachment nuts can be
done with the hub caps in place.
Tire Pressure Monitor
System
The Tahoe Police and Special
Service Packages may have a Tire
Pressure Monitor System (TPMS).
Sensors are mounted on each tire
and wheel assembly. Only the
Tahoe Police Package (SEO PPV)
has a TPM sensor in the full‐size
spare tire and wheel assembly. The
TPM system will not monitor or
display the spare tire's air pressure
until it is installed onto one of the
four tire/wheel positions on your
vehicle.
Once installed, the spare tire's
sensor code must be matched its
new tire/wheel position on your
vehicle. See
“Tire Pressure Monitor
System” in your owner manual
Index for information about the TPM
system.

Appearance Care
Floor Mats
{WARNING
If a floor mat is the wrong size or
is not properly installed, it can
interfere with the pedals.
Interference with the pedals can
cause unintended acceleration
and/or increased stopping
distance which can cause a crash
and injury. Make sure the floor
mat does not interfere with the
pedals.Use the following guidelines for
proper floor mat usage.
.The original equipment floor
mats were designed for the
vehicle. If the floor mats need
replacing, it is recommended
that GM certified floor mats be
purchased. Non-GM floor mats
may not fit properly and may
interfere with the pedals. Always
check that the floor mats do not
interfere with the pedals.
.Use the floor mat with the
correct side up. Do not turn
it over.
.Do not place anything on top of
the driver side floor mat.
.Use only a single floor mat on
the driver side.
.Do not place one floor mat on
top of another.
