Dual Battery System - SEO 6A6

Your vehicle may have a dual battery system.
The two batteries are connected so that both supply
battery power to the vehicle at the same time — they are
connected in parallel. See "Battery" in your owner
manual Index for additional information on batteries.

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 are
equipped with a Tire Pressure Monitor (TPM) system.
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.
