will choose to focus on the changes to both the Silverado's and Sierra's
exteriors, much of GM's mid-cycle enhancement is happening inside the
trucks and under the skin. And it's quite a group of welcome and advanced
space in both trucks is significantly and similarly upgraded to make it
more convenient, comfortable and safe for drivers and passenger.
dashboards on the Sierra and Silverado accommodate a new vehicle information
center, conveniently housed at the bottom of the instrument panel. The
information center provides data on up to 36 separate system functions
Denali gets its own distinct instrument cluster for 2003. Its white needles
and numbers are framed within a black background. At night the gauges
glow with blue backlighting. Standard Silverado and Sierra pickups get
a black background with orange pointers and white backlighting at night.
system has been completely overhauled to now include manual or electronic
operated dual-zone and tri-zone air conditioning depending on cab configuration.
This is a direct benefit of the trucks' new electrical architecture (more
on that later) and, according to GM Full Size Truck Chief Engineer Terry
Woychowski, it provides a range of up to 30 degrees difference in temperature
GM has also
made significant additions and enhancements to trucks' "infotainment"
systems. All new Series 175 radios are equipped to pick up XM radio, digitally
broadcast by satellite and available nationwide for around $10 per month.
On the premium end of the audio spectrum, GM has teamed up with Bose Audio
Systems to provide a custom-tailored stereo system. Rear passengers in
crew cab pickups can watch DVD movies on an optional 7-inch flip down
A new and
vastly improved steering wheel for 2003 obsoletes the old wheel which
had extremely hard to reach radio controls. Easy to find, thumb-friendly
buttons provide the driver with redundant control over the driver information

seats with more contours and easier to reach seat controls are available
across the board for 2003. Silverado and Sierra pickups with bucket seats

risk on GM's part with the 2003 freshening means lower risk for driver
and passengers in the event of an accident. Passive and active safety
systems have been significantly upgraded to include a passenger sensing
system that can automatically deactivate the passenger-side front airbag
based on that person's size and weight. Dual stage air bags are tied to
sensors that determine in 15ms how severe a crash is and whether to deploy
the airbag full or de-powered. And if an occupant is sitting in the first
third of the distance of seat travel to the steering wheel or dash, the
safety systems will deploy a low airbag for added protection.
