Driving and Operating 9-17
The instruments and audio systems
will operate as they do in ON/RUN,
but the vehicle will not be able to be
driven. The engine will not start in
Service Only Mode. Push the button
again to turn the vehicle off.
Starting the Engine
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
engine when the vehicle is already
moving, use N (Neutral) only.
Notice:Do not try to shift to
P (Park) if the vehicle is moving.
If you do, you could damage the
transmission. Shift to P (Park)
only when the vehicle is stopped.
Notice: If you add electrical parts
or accessories, you could change
the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.
See Add-On Electrical Equipment
on page 9‑65. Starting Procedure
1. With the keyless access system,
the transmitter must be in the
vehicle. Put your foot on the
brake pedal and push the
START button. When the engine
begins cranking, let go of the
button.
The idle speed will go down as
the engine gets warm. Do not
race the engine immediately
after starting it. Operate the
engine and transmission gently
to allow the oil to warm up and
lubricate all moving parts.
If the transmitter is not in the
vehicle or something is
interfering with the transmitter,
the Driver Information Center
(DIC) will display a message.
See Key and Lock Messages on
page 5‑38.
If the battery in the Remote
Keyless Entry (RKE) transmitter
needs replacing, the DIC will
display a message. The vehicle
can still be driven. See “Startingthe Vehicle with a Low
Transmitter Battery”
inRemote
Keyless Entry (RKE) System
Operation on page 2‑3.
The vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. If the START
button is pressed, and then
released when the engine
begins cranking, the engine will
continue cranking for a few
seconds or until the vehicle
starts. If the engine does not
start and the button is pressed
for many seconds, cranking will
be stopped after 15 seconds to
prevent cranking motor damage.
To prevent gear damage, this
system also prevents cranking if
the engine is already running.
Engine cranking can be stopped
by pressing the START button a
second time.
Notice: Cranking the engine for
long periods of time, by pressing
the START button immediately

Accessories and
Modifications
Adding non‐dealer accessories or
making modifications to the vehicle
can affect vehicle performance and
safety, including such things as
airbags, braking, stability, ride andhandling, emissions systems,
aerodynamics, durability, and
electronic systems like antilock
brakes, traction control, and stability
control. These accessories or
modifications could even cause
malfunction or damage not covered
by the vehicle warranty.
Damage to vehicle components
resulting from modifications or the
installation or use of non‐GM
certified parts, including control
module or software modifications, is
not covered under the terms of the
vehicle warranty and may affect
remaining warranty coverage for
affected parts.

complement and function with other
systems on the vehicle. See your
dealer to accessorize the vehicle
using genuine GM Accessories
installed by a dealer technician.

Doing Your Own
Service Work
{WARNING
It can be dangerous to work on
your vehicle if you do not have
the proper knowledge, service
manual, tools, or parts. Always
follow owner manual procedures
and consult the service manual

service work.
If doing some of your own service
work, use the proper service
manual. It tells you much more
about how to service the vehicle
than this manual can. To order the
proper service manual, see Service
Publications Ordering Information
on page 13‑11.
