2004 GMC Safari Owner ManualM

Vehicle Damage Warnings
Also, in this book you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice will tell you about something that can damage
your vehicle. Many times, this damage would not be
covered by your warranty, and it could be costly. But the
notice will tell you what to do to help avoid the
damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
You’ll also see warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle has components and labels that use
symbols instead of text. Symbols, used on your vehicle,
are shown along with the text describing the operation
or information relating to a specic component, control,
message, gage or indicator.
If you need help guring out a specic name of a
component, gage or indicator, reference the following
topics:
Seats and Restraint Systems in Section 1
Features and Controls in Section 2
Instrument Panel Overview in Section 3
Climate Controls in Section 3
Warning Lights, Gages and Indicators in Section 3
Audio System(s) in Section 3
Engine Compartment Overview in Section 5
iv

To fully open the rear
doors, push in on the clip
and lift the check
assembly up off the
mounting bracket.
Do this on each door. Replace the check assemblies on
the mounting brackets before closing the doors.
{CAUTION:
It can be dangerous to drive with the rear
glass open because carbon monoxide (CO)
gas can come into your vehicle. You can not
see or smell CO. It can cause
unconsciousness and even death. If you must
drive with the rear glass open or if electrical
wiring or other cable connections must pass
through the seal between the body and the
rear glass:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. SeeClimate Control
System on page 3-18.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-28.
2-12

Running Your Engine While You
Are Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier Caution under
Engine Exhaust on page 2-28.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard. See
Winter Driving on page 4-24.
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. Do not leave your vehicle when the engine
is running unless you have to. If you have left
the engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P).
Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into Park (P) on page 2-25.
If you are pulling a trailer, seeTowing a Trailer on
page 4-35.
