Vehicles with towing
mirrors can be adjusted
manually for a clear view of
the objects behind you.
Manually fold the mirrors inward to prevent damage
when going through an automatic car wash. To fold, pull
the mirror toward the vehicle. Push the mirror outward,
to return it to the original position.
Interior Mirror
Hold the inside rearview mirror in the center to move it

If the vehicle has the 4.8L V8 engine (VIN Code A), the
5.3L V8 engine (VIN Code 4), or the 6.0L V8 engine
(VIN Code G) and the N15 flexible fuel option, you can
use either unleaded gasoline or ethanol fuel containing
up to 85% ethanol (E85). SeeFuel on page 6-5.In
all other engines, use only the unleaded gasoline
described underGasoline Octane on page 6-6.
Vehicles that have the 4.8L V8 engine (VIN Code A),
the 5.3L V8 engine (VIN Code 4), or the 6.0L V8 engine

yellow fuel cap and can use 85% ethanol fuel (E85). See
Fuel E85 (85% Ethanol) on page 6-8.
Driving for Better Fuel Economy
Driving habits can affect fuel mileage. Here are some
driving tips to get the best fuel economy possible.
•Avoid fast starts and accelerate smoothly.
•Brake gradually and avoid abrupt stops.
•Avoid idling the engine for long periods of time.
•When road and weather conditions are appropriate,
use cruise control, if equipped.
•Always follow posted speed limits or drive more
slowly when conditions require.
•Keep vehicle tires properly inflated.
•Combine several trips into a single trip.
•Replace the vehicle’s tires with the same TPC Spec
number molded into the tire’s sidewall near the size.
•Follow recommended scheduled maintenance.

A thick layer of additional material, such as a blanket or
cushion, or aftermarket equipment such as seat
covers, seat heaters, and seat massagers can affect
how well the passenger sensing system operates.
We recommend that you not use seat covers or other
aftermarket equipment except when approved by GM for
your specific vehicle. SeeAdding Equipment to Your
Airbag-Equipped Vehicle on page 2-78for more
information about modifications that can affect how the
system operates.
The on indicator may be lit if an object, such as a
briefcase, handbag, grocery bag, laptop or other
electronic device, is put on an unoccupied seat. If this is
not desired remove the object from the seat.
{WARNING:
Stowing of articles under the passenger seat or
between the passenger seat cushion and seatback
may interfere with the proper operation of the
passenger sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.
There are parts of the airbag system in several places
around the vehicle. Your dealer/retailer and the
service manual have information about servicing the
vehicle and the airbag system. To purchase a service
manual, seeService Publications Ordering Information
on page 8-15.
{WARNING:
For up to 10 seconds after the ignition is turned off
and the battery is disconnected, an airbag can still
inflate during improper service. You can be injured
if you are close to an airbag when it inflates. Avoid
yellow connectors. They are probably part of the
airbag system. Be sure to follow proper service
procedures, and make sure the person performing
work for you is qualified to do so.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:The vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Keep your speed at 55 mph (88 km/h) or less for
the rst 500 miles (805 km).
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake or slow the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time the new brake
linings are not yet broken in. Hard stops
with new linings can mean premature wear and
earlier replacement. Follow this breaking-in
guideline every time you get new brake linings.
Do not tow a trailer during break-in. SeeTowing
a Trailer on page 5-26for the trailer towing
capabilities of the vehicle and more information.
Following break-in, engine speed and load can
be gradually increased.
Ignition Positions
The ignition switch has
four different positions.
To shift out of P (Park), the ignition must be in ON/RUN
and the regular brake pedal applied.
A (LOCK/OFF):This position locks the ignition and
transmission. You will only be able to remove the key
when the ignition is turned to LOCK/OFF.
Notice:Using a tool to force the key to turn in
the ignition could cause damage to the switch or
break the key. Use the correct key, make sure it
is all the way in, and turn it only with your hand.
If the key cannot be turned by hand, see your
dealer/retailer.

{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the 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 the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). SeeShifting Into
Park on page 3-36. If you are pulling a trailer, see
Towing a Trailer on page 5-26.
R (Reverse):Use this gear to back up.
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.To rock the vehicle back and forth to get out of snow,
ice, or sand without damaging the transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 5-16.
N (Neutral):In this position, the engine does not
connect with the wheels. To restart when you are
already moving, use N (Neutral) only. Also, use
N (Neutral) when the vehicle is being towed.
{WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.
Notice:Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage
the transmission. The repairs would not be covered
by the vehicle warranty. Be sure the engine is
not running at high speed when shifting the vehicle.
