2008 CHEVROLET TAHOE driver seat adjustment

Shoulder Belt Height Adjuster
Your vehicle has a shoulder belt height adjuster for
the driver and right front passenger position.
Adjust the height so that the shoulder portion of the belt
is centered on your shoulder. The belt should be away
from your face and neck, but not falling off your shoulder.
Improper shoulder belt height adjustment could reduce
the effectiveness of the safety belt in a crash.
To move it down, squeeze
the buttons (A) on the sides
of the height adjuster and
move the height adjuster
to the desired position.
You can move the adjuster up just by pushing up on
the shoulder belt guide.
After you move the adjuster to where you want it,
try to move it down without squeezing the buttons to
make sure it has locked into position.
Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for front
outboard occupants. Although you cannot see them,
they are part of the safety belt assembly. They can
help tighten the safety belts during the early stages of a
moderate to severe frontal, near frontal, or rear crash
if the threshold conditions for pretensioner activation
are met. And, if your vehicle has side impact airbags,
safety belt pretensioners can help tighten the safety
belts in a side crash or a rollover event.
Pretensioners work only once. If they activate in a
crash, you will need to get new ones, and probably other
new parts for your safety belt system. SeeReplacing
Restraint System Parts After a Crash on page 1-93.
Rear Safety Belt Comfort Guides
Rear shoulder belt comfort guides may provide added
safety belt comfort for older children who have outgrown
booster seats and for some adults. When installed on
a shoulder belt, the comfort guide positions the belt
away from the neck and head.

Adjustable Throttle and Brake Pedal
On vehicles with this feature, you can change the
position of the throttle and brake pedals.
This feature is designed for shorter drivers, since the
pedals cannot move farther away from the standard
position, but can move toward the driver for better
pedal reach.
No adjustment to the pedals can be made when
the vehicle is in REVERSE (R) or while using the
cruise control.
The switch used to adjust
the pedals is located
on the instrument panel
below the climate control
system.
Press the arrow at the bottom of the switch to move the
pedals closer to your body. Press the arrow at the top of
the switch to move the pedals away from your body.Before you start driving, fully press the brake pedal to
conrm the adjustment is right for you. While driving,
make only small adjustments.
Your vehicle may have a memory function which lets
pedal settings be saved and recalled. SeeMemory Seat,
Mirrors, and Pedals on page 1-6for more information.
Engine Coolant Heater
The engine coolant heater, if available, can help in
cold weather conditions at or below 0°F (−18°C)
for easier starting and better fuel economy during
engine warm-up. Plug in the coolant heater at least
four hours before starting your vehicle. An internal
thermostat in the plug-end of the cord may exist
which will prevent engine coolant heater operation
at temperatures above 0°F (−18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located on the driver’s side of the
engine compartment, near the power steering
uid reservoir.
3. Plug the cord into a normal, grounded 110-volt
AC outlet.

Using the Auxiliary Input Jack
The radio system has an auxiliary input jack located on
the lower right side of the faceplate. This is not an
audio output; do not plug the headphone set into the
front auxiliary input jack. An external audio device such
as an iPod, laptop computer, MP3 player, CD player,
or cassette tape player, etc. can be connected to
the auxiliary input jack for use as another audio source.
Drivers are encouraged to set up any auxiliary device
while the vehicle is in PARK (P). SeeDefensive Driving
on page 4-2for more information on driver distraction.
To use a portable audio player, connect a 3.5 mm
(1/8 inch) cable to the radio’s front auxiliary input jack.
When a device is connected, press the radio CD/AUX
button to begin playing audio from the device over
the vehicle speakers.
For optimal sound quality, increase the portable audio
device’s volume to the loudest level.
It is always best to power the portable audio device
through its own battery while playing.
O(Power/Volume):Turn clockwise or
counterclockwise to increase or decrease the
volume of the portable player. Additional volume
adjustments might have to be made from the portable
device if the volume is not loud or soft enough.BAND:Press to listen to the radio when a portable
audio device is playing. The portable audio device also
continues to play.
CD/AUX (CD/Auxiliary):Press to play a CD when a
portable audio device is playing. Press again and
the system begins playing audio from the connected
portable audio player. If a portable audio player is
not connected, “No Input Device Found” displays.
DVD/CD AUX (CD/Auxiliary):Press this button to cycle
through DVD, CD, or Auxiliary when listening to the
radio. The DVD/CD text label and a message showing
track or chapter number displays when a disc is in
either slot. Press this button again and the system
automatically searches for an auxiliary input device,
such as a portable audio player. If a portable audio
player is not connected, “No Aux Input Device” displays.
If a disc is in both the DVD slot and the CD slot the
DVD/CD AUX button cycles between the two sources
and does not indicate “No Aux Input Device”. If a
front auxiliary device is connected, the DVD/CD AUX
button cycles through all available options, such
as: DVD slot, CD slot, Front Auxiliary, and Rear Auxiliary
(if available). See “Using the Auxiliary Input Jack(s)”
later in this section, or “Audio/Video (A/V) Jacks” under,
Rear Seat Entertainment (RSE) System on page 3-105
for more information.

What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. SeeRecommended Fluids
and Lubricants on page 6-13.
Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim of the headlamps have been preset at
the factory and should need no further adjustment.
However, if the vehicle is damaged in a crash, the aim
of the headlamps can be affected and adjustment
can be necessary.
If oncoming vehicles ash their high beams at you, this
can mean the vertical aim of your headlamps needs
to be adjusted.
It is recommended that the vehicle is taken to your
dealer/retailer for service if the headlamps need to
be adjusted. It is possible however, to re-aim the
headlamps as described.The vehicle should:
Be placed so the headlamps are 25 ft. (7.6 m) from
a light colored wall.
Have all four tires on a level surface which is level
all the way to the wall.
Be placed so it is perpendicular to the wall.
Not have any snow, ice, or mud on it.
Be fully assembled and all other work stopped while
headlamp aiming is being performed.
Be normally loaded with a full tank of fuel and one
person or 160 lbs (75 kg) sitting on the driver seat.
Have tires properly inated.
Have the spare tire is in its proper location in the
vehicle.
Headlamp aiming is done with the vehicle’s low-beam
headlamps. The high-beam headlamps will be correctly
aimed if the low-beam headlamps are aimed properly.
