If  you have the optional luggage carrier,  you can load 
things  on  top of your  vehicle. 
The  luggage carrier  has slats and  side rails attached  to 
the  roof,  and crossrails  which can be moved toward the 
front or the rear  in the side rails 
to help  secure  cargo. Tie 
the  load  to the  side rails  or  side rail  supports. 
NOTICE: 
Loading  cargo  that  weighs  more  than 200 lbs. 
(90.6 kg) on  the  luggage  carrier  may  damage 
your  vehicle.  When 
you carry  large  things,  never 
let  them  hang  over  the  rear  or  the  sides 
of your 
vehicle.  Load  your  cargo 
so that it rests  on  the 
slats  and  does  not  scratch  or  damage  the  vehicle. 
Put  the  cargo  against  the  side  rails  and  fasten 
it 
securely  to  the  luggage  carrier. 
Don’t exceed  the  maximum  vehicle capacity when 
loading  your vehicle.  For more information  on vehicle 
capacity  and loading,  see “Loading  Your  Vehicle” 
in 
the Index.  To 
prevent  damage  or  loss of cargo as  you’re  driving, 
check  now and then  to make sure  the luggage  carrier  and 
cargo are still securely fastened. 
Be sure the  cargo is properly  loaded. 
If small heavy  objects are placed  on the roof, place 
the load in the area over the  rear wheels  (behind 
the 
rear  side  door  on  Suburbans).  If you  need to,  cut  a 
piece  of 3/8  inch  plywood to fit  inside the crossrails 
and side rails to spread the  load, If plywood  is  used, 
tie  it to  the  side  rail supports. 
Tie the load to the crossrails  or the  side  rail supports. 
Use  the crossrails only  to keep the  load  from  sliding. 
0 If  you need to carry  long items, move the  crossrails 
as  far  apart as they will go. Tie  the load  to  the 
crossrails and  the  side rails or  side  rail supports.  Also 
tie the load to  the bumpers.  Do  not tie the load 
so 
tightly that the crossrails  or side rails  are  damaged. 
0 After moving the  crossrails, be sure  to  tighten  all the 
slider  screws. 
For the purpose  of wind noise reduction,  locate 
the front  crossrail  approximately 
18-24 inches 
(46 cm to 58 cm) rearward  of the  front  supports.

With the anti-lock  brake 
system, this  light will come 
ANTI - 
LOCK 
on when  you start your 
engine  and may stay  on  for 
several  seconds. 
That’s normal. 
Engine  Coolant  Temperature  Gage 
This gage shows  the engine 
coolant temperature. 
If  the  light  stays on, or comes  on  when you’re  driving, 
your  vehicle  needs service.  If the  regular  brake  system 
warning  light  isn’t on, you still have brakes, but  you 
don’t  have anti-lock  brakes.  If the  regular  brake  system 
warning  light is also  on,  you don’t have anti-lock  brakes 
and  there’s  a problem with your  regular brakes.  See 
“Brake  System  Warning Light”  earlier in this section. 
The  anti-lock  brake  system warning  light should  come 
on  briefly  when you turn the  ignition key to 
RUN. If the 
light  doesn’t  come  on  then,  have it  fixed 
so it will be 
ready  to warn  you  if  there  is  a problem. 
It also  provides  an indicator  of how  hard  your vehicle  is 
working. During  a majority  of the operation,  the gage 
will read 
2 10 OF ( 100 ” C) or  less.  If  you  are pulling  a 
load  or  going  up  hills, it is normal for  the temperature 
to 
fluctuate and approach the 260 OF( 160” C) mark.  If  the 
gage  reaches the 
260”F( 160°C) mark,  it indicates that 
the cooling system 
is working  beyond its capacity. 
In  “Problems  on  the Road,” this  manual  shows  what  to 
do.  See  “Engine Overheating”  in  the Index.

When the ignition  is  on, the 
fuel  gage  tells you about 
how  much  fuel  you have 
left in your tank. 
The  gage  will first  indicate 
EMPTY (E) before you  are 
out 
of fuel,  and you  should  get more  fuel  as  soon 
as possible. 
Listed 
are four  situations  you  may experience  with your 
fuel  gage: 
At  the  gas  station, the  fuel  pump shuts off before  the 
gage  reads  FULL  (F). 
It takes a little more  or less fuel to fill  up  than  the 
fuel  gage  indicated. For example, the gage  may  have 
indicated the tank  was  half full, but 
it actually  took  a 
little more  or less  than  half the tank’s  capacity  to fill 
the  tank. 
The gage  moves  a little when  you  turn a corner or 
speed up. 
The  gage doesn’t go back  to EMPTY (E) when  you 
turn  off the ignition. 
None 
of these indicate a problem  with  the fuel gage.

The Certificatiomire label is found on the rear  edge of 
the driver's  door.  The 
label shows the size  of  your original  tires  and  the 
inflation pressures  needed to obtain  the gross  weight 
capacity  of your vehicle. This is called  the  GVWR 
(Gross  Vehicle  Weight  Rating). The GVWR includes  the 
weight 
of the vehicle,  all occupants, fuel  and cargo. 
The  Certificatioflire  label also tells you 
the maximum 
weights for the  front and rear axles, called Gross  Axle 
Weight  Rating (GAWR).  To find out  the actual loads on 
your front and  rear axles,  you  need  to go  to a  weigh 
station  and weigh your vehicle.  Your dealer  can  help 
you  with  this. Be sure  to spread out  your  load equally on 
both sides 
of the centerline. 
Never  exceed  the GVWR  for your  vehicle,  or the 
GAWR  for  either  the front or rear  axle. 
And,  if 
you do have  a heavy  load, you should spread 
it  out.

There are  many different laws, including speed limit 
restrictions, having to  do with trailering.  Make  sure 
your  rig  will  be  legal, 
not only  where  you live but 
also where you’ll  be driving.  A  good  source  for this 
information can  be state  or  provincial police. 
Consider using  a sway  control  if your trailer will 
weigh  less than  the capacity  stamped  on your  step 
bumper.  You should  always  use a sway control  if 
your  trailer  will  weigh  more than the capacity 
stamped on  your  step bumper. You can ask  a hitch 
dealer  about  sway  controls. 
Don’t  tow  a trailer  at all  during  the first 
500 miles 
(800 km) your new vehicle is  driven. Your engine, 
axle or other  parts could be  damaged. 
Then, during  the first 
500 miles (800 km) that  you 
tow  a trailer,  don’t  drive over 
50 mph (80 kmh) and 
don’t  make  starts at 
full throttle.  This  helps your 
engine  and other parts  of your vehicle wear  in  at the 
heavier  loads. 
If  you  have  an automatic transmission,  you can tow 
in  OVERDRIVE 
(@). You  may want  to shift the 
transmission to THIRD 
(3) or,  if necessary,  a  lower 
gear  selection 
if the transmission  shifts  too often 
(e.g., under  heavy loads and/or  hilly conditions).  Three  important 
considerations have  to  do with weight: 
the weight  of the trailer, 
0 the weight of the trailer tongue 
0 and the weight  on your vehicle’s  tires. 
Weight of the  Trailer 
How heavy can  a trailer safely  be? 
It  depends  on  how 
you plan to use your  rig.  For 
example,  speed, altitude, road grades,  outside 
temperature  and how much your vehicle  is used  to pull  a 
trailer  are all important. And,  it can  also  depend  on  any 
special  equipment  that you have  on your  vehicle. 
Use  the  following  chart  to determine  how  much  your  vehicle 
can  weigh,  based  upon  your  vehicle  model  and options. 
Maximum  trailer weight  is calculated  assuming  the 
driver and 
one passenger  are  in the tow  vehicle  and  it 
has all the required trailering  equipment.  The  weight 
of 
additional optional equipment, passengers and  cargo  in 
the tow vehicle must  be subtracted  from the  maximum 
trailer weight. 
Above  the 
2,000 lbs. (908 kg) trailer rating,  the  engine 
oil  cooler  is  required on 
C/K-1500 and C/K-2500 
models. Refer  to the Trailering  Guide  for oil 
cooler  recommendations.

Weight of the  Trailer  Tongue 
The  tongue  load (A) of any  trailer  is  an important 
weight 
to measure  because it affects  the total  or gross 
weight  of your  vehicle.  The  Gross  Vehicle  Weight 
(GVW)  includes  the curb  weight  of the vehicle, any 
cargo 
you may  carry in it,  and the people  who will be 
riding  in  the vehicle. And  if  you  will tow a trailer,  you 
must  add the tongue  load  to the  GVW  because  your 
vehicle  will be carrying  that weight,  too. See  “Loading 
Your  Vehicle”  in the  Index  for more  information  about 
your vehicle’s maximum  load capacity. 
B 
If you’re  using  a  weight-carrying  hitch,  the trailer 
tongue  (A) should  weigh 
10 percent  of the  total  loaded 
trailer weight 
(B). If  you’re  using a weight-distributing 
hitch, the  trailer  tongue 
(A) should weigh 12 percent  of 
the total  loaded  trailer  weight 
(B). 
After you’ve  loaded  your trailer,  weigh  the  trailer  and 
then the tongue,  separately,  to see if 
the weights  are 
proper.  If  they aren’t,  you  may  be able to get  them  right 
simply  by moving  some items around in  the  trailer.   

Downloaded from www.Manualslib.com manuals search engine Total  Weight on Your Vehicle’s  Tires 
Be sure  your  vehicle’s  tires are inflated to the upper 
limit  for cold tires.  You’ll find these numbers on the 
Certification label at  the rear  edge  of the driver’s  door  or 
see  “Tire  Loading’’  in the  Index.  Then be sure  you don’t 
go over  the GVW limit for your vehicle, including  the 
weight  of  the  trailer tongue. 
Hitches 
It’s important to have  the correct hitch  equipment. 
Crosswinds, large trucks  going by and rough roads  are 
a 
few  reasons  why  you’ll need the right hitch. Here  are 
some  rules to  follow: 
If  you use a step-bumper hitch, your bumper  could 
be  damaged in sharp turns.  Make sure you  have 
ample  room when turning  to avoid contact between 
the  trailer  and the bumper. 
If you’ll  be  pulling a trailer that,  when loaded, will 
weigh  more than  the capacity stamped on your  step 
bumper,  be sure to  use a properly mounted, 
weight-distributing hitch and sway control  of the 
proper size.  This equipment is  very important  for 
proper  vehicle loading and good handling when 
you’re  driving. 
Will  you  have to  make  any holes  in the body of your 
vehicle when  you install a trailer  hitch? 
If  you  do, then be  sure to seal the  holes  later  when 
you  remove  the hitch.  If  you don’t seal  them,  deadly 
carbon monoxide (CO)  from your exhaust  can  get 
into  your vehicle (see “Carbon  Monoxide” 
in the 
Index). Dirt and water  can, too. 
Safety Chains 
You should always attach chains between your vehicle 
and your trailer. Cross the safety  chains  under  the  tongue 
of the trailer so that the tongue will not  drop  to the  road 
if 
it becomes separated  from the hitch.  Instructions 
about safety chains  may be provided 
by the  hitch 
manufacturer  or 
by the trailer manufacturer. Follow  the 
manufacturer’s recommendation  for  attaching  safety 
chains  and do not attach them  to the bumper.  Always 
leave  just enough slack 
so you can  turn  with your  rig. 
And, never allow safety  chains  to  drag 
on the  ground.

Downloaded from www.Manualslib.com manuals search engine When to Add Oil 
If the oil is  at or  below  the ADD mark, then you’ll need 
to  add  at  least one quart  of oil.  But you must use the 
right kind. This  part explains what kind 
of oil to  use.  For 
crankcase  capacity, see “Capacities and Specifications” 
in  the  Index. 
NOTICE: 
Don’t  add  too  much  oil. If your  engine  has so 
much  oil  that  the  oil  level  gets  above  the  upper 
mark  that 
shows the  proper  operating  range, 
your  engine  could  be  damaged. 
The engine oil fill cap on the “VORTEC” 5700 is 
located on the driver’s side  engine valve cover.  The 
engine oil fill  cap on the  “VORTEC” 
7400 is located  on 
the front 
of the  engine, near the radiator. 
Be sure  to fill  it enough  to put the  level somewhere in 
the  proper operating range. Push the dipstick all the  way 
back  in  when  you’re through. 
What Kind of Oil to Use 
Oils recommended  for your vehicle  can  be identified by 
looking  for  the “Starburst” symbol.  This  symbol 
indicates that the  oil has been certified  by the American 
Petroleum  Institute (API). 
Do not use any oil which 
does  not carry this  Starburst symbol. 
If  you  change  your  own  oil, 
be sure you  use  oil  that  has 
the  Starburst  symbol 
on the 
front  of the  oil  container. 
If  you  have  your  oil  changed for you, be  sure  the  oil  put 
into  your  engine  is  American Petroleum  Institute 
certified  for  gasoline  engines. 
You should also  use  the proper viscosity  oil  for  your 
vehicle,  as shown in the following  chart:
