Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain your
speed. When going downhill, you
might have to brake or shift to a
lower gear to keep your speed
down. If the brake pedal is applied,
cruise control will disengage.
Cruise Control in Manual Paddle

When the vehicle is in M (Manual
Mode) and the manual paddle shift
controls are not being used, cruise
control operates in the same
manner as D (Drive).

Mode) and the manual paddle shift
controls are being used, cruise
control operates as follows:
.If cruise control is active and a
gear is selected with the manual
paddle shift controls, the vehiclespeed is maintained in the driver
selected gear and will not
automatically upshift or
downshift the transmission while
the driver
’s gear selection is
active.
.If driving in hilly terrain, cruise
control may not be able to
maintain vehicle speed if an
upshift or downshift is not
selected by the driver. While
driving on hilly terrain and cruise
control is active with a manual
paddle shift gear selection, the
driver must select the proper
gear for the terrain or select D
(Drive) on the gear range
selector for full automatic
transmission operation.

handling, 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.
GM Accessories are designed to
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.
Also, seeAdding Equipment to the
Airbag-Equipped Vehicle on
page 3-25.Lifting the Vehicle
{Warning
Lifting a vehicle can cause an
injury. The vehicle can slip off the
jack and roll over you or other
people. You and they could be
badly injured. Find a level place
to lift your vehicle. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put an automatic transmission in P (Park) or a
manual transmission in
1 (First) or R (Reverse).
3. Turn off the engine.
To be even more certain the
vehicle will not move, put blocks
in front of and behind the wheels.
{Warning
Getting under a vehicle when it is
lifted on a jack is dangerous.
If the vehicle slips off the jack,
you could be badly injured or
killed. Never get under a vehicle
when it is supported only by
a jack.
{Warning
Raising the vehicle with the jack
improperly positioned can
damage the vehicle or the vehicle
may fall and cause injury to you
or others.
If a jack is used to lift the vehicle,
follow the instructions that came
with the jack, and be sure to use the
correct lifting points to avoid
damaging the vehicle.

Automatic Transmission
Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to the
dealer and have it repaired as soon
as possible.
The vehicle is not equipped with a
transmission fluid level dipstick.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at the dealer. Contact the
dealer for additional information or
the procedure can be found in the
service manual. To purchase a
service manual, seeService
Publications Ordering Information
on page 13-11.
{Caution
Use of the incorrect automatic
transmission fluid may damage
the vehicle, and the damage may
not be covered by the vehicle
warranty. Always use the
automatic transmission fluid listed
in Recommended Fluids and
Lubricants on page 11-12.
Change the fluid and filter at the
intervals listed in Maintenance
Schedule on page 11-2, and be sure
to use the fluid listed in
Recommended Fluids and
Lubricants on page 11-12.
Manual Transmission
Fluid
It is not necessary to check the
manual transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to the
dealer and have it repaired as soon as possible. See
Recommended
Fluids and Lubricants on page 11-12
for the proper fluid to use.
Hydraulic Clutch
It is not necessary to regularly
check clutch fluid unless you
suspect there is a leak in the
system. Adding fluid will not correct
a leak. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.
The fluid will darken over time. See
Maintenance Schedule on
page 11-2 for when to replace the
fluid.

to Use

Vehicle Care 10-35
What to Use
To add lubricant when the level is
low or to completely refill after
draining, seeRecommended Fluids
and Lubricants on page 11-12. Then
fill to within 13 mm (0.5 in) of the
bottom of the fill plug hole threads
with the required lubricant.
Starter Switch Check
{Warning
When you are doing this
inspection, the vehicle could
move suddenly. If the vehicle
moves, you or others could be
injured.
1. Before starting this check, be sure there is enough room
around the vehicle. 2. Firmly apply both the parking
brake and the regular brake.
See Electric Parking Brake on
page 9-35.
Do not use the accelerator
pedal, and be ready to turn off
the engine immediately if it
starts.
3. For automatic transmission vehicles, try to start the engine
