Towing Equipment
Hitches
Use the correct hitch equipment.
See your dealer/retailer or a
hitch dealer for assistance.
•The rear bumper on the vehicle
is not intended for hitches.
Do not attach rental hitches
or other bumper-type hitches to
it. Use only a frame-mounted
hitch that does not attach to
the bumper.
•Will any holes be made in the
body of the vehicle when the
trailer hitch is installed? If there
are, seal the holes when the hitch
is removed. If the holes are not
sealed, dirt, water, and deadly
carbon monoxide (CO) from the
exhaust can get into the vehicle.
SeeEngine Exhaust on
page 8-25.
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the
safety chains under the tongue of
the trailer to help prevent the tongue
from contacting the road if it
becomes separated from the hitch.
Leave enough slack so the rig can
turn. Never allow safety chains to
drag on the ground.
Trailer Brakes
Does the trailer have its own
brakes? Be sure to read and follow
the instructions for the trailer brakes
so they are installed, adjusted and
maintained properly.
Because the vehicle has antilock
brakes, do not tap into the vehicle’s
brake system. If this is done,
both brake systems will not work
well, or at all.
Conversions and
Add-Ons
Add-On Electrical
Equipment
Notice:Do not add anything
electrical to the vehicle unless you
check with your dealer/retailer
rst. Some electrical equipment
can damage the vehicle and the
damage would not be covered
by the vehicle’s warranty. Some
add-on electrical equipment can
keep other components from
working as they should.
Add-on equipment can drain the
vehicle battery, even if the vehicle
is not operating.
The vehicle has an airbag system.
Before attempting to add anything
electrical to the vehicle, see
Servicing the Airbag-Equipped
Vehicle on page 2-32andAdding

California Perchlorate
Materials Requirements
Certain types of automotive
applications, such as airbag
initiators, seat belt pretensioners,
and lithium batteries contained in
remote keyless transmitters, may
contain perchlorate materials.
Special handling may be necessary.
For additional information, see
www.dtsc.ca.gov/hazardouswaste/
perchlorate.
Accessories and
Modi cations
Adding non-dealer/non-retailer
accessories to the vehicle can affect
vehicle performance and safety,
including such things as airbags,
braking, stability, ride and handling,
emissions systems, aerodynamics,
durability, and electronic systems
like antilock brakes, traction control,
and stability control. Some of these
accessories could even cause
malfunction or damage not covered
by the vehicle warranty.
Damage to vehicle components
resulting from the installation or use
of non-GM certified parts, including
control module modifications, are
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. Your GM
dealer/retailer can accessorize
the vehicle using genuine GM
Accessories. When you go to your
GM dealer/retailer and ask for GM
Accessories, you will know that
GM-trained and supported service
technicians will perform the work
using genuine GM Accessories.

Vehicle Care 9-9
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 your dealer/
retailer service department and
have it repaired as soon as possible.
SeeRecommended Fluids and
Lubricants on page 10-7for the
proper fluid to use.
Hydraulic Clutch
It is not necessary to regularly
check brake/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.
When to Check and What
to Use
The brake/hydraulic clutch fluid
reservoir cap has this symbol
on it. The common hydraulic clutch
and brake master cylinder fluid
reservoir is filled with DOT 3 brake
fluid as indicated on the reservoir
cap. SeeEngine Compartment
Overview on page 9-6for reservoir
location.
How to Check and Add Fluid
Visually check the brake/clutch
fluid reservoir to make sure the
fluid level is at the MIN (minimum)
line on the side of the reservoir.
The brake/hydraulic clutch fluid
system should be closed and
sealed.
Do not remove the cap to check
the fluid level or to top-off the fluid
level. Remove the cap only when
necessary to add the proper fluid
until the level reaches the MIN line.
