brake PONTIAC VIBE 2007 Service Manual

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.
Trailer Brakes
Does your trailer have its own brakes?
Be sure to read and follow the instructions for the
trailer brakes so you’ll be able to install, adjust
and maintain them properly. And, if you have
anti-lock brakes, do not try to tap into your
vehicle’s brake system. If you do, both systems
won’t work well, or at all.
Driving with a Trailer
Towing a trailer requires a certain amount of
experience. Before setting out for the open road,
you’ll want to get to know your rig. Acquaint
yourself with the feel of handling and braking with
the added weight of the trailer. And always
keep in mind that the vehicle you are driving is
now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch, platform
and attachments, safety chains, electrical
connector, lamps, tires and mirror adjustment. If
the trailer has electric brakes, start your vehicle
and trailer moving and then apply the trailer brake
controller by hand to be sure the brakes are
working. This lets you check your electrical
connection at the same time.
During your trip, check occasionally to be sure
that the load is secure, and that the lamps and any
trailer brakes are still working.
265

Driving On Grades
Reduce speed and shift to a lower gearbefore
you start down a long or steep downgrade. If you
don’t shift down, you might have to use your
brakes so much that they would get hot and no
longer work well.
On a long uphill grade, shift down and reduce
your speed to around 45 mph (70 km/h) to reduce
the possibility of the engine and the transaxle
overheating.
Parking on Hills
{CAUTION:
You really should not park your vehicle,
with a trailer attached, on a hill. If
something goes wrong, your rig could
start to move. People can be injured, and
both your vehicle and the trailer can be
damaged.But if you ever have to park your rig on a hill,
here’s how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) for an automatic transaxle or into
gear for a manual transaxle, yet. When
parking uphill, turn your wheels away from the
curb. When parking downhill, turn your
wheels into the curb.
2. Have someone place chocks under the trailer
wheels.
3. When the chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your
parking brake and shift into PARK (P) for an
automatic transaxle or REVERSE (R) for
a manual transaxle.
5. Release the regular brakes.
267

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal
down while you:
start your engine
shift into a gear, and
release the parking brake
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the
chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when
you’re pulling a trailer. See the Maintenance
Schedule for more on this. Things that are
especially important in trailer operation are
automatic transaxle uid (don’t overll), engine oil,
drive belt, cooling system and brake system.
Each of these is covered in this manual, and the
Index will help you nd them quickly. If you’re
trailering, it’s a good idea to review this information
before you start your trip.
Check periodically to see that all hitch nuts and
bolts are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat
during severe operating conditions. SeeEngine
Overheating on page 297.

Checking Things Under
the Hood
{CAUTION:
An electric fan under the hood can start up
and injure you even when the engine is not
running. Keep hands, clothing, and tools
away from any underhood electric fan.
{CAUTION:
Things that burn can get on hot engine
parts and start a re. These include
liquids like fuel, oil, coolant, brake uid,
windshield washer and other uids, and
plastic or rubber. You or others could be
burned. Be careful not to drop or spill
things that will burn onto a hot engine.
Hood Release
To open the hood, do the following:
1. Pull the release
handle with this
symbol on it.
It is located below
the instrument panel
to the left of the
steering wheel.

Checking the Fluid Level
Prepare your vehicle as follows:
1. Park your vehicle on a level place. Keep the
engine running.
2. With the parking brake applied, place the shift
lever in PARK (P).
3. With your foot on the brake pedal, move the
shift lever through each gear range, pausing
for about three seconds in each range.
Then, position the shift lever in PARK (P).
4. Let the engine run at idle for three to
ve minutes.Then, without shutting off the engine, follow
these steps:
The automatic transaxle dipstick has an orange
handle and is located near the front of the engine
compartment. SeeEngine Compartment Overview
on page 282for more information on location.
1. Release the tab and pull out the dipstick and
wipe it with a clean rag or paper towel.
2. Push it back in all the way, wait three seconds
and then pull it back out again.
3. Check both sides of the dipstick, and read the
lower level. The uid level must be between
the two dimples in the hot range.
4. If the uid level is in the acceptable range,
push the dipstick back in all the way; then
press the tab down to lock the dipstick in place.
291

Check the uid level only when your engine is off,
the vehicle is parked on a level place and the
transaxle is cool enough for you to rest your
ngers on the transaxle case.
Then, follow these steps:
1. Remove the ller plug.
2. Check that the lubricant level is up to the
bottom of the ller plug hole.
3. If the uid level is good, install the plug and be
sure it is fully seated. If the uid level is low,
add more uid as described in the next steps.
How to Add Fluid
Here is how to add uid. Refer to the Maintenance
Schedule to determine what kind of uid to use.
SeePart D: Recommended Fluids and Lubricants
on page 394.
1. Remove the ller plug.
2. Add uid at the ller plug hole. Add only
enough uid to bring the uid level up to
the bottom of the ller plug hole.
3. Install the ller plug. Be sure the plug is fully
seated.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. The master cylinder reservoir
is lled with DOT-3 brake uid.
It is not necessary to regularly check the uid
unless you suspect there is a leak in the system.
Adding uid will not correct a leak.
The hydraulic clutch and brake master cylinder
use the same reservoir.
A uid loss in this system could indicate a
problem. Have the system inspected and repaired.
293

Brakes
Brake Fluid
The hydraulic clutch and
brake master cylinder
use the same reservoir.
It is lled with DOT-3
brake uid. SeeEngine
Compartment
Overview on page 282
for the location of
the reservoir.
There are only two reasons why the brake uid
level in the reservoir might go down. The rst
is that the brake uid goes down to an acceptable
level during normal brake lining wear. When
new linings are put in, the uid level goes back
up. The other reason is that uid is leaking out of
the brake system or the hydraulic clutch system.
If it is, have that system xed immediately, since a
leak means that the brakes will not work well, or
will not work at all.So, it is not a good idea to top off the brake uid.
Adding brake uid will not correct a leak. If
you add uid when the linings are worn, then you
will have too much uid when you get new
brake linings. You should add or remove brake
uid, as necessary, only when work is done on the
brake hydraulic system.
{CAUTION:
If your vehicle has too much brake uid, it
can spill on the engine. The uid will burn
if the engine is hot enough. You or others
could be burned, and your vehicle could
be damaged. Add brake uid only when
work is done on the brake and/or clutch
hydraulic system.
When the brake uid falls to a low level, the brake
warning light will come on. SeeBrake System
Warning Light on page 166.
