tow PONTIAC TORRENT 2007 Service Manual

Notice:If your engine catches re because
you keep driving with no coolant, your vehicle
can be badly damaged. The costly repairs
would not be covered by your warranty. See
Overheated Engine Protection Operating Mode
on page 362for information on driving to a
safe place in an emergency.
If No Steam Is Coming From
Your Engine
An overheat warning can indicate a serious
problem.
If you get an engine overheat warning, but see or
hear no steam, the problem may not be too
serious. Sometimes the engine can get a little too
hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.If you get the overheat warning with no sign of
steam, try this for a minute or so:
1. If the air conditioner is on, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the windows as necessary.
3. Try to minimize engine load. If you are in a
traffic jam, shift to NEUTRAL (N); otherwise,
shift to the highest gear while driving.
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for
about ten minutes. If the warning does not come
back on, you can drive normally.
If the warning continues and you have not
stopped, pull over, stop, and park your vehicle
right away.
If there is still no sign of steam, you can idle the
engine for three minutes while you are parked.
If you still have the warning, turn off the engine
and get everyone out of the vehicle until it
cools down. Also, see “Overheated Engine
Protection Operating Mode” later in this section.
You may decide not to lift the hood but to get
service help right away.

Overheated Engine Protection
Operating Mode
This emergency operating mode lets your vehicle
be driven to a safe place in an emergency situation.
If an overheated engine condition exists, an
overheat protection mode which alternates ring
groups of cylinders helps prevent engine damage.
In this mode, there is a signicant loss in power and
engine performance. The temperature gage
indicates an overheat condition exists. Driving
extended miles (km) and/or towing a trailer in the
overheat protection mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil will be
severely degraded. Repair the cause of coolant
loss, change the oil and reset the oil life system.
SeeEngine Oil on page 349.

Do not include the compact spare tire in your tire
rotation.
After the tires have been rotated, adjust the
front and rear ination pressures as shown on
the Tire and Loading Information label. See
Ination - Tire Pressure on page 393andLoading
Your Vehicle on page 321.
Reset the Tire Pressure Monitor System. See
“TPMS Sensor Matching Process” under
Tire Pressure Monitor System on page 395.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications on page 436.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if needed, to get all the rust or dirt
off. SeeChanging a Flat Tire on page 408.

If a Tire Goes Flat
It is unusual for a tire to blowout while you are
driving, especially if you maintain your vehicle’s
tires properly. If air goes out of a tire, it is
much more likely to leak out slowly. But if you
should ever have a blowout, here are a few tips
about what to expect and what to do:
If a front tire fails, the at tire will create a drag
that pulls the vehicle toward that side. Take your
foot off the accelerator pedal and grip the
steering wheel rmly. Steer to maintain lane
position, and then gently brake to a stop well out
of the traffic lane.
A rear blowout, particularly on a curve, acts much
like a skid and may require the same correction
you would use in a skid. In any rear blowout
remove your foot from the accelerator pedal. Get
the vehicle under control by steering the way
you want the vehicle to go. It may be very bumpy
and noisy, but you can still steer. Gently brake
to a stop, well off the road if possible.{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous
without the appropriate safety equipment
and training. The jack provided with your
vehicle is designed only for changing a
at tire. If it is used for anything else, you
or others could be badly injured or killed
if the vehicle slips off the jack. Use the
jack provided with your vehicle only for
changing a at tire.
If a tire goes at, the next part shows how to use
the jacking equipment to change a at tire safely.

9. Remove all of the
wheel nuts.
10. Remove the at tire.
{CAUTION:
Rust or dirt on the wheel, or on the parts
to which it is fastened, can make the
wheel nuts become loose after time. The
wheel could come off and cause an
accident. When you change a wheel,
CAUTION: (Continued)
CAUTION: (Continued)
remove any rust or dirt from the places
where the wheel attaches to the vehicle. In
an emergency, you can use a cloth or a
paper towel to do this; but be sure to use
a scraper or wire brush later, if needed, to
get all the rust or dirt off.
11. Remove any rust or
dirt from the wheel
bolts, mounting
surfaces, and spare
wheel.

Notice:Wheelcovers will not t on your
compact spare. If you try to put a wheel cover
on the compact spare, you could damage
the cover or the spare.
Do not try to put a wheel cover on your compact
spare tire. It will not t. Store the wheel cover in the
cargo area until you have the at tire repaired or
replaced.
Storing a Flat or Spare Tire and
Tools
{CAUTION:
Storing a jack, a tire, or other equipment
in the passenger compartment of the
vehicle could cause injury. In a sudden
stop or collision, loose equipment could
strike someone. Store all these in the
proper place.To store the at tire or the spare tire and tools, do
the following:
1. Place the wheel wrench into the bag.
2. Use the hook and loop fastener straps to
secure the bag to the jack.
3. Install the jack in the
left side panel of
cargo area and
secure it with the
wing bolt.
4. Remove the wheel stow rod from the left side
of the oor compartment.

wheel stow rod must be turned to the farthest
forward position.6. If your vehicle has a cap, remove the cap
from the center of the load oor. Position
the rod through the hole.
7. Place the at, or damaged tire, face down,
on the load oor with the threaded wheel
stow rod sticking up through the center hole
of the wheel.
8. Install the nut onto the wheel stow rod and
tighten.
9. If your vehicle has a rear compartment
storage panel/cover, reinstall the panel/cover
in either the center or upper position. See
