{WARNING
Wheel nuts that are improperly or
incorrectly tightened can cause
the wheels to become loose or
come off. The wheel nuts should
be tightened with a torque wrench
to the proper torque specification
after replacing. Follow the torque
specification supplied by the
aftermarket manufacturer when
using accessory locking wheel
nuts. SeeCapacities and
Specifications on page 12‑2 for
original equipment wheel nut
torque specifications.
Notice: Improperly tightened
wheel nuts can lead to brake
pulsation and rotor damage. To
avoid expensive brake repairs,
evenly tighten the wheel nuts in
the proper sequence and to the
proper torque specification. See
Capacities and Specifications on
page 12‑2 for the wheel nut
torque specification.
11. Use the wheel wrench to tighten the nuts firmly. Turn the
wheel wrench clockwise and in
a crisscross sequence as
shown. 12. Put the wheel cover or the
center cap and plastic wheel
nut caps back on. Remove any
wheel blocks.
Have a technician check the
wheel nut tightness of all
wheels with a torque wrench
after the first 160 km
(100 miles) and then 1600 km
(1,000 miles) after that. Repeat
this service whenever you have
a tire removed or serviced. See
Capacities and Specifications
on page 12‑2 for more
information.

6. Connect the red positive (+)cable to the positive (+) terminal
of the dead battery. Use a
remote positive (+) terminal if the
vehicle has one. Do not let the
other end touch metal. Connect
it to the positive (+) terminal of
the good battery. Use a remote
positive (+) terminal if the vehicle
has one.
7. Now connect the black negative (−) cable to the
negative (−) terminal of the good
battery. Use a remote
negative (−) terminal if the
vehicle has one. Do not let the other end touch
anything until the next step. The
other end of the negative (−)
cable does not go to the dead
battery. It goes to a heavy,
unpainted metal engine part or
to a remote negative (−) terminal
on the vehicle with the dead
battery. On your van, use the
unpainted radio antenna bracket
as a remote negative (−)
terminal.
8. Connect the other end of the
negative (−) cable to the
negative (−) terminal location on the vehicle with the dead battery.
On your van, use the unpainted
radio antenna bracket as a
remote negative (−) terminal.
Notice: Your vehicle uses the
unpainted radio antenna bracket
as a remote negative (−) terminal.
Move the antenna coax cable out
of the way before clamping the
negative jumper cable to the fixed
antenna bracket. Avoid touching
the negative cable clamp to the
air conditioning line. Failure to do
either of these could damage
your vehicle. The repairs would
not be covered by the warranty.
9. Now start the vehicle with the
good battery and run the engine
for a while.
10. Try to start the vehicle that had the dead battery. If it will not
start after a few tries, it
probably needs service.

Towing
Towing the Vehicle
Notice:To avoid damage, the
disabled vehicle should be towed
with all four wheels off the
ground. Care must be taken with
vehicles that have low ground
clearance and/or special
equipment. Always flatbed on a
car carrier.
Consult your dealer or a
professional towing service if the
disabled vehicle must be towed.
See Roadside Assistance Program
on page 13‑6.
To tow the vehicle behind another
vehicle for recreational purposes,
such as behind a motorhome, see
“Recreational Vehicle Towing” in this
section.
Recreational Vehicle
Towing
Recreational vehicle towing means
towing the vehicle behind another
vehicle –such as behind a motor
home. The two most common types
of recreational vehicle towing are
known as dinghy towing and dolly
towing. Dinghy towing is towing the
vehicle with all four wheels on the
ground. Dolly towing is towing the
vehicle with two wheels on the
ground and two wheels up on a
device known as a dolly. Here are some important things to
consider before recreational vehicle
towing:.What is the towing capacity
of the towing vehicle? Be
sure to read the tow vehicle
manufacturer's
recommendations.
.What is the distance that will be
travelled? Some vehicles have
restrictions on how far and how
long they can tow.
.Is the proper towing equipment
going to be used? See your
dealer or trailering professional
for additional advice and
equipment recommendations.
.Is the vehicle ready to be
towed? Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed.

General Information
This maintenance section applies to
vehicles with a gasoline engine. For
diesel engine vehicles, see the
maintenance schedule section in
the Duramax Diesel Supplement.
Notice: Maintenance intervals,
checks, inspections,
recommended fluids, and
lubricants are necessary to keep
this vehicle in good working
condition. Damage caused by
failure to follow scheduled
maintenance might not be
covered by the vehicle warranty. As the vehicle owner, you are
responsible for the scheduled
maintenance in this section. We
recommend having your dealer
perform these services. Proper
vehicle maintenance helps to keep
the vehicle in good working
condition, improves fuel economy,
and reduces vehicle emissions for
better air quality.
Because of all the different ways
people use vehicles, maintenance
needs vary. The vehicle might need
more frequent checks and services.
Please read the information under
Scheduled Maintenance. To keep
the vehicle in good condition, see
your dealer.

of genuine parts from your dealer.
Rotation of New Tires
To maintain ride, handling, and
performance of the vehicle, it is
important that the first rotation
service for new tires be performed.

Engine Oil on page 10‑7.An
Emission Control Service.
When the CHANGE ENGINE OIL
SOON message displays, service is
required for the vehicle as soon as
possible, within the next 1 000 km/
600 mi. If driving under the best
conditions, the engine oil life system
might not indicate the need for
vehicle service for more than a year.
The engine oil and filter must be
changed at least once a year and
the oil life system must be reset. Your dealer has trained service
technicians who will perform this
work and reset the system. If the
engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 mi since the
last service. Reset the oil life
system whenever the oil is changed.
