What Fuel to Use in Canada
Notice:Use of diesel fuel other than Ultra Low
Sulfur Diesel (15 ppm sulfur maximum) or engine oil
other than low ash CJ-4 oil will cause permanent
damage to the DPF and related components.
This damage would not be covered by your
warranty.
The emission control system requires the use of diesel
fuel with ultra low-sulfur (0.0015% by weight, or 15 ppm,
maximum) content. Both Ultra Low Sulfur Diesel and Low
Sulfur Diesel fuels are available in the United States and
Ultra Low Sulfur Diesel fuel is available in Canada.
However, only higher sulfur diesel fuel is available
in Mexico.
At a minimum, the diesel fuel you use should meet the
latest version of specification CAN/CGSB-3.517 (ULS) in
Canada. In addition, the Engine Manufacturers
Association (EMA) has identified properties of an
improved diesel fuel for better engine performance and
durability (FQP-1A). Diesel fuels corresponding to the
EMA description could provide better starting, less noise,
and better vehicle performance. If there are questions
about the fuel you are using, contact your fuel supplier.Canadian fuels are blended for seasonal changes.
Diesel Type “A” fuel is blended for better cold weather
starting (below 0°F or−18°C); however, you might notice
some power and fuel economy loss. If Type “A” fuel is
used in warmer temperatures, stalling and hard
starting may occur. Diesel Type “B” fuel is blended for
temperatures above 0°F (−18°C).
It is acceptable to use diesel fuel containing up to
5% biodiesel (B5), but the final blended fuel must meet
the same specification, CAN/CGSB-3.517 (ULS) in
Canada, as other fuels used in your vehicle, and the
biodiesel used for making this fuel must meet the latest
version of ASTM specification D 6751. Biodiesel is
produced from vegetable oils or animal fat that have been
chemically modified to reduce the possibility of damage to
the fuel system and engine. Higher concentration (i.e.,
greater than B5) biodiesel-containing fuels or the use of
unmodified bio-oils blended into diesel fuel at any
concentration is not recommended and could damage the
fuel system and engine. Such damage would not be
covered by your warranty. If there are questions about
the biodiesel-containing fuels you are using, contact your
fuel supplier.

Hood Inlet Seal
If your vehicle is being used in heavy snow conditions
or for snow plowing, there is a possibility of snow and
ice build up in the inlet to the air cleaner, blocking airflow
to the engine and negatively impacting engine
performance.
To prevent the blocking of air, remove the hood inlet
seal, by doing the following:
1. Loosen the clamp that holds the seal to the air
cleaner.
2. Slide the seal off.3. Store the seal in the inlet, located on the underside
of the hood.
4. Store the clamp on the coolant surge tank. Pull the
overflow tube out of the white plastic retainer, slip
the clamp over and reinstall the hose.
The seal will need to be replaced on to the air cleaner
for normal driving, especially in the warmer months.

Jump Starting
If your vehicle’s battery (or batteries) has run down, you
may want to use another vehicle and some jumper
cables to start your vehicle. Be sure to use the following
steps to do it safely.
{CAUTION:
Batteries can hurt you. They can be dangerous
because:
They contain acid that can burn you.
They contain gas that can explode or
ignite.
They contain enough electricity to
burn you.
If you do not follow these steps exactly, some
or all of these things can hurt you.
Notice:Ignoring these steps could result in costly
damage to your vehicle that would not be covered
by your warranty.Trying to start your vehicle by pushing or pulling it
will not work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery (or batteries) with a negative ground system.
Notice:If the other vehicle’s system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
If you have a diesel engine vehicle with
two batteries (or more), you should know before
you begin that, especially in cold weather, you may
not be able to get enough power from a single
battery in another vehicle to start your diesel engine.
If your vehicle has more than one battery, use the
one closest to the starter — this will reduce electrical
resistance.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles are not touching
each other. If they are, it could cause a ground
connection you do not want. You would not be able
to start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump start procedure. Put an automatic
transmission in PARK (P) or a manual transmission
in NEUTRAL before setting the parking brake.
If you have a four-wheel-drive vehicle, be sure the
transfer case is in a drive gear, not in NEUTRAL.

Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You cannot know how it has been
used or how far it has been driven. It could fail
suddenly and cause a crash. If you have to
replace a wheel, use a new GM original
equipment wheel.
If a Tire Goes Flat
It is unusual for a tire to blowout while you are driving,
especially if you maintain your 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 flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly. 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.
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place and turn on your
hazard warning flashers. SeeHazard Warning Flashers
on page 3-6.

Automatic Transmission Shift Indicator
Check
Check that the indicator points to the gear chosen.
Steering Check
Be alert for any changes in steering action, abnormal
front tire wear or steering wheel position. An inspection
or service is needed when the steering wheel is harder
to turn or has too much free play, or if there are strange
sounds when turning or parking.
Brake System Check
Be alert to the low air warning light or tone alarm, or
changes in braking action, such as repeated pulling to
one side, unusual sounds when braking or increased
brake pedal travel. Make sure air brake system
reservoirs are drained daily with full system air pressure,
and check system for leaks. Any of these conditions
could indicate the need for brake system inspection
and/or service.
Engine Cooling System Service
Inspect the hoses and have them replaced if they are
cracked, swollen, or deteriorated. Inspect all pipes,
fittings, and clamps; replace as needed. Clean the
outside of the radiator and air conditioning condenser.
To help ensure proper operation, a pressure test of the
cooling system and pressure cap is recommended at
least once a year.
Exhaust System Inspection
Be alert for any changes in the sound of the exhaust
system or any smell of fumes. These are signs the
system may be leaking. Have it checked and/or repaired
at once. SeeEngine Exhaust on page 2-45and
Running the Vehicle While Parked on page 2-50.
Check to be sure that mud or dirt is not caked on the
exhaust system, especially in the area of the diesel
particulate filter and tailpipe. Clean the area as needed.
SeeDiesel Particulate Filter (Diesel Engine) on
page 2-46.
At high mileages, the DPF becomes loaded with ash.
This is normal. When the amount of ash loading is high,
see your dealer/retailer for DPF cleaning or replacement.

Customer Assistance and
Information
Customer Satisfaction Procedure
Your satisfaction and goodwill are important to
your dealer and to Chevrolet. Normally, any concerns
with the sales transaction or the operation of your
vehicle will be resolved by your dealer’s sales or service
departments. Sometimes, however, despite the best
intentions of all concerned, misunderstandings can
occur. If your concern has not been resolved to your
satisfaction, the following steps should be taken:
STEP ONE:Discuss your concern with a member of
dealership management. Normally, concerns can
be quickly resolved at that level. If the matter has
already been reviewed with the sales, service or parts
manager, contact the owner of the dealership or
the general manager.STEP TWO:If after contacting a member of
dealership management, it appears your concern
cannot be resolved by the dealership without further
help, contact the GM Medium Duty Truck Customer
Assistance Center at 1-800-862-4389. In Canada,
contact GM of Canada Customer Communication Centre
in Oshawa by calling 1-800-263-3777 (English) or
1-800-263-7854 (French).
We encourage you to call the toll-free number in order
to give your inquiry prompt attention. Please have
the following information available to give the Customer
Assistance Representative:
•Vehicle Identification Number (VIN). This is
available from the vehicle registration or title, or the
plate at the top left of the instrument panel and
visible through the windshield.
•Dealership name and location.
•Vehicle delivery date and present mileage
(kilometers).
When contacting Chevrolet, please remember that your
concern will likely be resolved at a dealer’s facility.
That is why we suggest you follow Step One first if you
have a concern.
7-2
•Gather the important information you will need from
the other driver. Things like name, address, phone
number, driver’s license number, vehicle license
plate, vehicle make, model and model year, Vehicle
Identification Number (VIN), insurance company and
policy number, and a general description of the
damage to the other vehicle.
•If possible, call your insurance company from the
scene of the crash. They will walk you through the
information they will need. If they ask for a police
report, phone or go to the police department
headquarters the next day and you can get a copy of
the report for a nominal fee. In some states/provinces
with “no fault” insurance laws, a report may not be
necessary. This is especially true if there are no
injuries and both vehicles are driveable.
•Choose a reputable collision repair facility for your
vehicle. Whether you select a dealer/retailer or a
private collision repair facility to fix the damage,
make sure you are comfortable with them.
Remember, you will have to feel comfortable with
their work for a long time.
•Once you have an estimate, read it carefully and
make sure you understand what work will be
performed on your vehicle. If you have a question,
ask for an explanation. Reputable shops welcome
this opportunity.
Managing the Vehicle Damage Repair
Process
In the event that your vehicle requires damage repairs,
GM recommends that you take an active role in its
repair. If you have a pre-determined repair facility of
choice, take your vehicle there, or have it towed there.
Specify to the facility that any required replacement
collision parts be original equipment parts, either new
Genuine GM parts or recycled original GM parts.
Remember, recycled parts will not be covered by your
GM vehicle warranty.
Insurance pays the bill for the repair, but you must live
with the repair. Depending on your policy limits, your
insurance company may initially value the repair using
aftermarket parts. Discuss this with your repair
professional, and insist on Genuine GM parts. Remember
if your vehicle is leased you may be obligated to have the
vehicle repaired with Genuine GM parts, even if your
insurance coverage does not pay the full cost.
If another party’s insurance company is paying for the
repairs, you are not obligated to accept a repair
valuation based on that insurance company’s collision
policy repair limits, as you have no contractual limits with
that company. In such cases, you can have control of
the repair and parts choices as long as cost stays within
reasonable limits.
