WARNING:Do not exceed the GVWR or the GAWR specified on
the certification label.
WARNING:Towing trailers beyond the maximum recommended
gross trailer weight exceeds the limit of the vehicle and could
result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.
Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. Contact your authorized dealer or a
reliable trailer dealer as soon as possible if you require assistance.
Hitches
Do not use hitches that clamp onto the vehicle bumper. Use a load
carrying hitch. You must distribute the load in your trailer so that
10–15% of the total weight of the trailer is on the tongue.
Safety chains
Always connect the trailer’s safety chains to hook retainers on the
vehicle. To connect the trailer’s safety chains, cross the chains under the
trailer tongue and allow slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Electric, manual, automatic or surge-type brakes, if compatible with the
vehicle, are safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.
WARNING:Do not connect a trailer’s hydraulic brake system
directly to your vehicle’s brake system. Your vehicle may not
have enough braking power and your chances of having a collision
greatly increase.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.

•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
When backing down a ramp during boat launching or retrieval:
•do not allow the static water level to rise above the bottom edge of
the rear bumper.
•do not allow waves to break higher than 6 inches (15 cm) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter vehicle components:
•causing internal damage to the components.
•affecting driveability, emissions and reliability.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
RECREATIONAL TOWING
Follow these guidelines for your specific powertrain combination to tow
your vehicle for personal travel (such as behind a motor home or a
truck).
Note:Put your climate control system in recirculated air mode to
prevent exhaust fumes from entering the vehicle. Refer to theClimate
controlschapter for more information.
In case of roadside emergency with a disabled vehicle, please refer to
Wrecker towingin theRoadside Emergencieschapter.

STARTING
Positions of the ignition
1. Off— locks the gearshift lever
and steering column and allows key
removal.
2. Accessory— allows the electrical
accessories such as the radio to
operate while the engine is not
running.
3. On— all electrical circuits
operational and warning lights will
illuminate. This is the position the
key is in when you’re driving.
4. Start— cranks the engine. Release the key as soon as the engine
starts.
Preparing to start your vehicle
Engine starting is controlled by the powertrain control system.
This system meets all Canadian interference-causing equipment standard
requirements regulating the impulse electrical field strength of radio
noise.
When starting a fuel-injected engine, avoid pressing the accelerator
before or during starting. Only use the accelerator when you have
difficulty starting the engine. For more information on starting the
vehicle, refer toStarting the enginein this chapter.
WARNING:Extended idling at high engine speeds can produce
very high temperatures in the engine and exhaust system,
creating the risk of fire or other damage.
WARNING:Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.
WARNING:Do not start your vehicle in a closed garage or in
other enclosed areas. Exhaust fumes can be toxic. Always open
the garage door before you start the engine. SeeGuarding against
exhaust fumesin this chapter for more instructions.

WARNING:If you smell exhaust fumes inside your vehicle, have
your dealer inspect your vehicle immediately. Do not drive if you
smell exhaust fumes.
Important safety precautions
A computer system controls the engine’s idle revolutions per minute
(RPM). When the engine starts, the idle RPM runs higher than normal in
order to warm the engine. If the engine idle speed does not slow down
automatically, have the vehicle checked.
Before starting the vehicle:
1. Make sure all vehicle occupants have buckled their safety belts. For
more information on safety belts and their proper usage, refer to the
Seating and Safety Restraintschapter.
2. Make sure vehicle accessories are off.
•Make sure the parking brake is
set.

Starting the engine
1. Turn the key to 3 (on) without
turning the key to 4 (start). If there
is difficulty in turning the key,
rotate the steering wheel until the
key turns freely. This condition may
occur when:
•the front wheels are turned
•a front wheel is against the curb
2. Turn the key to 4 (start), then
release the key as soon as the
engine begins cranking. Your vehicle has a computer assisted cranking
system that assists in starting the engine. After releasing the key from
the 4 (start) position, the engine may continue cranking for up to
10 seconds or until the vehicle starts.
Note:Cranking may be stopped at any time by turning the key to the off
position.
3. After idling for a few seconds, release the parking brake, apply the
brake, shift into gear and drive.
Note:If the engine does not start on the first try, turn the key to the off
position, wait 10 seconds and try Step 2 again. If the engine still fails to
start, press the accelerator to the floor and try Step 2 again, keeping the
accelerator on the floor until the engine begins to accelerate above
cranking speeds; this will allow the engine to crank with the fuel shut off
in case the engine is flooded with fuel.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
WARNING:If you smell exhaust fumes inside your vehicle, have
your dealer inspect your vehicle immediately. Do not drive if you
smell exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least one inch (2.5 cm) or adjust the heating
or air conditioning to bring in fresh air.
ENGINE BLOCK HEATER (IF EQUIPPED)
An engine block heater warms the engine coolant which aids in starting
and allows the heater/defroster system to respond quickly. If your vehicle
2009 Mariner(mrn)
Owners Guide, 2nd Printing

is equipped with this system, your equipment includes a heater element
which is installed in your engine block and a wire harness which allows
the user to connect the system to a grounded 120 volt a/c electrical
source. The block heater system is most effective when outdoor
temperatures reach below 0°F (-18°C).
WARNING:Failure to follow engine block heater instructions
could result in property damage or physical injury.
WARNING:To reduce the risk of electrical shock, do not use
your heater with ungrounded electrical systems or two-pronged
(cheater) adapters.
Prior to using the engine block heater, follow these recommendations for
proper and safe operation:
•For your safety, use an outdoor extension cord that is product
certified by Underwriter’s Laboratory (UL) or Canadian Standards
Association (CSA). Use only an extension cord that can be used
outdoors, in cold temperatures, and is clearly markedSuitable for Use
with Outdoor Appliances.Never use an indoor extension cord
outdoors; it could result in an electric shock or fire hazard.
•Use a 16 gauge outdoor extension cord, minimum.
•Use as short an extension cord as possible.
•Do not use multiple extension cords. Instead, use one extension cord
which is long enough to reach from the engine block heater cord to
the outlet without stretching.
•Make certain that the extension cord is in excellent condition (not
patched or spliced). Store your extension cord indoors at
temperatures above 32°F (0°C). Outdoor conditions can deteriorate
extension cords over a period of time.
•To reduce the risk of electrical shock, do not use your heater with
ungrounded electrical systems or two pronged (cheater) adapters.
Also ensure that the block heater, especially the cord, is in good
condition before use.
•Make sure that when in operation, the extension cord plug /engine
block heater cord plug connection is free and clear of water in order
to prevent possible shock or fire.
•Be sure that areas where the vehicle is parked are clean and clear of
all combustibles such as petroleum products, dust, rags, paper and
similar items.
