Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and the
front and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that
it is not over the GVWR.
Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle’s
GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight, axle-by-axle and side-by-side. Store heavier items
down low and be sure you distribute their weight as
evenly as possible. Stow all loose items securely before
driving. If weighing the loaded vehicle shows that you
have exceeded either GAWR, but the total load is within
the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
NOTE:Refer to the “Vehicle Certification Label” affixed
to the rear of the driver’s door for your vehicle’s GVWR
and GAWRs.
TRAILER TOWING
Trailer towing with this vehicle is not recommended.

WARNING!(Continued)
•TIREFIT Sealant solution contains latex. In case of
an allergic reaction or rash, consult a physician
immediately. Keep TIREFIT out of reach of chil-
dren. If swallowed, rinse mouth immediately with
plenty of water and drink plenty of water. Do not
induce vomiting! Consult a physician immediately.
Sealing A Tire With TIREFIT
(A) Whenever You Stop To Use TIREFIT:
1. Pull over to a safe location and turn on the vehicle’s Hazard Warning flashers.
2. Verify that the valve stem (on the wheel with the deflated tire) is in a position that is near to the ground.
This will allow the TIREFIT Hoses (6) and (7) to reach
the valve stem and keep the TIREFIT kit flat on the
ground. This will provide the best positioning of the kit when injecting the sealant into the deflated tire and
running the air pump. Move the vehicle as necessary
to place the valve stem in this position before proceed-
ing.
3. Place the transmission in PARK (auto transmission) or in Gear (manual transmission) and turn Off the igni-
tion.
4. Set the parking brake.
(B) Setting Up To Use TIREFIT:
1. Push in the Mode Select Knob (5) and turn to the Sealant Mode position.
2. Uncoil the Sealant Hose (6) and then remove the cap from the fitting at the end of the hose.
3. Place the TIREFIT kit flat on the ground next to the deflated tire.

4. Remove the cap from the valve stem and then screwthe fitting at the end of the Sealant Hose (6) onto the
valve stem.
5. Uncoil the Power Plug (8) and insert the plug into the vehicle’s 12 Volt power outlet.
NOTE: Do not remove foreign objects (e.g., screws or
nails) from the tire.
(C) Injecting TIREFIT Sealant Into The Deflated
Tire:
• Always start the engine before turning ON the TIRE-
FIT kit.
NOTE: Manual transmission vehicles must have the
parking brake engaged and the shift lever in NEUTRAL.
• After pressing the Power Button (4), the sealant (white
fluid) will flow from the Sealant Bottle (1) through the
Sealant Hose (6) and into the tire. NOTE:
Sealant may leak out through the puncture in the
tire.
If the sealant (white fluid) does not flow within0–10
seconds through the Sealant Hose (6):
1. Press the Power Button (4) to turn Off the TIREFIT kit. Disconnect the Sealant Hose (6) from the valve stem.
Make sure the valve stem is free of debris. Reconnect
the Sealant Hose (6) to the valve stem. Check that the
Mode Select Knob (5) is in the Sealant Mode position
and not Air Mode. Press the Power Button (4) to turn
On the TIREFIT kit.
2. Connect the Power Plug (8) to a different 12 Volt power outlet in your vehicle or another vehicle, if
available. Make sure the engine is running before
turning ON the TIREFIT kit.
3. The Sealant Bottle (1) may be empty due to previous use. Call for assistance.

WARNING!
•Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is ON. You can be injured by
moving fan blades.
• Remove any metal jewelry such as rings, watch
bands and bracelets that could make an inadvertent
electrical contact. You could be seriously injured.
• Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
1. Set the parking brake, shift into PARK (automatic transmission) or 1st gear (manual transmission) and
turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electri- cal accessories. 3. If using another vehicle to jump-start the battery, park
the vehicle within the jumper cables reach, set the
parking brake and make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this jump-starting procedure could
result in personal injury or property damage due to
battery explosion.

CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the transmission in NEUTRAL for at
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce
the risk of clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
NOTE: Press the ESC Off switch, to place the Electronic
Stability Control (ESC) system in Partial Offmode,
before rocking the vehicle. Refer to “Electronic Brake
Control” in “Starting And Operating” for further infor-
mation. Once the vehicle has been freed, press the ESC
Off switch again to restore ESC Onmode.
CAUTION!
•When “rocking” a stuck vehicle by shifting be-
tween DRIVE and REVERSE (with automatic
transmission) or FIRST GEAR and REVERSE (with
manual transmission), do not spin the wheels
faster than 15 mph (24 km/h), or drivetrain damage
may result.
• Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no trans-
mission shifting occurring).
410 WHAT TO DO IN EMERGENCIES

WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause damage, or
even failure, of the axle and tires. A tire could
explode and injure someone. Do not spin your vehi-
cle’s wheels faster than 30 mph (48 km/h) or for
longer than 30 seconds continuously without stop-
ping when you are stuck and do not let anyone near
a spinning wheel, no matter what the speed.
SHIFT LEVER OVERRIDE
If a malfunction occurs and the shift lever cannot be
moved out of the PARK position, you can use the
following procedure to temporarily move the shift lever:
1. Turn the engine OFF.
2. Firmly apply the parking brake.
3. Using a small screwdriver or similar tool, remove theshift lever override access cover (located to the right of
the shift lever).
4. Press and maintain firm pressure on the brake pedal.
5. Insert the screwdriver or similar tool into the access hole, and push and hold the override release lever
down.
