Removingkeyfrom ignition
•Turn the ignition key
to position 3 (OFF).
•Push the release
lever forward and
rotate the key
towards you and
remove.
DRIVING THROUGH WATER
Do not drive quickly through standing water,
especially if the depth is unknown. Traction or brake
capability may be limited and if the ignition system
gets wet, your engine may stall. Water may also
enter your engine’s air intake and severely damage
your engine.
If driving through deep or standing water is
unavoidable, proceed very slowly. Never drive
through water that is higher than the bottom of the
hubs (for trucks) or the bottom of the wheel rims
(for cars).
Once through the water, always try the brakes. Wet
brakes do not stop the vehicle as effectively as dry
brakes. Drying can be improved by moving your
vehicle slowly while applying light pressure on the
brake pedal.
Driving through deep water where the
transmission vent tube is submerged may allow
water into the transmission and cause internal
transmission damage. Have the fluid checked
and, if water is found, replace the fluid.

VEHICLE LOADING
Before loading a vehicle, familiarize yourself with the
following terms:
•Base Curb Weight:Weight of the vehicle
including any standard equipment, fluids,
lubricants, etc. It does not include occupants or
aftermarket equipment.
•Payload:Combined maximum allowable weight of
cargo, occupants and optional equipment. The
payload equals the gross vehicle weight rating
minus base curb weight.
•GVW (Gross Vehicle Weight):Base curb weight
plus payload weight. The GVW is not a limit or a
specification.
•GVWR (Gross Vehicle Weight Rating):
Maximum permissible total weight of the base
vehicle, occupants, optional equipment and cargo.
The GVWR is specific to each vehicle and is listed
on the Safety Certification Label on the driver’s
door pillar.
•GAWR (Gross Axle Weight Rating):Carrying
capacity for each axle system. The GAWR is
specific to each vehicle and is listed on the Safety
Certification Label on the driver’s door pillar.
•GCW (Gross Combined Weight):The
combined weight of the towing vehicle (including
occupants and cargo) and the loaded trailer.
•GCWR (Gross Combined Weight Rating):
Maximum permissible combined weight of towing
vehicle (including occupants and cargo) and the
loaded trailer
•Maximum Trailer Weight Rating:Maximum
weight of a trailer the vehicle is permitted to tow.
The maximum trailer weight rating is determined
by subtracting the vehicle curb weight for each
engine/transmission combination, any required
option weight for trailer towing and the weight of
the driver from the GCWR for the towing vehicle.
•Maximum Trailer Weight:Maximum weight of a
trailer the loaded vehicle (including occupants

FUEL PUMP SHUT-OFF SWITCH
FUEL
RESET
The fuel pump shut-off switch is a device intended
to stop the electric fuel pump when your vehicle has
been involved in a substantial jolt.
After a collision, if the engine cranks but does not
start, the fuel pump shut-off switch may have been
activated.
The fuel pump shut-off
switch is located on the
left side of the trunk
between the left rear
tail light and the trunk
liner, and to the left of
the hole in the trunk
liner. If you are unable
to access the switch
through the hole, loosen the trunk liner near the
switch by removing the cargo net hook and pulling
the liner forward to expose the switch.
Use the following procedure to reset the fuel pump
shut-off switch.
1. Turn the ignition to the OFF position.
2. Check the fuel system for leaks.
3. If no fuel leak is apparent, reset the fuel pump
shut-off switch by pushing in on the reset button.
4. Turn the ignition to the ON position. Pause for a
few seconds and return the key to the OFF position.
5. Make a further check for leaks in the fuel system.

If the vehicle slips off the jack, you or
someone else could be seriously injured.
1. Park on a level
surface, activate hazard
flashers and set
parking brake.
2. Place gearshift lever
in P (Park) or R (manual transmission), turn engine
OFF, and block the diagonally opposite wheel.
3. Remove the spare
tire, jack and lug
wrench.
4. Remove the center
ornament (if equipped)
from the wheel. Loosen
each wheel lug nut
one-half turn
counterclockwise but
do not remove them
until the wheel is
raised off the ground.
Roadside Emergencies
167

5. Put the jack in the
jack notch next to the
tire you are changing.
Turn the jack handle
clockwise until the
wheel is completely off
the ground.
Never use the rear
differential as a
jacking point.
To lessen the
risk of personal
injury, do not put any
part of your body
under the vehicle
while changing a tire.
Do not start the
engine when your
vehicle is on the jack.
The jack is only
meant for changing
the tire.
6. Remove the lug nuts with the lug wrench.
7. Replace the flat tire with the spare tire, making
sure the valve stem is facing outward. Reinstall lug
nuts until the wheel is snug against the hub. Do not
fully tighten the lug nuts until the wheel has been
lowered.
If you are using the temporary tire, the lug nut
washers will not appear to be flush with the rim.
This is normal only when using the temporary spare
tire.
8. Lower the wheel by turning the jack handle
counterclockwise.

3. Install the lug nut by turning the wrench
clockwise.
JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if
exposed to flames, sparks, or lit cigarettes.
An explosion could result in injury or vehicle
damage.
Batteries contain sulfuric acid which can
burn skin, eyes and clothing, if contacted.
Do not attempt to push-start your vehicle.
Automatic transmissions do not have
push-start capability; also, the catalytic
converter may become damaged.
Preparing your vehicle
When the battery is disconnected or a new battery is
installed, the transmission must relearn its shift
strategy. As a result, the transmission may have firm
and/or soft shifts. This operation is considered
normal and will not affect function or durability of
the transmission. Over time, the adaptive learning
process will fully update transmission operation.
1.Use only a 12–volt supply to start your
vehicle.
2. Do not disconnect the battery of the disabled
vehicle as this could damage the vehicle’s electrical
system.
3. Park the booster vehicle close to the hood of the
disabled vehicle making sure the two vehiclesdo
nottouch. Set the parking brake on both vehicles
and stay clear of the engine cooling fan and other
moving parts.
4. Check all battery terminals and remove any
excessive corrosion before you attach the battery
cables. Ensure the vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect
any electrical surges. Turn all other accessories off.

4. Make the final connection of the negative (-)
cable to an exposed metal part of the stalled
vehicle’s engine, away from the battery and the
carburetor/fuel injection system.Do notuse fuel
lines, engine rocker covers or the intake manifold as
groundingpoints.
Do not connect the end of the second cable
to the negative (-) terminal of the battery to
be jumped. A spark may cause an explosion of the
gases that surround the battery.
5. Ensure that the cables are clear of fan blades,
belts, moving parts of both engines, or any fuel
delivery system parts.
Jump starting
1. Start the engine of the booster vehicle and run
the engine at moderately increased speed.
2. Start the engine of the disabled vehicle.
3. Once the disabled vehicle has been started, run
both engines for an additional three minutes before
disconnecting the jumper cables.
