replacement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Requirements – Trailer Brakes

Donot interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
An electronically actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers over
1,000 lbs (454 kg) and required for trailers in excess of
2,000 lbs (907 kg).
CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
•Do not connect trailer brakes to your vehicle’s
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have an
accident.
•Towing any trailer will increase your stopping dis-
tance. When towing you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.

Towing Requirements – Trailer Lights and Wiring
Your authorized dealer offers a trailer wiring harness
designed specifically for your vehicle.
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-
pin wiring harness. Use a factory approved trailer har-
ness and connector.
NOTE:Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations.

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
Automatic Transaxle
The automatic transaxle fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. Refer to “Mainte-
nance Schedule” for the proper maintenance intervals.

result. If these vehicles require towing, make sure
all four wheels are off the ground.

AUTOMATIC TRANSAXLE OVERHEATING
During sustained high speed driving or trailer towing up
long grades on hot days, the automatic transaxle oil may
become too hot.If this happens, the transmission overheat in-
dicator light will come on, and the vehicle will
slow slightly until the automatic transaxle
cools down enough to allow a return to the
requested speed. If the high speed is maintained, the
overheating will reoccur, as before, in a cyclic fashion.
JACKING AND TIRE CHANGING
WARNING!
•Being under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle is on a jack. If you
need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
•The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.
360 WHAT TO DO IN EMERGENCIES

Jack Location
The jack and jack-handle are stowed under the load floor
in the cargo area.
Spare Tire Stowage
The compact spare tire is stowed under the rear load floor
in the cargo area.
Spare Tire Removal
Lift up the load floor cover and remove the hold down.
Preparations For Jacking
1. Park the vehicle on a firm level surface, avoiding ice or
slippery areas.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
2. Set the parking brake.
3. Place the shift lever in PARK (automatic transaxle) or
REVERSE (manual transaxle).
4. Turn OFF the ignition.

WHAT TO DO IN EMERGENCIES 361

WARNING! (Continued)
•If working on or near a roadway, be extremely
careful of motor traffic.
•To assure that spare tires, flat or inflated, are
securely stowed, spares must be stowed with the
valve stem facing the ground.
•Turn on the Hazard Warning flasher.
1. Remove the scissors jack and lug wrench from the
spare wheel as an assembly. Turn the jack screw to the left
to loosen the lug wrench and remove the wrench from
the jack assembly. 2. Loosen, but do not remove, the wheel nuts by turning
them to the left one turn while the wheel is still on the
ground.
Jack Warning LabelJacking Locations

WHAT TO DO IN EMERGENCIES 363

CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in Step 3.
3. There are two front jacking locations and two rear
jacking locations on each side of the body. The front
locations are outlined by two triangular cutouts, the rear
ones by two rectangular cutouts. For vehicles equipped
with plastic trim, the plastic has been cut away to expose
the jacking locations in the body.
Do not raise the vehicle until you are sure the jack is
securely engaged.
4. Turn the jack screw to the left until the jack can be
placed under the jacking location. Once the jack is
positioned, turn the jack screw to the right until the jack
head is properly engaged with the lift area closest to the
wheel to be changed.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable. It could slip off the jack and
hurt someone near it. Raise the vehicle only enough
to remove the tire.
5. Using the swivel wrench raise the vehicle by turning
the jack screw to the right. Raise the vehicle only until the
tire just clears the surface and enough clearance is
obtained to install the spare tire. Minimum tire lift
provides maximum stability.
6. Remove the wheel nuts and pull the wheel and wheel
covers, where applicable, off the hub. Install the spare
wheel and wheel nuts with the cone shaped end of the
nuts toward the wheel. Lightly tighten the nuts. To avoid
the risk of forcing the vehicle off the jack, do not tighten
the nuts fully until the vehicle has been lowered.
364 WHAT TO DO IN EMERGENCIES

WARNING!
To avoid possible personal injury, handle the wheel
covers with care to avoid contact with any sharp
edges.
NOTE: The wheel cover is held on the wheel by the
wheel nuts. When reinstalling the original wheel, prop-
erly align the wheel cover to the valve stem, place the
wheel cover onto the wheel, then install the wheel nuts.
7. Lower the vehicle by turning the jack screw to the left.
8. Finish tightening the nuts. Push down on the wrench
while tightening the wheel nuts. Alternate nuts until each
nut has been tightened twice. The correct wheel nut
torque is 100 ft lbs (135 N·m). If you doubt that you have
tightened the nuts correctly, have them checked with a
torque wrench by your authorized dealer or service
station. 9. Remove the wheel blocks and lower the jack until it is
free. Reassemble the lug wrench to the jack assembly and
stow it in the spare tire area. Secure the assembly using
the means provided.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
10. Place the deflated (flat) tire in the cargo area, have the
tire repaired or replaced as soon as possible.
WARNING!
A loose tire thrown forward in a collision or hard stop
could injure the occupants in the vehicle. Have the
deflated (flat) tire repaired or replaced immediately.
