vehicle has a traction system, you will want
to slow down and adjust your driving to the
road conditions. Under certain conditions,
you may want to turn the traction system
off, such as when driving through deep
snow and loose gravel, to help maintain
vehicle motion at lower speeds. Refer to
“Traction Control System (TCS)” and
“Electronic Stability Control” in this section.
The Anti-Lock Brake System (ABS)
improves your vehicle’s stability when you
make a hard stop on a slippery road. Even
though you have ABS, you will want to
begin stopping sooner than you would on
dry pavement. Refer to “Anti-Lock Brake
System (ABS)” in this section.
Allow greater following distance on any
slippery road.
Watch for slippery spots. The road might
be fine until you hit a spot that is covered
with ice. On an otherwise clear road, ice
patches may appear in shaded areas
where the sun cannot reach, such as
around clumps of trees, behind build-
ings, or under bridges. Sometimes the
surface of a curve or an overpass may
remain icy when the surrounding roads
are clear. If you see a patch of ice ahead
of you, brake before you are on it. Try not
to brake while you are actually on the
ice, and avoid sudden steering maneu-
vers.If You Are Caught in a Blizzard
If you are stopped by heavy snow, you
could be in a serious situation. You should
probably stay with your vehicle unless you
know for sure that you are near help and
you can hike through the snow. Here are
some things to do to summon help and
keep yourself and your passengers safe:
Turn on your hazard flashers.
Tie a red cloth to your vehicle to alert
police that you have been stopped by the
snow.
Put on extra clothing or wrap a blanket
around you. If you do not have blankets
or extra clothing, make body insulators
from newspapers, burlap bags, rags,
floor mats – anything you can wrap
around yourself or tuck under your cloth-
ing to keep warm.

You can run the engine to keep warm, but
be careful.
Run your engine only as long as you must.
This saves fuel. When you run the engine,
make it go a little faster than just idle. That
is, push the accelerator slightly. This uses
less fuel for the heat that you get and it
keeps the battery charged.
You will need a well-charged battery to
restart the vehicle, and possibly for signal-
ing later on with your headlamps. Let the
heater run for a while.
Then, shut the engine off and close the
window almost all the way to preserve the
heat. Start the engine again and repeat
this only when you feel really uncomfort-
WARNING
Snow can trap exhaust gases under
your vehicle. This can cause deadly
CO (carbon monoxide) gas to get
inside. CO could overcome you and
kill you. You cannot see it or smell it,
so you might not know it is in your
vehicle. Clear away snow from
around the base of your vehicle,
especially any that is blocking the
exhaust pipe. And check around
again from time to time to be sure
snow does not collect there.
Open a window just a little on the
side of the vehicle that is away from
the wind. This will help keep CO out.

the ground. It can be towed with car carrier
equipment.Level ControlYour vehicle may have this feature. This
self-adjusting type of level control is fully
automatic and will provide a better leveled
riding position as well as better handling
under a variety of passenger and loading
conditions. The system is activated when
sufficient weight is added to the vehicle,
and will automatically adjust vehicle height
thereafter. A hydraulic pump inside each
rear shock absorber raises the rear of the
vehicle to the proper height, based on
inputs from the road surface, while the
vehicle is being driven. It takes approxi-
mately two miles (3.2 km) of driving for the
leveling to complete, depending on the
road surface conditions.
If the loaded vehicle is not moved for
approximately twelve hours, the leveling
system may bleed down to a lower height.
This can be especially apparent if a trailer
is left attached to a parked vehicle for long
periods of time. The vehicle must be driven
to re-level the vehicle. If a self-equalizing
hitch is being used, the vehicle should be
driven approximately two miles (3.2 km)
with the trailer prior to adjusting (leveling)
the hitch.
Towing a TrailerTo identify the trailering capacity of your
vehicle, you should read the information in
“Weight of the Trailer” that appears later in
this section. Trailering is different than just
driving your vehicle by itself. Trailering
means changes in handling, acceleration,
braking, durability, and fuel economy. Suc-cessful, safe trailering takes correct equip-
ment, and it has to be used properly.
That is the reason for this section. In it are
many time-tested, important trailering tips
and safety rules. Many of these are impor-
tant for your safety and that of your pas-
sengers. So please read this section
carefully before you pull a trailer.
If You Do Decide To Pull A Trailer
If you do, here are some important points:
There are many different laws, including
speed limit restrictions, having to do with
trailering. Make sure your rig will be
legal, not only where you live but also
where you will be driving. A good source
for this information can be state or pro-
vincial police.
Consider using a sway control. Refer to
“Hitches” later in this section.
Do not tow a trailer at all during the first
500 miles (800 km) your new vehicle is
driven. Your engine, axle or other parts
could be damaged.
During the first 500 miles (800 km) that
you tow a trailer, do not drive over 50
mph (80 km/h) and do not make starts at
full throttle. This helps your engine and
other parts of your vehicle wear in at the
heavier loads.
WARNING
If you do not use the correct equip-
ment and drive properly, you can lose
control when you pull a trailer. For
example, if the trailer is too heavy,
the brakes may not work well – or
even at all. You and your passengers
could be seriously injured. Pull a
trailer only if you have followed all
the steps in this section. Ask your
dealer for advice and information
about towing a trailer with your vehi-
cle.
CAUTION
Pulling a trailer improperly can dam-
age your vehicle and result in costly
repairs that would not be covered by
your warranty. Always follow the
instructions in this section and check
with your dealer for more information
about towing a trailer with your vehi-
cle.
4-24 DRIVING YOUR VEHICLE

your rig. Acquaint yourself with the feel of
handling and braking with the added
weight of the trailer. And always keep in
mind that the vehicle you are driving is now
a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check all trailer hitch
parts and attachments, safety chains, elec-
trical connector, lamps, tires and mirror
adjustment. If the trailer has electric
brakes, start your vehicle and trailer mov-
ing and then apply the trailer brake control-
ler by hand to be sure the brakes are
working. This lets you check your electrical
connection at the same time.
During your trip, check occasionally to be
sure that the load is secure, and that the
lamps and any trailer brakes are still work-
ing.
Following Distance
Stay at least twice as far behind the vehicle
ahead as you would when driving your
vehicle without a trailer. This can help you
avoid situations that require heavy braking
and sudden turns.
Passing
You will need more passing distance up
ahead when you are towing a trailer. And,
because you are a good deal longer, you
will need to go much farther beyond the
passed vehicle before you can return to
your lane.Backing Up
Hold the bottom of the steering wheel with
one hand. Then, to move the trailer to the
left, just move that hand to the left. To
move the trailer to the right, move your
hand to the right. Always back up slowly
and, if possible, have someone guide you.
Making Turns
When you are turning with a trailer, make
wider turns than normal. Do this so your
trailer will not strike soft shoulders, curbs,
road signs, trees or other objects. Avoid
jerky or sudden maneuvers. Signal well in
advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to
have extra wiring.
The arrows on your instrument panel will
flash whenever you signal a turn or lane
change. Properly hooked up, the trailer
lamps will also flash, telling other drivers
you are about to turn, change lanes or
stop.When towing a trailer, the arrows on your
instrument panel will flash for turns even if
the bulbs on the trailer are burned out.
Thus, you may think drivers behind you are
seeing your signal when they are not. It’s
important to check occasionally to be sure
the trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you do not shift down, you
might have to use your brakes so much
that they would get hot and no longer work
well.
Parking on Hills
But if you ever have to park your rig on a
hill, do the following:
1) Apply your regular brakes, but do not
shift into PARK (P) yet.
2) Have someone place chocks under the
trailer wheels.
3) When the wheel chocks are in place,
release the regular brakes until the
chocks absorb the load.
CAUTION
Making very sharp turns while traile-
ring could cause the trailer to come
in contact with the vehicle. Your vehi-
cle could be damaged. Avoid making
very sharp turns while trailering.
WARNING
You really should not park your vehi-
cle, with a trailer attached, on a hill. If
something goes wrong, your rig
could start to move. People can be
injured, and both your vehicle and
the trailer can be damaged.
4-25 DRIVING YOUR VEHICLE

4) Reapply the regular brakes. Then apply
your parking brake, and then shift to
PARK (P).
5) Release the regular brakes.
When You Are Ready to Leave After
Parking on a Hill
1) Apply your regular brakes and hold the
pedal down while you do the following:
1. Start your engine.
2. Shift into a gear.
3. Release the parking brake.
2) Let up on the brake pedal.
3) Drive slowly until the trailer is clear of
the chocks.
4) Stop and have someone pick up and
store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often
when you are pulling a trailer. See the
Maintenance Schedule for more on this.
Things that are especially important in
trailer operation are automatic transaxle
fluid, engine oil, belts, cooling system and
brake system. Each of these is covered in
this manual, and the Index will help you
find them quickly. If you are trailering, it is a
good idea to review these sections before
you start your trip.
Check periodically to see that all hitch nuts
and bolts are tight.

If you overfill the tire, release air by push-
ing on the metal stem in the center of the
tire valve. Re-check the tire pressure with
the tire gage.
Be sure to put the valve caps back on the
valve stems. They help prevent leaks by
keeping out dirt and moisture.Tire Pressure Monitor SystemYour vehicle has a Tire Pressure Monitor
System (TPMS). This system uses radio
and sensor technology to check tire pres-
sure levels. TPMS sensors are mounted
onto each tire and wheel assembly, except
for the spare tire. The TPMS sensors mon-
itor the air pressure in your vehicle's tires
and transmit tire pressure readings to a
receiver located in the vehicle.
Low Tire Pressure Warning Light
1198521
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously illu-
minated. This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists.
When the malfunction indicator is illumi-
nated, the system may not be able to
detect or signal low tire pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction tell-
tale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
WARNING
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If
your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for
those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the
tire to overheat and can lead to tire
failure. Under-inflation also reduces
fuel efficiency and tire tread life, and
may affect the vehicle’s handling and
stopping ability.
(Continued)
WARNING
(Continued)
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tire
pressure, even if under-inflation has
not reached the level to trigger illumi-
nation of the TPMS low tire pressure
telltale.

deep tread, winter-type snow tires, space-
saver, or temporary use spare tires, tires
with nominal rim diameters of 10 to 12
inches (25 to 30 cm), or, to some limited-
production tires.
While the tires available may vary with
respect to these grades, they must also
conform to federal safety requirements.
Treadwear
The treadwear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For
example, a tire graded 150 would wear
one and a half (1.5) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly from
the norm due to variations in driving habits,
service practices, and differences in road
characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to low-
est, are AA, A, B, and C. Those grades
represent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mance.Temperature – A, B, C
The temperature grades are A (the high-
est), B, and C, representing the tire’s resis-
tance to the generation of heat and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel. Sustained high tem-
perature can cause the material of the tire
to degenerate and reduce tire life, and
excessive temperature can lead to sudden
tire failure. The grade C corresponds to a
level of performance which all passenger
car tires must meet under the Federal
Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
Wheel Alignment and Tire BalanceThe tires and wheels on your vehicle were
aligned and balanced carefully at the fac-
tory to give you the longest tire life and
best overall performance. Adjustments to
wheel alignment and tire balancing will not
be necessary on a regular basis. However,
if you notice unusual tire wear or your vehi-
cle pulling to one side or the other, the
alignment may need to be checked. If you
notice your vehicle vibrating when driving
on a smooth road, your tires and wheels
may need to be rebalanced. See your
dealer for proper diagnosis.
WARNING
The traction grade assigned to this
tire is based on straight-ahead brak-
ing traction tests, and does not
include acceleration, cornering,
hydroplaning, or peak traction char-
acteristics.
WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Exces-
sive speed, underinflation, or exces-
sive loading, either separately or in
combination, can cause heat buildup
and possible tire failure.

Wheel ReplacementReplace any wheel that is bent, cracked,
or badly rusted or corroded. If wheel nuts
keep coming loose, the wheel, wheel bolts,
and wheel nuts should be replaced. If the
wheel leaks air, replace it (except some
aluminum wheels, which can sometimes
be repaired). See your dealer if any of
these conditions exist.
Your dealer will know the kind of wheel you
need.
Each new wheel should have the same
load-carrying capacity, diameter, width,
offset, and be mounted the same way as
the one it replaces.
If you need to replace any of your wheels,
wheel bolts or wheel nuts, replace them
only with new original equipment parts.
This way, you will be sure to have the right
wheel, wheel bolts, and wheel nuts for
your vehicle.Refer to “Changing a Flat Tire” in this sec-
tion for more information.
Used Replacement Wheels
Tire Chains
If a Tire Goes FlatIt is unusual for a tire to blowout while you
are driving, especially if you maintain your
vehicle’s 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 blow-
out, here are a few tips about what to
expect and what to do:
WARNING
Using the wrong replacement wheels,
wheel bolts, or wheel nuts on your
vehicle can be dangerous. It could
affect the braking and handling of
your vehicle, make your tires lose air
and make you lose control. You
could have a collision in which you
or others could be injured. Always
use the correct wheel, wheel bolts,
and wheel nuts for replacement.
CAUTION
The wrong wheel can also cause
problems with bearing life, brake
cooling, speedometer or odometer
calibration, headlamp aim, bumper
height, vehicle ground clearance, and
tire or tire chain clearance to the
body and chassis.
WARNING
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 original
equipment wheel.
WARNING
Do not use tire chains. There is not
enough clearance. Tire chains used
on a vehicle without the proper
amount of clearance can cause dam-
age to the brakes, suspension or
other vehicle parts. The area dam-
aged by the tire chains could cause
you to lose control of your vehicle
and you or others may be injured in a
crash.
Use another type of traction device
only if its manufacturer recommends
it for use on your vehicle and tire size
combination and road conditions.
Follow that manufacturer’s instruc-
tions. To help avoid damage to your
vehicle, drive slowly, readjust or
remove the device if it is contacting
your vehicle, and do not spin your
vehicle’s wheels. If you do find trac-
tion devices that will fit, install them
on the front tires.
