What's the worst time for this? ªWet ice.º Very cold
snow or ice can be slick and hard to drive on. But wet
ice can be even more trouble because it may offer the
least traction of all. You can get wet ice when it's about
freezing (32F; 0C) and freezing rain begins to fall.
Try to avoid driving on wet ice until salt and sand crews
can get there.Whatever the condition
-- smooth ice, packed, blowing
or loose snow
-- drive with caution.
Accelerate gently. Try not to break the fragile traction.
If you accelerate too fast, the drive wheels will spin and
polish the surface under the tires even more.
Your anti
-lock brakes improve your vehicle's stability
when you make a hard stop on a slippery road. Even
though you have an anti
-lock braking system, you'll
want to begin stopping sooner than you would on dry
pavement. See ªAnti
-Lockº in the Index.

Allow greater following distance on any
slippery road.

Watch for slippery spots. The road might be fine
until you hit a spot that's covered with ice. On an
otherwise clear road, ice patches may appear in
shaded areas where the sun can't reach: around
clumps of trees, behind buildings 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're actually on
the ice, and avoid sudden steering maneuvers.

CAUTION:
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 can't 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 your exhaust pipe. And check
around again from time to time to be sure snow
doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will help
keep CO out.
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 signaling 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 uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
Recreational Vehicle Towing
Your vehicle was not designed to be towed with all four
wheels on the ground. If your vehicle must be towed,
see ªTowing Your Vehicleº in the Index.
NOTICE:
Towing your vehicle with all four wheels on the
ground will damage drivetrain components.

5-15 How to Add Coolant to the Radiator
1. You can remove the
radiator pressure cap
when the cooling
system, including the
radiator pressure cap
and upper radiator
hose, is no longer hot.
Turn the pressure cap slowly counterclockwise until
it first stops. (Don't press down while turning the
pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there is still some pressure left.
2. Then keep turning
the pressure cap, but
now push down as
you turn it. Remove
the pressure cap.

Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
CAUTION:
Changing a tire can cause an injury. The vehicle
can slip off the jack and roll over you or other
people. You and they could be badly injured.
Find a level place to change your tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
4. Put the wheel blocks at the front and
rear of the tire farthest away from the
one being changed. That would be the
tire on the other side of the vehicle, at
the opposite end.The following steps will tell you how to use the jack and
change a tire.

5-20 Removing the Spare Tire and Tools
The jacking equipment you'll need is stored by your
vehicle's rear doors, along the passenger's side wall.
Remove your jack cover by pulling it away from the
side wall and down to release the tabs securing the top
of the cover.
Remove the wheel blocks by turning the top nut
counterclockwise. Remove the nut and washer, then pull
the wheel blocks off the bolt. Push down on the bolt and
remove the hooked end from the slot. Slide the jack
toward the front of the vehicle and lift it from the
mounting. Remove the extension and the ratchet from
the pouch.

5-22
Put the flat end of the extension on an angle through the
hole in the rear door frame, above the bumper. Be sure
the flat end connects into the hoist shaft.
Turn the ratchet counterclockwise to lower the spare tire
to the ground. Keep turning the ratchet until the spare
tire can be pulled out from under the vehicle.
When the tire has been
lowered, tilt the retainer
plate at the end of the cable
and pull it through the
wheel opening.
Pull the tire out from under the vehicle.
NOTICE:
To help avoid vehicle damage, do not drive the
vehicle before cable is restored.

5-23
The tools you'll be using include the jack (A), wheel
blocks (B), extension (C) and ratchet (D).
Removing the Wheel Covers
You will have to take off hub caps or wheel nut caps to
reach your wheel nuts.
Styled Steel Wheel Shown
If you have a standard steel wheel, carefully pry along
the edge of the hub cap until it comes off. Be careful, the
rim edges may be sharp. Don't try to remove the hub
cap with your bare hands.
If you have the styled steel wheel or aluminum wheel
with plastic nut caps, loosen the plastic nut caps with the
ratchet and socket. Make sure the DOWN side
faces you.
To remove the hub cap from the aluminum wheel
without plastic nut caps, fit the flat end of the extension
into the notch. Then, remove the center cap.

5-24 Removing the Flat Tire and Installing the
Spare Tire
1. Before you start, block the front and rear of the tire
farthest away from the one being changed. Then put
your spare tire near the flat tire.
2. With the DOWN side facing you, use the ratchet and
socket to loosen all the wheel nuts. Don't remove
them yet.
3. The jack has a bolt on the end. Attach the socket end
of the extension to the jack bolt.
