contact
is all you need.

If there is no curb when you’re parking uphill, turn the wheel\
s to the right.
If there is no curb when you’re parking uphill on the left si\
de of a one-way
street, your wheels should be turned to the left.
Torque Lock (Automatic Transmission)
If you are parking on a hill and you don’t shift your transmi\
ssion into P
(Park) properly, the weight of the vehicle may put too much \
force on the
parking pawl in the transmission. You may find
it difficult to pull the shift lever
out of
P (Park). This is called “torque lock.” To prevent torque lock, always
be sure
to shift into P (Park) before you leave the driver’s seat. To find out
how, see “Shifting Into P (Park)” in the Index.
When
you are ready to drive, move the selector lever out of P (Park)
BEFORE you release the parking brake.
If “torque lock” does occur, you may need to have another vehicle push
yours
a little uphill to take some of the pressure from the transmission, so
you can pull the shift lever out of P (Park).

Winter Driving
r
AM480003
Here are some tips for winter driving.
Have your vehicle in good shape for winter. Be sure your engi\
ne coolant
mix is correct.
Snow tires can help in loose snow, but they may give you les\
s traction
on ice than regular tires.
If you do not expect to be driving in deep
snow, but may have to travel over ice, you may not want
to switch to
snow tires at all.
You may want to put winter emergency supplies in your vehicle.
Include
an ice scraper, a small brush or broom, a supply of windshield
washer fluid, a rag, some winter outer clothing, a small shovel, a flashlight, a
red cloth, and a couple of reflective warning triangles. And, if you will be
driiing under severe conditions, include a small bag of sand, a piece of
old
carpet or a couple of burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet the road probably\
have
good traction.
However,
if there is snow or ice between your tires and the road, you can
have a very slippery situation. You’ll have a lot less traction or “grip” and
will
need to be very careful.

What’s the worst time for this? “Wet ice.” 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
(32”F, 0°C) 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 ability to make a hard stop on \
a slippery
road. Even though you have the anti-lock braking system, you’\
ll want to begin
stopping sooner than you would on dry pavement. See “Anti-lo\
ck” in the
Index.
Allow greater following distances on any slippery road.
Watch for slippery spots. The road might be fine until you hi\
t 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 cl\
umps 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.

If You’re Caught in a Blizzard
I-
.
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 o\
n your
hazard flashers. Tie a red cloth to your vehicle
to alert police that you’ve
been stopped by the snow. Put on extra clothing or wrap
a blanket around
you.
If you have no blankets or extra clothing, make body insulators from
newspapers, burlap bags, rags, floor mats-anything you
can wrap around
yourself
or tuck under your clothing to keep warm.
You
can run the engine to keep warm, but be careful.
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
I 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 headlights. Let the heater
run for awhile. 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.
If You’re Stuck in Deep Snow
This manual explains how to get the vehicle out of deep snow without
damaging it. See “Rocking Your Vehicle” in the Index.
Towing a mailer
I A If you don’t use the correct equipment 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.

epairs not covered by your warranty. To pull a trailer correctly, follow the
Every vehicle is ready for some trailer towing,
If it was built with trailering
options, as many are, it’s ready for heavier trailers. But \
trailering is different
than just driving your vehicle by itself. Trailering means changes in handling,
durability, and fuel economy. Successful, safe trailering takes \
correct equipment, and it has to be used properly.
That’s the reason for this section. In
it are many time-tested, important
trailering tips and safety rules. Many of these are important for your safety
and that of your passengers,
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.
e
e
There are many different laws having to do with trailering. Make sure
your rig
will be legal, not only where you live but also where you’ll be\

driving.
A good source for this information can be state or provincial
police.
Consider using sway control with a utility model
if your trailer will weigh
3,000 pounds (1361 kg) or less, or with a wagon model if your trailer
will weigh
4,000 pounds (1800 kg) or less. You should always use sway
control with a utility model
if your trailer will weigh more than 3,000
pounds (1 361 kg), or with a wagon model if your trailer will weigh more
than
4,000 pounds (1800 kg). You can ask a hitch dealer about sway
controls.
Don’t 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.
Then, during the first
500 miles (800 km) that you tow a trailer, don’t
drive over
50 mph (80 kmlh) and don’t make starts at full throttle. That
will help your engine and other parts
of your vehicle wear in at the
heavier loads.
