2005 BUICK LACROSSE Owner's Manual

{CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have
to do all the work of slowing down. They could
get so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Always
have your engine running and your vehicle in
gear when you go downhill.
Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your
engine and transaxle, and you can climb the
hill better.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Do not swing wide
or cut across the center of the road. Drive at speeds
that let you stay in your own lane.
As you go over the top of a hill, be alert. There
could be something in your lane, like a stalled car or
an accident.
You may see highway signs on mountains that
warn of special problems. Examples are long
grades, passing or no-passing zones, a falling rocks
area, or winding roads. Be alert to these and take
appropriate action.

Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter.
You may want to put winter emergency supplies in
your trunk.
Also seeTires on page 5-52.Include an ice scraper, a small brush or broom, a
supply of windshield washer uid, a rag, some winter
outer clothing, a small shovel, a ashlight, a red
cloth, and a couple of reective warning triangles. And,
if you will be driving 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.
4-24

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
will have a lot less traction, or grip, and will need to be
very careful.
What is 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 leasttraction of all. You can get wet ice when it is 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.
If you have the traction control system (TCS), it
improves your ability to accelerate when driving on a
slippery road. Even though your vehicle has TCS,
you will want to slow down and adjust your driving to
the road conditions. Under certain conditions, you may
want to turn the TCS off, such as when driving
through deep snow and loose gravel, to help maintain
vehicle motion at lower speeds. SeeTraction Control
System (TCS) on page 4-8.
Unless you have the anti-lock braking system (ABS),
you will want to brake very gently, too. If you do
have ABS, seeAnti-Lock Brake System (ABS) on
page 4-6. ABS improves your vehicle’s stability when
you make a hard stop on a slippery road. Whether you
have ABS or not, you will want to begin stopping
sooner than you would on dry pavement. Without ABS,
if you feel your vehicle begin to slide, let up on the
brakes a little. Push the brake pedal down steadily to
get the most traction you can.
4-25

Remember, unless you have ABS, if you brake so hard
that your wheels stop rolling, you will just slide. Brake
so your wheels always keep rolling and you can
still steer.
Whatever your braking system, allow greater
following distance on any slippery road.
Watch for slippery spots. The road might be ne
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 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 are actually on the ice, and
avoid sudden steering maneuvers.
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 ashers.
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, oor 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.
4-26

{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 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 your 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.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.

If Your Vehicle is Stuck in Sand,
Mud, Ice or Snow
In order to free your vehicle when it is stuck, you will
need to spin the wheels, but you do not want to
spin your wheels too fast. The method known as rocking
can help you get out when you are stuck, but you
must use caution.
{CAUTION:
If you let your tires spin at high speed, they
can explode, and you or others could be injured.
And, the transaxle or other parts of the vehicle
can overheat. That could cause an engine
compartment re or other damage. When you
are stuck, spin the wheels as little as possible.
Do not spin the wheels above 35 mph (55 km/h)
as shown on the speedometer.Notice:Spinning your wheels can destroy parts of
your vehicle as well as the tires. If you spin the
wheels too fast while shifting your transaxle back
and forth, you can destroy your transaxle. See
Rocking Your Vehicle to Get It Out on page 4-28.
For information about using tire chains on your vehicle,
seeTire Chains on page 5-66.
Rocking Your Vehicle to Get It Out
First, turn your steering wheel left and right. That
will clear the area around your front wheels. If your
vehicle has traction control, you should turn your traction
control system off. SeeTraction Control System
(TCS) on page 4-8. Then shift back and forth between
REVERSE (R) and a forward gear, spinning the
wheels as little as possible. Release the accelerator
pedal while you shift, and press lightly on the accelerator
pedal when the transaxle is in gear. By slowly spinning
your wheels in the forward and reverse directions,
you will cause a rocking motion that may free your
vehicle. If that does not get you out after a few tries, you
may need to be towed out. If you do need to be
towed out, seeTowing Your Vehicle on page 4-34.

Loading Your Vehicle
It is very important to know how much weight your
vehicle can carry. Two labels on your vehicle show
how much weight it may properly carry, the Tire
and Loading Information label and the Vehicle
Certication label.
{CAUTION:
Do not load your vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR), or either
the maximum front or rear Gross Axle Weight
Rating (GAWR). If you do, parts on your
vehicle can break, and it can change the way
your vehicle handles. These could cause you
to lose control and crash. Also, overloading
can shorten the life of your vehicle.
Tire and Loading Information Label
A vehicle specic Tire and Loading Information label is
attached to the vehicle’s center pillar (B-pillar). With
the driver’s door open, you will nd the label attached
below the door lock post (striker). The tire and
loading information label lists the number of occupant
seating positions (A), and the maximum vehicle capacity
weight (B) in kilograms and pounds.Label Example
4-29

The Tire and Loading Information label also lists the tire
size of the original equipment tires (C) and the
recommended cold tire ination pressures (D). For more
information on tires and ination, seeTires on
page 5-52andInation - Tire Pressure on page 5-58.
There is also important loading information on the
Certication label. It tells you the Gross Vehicle Weight
Rating (GVWR) and the Gross Axle Weight Rating
(GAWR) for the front and rear axle, see “Certication
Label” later in this section.
Steps for Determining Correct Load Limit
1. Locate the statement “The combined weight
of occupants and cargo should never exceed
XXX kg or XXX pounds” on your vehicle’s placard.
2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and
passengers from XXX kilograms or XXX pounds.4. The resulting gure equals the available amount of
cargo and luggage load capacity. For example, if
the “XXX” amount equals 1400 lbs and there will be
ve 150 lb passengers in your vehicle, the amount
of available cargo and luggage load capacity
is 650 lbs (1400−750 (5 x 150) = 650 lbs).
5. Determine the combined weight of luggage and
cargo being loaded on the vehicle. That weight
may not safely exceed the available cargo
and luggage load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer, the load from
your trailer will be transferred to your vehicle.
Consult this manual to determine how this reduces
the available cargo and luggage load capacity
for your vehicle.
If your vehicle can tow a trailer, seeTowing a Trailer on
page 4-35for important information on towing a
trailer, towing safety rules, and trailering tips.
