Steering - Buick LaCrosse 2011 Owner's Manual

9-4 Driving and Operating
And, of course, actual stopping
distances vary greatly with the
surface of the road, whether it is
pavement or gravel; the condition
of the road, whether it is wet, dry,
or icy; tire tread; the condition of the
brakes; the weight of the vehicle;
and the amount of brake force
applied.
Avoid needless heavy
braking. Some people drive in
spurts heavy acceleration
followed by heavy braking
than keeping pace with traffic.
This is a mistake. The brakes
might not have time to cool
between hard stops. The brakes
will wear out much faster with a
lot of heavy braking. Keeping pace
with the traffic and allowing realistic
following distances eliminates a lot
of unnecessary braking. That means
better braking and longer brake life.
If the engine ever stops while
the vehicle is being driven, brake
normally but do not pump the
brakes. If the brakes are pumped,
the pedal could get harder to push
down. If the engine stops, there
will still be some power brake assist
but it will be used when the brake
is applied. Once the power assist is
used up, it can take longer to stop
and the brake pedal will be harder
to push.
rather Adding non dealer accessories
can affect vehicle performance.

Power Steering
If power steering assist is lost
because the engine stops or the
power steering system is not
functioning, the vehicle can be
steered but it will take more effort.

Speed Variable Assist Steering
The vehicle has a steering system
that varies the amount of effort
required to steer the vehicle in
relation to the speed of the vehicle.
The amount of steering effort
required is less at slower
speeds to make the vehicle more
maneuverable and easier to park.
At faster speeds, the steering effort
increases to provide a sport-like
feel to the steering. This provides
maximum control and stability.
If the vehicle seems harder to steer
than normal when parking or driving
slowly, there may be a problem
with the system. You will still have
power steering, but steering will be
stiffer than normal at slow speeds.
