GMC Terrain: Control of a Vehicle. Braking, Steering / Braking
Braking action involves perception
time and reaction time. Deciding to
push the brake pedal is perception
time. Actually doing it is
reaction time.
Average driver reaction time is
about three-quarters of a second. In
that time, a vehicle moving at
100 km/h (60 mph) travels 20m
(66 ft), which could be a lot of
distance in an emergency.
Helpful braking tips to keep in mind
include:
- Keep enough distance between
you and the vehicle in front
of you.
- Avoid needless heavy braking.
- Keep pace with traffic.
If the engine ever stops while the
vehicle is being driven, brake
normally but do not pump the
brakes. Doing so could make the
pedal harder to push down. If the
engine stops, there will 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.
Electric Power Steering
The vehicle has electric power
steering. It does not have power
steering fluid. Regular maintenance
is not required.
If power steering assist is lost due
to a system malfunction, the vehicle
can be steered, but may require
increased effort...
Other information:
This light is part of the vehicle’s
emission control on-board
diagnostic system. If this light is on
while the engine is running, a
malfunction has been detected and
the vehicle may require service. The
light should come on to show that it
is working when the ignition is in
Service Mode...
The ACC front camera can be
affected by poor lighting conditions,
and ACC may have limited
performance when:
There are changes in brightness,
such as entering and exiting
tunnels, bridges, and
overpasses.
Low sun angles cause the
camera to not detect objects,
or it is more difficult to detect
objects in the same traffic lane...
