Steering - GMC Acadia Denali 2015 Owner's Manual

9-4 Driving and Operating
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.

Steering

Variable Effort Steering
Some vehicles have 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. See
your dealer for service.
Hydraulic Power Steering
This vehicle has hydraulic power
steering. It may require
maintenance. See Power Steering
Fluid on page 10-18.
If power steering assist is lost
because the engine stops, or there
is a system malfunction, the vehicle
can be steered but may require
increased effort. See your dealer if
there is a problem.
Caution
If the steering wheel is turned
until it reaches the end of its
travel, and is held in that position
for more than 15 seconds,
Caution (Continued)
damage may occur to the power
steering system and there may be
loss of power steering assist.
Curve Tips
Take curves at a reasonable
speed.
Reduce speed before entering
a curve.
Maintain a reasonable, steady
speed through the curve.
Wait until the vehicle is out of
the curve before accelerating
gently into the straightaway.
Steering in Emergencies
There are some situations when
steering around a problem may
be more effective than braking.
Holding both sides of the
steering wheel allows you to turn
180 degrees without removing
