Cleaning The Rear Park Assist
Clean the Rear Park Assist Sensors with water, car wash
soap and a soft cloth. Do not use rough or hard cloths. Do
not scratch or poke the sensors. Otherwise, you could
damage the sensors.
REAR CAMERA — IF EQUIPPED
Vehicles with a uconnecttunes radio may be equipped
with a rearview camera (located on the rear liftgate) that
allows you to see an on-screen image (on the navigation
radio screen) of the rear of your vehicle, whenever the
vehicle is put into REVERSE.
WARNING!
Drivers must be careful when backing up even when
using the Rear Camera System. Always check care-
fully behind your vehicle, and be sure to check for
pedestrians, animals, other vehicles, obstructions, or
blind spots before backing up. You are responsible
for the safety of your surroundings and must con-
tinue to pay attention while backing up. Failure to do
so can result in serious injury or death.
CAUTION!
•To avoid vehicle damage, the Rear Camera system
should only be used as a parking aid. The Rear
Camera system is unable to view every obstacle or
object in your drive path.

276 STARTING AND OPERATING

WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent an accident. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
•If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:Increased noise levels at the end of the steering
wheel travel are considered normal and do not indicate
that there is a problem with the power steering system.
Upon initial start-up in cold weather, the power steering
pump may make noise for a short amount of time. This is
due to the cold, thick fluid in the steering system. This
noise should be considered normal, and it does not in any
way damage the steering system.
