brake rotor JEEP GRAND CHEROKEE 2013 Owner handbook (in English)

•After extended operation in mud, sand, wa-
ter, or similar dirty conditions, have the radia-
tor, fan, brake rotors, wheels, brake linings,
and axle yokes inspected and cleaned as
soon as possible.
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 a colli-
sion. If you have been operating your vehicle
in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driv-
ing 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.
FUEL SAVER TECHNOLOGY
5.7L ENGINE ONLY – IF
EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine’s eight cylinders
during light load and cruise conditions. The
system is automatic with no driver inputs or
additional driving skills required.
NOTE:
This system may take some time to return to
full functionality after a battery disconnect.
POWER STEERING
3.6L And 5.7L EngineThe 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 inter-
rupted, it will still be possible to steer your
vehicle. Under these conditions, you will ob-
serve a substantial increase in steering effort,
especially at very low vehicle speeds and dur-
ing parking maneuvers.
NOTE:
•
Increased noise levels at the end of the
steering wheel travel are considered nor-
mal 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.

WARNING!(Continued)
•HSA is not a parking brake. If you stop the
vehicle on a hill without putting the trans-
mission in PARK and using the parking
brake, it will roll down the hill and could
cause a collision with another vehicle or
object. Always remember to use the park-
ing brake while parking on a hill, and that
the driver is responsible for braking the
vehicle.
HSA Off
If you wish to turn off the HSA system, it can be
done using the Customer Programmable Fea-
tures in the Electronic Vehicle Information Cen-
ter (EVIC). Refer to “Electronic Vehicle Informa-
tion Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
Ready Alert BrakingReady Alert Braking may reduce the time re-
quired to reach full braking during emergency
braking situations. It anticipates when an emer-
gency braking situation may occur by monitor-
ing how fast the throttle is released by the driver.
When the throttle is released very quickly,
Ready Alert Braking applies a small amount of
brake pressure. This brake pressure will not be
noticed by the driver. The brake system uses
this brake pressure to allow a fast brake re-
sponse if the driver applies the brakes.
Rain Brake SupportRain Brake Support may improve braking per-
formance in wet conditions. It will periodically
apply a small amount of brake pressure to
remove any water buildup on the front brake
rotors. It only functions when the windshield
wipers are in the LO or HI mode, it does not
function in the intermittent mode. When Rain
Brake Support is active, there is no notification
to the driver and no driver interaction is re-
quired.
Hill Descent Control (HDC) —
Four-Wheel Drive Models With MP3023
Two-Speed Transfer Case Only
HDC maintains vehicle speed while descending
hills during off-road driving situations and is
available in 4WD LOW range only. To enable
HDC, press the HDC switch or put the Selec-
Terrain™ system in “ROCK” mode (“ROCK”
mode is only available in 4WD LOW range).
