2017 JEEP GRAND CHEROKEE lock

speed, apply them lightly and avoid locking or skidding
the tires.
WARNING!
If the engine stalls, you lose forward motion, or cannot
make it to the top of a steep hill or grade, never attempt
to turn around. To do so may result in tipping and
rolling the vehicle. Always back carefully straight
down a hill in REVERSE gear. Never back down a hill
in NEUTRAL using only the brake.
Remember, never drive diagonally across a hill always
drive straight up or down.
If the wheels start to slip as you approach the crest of a hill,
ease off the accelerator and maintain forward motion by
turning the front wheels slowly. This may provide a fresh
“bite” into the surface and will usually provide traction to
complete the climb.
Traction Downhill
When descending mountains or hills, use Hill Descent or
Selec-Speed Control to avoid repeated heavy braking. If not equipped with Hill Descent or Selec-Speed Control
use the following procedure:
Shift the transmission into a low gear, and the transfer case
into 4WD LOW range. Let the vehicle go slowly down the
hill with all four wheels turning against engine compres-
sion drag. This will permit you to control the vehicle speed
and direction.
When descending mountains or hills, repeated braking can
cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmission
whenever possible.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage. That way you can
get any problems taken care of right away and have your
vehicle ready when you need it.
•
Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required.
394 STARTING AND OPERATING

Bulb Replacement
High Intensity Discharge Headlamps (HID) — If
Equipped
The headlamps are a type of high voltage discharge tube.
High voltage can remain in the circuit even with the
headlamp switch off and the key removed.Because of this,
you should not attempt to service a headlamp bulb
yourself. If a headlamp bulb fails, take your vehicle to an
authorized dealer for service.
WARNING!
A transient high voltage occurs at the bulb sockets of
High Intensity Discharge (HID) headlamps when the
headlamp switch is turned ON. It may cause serious
electrical shock or electrocution if not serviced prop-
erly. See your authorized dealer for service.
NOTE: On vehicles equipped with High Intensity Dis-
charge (HID) headlamps, when the headlamps are turned
on, there is a blue hue to the lamps. This diminishes and
becomes more white after approximately 10 seconds, as the
system charges.
Halogen Headlamps — If Equipped
1. Open the hood.
2. Turn the low or high beam bulb one–quarter turn counterclockwise to remove from housing.
3. Disconnect the electrical connector and replace the bulb.
CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the
bulb comes in contact with any oily surface, clean the
bulb with rubbing alcohol.
