tire JEEP CHEROKEE LIMITED 2017 User Guide

(Trailhawk only): Avoid driving in standing water deeper
than 19 inches (48 cm), and reduce speed appropriately to
minimize wave effects. Maximum speed in 19 inches (48
cm) of water is less than 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine, transmission, Power Transfer
Unit, and Rear Drive Module) to assure they have not been
contaminated. Contaminated fluids and lubricants (milky,
foamy in appearance) should be flushed/changed as soon
as possible to prevent component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the 4WD system to the appropriate terrain
mode, using 4WD LOW if necessary. Refer to “Four-Wheel
Drive Operation” in “Starting And Operating” for further
information. Do not shift to a lower gear than necessary to
maintain headway. Over-revving the engine can spin the
wheels and traction will be lost.
Avoid abrupt downshifts on icy or slippery roads because
engine braking may cause skidding and loss of control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the 4WD System to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
NOTE: Brakes should be applied at increased slippage, but
before coming to a stop to avoid digging into the loose
surface and rendering the operator of the vehicle stuck/
immobile.
If you stall or begin to lose headway while climbing a
steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Once stopped, shift to
REVERSE. Back slowly down the hill allowing the com-
pression braking of the engine to help regulate your speed.
If the brakes are required to control vehicle speed, apply
them lightly and avoid locking or skidding the tires.

WARNING!(Continued)
to turn around. To do so may result in tipping and
rolling the vehicle. Always back straight down a hill in
REVERSE gear carefully. Never back down a hill in
NEUTRAL using only the brake.
NOTE: Remember, never drive diagonally across a hill -
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 headway by turning
the front wheels slowly left and right. This may provide a
fresh “bite” into the surface and may provide traction to
complete the climb.
Traction Downhill
Shift the transmission into a low gear and the 4WD System
to 4WD LOW range or Select Hill Descent Control if
equipped (refer to Safety Featuresin the “Safety” section
for further information). Let the vehicle go slowly down
the hill with all four wheels turning against engine com-
pression 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.
•
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.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These things
could be a fire hazard. They might hide damage to fuel
lines, brake hoses, axle pinion seals, and propeller shafts.

JACKING AND TIRE CHANGING

4. Remove the fastener securing the jack and spare tire.
5. Remove the chocks.
6. Remove the scissors jack and wheel bolt wrench fromthe spare wheel as an assembly. Turn the jack screw to
the left to loosen the wheel bolt wrench, and remove the
wrench from the jack assembly. NOTE:
The jack handle attaches to the side of the jack with
two attachment points. When the jack is partially ex-
panded, the tension between the two attachment points
holds the jack handle in place.
7. Remove the spare tire.

WARNING!(Continued)
Always stow the jack parts and the spare tire in the
places provided. Have the deflated (flat) tire repaired
or replaced immediately.
Preparations For Jacking
1. Park the vehicle on a firm level surface as far from the
edge of the roadway as possible. Avoid icy or slippery
areas.

IN CASE OF EMERGENCY 391

WARNING!(Continued)
•Do not let anyone sit in the vehicle when it is on a
jack.
• Do not get under the vehicle when it is on a jack. If
you need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
• Only use the jack in the positions indicated and for
lifting this vehicle during a tire change.
• If working on or near a roadway, be extremely
careful of motor traffic.
• To assure that spare tires, flat or inflated, are securely
stowed, spares must be stowed with the valve stem
facing the ground.

5. Raise the vehicle just enough to remove the flat tire.

NOTE:•For vehicles so equipped, do not attempt to install a
center cap or wheel cover on the compact spare.
• Refer to “Compact Spare Tire” and to “Limited-Use
Spare” under “Tires—General Information” in “Servic-
ing And Maintenance” for additional warnings, cau-
tions, and information about the spare tire, its use, and
operation.
9. Install the wheel bolts with the threaded end of the wheel bolt toward the wheel. Lightly tighten the wheel
bolts.

12. Securely stow the jack, tools, chocks, and flat tire.

WARNING!
•Do not attempt to seal a tire on the side of the vehicle
closest to traffic. Pull far enough off the road to avoid
the danger of being hit when using the Tire Service
Kit.
• Do not use Tire Service Kit or drive the vehicle under
the following circumstances:
– If the puncture in the tire tread is approximately 1/4 inch (6 mm) or larger.
– If the tire has any sidewall damage.
– If the tire has any damage from driving with extremely low tire pressure.
– If the tire has any damage from driving on a flat tire.
– If the wheel has any damage.
– If you are unsure of the condition of the tire or the wheel.
• Keep Tire Service Kit away from open flames or heat
source.
• A loose Tire Service Kit thrown forward in a collision
or hard stop could endanger the occupants of the
vehicle. Always stow the Tire Service Kit in the place
