2012 JEEP GRAND CHEROKEE torque

6. Raise the vehicle by turning the jack screw
clockwise. Raise the vehicle only until the tire
just clears the surface and enough clearance is
obtained to install the spare tire. Minimum tire
lift provides maximum stability.
WARNING!
Raising the vehicle higher than necessary can
make the vehicle less stable. It could slip off
the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
7. Remove the lug nuts and wheel. 8. Position the spare wheel/tire on the vehicle
and install the lug nuts with the cone-shaped
end toward the wheel. Lightly tighten the nuts.
CAUTION!
Be sure to mount the spare tire with the valve
stem facing outward. The vehicle could be
damaged if the spare tire is mounted incor-
rectly.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the wheel nuts fully until
the vehicle has been lowered. Failure to follow
this warning may result in personal injury.
9. Lower the vehicle by turning the jack screw
counterclockwise, and remove the jack and
wheel blocks.
10. Finish tightening the lug nuts. Push down
on the wrench while at the end of the handle for
increased leverage. Tighten the lug nuts in a
star pattern until each nut has been tightened
twice. The correct wheel nut tightness is 110 ft
lbs (150 N·m). If in doubt about the correct
tightness, have them checked with a torque
wrench by your authorized dealer or at a ser-
vice station.
11. Lower the jack to the fully closed position
and return it and the tools to the proper posi-
tions in the foam tray.
12. Remove the small center cap and securely
store the road wheel in the cargo area.

13. Have the aluminum road wheel and tire
repaired as soon as possible, properly secure
the spare tire with the special wing nut torqued
to 3.7 ft-lbs (5 N·m), reinstall the jack and tool
kit foam tray, and latch the rear load floor cover.
WARNING!
A loose tire or jack, thrown forward in a
collision or hard stop could endanger the
occupants of the vehicle. Always stow the jack
parts and the spare tire in the places provided.
Have the deflated (flat) tire repaired or re-
placed immediately.
Road Tire Installation
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the cone
shaped end of the nut toward the wheel. Lightly
tighten the lug nuts.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the wheel nuts fully until
the vehicle has been lowered. Failure to follow
this warning may result in personal injury.
3. Lower the vehicle to the ground by turning
the jack handle counterclockwise.
4. Finish tightening the lug nuts. Push down on
the wrench while at the end of the handle for
increased leverage. Tighten the lug nuts in a
star pattern until each nut has been tightened
twice. The correct tightness of each lug nut is
110 ft/lbs (150 N·m). If in doubt about the
correct tightness, have them checked with a
torque wrench by your authorized dealer or
service station. 5. After 25 miles (40 km) check the lug nut
torque with a torque wrench to ensure that all
lug nuts are properly seated against the wheel.
JUMP-STARTINGIf your vehicle has a discharged battery it can
be jump-started using a set of jumper cables
and a battery in another vehicle or by using a
portable battery booster pack. Jump-starting
can be dangerous if done improperly so please
follow the procedures in this section carefully.
NOTE:
When using a portable battery booster pack
follow the manufacturer’s operating instruc-
tions and precautions.
CAUTION!
Do not use a portable battery booster pack or
any other booster source with a system volt-
age greater than 12 Volts or damage to the
battery, starter motor, alternator or electrical
system may occur.

Front Axle Fluid Level Check
The front axle oil level needs to be between
1/8 in (3 mm) below the bottom of the fill hole
and the bottom of the fill hole.
The front axle fill and drain plugs should be
tightened to 22 to 29 ft lbs (30 to 40 N·m).
CAUTION!
Do not over tighten the plugs as it could
damage them and cause them to leak.
Rear Axle Fluid Level Check
The rear axle oil level needs to be between
1/8 in (3 mm) below the bottom of the fill hole
and the bottom of the fill hole.
The rear axle fill and drain plugs should be
tightened to 22 to 29 ft lbs (30 to 40 N·m) on
axles with aluminum housings. The rear axle fill
and drain plugs should be tightened to 22 to
52 ft lbs (30 to 70 N·m) on axles with cast iron
housings.
CAUTION!
Do not over tighten the plugs as it could
damage then and cause them to leak.
Selection Of Lubricant
Use only the manufacturer’s recommended
fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
Transfer Case
Fluid Level Check
Inspect the transfer case for fluid leaks. If a fluid
leak is found, the transfer case fluid level can
be checked by removing the filler plug located
on the back side of the transfer case. The fluid
level should be at the bottom edge of the filler
plug hole when the vehicle is in a level position.
Adding Fluid
Add fluid at the filler hole, until it runs out of the
hole, when the vehicle is in a level position. Drain
First remove fill plug, then remove drain plug.
Recommended tightening torque for drain and
fill plugs is 15 to 25 ft lbs (20 to 34 N·m).
CAUTION!
When installing plugs, do not overtighten. You
could damage them and cause them to leak.
Selection Of Lubricant
Use only the manufacturer’s recommended
fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
Automatic Transmission
Selection Of Lubricant
It is important that the proper lubricant is used
in the transmission to assure optimum transmis-
sion performance. Use only the manufacturer’s
recommended transmission fluid. Refer to “Flu-
ids, Lubricants, and Genuine Parts” in “Main-
taining Your Vehicle” for further information. It is
important that the transmission fluid be main-
tained at the prescribed level using the recom-
mended fluid. 313

CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may
cause deterioration in transmission shift qual-
ity and/or torque converter shudder. Using a
transmission fluid other than the manufactur-
er’s recommended fluid will require more fre-
quent fluid and filter changes. Refer to “Fluids,
Lubricants, and Genuine Parts” in “Maintain-
ing Your Vehicle” for further information.
Special Additives
Automatic Transmission Fluid (ATF) is an engi-
neered product and its performance may be
impaired by supplemental additives. Therefore,
do not add any fluid additives to the transmis-
sion. The only exception to this policy is the use
of special dyes to aid in detecting fluid leaks. In
addition, avoid using transmission sealers as
they may adversely affect seals.CAUTION!
Do not use chemical flushes in your transmis-
sion as the chemicals can damage your trans-
mission components. Such damage is not
covered by the New Vehicle Limited Warranty.
Fluid Level Check – 3.6L And 3.0L Diesel
Engine
Routine fluid level checks are not required. For
this reason, the dipstick is omitted. Your autho-
rized dealer can check your transmission fluid
level using a special service dipstick.
If you notice fluid leakage or transmission mal-
function, have your authorized dealer check
the transmission fluid level. Operation with an
improper fluid level can greatly reduce the life
of your transmission.CAUTION!
• Using a transmission fluid other than the
manufacturer’s recommended fluid may
cause deterioration in transmission shift
quality and/or torque converter shudder.
Using a transmission fluid other than that
recommended by the manufacturer will re-
quire more frequent fluid and filter changes.
Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for fur-
ther information.
• The fluid level is preset at the factory and it
does not require adjustment under normal
operating conditions. If a transmission fluid
leak occurs, visit your authorized dealer
immediately. Severe damage to the trans-
mission may occur. Your authorized dealer
has the proper tools to adjust the fluid level
accurately.
