2017 JEEP WRANGLER torque

WARNING!
Do not disconnect the stabilizer bar and drive on
hard-surfaced roads or at speeds above 18 mph
(29 km/h); you may lose control of the vehicle, which
could result in serious injury. The front stabilizer bar
enhances vehicle stability and is necessary for main-
taining control of the vehicle. The system monitors
vehicle speed and will attempt to reconnect the stabi-
lizer bar at speeds over 18 mph (29 km/h). This is
indicated by a flashing or solid “Sway Bar Indicator
Light.” Once vehicle speed is reduced below 14 mph
(22 km/h), the system will once again attempt to return
to off-road mode.
To disconnect the stabilizer/sway bar, shift to either 4H or
4L and push the SWAY BAR switch to obtain the off-road
position. Refer to “Four-Wheel Drive Operation” in this
section for further information. The “Sway Bar Indicator
Light” will flash until the stabilizer/sway bar has been
fully disconnected. NOTE:
The stabilizer/sway bar may be torque locked due
to left and right suspension height differences. This condi-
tion is due to driving surface differences or vehicle loading.
In order for the stabilizer/sway bar to disconnect/
reconnect, the right and left halves of the bar must be
aligned. This alignment may require that the vehicle be
driven onto level ground or rocked from side to side.
To return to on-road mode, push the SWAY BAR switch
again.
WARNING!
If the stabilizer/sway bar will not return to on-road
mode, the “Sway Bar Indicator Light” will flash in the
instrument cluster and vehicle stability is greatly re-
duced. Do not attempt to drive the vehicle over 18 mph
(29 km/h). Driving faster than 18 mph (29 km/h) may
cause loss of control of the vehicle, which could result
in serious injury. Contact your local authorized dealer
for assistance.

STARTING AND OPERATING 307

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.
• 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.
• After extended operation in mud, sand, water, or similar
dirty conditions, have the radiator, 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 collision. 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.
340 STARTING AND OPERATING

6. Remove the lug nuts and wheel.
7. Position the spare wheel/tire on the vehicle and installthe lug nuts with the cone-shaped end toward the

4. Finish tightening the lug nuts. Push down on thewrench 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. For the correct lug nut
torque refer to “Torque Specifications” in “Technical
Specifications”. 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-STARTING
If 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.
WARNING!
Do not attempt jump-starting if the battery is frozen. It
could rupture or explode and cause personal injury.
CAUTION!
Do not use a portable battery booster pack or any other
booster source with a system voltage greater than 12
Volts or damage to the battery, starter motor, alternator or
electrical system may occur.
NOTE: When using a portable battery booster pack, follow
the manufacturer’s operating instructions and precautions.
358 IN CASE OF EMERGENCY

Transfer Case
Fluid Level Check
The fluid level should be to the bottom edge of the fill hole
(A) 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 the fill plug (B), then the drain plug (C). The
recommended tightening torque for the drain and fill plugs
is 15 to 25 ft lbs (20 to 34 N·m).
CAUTION!
When replacing the plugs, do not overtighten them.
You could damage them and cause them to leak.
Selection Of Lubricant
Use only the manufacturer’s recommended fluid. Refer to
“Fluids And Lubricants” in “Technical Specifications” for
further information.
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer’s specified transmission fluid. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for fluid specifications. It is important to maintain the
transmission fluid at the correct level using the recom-
mended fluid.Transfer Case
402 SERVICING AND MAINTENANCE

NOTE:No chemical flushes should be used in any trans-
mission; only the approved lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufactur-
er ’s recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for fluid specifications.
Special Additives
The manufacturer strongly recommends against using any
special additives in the transmission. Automatic Transmis-
sion Fluid (ATF) is an engineered product and its perfor-
mance may be impaired by supplemental additives. There-
fore, do not add any fluid additives to the transmission.
The only exception to this policy is the use of special dyes
for diagnosing fluid leaks. Avoid using transmission seal-
ers as they may adversely affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New Vehicle
Limited Warranty.
Fluid Level Check
It is best to check the fluid level when the transmission is
at normal operating temperature (approximately 180°F/
82°C). This occurs after at least 15 miles (25 km) of driving.
At normal operating temperature, the fluid cannot be held
comfortably between the fingertips.
Use the following procedure to check the transmission
fluid level properly:
1. Park the vehicle on level ground.
2. Remove the engine cover by pulling it up off the mounting studs (two in the front and two in the rear).
3. Run the engine at normal idle speed for at least 60 seconds, and leave the engine running for the rest of this
procedure.
4. Fully apply the parking brake, and press the brake pedal.

VEHICLE IDENTIFICATION NUMBER
The Vehicle Identification Number (VIN) is found on the
left front corner of the instrument panel pad, visible from
outside of the vehicle through the windshield. This number
also appears underbody, on the right side of the frame rail
near the center of the vehicle, as well as on the Automobile
Information Disclosure Label affixed to a window on your
vehicle. Save this label for a convenient record of your
vehicle identification number and optional equipment.
The VIN is also stamped on either right or left hand side of
the engine block.NOTE:
It is illegal to remove or alter the VIN plate.BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake sys-
tems. If either of the two hydraulic systems loses normal
capability, the remaining system will still function. How-
ever, there will be some loss of overall braking effective-
ness. You may notice increased pedal travel during appli-
cation, greater pedal force required to slow or stop, and
potential activation of the “Brake System Warning Light.”
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off) the brakes
will still function. However, the effort required to brake the
vehicle will be much greater than that required with the
power system operating.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly cali-
brated torque wrench.
