2007 JEEP GRAND CHEROKEE parking brake

Preparations For Jacking
Park the vehicle on a firm level surface, avoid ice or
slippery areas,set the parking brakeand place the gear
selector in P (Park). Turn OFF the ignition.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid being hit when operating the jack
or changing the wheel.
•Turn on the Hazard Warning Flasher.
•Block both the front and rear
of the wheel diagonally oppo-
site of the jacking position.For example, if changing the right front tire, block the
left rear wheel.
•Passengers should not remain in the vehicle when the
vehicle is being jacked.
Jacking Instructions
1. Remove the spare tire, jack, and tools from storage.
2. Loosen (but do not remove) the wheel lug nuts by
turning them to the left one turn while the wheel is still
on the ground.
3. Assemble the jack and jacking tools as shown. Connect
jack handle driver (A) to two extensions (B), then to the
lug wrench (C).

2. Park the booster vehicle within cable reach but with-
out letting the vehicles touch. Set the parking brake on
both vehicles, place the transmission in P (Park), and turn
the ignition OFF.
3. Turn off the heater, radio, and all unnecessary electri-
cal loads.
4. Connect one end of a jumper cable to the positive
terminal of the booster battery. Connect the other end of
the same cable to the positive terminal of the discharged
battery.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
1. Remove all metal jewelry such as watch bands or
bracelets which might make an unintended electrical
contact.
2. Park the booster vehicle within cable reach but with-
out letting the vehicles touch. Set the parking brake on
both vehicles, place the transmission in P (Park), and turn
the ignition OFF.
3. Turn off the heater, radio, and all unnecessary electri-
cal loads.
4. Connect one end of a jumper cable to the positive
terminal of the booster battery. Connect the other end of
the same cable to the positive terminal of the discharged
battery.

Check the fluid level while the transmission is at normal
operating temperature. This occurs after at least 15 miles
(25 km) of driving. At normal operating temperature the
fluid cannot be held comfortably between the fingertips.
To check the automatic transmission fluid level properly,
the following procedure must be used:
1. Operate the engine at idle speed and normal operating
temperature.
2. The vehicle must be on level ground.
3. Fully apply the parking brake and press the brake
pedal.
4. Place the gear selector momentarily in each gear
position ending with the lever in P (Park).
5. Remove the dipstick, wipe it clean and reinsert it until
seated.6. Remove the dipstick again and note the fluid level on
both sides. The fluid level should be between the “HOT”
(upper) reference holes on the dipstick at normal operat-
ing temperature. The fluid level is only valid if there is a
solid coating of oil is seen on both sides of the dipstick. If
the fluid is low, add as required into the dipstick tube.Do
not overfill.After adding any quantity of oil through the
oil fill tube, wait a minimum of two (2) minutes for the oil
to fully drain into the transmission before rechecking the
fluid level.
NOTE:If it is necessary to check the transmissionbelow
the operating temperature, the fluid level should be
between the two “COLD” (lower) holes on the dipstick
with the fluid at approximately 70°F (21°C) (room tem-
perature). If the fluid level is correctly established at
room temperature, it should be between the “HOT”
(upper) reference holes when the transmission reaches
180°F (82°C). Remember it is best to check the level at the
normal operating temperature.

CAUTION!
Be aware that if the fluid temperature is below 50°F
(10°C) it may not register on the dipstick. Do not add
fluid until the temperature is elevated enough to
produce an accurate reading.
7. Check for leaks. Release parking brake.
To prevent dirt and water from entering the transmission
after checking or replenishing fluid, make certain that the
dipstick cap is properly reseated. It is normal for the
dipstick cap to spring back slightly from its fully seated
position, as long as its seal remains engaged in the
dipstick tube.
Special Additives
The manufacturer recommends against the addition of
any additives to the transmission. Exception to this
policy is the use of special dyes to aid in detecting fluid
leaks.
Maintenance After Off-Road Driving
After extended operation in mud, sand or water, or
similar dirty conditions, have your brake discs, brake
linings, and axle joints inspected and cleaned as soon as
possible. This will prevent any abrasive material from
causing excessive wear or unpredictable braking action.
After driving off-road, completely inspect the underbody
of your vehicle. Check tires, body structure, steering,
suspension and exhaust system for damage. Check
threaded fasteners for looseness, particularly on the
chassis, drivetrain components, steering and suspension.
Retighten, if required, to torque values specified in the
