HAZARD WARNING FLASHER
The Hazard Warning flasher switch is located on the
upper switch bank just below the radio.
Press the switch to turn on the Hazard Warning
flasher. When the switch is activated, all directional
turn signals will flash on and off to warn oncoming
traffic of an emergency. Press the switch a second time to
turn off the Hazard Warning flasher.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flasher will continue to operate even
though the ignition is placed in the OFF position.
NOTE: With extended use the Hazard Warning flasher
may wear down your battery. JACKING AND TIRE CHANGING
WARNING!• Being under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle 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.
• The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.356 WHAT TO DO IN EMERGENCIES

3500 Models — If Equipped
The jack and jack tools are stored under the front
passenger seat. Lift the flap on the side of the seat for
access.
Remove the jack and tools by removing the wing bolt and
sliding the assembly from under the seat. WARNING!After using the jack and tools, always reinstall them
in the original carrier and location. While driving
you may experience abrupt stopping, rapid accelera-
tion, or sharp turns. A loose jack, tools, bracket or
other objects in the vehicle may move around with
force, resulting in serious injury.
4500/5500 Models
These vehicles do not come equipped with a jack.
NOTE: Jacking and tire changing on 4500/5500 models
should be performed by an authorized dealer, or knowl-
edgeable service personnel with the appropriate heavy
duty equipment, like a tire service company.

Preparations For Jacking
1. Park the vehicle on a firm, level surface. Avoid ice or
slippery areas.
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 the danger of being hit when
operating the jack or changing the wheel.
2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Place the shift lever into PARK (automatic transmis-
sion) or REVERSE (manual transmission). On 4-Wheel
drive vehicles, shift the transfer case to the “4L” position.
5. Turn OFF the ignition. 6. Block both the front and rear of the
wheel diagonally opposite the jacking
position. For example, if the right front
wheel is being changed, block the left
rear wheel.
NOTE: Passengers should not remain in the vehicle
when the vehicle is being jacked.
