Floor Mat Safety Information
Always use floor mats designed to fit your vehicle. Only use
a floor mat that does not interfere with the operation of the
accelerator, brake or clutch pedals. Only use a floor mat that
is securely attached using the floor mat fasteners so it cannot
slip out of position and interfere with the accelerator, brake
or clutch pedals or impair safe operation of your vehicle in
other ways.
WARNING!
An improperly attached, damaged, folded, or stacked
floor mat, or damaged floor mat fasteners may cause
your floor mat to interfere with the accelerator, brake, or
clutch pedals and cause a loss of vehicle control. To
prevent SERIOUS INJURY or DEATH:
• ALWAYS securely attach your floor mat using the floor mat fasteners. DO NOT install your floor mat
upside down or turn your floor mat over. Lightly pull to
confirm mat is secured using the floor mat fasteners on
a regular basis.
• ALWAYS REMOVE THE EXISTING FLOOR MAT
FROM THE VEHICLE before installing any other
floor mat. NEVER install or stack an additional floor
mat on top of an existing floor mat.
• ONLY install floor mats designed to fit your vehicle. NEVER install a floor mat that cannot be properly
attached and secured to your vehicle. If a floor mat
needs to be replaced, only use a FCA approved floor
mat for the specific make, model, and year of your
vehicle.
• ONLY use the driver’s side floor mat on the driver’s side floor area. To check for interference, with the
vehicle properly parked with the engine off, fully
depress the accelerator, the brake, and the clutch pedal
(if present) to check for interference. If your floor mat
interferes with the operation of any pedal, or is not
secure to the floor, remove the floor mat from the
vehicle and place the floor mat in your trunk.
• ONLY use the passenger’s side floor mat on the passenger’s side floor area.
WARNING! (Continued)

252 STARTING AND OPERATING
NOTE:
A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered a normal part of the break-in and not interpreted
as a problem. Please check your oil level with the engine oil
indicator often during the break in period. Add oil as
required.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking brake
is fully applied. Also, be certain to leave the transmission in
PARK.
The foot operated parking brake is located below the lower
left corner of the instrument panel. To apply the park brake,
firmly push the park brake pedal fully. To release the
parking brake, pull the parking brake release handle.Parking Brake Release
When the parking brake is applied with the ignition switch
ON, the “Brake Warning Light” in the instrument cluster
will illuminate.
NOTE:
• When the parking brake is applied and the transmission is placed in gear, the “Brake Warning Light” will flash. If
vehicle speed is detected, a chime will sound to alert the
driver. Fully release the parking brake before attempting
to move the vehicle.
• This light only shows that the parking brake is applied. It does not show the degree of brake application.

354 STARTING AND OPERATING
If you regularly tow a trailer for more than 45 minutes of
continuous operation, then change the automatic transmis-
sion fluid and filter(s) as specified for "police, taxi, fleet, or
frequent trailer towing." Refer to the “Maintenance Plan” for
the proper maintenance intervals.
NOTE:
Check the automatic transmission fluid level before towing
(Six-speed automatic only).
Tow/Haul Mode
To reduce potential for automatic transmission overheating,
activate TOW/HAUL mode when driving in hilly areas, or
select a lower gear range (using the Electronic Range Select
(ERS) shift control) on more severe grades.
Speed Control — If Equipped
• Do not use on hilly terrain or with heavy loads.
• When using the speed control, if you experience speed drops greater than 10 mph (16 km/h), disengage until you
can get back to cruising speed.
• Use speed control in flat terrain and with light loads to maximize fuel efficiency. Cooling System
To reduce potential for engine and transmission over
-
heating, take the following actions:
City Driving
• In city traffic — while stopped, place the transmission in NEUTRAL, but do not increase engine idle speed.
Highway Driving
• Reduce speed.
• Temporarily turn off air conditioning.
Air Suspension System
To aid in attaching/detaching the trailer from the vehicle,
the air suspension system can be used. Refer to “Air Suspen -
sion System” in “Starting And Operating” for further infor -
mation.
NOTE:
The vehicle must remain in the engine running position
while attaching a trailer for proper leveling of the air suspen -
sion system.
