WARNING!
A hot engine cooling system is dangerous. You or others could be badly burned by
steam or boiling coolant.
- Transmission Temperature Warning Light
This light indicates that there is excessive transmission fluid temperature that might
occur with severe usage such as trailer towing. If this light turns on, stop the vehicle
and run the engine at idle, with the transmission in NEUTRAL, until the light turns
off. Once the light turns off, you may continue to drive normally.
CAUTION!
Continuous driving with the Transmission Temperature Warning Light illuminated
will eventually cause severe transmission damage or transmission failure.
WARNING!
If you continue operating the vehicle when the Transmission Temperature Warning
Light is illuminated you could cause the fluid to boil over, come in contact with hot
engine or exhaust components and cause a fire.
- High Beam Indicator
Indicates that headlights are on high beam.
- Front Fog Light Indicator
This indicator will illuminate when the front fog lights are on.
- Turn Signal Indicator
The arrows will flash with the exterior turn signals when the turn signal lever is
operated. A tone will chime, and an EVIC message will appear if either turn signal is
left on for more than 1 mile (1.6 km).
NOTE:
If either indicator flashes at a rapid rate, check for a defective outside light bulb.
- Vehicle Security Light
This light will flash rapidly for approximately 15 seconds when the vehicle theft
alarm is arming. The light will flash at a slower speed continuously after the alarm is
set. The security light will also come on for about three seconds when the ignition is
first turned on.
WHAT TO DO IN EMERGENCIES

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the potential for overheating by
taking the appropriate action:
• On the highways — slow down.
• In city traffic — while stopped, shift the transmission to NEUTRAL, but do not
increase engine idle speed.
NOTE:
There are steps that you can take to slow down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the
engine cooling system and turning the A/C off can help remove this heat.
•
You can also turn the temperature control to maximum heat, the mode control to floor
and the blower control to high. This allows the heater core to act as a supplement to
the radiator and aids in removing heat from the engine cooling system.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into the normal range. If the
pointer remains on HOT (H), and you hear continuous chimes, turn the engine off
immediately, and call for service.
WARNING!
You or others can be badly burned by hot engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming from under the hood, do not open
the hood until the radiator has had time to cool. Never try to open a cooling system
pressure cap when the radiator or coolant bottle is hot.
JACKING AND TIRE CHANGING
Run Flat Tires — SRT Only
This vehicle is equipped with “run flat” tires. Run flat tires allow the vehicle to be
driven approximately 50 miles (80km) at 55 mph (88km/h). Tire service should be
obtained to avoid prolonged run flat feature usage.
NOTE:
This vehicle may be equipped with a spare tire. The spare tire must be used for the
rear wheel(s) only. For a flat front tire, move the rear tire to the front and use the spare
tire on the rear.

WARNING!
• When temperatures are below the freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump-starting because the battery could
rupture or explode and cause personal injury. Battery temperature must be
brought above the freezing point before attempting a jump-start.
•
Take care to avoid the radiator cooling fan whenever the hood is raised. It can start
anytime the ignition switch is on. You can be injured by moving fan blades.
• Remove any metal jewelry, such as watch bands or bracelets, that might make
an inadvertent electrical contact. You could be severely injured.
• Batteries contain sulfuric acid that can burn your skin or eyes and generate
hydrogen gas which is flammable and explosive. Keep open flames or sparks
away from the battery.
• Do not allow vehicles to touch each other as this could establish a ground
connection and personal injury could result.
• Failure to follow this procedure could result in personal injury or property
damage due to battery explosion.
• Do not connect the cable to the negative post (-) of the discharged battery. The
resulting electrical spark could cause the battery to explode and could result in
personal injury.
EMERGENCY TOW HOOKS
If your vehicle is equipped with tow hooks, they are mounted in the front and the rear.
NOTE:
For off-road recovery, it is recommended to use both of the front tow hooks to
minimize the risk of damage to the vehicle.
CAUTION!
Tow hooks are for emergency use only, to rescue a vehicle stranded off-road. Do not
use tow hooks for tow truck hookup or highway towing. You could damage your
vehicle. Tow straps are recommended when towing the vehicle; chains may cause
vehicle damage.
WARNING!
• Chains are not recommended for freeing a stuck vehicle. Chains may break,
causing serious injury or death.
• Stand clear of vehicles when pulling with tow hooks. Tow straps may become
disengaged, causing serious injury.

CAUTION!
• Mixing of engine coolant (antifreeze) other than specified Organic Additive
Technology (OAT) engine coolant (antifreeze), may result in engine damage and
may decrease corrosion protection. Organic Additive Technology (OAT) engine
coolant is different and should not be mixed with Hybrid Organic Additive
Technology (HOAT) engine coolant (antifreeze) or any “globally compatible”
coolant (antifreeze). If a non-OAT engine coolant (antifreeze) is introduced into
the cooling system in an emergency, the cooling system will need to be drained,
flushed, and refilled with fresh OAT coolant (conforming to MS-12106), by an
authorized dealer as soon as possible.
• Do not use water alone or alcohol-based engine coolant (antifreeze) products.
Do not use additional rust inhibitors or antirust products, as they may not be
compatible with the radiator engine coolant and may plug the radiator.
• This vehicle has not been designed for use with propylene glycol-based engine
coolant (antifreeze). Use of propylene glycol-based engine coolant (antifreeze)
is not recommended.

MAINTENANCE SCHEDULE — GASOLINE ENGINE
Your vehicle is equipped with an automatic oil change indicator system. The oil
change indicator system will remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change indicator message will
illuminate. This means that service is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or cold ambient temperatures,
and E85 fuel usage will influence when the “Oil Change Required” message is
displayed. Severe Operating Conditions can cause the change oil message to
illuminate as early as 3,500 miles (5,600 km) since last reset. Have your vehicle
serviced as soon as possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator message after completing the
scheduled oil change. If a scheduled oil change is performed by someone other than
your authorized dealer, the message can be reset by referring to the steps described
under “Instrument Cluster Warning Lights” in “What To Do In Emergencies” in this
guide or “Electronic Vehicle Information Center (EVIC)” in “Understanding Your
Instrument Panel” in your Owners Manual on the DVD for further information.
NOTE:
Under no circumstances should oil change intervals exceed 10,000 miles (16,000 km)
or twelve months, whichever comes first.
