seats or steering wheel if equipped.
OPERATING TIPS
Refer to the chart at the end of this section for
suggested control settings for various weather
conditions.
Summer Operation
The engine cooling system must be protected with
a high-quality antifreeze coolant to provide proper
corrosion protection and to protect against engine
overheating. OAT coolant (conforming to
MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster
performance, make sure the engine cooling
system is functioning properly and the proper
amount, type, and concentration of coolant is
used. Use of the Air Recirculation mode during
Winter months is not recommended, because it
may cause window fogging.
Vacation/Storage
For information on maintaining the Climate Control
system when the vehicle is being stored for an
extended period of time, see Ú page 260.
Window Fogging
Vehicle windows tend to fog on the inside in mild,
rainy, and/or humid weather. To clear the
windows, select Defrost or Mix mode and increase
the front blower speed. Do not use the
Recirculation mode without A/C for long periods,
as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of
the windshield, is free of obstructions, such as
leaves. Leaves collected in the air intake may
reduce airflow, and if they enter the air distribution
box, they could plug the water drains. In Winter
months, make sure the air intake is clear of ice,
slush, and snow.
Cabin Air Filter
The Climate Control system filters out dust and
pollen from the air. Contact an authorized dealer to
service your cabin air filter, and to have it replaced
when needed.

SAFETY191
PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven
wear patterns. Check for stones, nails, glass, or
other objects lodged in the tread or sidewall.
Inspect the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges. Check the
lug nuts/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
EXHAUST GAS
ALWAYS make sure objects cannot fall or slide
into the driver’s side floor area when the
vehicle is moving. Objects can become
trapped under accelerator, brake, or clutch
pedals and could cause a loss of vehicle
control.
NEVER place any objects under the floor mat
(e.g., towels, keys, etc.). These objects could
change the position of the floor mat and may
cause interference with the accelerator,
brake, or clutch pedals.
If the vehicle carpet has been removed and
re-installed, always properly attach carpet to
the floor and check the floor mat fasteners are
secure to the vehicle carpet. Fully depress
each pedal to check for interference with the
accelerator, brake, or clutch pedals then
re-install the floor mats.
It is recommended to only use mild soap and
water to clean your floor mats. After cleaning,
always check your floor mat has been properly
installed and is secured to your vehicle using
the floor mat fasteners by lightly pulling mat.
WARNING!
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (CO), follow these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/lift -
gate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.

JUMP STARTING PROCEDURE
NOTE:Make sure at all times that unused ends of jumper
cables are not contacting each other or either
vehicle while making connections.
Connecting The Jumper Cables

1. Connect the positive
(+) end of the jumper
cable to the remote positive (+)
post of the
discharged vehicle.

2. Connect the opposite end of the positive (+)
jumper cable to the positive (+) post of the
booster battery.
3. Connect the negative (-) end of the jumper
cable to the negative (-) post of the booster
battery.
4. Connect the opposite end of the negative (-)
jumper cable to the remote negative (-) post
(exposed metallic/unpainted post of the
discharge vehicle) located directly behind the
under-hood fuse box.
WARNING!
Do not allow vehicles to touch each other as this
could establish a ground connection and
personal injury could result.
WARNING!
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 rings,
watch bands and bracelets that could make
an inadvertent electrical contact. You could be
seriously 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.
WARNING!
Failure to follow this jump starting procedure
could result in personal injury or property
damage due to battery explosion.
CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster
vehicle or the discharged vehicle.
WARNING!
Do not connect the jumper 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.

22_LX_OM_EN_USC_t.book Page 202

IN CASE OF EMERGENCY205
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.
MANUAL PARK RELEASE
To move the vehicle in cases where the
transmission will not shift out of PARK (such as a
depleted battery), a Manual Park Release is
available.
Follow these steps to use the Manual Park
Release:

1. Firmly apply the parking brake.

2. Remove the console storage bin to access the
Manual Park Release lever.

Manual Park Release Cover

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.
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!
Always secure your vehicle by fully applying the
parking brake before activating the Manual Park
Release. In addition, you should be seated in the
driver's seat with your foot firmly on the brake
pedal when activating the Manual Park Release.
Activating the Manual Park Release will allow
your vehicle to roll away if it is not secured by the
parking brake, or by proper connection to a tow
vehicle. Activating the Manual Park Release on
an unsecured vehicle could lead to serious
injury or death for those in or around the vehicle.
