WARNING! (Continued)• Always make sure that objects cannot fall into the
driver footwell while the vehicle is moving. Ob-
jects can become trapped under the brake pedal
and accelerator pedal causing a loss of vehicle
control.
• If required, mounting posts must be properly
installed, if not equipped from the factory.
Failure to properly follow floor mat installation or
mounting can cause interference with the brake
pedal and accelerator pedal operation causing loss
of control of the vehicle.
Periodic Safety Checks You Should Make 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 wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately. 2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 81

WARNING!• Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
• Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
• Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and leave you
stranded.
• Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you. POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:
• Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
• Upon initial start-up in cold weather, the power steer-
ing pump may make noise for a short amount of time.
This is due to the cold, thick fluid in the steering302 STARTING AND OPERATING
Page 305 of 502

system. This noise should be considered normal, and it
does not in any way damage the steering system.
WARNING!Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.
Power Steering Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through an autho-
rized dealer.
CAUTION!Do not use chemical flushes in your power steering
system as the chemicals can damage your power
steering components. Such damage is not covered by
the New Vehicle Limited Warranty.
WARNING!Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to ensure accurate fluid level reading. Do
not overfill. Use only manufacturer’s recommended
power steering fluid.
5 STARTING AND OPERATING 303
Page 308 of 502

CAUTION!If the “Brake Warning Light” remains on with the
parking brake released, a brake system malfunction
is indicated. Have the brake system serviced by an
authorized dealer immediately.
BRAKE SYSTEM
If power assist is lost for any reason (for example,
repeated brake applications with the engine off), the
brakes will still function. However, you will experience a
substantial increase in braking effort to stop the vehicle. If either the front or rear hydraulic system loses normal
braking capability, the remaining system will still func-
tion with some loss of overall braking effectiveness. This
will be evident by increased pedal travel during applica-
tion, greater pedal force required to slow or stop, and
activation of the “Brake Warning Light” and the “ABS
Warning Light” (if equipped) during brake use.
The brake system power assist is provided by a hydro-
boost unit which shares fluid with the power steering
system. You may experience some clicking or hissing
noises from the hydro-boost system during hard braking
conditions.
NOTE: Under cold temperatures, pedal effort will be
higher than normal until the power steering fluid reaches
operating temperature.306 STARTING AND OPERATING

CAUTION! (Continued)• Your vehicle has been built with improved fluids
that protect the performance and durability of
your vehicle and also allow extended maintenance
intervals. Do not use chemical flushes in these
components as the chemicals can damage your
engine, transmission, power steering or air condi-
tioning. Such damage is not covered by the New
Vehicle Limited Warranty. If a flush is needed
because of component malfunction, use only the
specified fluid for the flushing procedure.
Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals, such as every fuel stop.
The best time to check the engine oil level is about five
minutes after a fully warmed up engine is shut off. Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding one quart of oil when the reading is at
the bottom of the SAFE zone will result in a reading at the
top of the safe zone on these engines.
CAUTION!Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.
Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
