STEERING
To help prevent damage to the power steering system:
• Never hold the steering wheel at its furthest turning points (until it
stops) for more than three to five seconds when the engine is running.
• Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
• Some noise is normal during operation. If excessive, check for low
power steering pump fluid level before seeking service by your dealer.
• Heavy or uneven efforts may be caused by low power steering fluid.
Check for low power steering pump fluid level before seeking service
by your dealer.
• Do not fill the power steering pump reservoir above the MAX mark on
the reservoir, as this may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
• an improperly inflated tire
• uneven tire wear
• loose or worn suspension components
• loose or worn steering components
• improper steering alignment Driving

POWER STEERING FLUID
Check the power steering fluid. Refer to scheduled maintenance
information. If adding fluid is necessary, use only MERCON  AT F.
• Gasoline engine shown; diesel
engine similar. Refer to
Identifying components in the
engine compartment in the
diesel supplement.
Check the fluid level when it is at ambient temperature, 20°F–80°F
(-7°C–25°C):
1. Check the fluid level in the reservoir. It should be between the MIN
and MAX range. Do not add fluid if the level is within this range.
2. If the fluid level is low. Add fluid to bring fluid level up to be between
the MIN and MAX range.
3. Start the engine.
4. While the engine idles, turn the steering wheel left and right several
times.
5. Turn the engine off.
6. Recheck the fluid level in the reservoir. Do not add fluid if the level is
between the MIN and MAX range.
7. If the fluid is low, add fluid in small amounts, continuously checking
the level until it is between the MIN and MAX range. Refer to
Maintenance products specifications and capacities in this chapter for
the proper fluid type. Be sure to put the cap back on the reservoir. Maintenance and Specifications

Be sure to ask your dealership service advisor or technician about the
multi-point vehicle inspection. It’s a comprehensive way to perform a
thorough inspection of your vehicle. It’s your checklist that gives you
immediate feedback on the overall condition of your vehicle. You’ll know
what’s been checked, what’s okay, as well as those things that may
require future or immediate attention. The multi-point vehicle inspection
is one more way to keep your vehicle running great!Scheduled Maintenance
