It is also important to maintain a proper power steering fluid level in the
power steering fluid reservoir:
• Do not operate the vehicle with a low power steering pump fluid level.
See Power steering fluid in the Maintenance and Specifications
chapter.
• Some noise is normal during operation. If the noise is excessive, check
for low power steering pump fluid level before seeking service by your
authorized dealer.
• Heavy or uneven steering efforts may be caused by low power steering
pump fluid level. Check for low power steering pump fluid level before
seeking service by your authorized dealer.
• Do not fill the power steering pump reservoir above the maximum
level, as this may result in leaks from the reservoir. See Power
steering fluid in the Maintenance and Specifications chapter.
If the power steering system breaks down (or if the engine is 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
AIR SUSPENSION SYSTEM (IF EQUIPPED)
The air suspension system is designed to improve ride, handling and
general vehicle performance during:
• Certain road conditions
• Steering maneuvers
• Braking
• Accelerations
