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
AUTOMATIC TRANSMISSION OPERATION
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the on position unless the brake pedal is applied. If you cannot move
the gear lever out of P (Park) when the ignition is on and the brake
pedal applied, it is possible that a fuse has blown or the vehicle’s brake
lamps are not operating properly. Refer to Fuses and relays in the
Roadside Emergencies chapter.
WARNING: Do not drive your vehicle until you verify that the
brakelamps are working.
