Faults in the system
If a fault should occur in the system, the LED in the button will be switched off and a message will be displayed in the
text window.
Cleaning the sensors
For the system to function properly, the sensors in the front and/or rear bumpers should be kept clean. They can be
cleaned with car washing detergent and a sponge.
WARNING!
These systems are designed to be a supplementary aid when parking the vehicle. They are not, however, intended to
replace the driver's attention and judgement.
pg. 84 Driving economy
Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stops and adjusting the speed of
your vehicle to immediate traffic conditions. Observe the following rules:
Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator
pedal for the first few minutes of operation. A cold engine uses more fuel and is subject to increased wear.
Whenever possible, avoid using the car for driving short distances. This does not allow the engine to reach normal
operating temperature.
Drive carefully and avoid rapid acceleration and hard braking.
Do not exceed posted speed limits.
Avoid carrying unnecessary items (extra load) in the car.
Maintain correct tire pressure. Check tire pressure regularly (when tires are cold).
Remove snow tires when threat of snow or ice has ended.
Note that roof racks, ski racks, etc., increase air resistance and also fuel consumption.
Avoid using automatic transmission kickdown feature unless necessary.
Avoid using the air conditioning when it is not required. When engaged, the A/C compressor places an additional
load on the engine. However, at higher driving speeds, fuel consumption will be lower with the air conditioning on and
the windows closed than with the air conditioning off and the windows open.
Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically.
Other factors that decrease gas mileage are:
Dirty air cleaner
Dirty engine oil and clogged oil filter
Dragging brakes
Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard Maintenance Service intervals.
NOTE : Vehicles equipped with automatic transmissions should use (D)rive as often as possible and avoid using
"kickdown" to help improve fuel economy.
Cooling system
The risk for engine overheating is greatest, especially in hot weather, when:
Towing a trailer up steep inclines for prolonged periods at wide open throttle and low engine rpm.
Stopping the engine suddenly after high speed driving (so-called "after-boiling" can occur).
To avoid overheating, the following rules should be followed:
Do not drive for prolonged periods at engine speeds above 4500 rpm if you are towing a trailer in hilly terrain.

characteristics. Therefore, all tires older than 6 years (including the spare tire and winter tires) should be inspected by a
qualified technician, regardless of appearance or mileage. Heat caused by hot climates or frequent high loading
conditions can accelerate the aging process.
A tire's age can be determined by the DOT stamp on the sidewall (see the illustration above).
A tire with e.g., visible cracks or discoloration should be replaced immediately.
Improving tire economy:
• Maintain correct tire pressure. See the tire pressure table on page 106.
• Drive smoothly: avoid fast starts, hard braking and tire screeching.
• Tire wear increases with speed.
• Correct front wheel alignment is very important.
• Unbalanced wheels impair tire economy and driving comfort.
• Tires must maintain the same direction of rotation throughout their lifetime.
• When replacing tires, the tires with the most tread should be mounted on the rear wheels to reduce the chance of
oversteer during hard braking.
Hitting curbs or potholes can damage the tires and/or wheels permanently.

Tire inflation
Check tire inflation pressure regularly.
A table listing the recommended inflation pressure for your vehicle can be found on page 106.
Tire inflation pressure
placards are also located on the driver's side B-pillar (the structural member at the side of the vehicle, at the rear of the
driver's door opening), or on the inside of the fuel filler door on Canadian models. These placards indicate the
designation of the factory-mounted tires on your vehicle, as well as load limits and inflation pressure.
