{ CAUTION
Heater and radiator hoses, and other engine parts, can be very hot. Do not touch them. If you do, you can be burned. Do not run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle.
Notice: Using coolant other than DEX-COOL® can cause premature engine, heater core, or radiator corrosion. In addition, the engine coolant could require changing sooner, at 30,000 miles (50 000 km) or 24 months, whichever occurs first. Any repairs would not be covered by the vehicle warranty. Always use DEX-COOL® (silicate-free) coolant in the vehicle.
Engine Coolant The cooling system in the vehicle is filled with DEX-COOL® engine coolant. This coolant is designed to remain in the vehicle for five years or 150,000 miles (240 000 km), whichever occurs first. The following explains the cooling system and how to check and add coolant when it is low. If there is a problem with engine overheating, see Engine Overheating on page 9-20.

Vehicle Service and Care
What to Use
{ CAUTION
Adding only plain water to the cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. The vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, the engine could get too hot but you would not get the overheat warning. The engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and DEX-COOL® coolant.
Use a 50/50 mixture of clean, drinkable water and DEX-COOL® coolant. If using this mixture, nothing else needs to be added. This mixture: (cid:127) Gives freezing protection down
to −34°F (−37°C), outside temperature.
(cid:127) Gives boiling protection up to
265°F (129°C), engine temperature.
(cid:127) Protects against rust and
corrosion.
(cid:127) Will not damage aluminum parts. (cid:127) Helps keep the proper engine
temperature.
If an improper coolant
Notice: mixture is used, the engine could overheat and be badly damaged. The repair cost would not be covered by the vehicle warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core, and other parts. Notice: If extra inhibitors and/or additives are used in the vehicle’s cooling system, the vehicle could be damaged. Use only the proper mixture of the engine coolant listed in this manual for the cooling system. See Recommended Fluids and Lubricants on page 11-12 for more information.
Checking Coolant The vehicle must be on a level surface when checking the coolant level. Check to see if coolant is visible in the coolant recovery tank. If the coolant inside the coolant recovery tank is boiling, do not do anything else until it cools down. If coolant is visible but the coolant level is not at or above the COLD mark, add a 50/50 mixture of clean, drinkable water and DEX-COOL® coolant at the coolant recovery tank, but be sure the cooling system is cool before this is done. See Engine Coolant Engine Coolant for more information.
Vehicle Service and Care
9-17
The coolant reservoir is located in the engine compartment on the passenger side of the vehicle. See Engine Compartment Overview on page 9-6 for more information on location. The coolant level should be at or above the top mark on the coolant reservoir dipstick. If it is not, you may have a leak in the cooling system.
How to Add Coolant to the Recovery Tank
{ CAUTION
You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine.
Notice: This vehicle has a specific coolant fill procedure. Failure to follow this procedure could cause the engine to overheat and be severely damaged. If coolant is needed, add the proper DEX-COOL® coolant mixture at the coolant recovery tank.

Vehicle Service and Care
Engine Overheating The vehicle has an indicator to warn of engine overheating. There is an engine coolant temperature warning light on your vehicle’s instrument panel. See Engine Coolant Temperature Gage on page 4-17. You may decide not to lift the hood when this warning appears, but instead get service help right away. See Roadside Assistance Program on page 12-6. If you do decide to lift the hood, make sure the vehicle is parked on a level surface.
Then check to see if the engine cooling fans are running. If the engine is overheating, both fans should be running. If they are not, do not continue to run the engine and have the vehicle serviced. Notice: Engine damage from running the engine without coolant is not covered by the warranty. Notice: because of being driven with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by the vehicle warranty.
If the engine catches fire
If Steam Is Coming From The Engine Compartment { CAUTION
Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool.
Vehicle Service and Care
9-21
If the temperature overheat gage is no longer in the overheat zone or an overheat warning no longer displays, the vehicle can be driven. Continue to drive the vehicle slow for about 10 minutes. Keep a safe vehicle distance from the car in front of you. If the warning does not come back on, continue to drive normally. If the warning continues, pull over, stop, and park the vehicle right away. If there is no sign of steam, idle the engine for three minutes while parked. If the warning is still displayed, turn off the engine until it cools down. Also, see ‘‘Overheated Engine Protection Operating Mode’’ later in this section.
Power Steering Fluid Power Steering Fluid Level Power steering fluid is used in all vehicles. Check the level after the vehicle has been driven for at least twenty minutes so the fluid is warm. How to Check Power Steering Fluid To check the power steering fluid, do the following: 1. Turn the key off and let the engine
compartment cool down.
2. The power steering fluid reservoir
is located on the driver side toward the front of the engine compartment. See Engine Compartment Overview on page 9-6.
If No Steam Is Coming From The Engine Compartment If an engine overheat warning is displayed but no steam can be seen or heard, the problem may not be too serious. Sometimes the engine can get a little too hot when the vehicle: (cid:127) Climbs a long hill on a hot day. (cid:127) Stops after high-speed driving. (cid:127) Idles for long periods in traffic. (cid:127) Tows a trailer. If the overheat warning is displayed with no sign of steam: 1. Turn the air off. 2. Turn the heater on to the highest
temperature and to the highest fan speed. Open the windows as necessary.
3. In heavy traffic, let the engine idle
in N (Neutral) while stopped. If it is safe to do so, pull off the road, shift to P (Park) or N (Neutral) and let the engine idle.

Adding Washer Fluid
Windshield Washer Fluid What to Use When you need windshield washer fluid, be sure to read the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing.
Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview on page 9-6
for reservoir location.Notice: (cid:127) When using concentrated
washer fluid, follow the manufacturer’s instructions for adding water.
(cid:127) Do not mix water with
ready-to-use washer fluid. Water can cause the solution to freeze and damage your washer fluid tank and other parts of the washer system. Also, water does not clean as well as washer fluid.
(cid:127) Fill the washer fluid tank only
three-quarters full when it is very cold. This allows for fluid expansion if freezing occurs, which could damage the tank if it is completely full.
(cid:127) Do not use engine coolant
(antifreeze) in your windshield washer. It can damage the vehicle’s windshield washer system and paint.

(cid:127) A fluid leak in the brake hydraulic system can also cause a low fluid level. Have the brake hydraulic system fixed, since a leak means that sooner or later the brakes will not work well.
Do not top off the brake fluid. Adding fluid does not correct a leak. If fluid is added when the linings are worn, there will be too much fluid when new brake linings are installed. Add or remove brake fluid, as necessary, only when work is done on the brake hydraulic system.
{ CAUTION
If too much brake fluid is added, it can spill on the engine and burn, if the engine is hot enough. You or others could be burned, and the vehicle could be damaged. Add brake fluid only when work is done on the brake hydraulic system.
When the brake fluid falls to a low level, the brake warning light comes on. See Brake System Warning Light on page 4-15.
Brakes Brake Fluid
The brake master cylinder reservoir is filled with DOT-4 brake fluid. There are only two reasons why the brake fluid level in the reservoir might go down: (cid:127) The brake fluid level goes down because of normal brake lining wear. When new linings are installed, the fluid level goes back up.
9-26
Vehicle Service and Care
What to Add Use only new DOT-4 brake fluid from a sealed container. It is recommended that the brake hydraulic system be flushed and refilled with new DOT-4 fluid at a regular maintenance service every two years. See Additional Required Services on page 11-6
and Recommended Fluids and Lubricants on page 11-12. Always clean the brake fluid reservoir cap and the area around the cap before removing it. This helps keep dirt from entering the reservoir.{ CAUTION
With the wrong kind of fluid in the brake hydraulic system, the brakes might not work well. This could cause a crash. Always use the proper brake fluid.
Notice: (cid:127) Using the wrong fluid can badly damage brake hydraulic system parts. For example, just a few drops of mineral-based oil, such as engine oil, in the brake hydraulic system can damage brake hydraulic system parts so badly that they will have to be replaced. Do not let someone put in the wrong kind of fluid. If brake fluid is spilled on the vehicle’s painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on the vehicle. If you do, wash it off immediately. See Exterior Cleaning on page 9-98.
(cid:127)
Brake Wear This vehicle has disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound can come and go or be heard all the time the vehicle is moving, except when applying the brake pedal firmly.
{ CAUTION
The brake wear warning sound means that soon the brakes will not work well. That could lead to an accident. When the brake wear warning sound is heard, have the vehicle serviced.
Vehicle Service and Care
9-27
Notice: Continuing to drive with worn-out brake pads could result in costly brake repair. Some driving conditions or climates can cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with the brakes. Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly tighten wheel nuts in the proper sequence to torque specifications in Capacities and Specifications on page 10-2. Brake linings should always be replaced as complete axle sets.
Brake Pedal Travel See your dealer/retailer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign that brake service might be required.
Brake Adjustment Every time he brakes are applied, with or without the vehicle moving, the brakes adjust for wear.
Replacing Brake System Parts The braking system on a vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking.
The vehicle was designed and tested with top-quality brake parts. When parts of the braking system are replaced — for example, when the brake linings wear down and new ones are installed — be sure to get new approved replacement parts. If this is not done, the brakes might not work properly. For example, if someone puts in brake linings that are wrong for the vehicle, the balance between the front and rear brakes can change — for the worse. The braking performance expected can change in many other ways if the wrong replacement brake parts are installed.

Vehicle Service and Care
Battery This vehicle has a maintenance free battery. When it is time for a new battery, see your dealer/retailer for one that has the replacement number shown on the original battery’s label. The battery is located in the trunk behind a trim panel on the driver’s side. Warning: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.
Headlamp Aiming The optical headlamp aiming system has been preset at the factory and should need no further adjustment However, if the vehicle is damaged adjustment may be necessary. If oncoming vehicles flash their high beams at you, this may also mean the vertical aim needs to be adjusted. It is recommended that the vehicle is taken to your dealer/retailer for service if the headlamps need to be re-aimed. It is possible however, to re-aim the headlamps as described.
Vehicle Storage
{ CAUTION
Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you are not careful. See Jump Starting on page 9-84 for tips on working around a battery without getting hurt.
Infrequent Usage: If the vehicle is driven infrequently, remove the black, negative (−) cable from the battery. This helps keep the battery from running down. Extended Storage: For extended storage of the vehicle, remove the black, negative (−) cable from the battery or use a battery trickle charger. This helps maintain the charge of the battery over an extended period of time.

If your tires have too much air (over-inflation), you can get the following: (cid:127) Unusual wear (cid:127) Poor handling (cid:127) Rough ride (cid:127) Needless damage from
road hazards
A vehicle specific Tire and Loading Information label is attached to the vehicle’s center pillar, below the driver’s door latch. This label lists the vehicle’s original equipment tires and the recommended cold tire inflation pressure for the tires when they are cold. The recommended cold tire inflation pressure, shown on the label,
is the minimum amount of air pressure needed to support your vehicle’s maximum load carrying capacity. For more information regarding how much weight your vehicle can carry, see Loading the Vehicle on page 8-30. How you load your vehicle affects vehicle handling and ride comfort. When driving with less than the maximum load capacity allowed for your vehicle, you can set tire inflation pressure to the recommended amounts shown in the following chart. Never load your vehicle with more weight than it was designed to carry.

When to Check Check your tires once a month or more. Do not forget the compact spare tire, if your vehicle has one. It should be at 60 psi (420 kPa). For more information about the vehicle’s compact spare tire, see Compact Spare Tire on page 9-83.
How to Check Use a good quality pocket-type gage to check tire pressure. You can’t tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they’re underinflated. Check the tire’s inflation pressure when the tires are cold. Cold means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem. Press the tire gage firmly onto the valve to get a pressure measurement. If the cold tire inflation pressure matches the recommended pressure on the Tire and Loading Information label, no further adjustment is necessary. If the inflation pressure is low, add air until you reach the recommended amount.
Vehicle Service and Care

Vehicles with P245/45R18 96V, 245/45R18 96V, or 245/40R19 94W size tires, require inflation pressure adjustment when driving the vehicle at speeds of 100 mph (160 km/h) or higher. Use the following chart to determine the cold tire inflation pressure when operating the vehicle under high-speed conditions.
If you overfill the tire, release air by pushing on the metal stem in the center of the tire valve. Recheck the tire pressure with the tire gage. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture.
High-Speed Operation
{ CAUTION
Driving at high speeds, 100 mph (160 km/h) or higher, puts an additional strain on tires. Sustained high-speed driving causes excessive heat build up and can cause sudden tire failure. You could have a crash and you or others could be killed. Some high-speed rated tires require inflation pressure adjustment for high speed operation. When speed limits and road conditions are such that a vehicle can be driven at high speeds, make sure the tires are rated for high speed operation, in excellent condition, and set to the correct cold tire inflation pressure for the vehicle load.
