4. If your vehicle is equipped with P265/75 R15 AT tires, do not stow aflat or inflated full size spare tire in the spare tire carrier. The flat
full size tire should be stowed and tied down in the pickup box bed
until it can be repaired.
5. If removed, install the spare tire carrier lock on the access hole above the bumper.
Tire change procedure WARNING: When one of the front wheels is off the ground, the
transmission alone will not prevent the vehicle from moving or
slipping off the jack, even if the vehicle is in P (Park)
(automatic transmission) or R (Reverse) (manual
transmission).
WARNING: To help prevent the vehicle from moving when you
change a tire, be sure the parking brake is set, then block (in
both directions) the wheel that is diagonally opposite (other
side and end of the vehicle) to the tire being changed.
WARNING: If the vehicle slips off the jack, you or someone
else could be seriously injured.
1. Park on a level surface, activate hazard flashers and place
gearshift lever in P (Park)
(automatic transmission) or 1
(First) (manual transmission).
2. Set the parking brake and turn engine OFF.

3. Block the diagonally oppositewheel.
4. Insert tapered end of the lug wrench behind hub caps and
twist them off.
5. Loosen each wheel lug nut one-half turn counterclockwise
but do not remove them until
the wheel is raised off the
ground.
6. Position the jack according to the following guides and turn
the jack handle clockwise until the tire is a maximum of 1 inch (25
mm) off the ground.
WARNING: To lessen the risk of personal injury, do not put any
part of your body under the vehicle while changing a tire. Do
not start the engine when your vehicle is on the jack. The jack
is only meant for changing the tire.
WARNING: Do not let anyone stay in the vehicle when you are
using the jack; have them stand in a safe place out of traffic
lanes.

WARNING: When a wheel is installed, always remove any
corrosion, dirt or foreign materials present on the mounting
surfaces of the wheel or the surface of the wheel hub, brake
drum or brake disc that contacts the wheel. Ensure that any
fasteners that attach the rotor to the hub are secured so they
do not interfere with the mounting surfaces of the wheel.
Installing wheels without correct metal-to-metal contact at the
wheel mounting surfaces can cause the wheel nuts to loosen
and the wheel to come off while the vehicle is in motion,
resulting in loss of control.
Note: If there is corrosion on the area where the wheel contacts the
hub, apply a thin film of grease or anti-seize compound on that area.
OVERHEATING
If the temperature gauge indicates overheating and you experience
power loss, you hear a loud knocking or pinging noise, the engine is
probably too hot.
If this happens:
1. Drive safely to the side of the road and park off the right-of-way.
2. Shift the automatic transmission into P (Park) or the manual transmission into the neutral position, and apply the parking brake.
3. Turn off the air conditioner.
WARNING: Steam from an overheated engine is dangerous. The
escaping steam could seriously burn you. Open the hood ONLY
after steam is no longer escaping from the engine.
4. Check whether coolant or steam is escaping from under the hood or from the engine compartment.
² If steam is coming from the engine compartment: do not go near
the front of the vehicle. Stop the engine, then turn the ignition switch
to the ON position without starting the engine. The radiator cooling
fans will start to cool the engine.
² If neither coolant nor steam is escaping: open the hood and idle
the engine until it cools. If this does not lower the temperature, stop
the engine and let it cool.
5. Check the coolant level. If it is low, look for leaks in the radiator hoses and connections, heater hoses and connections, radiator and
water pump.

If you find a leak or other damage, or if coolant is still leaking, stop the
engine and call an authorized dealer.
SeeAdding coolant in theMaintenance and Specifications section. If
you find no problems, the engine is cool and no leaks are obvious,
carefully add coolant as required.
WARNING: When the engine and radiator are hot, scalding
coolant and steam may shoot out under pressure and cause
serious injury. Do not remove the cooling system cap when the
engine and radiator are hot.
Note: If the engine continues to overheat or frequently overheats, have
the cooling system inspected. The engine could be seriously damaged
unless repairs are made.
JUMP STARTING
WARNING: The gases around the battery can explode if
exposed to flames, sparks, or lit cigarettes. An explosion could
result in injury or vehicle damage.
WARNING: Batteries contain sulfuric acid which can burn skin,
eyes and clothing, if contacted.
Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; doing so may
damage the catalytic converter.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
transmission must relearn its shift strategy. As a result, the transmission
may have firm and/or soft shifts. This operation is considered normal and
will not affect function or durability of the transmission. Over time, the
adaptive learning process will fully update transmission operation. 1. Use only a 12±volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could damage the vehicle's electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle making sure the two vehicles do nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other
moving parts.

3. Connect the negative (-) cable to the negative (-) terminal of theassisting battery.
4. Make the final connection of the negative (-) cable to an exposed metal part of the stalled vehicle's engine, away from the battery and
the fuel injection system. Do notuse fuel lines, engine rocker covers
or the intake manifold as groundingpoints.
WARNING: Do not connect the end of the second cable to the
negative (-) terminal of the battery to be jumped. A spark may
cause an explosion of the gases that surround the battery.
5. Ensure that the cables are clear of fan blades, belts, moving parts of both engines, or any fuel delivery system parts.
Jump starting 1. Start the engine of the booster vehicle and run the engine at moderately increased speed.
2. Start the engine of the disabled vehicle.
