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: Inspect the wheel pilot hole
prior to installation. If there is
visible corrosion in wheel pilot hole,
remove loose particles by wiping
with clean rag and apply grease.
Apply grease only to the wheel pilot
hole surface by smearing a “dime”
(1 square cm) sized glob of grease
around the wheel pilot surface (1)
with end of finger. DO NOT apply
grease to lugnut/stud holes or
wheel-to-brake surfaces.
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.

•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.
• 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.
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.
See Adding 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.
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 automatic transmission
vehicle. Automatic transmissions do not have push-start
capability. Attempting to push-start a vehicle with an automatic
transmission may cause transmission damage.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
automatic transmission must relearn its shift strategy. As a result, the

4. Make the final connection of the negative (-) cable to an exposedmetal 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.
3. Once the disabled vehicle has been started, run both engines for an additional three minutes before disconnecting the jumper cables.
