When Towing a Trailer
•
Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission in park (P) or neutral (N)
to aid engine and transmission cooling
and to help air conditioning
performance.
• Switch off the speed control with
heavy loads or in hilly terrain. The
speed control may turn off
automatically when you are towing on
long, steep grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a slope. However, if
you must park on a slope:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission in park (P) or manual transmission in a
low gear. 4. Place wheel chocks in front and back
of the trailer wheels. Chocks are not
included with your vehicle.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before
backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than
6 in (15 cm) above the bottom
edge of the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Any time the rear axle submerges in water,
replace the rear axle lubricant. Water may
contaminate the rear axle lubricant, which
is not a normal maintenance inspection
item unless there is a possibility of a leak
or other axle repair is required.
TOWING THE VEHICLE ON
FOUR WHEELS
Emergency Towing WARNING
If your vehicle has a steering wheel
lock make sure the ignition is in the
accessory or on position when being
towed. 197

BREAKING-IN
Tires
New tires need to be run-in for
approximately 300 mi (500 km). During
this time, you may experience different
driving characteristics.
Brakes and Clutch
Avoid heavy use of the brakes and clutch
if possible for the first
100 mi (150 km) in
town and for the first 1,000 mi (1,500 km)
on freeways.
Engine
Avoid driving too fast during the first
1,000 mi (1,500 km)
. Vary your speed
frequently and change up through the
gears early. Do not labor the engine.
REDUCED ENGINE
PERFORMANCE WARNING
If you continue to drive your vehicle
when the engine is overheating, the
engine could stop without warning.
Failure to follow this instruction could
result in the loss of control of your vehicle. If the engine coolant temperature gauge
needle moves to the upper limit position,
the engine is overheating. See
Gauges
(page 81).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on
ambient temperature, vehicle load and
terrain. The engine continues to operate
with limited power for a short period of
time. If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually.
1. Gradually reduce your speed and stop
your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See
Engine
Coolant Check (page 234).
5. Have your vehicle checked as soon as possible.
ECONOMICAL DRIVING
Fuel economy is affected by several things
such as how you drive, the conditions you
drive under and how you maintain your
vehicle.
There are some things to keep in mind that
may improve your fuel economy:
• Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving (When running
errands, go to the furthest destination
first and then work your way back
home).
• Close the windows for high-speed
driving.
• Drive at reasonable speeds.
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.

ENGINE COOLANT CHECK
WARNINGS
Do not remove the coolant reservoir
cap when the cooling system is hot.
Wait 10 minutes for the cooling
system to cool down. Cover the coolant
reservoir cap with a thick cloth to prevent
the possibility of scalding and slowly
remove the cap. Failure to follow this
instruction could result in personal injury. Do not put coolant in the windshield
washer reservoir. If sprayed on the
windshield, coolant could make it
difficult to see through the windshield. To reduce the risk of personal injury,
make sure the engine is cool before
unscrewing the coolant pressure
relief cap. The cooling system is under
pressure. Steam and hot liquid can come
out forcefully when you loosen the cap
slightly. Do not add coolant further than the
MAX mark.
When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance
(page 438).
Note: Make sure that the coolant level is
between the
MIN and MAX marks on the
coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between
-29°F (-34°C) and -35°F
(-37°C). Coolant concentration should be
checked using a refractometer. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration. Adding Coolant WARNINGS
Do not add engine coolant when the
engine is hot. Failure to follow this
instruction could result in personal
injury. Do not remove the coolant reservoir
cap when the cooling system is hot.
Wait 10 minutes for the cooling
system to cool down. Cover the coolant
reservoir cap with a thick cloth to prevent
the possibility of scalding and slowly
remove the cap. Failure to follow this
instruction could result in personal injury. Note:
Automotive fluids are not
interchangeable. Take care not to put
engine coolant in the windshield washer
fluid reservoir or windshield washer fluid in
the engine coolant reservoir.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
It is very important to use prediluted
coolant approved to the correct
specification in order to avoid plugging the
small passageways in the engine cooling
system. See
Capacities and
Specifications (page 290). Do not mix
different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine
or cooling system components and may
not be covered by the vehicle Warranty.
Note: If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water. See
Capacities and Specifications
(page 290).
Using water that has not been deionised
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways.
