µIf you exceed the maximum speed
f or the gear you are in, the engine
speed will enter into the tachometer’s
red zone. If this occurs, you may f eel
the engine cut in and out. This is
caused by a limiter in the engine’s
computer controls. The engine will
run normally when you reduce the
rpm below the red zone.
Bef ore downshif ting, make sure the
engine will not go into the
tachometer’s red zone.
This position is
similar to D, except only the f irst
three gears are selected. Use D
when towing a trailer in hilly terrain,
or to provide engine braking when
going down a steep hill. D can also
keep the transmission f rom cycling
between third, f ourth, and f if th gears
in stop-and-go driving.
ForfasteraccelerationwheninD or
D, you can get the transmission to
automatically downshif t by pushing
the accelerator pedal to the floor.
The transmission will shif t down one,
two, or three gears, depending on
your speed. This allows you to move the shif t
lever out of Park if the normal
method of pushing on the brake
pedal and pressing the release
button does not work.
Remove the key from the ignition
switch.
Set the parking brake.

Check the indicator on the
instrument panel to verif y that the
security system is set.
If the vehicle is f acing uphill, turn
the front wheels away from the
curb.
Never park over dry leaves, tall
grass, or other f lammable
materials. The hot three way
catalytic converter could cause
these materials to catch on fire.
Make sure the parking brake is
f ully released bef ore driving away.
Driving with the parking brake
partially set can overheat or
damage the rear brakes.
Make sure the moonroof and the
windows are closed.
Turn of f the lights.
Place any packages, valuables, etc.
in the cargo area or take them
with you.
Lock the doors and the tailgate.
Always use the parking brake when
you park your vehicle. Make sure
the parking brake is set f irmly, or
your vehicle may roll if it is parked
on an incline.
Set the parking brake bef ore you put
the transmission in Park. This keeps
the vehicle from moving and putting
pressure on the parking mechanism
in the transmission. If the vehicle is f acing downhill,
turn the front wheels toward the
curb.

not have the active damper function.Your vehicle has been designed
primarily to carry passengers and
their cargo. You can also use it to
tow a trailer if you caref ully observe
the load limits, use the proper
equipment, and f ollow the guidelines
in this section.

The weight that the tongue of a f ully
loaded trailer puts on the hitch
shouldbe5to10percentof thetotal
trailer weight f or boat trailers, and 8
to 15 percent of total trailer weight
f or all other trailers. (See page
f or limits f or your towing
situation). Too much tongue load
reduces front-tire traction and
steering control. Too little tongue
load can make the trailer unstable and cause it to sway.
The maximum
allowable weight of the vehicle, all
occupants, all accessories, all cargo,
and the tongue load must not exceed
2,888 lbs (1,310 kg) on the f ront axle,
and 3,175 lbs (1,440 kg) on the rear
axle. The maximum
allowable weight of the vehicle, all
occupants, all accessories, all cargo
and the tongue load is 5,952 lbs
(2,700 kg).
The maximum allowable weight of
the trailer and everything in or on it
depends on the number of occupants
inyourvehicleandthetypeof trailer
being towed (see page ).
Towing a trailer that is too heavy can
seriously af f ect your vehicle’s
handling and perf ormance. It can
also damage the engine and
drivetrain. The maximum
allowable weight of the f ully loaded
vehicle and trailer is 10,053 lbs
(4,560 kg) with the proper hitch. The
GCWR must be reduced 2 percent
f or every 1,000 f eet (305 meters) of
elevation.

Park the vehicle on level ground.
Measure and record the distance
from the ground to the bottom of
the trailer hitch.
Connect the f ully loaded trailer to
the hitch.
Measure again f rom the ground to
the same spot on the bottom of the
hitch.
Subtract the second measurement
from the first measurement, then
ref er to the f ollowing table.
Thebestwaytoconfirmthatall
loads are within limits is to check
them at a public scale. For public
scales in your area, check your local
phone book, or contact your trailer
dealer or rental agency for
assistance.
Estimated
tongue load is:
150 lbs (68 kg)
250 lbs (114 kg)

If thedifferenceismorethan1½

Add the weight of your trailer (as
quoted by the manuf acturer) with
everything in or on the trailer. Then
check the tables on page to
make sure you do not exceed the
limit f or your conditions.
To help ensure a saf e drive to a scale,
or if you cannot get to a public scale,
we recommend that you estimate

Total Trailer Weight and Tongue Load Limits:
The corresponding weight limits assume occupants fill seats from the front of the vehicle to the back, each occupant weighs 150 lbs (70 kg),
and each has 15 lbs (7 kg) of cargo in the cargo area. Any additional weight, including cargo or accessories, reduces the maximum trailer
weight and maximum tongue load. Never exceed the gross axle weight ratings (see page ).
Recommended tongue load should be 5 15% of the total trailer weight for boat trailers, and 8 15% of the total trailer weight for all other
trailers.

To accurately check your loads at
the public scale, the vehicle and
trailer should be f ully loaded, and all
occupants should stay in the vehicle
while the attendant watches the
scale.Check the rear gross axle weight.
Limit: 3,175 lbs (1,440 kg)
If you cannot weigh the rear axle
directly, you can calculate the rear
gross axle weight by subtracting
the weight in step 1 from the
weight in step 2.Remember, maximum gross
combined weight should be
decreased 2 % f or every 1,000 f eet
(305 meters) of elevation.
Check the f ront gross axle weight.
