Speed sensitive steering
The steering in your vehicle is speed sensitive. At high speeds, steering
assist will decrease to improve steering feel. At lower speeds,
maneuverability will be increased.
If the amount of effort required to steer your vehicle changes at a
constant vehicle speed, have the power steering system checked by your
dealer or a qualified service technician.
TRACTION CONTROLY(IF EQUIPPED)
The Traction Controlysystem helps maintain the stability and
steerability of your vehicle. It is especially useful on slippery and/or hilly
road surfaces. The system operates at all speeds by detecting and
controlling wheel spin. The system borrows many of the electronic and
mechanical elements already present in the anti-lock braking system
(ABS).
Wheel-speed sensors allow excess rear wheel spin to be detected by the
Traction Controlyportion of the ABS computer. Any excessive wheel
spin is controlled by automatically applying and releasing the rear brakes
in conjunction with engine torque reductions. Engine torque reduction is
realized via the fully electronic spark and fuel injection systems. This
process is very sensitive to driving conditions and very fast acting. The
rear wheels ªsearchº for optimum traction several times a second and
adjustments are made accordingly.
The Traction Controlysystem will allow your vehicle to make better use
of available traction on slippery surfaces. The system is a driver aid
which makes your vehicle easier to handle primarily on snow and ice
covered roads. This is especially evident if wheel spin-up should occur
while turning.
During Traction Controlyoperation you may hear an electric motor type
of sound coming from the engine compartment and the engine will not
ªrev-upº when you push further on the accelerator. This is normal
system behavior.

Do not exceed the GVWR or the GAWR specified on the
certification label.
Do not use replacement tires with lower load carrying capacities than the
originals because they may lower the vehicle's GVWR and GAWR
limitations. Replacement tires with a higher limit than the originals do
not increase the GVWR and GAWR limitations.
The Certification Label, found on the inside pillar of the driver's door,
lists several important vehicle weight rating limitations. Before adding
any additional equipment, refer to these limitations. If you are adding
weight to the front of your vehicle, (potentially including weight added
to the cab), the weight added should not exceed the front axle reserve
capacity (FARC). Additional frontal weight may be added to the front
axle reserve capacity provided you limit your payload in other ways (i.e.
restrict the number of passengers or amount of cargo carried).
You may add equipment throughout your vehicle if the total weight
added is equal to or less than the total axle reserve capacity (TARC)
weight. You should NEVER exceed the total axle reserve capacity.
Always ensure that the weight of passengers, cargo and equipment being
carried is within the weight limitations that have been established for
your vehicle including both gross vehicle weight and Front and rear
gross axle weight rating limits. Under no circumstance should these
limitations be exceeded. Exceeding any vehicle weight rating limitation
could result in serious damage to the vehicle and/or personal injury.
TRAILER TOWING
Trailer towing with your vehicle may require the use of a trailer tow
option package.
Trailer towing puts additional loads on your vehicle's engine,
transmission, axle, brakes, tires, and suspension. For your safety and to
maximize vehicle performance, be sure to use the proper equipment
while towing.
Follow these guidelines to ensure safe towing procedure:
²Stay within your vehicle's load limits. If exceeded, cargo should be
removed from the trailer and/or the vehicle until all weights are within
specified limits.
²Thoroughly prepare your vehicle for towing. Refer toPreparing to
towin this chapter.

1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to a service facility.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
Never remove the coolant reservoir cap while the engine is
running or hot.
5. Re-start the engine and take your vehicle to a service facility.
Driving the vehicle without repairing the engine problem
increases the chance of engine damage. Take your vehicle to a
service facility as soon as possible.
Checking and adding engine cooling fan hydraulic fluid
Check the engine cooling fan hydraulic fluid. Refer to the Scheduled
Maintenance Guide for the service interval schedules. If adding fluid is
necessary, use only MERCONtAT F.
Check the fluid level when it is at
ambient temperature (-7É to 25É C
[20É to 80É F]):
1. Check the fluid level in the
reservoir. It should be between the
MIN and MAX lines. Do not add
fluid if the level is in this range.
2. If the fluid is low, add fluid in
small amounts, continuously
checking the level until it reaches
the range between the MIN and
MAX lines. Be sure to put the cap
back on the reservoir.

near the center of the normal area
between H and C).
2. While the engine idles, turn the
steering wheel left and right several
times.
3. Turn the engine off.
4. Check the fluid level in the
reservoir. It should be between the
MIN and MAX lines. Do not add
fluid if the level is in this range.
5. If the fluid is low, add fluid in
small amounts, continuously
checking the level until it reaches
the range between the MIN and
MAX lines. Be sure to put the cap
back on the reservoir.
TRANSMISSION FLUID
Checking automatic transmission fluid
The 5R55N transmission does not have a transmission fluid dipstick.
Refer to your Scheduled Maintenance Guide for scheduled intervals for
fluid checks and changes. Your transmission does not consume fluid.
However, the fluid level should be checked if the transmission is not
working properly, i.e., if the transmission slips or shifts slowly or if you
notice some sign of fluid leakage.
Transmission fluid should be checked and, if required, fluid should be
added by a qualified technician.
Before adding any fluid, make sure the correct type is used. The type of
fluid used is indicated on the transmission fluid pan, extension housing

ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fillups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend
taking fuel economy measurements during the first 1 600 km (1 000
miles) of driving (engine break-in period). You will get a more accurate
measurement after 3 000 km±5 000 km (2 000 miles-3 000 miles).
Filling the tank
The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in theRefill Capacities
section of theCapacities and specificationschapter.
The advertised capacity is the amount of the indicated capacity and the
empty reserve combined. Indicated capacity is the difference in the
amount of fuel in a full tank and a tank when the fuel gauge indicates
empty. Empty reserve is the small amount of usable fuel remaining in the
fuel tank after the fuel gauge indicates empty.
The amount of empty reserve varies and should not be relied
upon to increase driving range. When refueling your vehicle after
the fuel gauge indicates empty, you might not be able to refuel
the full amount of the advertised capacity of the fuel tank due to
the empty reserve still present in the tank.
For consistent results when filling the fuel tank:
²Use the same filling rate setting (low Ð medium Ð high) each time
the tank is filled.
²Allow three automatic click-offs when filling.
²Always use fuel with the recommended octane rating.
²Use a known quality gasoline, preferably a national brand.
²Use the same side of the same pump and have the vehicle facing the
same direction each time you fill up.
²Have the vehicle loading and distribution the same every time.
Your results will be most accurate if your filling method is consistent.
Maintenance and care

Calculating fuel economy
1. Fill the fuel tank completely and record the initial odometer reading
(in kilometers or miles).
2. Each time you fill the tank, record the amount of fuel added (in liters
or gallons).
3. After at least three to five tank fill-ups, fill the fuel tank and record
the current odometer reading.
4. Subtract your initial odometer reading from the current odometer
reading.
5. Follow one of the simple calculations in order to determine fuel
economy:
Multiply liters used by 100, then divide by total kilometers
traveled.
Divide total miles traveled by total gallons used.
Keep a record for at least one month and record the type of driving (city
or highway). This will provide an accurate estimate of the vehicle's fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter will show how temperature impacts fuel
economy. In general, lower temperatures give lower fuel economy.
Driving style Ð good driving and fuel economy habits
Give consideration to the lists that follow and you may be able to change
a number of variables and improve your fuel economy.
Habits
²Smooth, moderate operation can yield up to 10% savings in fuel.
²Steady speeds without stopping will usually give the best fuel
economy.
²Idling for long periods of time (greater than one minute) may waste
fuel.
²Anticipate stopping; slowing down may eliminate the need to stop.
²Sudden or hard accelerations may reduce fuel economy.
²Slow down gradually.
²Driving at reasonable speeds (traveling at 88 km/h [55 mph] uses 15%
less fuel than traveling at 105 km/h [65 mph]).
²Revving the engine before turning it off may reduce fuel economy.
Maintenance and care
233 

²Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
Cleaning the instrument panel
Clean with a damp cloth, then dry with a dry cloth.
Avoid cleaner or polish that increases the gloss of the upper portion of
the instrument panel. The dull finish in this area helps protect the driver
from undesirable windshield reflection.
Do not use chemical solvents or strong detergents when cleaning
the steering wheel or instrument panel to avoid contamination of
the air bag system.
Cleaning the instrument cluster lens
Clean with a damp cloth, then dry with a dry cloth.
Do not use household or glass cleaners as these may damage the lens.
Cleaning seats equipped with side air bags
Remove dust and loose dirt with a whisk broom or a vacuum cleaner.
Remove fresh spots immediately. Follow the directions that come with
the cleaner. Do not saturate the seat cover with upholstery cleaner.
Do not use chemical solvents or strong detergents when cleaning
the seat mounted side air bag. Such products could contaminate
the side air bag system and affect performance of the side air bag in a
collision.
Woodtone trim
Wipe stains with a soft cloth and a multi-purpose cleaning solution.
Inside windows
Use Ultra-Clear Spray Glass Cleaner (E4AZ-19C507±AA) for the inside
windows if they become fogged.
Cleaning and maintaining the safety belts
Clean the safety belts with a mild soap solution recommended for
cleaning upholstery or carpets. Do not bleach or dye the belts, because
these actions may weaken the belt webbing.
