lower with the air conditioning on and the windows closed than with the \
air conditioning off and the
windows open.
l Using the onboard trip computer's fuel consumption modes can help you le\
arn how to drive more
economically.
Other factors that decrease gas mileage are:
l Dirty air cleaner
l Dirty engine oil and clogged oil filter
l Dragging brakes
l Incorrect front end alignment Some of the above mentioned items and othe\
rs are checked at the
standard Maintenance Service intervals.
NOTE: Vehicles equipped with automatic transmissions should use (D)rive as o\
ften as possible and
avoid using "kick-down" to help improve fuel economy. Vehicles equipped \
with manual transmissions
should use fifth gear at highway speeds. At other times, choose the high\
est gear that still allows smooth
acceleration.
Weight distribution affects handling
At the specified curb weight your car has a tendency to understeer, whic\
h means that the steering wheel
has to be turned more than might seem appropriate for the curvature of a\
bend. This ensures good
stability and reduces the risk of rear wheel skid. Remember that these p\
roperties can alter with the
vehicle load. The heavier the load on the rear of the vehicle (e.g., he\
avily loaded (max. 220 lbs, 100 kg)
cargo area or when towing a trailer, the less the tendency to understeer\
.
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle hand\
ling. Therefore, check that the tires
are inflated to the recommended pressure according to the vehicle load. \
See "Tire pressure" section.
Loads should be distributed so that capacity weight or maximum permissib\
le axle loads are not
exceeded.

pg. 96 Points to remember
Cooling system
The risk for engine overheating is greatest, especially in hot weather, \
when:
l Towing a trailer up steep inclines for prolonged periods at wide open th\
rottle and low engine rpm.
l Stopping the engine suddenly after high speed driving (so-called "after\
-boiling" can occur).
l To avoid overheating, the following rules should be followed: Do not dri\
ve for prolonged periods at

engine speeds above 4500 rpm if you are towing a trailer in hilly terrai\
n.
Reduce speed when towing a trailer up long, steep inclines. The risk of \
overheating can be reduced by
switching off the air conditioning system for a short time.
Do not let the engine idle unnecessarily for prolonged periods.
Do not mount auxiliary lamps in front of the grill.
When the risk of overheating is imminent, or in the event of overheating\
(the temperature gauge goes
repeatedly into, or stays continually in, the red section), the followi\
ng precautions should be taken:
l Switch off the air conditioning system.
l Pull off the road, away from traffic, stop the car and put the gear sele\
ctor into neutral.
l Switch the heater to full (maximum) position. Increase the engine spee\
d to approx. 2000 rpm (twice
idling speed) until the temperature begins to drop.
WARNING!
Do not remove coolant expansion tank cap. The coolant will be extremely \
hot.
If necessary, see
page 129 and 132 for information on checking and topping-up the coolant
level.
CAUTION: Drive slowly and carefully if going through standing water (i.e. flood\
ed roadways, etc.).
Damage to the engine could result if excess water is drawn in through th\
e air intake system. Never drive
the vehicle in water deeper than 1 foot (300 mm). See the flood warnin\
g on
page 7.
WARNING!
l Driving with the tailgate open: Driving with the tailgate open could mean that poisonous exhaust
gases enter the passenger compartment.
If the tailgate must be kept open for any reason, proceed as follows:
- Close the windows.
- Set the ventilation system control to air flow to floor, windshield an\
d side windows and blower
control to its highest setting.
l Floor mats: An extra mat on the driver's floor can cause the accelerator pedal to \
catch. Check that
the movement of the accelerator pedal is not impeded. Not more than one \
protective floor covering
may be used at one time.

charcoal canister to the engine's air intake system and into the combust\
ion process.
NOTE:
l Overfilling the fuel tank can cause damage to the evaporative control sy\
stem.
l If the fuel filler cap is not closed tightly or if the engine is running\
when the car is refueled, the
Malfunction Indicator Lamp may indicate a fault.
l During a transitional period, a small number of service stations may sti\
ll have fuel nozzles that are not
compatible with the fuel filler neck on cars equipped with the evaporati\
ve emission control system
mandated by the U.S. Environmental Protection Agency and the California \
Air Resources Board. If you
experience difficulties in refueling your vehicle, please ask the gas st\
ation attendant for assistance.
CAUTION:
Fuel must not be siphoned from the fuel tank. This will damage the evapo\
rative control system.

pg. 131 Drive belt, Coolant
Belt check
Check the belt regularly to make sure it is in good condition and is cle\
an. A worn or dirty belt can cause
poor cooling and low alternator output as well as impair the operation o\
f the power steering and the air
conditioning unit.
NOTE: The drive belt is equipped with a self-tensioning mechanism and requires\
no adjustment
between changes.
WARNING!
The engine must not be running when this check is
performed.
Check coolant level
The cooling system must be filled with coolant and not leak to operate a\
t maximum efficiency. Check
the coolant level regularly. The level should be between the "MAX" and "\
MIN" marks on the expansion
tank. The check should be made with particular thoroughness when the eng\
ine is new or when the
cooling system has been drained. Do not remove the filler cap other than\
for topping up with coolant.
Frequent removal may prevent coolant circulation between the engine and \
the expansion tank during
