The Four-C system is based on a number of sensors that continuously monitor factors such as the car's lateral and
vertical movements, speed, and movements of the wheels. The sensors receive data up to 500 times per second, which
is used to provide extremely fast and precise adjustment of each shock absorber. The system adjusts the stiffness of the
shock absorbers approximately 100 times per second.
Use the button in the center console to switch between the driving modes Comfort and Sport. This can be
done at any time.
Comfort
The Comfort mode chassis setting offers the greatest amount of shock absorption and the softest ride. This mode is
recommended for long-distance driving, or when driving in slippery conditions. The indicator light in the button will
be off when this mode is selected. If Comfort mode was selected when the engine was switched off, this mode will still
be active when the engine is restarted.
Sport
In this mode, shock absorption is stiffer to reduce the car's body sway during cornering and to provide more immediate
steering response. The indicator light in the button will come on to indicate that Sport mode has been selected.
If this setting was selected when the engine was switched off, Sport mode will still be active when the engine is
restarted.
Advanced sport (V70 R only)
In this mode, movement of the shock absorbers is minimal, response from pressure on the throttle pedal is more direct,
and body sway in curves or when cornering is sharply reduced. If Advanced sport mode was selected when the engine
was switched off, Sport mode will be active when the engine is restarted.

If a fault should occur in the system, the LED in the button will be switched off and a message will be displayed in the
text window.
Cleaning the sensors
For the system to function properly, the sensors in the front and/or rear bumpers should be kept clean. They can be
cleaned with car washing detergent and a sponge.
WARNING!
These systems are designed to be a supplementary aid when parking the vehicle. They are not, however, intended to
replace the driver's attention and judgement.
pg. 101 Driving economy, Handling
Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stops and adjusting the speed of
your vehicle to immediate traffic conditions. Observe the following rules:
Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator
pedal for the first few minutes of operation. A cold engine uses more fuel and is subject to increased wear.
Whenever possible, avoid using the car for driving short distances. This does not allow the engine to reach normal
operating temperature.
Drive carefully and avoid rapid acceleration and hard braking.
Do not exceed posted speed limits.
Avoid carrying unnecessary items (extra load) in the car.
Maintain correct tire pressure. Check tire pressure regularly (when tires are cold).
Remove snow tires when threat of snow or ice has ended.
Note that roof racks, ski racks, etc., increase air resistance and fuel consumption.
Avoid using automatic transmission kickdown feature unless necessary.
Avoid using the air conditioning when it is not required. When engaged, the A/C compressor places an additional
load on the engine. However, at higher driving speeds, fuel consumption will be lower with the air conditioning on and
the windows closed than with the air conditioning off and the windows open.
Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically.
Other factors that decrease gas mileage are:
Dirty air cleaner
Dirty engine oil and clogged oil filter
Dragging brakes
Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard Maintenance Service intervals.
NOTE: Vehicles equipped with automatic transmissions should use (D)rive as often 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 highest gear that still allows smooth acceleration.
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle handling. 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 permissible axle loads are not exceeded.
Speed-sensitive power steering
(Option on certain models)
ProCarManuals.com

With this feature, the steering is most responsive at lower speeds to make parking, driving in city traffic, etc., easier.
The effect of the power steering diminishes as you accelerate for greater stability at highway speeds.
Weight distribution affects handling
At the specified curb weight your car has a tendency to understeer, which 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 properties can alter with the vehicle load. The heavier the load on the rear of
the vehicle (e.g., heavily loaded (max. 220 lbs, 100 kg) cargo area or when towing a trailer, the less the tendency to
understeer.
pg. 102 Points to remember
Cooling system
The risk for engine overheating is greatest, especially in hot weather, when:
Towing a trailer up steep inclines for prolonged periods at wide open throttle and low engine rpm.
Stopping the engine suddenly after high speed driving (so-called "after-boiling" can occur).
To avoid overheating, the following rules should be followed:
Do not drive for prolonged periods at engine speeds above 4500 rpm if you are towing a trailer in hilly terrain.
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 following precautions should be taken:
Switch off the air conditioning system.
Pull off the road, away from traffic, stop the car and put the gear selector into neutral.
Switch the heater to full (maximum) position. Increase the engine speed 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 154
for information on checking and topping-up the coolant level.
CAUTION: Drive slowly and carefully if going through standing water (i.e. flooded roadways, etc.). Damage to the
engine could result if excess water is drawn in through the air intake system. Never drive the vehicle in water deeper
than 1 foot (300 mm). See the flood warning on page 5
.
WARNING!
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 to air flow to floor, windshield and side windows and blower control to its highest
setting.
Floor mats : An extra mat on the driver's floor can cause the accelerator pedal to catch. Check that the movement

run flat tires.
Tires of this type have specially reinforced sidewalls that make it possible to continue driving in the event of a drop in
inflation pressure. Tires of this type are mounted on special rims.
NOTE: Self supporting run flat tires are only available in conjunction with TPMS.
If a self supporting run flat tire should lose inflation pressure, the yellow TPMS warning symbol (
) in the instrument
panel lights up to alert the driver, and a message will be shown in the text window in the instrument panel.
If this occurs, reduce vehicle speed to a maximum of 50 mph (80 km/h). The vehicle can be driven approximately 50
miles (80 km), or somewhat farther if the vehicle is not heavily loaded. The tire should be replaced as soon as
possible.
Hard braking and sudden steering maneuvers should be avoided.
In certain cases, it may be difficult to see which self supporting run flat tire is defective. To determine which tire is
damaged, check the inflation pressure of all four tires.
WARNING!
• Only specially trained persons should mount self supporting run flat tires.
• If self supporting run flat tires are mounted, the vehicle must be equipped with a Tire Pressure Monitoring System.
• After a low pressure warning has been displayed, do not exceed 50 mph (80 km/h).
• Avoid severe cornering and hard braking, and minimize the distance traveled before replacing the self supporting
run flat tire.
• Self supporting run flat tires cannot be repaired. They must be replaced if damaged or punctured.

Tire designations
Federal law mandates that tire manufacturers place standardized information on the sidewall of all tires (see the
illustration).
The following information is listed on the tire sidewall:
The tire designation (the following figures are examples of a tire designation):
1. 215: the width of the tire (in millimeters) from sidewall edge to sidewall edge. The larger the number, the wider the
tire.

Charge air cooler (Intercooler)
Turbocharged engines employ a turbo-compressor to force air into the engine inlet manifold and a charge air cooler to
cool the compressed inlet air. The resulting increase in air flow raises pressure in the intake manifold and increases
engine power over that developed by A normally-aspirated engine. The charge air cooler (which resembles a radiator)
is located between the turbo-compressor and inlet manifold.
