Hyundai Sonata: Transmission / Good Driving Practices
- Never move the shift lever from P (Park) or N (Neutral) to any other position
with the accelerator pedal depressed.
- Never move the shift lever into P (Park) when the vehicle is in motion.
- Be sure the vehicle is completely stopped before you attempt to shift into
R (Reverse) or D (Drive).
- Do not move the shift lever to N (Neutral) when driving. Doing so may result
in an accident because of a loss of engine braking and the transmission could
be damaged.
- Do not drive with your foot resting on the brake pedal. Even light, but
consistent pedal pressure can result in the brakes overheating, brake wear and
possibly even brake failure.
- Depressing both accelerator and brake pedals at the same time can trigger
logic for engine power reduction to assure vehicle deceleration. Vehicle acceleration
will resume after the brake pedal is released.
- When driving in Manual shift mode, slow down before shifting to a lower
gear. Otherwise, the lower gear may not be engaged if the engine rpms are outside
of the allowable range.
- Always apply the parking brake when leaving the vehicle. Do not depend on
placing the transmission in P (Park) to keep the vehicle from moving.
- Exercise extreme caution when driving on a slippery surface. Be especially
careful when braking, accelerating or shifting gears. On a slippery surface,
an abrupt change in vehicle speed can cause the drive wheels to lose traction
and may cause loss of vehicle control resulting in an accident.
- Optimum vehicle performance and economy is obtained by smoothly depressing
and releasing the accelerator.
Information - Kickdown Mechanism
Use the kickdown mechanism for maximum acceleration. Depress the accelerator
pedal beyond the pressure point. The automatic transmission will shift to a lower
gear depending on the engine speed.
WARNING
If your vehicle becomes stuck in snow, mud, sand, etc., then you may attempt
to rock the vehicle free by moving it forward and backward. Do not attempt this
procedure if people or objects are anywhere near the vehicle. During the rocking
operation the vehicle may suddenly move forward or backward as it becomes unstuck,
causing injury or damage to nearby people or objects.
WARNING
To reduce the risk of SERIOUS INJURY or DEATH:
- ALWAYS wear your seatbelt. In a collision, an unbelted occupant is significantly
more likely to be seriously injured or killed than a properly belted occupant.
- Avoid high speeds when cornering or turning.
- Do not make quick steering wheel movements, such as sharp lane changes
or fast, sharp turns.
- The risk of rollover is greatly increased if you lose control of your
vehicle at highway speeds.
- Loss of control often occurs if two or more wheels drop off the roadway
and the driver over steers to reenter the roadway.
- In the event your vehicle leaves the roadway, do not steer sharply. Instead,
slow down before pulling back into the travel lanes.
- HYUNDAI recommends you follow all posted speed limits.
Moving up a steep grade from a standing start
To move up a steep grade from a standing start, depress the brake pedal, shift
the shift lever to D (Drive). Depress the accelerator gradually while releasing
the service brakes.
Always come to a complete stop and continue to depress the brake pedal. Move
the shift lever into the P (Park) position, apply the parking brake, and place the
ignition switch in the LOCK/OFF positi ...
